The application of laparoscopic splenic hilar lymphadenectomy in the treatment of upper gastric cancer / 中华内分泌外科杂志

ABSTRACT

Objective:To evaluate the efficacy and safety of laparoscopic spleen-preserving splenic hilar lymphadenectomy through endovascular arch approach for superior gastric cancer.Methods:From Oct. 2018 to Feb. 2019, 20 cases of upper gastric cancer underwent laparoscopic total gastrectomy in Gastrointestinal Surgery Ward 1 of Yantai Yuhuangding Hospital. The splenic hilar lymph nodes were dissected by endogastric omentum vascular arch approach. The total operation time, intraoperative bleeding volume, operation time and bleeding volume of splenic hilar lymph nodes dissection, total number of lymph nodes and metastatic lymph nodes, number of splenic hilar lymph nodes and metastatic lymph nodes, postoperative exhaust time, first feeding fluid time and postoperative hospital stay time, and postoperative complications such as abdominal infection, anastomotic leakage, pulmonary infection, incision infection and bleeding were recorded. The complications of splenic hilar lymph node dissection were bleeding, conversion to laparotomy, splenic ischemia and splenic necrosis. One year after operation, follow-up was carried out by telephone and outpatient.Results:Laparoscopic total gastrectomy and splenic hilar lymph node dissection were successfully performed in all cases. The total operation time ranged from 200 to 268 min, with an average of (240.8±31.7) min, intraoperative bleeding volume of 50 to 200 ml, with an average of (90.4±43.8) ml; the time of splenic lymph node dissection was (18.5±4.0) min; the amount of splenic lymph node dissection bleeding ranged from 5 to 20 ml, with an average of (10.2 ± 5.8) ml; the number of total lymph nodes dissection was 25 to 58, with an average of 37.68±3.89 and the number of metastatic lymph nodes 4.31±2.54; The number of splenic lymph nodes was 2 to 10, with an average of 3.51± 1.79; The number of metastatic lymph nodes was 0 to 4 lymph nodes, with an average of 0.98±1.19. The average time of anal exhaust was (3.5±1.9) days, the time of fluid intake was (4.5±1.7) days, and the postoperative hospital stay was (7.5±1.5) days. Postoperative complications were as following one case had abdominal infection, one had pulmonary infection, one had anastomotic leakage and there were no complications related to splenic hilar lymph node dissection such as conversion to laparotomy, splenic ischemia or splenic necrosis. There was no recurrence or metastasis of the tumor and no death occurred one year after the operation.Conclusion:Laparoscopic spleen-preserving splenic hilar lymphadenectomy via endovascular arch approach is safe and effective.
