BACKGROUND
Perforated marginal ulcers (PMUs) are a rare but known complication of bariatric surgery. Management typically involves prompt surgical intervention, but limited data exists on non-operative approaches. This study reviews published data on non-operative management of PMUs and presents a case series of patients who were managed non-operatively. Our hypothesis is that certain patients with signs of perforation can be successfully managed non-operatively with close observation.
METHODS
We completed a systematic review searching PubMed, Embase, Web of Science, Cochrane, and clinicaltrials.gov. Ultimately 3 studies described the presentation and non-operative management of 5 patients. Additionally, we prospectively collected data from our institution on all patients who presented between Dec. 2022 and Dec. 2023 with PMUs confirmed on imaging and managed non-operatively.
RESULTS
In our literature review, three patients had Roux-en-Y gastric bypass (RYGB), while two had one anastomosis gastric bypass. One patient required surgery two days after admission. Another underwent elective conversion surgery weeks later for a non-healing ulcer. Two received endoscopic interventions. One patient recovered with nil-per-os (NPO) status, and intravenous proton pump inhibitor (PPI) treatment. The patients in our case series presented with normal vital signs, an average of 30 months after RYGB, and with CT scan signs of perforation. None of these patients required surgical or endoscopic intervention.
CONCLUSION
In conclusion, while perforated marginal ulcers have traditionally been considered a surgical emergency, some patients can be successfully treated with non-operative management. More research is needed to identify the clinical presentation features, comorbidities, and imaging findings of this group.
