ObjectiveTo study the clinical value of thermal biopsy forceps combined with snare-assisted traction in endoscopic submucosal dissection(ESD) treating stomach tumors.

MethodsThe clinical data of 120 stomach tumor patients treated with ESD were analyzed, and the patients were randomly divided into the observation group and control group(60 cases in each group).The observation group was treated with hot biopsy forceps combined with snare-assisted traction technique, and the control group was not treated with any assisted traction technique.The rate of one-time complete removing tumor, operation time, incidence rates of intraoperative bleeding and perforation, and postoperative following-up were compared between two groups.The clinical efficacy and safety in two groups were evaluated.

ResultsThe rate of one-time complete removing tumor in observation group was significantly higher than that in control group(P < 0.05).The operation time, intraoperative bleeding and incidence rate of complication in observation group were significantly lower than those in control group(P < 0.01).The difference of the postoperative pathology results between two groups was not statistically significant(P>0.05).

ConclusionsThe thermal biopsy forceps combined with snare-assisted traction has the advantages of convenient operation, less tissue damage and good traction effects, etc., which can effectively ensure the clear vision field of ESD operation, shorten the operation time, and reduce the incidence rates of intraoperative complications such as bleeding, perforation, lesion residue and tumor strapping into the chest and abdominal cavity.
