Endoscopic treatment of perforated duodenal ulcer using a partially polyurethane-covered self-expandable nitinol stent: A case report.

We describe a clinical case involving endoscopic treatment of a perforated duodenal ulcer using a partially polyurethane-covered self-expandable nitinol stent. A 93-year-old patient with severe cardiovascular comorbidity underwent a laparoscopic closure of a perforated duodenal ulcer. The early postoperative period was complicated by failure of the closure, and as a result, endoscopic treatment was performed, including the placement of a partially polyurethane-covered self-expandable nitinol stent. The treatment had a positive effect. Further study of the proposed method is required, and favorable results will allow endoscopists to actively introduce this procedure into clinical practice.
