Perforated Peptic Ulcer of the Duodenum After the Laparoscopic Roux-en-Y Gastric Bypass

Abstract

Perforated ulcers of the gastric remnant and duodenum seem to be a rare complication after a Roux-en-Y gastric bypass. Diagnosis of this complication can be difficult given a vague presentation, however, early intervention is critical to prevent further morbidity. We present the case of a 38-year-old male with a perforated duodenal ulcer nearly a year after Roux-en-Y gastric bypass. Upon presentation, he complained of 8 hours of epigastric pain. His medical history was significant for chronic peptic ulcer disease and a negative history of H. pylori. Recently, he had been prescribed naproxen by his primary care physician for knee pain. His vital signs were normal with the exception of his systolic blood pressure which was 190 mmHg. He was diaphoretic and peritonitic on exam. He was taken emergently for a diagnostic laparoscopy and found to have a perforation of ∼5 mm of the anterior portion of his duodenum. This was repaired laparoscopically with an omental patch and the patient recovered without any further intervention required. While this is a rare complication reported in the literature, this or similar complications of the remnant stomach may be underrepresented in publications. The surgical intervention of this disease will either be resection of the remnant or an omental patch. However, controversy remains as to the proper post-operative medical treatment. For our patient, the inciting agent was likely the naproxen he was given and this was stopped immediately. Patient education and ownership should remain a cornerstone for patients that have undergone a Roux-en-y gastric bypass.
