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.
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.

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]
