Introduction: At present, the main treatment of gastric cancer is surgical resection combined with radiotherapy and chemotherapy, the most important part of which is radical gastrectomy. Laparoscopic radical gastrectomy for advanced gastric cancer is difficult to operate, and whether it can achieve the same curative effect with the laparotomy is still controversial.
Materials and methods: This study retrospectively analysed the clinical data of 269 gastric cancer patients surgically treated by our medical team from May 2011 to December 2015 for comparative analysis of the clinical efficacy of laparoscopic-assisted radical gastrectomy and traditional open radical gastrectomy.
Results: The laparoscopic surgery group had longer duration of surgery, less intra-operative blood loss, shorter post-operative exhaust time, shorter post-operative hospital stay and shorter timing of drain removal. The average number of harvested lymph nodes in the laparoscopic surgery group was 22.9 ± 9.5 per case. And in the laparotomy group the average number was 23.3 ± 9.9 per case. The difference had no statistical significance. With the increase of the number of laparoscopic surgical procedures, the amount of intra-operative blood loss gradually decreases, and the duration of surgery is gradually reduced.
Conclusion: Laparoscopic radical gastrectomy is superior to open surgery in the aspects of intra-operative blood loss, post-operative exhaust time, post-operative hospital stay and timing of drain removal. With the number of laparoscopic radical gastrectomy cases increased, the duration of surgery is shortened and the amount of intra-operative blood loss will decrease.
