Reinforcement Method in Laparoscopic Sleeve Gastrectomy

Staple Line Reinforcement Methods in Laparoscopic Sleeve Gastrectomy: Comparison of Burst Pressures and Leaks

Laparoscopic sleeve gastrectomy is a technically simple popular bariatric operation with acceptable results. Leaks can occur in long staple lines; therefore, variable reinforcement methods are used.

The investigator compared non-reinforced stapling with three staple line reinforcement methods (suturing, absorbable buttressing material and fibrin glue) in laparoscopic sleeve gastrectomy.

The resected stomach specimens were treated in the same manner of reinforcement as used in the surgeries of the corresponding patients and then insufflated until a burst occurred. The burst pressures of the resected stomach specimens and postoperative events of the patients were recorded.

Inclusion Criteria:

• body mass index >40 kg/m2

Exclusion Criteria:

• disruption of the resected stomach during extraction from the abdomen.
