ABSTRACT
Objective:To evaluate the safety and feasibility of cancer tissue specimen delivery through a preventive ostomy incision during laparoscopic radical resection of rectal cancer .Methods:A total of 155 patients undergoing laparoscopic radical rectal cancer combined with prophylactic ileostomy at Peking University Third Hospital from Oct 2016 to Sep 2021 were retrospectively divided into two groups according to where the specimens were delivered through prophylactic colostomy incision (46 cases) or through newly made suprapubic incision (109 cases).Results:The by prophylactic colostomy incision delivery group had shorter surgery time [(243±66) min vs. (281±73) min, t=3.003, P<0.01] and shorter postoperative hospital stay [(7.5±2.2) d vs. (8.8±4.3）d， t=2.516， P<0.05], while there were no significant differences in intraoperative blood loss, intraoperative blood transfusion, postoperative first time of flatus, surgery-related complications and ostomy-related complications between the two groups (all P>0.05). Though the ostomy size in the prevention colostomy group was larger ( P<0.01), but there were no significant differences in the ostomy related complications between the two groups ( P>0.05). Conclusions:Laparoscopic radical resection of rectal cancer with specimen delivery through a preventive ostomy incision is of more aesthetic advantages without causing higher postoperative complications.
