Metallic Stent Placement For Treatment Research Articles

Successful management of a benign anastomotic colonic stricture with self-expanding metallic stents: A case report

To assess the effectiveness of and complications associated with metallic stent placement for treatment of anastomotic colonic strictures. A 46-year-old man undergoing two procedures of surgery for perforation of descending colon due to a traffic accident presented with pain, abdominal distention, and inability to defecate. Single-contrast barium enema radiograph showed a severe stenosis in the region of surgical anastomosis and the patient was too weak to accept another laparotomy. Under fluoroscopic and endoscopic guidance, we placed two metallic stents in the stenosis site of the anastomosis of the patient with anastomotic colonic strictures. In this case of postsurgical stenosis, the first stent relieved the symptoms of obstruction, but stent migration happened on the next day so an additional stent was required to deal with the stricture and relieve the symptoms. This case confirms that metallic stenting may represent an effective treatment for anastomotic colonic strictures in the absence of other therapeutic alternatives.

Metallic stents in the treatment of benign diseases of the colon: preliminary experience in 10 cases.

To assess the effectiveness of and complications associated with metallic stent placement for treatment of benign diseases of the colon. With radiologic guidance, the authors placed metallic stents in 10 patients with benign diseases of the colon: Nine stents were placed in the rectosigmoid colon, and one was placed in the descending colon. The stents were placed in two cases of diverticulitis complicated by pelvic abscess, four cases of colonic fistula following surgery, and four cases of postsurgical anastomotic stricture. Coated stents were placed in the cases involving fistulas and diverticulitis. In the two cases of diverticulitis complicated by pelvic abscess, the coated stents helped to resolve the abscesses, but both patients subsequently developed complications: fistula and perforation. Of the four cases of colonic fistula, two were resolved with stent placement. In the four cases of postsurgical stenosis, the stents temporarily relieved the symptoms of obstruction, but additional treatments were required before the patients became entirely asymptomatic. Metallic stents may represent an effective temporary treatment for certain benign colonic conditions in the absence of other therapeutic alternatives.
