METHODS The study was approved by the ethics committee of the Second Affiliated Hospital Zhejiang University School of Medicine(SAHZU). From April 2004 to July 2014, 20 patients were enrolled who underwent anatomic isolated caudate lobectomy at SAHZU. Clinical and postoperative pathological data were analyzed. RESULTS Of the total 20 cases, 4 received isolated complete caudate lobectomy(20%) and 16 received isolated partial caudate lobectomy(80%). There were 4 caseswith the left approach(4/20, 20%), 6 cases with the right approach(6/20, 30%), 7 cases with the bilateral combined approach(7/20, 35%), 3 cases with the anterior approach(3/20, 15%), and the hanging maneuver was also combined in 2 cases. The median tumor size was 5.5 cm(2-12 cm). The median intraoperative blood loss was 600 m L(200-5700 m L). The median intra-operative blood transfusion volume was 250 m L(0-2400 m L). The median operation time was 255 min(110-510 min). The median post-operative hospital stay was 14 d(7-30 d). The 1-and 3-year survival rates for malignant tumor were 88.9% and 49.4%, respectively. CONCLUSION Caudate lobectomy was a challenging procedure. It was demonstrated that anatomic isolated caudate lobectomy can be done safely and effectively.展开更多

This study was undertaken to improve operative techniques and results by a new anatomical method of caudate lobectomy. METHODS: Clinical data of 16 patients who had had caudate lobectomy for the liver from January 1996 to November 2004 were retrospectively analyzed. The third porta hepatis anatomical method was performed in all 16 patients. Operative time, intraoperative blood loss, postoperative complications were recorded. The 1-, 3-, and 5-year survival rates of 13 patients with caudate lobe carcinoma were followed up. Anatomical status, operative routes, operative procedures, liver blood supply were evaluated. RESULTS: The operation was successful in the 16 patients. The operative time was 255±70 minutes and blood loss 740±402 ml. None of the patients died from massive bleeding during the operation, nor did complications such as biliary fistula and liver failure occurred. In 13 patients with malignant tumor, 7 died from recurrence and metastasis of the tumor and the other 6 are still alive at the end of follow-up. One patient has survived for 6 years. The 1-, 3-, and 5-year survival rates in the 13 patients were 83.9%, 58.7% and 39.2%, respectively. CONCLUSION: Caudate lobectomy by the third porta hepatis anatomical method can improve operative effect and increase the resection probability for solitary tumor in the caudate lobe.展开更多
