title: Is complete laparoscopic colectomy superior to laparoscopic assisted colectomy?
abstract: Much debate has centered around what constitutes a true laparoscopic colon resection. Purists argue that intracorporeal division of the mesentery and anastomosis confer a benefit over a "laparoscopic assisted" procedure. The aim of this study was to further examine this issue. Data were prospectively collected on 102 consecutive laparoscopic colon resections. Five procedures were converted to open cases and were excluded from analysis. Procedures were divided into two groups. Group 1 (n = 34) consisted of complete laparoscopic procedures (no abdominal incision was made): abdominoperineal resection (3), Hartmann's reversal (3), end colostomy (7), low anterior resection (5), proctectomy (1), sigmoid colectomy (15). Group 2 (n = 63) consisted of laparoscopic "assisted" procedures (i.e., an incision was made to facilitate anastomosis, division of the mesentery, and/or specimen retrieval): Ileocolic resection (6), restorative proctocolectomy (26), right colectomy (19), subtotal colectomy/end ileostomy (5), subtotal colectomy/ileorectal anastomosis (7). Length of hospitalization and duration of postoperative ileus were compared. A subset analysis of right colectomy (intracorporeal mobilization and extracorporeal division of the mesentery and anastomosis) versus sigmoid colectomy (intracorporeal mobilization, division of the mesentery and anastomosis) was also performed. There were no statistically significant differences in length of hospital stay (Group 1, 7.47 +/- 2.75 days; Group 2, 7.78 +/- 5.55 days) or duration of postoperative ileus (Group 1, 3.24 +/- 1.56 days; Group 2, 3.68 +/- 1.58 days). Similarly, in the sigmoid colectomy versus right colectomy subset analysis, there were no statistically significant differences in length of hospital stay (sigmoid colectomy, 7.92 +/- 2.90 days; right colectomy, 6.40 +/- 1.50 days) or duration of postoperative ileus (sigmoid colectomy, 3.36 +/- 1.39 days; right colectomy, 3.18 +/- 1.07 days). Our data demonstrate that intracorporeal division of the mesentery and anastomosis confer no advantage over the laparoscopic assisted procedures. Data were prospectively collected on 102 consecutive laparoscopic colon resections. There were no statistically significant differences in length of hospital stay or duration of postoperative ileus regardless of whether intracorporeal or extracorporeal mesenteric division and anastomosis were undertaken. These data demonstrate that a completely laparoscopic procedure does not appear to offer any advantage as compared to a laparoscopic assisted one.
