[A Case of Endoscopic Stent Placement for Jejunal Stenosis with Two Curvatures Due to Peritoneal Dissemination after Total Gastrectomy].

A 74-year-old man underwent total gastrectomy with Roux-en-Y reconstruction for gastric cancer in May 2019. Three years postoperatively, he developed epigastric discomfort, and imaging studies revealed peritoneal dissemination leading to jejunal stenosis. He was admitted for stent placement. Endoscopic examination revealed 2 stenotic sites with curvatures at 3 cm and 6 cm distal to the esophagojejunal anastomosis, making guidewire passage difficult using a standard-diameter endoscope. A small-caliber transnasal endoscope was employed, successfully passing through the stenotic sites and enabling proper stent placement. After stent insertion, the patient was able to maintain oral intake until shortly before death due to disease progression, contributing to improved quality of life.
