Key Points

To report a case of afferent loop syndrome caused by hematoma after laparoscopic distal gastrectomy for gastric cancer.
An 88-year-old male underwent laparoscopic distal gastrectomy with Roux-en-Y reconstruction for early gastric cancer.
Emergency endoscopy revealed hematoma at the anastomosis causing afferent loop syndrome.
Intervention involved endoscopic removal of the hematoma and clipping of the bleeding site.
Patient experienced abdominal distention and hematemesis two days post-surgery.
Endoscopic intervention improved dilation of the afferent loop.
Afferent loop syndrome was diagnosed due to anastomotic bleeding, leading to compression from hematoma.

Implication

Uncovers afferent loop syndrome due to hematoma post-gastric surgery, indicating rare complications.
