A 10-year review of our experience with all patients with symptoms of colonic narrowing (n = 61) revealed 14 patients who were treated endoscopically. The site of narrowing was the sigmoid colon in 12 patients and the rectum in two patients. The
strictures occurred after anastomosis in seven patients, with
carcinoma in four patients, and with inflammatory disease, external compression, and idiopathy in one patient each. Although combinations of endoscopic techniques were occasionally used, the predominant method responsible for successful management of the narrowing was bouginage in four patients, endoscopy with a prototype dilating
endoscope in four patients, balloon dilatation in three patients, and
electrocautery and
laser surgery in one patient each. There were no perforations or
bleeding complications. Repeated treatments were usually needed. As less invasive methods evolve to treat colonic narrowing, appropriate matching of available techniques with the underlying disease becomes easier. We have found that dilation with a bougie, balloon, or a prototype dilating
endoscope can provide especially beneficial results when used on patients with
strictures resulting from inflammatory disease or external compression. Cutting and ablating tools such as the
electrocautery and
laser tools are more suited for management of
strictures that result from
carcinoma and anastomotic webs. Appropriate matching of endoscopic technique to underlying colonic pathology will allow increasingly successful and safer management of colonic narrowing without operation.
