## Contribution

The paper introduces a novel surgical treatment for acute superior mesenteric artery syndrome using a bariatric procedure.

## Key findings

- The patient presented with acute superior mesenteric artery syndrome complicated by gastric necrosis.
- A single anastomosis sleeve jejunal bypass was successfully used as a treatment approach.
- The case highlights the potential of bariatric surgical principles in managing this rare condition.

## Abstract

Superior mesenteric artery syndrome is a rare vascular compression syndrome in which the duodenum is compressed between the aorta and the overlying superior mesenteric artery. This condition is often chronic and secondary to cachexia. It can trigger further weight loss due to the subsequent proximal intestinal obstruction, causing a positive feedback loop. We report a case of acute presentation of superior mesenteric artery syndrome, complicated by gastric necrosis and treated surgically using the principles of a novel bariatric procedure.
