Summary Persistance of a large spontaneous splenorenal shunt (SRS) may result in graft failure in adult living donor liver transplantation (LDLT) because it reduces the effective portal perfusion to the partial liver graft by diversion of hepatotrophic portal flow into this hepatofugal pathway. We performed a prospective study to evaluate the efficacy of ligation of left renal vein (LRV) to prevent portal flow steal and the safety of this procedure to the renal function in adult LDLT patients with SRS. Between October 2001 and January 2005, 44 cirrhotic patients with large SRS underwent LDLT with ligation of LRV. Each patient received pre‐ and postoperative computed tomography and Doppler USG to assess the changes of collaterals and portal flow, as well as serial renal and liver function tests. Portal flow after ligation of LRV was statistically and significantly increased when compared with pre‐operative value (P = 0.001). Whereas four patients (9.1%) demonstrated sustained, elevated serum creatinine levels after operation, the renal function tests returned to normal in 40 patients. All patients recovered with satisfactory regeneration of the partial liver graft and there was no procedure‐related permanent renal dysfunction. In conclusion, ligation of LRV to prevent a ‘portal steal phenomenon’ seems to be a safe and effective graft salvage procedure for large spontaneous SRS (>10‐mm diameter) in adult LDLT.
Sarcomatous change has been rarely observed in hepatocellular carcinoma (HCC), but it is usually associated with very aggressive tumor behavior and widespread metastasis. To assess the impact of sarcomatous changes, we analyzed the outcomes of 15 patients with sarcomatous HCC after resection (n = 11) or liver transplantation (LT) (n = 4). No imaging findings characteristic of sarcomatous changes were observed. According to modified pathological tumor-node metastasis staging, the HCC lesions were classified as stage II in five patients, stage III in six, stage IVa2 in two, and stage IVb in one. The Milan criteria were met in 7 of 15 patients, including 3 of 4 in the LT group. R0 resection was achieved in 9 of 11 resected patients, and their 3-year overall and disease-free survival rates were both 18.2%. In the LT group, 3-year overall and disease-free survival rates were 37.5 and 25%, respectively. In patients within the Milan criteria, 2-year overall survival rate was 25% after resection and 33% after LT, showing no prognostic difference. Extrahepatic metastasis as initial recurrence was detected in 80% after resection and 66.7% after LT. In conclusion, we found that the prognosis of patients with sarcomatous HCC was very unfavorable after either resection or LT and that, except for liver biopsy, no diagnostic method could distinguish between sarcomatous and ordinary HCC. Vigorous postoperative systemic surveillance may be helpful for timely detection and treatment of localized metastases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
