Abstract
Background
No previous robotic studies present an equivalent surgical quality comparison in an experienced setting for gastric cancer. In addition, a reliable postoperative complication assessment is needed to accurately evaluate surgical outcomes.
Methods
After 20 cases of robotic-assisted gastrectomy (RAG), a total of 121 consecutive gastric cancer patients underwent gastrectomy (38 RAG vs 83 laparoscopic-assisted gastrectomy [LAG]) from February 2009 to November 2010 at the Department of Surgery, Korea University Anam Hospital, Seoul, Korea. The Clavien-Dindo (C-D) classification was used to classify surgical complications. The granulocyte-to-lymphocyte (G:L) ratio was analyzed to evaluate surgical stress.
Results
The baseline characteristics, with the exception of age, were similar. The mean total operation time for RAG (234.4 ± 48.0 min) was not significantly different than that for LAG (220.0 ± 60.6 min; P = 0.198). However, in obese patients, fewer lymph nodes were harvested by RAG (23.4 ± 7.0) than by LAG (32.2 ± 12.5, P = 0.006). Overall C-D complications were more common for RAG (47.3 vs 38.5 %), but the difference was not significant (P = 0.361). The mean hospital stay was similar for the 2 groups. Surgical stress as estimated by the G:L ratio was comparable between the 2 groups.
Conclusions
RAG performed by an experienced surgeon resulted in similar postoperative outcomes and complications to those of LAG. Assessment of operation time, C-D complication grade, and G:L ratio revealed that RAG is a practical and feasible alternative to LAG, with the possible exception of obese patients.
