Staple Line Reinforcement in Laparoscopic SleeveGastrectomy: Experience in 1023 Consecutive Cases

Area of Science:

• Bariatric surgery
• Minimally invasive surgery
• Surgical technique evaluation

Background:

• Laparoscopic sleeve gastrectomy (LSG) is a prevalent bariatric procedure globally.
• Staple line-related complications pose a significant challenge in LSG.
• Effective staple line reinforcement (SLR) is crucial for patient safety.

Purpose of the Study:

• To assess the morbidity associated with LSG.
• To evaluate the efficacy of imbricated oversewing for staple line reinforcement.
• To analyze outcomes at a high-volume bariatric surgery center.

Main Methods:

• Retrospective review of prospectively collected data from January 2010 to September 2016.
• Analysis of 1023 LSG procedures performed by surgeons trained in oversewing technique.
• Data collection included operative time, conversion rates, and early complications.

Main Results:

• A total of 1023 LSGs were performed (67.3% female, mean age 40.6 years, BMI 37 kg/m²).
• Mean operative time was 67.6 minutes; conversion to open surgery rate was 0.3%.
• Early complications occurred in 1.8% of patients (0.5% bleeding); no leaks, stenosis, or mortality were observed.

Conclusions:

• LSG is a safe bariatric procedure when performed with appropriate techniques.
• Imbricated oversewing of the staple line, coupled with surgeon training and optimal setting, effectively reduces complications.
• This study demonstrates zero leaks in a large cohort, supporting the safety of the reinforced staple line.
