[Comparison of early clinical outcomes between laparoscopic total gastrectomy and open total gastrectomy for early-stage gastric cancer].

Background/aims: Recently, laparoscopic distal gastrectomy has become one of the standard therapies for early gastric cancer. However, there are still some obstacles in performing laparoscopic total gastrectomy (LTG) as a standard therapy due to the difficulties in surgical techniques. We have performed LTG for patients with early gastric cancer in the upper portion of the stomach since 2010. In this study, we compared early clinical outcomes of LTG with those of open total gastrectomy (OTG) for patients with cT1N0 gastric cancer.
Methodology: We reviewed 69 patients who had gastric cancer of cStage IA between January 2010 and December 2013. We performed a comparative study of short-term clinical outcomes, quantity of dissected lymph nodes, and in-hospital costs between patients undergoing LTG (n=34) and those undergoing OTG (n=35).
Results: The clinical characteristics of patients were well matched in the LTG and OTG groups. The median operating time was significantly longer for the LTG group (p<.0001). The estimated blood loss was significantly reduced in the LTG group (p< 0.0001). The postoperative morbidity rate was 14.7% in the LTG group and 14.2% in the OTG group with no significant difference. There were no differences in the total cost for hospital stay between the LTG and OTG groups.
Conclusions: We were able to perform LTG safely and successfully for early gastric cancer in our institute. The total cost of the treatment was almost the same between LTG and OTG. We conclude that LTG is a potential alternative in the management of early gastric cancer.
