Iatrogenic rectal perforation due to application of topical treatment in a patient with ulcerative colitis: a rare complication.

Rectal perforations due to topical treatments (enemas or foams) are unusual complications and they have been mostly reported in the use of barium enemas or in elderly patients with constipation. Very little has been reported about perforations secondary to topical treatment in patients with ulcerative colitis. We present the case of a patient with ulcerative colitis who suffered a rectal perforation complicated with a superinfected collection after the application of topical mesalazine foam.

The role of lumen-apposing metal stents (LAMS) in iatrogenic esophageal perforations secondary to endoscopic dilation of benign short esophageal strictures.

81 year-old male had an asymptomatic iatrogenic perforation after balloon dilation of esophageal strictures. After the migration of the full covered self expandable metal stent (FCSEMS), a lumen-apposing metal stent (LAMS) was placed and no esophageal leak was seen after. LAMS could be an appropiate first-line approach to benign short esophageal strictures complicated with iatrogenic small perforation but further prospective studies are needed.
