Abstract
Demonstration of the possibility of successful removal of a subepithelial neoplasm of the rectum by endoscopic submucosal-intermuscular dissection (EPMD). In a 50-year-old patient, a colonoscopy in the department of endoscopic diagnostics and surgery in the middle ampullary rectum revealed a subepithelial neoplasm up to 0.5 cm in diameter, yellowish in color, and the mucous membrane above the neoplasm was unchanged. On instrumental palpation, the formation was difficult to shift, of a dense consistency, and the symptoms of a “tent” and “pillow” were negative. EPMD was performed.
The postoperative period was uneventful, and the patient was discharged on the 5th day after surgery.
Morphological conclusion: leiomyoma of the intrinsic muscle plate of the mucosa. Resected at the level of the inner muscle layer, the edges of the resection are intact.
