nitinol and Duodenal-Ulcer

A 93-year-old patient underwent endoscopic treatment of perforated duodenal ulcer after previous laparoscopic suturing complicated by failure of sutured defect. A self-expanding nitinol stent with partial polyurethane coating was used. Positive effect of the treatment was noted. Further study of this method and its clinical introduction in case of favorable results can significantly reduce the incidence of complications and mortality in patients with perforated gastroduodenal ulcers.. Описание клинического случая эндоскопического лечения перфоративной язвы двенадцатиперстной кишки.. Пациентке в возрасте 93 лет выполнили эндоскопическое лечение перфоративной дуоденальной язвы после ее лапароскопического ушивания, осложнившегося несостоятельностью ушитого дефекта. Для лечения использовали саморасширяющийся нитиноловый стент с частичным полиуретановым покрытием.. Отмечен положительный эффект от проведенного лечения.. Дальнейшее изучение предложенного метода и благоприятные результаты его внедрения в клиническую практику могут значительно снизить частоту осложнений и летальности при перфоративных гастродуоденальных язвах у пациентов с высоким риском осложнений послеоперационного периода.

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.

Migration, distal malposition or fracture of self-expanding metallic biliary or esophageal stents rarely occur but may lead to stent dysfunction, mucosal trauma secondary to impaction or friction on the digestive wall. We report our experience of using argon plasma to endoscopically cut three metallic biliary and esophageal self-expanding stents to restore permeability or to treat impaction of the stent after migration, malposition or fracture.
