[The staple line in sleeve gastrectomy]

Area of Science:

• Bariatric Surgery
• Minimally Invasive Surgery
• Surgical Complications

Background:

• Postoperative complications, including staple line leak and bleeding, are significant risks following laparoscopic sleeve gastrectomy.
• Effective strategies to mitigate these early complications are crucial for patient safety and outcomes.

Purpose of the Study:

• To evaluate the effectiveness of oversewing the staple line in reducing postoperative leak and bleeding after laparoscopic sleeve gastrectomy.
• To compare outcomes between selective and mandatory staple line oversewing techniques.

Main Methods:

• A retrospective-prospective, non-randomized trial involving 638 patients undergoing laparoscopic sleeve gastrectomy.
• Patients were divided into two groups: selective staple line oversewing (n=297) and mandatory staple line oversewing (n=341).
• Postoperative complications, specifically leak and bleeding, were meticulously recorded and compared between the groups.

Main Results:

• No significant difference in the rate of postoperative leak was observed between the selective (0.30%) and mandatory (0.29%) oversewing groups (p = 0.9203).
• Postoperative bleeding occurred in 2.7% of patients with selective oversewing versus 0% in the mandatory oversewing group, a statistically significant difference (p = 0.0023).

Conclusions:

• Oversewing the staple line does not appear to influence the incidence of postoperative leaks after laparoscopic sleeve gastrectomy.
• Mandatory oversewing of the staple line is associated with a statistically significant reduction in postoperative bleeding complications.
