Standard Common Channel In Duodenal Switch Will Result In Weight Regain.

December 16, 2016 1:57 pm

Stéfane Lebel, M.D.*, Geneviève Dion, M.D., Simon Marceau, M.D., Simon Biron, M.D., M.Sc., Maud Robert, M.D., Laurent Biertho, M.D. earlier this year released a research article comparing patients undergoing standard common channel of 100cm and standard common channel 200cm. The conclusion of this article was: “In this population, BPD-DS with a 200-cm common channel offered similar remission rate of co-morbidities compared with standard BPD-DS. It was associated with similar weight loss at nadir, followed by a more significant weight regain. It might yield a lower rate of nutritional complications. Long-term randomized data are needed to detect other potential advantages.”

Our Experience:

One of the most dreaded outcomes of any weight loss surgical procedure is weight regain. This is assuming that initial adequate weight was lost to result in resolution of the co-morbidities in the first place.  As the weight loss surgical field has changed over the years so has been the cases of regain that we have seen.

There was a time when Lap bands were being revised for inadequate weight loss and weight regain. Not to mention the complications of reflux, difficulty swallowing and persistent Nausea and vomiting. Then as more Gastric bypass procedures “aged” the number of patients that started looking for revision for weight regain increased. The latest fad is the Vertical Sleeve Gastrectomy that are done with false sense of expectation and results. The long term outcome of Vertical Sleeve Gastrectomy is no where close to that of the Duodenal Switch, independent of the size of the sleeve. In fact, more surgeons are trying to get a little more weight loss by making the sleeve too tight. All they are doing is creating a significant and debilitating set of problems such as reflux, nausea, and solid intolerance.

The ideal revisional procedure for these patients should be the Duodenal Switch. Some surgeons, however, have started advocating “single anastomosis” knock off the duodenal switch. Others do “standard length common channel” rather than a Hess method Duodenal Switch. I have always performed a traditional Hess method Duodenal Switch.  The Hess method Duodenal Switch has held the largest and longest excess weight loss maintenance for 28 years, going into 29 years.  Here is a past blog regarding small bowel length.

Duodenal Switch

August 24, 2016 5:45 am

Buyer Beware ! There are a lot of look alike and counterfeit “Duodenal Switch” procedure being performed. A recent online chat discussion clearly demonstrates the point that just because a patient is told that they had the duodenal switch operation this is not necessarily the case.

In our practice, we always warn our patients of not comparing notes and their outcome to others. I perform the Duodenal Switch procedure  the way it was described by Dr. Hess, making the common and alimentary lengths as a percentage of the total length of small bowel. This is why our patient population has very little nutritional, and gastrointestinal issues compared to others. Unfortunately when a patient is given a disproportionately long Common channel and/or Alimentary channel the patient will have inadequate weight loss. Alternatively, when patients are  given a shorter alimentary channel in proportion to the total bowel length, significant nutritional deficiencies can arise. In a shorter alimentary channel situation patients have to consume higher doses of vitamins and nutrients to keep their laboratory values normal.

I have repeatedly raised the issues to clearly distinguish the single anastomosis procedures from Duodenal Switch operation.

One of the unfortunate problems is the lack of clear guidance given to the patients. It is not uncommon, when I do second opinion consultation with patient who were given generic gastric bypass post op protocol and instructions after their duodenal switch operation. This clearly shows lack of fundamental understanding of the practice performing these procedures and it is carried onto the patient.

Don’t lose your Pyloric Valve over a Failed Gastric Sleeve

June 22, 2016 9:32 am

In my opinion, there are very few reasons to lose your Pyloric Valve after sleeve gastrectomy. Recently, I am hearing of people who have had regain due to a failed Sleeve Gastrectomy being revised to Gastric Bypass RNY and then seeking a Duodenal Switch due to regain from Gastric Bypass RNY. A better option is to go from Sleeve Gastrectomy to Duodenal Switch, due to the long term excess weight loss maintenance of Duodenal Switch. The benefit of the pyloric valve can not be taken lightly.

Let’s start by reminding ourselves as to how the Sleeve Gastrectomy has gained popularity. In the quest for a simple solution to the complex problem of obesity, adjustable gastric banding gained popularity only fail to deliver anything close with the results that were promoted and heavily marketed. The focus was then changed to another seemingly simple procedure, laparoscopic sleeve gastrectomy. For some surgeons this is a new procedure. Surgeons that had been doing the duodenal switch operation for decades, sleeve gastrectomy has not been a new procedure. Surgeons that just started doing sleeve gastrectomy as a stand alone procedure started experiencing complications of the sleeve gastrectomy, such as regain and are now looking for another option for these patients. This complication are even more frequent when they’re done following a failed adjustable gastric band procedures due to the metabolic issues after revising one weight loss surgery to another. A similar short sighted approach is also being promoted with SIPS/SADI procedures, which is significantly simpler to perform than the duodenal switch operation.

Laparoscopic sleeve gastrectomy has a predictable profile for weight loss. It will not have as good on the long-term success rate as a duodenal switch operation. Complications of the sleeve gastrectomy including reflux, stricture, fistula, inadequate weight loss which may warrant evaluation and possible intervention. In my opinion, as a surgeon who does the duodenal switch operation routinely, a sleeve gastrectomy requiring revision should almost never be revised to a gastric bypass. I have seen number of patient’s who have had an adjustable gastric banding which was revised to the sleeve gastrectomy then to a gastric bypass. We are contacted for a possible revision to Duodenal Switch operation because of the weight regain. One can argue that the patient should not have had the sleeve gastrectomy or gastric bypass. It is critical that the complexity of the disease of the obesity is clearly appreciated that it purely restrictive procedure will not yield the desirable outcome long-term.

Benefits of the Pyloric Valve:

The pylorus is the valve located at the end of the stomach. It controls the release of the liquid mixture of food from the stomach into the small intestine.

The body naturally regulates the passage of food, so food will stay in the stomach for a certain period of time. We believe it is very important to continue that feeling of fullness in between meals. As a result, one of the principle functions of the pyloric valve is to regulate the amount of food products released into the small intestine where they are absorbed. This helps prevent dumping syndrome and ulceration.

The bodies natural diameter of stomach, pyloric valve and small intestine is left intact. This elevates stretching of the stomas created by RNY Gastric Bypass.

Summary

These failed Sleeve Gastrectomies should be revised to Duodenal Switch unless there are overwhelming health issues that would require another option. I always suggest several opinions from different Bariatric Surgeon’s who do a variety of Weight Loss Surgeries before deciding which type of revision to proceed with.

Is Weight Loss Important Before Weight loss Surgery?

June 21, 2016 7:52 am

The question of “Is a pre operative diet and weight loss important?” No. This is the short answer. In a previous blog, “Weight Loss Before Weight Loss Surgery?” I have gone into further detail about why I don’t require a pre operative diet and weight loss program.

More recently there has been a concerted effort by a number of major health plans to require 3-6 months documented pre operative diet attempt prior to authorization for weight loss surgery. Furthermore, there are surgeons who would mandate a 10% weight loss as a precondition for the patient to have a weight loss surgery, laparoscopic sleeve gastrectomy for example. The overwhelming scientific literature fails to support any direct correlation between preoperative weight loss and the outcome of the weight loss surgery.

Some surgeons require preoperative weight loss as a way to reduce the size of the liver. I’ve personally have never met a liver I couldn’t work around unless it was severely diseased.

Diagram of liver and adjacent organs.
Diagram of liver and adjacent organs.

There is some literature to support this position. However, one has to critically look at all the studies. Almost all the studies have very specific population and procedures that are being looked at. Most often the recommendations had been made for adjustable gastric banding procedures. There are also some that are recommending the same for Lap Sleeve cases only siting the reduction of the liver size as a reason for the Very Low Energy Diet as a precondition to surgery. It is, however, important to remind ourselves that there is no long term studies whatsoever that show any relationship between the preoperative weight loss and the outcome of any weight loss surgery.

Shared Success Story Update- Cyndi RNY to Duodenal Switch

Three Years Out Cyndi E … RNY to Duodenal Switch Revision

The Journey to get to the three year mark, has been amazing! And truly, The JOY is in the JOURNEY.

I am a JOYFUL “Third Time’s the Charm Revisionista”…. This is my new title…. And I say this proudly!!

For too many years (like 45! at least) I carried the shame and blame of being overweight and beat myself up on the inside. I tried everything, from age 13. I tried every diet, every program, and yes, I will say it, I have had THREE, yes THREE surgeries. And then, I let others convince me, and I bought into this, that I was a failure… BUT, I am not a failure. Surgery fails. For a long time, I could not say that, again with the SHAME word. BUT, I am done with shame, and I am done with blame. I no longer blame myself and I no longer shame myself or my body, because now, she and I, my body and I, are friends, and we are nice to each other.

Thankfully for me, I was in the right place at the right time, and met Dr. Ara Keshishian… My story with Dr. Keshishian, is simple. Dr. K was the first Doctor that did not blame me for my weight. He explained that each weight loss surgery has different measures of success, and percentages by weight loss surgery and outcomes. He educated me. He did not blame or shame me, he encouraged me. He also did an Endoscopy and found that I has a Gastro-Gastric Fistula. Simply put, this was an abnormal connection between the bypassed stomach and the small pouch created by the RNY Gastric Bypass surgery. Food could travel two ways, thus rendering the Gastric Bypass ineffective causing weight gain.

Dr. Keshishian performed my revision from RNY to Duodenal Switch on May 31, 2013. The procedure corrected my anatomy, enabling me to lose weight and regain my health. I have no complications, no issues post surgery.

Today, being a “Three Year Old” RNY to Duodenal Switch revisionista, I have a better perspective as a relative “newbie”. I am not a prisoner of my weight. I have lost 125-130 pounds, I am 5’12” (6 feet lol) 61 years old and for the first time in my life at a NORMAL WEIGHT! I do not fear, any longer, that I will gain my weight back. I am, however, mindful that I am consistent in my new habits and patterns that I have put in place, that keep me on track. I am also accountable. To myself, also to my Weight Loss Support Group, here in Paso Robles, to some fellow DS girlfriends that

I talk with about challenges, and with Dr. Keshishian. I am not held captive by my limitations, or my weight, and now I live with the possibilities each day brings and the fun challenges I put in front of me to conquer.

To the “newbies” I say, please take your time, treat yourself kindly, with your inner voice. This is not a race, this is a journey. Don’t rush, it’s ok to take it slow, listen to your body. And do not compare your journey to anyone else. You are you! You do you! You can do this well, one day at a time. Listen to the sage advice of those who went before you. We too have learned by trial and error. Be willing to sacrifice in the short term, for the gift of the long term life. Your DS is forgiving, you be forgiving as well!!!

Remember: WATER, PROTEIN, SUPPLEMENTS, EVERYTHING ELSE, EAT CLOSE TO THE DIRT, ELMO DIET

With JOY, Cyndi

Inadequate Weight loss and Weight Regain

May 24, 2016 7:56 am

There were numerous causes for the inadequate weight loss and or weight regain after weight loss surgery.

These factors may include:
1-Type of the surgery: Duodenal Switch, RNY, Adjustable Gastric Banding, Intragastric Balloon, etc.
2-Patients metabolic state (age, activity level, hormones state etc)
3-Co-morbidities
4-Patient compliance
5-Other

Each and every one of these may be an independent factor or may be a contributing cause.

In our experience, patients non-compliance is not as common as others believe. Frequently, we see patients in our office where they have been told that the poor outcome of the surgery is “their fault”
We see this with RNY, and Band patients as well as some of the duodenal switch patients who are seeking advice for weight regain or inadequate weight loss.

I would like to talk about the issues of inadequate weight loss or regain post Duodenal Switch specifically. Duodenal switch operation as described by Dr. Hess, outlined the division of the small bowel lengths to be proportional to each and every patients own total bowel lengths. This meant that two patients with the same BMI and weight will end up with two different lengths for common and alimentary limbs if there total length of the bowel is different. Unfortunately, too often patients are given a “standard”  or “set” ( not clear what that word means, since there is no established standard in the literature) length for common channels and alimentary  channels regardless of the total small bowel length. In some patients, those lengths may result in acceptable weight loss. However, quite frequently a patient with a preselected length for the common and alimentary limbs will end up either loosing too much weight and have nutritional problems or not loose adequate weight. As with all practices, we have over the years had patients who have had nutritional deficiencies and excessive weight loss or have had inadequate weight loss. Looking at the raw numbers however, we have had more patient from other practices that have come to us for revisions and corrections of lengths of the bowel lengths from other practices that our own patients have required.

Another level of the confusion is the improper interchanging of the “SIPS and SADI” procedures with the duodenal switch operation. As I have said in the past repeatedly, SIPS and SAID are not the same as the duodenal switch- and attempt to call these different procedures the same is misleading to say the least.

The other category of weight regain or inadequate weight loss includes medications and new health issues.  Discussed in a previous blog, there are many medications that can influence weight gain.  It is important to work with your health care provider to find medications that have a positive effect on symptoms without added side effects whenever possible.

In summary, weight re-gain or inadequate weight loss can have many facets.  However, surgical technique can provide an advantage.  Each aspect should be addressed and identified.
