Laparoscopic versus transverse Incision right colectomy for colon carcinoma

We investigated whether laparoscopic right colectomy has short-term and ⁄ or oncological advantages compared with transverse incision right colectomy.

Patients who underwent an elective laparoscopic right colectomy or an open right colectomy through a transverse incision at the VU University Medical Center or Zaans Medical Center from 2005 to 2009 were prospectively followed.

Patient groups were comparable in terms of gender, body mass index and American Society of Anesthesiology classification. Patients in the transverse incision group were older (68 years vs 75 years, P = 0.07) and blood loss was greater during this procedure (60 ml vs 130 ml, P = 0.001), which cost less than the laparoscopic procedure (€6.033 vs €7.221, P = 0.03). Hospital stay for the laparoscopic group was shorter (8 days vs 9 days, P = 0.04), but laparoscopic procedures took longer (155 min vs 77 min, P < 0.001) and 8% of patients in the laparoscopic group were converted to a median laparotomy. Postoperative complications were comparable for both groups (28% vs 32%, P = 0.74), and in both groups a radical resection rate of 96% (P = 0.94) was achieved. At a median follow up of 20 months the incidence of incisional hernia was similar in both groups and no patient required additional surgery as a result. Overall survival at 60 months was 70% for the laparoscopic group and 67% for the transverse incision group (P = 0.84).

There a re few clinically relevant differences between a laparoscopic right colectomy and a transverse incision right colectomy. Transverse incision right colectomy is cheaper. The study may be the first to compare these two techniques, but it is a nonrandomized trial and therefore has its limitations.
