Abstract
Perforated duodenal ulcer following RYGB is an unusual clinical situation that may be a diagnostic challenge. Only 23 cases have previously been reported. We present five cases. The hallmark of visceral perforation, namely pneumoperitoneum, was not seen in three of the four cases that underwent cross sectional imaging. This is perhaps due to the altered anatomy of the RYGB that excludes air from the duodenum. Our cases had more free fluid than expected. The bariatric surgeon should not wait for free intraperitoneal air to suspect duodenal perforation after RYGB.
