Laparoscopic gastroesophageal junction cancer lymphadenectomy / 中华普通外科杂志

ABSTRACT

Objective To analyze laparoscopic lymphadenectomy and the safety of gastrectomy for gastroesophageal junction cancer.Methods From Jan 2011 to Dec 2012 72 gastroesophageal junction cancer patients were enrolled, including 46 patients in laparoscopic group, and 26 in open surgery group.Results There was no significant difference in the numgbers of lymph node dissection between the two groups and nor difference in the number of positive lymph node dissection.Esophagus resection length in open group was (2.0 ± 1.0) cm, while that was (3.0 ± 0.8) cm in laparoscopic group (t =0.471, P ＜ 0.001).5 (19％)patients in open group had positive margins compared to six in laparoscopic group (13％), x2 =0.491, P =0.483.7 patients in the open group underwent thoracoabdominal resection, while in laparoscopic group 3 patients did, x2 =5.781, P =0.016.Laparoscopic splenic hilar lymphnodes dissection harvested more lymph nodes (t =0.260, P =0.011).Laparoscopic gastrectomy used less operation time (t =0.237, P =0.021) experinced less blood loss (t =0.451, P ＜ 0.01) than open group.There was no difference in major complications between the two groups.Conclusions Laparoscopic splenic hilar lymphnodes dissection in gastroesophageal junction cancer surgery is superior to open surgery, with more lymph nodes harvested, longer esophageal cutting distances, lower incidence of thoracoabdominal surgery, shorter operation time, and less blood loss.
