Abstract

Abstract:

Objective

To evaluate the effect of lymph node examination on the number of retrieved lymph nodes in carbon nanoparticles-guided 3D laparoscopic radical gastrectomy.

Methods

Qualified participants were randomized into non-examined or examined group. Sub-group analysis according to different pathological stage or type of radical gastrectomy were conducted. The number of retrieved lymph nodes were compared between groups. Perioperative safety and survival during follow-up period were compared as well.

Results

A total of 147 patients including 58 cases in non-examined group and the other 89 cases in examined group were collected. Baseline was similar between groups. The overall duration of operation was (214.8±55.6)min, intraoperative bleeding was (128.7±106.0)ml, postoperative complication rate was 7.5%, secondary operation rate was 1.3%, postoperative hospitalization was (11.5±3.7)d, and all were survival during (15.1±6.9) month follow-up period. The safety was similar between two groups. Lymph node examination can significantly improve the number of retrieved lymph nodes for stage Ⅰ gastric cancer (29.0±12.3) vs. (24.1±7.8), P=0.04) and total radical gastrectomy (31.3±11.2) vs.( 25.1±7.6), P=0.02).

Conclusions

Lymph node examination can improved the number of retrieved lymph nodes in stage I gastric cancer and total radical gastrectomy in carbon nanoparticles-guided 3D laparoscopic radical gastrectomy.
