ARTICLE HIGHLIGHTS
Research background

Hand-assisted laparoscopic gastrectomy (HALG) is a popular operation in China, but some surgeons do not accept it as a minimal-access technique. 

Research motivation

If the safety and practicability of HALG can be confirmed by comparing with laparoscopic-assisted gastrectomy (LAG), HALG should be used as a minimal-access technique.

Research objectives

This research aimed to assess the safety and practicability of HALG by comparing the short-term outcomes of HALG and LAG.

Research methods

The electronic databases of EMBASE, PubMed, China National Knowledge Infrastructure, and Cochrane Library were thoroughly searched, and only randomized controlled trials (RCTs) comparing HALG and LAG were included.

Research results

This meta-analysis included five RCTs with 600 cases. Compared with LAG, HALG reduced surgery time, hospital duration, and overall postsurgical complications, and increased the number of retrieved lymphatic nodes and incision length.

Research conclusions

HALG is simpler and safer technique than LAG. HALG should be used as a minimal-access technique, especially in technologically undeveloped areas.

Research perspectives

It is important to evaluate the long-term survival of hand-assisted laparoscopic gastrectomy in the future.
