Robotic surgery has gained acceptance in oncological surgery. Its relevance in gastric cancer surgery is being examined. The study presents preliminary comparison of operative and postoperative outcome between robotic, laparoscopic and open gastrectomies for gastric adenocarcinoma.


Retrospective cohort of 85 consecutive patients that underwent total or partial gastrectomy for gastric adenocarcinoma at Rambam Hospital during 2012-2015. For each patient data was collected on basic demographic characteristics, BMI, operating room time(ORT), number of dissected lymph nodes(LN), length of hospitalization(LOH), intra and postoperative complications. Non parametric statistical tests MW and Kruskal-Wallis were used for group comparisons.


Study population included 55 patients after total gastrectomies, 10 of them robotic and 30 partial gastrectomies, 12 of them robotic. Age, gender and BMI were similar between patients who underwent robotic, laparoscopic and open procedures. Median length of hospitalization(LOH) for robotic total gastrectomy was 4.5 days and it was significantly shorter than both laparoscopic total gastrectomy(LTG) 7.0 days (p = 0.003) and open total gastrectomy(OTG) 9.0 days (p 


Robotic total and partial gastrectomies for gastric adenocarcinoma are associated with oncologically adequate lymphadenectomy and faster patient recovery, but longer operating time.
