A Case of Afferent Loop Syndrome Caused by Hematoma Formation due to Anastomotic Bleeding after Laparoscopic Distal Gastrectomy for Gastric Cancer

Puntos clave

• 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.
