title: Small bowel polyps in Peutz-Jeghers syndrome: management by combined push enteroscopy and intraoperative enteroscopy.
abstract: BACKGROUND
  Polyps occur throughout the GI tract in Peutz-Jeghers syndrome; the major problem in the management of the syndrome lies in the small bowel.
  
  
  METHODS
  From January 1979 to January 1998, seven patients with Peutz-Jeghers syndrome underwent surveillance. Between 1979 and 1992 they were managed with upper and lower endoscopy every 2 to 3 years and surgery when intestinal obstruction occurred. From 1993 they also underwent enteroclysis and, on the basis of radiologic findings, push enteroscopy and/or intraoperative enteroscopy. Push enteroscopy was then performed every 2 years in all patients.
  
  
  RESULTS
  During the first period, 5 of 7 patients underwent emergency small bowel resection (2 operated twice). The patients were divided into 2 groups based on enteroclysis findings; the first comprised 4 patients with multiple polyps throughout the small bowel, and the second included 3 patients with polyps only in the proximal small bowel. Three of the 4 patients with diffuse polyposis underwent intraoperative enteroscopy during which on average 16 polyps per patient were removed (range 10 to 25 polyps; mean diameter 16 mm, range 3 to 50 mm). The remaining patient with diffuse polyposis had a single 25 mm polyp in the terminal ileum removed by retrograde ileoscopy; the more proximal polyps were removed by push enteroscopy. The patients with diffuse polyposis remained asymptomatic during follow-up (mean 50 months, range 47 to 57 months) and also underwent periodic push enteroscopy (mean 2.25 enteroscopies per patient, range 2 to 3) at which a mean of 8.5 polyps per patient (range 4 to 13 polyps) were removed (mean diameter 7.2 mm, range 3 to 15 mm). The 3 patients of the second group underwent periodic push enteroscopy alone (mean 3 per patient) during which a mean of 11.7 polyps per patient were removed (range 7 to 15 polyps: mean diameter 10.9 mm, range 3 to 40 mm). Enteroclysis was not repeated in these patients, who remained asymptomatic during follow-up (mean 47 months, range 46 to 48 months).
  
  
  CONCLUSIONS
  More effective clearance of small bowel polyps via enteroscopy will help reduce the need for emergency surgery with extensive intestinal resection in patients with Peutz-Jeghers syndrome.
