Review of Our Experience Using Modified Staple Line Suturing Technique in Laparoscopic Sleeve Gastrectomy

Area of Science:

• Bariatric Surgery
• Minimally Invasive Surgery
• Gastrointestinal Surgery

Background:

• Laparoscopic sleeve gastrectomy (LSG) is a prevalent bariatric procedure.
• LSG carries risks of serious complications, including staple line leakage, bleeding, and stenosis.
• The effectiveness of various staple line reinforcement methods is debated.

Purpose of the Study:

• To evaluate the outcomes and safety of a modified staple line suturing technique (purse-string + oversewing) in patients undergoing LSG.
• To assess the efficacy of this technique in reducing postoperative complications.
• To provide data on the safety profile of this specific LSG reinforcement method.

Main Methods:

• Retrospective analysis of 505 patients who underwent LSG with modified staple line suturing between March 2018 and February 2021.
• Data collected included patient demographics, operative details, and 30-day perioperative and postoperative complications.
• Analysis focused on complications such as leaks, bleeding, stenosis, and other adverse events.

Main Results:

• No instances of staple line leak, stenosis, or mortality were observed in 505 patients.
• Minor operative complications included hepatic injury (1.6%) and anesthesia awareness (0.6%).
• Postoperative complications were low, with bleeding (0.4%), portomesenteric vein thrombosis (0.2%), and wound infection (0.6%).

Conclusions:

• The modified purse-string and oversewing staple line technique for LSG is effective.
• This method can be safely implemented with a low rate of morbidity.
• The technique demonstrates a favorable safety profile for LSG procedures.
