BACKGROUND: Caudate lobectomy is now considered to be the most appropriate surgical treatment for benign tumors in the caudate lobe. But how to resect the caudate lobe safely is a major challenge to current liver surgery and requires further study. This research aimed to analyze the perioperative factors and explore the surgical technique associated with liver resection in hepatic caudate lobe hemangioma.
METHODS: Eleven consecutive patients with symptomatic hepatic hemangiomas undergoing caudate lobectomy from November 1990 to August 2009 at our hospital were investigated retrospectively. All patients were followed up to the present.
RESULTS: In this series, 9 were subjected to isolated caudate lobectomy and 2 to additional caudate lobectomy (in addition to left lobe and right lobe resection, respectively). The average maximum diameter of tumors was 9.65±4.11 cm. The average operative time was 232.73±72.16 minutes. Five of the 11 patients required transfusion of blood or blood products during surgery. Ascites occurred in l patient, pleural effusion in the perioperative period in 1, and multiple organ failure in l on the 6th day after operation as a result of massive intraoperative blood loss, who had received multiple transcatheter hepatic arterial embolization preoperatively. The alternating left-right-left approach produced the best results for caudate lobe surgery in most of our cases. All patients who recovered from the operation are living well and asymptomatic.
CONCLUSIONS: For large hemangioma of the caudate lobe, surgery is only recommended for symptomatic cases. Caudate lobectomy of hepatic hemangioma can be performed safely, provided it is carried out with optimized perioperative management and innovative surgical technique.
