Abstract

Background

Conversion of Roux-en-Y gastric bypass (RYGB) to single anastomosis duodenal switch can be a complicated and time-consuming operation for surgeons.

Purpose

The purpose of this article is to present our technique of single-step laparoscopic conversion of RYGB to single anastomosis duodenal switch bilio-pancreatic diversion and vertical sleeve gastrectomy, creating a 250-cm common channel.

Material and Methods

A laparoscopic technique was utilized in the conversion.

Results

After the gastrojejunostomy is completely separated from the gastric remnant, a sleeve gastrectomy was created followed by duodeno-ileal anastomosis.

Conclusion

Conversion of RYGB to single anastomosis duodenal switch can be a complicated operation, requiring a two-stage approach in most cases. With the adoption of the described technique, it can be easier to be achieved in a single-stage.
