Totally laparoscopic versus laparoscopic-assisted left colectomy for cancer: a retrospective review

Background Laparoscopic left colectomy (LLC) became the standard of care for treating distal transverse and descending colon cancer in many centers. Most centers use laparoscopic-assisted colectomy with extracorporeal anastomosis (LAC/EA). A totally laparoscopic colectomy with intracorporeal anastomosis (TLC/IA) has been proposed. The purpose of our study is to compare these two techniques. Methods A series of 52 patients undergoing LLC for left-sided colon cancer was retrospectively evaluated. Thirty-three patients underwent TLC/IA, and 19 underwent LAC/EA. The following data were collected: gender, age, body mass index, American Society of Anesthesiologists risk class, operation duration, conversion to laparotomy, intraoperative complications, postoperative complications, postoperative course (duration of stay, time to first flatus), number of excised lymph nodes, readmission, and reoperation rates. Data were prospectively recorded in a colorectal cancer database and retrospectively analyzed. Results The only demographic parameter that differed significantly between the groups was age (64.2 ± 12.4 years for the TLC/IA group, vs. 72.7 ± 2.1 years for LAC/EA, p = 0.0116). The mini-laparotomy incision was significantly shorter in the TLC/IA than in the LAC/EA group (5.8 ± 0.9 vs. 8.2 ± 0.9 cm, respectively, p
