Endoscopic submucosal dissection in patients with high grade intraepithelial neoplasia and/or early cancer of remnant stomach after partial gastrectomy / 中华消化内镜杂志

ABSTRACT

Objective To evaluate the feasibility,safety and efficacy of ESD for precancerous lesions and early cancer of remnant stomach after partial gastrectomy.Methods ESD was performed in 11 cases of high grade intraepithelial neoplasia/early cancer of remnant stomach.The short-term and long-term indices including time of procedure,complication,En Bloc resection rate,R0resection rate,local recurrence rate as well as lymph node metastasis were recorded and analysed.Results ESD was completed in all patients with only one case of delayed massive bleeding which was controlled by endoscopy successfully.Average procedure time,En Bloc resection rate,R0 resection rate were 85.5 minutes,100％ and 90％,respectively.No local recurrence or lymph node metastasis was detected during post-ESD surveillance (15 ～ 51 months).Conclusion High grade intraepithelial neoplasia and early cancer of remnant stomach after partial gastrectomy might be indication for ESD because of its safety and definite effect.Additionally,careful management of the fibre tissue is the key to procedure success.
