ObjectiveTo compare the clinical therapeutic effect and application value of endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) in the treatment of digestive tract tumor. MethodsA total of 60 patients with digestive tract tumor were selected, among which, 30 patients received EMR were enrolled as EMR group, while the other 30 patients received ESD, whose general data were equilibrium to those of the EMR group, were enrolled as ESD group during the same study period. The total tumor resection rate, complete resection rate, operation duration, intraoperative bleeding volume, hospital stay, the prevalence of complications, and lesion residue conditions 1 month after operation were compared between the two groups. ResultsCompared to the ESD group, the EMR group yielded lower total tumor resection rate and complete resection rate, shorter operation duration, whereas greater intraoperative bleeding volume, longer hospital stays, and a lower postoperative incidence of complications (all P＜0.05). The residual rate of lesions 1 month after operation in the EMR group was higher than that in the ESD group, but there was no statistically significant difference between the two groups (P＞0.05). ConclusionBoth EMR and ESD have a good effect in the treatment of digestive tract tumor, with EMR superior to ESD in operation duration and complications control, while ESD superior to EMR in intraoperative bleeding volume, total resection rate of tumor, complete resection rate, and hospital stay. Hence, it is necessary to consider with the practical condition of patients when selecting surgical method in clinical practice.
