Neoplastic hilar obstruction to the liver outflow presents a unique challenge to the surgeon, wherein, the balance between a curative and possibly larger resection has to be achieved against a more conservative local resection. These are often technically demanding and have thus, far produced equivocal outcomes on both ends. The present case series is on 13 patients who presented with hilar obstruction. They all underwent resections with possible curative intent. The focus of our review is on the technical nuances and the strategies we used, intra- and peri-operatively to make resections possible in these patients, who at first look were deemed inoperable. Among the 13, 10 had hilar cholangiocarcinoma (CCA) while the others had a more benign diagnosis e.g., Hydatid disease. We did not encounter any peri-operative mortality in our series. Two of our patients had to be re-explored for intra-abdominal complications. Among the 13, we encountered two deaths. The rest of the patients are still on follow-up as of April 2016. Hilar CCA continue to be rare and challenging tumours for the Hepato Pancreato Biliary (HPB) surgeon to manage. Outlooks are currently changing as we try to resect bigger and more complicated hilar liver tumours with better results.
