Reinforcing the staple line during laparoscopic sleeve gastrectomy: prospective randomized clinical study comparing...

Area of Science:

• Bariatric Surgery
• Minimally Invasive Procedures
• Surgical Complication Reduction

Background:

• Laparoscopic sleeve gastrectomy (LSG) presents challenges with gastric leak and hemorrhage.
• Staple line reinforcement techniques, including absorbable sutures or Gore Seamguard, aim to mitigate these complications.
• Limited randomized data exists on the efficacy of staple line reinforcement in LSG.

Purpose of the Study:

• To compare three staple line management techniques during LSG: no reinforcement, Gore Seamguard buttressing, and staple line suturing.
• To evaluate the impact of these techniques on operative time, blood loss, and postoperative complications.
• To provide evidence-based guidance for LSG staple line management.

Main Methods:

• A prospective, randomized study involving 75 patients undergoing LSG.
• Patients were divided into three groups based on staple line management: no reinforcement (group 1), Gore Seamguard (group 2), and suturing (group 3).
• Key outcomes including operative time, blood loss, and postoperative leaks were prospectively recorded and compared.

Main Results:

• Gore Seamguard buttressing significantly reduced blood loss during stomach sectioning (3.6 mL vs. 19.5 mL) and overall (32.5 mL vs. 48.9 mL) compared to no reinforcement.
• No staple line reinforcement resulted in shorter mean operative times for stomach sectioning (15.9 min vs. 20.8 min) and total procedure time (47.4 min vs. 48.9 min).
• No statistically significant difference in postoperative leak rates was observed among the three techniques.

Conclusions:

• Gore Seamguard buttressing is effective in reducing blood loss during LSG.
• Omitting staple line reinforcement in LSG can lead to decreased operative time.
• The choice of staple line management technique does not significantly impact the risk of postoperative leaks in LSG.
