Traditional treatment is surgery. Esophageal perforations and anastomotic leakages can be treated with endoscopically placed covered stents and drainage. We have treated selected patients with a perforated duodenal ulcer with a partially covered stent. The aim of this study was to compare surgery with stent treatment for perforated duodenal ulcers in a multicenter randomized controlled trial.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>All patients presenting at the ER with abdominal pain, clinical signs of an upper G-I perforation, and free air on CT were approached for inclusion and randomized between surgical closure and stent treatment. Age, ASA score, operation time, complications, and hospital stay were recorded. Laparoscopy was performed in all patients to establish diagnosis. Surgical closure was performed using open or laparoscopic techniques. For stent treatment, a per-operative gastroscopy was performed and a partially covered stent was placed through the scope. Abdominal lavage was performed in all patients, and a drain was placed. All patients received antibiotics and intravenous PPI. Stents were endoscopically removed after 2\u20133\u00a0weeks. Complications were recorded and classified according to Clavien-Dindo (C-D).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      43 patients were included, 28 had a verified perforated duodenal ulcer, 15 were randomized to surgery, and 13 to stent. Median age was 77.5\u00a0years (23\u201391) with no difference between groups. ASA score was unevenly distributed between the groups (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.069). Operation time was significantly shorter in the stent group, 68\u00a0min (48\u2013107) versus 92\u00a0min (68\u2013154) (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.001).
