BACKGROUND: Staging laparoscopy (SL) is used to avoid resection failure and thus increase the curative resection rate. SL utilization in extra-hepatic biliary tumors (EHBT) is variable. METHODS: Data from 1090 patients with potentially resectable EHBT including gallbladder (GBC), distal (DC), and hilar (HC) subtypes were retrospectively collected from 10 academic centers (2000-2015). RESULTS: The SL utilization rate increased over time and was significantly higher in GBC than DC and HC...

BACKGROUND: The prevalence and characteristics of actual 5-year survivors after surgical treatment of hilar cholangiocarcinoma (HC) have not been described previously. METHODS: Patients who underwent resection for HC from 2000 to 2015 were analyzed through a multi-institutional registry from 10 U.S. academic medical centers. The clinicopathologic characteristics and both the perioperative and long-term outcomes for actual 5-year survivors were compared with those for non-survivors (patients who died within 5 years after surgery)...

This study assessed neuropeptide Y (NPY) expression in the hippocampus after long-term survival following traumatic brain injury (TBI) induced by controlled cortical impact (CCI) with or without the development of posttraumatic epilepsy (PTE). We hypothesized that following long-term survival after CCI, the severity of tissue injury and the development of PTE would correlate with the degree of hippocampal neurodegeneration as reflected by NPY+ and neuronal nuclear antigen (NeuN)+ cell loss. Adult Sprague-Dawley rats of 2-3 months of age were lesioned in the right parietal cortex and monitored for seizure activity by video and/or video-EEG...

Human hippocampal slice preparations from patients with temporal lobe epilepsy (TLE) associated with hippocampal sclerosis (HS) are excellent material for the characterization of epileptiform-like activity. However, it is still unknown if hippocampal regions as cornu Ammonis (CA) 1, CA3 and CA4, generate population epileptiform-like activity. Here, we investigated epileptiform activities of the subiculum, CA1, CA2, CA3, CA4 (induced by elevation of extracellular potassium concentration) and the dentate gyrus (induced with hilar stimulation and elevation of potassium concentration) from sclerotic hippocampi of patients with drug-resistant TLE...

OBJECTIVE: The maturation of adult-born granule cells and their functional integration into the network is thought to play a key role in the proper functioning of the dentate gyrus. In temporal lobe epilepsy, adult-born granule cells in the dentate gyrus develop abnormally and possess a hilar basal dendrite (HBD). Although morphological studies have shown that these HBDs have synapses, little is known about the functional properties of these HBDs or the intrinsic and network properties of the granule cells that possess these aberrant dendrites...

Tottering mutant mice carry a mutation in the pore-forming subunit (α1A) of CaV 2.1 (P/Q-type) voltage-gated calcium ion (Ca2+ ) channels resulting in reduced neuronal Ca2+ current density. We assessed male tottering mice for spatial learning using the Morris water maze. Tottering mice performed worse than wild type mice, suggesting abnormal hippocampal function. Because Ca2+ influx via voltage-dependent Ca2+ channels regulates neuronal survival and function, we assessed hippocampus volume and cell density using hematoxylin and eosin stained serial sections...

BACKGROUND: While surgery offers the best curative-intent treatment, many patients with biliary tract malignancies have poor long-term outcomes. We sought to apply a non-mixture cure model to calculate the cure fraction and the time to cure after surgery of patients with peri-hilar cholangiocarcinoma (PHCC) or gallbladder cancer (GBC). METHODS: Using the Extrahepatic Biliary Malignancy Consortium, 576 patients who underwent curative-intent surgery for gallbladder carcinoma or peri-hilar cholangiocarcinoma between 1998 and 2014 at 10 major hepatobiliary institutions were identified and included in the analysis...

BACKGROUND: Biliary strictures at the hilum of the liver arise from heterogeneous etiologies. The majority is malignant entities, but some may have benign etiologies. It is difficult to distinguish between malignant and benign biliary strictures preoperatively. It has been reported that 5~15 % of preoperative diagnoses of hilar cholangiocarcinoma turn out to be benign lesions or even other types of malignancies. Primary non-Hodgkin's lymphoma of the extrahepatic bile duct is very rare, with only a few cases reported as mucosa-associated lymphoid tissue (MALT) lymphoma arising from the hepatic duct bifurcation...

Cholangiocarcinoma is a rare tumor originating in the bile ducts, which, according to their anatomical location, is classified as intrahepatic, extrahepatic and hilar. Nevertheless, incidence rates have increased markedly in recent decades. With respect to tumor biology, several genetic alterations correlated with resistance to chemotherapy and radiotherapy have been identified. Here, we highlight changes in KRAS and TP53 genes that are normally associated with a more aggressive phenotype. Also IL-6 and some proteins of the BCL-2 family appear to be involved in the resistance that the cholangiocarcinoma presents toward conventional therapies...
