Acute intussusception and polyp with malignant transformation in Peutz-Jeghers syndrome: A case report.

Intussusception is one of the most frequent complications of Peutz-Jeghers syndrome, and has been well described in previous studies. More attention has been paid to malignancy, which is another complication of Peutz-Jeghers syndrome and which leads to increased mortality. Few cases of intussusception combined with malignant polyps in Peutz-Jeghers syndrome have been reported to date. In the present study, we report a case of intussusception and malignant polyps occurring in various parts of the small intestine in a 43-year-old male. In addition to repair of the intussusception and partial resection of the small intestine with malignant polyps, we also simultaneously performed polypectomy of as many polyps as possible without resection of the small intestine. Our aim is to make clinicians aware of intussusception and malignant polyps coexisting in Peutz-Jeghers syndrome when performing emergency surgery. Prophylaxis and polypectomy of the entire small bowel is an effective way to reduce the frequency of laparotomies in patients with this disease.
