[Partial splenic resections and Nd-YAG laser]

Eleven partial splenectomies are performed in pigs. Simultaneous section and hemostasis are obtained with continuous 80 W power shoot. There is no hemorrhagic or septic complication and normal splenic weight is recovered in 5 months. Platelets elevation observed in post-operative. Platelets elevation observed in post-operative period returns to normal rate between 20th and 30th day. Acute cellular damage of cut splenic edge does not exceed 3 mm in thickness. Semi-thick and electron microscopic examination reveals at day 10 mitotic figures of lymphocytes (i.e. splenic regeneration) and at day 30 high density of mast cells and plasmocytes i.e. cellular biostimulation).
