Resection of A Solitary Peutz-Jeghers Polyp in the Jejunum Using Single-Balloon Enteroscopy: A Case Report

Hamartomatous polyps in the digestive tract are common in Peutz-Jeghers syndrome, but a solitary hamartomatous polyp in the jejunum is rare. Moreover, endoscopic resection of such a polyp has been rarely reported.A 26-year-old man underwent esophagogastroduodenoscopic and colonoscopic examination because of palpitation and melena; however, the source of the melena could not be identified. We performed a single-balloon enteroscopy via the mouth, and found a pedunculated polyp of φ30 mm on the anal side, approximately 30 cm from the Treitz ligament. Pathologically, it was a Peutz-Jeghers type hamartomatous polyp. No other polyp was detected in the jejunum or the ileum. We resected the Peutz-Jeghers polyp in the jejunum with single-balloon enteroscopy. The postoperative course of the patient was good.
