Background: Bariatric surgery is the only treatment for severe obesity recognized as truly effective, and Roux-en-Y gastric bypass is one of the most frequent procedures. The aim of this study is to present a 3D laparoscopic bypass technique with intracorporal anastomosis, performed completely by hand. Methods: After positioning the patient and creating the 20 mL gastric pouch, the gastrojejunal anastomosis is performed with two continuous sutures of resorbable V-Lock 3.0. The same technique is used to do the laterolateral jejunojejunal anastomosis. All patients who have undergone the previously described procedure are included in our bariatric enhanced recovery after surgery (ERAS) protocol. Results: The combination between the by-pass ERAS protocol and the described technique reduces postoperative pain, and usually allows discharge of patients within 48 hours. Conclusions: In our experience, the technique using totally handsewn anastomosis is safe as those previously described in the literature and is cost-effective due to the use of continuous suture for the gastrojejunal and the jejunojejunal anastomoses instead of staplers.
