Abstract:Objective:To investigate effects of surgery frequency on the laparoscopic radical gastrectomy learning curve. Methods: A retrospective analysis of the laparoscopic radical gastrectomy by the same physician group Ⅰ and Ⅱ,respectively,from January 2008 to June 2010 (n = 100) and from January 2008 to January 2011(n = 90),the average monthly surgery rate was 3.33 and 2.50. Ⅰ group was divided into four phases (A,B,C,D),each phase of 25 cases,Ⅱgroup divided into six phases (E,F,G,H,I,J),each phase of 15 cases. Operative time,blood loss,postoperative hospital stay,complications,laparotomy number,number of lymph node dissection were compared between all groups. Results: As for four phases,the operative time and blood loss of C,D groups were significantly less than A,B phases. For six phases,the operative time and blood loss of I,J were significantly less than E,F,G,H phases,the number of lymph node dissection,complications,postoperative hospital stay and rate of transit laparotomy of each phase were not significantly different. The surgical time of 100 cases from Ⅰ group,was significantly less than 90 cases of Ⅱ group,the blood loss of patients in Ⅰ group was significantly less than the Ⅱ group,the difference of the number of lymph nodes and transit laparotomy rate and surgical complications between the two groups has no statistical significance. Conclusion: A shorter learning curve will be getten by increasing the surgery frequency appropriately,and benefit the understanding of the laparoscopic radical gastrectomy.
