暂无%X A 28-year-old female with a history of treatment for small intestinal polyps and characteristic pigmentation of her lip was clinically diagnosed with Peutz-Jeghers syndrome(PJS). Her sister had the pathogenic variant of STK11 upon genetic testing. A 20-mm polyp was identified in the second part the patient's duodenum on routine gastrointestinal surveillance, and biopsy revealed a well-differentiated adenocarcinoma. Laparoscopic partial duodenectomy with endoscopy was planned. After confirming the location of the tumor and Kocherization using a laparoscope, the polyp was resected via submucosal dissection under direct visualization with a small incision. The polyp was diagnosed as well-differentiated adenocarcinoma in situ and was resected without remnants. PJS is characterized by a high incidence of malignant tumors, and lifelong surveillance for gastrointestinal and extra-gastrointestinal tumors is necessary. The incidence of duodenal cancer is not high among patients with PJS. However, surgery for advanced cancer is highly invasive. It is desirable to detect the tumors at an early stage so that they can be resected via a less invasive treatment method such as endoscopic resection or laparoscopic surgery with an endoscope.
