Effect of minimally invasive surgery on lymphadenectomy in patients with adenocarcinoma of esophagogastric junction / 中国内镜杂志

ABSTRACT

Objective To investigate the effect of laparoscopic lymphadenectomy in patients with adenocarcinoma of esophagastric junction (AEG).Methods 105 patients with AEG underwent open or laparoscopic surgery from June 2014 to September 2015 were enrolled in the study and divided into minimally invasive group (n = 70) and laparotomy group (n = 35). The baseline data, lymphadenectomy result and perioperative data were compared between the two groups.Results Total number of splenic hilar lymph nodes dissection in minimally invasive group was significantly more than that in laparotomy group (P 0.05). Operation time, intraoperative blood loss, length of incision, positive proximal margins rate, thoracoabdominal resection rate and spleen resection rate in minimally invasive group were significantly lower than that in laparotomy group, esophagus resection length was significantly bigger than that in laparotomy group (P 0.05).Conclusions Compared with open surgery, laparoscopic surgery is superior in splenic hilar lymph nodes dissection of AEG, with longer esophageal cutting distances, lower thoracoabdominal resection and spleen resection rate. It is safe and feasible, worthy of clinical promotion.
