ObjectiveTo survey the feasibility of laparoscopic high ligation for pediatric inguinal hernias by performing the surgery on rabbit models.
MethodsLaparoscopic high ligation was operated on 32 healthy New-Zealand male rabbits. Eight random rabbits were observed under laparoscope on the 7th, 15th, 30th, and 60th days after operation, and the anti-tension strength at the instant when hernial inner ring cracked was measured. Repair regions were resected. After HE-staining, the syzygial status of the repair regions were checked.
ResultsNone of the rabbits died during the research with no such complications as ankylenteron intestinal obstruction or hernia relapses after surgery. The anti-tension strength by the inguinal regions of the experimental rabbits after surgery on the 7th, 15th, 30th, and 60th days was respectively (42.69±6.98), (69.31±6.52), (102.64±7.91), and (106.53±7.54) mm Hg (1 mm Hg=0.133 kPa). As for the pathological section observation, the agglutination of the repair region was consistent with reparative process of chronic nonbacterial inflammation.
ConclusionThe operation of laparoscopic high ligation for repairing inguinal hernia on rabbits is safe and reliable.
