Tumor renal con invasión hepática: aportación de un nuevo caso y revisión de la literatura

A safe combined nephrectomy and right lobectomy using the liver hanging maneuver for huge renal cell carcinoma directly invading the right lobe of the liver: report of a case

We herein discuss a patient who underwent simultaneous combined right nephrectomy and right lobectomy of the liver. A 64-year-old male was diagnosed with a huge right renal cell carcinoma (RCC), 13 cm in diameter, which was invading directly into the right hepatic lobe. This type of RCC has been rarely reported, and an anterior approach using the liver hanging maneuver was extremely useful during hepatic parenchymal dissection. The liver parenchymal dissection was performed prior to mobilization of the liver, because the mobilization of the right lobe of the liver was impossible. During the hepatic parenchymal resection, the liver was suspended with the tape and transected, and thereafter, retroperitoneal dissection, nephrectomy and right lobectomy of the liver were completed. The patient was discharged from the hospital on the 12th postoperative day with an uneventful clinical course. The anterior approach using the liver hanging maneuver during hepatic parenchymal resection can be safe and feasible for huge RCC invading the right hepatic lobe.

Partial nephrectomy and enbloc liver resection using a bipolar radiofrequency device for renal cell carcinoma invading the liver

A 66-year-old man presented with right- sided abdominal pain. Ultrasound, CT and MRI scans showed a right renal mass arising from the upper pole with direct involvement of the right lobe of the liver. Biopsy confirmed renal cell carcinoma. After Multi Disciplinary Team (MDT) discussion, right partial nephrectomy with enbloc resection of segments VI and VII of the liver was performed with the help of intraoperative ultrasound scan and the Habib 4X bipolar radiofrequency device. Apart from symptomatic collection, which was drained radiologically, the patient made a good recovery. The patient developed recurrence at the resection margin but is in remission following chemotherapy at 12 months.

Combined nephrectomy and major hepatectomy: indications, outcomes, and recommendations

BACKGROUND

Simultaneous nephrectomy with major hepatectomy (NMH) is uncommon. We reviewed our experience with NMH.

STUDY DESIGN

Records of patients who underwent NMH at Emory Hospital between January 1995 and May 2008 were examined. Patients undergoing resection of three or more liver segments at the same setting as a total nephrectomy were included. Indications and outcomes were assessed.

RESULTS

Twenty patients underwent NMH. Mean (+/- SD) age was 59.9+/-12.8 years, 6 (30%) were women, and 15 (75%) presented with comorbidities. Most kidney neoplasms were renal cell carcinomas of the right kidney (n=16, 80%) with a mean diameter of 10.0+/-6.1 cm. Eight patients (40%) also underwent thrombectomy for inferior vena cava tumor thrombus. The most common indications for hepatectomy were direct liver invasion in eight patients (40%) and distant hepatic metastases in nine (45%); liver tumors were 4.2+/-3.3 cm (mean +/- SD) in diameter. Mean (+/- SD) operative time was 8.3+/-2.6 hours. Liver resections included 15 (75%) right hepatectomies and 5 (25%) left hepatectomies. In all cases, tumor negative hepatic margins were achieved. Median operative blood loss was 1,700 mL (range 200 to 8,000 mL). Ten patients (50%) suffered complications in the postoperative period; three of these suffered major complications, resulting in one perioperative death (5%). Mean hospital stay was 12+/-8.8 days. Overall survival was 25 months (range 0 to 34 months).

CONCLUSIONS

In this large series of nephrectomy with simultaneous major hepatectomy, morbidity and mortality were acceptable. In specialized centers NMH may be considered in properly selected patients for combined resection for synchronous neoplasms of the kidney and liver.
