Evaluation of the effect of different anesthesia methods in endoscopic submucosal dissection of right hemicolon laterally spreading tumors with diameters＞3 cm
Objective To analyze the efficacy and safety of endoscopic submucosal dissection(ESD)in the treatment of LST with diameters＞3 cm in the right hemicolon under different anesthesia methods.Methods 166 patients with right half colon lateral tumor(LST)with diameters＞3 cm who received ESD treatment from July 2017 to October 2021 were retrospectively analyzed,and different anesthesia methods,postoperative complications and perioperative management were analyzed.Results ESD under tracheal intubation and general anesthesia was more effective than intravenous anesthesia in the treatment of right colon LST with diameters＞3 cm.There were no significant differences in the positive rate of resection margin,enbloc resection rate,curative resection rate and postoperative complication rate.Conclusion There is no significant difference in short-term efficacy and safety between intravenous anesthesia and endotracheal intubation for endoscopic submucosal dissection of right half colon lateral tumor with diameters＞3 cm,but endotracheal intubation can make ESD treatment more efficient.
