AIM: To reduce the risk of complications related to @entity5848 ( @entity5848 ) using knives, we developed a new grasping-type scissors forceps (GSF) that can grasp and incise the target tissue using electrosurgical current. The aim of the present study was to evaluate the efficacy and safety of @entity5848 using GSF for the @entity356 and @entity652 . METHODS: @entity5848 using GSF was carried out on 35 consecutive @entity1 with early @entity356 or @entity652 who had preoperative EUS diagnoses of @entity5 without lymph node involvement. Therapeutic efficacy and safety were assessed. RESULTS: All lesions were treated easily and safely without unexpected incision. The mean size of @entity5 and resected specimens was 15.6mm and 32.7mm, respectively. Curative en-bloc resection rates according to @entity5 size and location were 96% (26/27) in @entity5  <=20mm, 100% (8/8) in @entity5 >20mm, 100% (18/18) of @entity5 in the lower portion, 100% (8/8) of @entity5 in the middle portion, 89% (8/9) of @entity5 in the upper portion, and 97% (34/35) overall. The mean operating time according to @entity5 size and location was 93.4min in @entity5  <=20mm, 140min in @entity5 >20mm, 77.6min for @entity5 in the lower portion, 113.4min for @entity5 in the middle portion, 148.6min for @entity5 in the upper portion, and 104.1min overall. No @entity3816 occurred, and @entity86 was seen in 3% (1/35). CONCLUSIONS: @entity5848 using GSF allows simple and safe en-bloc resection of early @entity356 or @entity652 irrespective of @entity5 size and location.
