To explore the clinical effect and safety of modified D2 laparoscopic-assisted distal gastrectomy with a small incision (MLADG) for gastric cancer.

Clinical data of 90 cases of D2 laparoscopic-assisted distal gastrectomy were analyzed from March 2014 to December 2015. According to different operative methods, patients were divided into MLADG group (45 cases) and LADG group (45 cases). Statistical analysis were performed by using SPSS21.0 software. Measurement data such as Perioperative indicators and surgical indicators were represented as (±s) and were examined by using independent t test. Postoperative complications were analyzed by using χ² test. Kaplan-meier method was used for survival analysis. A P value of <0.05 was considered as statistical significant difference.

The amount of intraoperative bleeding, the duration of CO2 pneumoperitoneum, the time of ambulation, the time and blood loss during the dissection of NO.6 lymph nodes in MLADG group were significantly better than those in LADG group respectively (P<0.05); There was no significant difference between two groups in terms of postoperative complications(15.6% vs. 13.3%), P>0.05. There was no significant difference between two groups in terms of the 3-year cumulative survival rate of 68.9% (31/45) in MLADG group VS. 66.7% (30/45) in LADG group (P>0.05).

MLADG is safe and feasible, in line with the principle of radical resection of distal gastric cancer. Compared with LADG, MLADG has less total operation time, less time of the dissection of NO.6 lymph nodes with less blood loss, which is worthy of clinical promotion.
