Brief Summary

Obesity has become an important medical and social problem in western countries today. Roux-en-Y gastric bypass (LRYGB) is the most commonly performed surgery for the treatment of morbid obesity in the United States. Recently, there has been a steady increase in the number of surgeons performing bariatric surgery. In 2008, approximately 344,000 bariatric procedures were performed worldwide, of which 220,000 were performed in the United States and Canada. Most of these surgeries were laparoscopic gastric bypass procedures. There are many technical variations in the performance of the Roux-en-Y gastric bypass, especially when the approach is laparoscopic. Three techniques are commonly used when creating a gastrojejunostomy (GJ): hand-sewn, linear-staple, and circular-staple approaches. The effect of larger-caliber gastrojejunostomy on long-term weight loss is worrisome. Numerous recent reports describe the relationship between gastrojejunostomy enlargement and weight gain after gastric bypass, suggesting that this is a potentially valid concern. In this study, we aim to determine the effect of this potential GJ enlargement on weight loss.

Masking Details
The surgeon who will perform the endoscopy after the Roux nY gastric bypass will not know the preoperative body measurements of the patient and the post-operative weight loss, and the patient who has undergone endoscopy will not know the diameter of the gastrojejunostomy anastomosis. Only the person collecting the data of the study will be able to see these results.
Purpose
DIAGNOSTIC
Intervention Model
SINGLE GROUP
Model Details: All patients undergoing Roux nY gastric bypass will have their anastomotic diameter measured by performing an upper gastrointestinal endoscopy postoperatively. The effect of anastomosis diameter on weight loss will be investigated. All patients will be compared by recording their %EWL, height, weight and BMI values during endoscopy.
