Summary
Routine intraoperative endoscopy (IOE) use in laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery significantly reduces leak and stenosis complications. This study found IOE to be a valuable tool for improving patient outcomes in LRYGB procedures.
Area of Science:
- Bariatric Surgery
- Minimally Invasive Surgery
- Surgical Complications
Background:
- Leak and stenosis are significant morbidities following laparoscopic Roux-en-Y gastric bypass (LRYGB).
- Evaluating the impact of routine intraoperative endoscopy (IOE) on reducing these complications is crucial.
Purpose of the Study:
- To assess the efficacy of routine intraoperative endoscopy (IOE) in minimizing leak and stenosis rates after laparoscopic Roux-en-Y gastric bypass (LRYGB).
Main Methods:
- A review of 342 LRYGB cases performed between 2009 and 2014.
- Routine intraoperative endoscopy (IOE) was performed in all cases, with re-intervention for positive leak tests.
Main Results:
- The clinical leak rate was 0.88% and stenosis rate was 0.88% in LRYGB.
- Intraoperative endoscopy (IOE) demonstrated a 75% positive predictive value and 99.5% negative predictive value for detecting leaks.
- Re-intervention based on IOE findings successfully resolved leaks in 83% of identified cases.
Conclusions:
- Routine intraoperative endoscopy (IOE) adoption has influenced operative strategy.
- The use of IOE is associated with low leak and stenosis rates in laparoscopic Roux-en-Y gastric bypass (LRYGB).

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

6.6K
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.
