Minimizing Omental Bleeding Risk Following Sleeve Gastrectomy: Assessing the Double-line Sealing Technique

Area of Science:

• Bariatric Surgery
• Minimally Invasive Procedures
• Surgical Hemorrhage Control

Background:

• Laparoscopic sleeve gastrectomy (LSG) is a leading bariatric procedure, but postoperative bleeding remains a concern.
• Standard stapler reinforcement may be insufficient in obese patients with significant omental fat.
• Existing sealing devices may have limitations in managing bleeding from omental tissue.

Purpose of the Study:

• To evaluate a novel double-line sealing (DLS) technique for omental dissection during LSG.
• To assess the efficacy of DLS in reducing postoperative bleeding complications.
• To compare DLS outcomes with standard dissection methods in LSG.

Main Methods:

• Retrospective analysis comparing 222 patients undergoing LSG with DLS versus 297 patients with standard dissection.
• DLS technique involves applying two adjacent seals on the omentum.
• Outcomes assessed include severe intraperitoneal bleeding, reoperation rates, operative time, and hospital stay.

Main Results:

• The DLS group showed a significantly lower incidence of severe intraperitoneal bleeding (0.45% vs. 3%).
• Reoperation rates were significantly reduced in the DLS group (0% vs. 0.67%).
• DLS correlated with a reduced length of hospital stay but increased operative time.

Conclusions:

• The double-line sealing technique demonstrates potential for reducing severe postoperative bleeding in LSG.
• This technique appears to decrease the need for reoperations following bariatric surgery.
• Larger studies are recommended to confirm the efficacy and safety of DLS in LSG.
