Objective To explore the clinical value of resection of small gastrointestinal stromal tumor(GIST) with transparent cap assisted band ligation. Methods The clinical data of 151 patients who underwent ligation of small GIST assisted with transparent cap in our hospital from February 2017 to February 2020 were retrospectively analyzed, and the complete resection rate, recurrence rate, and complication rate, operation time, hospitalization days and other indicators were analyzed. Results Among the 151 patients with small GIST, 91 cases were located in the fundus of the stomach, 53 cases were in the stomach body, and 7 cases were in the antrum of the stomach. All the lesions were completely resected with the aid of transparent cap. Among lesions of 150 cases, the envelopes were intact and no residue was seen by naked eyes and pathology examination, and 1 case was completely resected after 2 ligations. There were 3 cases of active bleeding, no delayed bleeding, and 105 cases of iatrogenic perforation during the operation. The maximum diameter of the perforation was about 1 cm. There were 3 cases of pneumothorax and mediastinal emphysema, 3 cases of localized peritonitis, and 4 cases of fever. After hemostasis, repair and symptomatic treatment under endoscopy, no case was transferred to surgical departmat during or after operation; the average operation time was (28.3±7.6) minutes, and the average hospital stay was (4.3±1.9) days. Pathological results showed there were 132 cases of very low-risk gastrointestinal stromal tumors and 19 cases of low-risk gastrointestinal stromal tumors. There was no sign of recurrence in the gastroscope during the follow-up. Conclusion The transparent cap assisted ligation resection of small GIST was simple, safe and effective, and had the value of clinical promotion.
