Minimally invasive colectomy: Are the potential benefits realized?

Abstract

Laparoscopic surgical techniques have recently been applied to various types of colon resection. Early reports have focused on the technical feasibility of these procedures, and it has not yet been clearly shown that such procedures benefit the patient. We reviewed our experience with 28 attempted minimally invasive colectomies (MICs) performed over a nine-month period. Laparoscopic or laparoscopic-assisted resections were successfully completed in 24 of these patients. We compared the results of surgery in these 24 patients with a group of 33 patients undergoing similar procedures at the same institution by the same surgeon in the nine months preceding the laparoscopic experience. The two groups of patients were similar with respect to age, weight, and the types of procedures performed. However, the postoperative length of stay for patients undergoing MIC (4.8 days) was significantly shorter than for those undergoing open colectomies (8.2 days). Patients undergoing MIC also regained bowel function significantly earlier than those undergoing open colectomy. The operative times for the minimally invasive procedures were significantly longer than for those undergoing open colectomy. No surgically related deaths were encountered, and morbidity was 13 percent. None of the four patients converted from laparoscopic to open colectomy suffered complications as a result of the attempted laparoscopic procedure. We conclude that MIC can be safely performed and does appear to reduce the duration of postoperative ileus and decrease the length of postoperative hospitalization.
