The technique of right hepatic trisegmentectomy has been standardized for large tumors that involve the right lobe and extend into the medial segment of the left lobe. However, these tumors are deemed unresectable if they encroach across the falciform ligament into the left lateral segment. We report the technique of extended right trisegmentectomy in a patient with a large intrahepatic cholangiocarcinoma that involved the right lobe of the liver and extended into the medial and lateral segments of the left lobe. The resection was performed by using total hepatic vascular isolation and in situ hypothermic perfusion with modified histidine-tryptophan-ketoglutarate (HTK) solution into the left lateral segment. The biliary enteric anastomosis was constructed using a double hepaticojejunostomy to Segments II and III bile ducts. The procedure allowed safe parenchymal dissection with preservation of the blood supply to Segments II and III. Furthermore, in situ hypothermic perfusion protected the remnant liver from the deleterious effects of warm ischemia during parenchymal dissection and facilitated postoperative recovery. To the best of our knowledge, this is the first report of extended right trisegmentectomy for the treatment of intrahepatic cholangiocarcinoma in the Western literature.
CONTEXT: Majority of the patients developing obstructive jaundice have an underlying malignancy. Identification of a benign pathology like heterotopic pancreas as an aetiology is uncommon and usually occurs only subsequent to a major operation. CASE REPORT: We report a case of heterotopic pancreas adjacent to the ampulla of Vater mimicking distal cholangiocarcinoma. A 47-year-old patient presented with abdominal pain and obstructive jaundice. ERCP demonstrated a distal common bile duct stricture suspicious of cholangiocarcinoma. He underwent a pylorus-preserving pancreaticoduodenectomy. Histology showed a nodule of heterotopic pancreatic tissue adjacent to the ampulla. CONCLUSION: We have reviewed the literature on heterotopic pancreas of the periampullary region presenting with biliary obstruction. This is a rare entity and remains difficult to diagnose, despite advances in radiological and endoscopic imaging techniques. For symptomatic patients with an established diagnosis of periampullary heterotopic pancreas, local excision may be sufficient. However, in the absence of unequivocal imaging or histological confirmation of benign pathology, and when there is a suspicion of underlying malignancy, pancreaticoduodenectomy may be the only treatment option, as in this case.
Malignant liver tumors are either originating from the liver, such as the primary liver tumors hepatocellular carcinoma and the cholangiocellular carcinoma, or metastases from extrahepatic malignancies. Apart from surgical procedures (resection, liver transplantation) percutaneous local-ablative (ethanol injection, radiofrequency thermal ablation as well as radiation therapy) and transarterial interventions are non-surgical therapeutic options. While these regional therapies have been shown in randomised controlled studies to be effective for hepatocellular carcinoma, their therapeutic efficacy in cholangiocellular carcinoma and liver metastases has not been shown. In the following we will summarize the regional therapeutic options in primary and secondary liver tumors.
