The gastrojejunostomy in laparoscopic Roux-en-Y gastric bypass

Area of Science:

• Bariatric Surgery
• Surgical Techniques
• Gastrointestinal Surgery

Background:

• Laparoscopic gastric bypass is a common bariatric procedure for obesity.
• Creating the gastrojejunal anastomosis is a critical step in gastric bypass surgery.
• Various techniques exist for gastrojejunal anastomosis, impacting surgical outcomes.

Purpose of the Study:

• To describe and compare different techniques for gastrojejunal anastomosis in laparoscopic gastric bypass.
• To evaluate the advantages and disadvantages of stapled versus handsewn anastomoses.
• To discuss the authors' experience with these surgical methods.

Main Methods:

• Review of established techniques for gastrojejunal anastomosis.
• Description of circular stapler techniques (21-mm and 25-mm anvil).
• Description of linear stapler techniques.
• Description of handsewn anastomosis techniques.
• Discussion based on the authors' clinical experience.

Main Results:

• Stapled anastomoses include circular and linear techniques.
• Handsewn anastomosis is increasingly utilized.
• Handsewn techniques may offer advantages over mechanical stapling.
• The study provides a comparative overview of these methods.

Conclusions:

• Multiple techniques for gastrojejunal anastomosis in laparoscopic gastric bypass are available.
• Handsewn anastomosis is a viable and increasingly frequent alternative to stapled methods.
• The choice of technique should consider potential advantages and surgeon experience.
