Endoscopic therapy of small-bowel polyps by double-balloon enteroscopy in patients with Peutz-Jeghers syndrome
Gastrointestinal Endoscopy , Volume 71 - Issue 4 p. 768- 773
Background: Peutz-Jeghers syndrome (PJS) is a hereditary disorder characterized by mucocutaneous pigmentations and hamartomatous polyps mainly in the small bowel. These polyps may cause complications such as intussusception. Objective: To assess therapeutic efficacy and safety of double-balloon enteroscopy (DBE) for detection and treatment of small-bowel polyps in patients with PJS. Design: Prospective cohort study. Setting: Tertiary-care referral center. Patients: This study involved 13 patients with PJS, defined as a proven STK11 gene mutation or according to international diagnostic criteria. Intervention: DBE with enteroscopic removal of pedunculated polyps of ≥10 mm. Main Outcome Measurements: Location, number and size of small-bowel polyps, polypectomy data, and complications and long-term complications associated with development of small-intestine polyps. Results: Thirteen patients with PJS (8 male, mean age 31 years) underwent 29 DBE procedures. Ten patients (77%) had a history of partial small-bowel resection because of small-bowel polyps. Small-bowel polyps were found in all 13 patients. The majority of polyps (94%) were located in the proximal jejunum. A total of 82 polyps of ≥10 mm were detected, and 79 (96%) were endoscopically removed without complications. After the introduction of DBE, no small-intestine-polyp-related complications occurred during a follow-up period of 356 person-months. Limitations: Small number of patients. Conclusion: DBE is clinically useful and safe for diagnosis and therapy of small-bowel polyps in patients with PJS, even in patients with a history of extensive abdominal surgery. DBE may decrease the need for laparotomy in patients with PJS.
