BACKGROUND Gastric cancer(GC)has high morbidity and ***,because GC has no typical symptoms in the early stages,most cases are already in the advanced stages by the time the symptoms appear,thus resulting in poor prognosis and a low survival *** submucosal dissection(ESD)can realize the early detection and diagnosis of GC and become the main surgical method for early ***,ESD has a steep learning curve and high technical skill requirements for endoscopists,which is not conducive to its widespread implementation and ***,a series of auxiliary techniques have been *** To evaluate the safety and efficacy of magnetic anchor technique(MAT)-assisted ESD in early *** This was an ex vivo animal *** experimental models were the isolated stomachs of pigs,which were divided into two groups,namely the study group(n=6)with MAT-assisted ESD and the control group(n=6)with traditional *** the total surgical time,incidence of surgical complications,complete mucosal resection rate,specimen size,and the scores of endoscopist’s satisfaction with the procedure reflected their feelings about convenience during the surgical procedure between the two *** magnetic anchor device for auxiliary ESD in the study group comprised three parts,an anchor magnet(AM),a target magnet(TM),and a soft tissue *** gastroscopic guidance,the soft tissue clip and the TM were delivered to the pre-marked mucosal lesion through the gastroscopic operating *** soft tissue clip and the TM were connected by a thin wire through the TM tail *** soft tissue clip was released by manipulating the operating handle of the soft tissue clip in a way that the soft tissue clip and the TM were fixed to the lesion *** vitro,ESD is aided by maneuvering the AM such that the mucosal dissection surface is *** The total surgical time was shorter in the study group than in the control group(26.57±0.19 vs 2
