Purpose: Laparoscopic total abdominal colectomy and total proctocolectomy are technically challenging operations. Advances in minimally invasive techniques, including sleeveless hand-assist devices, may influence performance of these procedures. This study was designed to evaluate the results of laparoscopic total colectomy and to compare the hand-assisted approach with straight laparoscopy.
Methods: Sequential patients undergoing hand-assisted and straight laparoscopic total abdominal colectomy and total proctocolectomy from 1997 to 2004 were identified from a single institution prospective database involving four colorectal surgeons, of which three had limited laparoscopic experience. Patient characteristics, perioperative parameters, and outcomes were assessed.
Results: A total of 130 patients were analyzed. Sixty-nine patients underwent total abdominal colectomy (hand-assisted 17 vs. straight laparoscopic 52), and 61 underwent total proctocolectomy (hand-assisted 28 vs. straight laparoscopic 33). For both total abdominal colectomy and total proctocolectomy, the hand-assisted and straight laparoscopic groups were well matched. Although no differences were observed in operative blood loss and intraoperative complications, hand assistance resulted in fewer overall conversions to open (1/45 (2.2 percent) vs. 6/85 (7.1 percent); P < 0.01), with no conversions in the total abdominal colectomy group (0 vs. 9.6 percent; P = 0.05). There was a trend toward reduced operative time with hand assistance, and nonlaparoscopic staff surgeons performed a greater proportion of the hand-assisted cases (22.2 vs. 10.6 percent; P < 0.05).
Conclusions: Laparoscopic total colectomy is technically feasible and safe. With a significant reduction in conversions and a greater proportion of cases performed by nonlaparoscopic surgeons, there was an evolutionary shift to a hand-assisted technique. A hand-assisted approach may be a useful alternative to a straight laparoscopic approach for this technically challenging operation.
