Abstract:
Objective To evaluate the surgical effects of laparoscopic pancreaticojejunostomy in pigs and investigate the learning curve. Methods A total of 40 porcine cases of laparoscopic pancreaticojejunostomy were performed by a single surgical team from September 2012 to February 2013.According to the operation sequence, pigs were divided into 4 groups with 10 in each group.For analyzing the efficacy of surgery in different stages, the operation time and efficacy of anastomoses were compared between these groups. Results The operation was finished successfully in all the 40 cases.There were statistical significances in operation time among the four groups.The group Ⅳ had significant shorter time (112.7 ±8.3) min than those in the group Ⅰ [(145.1 ± 16.6) min, q=9.154, P<0.05], the groupⅡ[(133.0 ±8.7) min, q=5.735, P<0.05], and the group Ⅲ[(137.2 ±9.0) min, q=6.922, P<0.05], respectively.There was no difference between the group Ⅱ and the group Ⅰ in operation time (q=3.419, P>0.05), so as to other groups.The results of anastomoses among the four groups were not significantly different (χ2 =0.586,P=0.900). Conclusions Laparoscopic pancreaticojejunostomy in pigs is feasible.The learning curve of the operation is about 30 cases.
