    Abstract:
    BACKGROUND AND OBJECTIVES: Laparoscopic sleeve gastrectomy is a technically simple and popular bariatric operation with acceptable results. However, leaks can occur in long staple lines, for which various reinforcement methods are used. We compared nonreinforced stapling in laparoscopic sleeve gastrectomy with 3 staple line reinforcement methods: suturing, absorbable buttressing material, and fibrin glue. METHODS: From March 1 until September 30, 2014, 118 patients with body mass index >40 kg/m(2) underwent sleeve gastrectomy and were enrolled in 4 groups, depending on the type of reinforcement used. The resected stomach specimens were treated with the same methods of reinforcement as used in the surgeries in the corresponding patients and then insufflated until a burst occurred. The burst pressures of the resected stomach specimens and adverse postoperative events were recorded. RESULTS: Five postoperative leaks occurred in the reinforcement groups (fibrin glue, 2; absorbable buttresses, 2; sutures, 1); no leaks were evident in the no-reinforcement group. Suturing afforded the highest burst pressure and took the longest to perform of the methods. There was no correlation between the leaks and burst pressures. All of the leaks occurred in the proximal fundus in the resected stomach specimens and in the affected patients. DISCUSSION: Although most surgeons use additional reinforcement on long staple lines in sleeve gastrectomy, there is no consensus about its necessity. We did not show any benefit of such reinforcement methods over proper stapling technique alone. CONCLUSION: Laparoscopic sleeve gastrectomy without staple line reinforcement is safe and avoids additional costs for reinforcement materials.
