We report a case of endoscopic stent placement to alleviate afferent loop syndrome following recurrence of pancreatic cancer. A 73-year-old man who had undergone pancreatic duodenectomy with portal vein resection for pancreatic cancer had developed a local recurrence and was treated with chemotherapy. He developed a high-grade fever and general fatigue, and laboratory data revealed anemia and a high inflammatory reaction; therefore, he was admitted to our hospital. CT scans revealed intestinal stenosis and upper dilatation, known as afferent loop syndrome, caused by the recurrence. We safely implanted a metallic stent(non-covered Niti-S stent, Century Medical, Inc.)at the point of intestinal stenosis using a double balloon endoscope. As the stent was adequately expanded and the afferent loop syndrome was relieved, the patient was discharged with a better quality of life and there were no complications associated with the stent until he died 6 months later.
