ABSTRACT
Introduction:
The staple line (SL) leak remains one of the most serious complications after laparoscopic sleeve gastrectomy (LSG). The present study aims to determine whether reinforcing the SL with sutures is effective in maintaining tissue integrity. Materials andMethods:
LSG Specimens of 60 patients were ex vivo studied. The specimens were divided into three groups In group 1, the entire SL was reinforced, while the upper half part of the SL was reinforced from fundus to antrum in group 2. The SL was not reinforced in group 3. Then, the pressure inside the sample was increased, and the bursting pressure location and pressure value during the bursting were recorded.Results:
The bursting pressure was significantly higher in entire and half oversewed SL groups than the none reinforced group (group 1 115 mmHg [95-170]; group 2 95 mmHg [80-120]; group 3 40 mmHg [22-60], respectively, [P < .001]). The most common site of bursting was in the middle â of SL (35, 53.8%), followed by the proximal â part of SL (18, 27.7%), and the distal â part of SL (12, 18.5%), respectively. The bursting site was significantly more frequent in the corpus than the other parts of the SL (P = .013).Conclusion:
Reinforcing the SL with sutures preserves tissue integrity. Although bursting was most frequently observed in the corpus region ex vivo, the fact that almost all real-life leaks develop in the area close to the Angle of His. This situation suggests that strengthening the suture line with reinforcement alone will not be protective enough against leaks in the fundus line, and factors such as tissue ischemia may be considered.Palabras clave
