In this report,a patient had a previous diagnosis of cholangiocarcinoma with an extended cholecystectomy. Three years later,he was evaluated for recurrent ascites. The patient had several large volume paracentesis, without evidence of malignant ***, endoscopic ultrasound(EUS)with fine needle aspiration (FNA)of both lymph and omental nodules was *** the lymph nodes were negative for malignancy, the omental nodule was interrogated with multiple antibodies and was found to be positive for neoplasia. EUS with FNA can safely be used in patients with cirrhosis to spare the patient invasive evaluation such as exploratory laparotomy(ex-lap)for diagnosis and staging of cholangiocarcinoma.

The cross section values of the^(71)Ga(n,γ)^(72)Ga reaction are measured,which are 9.14±0.81 mb and 5.74±0.50 mb at 2.15 and 3.19 MeV,*** detailed uncertainty propagation and covariance analysis are also ***^(7)Li(p,n)^(7)be reaction was used to generate the neutrons,and the neutron flux was normalized using the^(115)In(n,n′)^(115)In^(m)monitor *** measured cross section data are compared with the data available in the EXFOR database,the data obtained using nuclear reaction model codes EMPIRE-3.2 and TALYS-1.95,and also the evaluated nuclear data from ENDF/b-VIII.0 and jeff-3.1/*** comparison shows that our result at 3.19 MeV is in good agreement with those of EMPIRE-3.2 and jeff-3.1/*** there are no other measurements available at3.19 MeV,our data could not be compared with literature data at 3.19 MeV,but they are consistent with the cross section values available at 2.98±0.26 and 3.0±0.1 *** result at 2.15 MeV is slightly higher than the literature value available in EXFOR,evaluated value,and theoretically predicted result.
