Abstract:
Objective:To disiuss the application of liver free technique in renal cell carcinoma patients with Mayo Ⅱ-Ⅳ tumor thrombus.Methods:The clinical data of renal cell carcinoma patients with MayoⅡ-Ⅳ IVC tumor thrombus in our hospital from January 2014 to December 2019 were retrospectively analyzed. 25 patients underwent right part of liver or hepatic portal part dissection via open abdominal approach. There were 20 males and 5 females, aged 45-74 years (mean 61±6 years). All patients underwent urinary tract CTU or MRU examination, vena cava enhanced magnetic resonance angiography.There were left 8 cases, right 17 cases; the median length of tumor was 7 cm (3.6-12.1 cm). There were 1 case of Mayo grade Ⅱ tumor thrombus, 7 cases of Mayo grade Ⅲ tumor thrombus, and 17 cases of Mayo grade Ⅳ tumor thrombus. There were 7 cases of distant metastasis, including 6 cases of lung metastasis and 1 case of bone metastasis. After multi-disciplinary consultation (MDT), 19 patients underwent radical nephrectomy and 6 patients underwent tumor reducing nephrectomy. During the operation, the ligaments around the liver were completely dissociated and the space between the liver and kidney was opened. The bare area of the liver was fully dissociated, to expose the inferior vena cava. For Mayo grade Ⅳ tumor thrombus, 11 cases were treated with free diaphragmatic thrombus removal without thoracotomy, and 6 cases were treated with open chest cardiopulmonary bypass.Results:The median operation time was 444(258-694)min, the median intraoperative blood loss was 2 000(250-10 000)ml, and the median value of suspended red blood cell transfusion was 1 300(400-10 400)ml. The median postoperative hospital stay was 10(4-25)days.15 patients (60%) had postoperative complications, including 8 cases of liver injury, 5 cases of respiratory complications, 4 cases of kidney injury, 3 cases of anemia, 3 cases of infection and 1 case of thrombosis. Three patients died during perioperative period.Conclusions:The application of total liver free technique might obtain good exposure of surgical field, effectively control the hemorrhage of inferior vena cava, which is helpful for safe resection of tumor.
