Peutz-Jeghers Syndrome Manifested as Multiple Polyps in Jejunum With Intussusception

Peutz-Jeghers syndrome (PJS) is a relatively rare autosomal dominant genetic disease, often manifested as mucous membranes, skin pigmented spots and multiple polyps in the gastrointestinal tract. It can be followed by a variety of serious complications such as bleeding, obstruction, intussusception, and malignant transformation. We introduce the case of a 26-year-old male patient who was diagnosed with multiple polyps in the jejunum with intussusception caused by PJS. He was discharged after emergency surgery reduction and partial resection of the small intestine. Gastrointestinal polyps, hemorrhage, intussusception, intestinal obstruction, and increased risk of cancer occur in patients with PJS. Currently, polypectomy under endoscopic techniques, reexamination and follow-up are the main treatment options; surgical treatment is used for bleeding, intussusception, and cancer. Therefore, it is very necessary for us to have a correct understanding of it, actively prevent it, treat it and follow these patients closely.
