    Abstract:
    PURPOSE: Expandable metal stents have been shown to be effective in the management of malignant large-bowel obstruction. However, right colonic lesions account for less than 5% of all reported cases of colonic stenting. This study was performed to determine the outcomes following stenting for lesions proximal to the splenic flexure. METHODS: The hospital records of patients undergoing stenting for large-bowel obstruction at a district general hospital in northeastern England from 2003 to 2008 were reviewed retrospectively. Data were analyzed to identify patient characteristics, site of obstructing lesion, intent for stenting, and outcomes measured including relief of obstruction, hospital stay, and complications. RESULTS: Stenting was attempted in 97 patients with malignant large-bowel obstruction. Of these, 16 (16.5%) patients had lesions proximal to the splenic flexure: 8 patients had lesions in the ascending colon and 8 patients had lesions in the transverse colon. Self-expanding metal stents were successful in relieving obstruction in 14 (88%) patients with proximal colonic lesions. Stenting was attempted as a bridge to definitive surgery in five patients and for palliation in nine patients. One patient had poststent bleeding that was managed conservatively, and there were no perforations or stent dislodgements. The mean postprocedure hospital stay was 1.6 days. CONCLUSIONS: Self-expanding metal stents are safe and effective in the management of malignant large-bowel obstruction proximal to the splenic flexure. The technical and clinical success rates are comparable with those reported for stenting distal colonic lesions.
