Single-stage procedure with intraoperative colonoscopy and colonic irrigation in patients with obstructing left-sided colonic cancer.
OBJECTIVE
Recently there has been growing acceptance of the one-stage resection and primary anastomosis with intraoperative antegrade irrigation. This study evaluated the efficacy of a newly developed device for performing a single-stage procedure in patients with obstructing left-sided colon cancer.


METHODS
A series of 151 consecutive patients with obstructing left-sided colonic cancer underwent on-table irrigation, resection, and primary anastomosis with the use of a newly developed device; 75 patients on-table colonoscopy. The study spanned a 3 years from September 1999 to August 2002. The observed variables were the volume of irrigated saline, time for irrigation and colonoscopic examination, synchronous pathology, operative mortality and morbidity, time to passage of flatus, restarting day of oral intake, and length of hospital stay.


RESULTS
The mean volume of irrigated saline was a mean of 12.5 l (range 1-32) over a mean of 14.2 min (range 1-45). Subsequent colonoscopic examination added a mean of 10.7 min (range 3-15). The incidence of synchronous polyps was 47% (35 of 75 cases) in performing the on-table colonoscopic investigations. On-table colonoscopy induced surgeons to extend resection because of synchronous malignancy attested by frozen biopsy specimen in ten patients and because of mucosal necrosis of the proximal colon in three. There were two anastomotic leakages, six wound infections, and one operative mortality. The time to passage of flatus was an average of 3.6 days (range 1.0-7). The time to oral intake was an average of 4.3 days (range 3-8). The length of hospital stay was 11.7 days (range 6-43).


CONCLUSIONS
These findings suggest that our device is an effective tool to facilitate acceptance of the one-stage procedure in patients with obstructing left-sided colonic cancer. Specifically, our device enables quick and easy on-table colonoscopy.
