Comparison analysis of two different types of endoscopic resection procedures in small gastric subepithelial tumours originating frommuscularis propria

Abstract

Background

For small gastric subepithelial tumours originating from the muscularis propria, there is no uniform standard for selecting the best endoscopic resection method.

Objective

To compare the efficacy and safety of endoscopic snare resection with a transparent cap (ESR-C) and endoscopic snare resection with an elastic band (ESR-EB) for small gastric subepithelial tumours originating from the muscularis propria to determine which method is more suitable for these tumours.

Methods

The data from small gastric subepithelial tumours originating from the muscularis propria treated from Jan 2020 to Dec 2022 were collected. A total of 34 eligible patients were enrolled. Sixteen of these patients were treated with ESR-C, and eighteen were treated with ESR-EB. The general clinical characteristics, tumour location, tumour size,growth pattern,operation time, complete resection rate, and complication rate were compared between the two groups.

Results

There was no difference in age, sex, tumour location, tumour size, growth pattern, or histological diagnosis after resection (p > 0.05). There was no significant difference in operation time, complete resection rate, or follow-up time (p > 0.05). Eight patients (50.5%) in the ESR-C group had complications (6 perforations and 2 bleeding), and 2 (11.11%) in the ESR-EB group had complications (2 perforations). There were significant differences between the two groups (p = 0.037). All perforations were successfully treated. No recurrence or metastasis was observed in either group during the follow-up period.

Conclusion

Both ESR-C and ESR-EB are effective and safe in treating small gastric subepithelial tumours originating from the muscularis propria. However, ESR-EB can significantly reduce the incidence of complications. ESR-EB is likely a better option for small gastric subepithelial tumours originating from the muscularis propria.
