Abstract
BACKGROUND: This study was conducted to determine if laparoscopic colon surgery has changed the incidence of wound complications after colon resection. METHODS:Eighty-three patients were randomized to undergo either laparoscopic (LCR) or open colon resection (OCR) for cancer at our institution as part of a multicenter trial. Data were tabulated from review of the prospective database and physician records. RESULTS:Thirty-seven patients were randomized to LCR and 46 to OCR. Seven patients in the LCR group were converted to OCR. LCR was performed using a limited midline incision for anastomosis and specimen extraction. Incision length was significantly greater (p <0.001) in the OCR group (19.4 +/- 5.6 cm) compared to the LCR extraction site (6.3 +/- 1.4 cm). Wound infections occurred in 13.5% of patients after LCR (2.7% trocar, 10.8% extraction sites) and in 10.9% of patients after OCR. Over a mean follow-up period of 30.1 +/- 17.8 months, incisional hernias developed in 24.3% of patients after LCR and 17.4% after OCR. In the LCR group, extraction sites accounted for 85.7% of all wound complications. CONCLUSIONS: The extraction site for LCR is associated with a high incidence of complications, comparable to open colectomy. Strategies to alter operative technique should be considered to reduce the incidence of these complications.
