Comparative short-term and survival outcomes of three specimen extraction techniques in laparoscopic low rectal cancer surgery: does it affect ileostomy closure?

Introduction This study aimed to compare the short-term and survival outcomes in laparoscopic low rectal cancer surgery with three different specimen extraction techniques, and whether it affects loop ileostomy closure. Materials and methods A consecutive series of patients with low rectal cancer who underwent laparoscopic low anterior resection plus protective loop ileostomy (LAR-PLI) were enrolled. Three main techniques, namely specimen extraction through auxiliary incision (EXAI), specimen extraction through stoma incision (EXSI), and specimen eversion and extra-abdominal resection (EVER), were employed. The postoperative short-term and survival outcomes of the three techniques and the impact on loop ileostomy closure were compared. Results In all, 254 patients were enrolled in this study: 104 (40.9%) in the EXAI group, 104 (40.9%) in the EXSI group, and 46 (18.1%) in the EVER group. For primary surgery, EXAI group had significantly longer operative time (P Conclusions Our single-center results found that in LAR-PLI surgery for low rectal cancer, the short-term outcomes of specimen extraction through the stoma incision or anus were better than that through the auxiliary incision, but the 3-year LRFS was no statistically different.
