【Abstract】 Objective To investigate the value of microwave tissue coagulation (MTC) technique in the surgical operation of partial splenectomy. Methods The partial splenectomy was performed in 12 rabbits by use of the MTC. Pathological and ultrastructural changes of the salvaged spleen tissues were observed under the electron microscope at 0 hour, 7 and 14 days, respectively, after the operation. Results Light microscopic examination demonstrated that the spleen tissues in the coagulation necrosis region could be categorized as a necrosis zone, a density zone and a marginal zone; Fiber proliferation growing into tissues could be seen on 14 days after the operation. Under the electron microscope, it was shown that the reticular cell was close to its normal condition with their mitochondrial crista still imperfect. Conclusion The damage to the salvaged spleen of rabbits after the surgical operation using MTC can be repaired in a short time. The surgical MTC technique is a valuable treatment method for partial splenectomy.更多还原
