Early postoperative results of a prospective series of laparoscopic vs. Open anterior resections for rectosigmoid cancers.

PURPOSE: This study was undertaken to compare postoperatively laparoscopic (LAR) with open (OAR) anterior resection in patients with rectosigmoid cancers.

METHODS

Forty consecutive patients were divided into two groups: 20 patients (9 males) were allocated to LAR and 20 patients (6 males) to OAR.

RESULTS

Median age in the LAR group was 62 (range, 39-77) years, and in the OAR group, it was 61 (range, 43-84) years (P = 0.9). Median lengths of the distal margin of clearance beyond the tumor were 4 (range, 2-8) cm and 4.5 (range, 3-7.5) cm in the LAR and OAR groups, respectively (P = 0.35). Median numbers of lymph nodes harvested were 20 (range, 7-49) and 19 (range, 7-97) for the LAR and OAR groups, respectively (P = 0.44). Median operating times were 90 (range, 55-185) minutes and 73 (range, 40-140) minutes in the LAR and OAR groups, respectively (P = 0.08). Blood losses were 50 (range, 50-800) ml and 50 (range, 50-1,500) ml in the LAR and OAR groups, respectively. There was no intraoperative complication in either group, and no laparoscopic patient was converted to an open procedure. Median length of extraction site incision in the LAR group was 5.5 (4-13) cm, and length of incision in the OAR group was 18 (8-25) cm (P < 0.002).

CONCLUSION

There were no significant differences between the two groups with regard to duration of parenteral analgesia, starting of fluid and solid diet after surgery, or time to first bowel movement and time to discharge from the hospital.
