Laparoscopic versus open right hemicolectomy: a comparison of short-term outcomes

The laparoscopic approach is increasingly becoming the gold standard for colorectal resections. While laparoscopic surgery of the left colon and rectum has been evaluated in many studies, laparoscopic resection of the right colon has not been as widely examined. The aim of this study was to examine the short-term outcomes after laparoscopic right hemicolectomies and to determine if they were superior when compared with those after open resection. Consecutive cases of laparoscopic right hemicolectomies performed between May 2005 and December 2007, in the Department of Colorectal Surgery, Singapore General Hospital, were compared with a matched series of patients who underwent open surgery. From a total of 37 laparoscopic cases, 36 patients successfully underwent laparoscopic right hemicolectomies. There was one conversion, giving a conversion rate of 2.7%. These 37 patients were compared with 40 patients who underwent open right hemicolectomies. The laparoscopic arm was characterised by shorter length of incisions (5.7 vs. 11.2 cm, p < 0.001) but longer operating times (110.8 vs. 71.6 min, p < 0.001). Mean number of lymph nodes harvested and length of proximal and distal margins were similar in both groups. There were also no significant differences between the groups in terms of narcotic use, recovery of bowel function, length of stay, post-operative morbidity and 30-day mortality. Laparoscopic right hemicolectomies are as feasible and safe as the open technique. They confer improved cosmesis with smaller incisions but at the expense of longer operating time.
