Clinical Comparative Study of Laparoscopic D2 Radical Gastrectomy and Open Operation for Gastric Cancer

This study aims to evaluate the clinical curative effect of laparoscopic D2 radical gastrectomy for distal gastric cancer, investigate the advantages of this surgical method in clinic, and analyze its related complications. In the First Affiliated Hospital of Dali University, 51 laparoscopic and 51 open-radical operation patients were selected from April 2012 to August 2016. These patients were compared under the following parameters: incision length, intra-operative blood loss, recovery time of postoperative intestinal function, hospitalization duration, and postoperative leukocyte count on the first day. The incision length was 7.3 cm and 17.2 cm for patients in the laparoscopic group and open group, respectively (P < 0.01). Intraoperative blood loss was significantly lesser in the laparoscopic group than in the open group (202.3 ml vs. 405.5 ml, P < 0.01). Gastrointestinal function recovered more quickly in the laparoscopic group than in the open group (exhaust time: 3.5 days vs. 5.0 days, P < 0.01; solid food taking time: 5.0 days vs. 6.0 days, P < 0.01). Hospitalization duration was shorter in the laparoscopic group than in the open group (12 days vs. 16 days, P < 0.01). Postoperative leukocyte count on the first day was lower in the laparoscopic group than in the open group (8.08 × 10⁹ vs. 11.51 × 10⁹, P < 0.01).Laparoscopic D2 radical gastrectomy may be as beneficial as open operation for patients with gastric cancer, as previously suggested.
