Purpose: Staged operation employing temporary enterostomy is still the standard treatment of malignant colonic obstruction (MCO). Expandable metal stent has been used for the palliation of unresectable gastrointestinal obstruction. We applied this metal stent technique to the MCO to achieve temporary alleviation of the obstruction so that the bowel preparation and one-stage operation were enabled. In this study we examined the efficacy of temporary indwelling of metal stent to obviate the need of staged operation in the treatment of MCO.

Methods: From December 1998 to January 2001, 35 MCO patients were treated. Patients had typical symptoms of colonic obstruction such as abdominal pain and distension. When they were admitted, an self-expandable metal stent was introduced under the guide of flexible colonoscopy. For three days, formal bowel preparation (both chemical and mechanical) were followed. With regard to achievement of bowel preparation, postoperative complications and hospital stay, these 35 patients were compared with control group (N=20) of patients who underwent two staged operations for MCO.

Results: The tumor locations were upper rectum (N=10), sigmoid colon (N=22) and left colon (N=3). Metal stent slipped off in one patient. Double contrast barium enema was possible in 34 patients. One stage operation was performed in all patients. Anastomotic complications were not observed in both groups. Intraabdominal abscess requiring reoperation was noted in one patient in each group. Wound infection was noted in 3 (8.6%) stent patients whereas 16 (80%) patients had wound complication in the control group (P<0.05). Mean hospital stay was 12.2 days in stent group and 29.4 days
in control group (P<0.05).

Conclusion: Even though our series is limited in patient number, these data suggested that temporary indwelling of self-expandable metal stent may obviate the need of staged operation in the treatment of MCO.
