Comparison of intraoperative enteroscopy and double-balloon enteroscopy for the diagnosis and treatment of Peutz-Jeghers syndrome

Abstract

Background: Double-balloon enteroscopy (DBE) is an enteroscopy method that allows examination and treatment of the small bowel. Intraoperative enteroscopy (IOE) was the only possibility of endoscopic treatment for patients with Peutz-Jeghers syndrome (PJS) before the DBE era. PJS is an inherited, autosomal dominant disorder distinguished by hamartomatous polyps in the gastrointestinal tract and pigmented mucocutaneous lesions. PJS predisposes sufferers to various malignancies. Bleeding, obstruction, and intussusception are common complications in patients with PJS. The goal of this study was compare our experience in diagnosis and treatment of small-bowel hamartomas by means of DBE and IOE.

Methods: From 1999 to 2006, we performed seven IOEs in seven patients (four women, three men), and since 2006, 14 DBEs in another ten patients (seven women, three men).

Results: A total of 182 polyps were removed during IOEs: 179 by the endoscopist and three were cut out by the surgeon. From 6 to 75 polyps were removed per session (mean, 26). The largest hamartoma measured 4 cm in diameter. The age of the patients ranged from 20 to 50 (mean, 31) years. In our DBE group, a total of 205 polyps were removed. From 1 to 37 polyps were removed per session (mean, 13). The age of the patients ranged from 12 to 48 (mean, 25) years. The largest hamartoma was 6 cm in diameter. We had no serious complications both in the IOE and the DBE group.

Conclusions: Polypectomy using DBE may obviate the need for repeated urgent operations and small-bowel resections leading to short-bowel syndrome. Patients are indicated for prophylactic procedure and polypectomy of the entire small bowel. Both DBE and IOE facilitate exploration and treatment of the small intestine. DBE is less invasive and more convenient for the patient. Both procedures are generally safe and useful.
