Open versus Laparoscopic Roux-en-Y Gastric Bypass: A Comparative Study of Over 25,000 Open Cases and the Major Laparoscopic Bariatric Reported Series

Abstract

The higher cost, higher leak rate, higher rate of small bowel obstruction, and similar long-term weight loss results make the "open" RYGBP our preferred operation. If the incision is taken out of the equation (i.e. use of the LSI), the significant advantages of the open technique become even more obvious.

Benchmarking Best Practices in Weight Loss Surgery

“…Conversely, open RYGB costs less, causes fewer internal hernias, and reduces reoperation rates from 4% to 1% [49]. Open RYGB also reduces leak and stenosis rates despite operations in higher- risk patients [29]. …”

Dental manifestations in bariatric patients: review of literature

“…Another option is Gastric bypass Roux-in-Y technique, in which a small pouch is created (15 to 30 mL) stapling the stomach itself, restricting the amount of food that can be consumed. A part of the small intestine is diverted, delaying the mixing of food with gastric juice 15 . Finally, Misuse Biliopancreatic is performed in a way that ¾ of the stomach are removed and the intestine is shortened, reducing the time of contact of food with the intestine, considerably reducing the absorption of the nutrients 22 .…”

Results of Completion Gastrectomies in 44 Patients with Postsurgical Gastric Atony

“…Reported leak rates in the literature are between 2% and 9% for esophagojejunostomy after total gastrectomy, 23-25 versus the standard leak rate of less than one percent reported in recent bariatric literature after a standard Roux-en-Y gastric bypass. 26,27 Furthermore, all four of our patients who had postoperative anastomotic strictures requiring dilatation had undergone a total resection with esophagojejunostomy. In some patients, leaving even a small gastric remnant is impossible, due to the nature of the previous operations, adhesions, and distortion at the gastroesophageal junction.…”
