Pure laparoscopic liver resection for giant liver hemangioma with extrahepatic growth based on preoperative 3-dimensional simulation: A case report

Background Performing laparoscopic liver resection for giant hemangiomas is challenging, and careful preoperative planning is essential. Controlling intraoperative bleeding and handling surgical instruments within a limited workspace is necessary. Case presentation In the present case, the patient was a 38-year-old woman diagnosed with a 16-cm giant liver hemangioma in segment 5/6, with extrahepatic growth. Preoperative three-dimensional simulations for port placement and the laparoscopic view from the left upper abdomen were performed to complete the pure laparoscopic liver resection. The laparoscopic resection was then safely performed on the same way. Conclusions Pure laparoscopic resection could be applied to giant hemangiomas with extrahepatic growth, and the preoperative three-dimensional simulation of port placement and the laparoscopic view might be helpful when the intraabdominal workplace is restricted.
