Computed tomography assessment of postoperative gastric vascular supply and staple-line leak development after sleeve gastrectomy.

Background: Residual arterial supply of the gastric tube after sleeve gastrectomy (SG) can be damaged by surgery, which can reduce gastric tube perfusion and could promote postoperative leakage.

Objective: To compare the postoperative vascularization of the gastric tube using early computed tomography (CT) scanning after SG in patients with or without postoperative staple-line leak.

Setting: University hospital.
