Abstract

BACKGROUND The curative surgical treatment of gastric cancer in the current laparoscopic surgical era relies on the surgeon's preference, technical difficulties, and concerns regarding outcome have led to the availability of totally laparoscopic distal gastrectomy (TLDG) and laparoscopic-assisted distal gastrectomy (LADG). A consensus on which of the two procedures is preferable is necessary. Therefore, the aim of this study was to evaluate the differences between LADG and TLDG in terms of surgical outcomes, postoperative recovery, pain, and complications. METHODS PubMed, Google Scholar, Medline, Embase, and Cochrane databases were explored up to 2017 to evaluate TLDG and LADG. Parameters including surgical outcomes, postoperative recovery, and postoperative complications were subjected to meta-analysis to calculate the odds ratio and weighted mean difference with 95% confidence intervals (c.i.). RESULTS Twenty-five studies (24 non-RCT and 1 RCT) with a total of 4562 gastric cancer patients were included in the meta-analysis. Under reconstruction-matched analysis, overall complications and anastomotic complications were similar for TLDG and LADG. Nevertheless, short-term outcomes such as blood loss, time to first soft diet, hospital stay, analgesic use, and CRP level were favourable for TLDG, while all other surgical outcomes showed no difference. CONCLUSIONS TLDG and LADG did not show significant differences in surgical outcomes and postoperative complications, including anastomotic-related morbidity. Therefore, decisive factors in selecting surgical procedures, which previously consisted of surgical outcomes, have been superseded by extra-surgical values such as cosmesis, economics, and patient's quality of life. These factors will be explored in a future multicentre prospective study (KLASS07 trial).
