Eighteen normal apparently healthy adult dogs of both sexes-were used in this study. The animals were divided into 3 groups (each of 6 dogs). Under general anaesthesia (Thiopental Sodium) the spleen was exposed and some techniques for partial splenectomy were des cribed. In the first group the splenic capsule was closed with simple interrupted sutures using 4/0 chromic catgut. In the second group, a piece of gelfoam was used. In the third group a piece of omentum was used. Three dogs of each group were sacrificed after one, two and three week.
In the third group where the omentum was used, it was proved that the repair was greatly facillated to a great extent.
