Abstract:
Objective:To investigate the efficacy and safety of endoscopic submucosal dissection (ESD) for the treatment of upper gastrointestinal lesions .Methods:IT knife and HOOK knife were applied in ESD for the treatment of 30 cases of upper gastrointestinal mucosal or submucosal lesions revealed by gastroscopy .The ESD procedure was conducted as follows .Firstly , 0 .9% sodium chloride solution was injected into the submucosa so as to elevate the mucosa on lesion .Secondly ,the mucosa around the lesion was pre‐cut .Thirdly ,the lesion was dissected completely from the surrounding connective tissue .Results:The diameters of the lesions ranged from 0 .8 to 4 .5 cm with mean of (2 .6 ± 1 .3) cm .As postoperative pathology confirmed , there was tumor residual on wound surface of 2 cases after ESD ,and they received extended resection .And the lesions of the other 28 cases were successfully resected by ESD .The success rate of complete dissection was 93 .3% (28/30) .The ESD procedure time (from fluid injection to complete dissection) ranged from 29 to 110 min ,with a mean of (48 ± 11 .2) min .The average amount of bleeding during operation was 45 mL and the bleeding was successfully stopped by electro‐coagulation ,argon plasma coagulation . One patient (aspirin was stopped 5 days before operation) suffered hemorrhage per‐diapedesin and recovered after conservative treatment .The bleeding rate of ESD was 3 .33% (1/30) .Perforation occurred in 3 cases during the ESD procedure ,and was closed with metallic endoclip .And no case was transferred to laparotomy .The perforation rate of ESD was 10 .0% (3/30) .After the operation ,16 cases were followed up .And the follow‐up period ranged from 3 to 6 months ,with a mean of (4 .5 ± 1 .2) months .The wound surfaces of 16 cases were healed ,and there was no residue or recurrence .Conclusions:The curative effect of ESD for the treatment of upper gastrointestinal lesions is reliable ,as it can not only wholly remove the large lesion ,but also provide with pathological proof .With ESD ,less pain ,faster rehabilitation ,and lower recurrent rate can be achieved for patients .
