A research article published in the September 28 issue of the World Journal of Gastroenterology addresses these issues of efficiency and safety. A research team led by Dr. Xiao-Dong Zhou from the First Affiliated Hospital of Nanchang University spent more than 15 years working with a cohort of 69 patients with gastrointestinal smooth muscle tumors (SMTs) who had accepted endoscopic examination and treatment. The large sample size allowed them to obtain results with high statistical significance and draw very reliable conclusions.
The main finding they reported is that endoscopic resection is a safe and effective treatment for SMTs with a base size 2 cm when the "pushing" or "grasping and pushing" technique is used and the pedunculated SMTs are resected by polypectomy. No severe complications developed during or after the procedure in any of the cases. Further, no recurrence was observed.
Another interesting finding is that the diagnostic accuracy of ordinary and "digging" biopsy techniques was 90.0% and 94.1%, respectively. Thus, the "digging" biopsy technique is a good option for the histologic diagnosis of SMTs. The investigators suggested that endoscopic resection is a safe and effective treatment for leiomyomas with a base size ĄÜ 2 cm and that patients should not worry about recurrence after endoscopic resection.
