Endoscopic stent treatment of a duodenal ulcer perforation.

required because of persistent leakage from perforated ulcers or if the perforations are larger than 2–3 cm. Common alternatives are a novel Graham patch closure, Billroth procedure, jejunal serosal patch, and duodenojejunostomy with a Roux-en-Y anastomosis [1,2]. Many of these are complicated surgical procedures which require prolonged general anesthesia. Our patient, an 81-year-old man, was admitted with a perforated duodenal ulcer and underwent laparotomy 37 hours after onset of symptoms. The 0.5-cm, large perforation was closed with two resorbable polyfilament cross-sutures. The patient was then reoperated twice due to persistent leakage, initially with a traditional Graham patch closure and later, aided by a small laparotomy, we used a gastroscope and a guide wire to deliver a duodenal stent, (90 × 23mmWallFlex, Boston Scientific Norge AS, Asker, Norway) to cover the defect. Unfortunately the stent was damaged during the procedure (●" Fig. 1). The patient then underwent another gastroscopy. The defective stent was removed, and the perforation, which was estimated to be just over 1 cm in diameter during the endoscopy, was located and, through the working channel of the gastroduodenoscope, a covered proximal release metal stent with a 90-mm long cover, designed for treatment of malignant strictures in the esophagus (100 × 23mm Boston Ultraflex), was placed with the distal end in the third part of the duodenum. Following this procedure, the leakage reduced quickly. Migration of covered stents is a common problem with a migration rate of more than 20% [3,4]. At 12 months after the placement, the stent placed in our patient migrated and caused small-bowel obstruction. The patient was again operated, with a McBurney incision in the right fossa. The ileum was resected (approximately 5 cm), and the migrated stent removed at the same time (●" Figs. 2, 3). A literature search found no reports of similar attempts using endoscopic stents for duodenal ulcer perforations. We believe that this method can be an alternative for selected patients, combined with percutaneous draining of the abdominal cavity.
