Abstract

Objective To analyze the endoscopic features of colorectal submucosal tumors(SMTs) and to explore the treatment strategies. Methods A total of 50 patients with SMTs who underwent endoscopic resection and were diagnosed by pathology and immunohistochemistry at Guangdong Provincial Corps Hospital of Chinese People’s Armed Police Forces from January 2018 to December 2022 were selected. All the patients were followed up and reexamined by colonoscopy three, six and twelve months after operation. Clinical symptoms, distribution of submucosal lesions in the colorectum, and endoscopic features of the patients were analyzed one by one, and the pathological results were summarized. Results Among the 50 cases, there were 22 cases of lipoma,8 cases of neuroendocrine tumors, and 20 cases of stromal tumors . Lipomas and stromal tumors were more commonly distributed in the colon, while neuroendocrine tumors were more common in the rectum and had the highest incidence of diarrhea. Forty cases of colorectal tumors were resected by endoscopic submucosal dissection (ESD), and 10 cases were resected by endoscopic mucosal resection (EMR). None of the patients had infection, delayed bleeding, or intestinal perforation after the operation. During the postoperative follow-up period of 6 to 20 months, there was no recurrence or metastasis in the patients. Conclusions SMTs present different features under endoscopic ultrasonography (EUS). EUS has an important guiding role on the differential diagnosis of SMTs and provides a safe and efficient strategy for endoscopic minimally invasive surgery.
