It’s not vanity and it’s not easy: NHS agrees

Posted on by

As reported on Sky News and the New York Times, there has been a radical turn around regarding the use of bariatric surgery to prevent/ control and even “cure” diabetes.

vanity

Not a vanity procedure

Once relegated to the category of a” vanity” procedure, bariatric surgery has emerged as a legitimate,  life-saving intervention which has been scientifically proven to have multiple major health benefits.

For years, patients have had to jump numerous hurdles to be considered for this procedure.  One of the biggest hurdles was often that patients were not considered fat enough to qualify for this procedure.  The traditional guidelines restricted surgery to morbidly obese people, and then required these patients to perform numerous tasks to be considered eligible candidates of surgery such as attaining a diagnosis of “carbohydrate addiction” and losing weight prior to surgery as a sign of “commitment” to weight loss.  This was in addition to several months of therapy with nutritionists and counselors.

hoops

A punitive process

While including this ancillary education may have assisted patients post-operatively, it also felt punitive to people who were seeking medical help.  No one forces lung cancer patients to attend smoking cessation courses or counselling before having their cancer treatment nor do we require several sessions of pre-operative classes prior to a bowel resection.

No, not this kind of scale

New guidelines – perform surgery earlier (2012)

But as the data started to emerge that showed long-lasting health benefits of surgery-assisted weight loss, debates raged between International and American physicians.  Several years ago, several international organizations such as the International Diabetes Federation began to recommend lowering the eligibility criteria for bariatric surgery – particularly for patients with documented complications of obesity present (diabetes, coronary artery disease, severe orthopedic injuries).  But these recommendations were ignored by American medical societies and many physicians including the doctors responsible for initiating referrals to bariatric surgery programs.  Americans. it seemed were reserving the the more effective treatments (like gastric bypass or gastric sleeve) for the super-obese, and the prototypical 600 pound patients.

Obese patients who did not meet these rigid guidelines were often sent for less effective procedures like lap-band or balloon placement.  Insurance companies often denied payment stating that surgery in these patients were ‘not medically necessary’  and thus it was considered a ‘vanity’ procedure.  Additionally, in most cases, the procedures failed to produce meaningful or long-lasting results.

Adding stigma and shame to a medical condition

Patients who were overweight  and seeking definitive treatment were often made to feel “lazy” for being unable to lose weight without surgical assistance.  They were also told to return only if they continued to fail (or gain weight).

The Diabetes Pandemic

But as the obesity pandemic continued to escalate at breakneck speed along with obesity-related complications (and healthcare costs skyrocketed), the evidence began to become too overwhelming to ignore.

New guidelines were passed for eligibility criteria for gastric bypass procedures.  These guidelines reduced the necessary BMI to qualify for surgery, especially in patients with co-morbidities such as diabetes.  But it still ignored a large segment of people; non-morbidly overweight people with early diabetes – the very group that was most likely to have a high rate of success and immediate normalization of blood sugars*.

But now the government of the United Kingdom and the National Health Service (NHS) have adopted some of the most progressive recommendations world-wide; aimed at stemming the tide of diabetes and diabetes-related complications such as heart attacks, strokes, renal failure, non-alcoholic fatty liver disease (NASH) and limb ischemia leading to amputation.

The NHS should be commended for their early adoption of eligibility criteria that lowers the BMI requirement to 30 in diabetic individuals and eliminates this requirement entirely in diabetes of Asian descent**. Conservative estimates believe that this change will make an additional one million British citizens eligible for bariatric surgery.

* As a ‘cure’ for diabetes, gastric bypass is most successful in people who have had the disease for less than eight years.

Surge of patients but few surgeries

But can supply keep up with demand?  Last year, according to the our source article (NYT), only 9,000 bariatric procedures were performed in the UK.

**Diabetics of Asian and East Indian  heritage (India, Bangladesh, Pakistan) often develop a more severe, aggressive, rapidly progressive form of diabetes which is independent of BMI or obesity.

This is a page re-post to help some of my new readers become familiarized with Latin American Surgery.com – who I am, and what the website is about..

As my long-time readers know, the site just keeps growing and growing.  Now that we have merged with one of our sister sites, it’s becoming more and more complicated for first time readers to find what they are looking for..

So, start here, for a brief map of the site.  Think of it as Cliff Notes for Latin American surgery. com

Who am I/ what do I do/ and who pays for it

Let’s get down to brass tacks as they say .. Who am I and why should you bother reading another word..

I believe in full disclosure, so here’s my CV.

I think it’s important that this includes financial disclosure. (I am self-funded).

I’m not famous, and that’s a good thing.

Of course, I also think readers should know why I have embarked on this endeavor, which has taken me to Mexico, Colombia, Chile, Bolivia and continues to fuel much of my life.

Reasons to write about medical tourism: a cautionary tale

I also write a bit about my daily life, so that you can get to know me, and because I love to write about everything I see and experience whether surgery-related or the joys of Bogotá on a Sunday afternoon.

What I do and what I write about

I interview doctors to learn more about them.

Some of this is for patient safety: (Is he/she really a doctor?  What training do they have?)

Much of it is professional curiosity/ interest: (Tell me more about this technique you pioneered? / Tell me more about how you get such fantastic results?  or just tell me more about what you do?)

Then I follow them to the operating room to make sure EVERYTHING is the way it is supposed to be.  Is the facility clean?  Does the equipment work?  Is there appropriate personnel?  Do the follow ‘standard operating procedure’ according to international regulations and standards for operating room safety, prevention of infection and  overall good patient care?

I talk about checklists – a lot..

The surgical apgar score

I look at the quality of anesthesia – and apply standardized measures to evaluate it.

Why quality of anesthesia matters

Are your doctors distracted?

Medical information

I also write about new technologies, and treatments as well as emerging research.  There is some patient education on common health conditions (primarily cardiothoracic and diabetes since that’s my background).  Sometimes I talk about the ethics of medicine as well.  I believe strongly in honesty, integrity and transparency and I think these are important values for anyone in healthcare.  I don’t interview or encourage transplant tourism because I think it is intrinsically morally and ethically wrong.  You don’t have to agree, but you won’t find information about how to find a black market kidney here on my site.

What about hospital scores, you ask.. Just look here – or in the quality measures section.

Cultural Content

I also write about the culture, cuisine and the people in the locations I visit.  These posts tend to be more informal, but I think it’s important for people to get to know these parts of Latin America too.  It’s not just the doctors and the hospitals – but a different city, country and culture than many of my readers are used to.

Why should you read this?  well, that’s up to you.. But mainly, because I want you to know that there is someone out there who is doing their best – little by little to try to look out for you.

How the site is organized

See the sidebar! Check the drop-down box.

Information about surgeons is divided into specialty and by location.  So you can look in plastic surgery, or you can jump to the country of interest.  Some of the listings are very brief – when I am working on a book – I just blog about who I saw and where I was, because the in-depth material is covered in the book.

information about countries can be found under country tabs including cultural posts.

Issues and discussions about the medical tourism industry, medical safety and quality are under quality measures

Topics of particular interest like HIPEC have their own section.

I’ve tried to cross-reference as much as possible to make information easy to find.

If you have suggestions, questions or comments, you are always welcome to contact me at k.eckland@gmail.com or by leaving a comment, but please, please – no hate mail or spam.  (Not sure which is worse.)

and yes – I type fast, and often when I am tired so sometimes you will find grammatical errors, typos and misspelled words (despite spell-check) but bear with me.  The information is still correct..

Thank you for coming.

Anthony Bourdain does Colombia

Posted on by

It’s not his first visit – he’s done several other programs highlighting Colombia, but tonight’s episode on his new CNN show, “Parts Unknown” is definitely his best.  It’s the first time I think  he actually ‘got it’ and was really able to convey a real sense of Colombia to his viewers.

While his previous shows were primarily about food, and local food culture – his episodes on Colombian cuisine were always very wide from the mark..  Sure, he had the names of dishes and such – but he didn’t really bring home the feel of Colombia and it’s people.

http://www.youtube.com/watch?v=qNiF0R1QJpk&feature=share&list=SP6XRrncXkMaVZxpButSnMywWvtINMmjXv

Or that Colombian food isn’t really about intense spices, it’s about the intense and rich flavors that comes from the rich textures of the foods themselves – without overpowering curries or heavy sauces..

Better quality, fresher ingredients and a wide variety make for richer flavors

Dr. Marco Sarinana and Dr. Joel Ramos,Bariatric surgeons

Posted on by

Busy day yesterday – spent the morning shift with Jose Luis Barron over at Mexicali General..  Then raced over to Hospital de la Familia for a couple of general and bariatric cases.

The first case was with the ever charming Drs. Horatio Ham, and Rafael Abril (who we’ve talked about before.)  with the always competent Dr. Campa as the anesthesiologist.   (Seriously – Dr. Campa always does an excellent job.)

Then as we prepared to enter the second case – the director of the hospital asked if I would like to meet Dr. Marco Sarinana G. and his partner, Dr. Joel Ramos..  well, of course.. (Dr. Sarinana’s name has a tilde over the first n – but try coaxing that out this antique keyboard..)

So off to the operating room with these three fellows.  (This isn’t my usual protocol for interviewing surgeons, etc. but sometimes it works out this way.)  Their practice is called Mexicali Obesity Solutions.

Dr. Marco Sarinana and Dr. Joel Ramos, Bariatric surgeons

Dr. Alejandro Ballesteros was the anesthesiologist for the case – and everything proceeded nicely.

After that – it was evening, and time to write everything down!

Today should be another great day – heading to IMSS with Dr. Gabriel Ramos for a big case..

Back in the OR with Drs. Ham & Abril, bariatric and general surgeons

Posted on by

My first case this morning with another surgeon was cancelled – which was disappointing, but I still had a great day in the operating room with Dr.  Ham and Dr. Abril.  This time I was able to witness a bariatric surgery, so I could report back to all of you.

Dr. Ham (left) and Dr. Abril

I really enjoy their relaxed but detail oriented style – it makes for a very enjoyable case.  Today they performed a sleeve gastrectomy** so I am able to report – that they (Dr. Ham) oversewed the staple line (quite nicely, I might add).  If you’ve read any of the previous books, then you know that this is an important step to prevent suture line dehiscence leading to leakage of stomach contents into the abdomen (which can cause very serious complications.)  As I said – it’s an important step – but not one that every doctor I’ve witnessed always performed.   So I was a pleased as punch to see that these surgeons are as world-class and upstanding as everything I’d seen already suggested..

** as long time readers know, I am a devoted fan of the Roux-en-Y, but recent literature suggests that the sleeve gastrectomy is equally effective in the treatment of diabetes.. Of course – we’ll be watching the research for more information on this topic of debate. I hope further studies confirm these results since the sleeve gives patients just a little less of a drastic lifestyle change.. (still drastic but not shot glass sized drastic.)

Dr. Ham

They invited me to the show this evening – they are having several clowns (that are doctors, sort of Patch Adams types) on the show to talk about the health benefits of laughter.  Sounds like a lot of fun – but I thought I better catch up on my writing..

I’ll be back in the OR with Los Doctores again tomorrow..

Speaking of which – I wanted to pass along some information on the anesthesiologist for Dr. Molina’s cases since he did such a nice job with the conscious sedation yesterday.  (I’ve only watched him just yesterday – so I will need a few more encounters, but I wanted to mention Dr. Andres Garcia Gutierrez all the same.

the Weight of a Nation: the obesity epidemic

Posted on by

There’s a new series on HBO that is a collaboration between the Institute of Medicine, the CDC and the National Institute of Health (NIH) that begins airing tomorrow night.  This is a huge undertaking that took over three years to bring to the screen.

As many of you know – Obesity, diabetes and bariatric surgery are some of the topics that have been covered fairly extensively here at Cartagena Surgery.  In fact – it’s the heart of Cartagena Surgery – since the very first surgeon interview I ever performed back in 2010 was Dr. Francisco Holguin Rueda, MD, FACS, the renown Colombia bariatric surgeon.  (Shortly after that first leap – came Drs. Barbosa and Gutierrez – which is how we ended up here today.)

I’ve also been spending time, both last week and this week in the company of several bariatric surgeons here in Mexicali. MX and plan to go to several surgeries this week – so it seemed only appropriate to publish a few articles on the topic.

Talking with Dr. Horacio Ham – Bariatric surgeon, part 1

Talking with Dr. Ham, part 2

(I’m still transcribing notes from another one of my recent interviews – with Dr. Jose Durazo Madrid, MD, FACS).

I’d also like to encourage readers to take a look at HBO’s new mini-series (four episodes over Monday and Tuesday).

In the OR with Los Doctores, Dr. Ham & Dr. Abril

Haven’t had time to sit down and write about my trip to the operating room with Dr. Horacio Ham and Dr. Rafael Abril until now, but that’s okay because I am going back again on Saturday for a longer case at a different facility.  Nice surprise to find out that Dr. Octavio Campa was scheduled for anesthesia.  Both Dr. Ham and Dr. Abril told me that Dr. Campa is one their ‘short list’ of three or four preferred anesthesiologists.  That confirms my own impressions and observations and what several other surgeons have told me.

That evening we were at Hispano – Americano which is a private hospital that happens to be located across the street from the private clinic offices of several of the doctors I have interviewed.  It was just a quick short case (like most laparoscopy cases) – but everything went beautifully.

As I’ve said before, Dr. Campa is an excellent anesthesiologist so he doesn’t tolerate any hemodynamic instability, or any of the other conditions that make me concerned about patients during surgery.

Dr. Ham  and Dr. Abril work well together – everything was according to protocols – patient sterilely prepped and draped, etc..

I really enjoy talking with the docs, who are both fluent in English – but I won’t get more of an interview with Dr. Abril until Saturday.

Then – on Wednesday night – I got to see another side of the Doctors Ham & Abril on the set of their radio show, Los Doctores.  They were interviewing the ‘good doctor’ on sympathetectomies for hyperhidrosis – so he invited me to come along.

Los Doctores invited me to participate in the show – but with my Spanish (everyone remembers the ‘pajina’ mispronunciation episode in Bogotá, right?)  I thought it was better if I stay on the sidelines instead of risking offending all of Mexicali..

Los Doctores

on the set of Los Doctores; left to right: Dr. Rafael Abril, Dr. Carlos Ochoa, Dr. Mario Bojorquez and Dr. Horacio Ham

It really wasn’t much like I expected; maybe because all of the doctors know each other pretty well, so it was a lot more relaxed, and fun than I expected.  Dr. Abril is the main host of the show, and he’s definitely got the pattern down; charming, witty and relaxed, but interesting and involved too.. (my Spanish surprises me at times – I understood most of his jokes…)  It’s an audience participation type show – so listeners email / text their questions during the show, which makes it interesting but prevents any break in the format, which is nice.  (Though I suppose a few crazy callers now and then would be entertaining.)

Dr. Ochoa did a great talk about sympathectomy and how life changing it can be for patients after surgery, and took several questions.  After meeting several patients pre and post-operatively for hyperhidrosis, I’d have to say that it’s true.  It’s one of those conditions (excessive palmar and underarm sweating) that you don’t think about if you don’t have – but certainly negatively affects sufferers.  I remember an English speaking patient in Colombia telling me about how embarrassing it was to shake hands -(she was a salesperson) and how offended people would get as she wiped off her hands before doing so.  She also had to wear old-fashioned dress shields so she wouldn’t have big underarm stains all the time..  This was in Bogota (not steamy hot Cartagena), which is known for it’s year-round fall like temperatures and incredibly stylish women so you can imagine a degree of her embarrassment.

It (bilateral sympathectomy) is also one of those procedures that hasn’t really caught on in the USA – I knew a couple people in Flagstaff who told me they had to travel to Houston (or was it Dallas?) to find a surgeon who performed the procedure..  So expect a more detailed article in the future for readers who want to know more.

Tomorrow, (technically later today) I head back to San Luis with the good doctor in the morning to see a couple of patients – then back to the hospital.. and then an interview with a general surgeon.. So it should be an interesting and fun day.

Dr. Horacio Ham, and Los Doctores

Posted on by

Just finished interviewing Dr. Horacio Ham, a bariatric surgeon with the DOCS (Diabetes & Obesity Control Surgery) Center here in Mexicali.  Later this evening, we’ll be heading off to surgery, so I can see what he does first-hand.

Tomorrow sounds like a jam-packed day for the young doctor, he’s being interviewed for a University television series on Obesity in addition to his normal activities (surgery, patients) and of course, the radio show.  Turns out his guest doctor tomorrow evening is none other my professor, the ‘good doctor.’

Sounds like a great show – so if you are interested it’s on 104.9 FM (and has internet streaming) at 8 pm tomorrow night..

I’ll report back on the OR in my next post..

Bariatric surgery and non-alcoholic fatty liver disease

Posted on by

Interesting article over at Medscape on the role of bariatric surgery in the treatment of non-alcoholic fatty liver disease (NAFLD) and (NASH).

For the uninitiated, non-alcoholic fatty liver disease is a serious condition where functional tissue of the liver (used to metabolize and detoxify everything we ingest including medications) is replaced with fat tissue, and eventually fibrosis.  As more and more healthy tissue becomes fatty & fibrotic, the liver function deteriorates until it progresses to cirrhosis and eventual liver failure.

Currently, the only treatment for cirrhosis and liver failure is liver transplantation (which is still only a temporary measure, even in the best case scenarios*.)

But why is the happening?  and who does it affect?  Obesity and obese patients.

To better understand what’s going on – we need to review some basic pathophysiology:

First, lets look at food.  Not in cultural or psychosocial way, or even in food preferences, but food as the body sees it: Fuel for all of our cellular functions.  Just as we run our houses, appliances and cars on different types of fuel – gasoline, natural gas, electricity etc.  our body runs on different types of fuels (proteins, fats, sugars) that all get broken down to serve as energy.  Like fossil fuels – the metabolism of each of these fuels requires different mechanisms (ie. gas-powered versus electric cars) and creates different by-products.

Now I want you to think of a scale.

No, not this kind of scale

No – I want you to think of a scale, as in a delicate balance between differing metabolisms for different fuels.

Think of a multi-tiered scale, where a delicate balance between the types of metabolism and waste products is required for continued good health – anything that upsets the balance such as diabetes – throws everything out of whack.

Normally, as fuel (food) in consumed – the body uses insulin to transport the fuel into the cell for processing (metabolism), so think of insulin as a wheelbarrow carrying in complex carbohydrates (sugars) into the cell.

Now, in a person with obesity & diabetes – two things are occurring – too much fuel and not enough wheelbarrows**.  These means that:

1.  Excess fuel is converted into fat (adipose tissue – which we are all familiar with).

2.  Without the wheelbarrows, the body has to find another way to break down the fuel.  This other pathway – for fat metabolism has a lot of by-products  – namely free fatty acids (cholesterol and triglycerides.)  This leads to numerous problems (hypercholesterolemia and cardiovascular disease for one), and fatty liver disease.

(This is a gross oversimplification of a series of very complex mechanisms, but for today’s discussion – it is sufficient.)

Just as the rates of obesity, and diabesity (diabetes caused by obesity) have skyrocketed, so has cardiovascular disease (which we’ve talked about before) and the prevalence of non-alcoholic liver disease. In fact, the authors of the study below found that 70% of the people with a BMI greater than 35 have some degree of non-alcoholic liver disease, and over 30% have the more severe form – NASH.

The article by Rabl & Campos (2012) looks at the literature on the outcomes (progression or regression of disease) after bariatric surgery in patients previously diagnosed with NAFLD.  (I’ve linked a pdf version of the entire article under the full reference.)

They looked at the current bariatric procedures including the ever popular lap-band procedure and it’s effectiveness in treating NAFLD. What they found was that in the majority of cases – with certain procedures (formal gastric bypass surgery aka Roux en Y, and biliopancreatic diversion procedures) the disease process was not only halted, but regressed as a result of both weight loss, and a reversal of altered metabolism.  They also found that as a result of a reduced stomach surface area (in comparison to lap-band procedures where the stomach remains intact) – reduced ghrelin leads to increased weight loss.

(If you don’t know about ghrelin – think of it as an evil gremlin (the one that makes you want cookies when you know you are about to eat dinner) – since it is a potent appetite stimulant produced by the stomach.  The larger the stomach – the more ghrelin released – so the surgical procedures such as gastric bypass where a portion of the stomach is actually surgical removed are significantly more effective overall that lap-banding procedures.)

This is a significant advancement for medicine and the treatment of obesity related disease – since as we suggested above, multiple authors including Burianesi et. al (2008) suggest that the true prevalence of non-alcoholic fatty liver disease is much higher than we realize, (thus affecting a lot more people.)

Notes

* There is a tendency in American society to ‘gloss over’ many of life’s harsh realities, and no where is this more evidence than in the public perceptions of organ transplantation as a ‘cure’ or permanent solution for organ failure.  Transplanted organs do not have the same life expectancy as native organs (even in the best case scenarios) – and for most people who need non-kidney transplants – they get one opportunity, not multiple.  Transplanted organs last ten years – maybe fifteen at the outside – so this is not a cure (particularly in young patients).  Transplantation also carries a whole host of other problems with it – such as the development of opportunistic infections and cancer from the drugs used to prevent rejection, or rejection itself.  The very drugs used to prevent rejection of some organs may cause failure of others – so relying on transplantation as a ‘cure’ for a disease that is becoming more and more prevalent is a pretty poor strategy.

** This balance between mechanisms can be upset in other ways – by starvation, for example, when the body starts catabolizing proteins..  Catabolizing – think cannibalism – as the body consumes it’s own muscle tissue because there is nothing left for it to eat, after it has exhausted all other sources of fuel.

We knew it would happen…

well, I guess we all knew what was coming next.. There was no way I could really stay still – and not interview some more surgeons while I was down here. So I thought I would start with two more specialities that are near and dear to my heart – and those of my readers; cardiac surgery and bariatric surgery.

I will be talking to Dr. Vasquez – who you may remember from a previous post (during an earlier visit to Mexicali) and Dr. Horatio Ham, a bariatric surgeon who also hosts the radio show, Los Doctores on 104.9 FM.

The Pros & Cons of Bariatric Surgery

Posted on by

As my loyal readers know, I do my best to try to give fair and balanced depictions of surgical procedures, as well as reviews of medical and surgical news and research.  Over at Medscape.com – there is a new video discussion by Dr. Anne Peters, MD.  Dr. Peters is an endocrinologist and a certified diabetic education.  In this video – she talks about the realities of bariatric surgery, and these are things I think that people need to hear.

For more on Bariatric surgery – see my other posts

One of the points that she makes, is (in my opinion) critical.  While bariatric surgery has been shown to cure diabetes in many individuals – there is no medical/ surgical or other treatment to cure much of the pathology related to the development of obesity in the first place.  Obesity is more than poor dietary and exercise habits – it is a psycho-social and cultural phenomenon as well.

For people who don’t want to go to the Medscape site – I have re-posted a transcript of the video from Medscape.com below.

Bariatric Surgery a ‘Magic Bullet’ for Diabetes?

Anne L. Peters, MD, CDE

Transcript
Hi. I’m Dr. Anne Peters from the University of Southern California. Today I’m going to talk about the role of bariatric surgery in the treatment of type 2 diabetes.

There have been a number of recent studies that show just how good bariatric surgery can be for patients with type 2 diabetes.[1,2] In many cases, it seems to cure type 2 diabetes (at least for now), and I think it is an important tool for treating patients with obesity and diabetes.

However, I also have concerns about bariatric surgery, concerns that go back for years as I watched its increased use. When I was a Fellow, I developed a sense of the benefit of extreme caloric restriction for the treatment of type 2 diabetes. I will never forget the first patient I had, an extremely obese man with type 2 diabetes who was on 200 units of insulin per day. His blood sugar levels remained high no matter what we did. He was a significant challenge in terms of management.

One day, he got sick. I don’t remember how or why he got sick, but he ended up in the hospital and I thought that his management would continue to be incredibly difficult. In fact, it was miraculously easy. Within 2 days, he was completely off of insulin and his blood glucose levels remained normal for the entire time he was in the hospital.

This was only a short-lived benefit, however. After he was discharged, he went back to his old habits. He started eating normally, regained the weight, and went back on several hundred units of insulin per day. But it really impressed me how acute severe caloric restriction could, in essence, treat type 2 diabetes.

I have seen many overweight and obese patients with diabetes over the years, and I have seen the frustration as patients go on drugs (such as insulin) that are weight-gain drugs, and they keep gaining more weight. Although I am a big advocate for lifestyle change, many patients can’t do much better. They can’t lose appropriate amounts of weight by their own will or through weight loss programs, or increase their exercise. Therefore, bariatric surgery remains a reasonable option.

For many of my patients who have a body mass index > 35 and type 2 diabetes, I recommend that they at least consider bariatric surgery. Interestingly, very few of my patients actually go for the procedure and I ponder why this is. In part, I think it’s because of the initial evaluation, when you are told what bariatric surgery is like and how much you have to change your habits after the procedure. Before surgery, you are eating however you want to eat and, although you may be trying to diet, there is no enforcement of that diet. After surgery, you have to change how you eat, the portions you eat, and when you eat. I know that people feel fuller, and this is a lot more than just changing one’s anatomy. I think there are significant changes in gut hormones that regulate appetite and satiety. Nonetheless, it is a big change, and many people don’t want to change their habits that much. I know I would be somewhat leery if I were to undergo a surgical procedure that would change my whole way of being. For lots of people, food has many different associations. It’s not just caloric intake; it’s festival, it’s party, it’s joy, it’s sadness. It’s something people like to do, and it hasn’t a lot to do with just maintaining a positive or neutral caloric balance.

I find that people are reluctant to change, and that is understandable. We also don’t know the long-term complications of the procedure. As an endocrinologist, I see 2 things. First, I tend to get sicker patients, so my patients who are on insulin when they undergo bariatric surgery may not get off insulin entirely. They become very disappointed because they think that bariatric surgery will cure them of their diabetes. I also see patients who are too thin, who are nutritionally deficient, who have severe hypoglycemia, or who have significant issues from the surgery itself. In some cases, these patients have needed a takedown of the surgical procedure, restoring them back to their native anatomy.

I think of bariatric surgery as a tool. It is one of many ways to treat our patients with type 2 diabetes. I am a little concerned because we don’t have long-term follow-up data. I think that all bariatric surgery programs, in addition to doing a very thorough preoperative evaluation and counseling, need to do long-term, lifelong follow-up of these patients to see how they do, to see if their obesity returns. In many cases, this does happen. [Patients need to be followed up] to see what happens to their lipids, their blood pressure, and their blood sugar levels over time, and to monitor for other complications.

I think [bariatric surgery] is something that we need to recommend to our patients, and for those in whom it’s appropriate, it is a reasonable step. This has been Dr. Anne Peters for Medscape.

Life after Bariatric Surgery

There is also an excellent article by two nurse practitioners about the long-term interventions and health monitoring needed for wellness promotion and health maintenance after bariatric surgery.  While this article is written for other health care providers – it gives an excellent look at life after bariatric surgery, as well as an overview of the surgical techniques, pre-operative evaluation and anticipated post-operative outcomes.

Gastric bypass to ‘cure’ diabetes goes mainstream

Posted on by

A full year after we reported it here (and several years after initially being reported in the literature), mainstream media has finally picked up the story about gastric bypass surgery for the definitive treatment of diabetes.   The story made all of the heavies; the Washington Post, the Wall Street Journal, and the Los Angeles Times.

Unfortunately, all of these outlets seem unaware of the existing literature in this area – these results while encouraging, are not surprising.  Similar results have been demonstrated in several other (but smaller) studies for the past ten years, which led to previous recommendations (last summer) for the adoption of gastric bypass surgery as a first-line treatment for diabetes in obese patients.

The publication of two new studies showing clear benefits for diabetics undergoing bariatric surgery has brought this news to the forefront.  In both of these studies, diabetic patients were able to stop taking oral glycemics and insulins after surgery within days..

As this front page story from the New York Times notes – these results do not apply to the more widely marketed ‘lap-band.’  This comes to no surprise to dedicated followers at Cartagena Surgery, who have been reading articles on this topic since our site’s inception in late 2010.

You heard it here first.  For more information on this topic, see our tab on Diabetes & Bariatrics under the ‘surgery’ header. We’ve included a small selection from our archives here.

Looks like Panama may bite off more than they can chew..

In a recently published story, the government of Panama is now offering medical  insurance for all tourists to Panama for free.  This insurance is not  ‘Complication Insurance’ which is offered by private surgeons in Colombia and other countries for patients traveling specifically for medical tourism.  Complication insurance covers all possible medical complications resulting from medical procedures at the designated clinic or destination..

No – Panama is taking the European and socialized medicine approach and is offering general medical coverage for ALL short-term travelers to Panama.  (The long-term exclusion is a wise move given the numbers of Americans and other overseas residents who make Panama their retirement home.)  This insurance resembles typical travel policies in that it covers injuries, accidents and other medical situations that may occur while on vacation..  I just hope the Panamanian government hasn’t underestimated its tourists and their injury/ illness potential.

Now readers – don’t get any wild ideas.. This is not the time to stress that ‘trick knee’ while hiking to visit the Naso-Teribes..

Meanwhile, Costa Rica is making a pitch for more corporate clients such as Pepsi-Cola.  These multi-national corporations can potentially bring hundreds of millions of healthcare dollars by diverting their employees to medical tourism destination such as Costa Rica.  (Like Colombia – Costa Rica is an ideal destination for North Americans due to proximity, quality and diversity of services available.)
