Colonic obstruction caused by endometriosis solved with a colonic stent as a bridge to surgery.

Self-expanding metal stents are an established treatment for malignant colon strictures, either as palliative treatment or as a bridge to later surgery. Little data exist regarding the use of stents for benign obstructions and the rate of subsequent complications related to the procedure is high. After reviewing the existing literature, we found only one case of stent placement in an intestinal obstruction caused by endometriosis, as a bridge to surgery.

Efficacy of intralesional corticosteroid injection in endoscopic treatment of esophageal strictures.

Background: The present study was conducted to determine the effectiveness of intralesional triamcinolone to improve the results of endoscopic dilation in esophageal strictures.

Methods: We treated 9 patients with complex strictures of different etiologies (2 postsurgery, 3 gastroesophageal reflux disease, and 4 caustic) with intralesional injections of triamcinolone followed by endoscopic dilations. Outcomes of triamcinolone-treated patients were compared with those of historical control.
