Clinical efficacy of navigation of sentinel lymph node combined with endoscopic submucosal dissection in laparoscopic surgery for non curative treatment of early gastric cancer / 中华消化内镜杂志

ABSTRACT

Objective To explore the clinical efficacy of navigation of sentinel lymph node (SLN) combined with endoscopic submucosal dissection (ESD) for non curative treatment of early gastric cancer.Methods Clinical data of 9 cases with early gastric cancer treated with ESD from August 2015 to December 2015 were enrolled.The SLNs were explored by laparoscopy after nano carbon or indocyanine green(ICG) was injected under endoscopy.Then all stained nodes were resected by laparoscopy.Results The mean number of SLN were 2.75±1.50 in ICG group,which was significantly smaller than the number in nano carbon group(8.40±4.93) according to the laparoscopic pathology,so the accuracy of ICG was higher than that of nano carbon.But ICG performed better in development.The postoperative complications such as postoperative intestinal obstruction,enteritis and gastric paralysis were found in 5 patients of nano carbon group.But no serious complications after operation were found in patients of ICG group.Conclusion Application of ICG can help avoid the excessive removal of tissue,and reduce the incidence of complications.ICG,as a new type of tracer for early gastric cancer,shows good application prospects.
