Right Colectomy for Cancer: A Matched Comparison of Three Different Surgical Approaches

Abstract

ABSTRACTPurpose. The standard approach to right colon cancer resection is still a matter of debate and includes laparoscopy, open midline incision, or open transverse incision. We aimed this study to compare the short- and long-term results of laparoscopic right-colectomy with those provided by the open approaches. Methods. Of the 176 patients who underwent right-colectomy at our Department for nonmetastatic colon cancer, 40 patients treated by laparoscopy, 40 treated by transverse incisions, and 40 treated by midline incisions were selected and matched using the propensity score method. Short-term results included: operating time, morbidity rate, number of lymph-nodes harvested (LNH), patients’ recovery features, and costs. Long-term results included: disease-specific survivals and the rate of incisional hernias. The sub-groups were compared using t-test and Chi-square tests, whereas the Kaplan-Meier method was used to assess survivals. Results. Laparoscopies were the longer procedures, providing similar morbidity rates and LNH in comparison with the open approaches. Laparoscopy provided a faster return to oral intake and a shorter use of analgesics comparing with the midline approach; however, it showed only a minor consumption of analgesics in comparison with transverse laparotomy. There were no differences in the hospital stay and the long-term results were comparable between sub-groups. Costs analysis documented minor but not significant surgical expenses for the transverse approach. Conclusions. Laparoscopy was documented safe, with similar morbidity rates and long-term results comparing with open surgery. Laparoscopy provided better functional short-term results comparing with the midline approach, but only small differences with respect to the transverse incision approach.
