Infrared-contact coagulation of the spleen with an infrared-sapphire-coagulator was applied in two children with subcapsular hematoma and splenic cyst, thereby achieving complete and partial organ preservation, respectively. This method was also used for haemostasis following the dissection of a common liver in Siamese twins. Infrared-contact coagulation is a proper method for organ preservation in injuries or other pathological conditions of parenchymatous organs.
