- Abstract
Background & Aims: The most suitable procedure for resecting small-sized gastric neoplasms remains unclear. Endoscopic mucosal resection leads to non-curative resection owing to slippage of the snare, and technically difficult endoscopic submucosal dissection (ESD) is instrumentally uneconomical. A novel, cost-effective, multifunctional snare called SOUTEN is available as a hybrid ESD (h-ESD) device developed for facilitating ESD. This study aimed to assess the acceptability of h-ESD using the SOUTEN for resecting small-sized gastric neoplasms. Methods: This was a prospective observational study conducted at our single institution between March 2019 and March 2021. Fifty-seven consecutive patients who underwent h-ESD using SOUTEN for small-sized gastric neoplasms ≤15 mm involving adenoma and tubular-type mucosal carcinoma without ulceration were enrolled. The primary outcome was curative resection rate for h-ESD. Secondary outcomes were the rates of conversion to ESD, rate of total (h-ESD + ESD) curative resection, procedure time, rates of intra-and postoperative complications, and presence of additional knives excluding hemostatic forceps. Results: The curative resection rate of h-ESD was 89.5% (51/57). The total (h-ESD + ESD) curative resection rate was 94.7% (54/57). The mean procedure time was 21.2 (±16.5) minutes. One case of delayed bleeding occurred. Additional knives were applied in two cases. Conclusions: The cost-efficient h-ESD using SOUTEN can be an acceptable procedure for resecting smallsized gastric neoplasms.
