Nonanastomotic Strictures After Colonic Interposition

¹ All authors: Department of Radiology, Hospital of the University of Pennsylvania, 3400 Spruce St., Philadelphia, PA 19104.

OBJECTIVE. The purpose of this study was to describe the clinical and radiographic findings in a series of patients with nonanastomotic strictures after colonic interposition.

CONCLUSION. Nonanastomotic strictures usually appear on upper gastrointestinal tract radiography as relatively long segments of smooth, tapered narrowing involving the interposed colon, most likely resulting from chronic ischemia. Unlike strictures at the esophagocolic or cologastric anastomosis, these long nonanastomotic strictures generally have a poor response to endoscopic dilatation procedures and are more likely to necessitate surgical revision of the colonic interposition.
