Laparoscopic splenectomy for idiopathic thrombocytopenic purpura in a woman with situs inversus: Report of a Case

A 51-year-old woman with previously diagnosed situs inversus (SI) totalis was admitted to our hospital with nasal bleeding. Blood tests showed severe thrombocytopenia, with a platelet count of 1.9 × 104/mm 3 , and idiopathic thrombocytopenic purpura (ITP) was diagnosed. She was refractory to medical treatment, so we performed laparoscopic splenectomy (LS). The mirrorimage anatomy made the procedure difficult for the right-handed surgeon, so we modified the technique to enable it to be performed via an anterior approach through the subxiphoid area using the right hand, with an ultrasonic dissecting device and an endostapling device. The operation was performed safely, the patient recovered uneventfully, and her platelet count normalized. To our knowledge, there has been no other report of LS in a patient with SI; however, it can be performed safely with careful management.
