Summary of "Intraoperative Endoscopic Assessment of the Pouch and Anastomosis During Laparoscopic Roux-en-Y Gastric Bypass."

As an advanced surgical procedure, laparoscopic Roux-en-Y gastric bypass (LRYGB) is associated with considerable morbidity, especially in the learning curve period. The aim of this study was to evaluate the role of endoscopy during LRYGB surgery in assessing the gastric pouch and anastomosis for air leak, bleeding, and structure at the beginning of a bariatric surgery program. Patients who underwent LRYGB for morbid obesity between May 2008 and May 2009 were included in this study. After the completion of the anastomosis, an endoscopic examination was carried out. The transection line and anastomosis site were examined for bleeding and patency and inspected for air leak under laparoscopic vision. Thirteen morbidly obese patients (mean body mass index, 48.0 ± 6.8 kg/m(2)) were evaluated by endoscopic examination during the LRYGB operation. None of the cases had bleeding at the transection line or anastomosis site. In two patients, air leak test was positive and the anastomosis was reinforced with additional sutures. All the patients, including those with positive air leak test, were discharged from the hospital with no leak complications. After a mean follow-up of 9.1 ± 5.5 months, except for the patient who underwent balloon dilatation, no other patient had anastomotic stricture. Intraoperative endoscopy is invaluable in the assessment of bleeding, anastomotic patency, and air leak during LRYGB, and it might be a helpful auxiliary tool to decrease morbidity during the learning curve period. Also, it helps solve intraoperative problems during the surgery so that postoperative complications might be prevented.

Medical and Biotech [MESH] Definitions

A Y-shaped surgical anastomosis of any part of the digestive system which includes the small intestine as the eventual drainage site.

Endoscopic instruments used for viewing the rectovaginal pouch and pelvic viscera.

Fiberoptic endoscopy designed for duodenal observation and cannulation of VATER'S AMPULLA, in order to visualize the pancreatic and biliary duct system by retrograde injection of contrast media. Endoscopic (Vater) papillotomy (SPHINCTEROTOMY, ENDOSCOPIC) may be performed during this procedure.

A vessel that directly interconnects an artery and a vein, and that acts as a shunt to bypass the capillary bed. Not to be confused with surgical anastomosis, nor with arteriovenous fistula.

Surgical procedure in which the STOMACH is transected high on the body. The resulting small proximal gastric pouch is joined to any parts of the SMALL INTESTINE by an end-to-side SURGICAL ANASTOMOSIS, depending on the amounts of intestinal surface being bypasses. This procedure is used frequently in the treatment of MORBID OBESITY by limiting the size of functional STOMACH, food intake, and food absorption.
