- Background ALPPS is found to increase the resectability of primary and secondary liver malignancy at the advanced stage. The aim of the study was to verify the surgical and oncological outcome of ALPPS for intrahepatic cholangiocarcinoma (ICC). Methods The study cohort was based on the ALPPS registry with patients from 31 international centers between August 2009 and January 2018. Propensity score matched patients receiving chemotherapy only were selected from the SEER database as controls for the survival analysis. Results One hundred and two patients undergoing ALPPS were recruited, 99 completed the second stage with median inter-stage duration of 11 days. The median kinetic growth rate was 23 ml/day. R0 resection was achieved in 87 (85%). Initially high rates of morbidity and mortality decreased steadily to a 29% severe complication rate and 7% 90-day morbidity in the last 2 years. Post-hepatectomy liver failure remained the main cause of 90-day mortality. Multivariate analysis revealed insufficient future liver remnant at the stage-2 operation (FLR2) to be the only risk factor for severe complications (OR 2.91, p = 0.02). The propensity score matching analysis showed a superior overall survival in the ALPPS group compared to palliative chemotherapy (median overall survival: 26.4 months vs 14 months; 1-, 2-, and 3-year survival rates: 82.4%, 70.5% and 39.6% vs 51.2%, 21.4% and 11.3%, respectively, p amp;lt; 0.01). The survival benefit, however, was not confirmed in the subgroup analysis for patients with insufficient FLR2 or multifocal ICC. Conclusion ALPPS showed high efficacy in achieving R0 resections in locally advanced ICC. To get the most oncological benefit from this aggressive surgery, ALPPS would be restricted to patients with single lesions and sufficient FLR2.

- Background: Hand-assisted and retroperitoneoscopic techniques reduce the risk of bleeding and intra-abdominal complications in live donor nephrectomy (LDN). This study reports on our four-centre experience, development and learning curves from the first 413 LDN using a hand-assisted retroperitoneoscopic technique (HARS). Methods: The first 413 consecutive donors operated on using HARS were included in the study. Donor demographics, peri- and postoperative data, complications, and recipient outcomes have been compiled. The data was analysed as a whole and separately for each centre, looking at centre differences and learning curves over time. Results: Significant differences were found in donor demographics between centres for the variables: age, BMI, number of arteries, and side of operation. Mean operating time was 170.2 minutes, with significant differences between centres. Operating time was also significantly influenced by learning curves, Sex/BMI, and side of operation. Warm ischemia time differed significantly between centres and was influenced by centre-wise learning and number of arteries. Overall conversion rate was 2.4% and differed significantly between centres. There was no mortality and no intra-abdominal complications. Apart from the conversions and one pulmonary embolism, there were no major intra- or postoperative complications. Overall 3-month graft survival was 99%, with 96% immediate onset of function and 1% ureteral complications. Conclusions: The HARS technique reduces the risk of intra-abdominal complications. It can be implemented with excellent donor and recipient outcomes despite different population demographics and centre/surgeon-related tradition and experience. Based on our experience, we recommend the technique in order to increase the safety margin of LDN.
