120 female rabbits were studied, with a weight range from 2.400 to 3.100 g. with the purpose of evaluating the effect of the ligadure in the bottom of the appendix vermiformis of the rabbit and its action, from macroscopic and microscopic aspects, about this organ. The animals were, therefore, distributed in 2 groups of 60 animals called experiment and sham, and were subdivided in 3 sub-groups of 20 rabbits for each group which were called 24 h, 48 h, 72 h, 24 Sh, 48 Sh and 72 Sh, that corresponded to the observation period of 24, 48 and 72 hours. Its was verified the occurrence of both, macroscopic and microscopic appendicities in all rabbits from the experiment group on the 3 studied periods, with no significant differences between the groups, but observing the evidence, in all groups, of more onward appendicities. There was no alteration in the rabbits of the sham group. In statistic valuation there was significance in the reading of the appendix end diameter, evaluated at the beginning and in the end of the observation period in each group, when comparing the groups, however, there was no statistics significance. The evaluation of the macroscopic changes about adherence, appendix collor changes, peritonitis, necrosis, perforation and the microscopic changes weren’t significant on a statistics view. It follows that the obstruction in the bottom of the appendix vermifomis of the rabbit induces to both, macroscopic and microscopic acute appendicities.
