INTRODUCTION AND IMPORTANCE: Roux-en-Y gastric bypass (RYGB) is one of the two most common weight loss surgeries. Surgical emergencies after gastric bypass can be complicated by devastating events that are often difficult to diagnose and manage. Perforated ulcers are a very rare complication after a RYGB.
CASE PRESENTATION: In this report, the diagnosis and surgical management of a 59-year-old immunosuppressed male patient who presented with late perforation of a pre-pyloric ulcer in the gastric remnant after RYGB is presented. The perforation was repaired transversely in a running horizontal mattress fashion and patched with a piece of well-vascularized omentum.
CLINICAL DISCUSSION: This case illustrates the potential for gastric remnant ulceration, even a decade after RYGB. A high degree of suspicion for the diagnosis of perforated remnant stomach is required, especially in the absence of pneumoperitoneum and free fluid. Patient-specific factors, such as immunosuppression in this case, may blunt normal physiologic response.
CONCLUSION: Considering the location of the ulcer in the pre-pyloric area, we caution that the typical paradigm of marginal ulceration of the gastro-jejunal anastomosis does not always apply when evaluating gastric complications after RYGB.
