High Success Rate and Safety of Through-the-Needle ESD Knife

Retrospective study found a newly developed through-the-needle injection-capable electrosurgical knife achieved successful en-bloc resection in 82.1% of gastrointestinal lesions. Good safety profile and curative resection rates were observed, with a median ESD time of 1.0 hour. Notably, success rates were lower in patients with submucosal fibrosis. The study highlights the effectiveness of the new knife for endoscopic submucosal dissection procedures.
