Routine Staple Line Reinforcement for Minimally Invasive Distal Pancreatectomy

Postoperative fistula is the major complications of distal pancreatectomies which prohibit patients' recovery. Previous studies have reported controversial results regarding the efficacy of pancreatic stump reinforcement methods. Prior research has commonly included minimally invasive and open cases together. Moreover, stapler and suture were combined in most studies making interpretation difficult. Data has shown that staple line plus reinforcement might potentially decrease the CR-POPF rate of patients who underwent distal pancreatectomies, but well-designed high-quality evidence is lacking. Thus, the investigators design the present study to the question that whether routine staple line plus reinforcement would bring benefit for participants.
