抄録

We removed an elastofibroma dorsi by using the applied wound retractor (Alexis) in a 76-year-old woman. The patient was seen at the hospital because of a right dorsal tumor. A tumor was palpated inferiorly to the right scapula on abduction of the right shoulder joint, but was not palpated on the intermediate position. The tumor was elastic-hard and immovable, and had a smooth surface. There was no tenderness. CT scan revealed an about 5-cm tumor in the inner side of inferior angle of the scapula. Percutaneous needle biopsy gave the most likely diagnosis of elastofibroma. A skin incision about 6cm in length was made on her right side under general anesthesia. The latissimus dorsi muscle was separated off and oppressed forward by using Alexis. Separating off the lower layer of the greater rhomboid and anterior serratus muscles, the Alexis was placed under the lower layer and the operative field was developed. All the latissmus dorsi, greater rhomboid, and anterior serratus muscles were preserved, and the tumor was removed. There was no invasion into the surrounding organs, but we had great difficulties in separation from a part of periosteum of the 6t5 rib. The removed tumor was 56×45×15mm in dimension, grayish white in color, and solid. The histological diagnosis was elastofibroma. The patient's postoperative course was uneventful without any complications. In operation the Alexis was very helpful in protecting the wound edge and developing the surgical field.
