Mass Continuous Suture versus Layered Interrupted Suture in Transverse Abdominal Incision Closure after Liver Resection

Background Abdominal incision closure technique seriously influences patient prognosis. Most studies have focused on the different suture techniques and materials on midline incision, while little data are available in wide transverse or oblique incisions after liver resection (LR). The aim of the present study is to compare the two major incision suture methods after LR in our institute: Mass continuous suture (group P) and layered interrupted suture (group S). Study design 258 patients undergoing LR with abdominal transverse or oblique incisions were prospectively enrolled. They were divided into two groups according to different abdominal incision suture methods and compared with the preoperative, intraoperative parameters, and postoperative wound complications. Results There were 118 patients in group P and 140 patients in group S, which was similar in general condition, primary disease, liver, and renal function. Incision length, total operation time, intraoperative blood loss, or perioperative antibiotics use were not different between the two groups. However, abdominal incision closure time and interval time for stitches removing after operation was significantly shorter in group P than group S (both p
