BACKGROUNDS/AIMS: Resection or enucleation is currently the treatment of choice for small pancreatic neuroendocrine tumors (NETs). Irreversible electroporation is a novel ablative method that is used for locally advanced pancreatic adenocarcinoma, but little data exists for its use for pancreatic NETs. We report an early experience of IRE for early pancreatic NETs. METHODS: Between April 2014 and March 2015, 3 patients with small (<2 cm) pancreatic NETs were treated with percutaneous IRE. RESULTS: There were no adverse effects during the procedure. Mean hospital stay was 2.6 days. All patients remained disease free on 12-19 months follow up. One patient developed recurrent pancreatitis with pseudocyst formation. CONCLUSIONS: IRE for small tumors of the pancreas is practical and may offer advantages over other thermal ablative techniques, since it preserves vital structures such as blood vessels, bile and pancreatic ducts. Further data regarding the long term disease free interval is required to establish efficacy.

The incidence of complications after liver resection is closely related to functional future liver remnant (FLR). The standard approach to augment FLR is surgical or radiological occlusion of the artery or portal vein on the tumor side. Associated liver partition and portal vein ligation for staged hepatectomy (ALLPS) has been introduced as an alternative method to augment FLR. It offers rapid and effective hypertrophy for resecting liver metastases. However, data regarding its application in patients with hepatocellular carcinoma (HCC) with a background of chronic liver disease are limited. Here we describe the use of ALPPS procedure to manage a large solitary HCC with a background of chronic liver disease. The rising incidence of HCC has increased the number of surgical resections in patients with advanced stage liver disease not considered for liver transplantation. We reviewed reported experience of ALPPS in established chronic liver disease and current therapeutic modalities for HCC on a background of chronic liver disease in patients with potential liver insufficiency where tumor burden is beyond liver transplant criteria.
