Revision or Reversal of the Duodenal Switch

September 08, 2012 7:00 pm

A significant portion of my practice involves the revision of the Gastric bypass and Adjustable Gastric Banding procedures to the Duodenal Switch operation. The re-operations are necessary to correct the complications that have been caused by these procedures. There are also instances of required revisions due to inadequate weight loss or weight regain. Our website contains detailed information regarding reasons for revision and the reversal of weight loss surgical procedures. I think it is important to mention that these complications are very common and almost never have anything to do with the patient’s behavior.

Duodenal switch operations may also require reversal or revision. The general reasons for a revision or reversal of the Duodenal Switch is the same as for all weight loss surgical procedures and include a variety of reasons. The reversal or revision of the Duodenal Switch operation is one of the simplest revision surgeries that I perform.

Let’s review a few facts about Duodenal switch.

Reversal of Duodenal Switch
Duodenal Switch anatomy

The Duodenal Switch procedures has two components:

1.) The sleeve gastrectomy

2.) The separation of the biliopancreatic secretions from the food to limit its absorptions.

Clearly, the portion of the stomach that has been removed cannot be reintroduced to the abdominal cavity. The second part of the operation can, however, be easily “undone.

The assumption is that the bowel needs to be divided again and re-anastomosed to reconstitute its continuity. This revision or reversal of the Duodenal Switch operation is done by simply creating a new connection between a new anastomosis, located between the biliopancreatic limb, and the alimentary limb.

If a complete reversal is needed, then the connection is made just distal to the ligament of Treitz. Ligament of Treitz is the transition point between the duodenum and Jejunum. This single anastomosis is safe and simple to perform and does not involve removing the previous staple lines.

If a partial revision is needed, or the common channel needs to be lengthened, then the anastomosis is made further proximal to the junction of both the alimentary limb and the biliopancreatic limb, but distal to the ligament of Treitz to allow for increased absorption of the calories and nutrientsIn my opinion, the revision and reversal of the Duodenal Switch operation is, from a technical perspective, the simplest of all revisional weight loss surgical procedures.

Obesityhelp.com revision Forum information

I am not sure what has happened over the past two weeks or so, but I have received a number of inquiries from patients who have had questions about the revision of RNY or Lap Band® for weight regain, inadequate weight loss, or other complications. I finally had to ask one of the patients where he got his information and heard about our practice. His source of information was the obesityhelp.com website.

I have spent some time looking over and responding to several postings on the forum sites. I have referred to a number of publications in some of my postings on obsityhelp.com.

Nishie et.al. (Obesity Surgery, 17, 2007 1183-1188) reported:
“Pouch size area, measured by routine UGI on the first postoperative day does not influence short term postoperative weight loss. “

Cottam et.al. (Obesity Surgery 2009, 19:13-17) concluded:
“The level of restriction or the presence of stenosis achieved by different stapler sizes does not have a significant role in weight loss.”

O’Connor et.al. (Surgery for Obesity and Related Dis. 4(2008) 399-403) summarizes:
“With construction of divided, vertical, lesser curvature based small-volume (less than or equal to  20 cm gastric pouches, the actual size of the gastric pouch did not correlate with the %EWL at 1 year laparoscopic GB.”

I am a firm believer that the best patient is the most knowledgeable patient. It is always safer to spend as much time as needed to ask questions and investigate all options. If I can provide any information, please contact us at [email protected]

Get informed

As a surgeon, one of my duties is to discuss Informed Consent. There are two components to this, one of which is the consent part. This is where the discussion of risks, benefits, and complications takes place. It is also where options are discussed. A patient cannot give consent if he or she is not informed, which is the second component. The patient should only grant his or her consent if provided with details and every available option.
In my clinical practice, I routinely discuss all the surgical options with a prospective patient. It is my duty to explain in great detail what the surgical alternatives are, what their relative risks are when compared to each other, and the pros and cons of each procedure. Once this information is presented, I would then discuss the rationale as to why certain procedures are superior in certain clinical conditions. It is ultimately the patient who makes the decision as to which procedure is right for the treatment of morbid obesity. In some cases, however, if I do not believe that the procedure the patient has decided on will serve the patient’s long or short-term health needs, I will ask that the patient seek another surgeon.  One of the most common examples of this situation is when patients are seen in my office for surgical treatment of morbid obesity and inquire about the Lap Band®. They have seen an advertisement on television, radio, or even on a billboard. There are even those patients that are told by the primary care physicians that they should ONLY have the Lap Band® done because it will solve all of their problems. The promotional marketing material is only a small portion of a large body of information that is made available to patients and their primary care physicians. To most patients, Adjustable Gastric Banding (Lap Band®, Realize Band®) are “drive-thru” procedures.  They have been advertised as a procedure in which a patient goes to a surgeon’s office, gets examined, operated on, loses weight, and lives happily ever after. This is untrue on a number of fronts and far from the way it actually works for the overwhelming number of patients that get the Lap Band® done. I am not against the adjustable gastric banding procedures. I only advocate that the expectations be set for the patients on an appropriate level.  First of all, the Lap Band® is not for everyone. The scientific information on this matter is overwhelming. The educational booklet that is available and published by Allergan (the manufacturer of the band) has a list of conditions in which the band should not be used. Then there is the relative efficacy of the banding procedure compared to the Duodenal Switch and the Gastric Bypass operation. The questions a patient and a primary care physician should ask:
Are the treatment options effective in both treating and resolving the specified conditions of each patient? 
What are the chances that a patient suffering from diabetes, high cholesterol, or high blood pressure will be cured of these conditions if they have the Gastric bypass, Duodenal Switch, or the Lap Band done. 
The reality is that, in my opinion, most patients opting for the Lap Band procedure have not been educated and provided with the information necessary to make an informed decision. When you consider how little most patients will lose with the Lap Band, one has to realize that the risks, as little as they may be compared to other procedures, are not worth taking.
