In Japan,liver biopsies were previously crucial in evaluating the severity of hepatitis caused by the hepatitis C virus(HCV)and diagnosing HCV-related hepatocellular carcinoma(HCC).However,due to the development of effective antiviral treatments and advanced imaging,the necessity for biopsies has significantly *** change has resulted in fewer chances for diagnosing liver disease,causing many general pathologists to feel less confident in making liver biopsy *** article provides a comprehensive overview of the challenges and potential solutions related to liver biopsies in ***,it highlights the importance of considering steatotic liver diseases as independent conditions that can coexist with other liver diseases due to their increasing ***,it emphasizes the need to avoid hasty assumptions of HCC in nodular lesions,because clinically diagnosable HCCs are not targets for ***,the importance of diagnosing hepatic immune-related adverse events caused by immune checkpoint inhibitors is increasing due to the anticipated widespread use of these *** conclusion,pathologists should be attuned to the changing landscape of liver diseases and approach liver biopsies with care and attention to detail.

Transnasal endoscopic retrograde chalangiopancreatography using an ultrathin endoscope: A prospective comparison with a routine oral procedure

引用

World Journal of Gastroenterology 2008年第10期14卷 1514-1520页

作者： Akihiro Mori Noritsugu Ohashi takako Maruyama Hideharu Tatebe Katsuhisa sakai Takashi Shibuya Hiroshi Inoue Shoudou Takegoshi Masataka Okuno Department of Gastroenterology Inuyama Chuo Hospital Inuyama 484-8511 Japan

AIM: To investigate if transnasal endoscopic retrograde cholangiopancreatography (n-ERCP) using an ultrathin forward-viewing scope may overcome the disadvantages of conventional oral ERCP (o-ERCP) related to the large- caliber side-viewing duodenoscope. METHODS: The study involved 50 patients in whom 25 cases each were assigned to the o-ERCP and n-ERCP groups. We compared the requirements of esophagogastroduodenoscopy (EGD) prior to ERCP, rates and times required for successful cannulation into the pancreatobiliary ducts, incidence of post-procedure hyperamylasemia, cardiovascular parameters during the procedure, the dose of a sedative drug, and successful rates of endoscopic naso-biliary drainage (ENBD). RESULTS: Screening gastrointestinal observations were easily performed by the forward-viewing scope and thus no prior EGD was required in the n-ERCP group. There was no significant difference in the rates or times for cannulation, or incidence of hyperamylasemia between the groups. However, the cannulation was relatively difficult in n-ERCP when the scope appeared U-shape under fluoroscopy. Increments of blood pressure and the amount of a sedative drug were significantly lower in the n-ERCP group. ENBD was successfully performed succeeding to the n-ERCP in which mouth-to-nose transfer of the drainage tube was not required. CONCLUSION: n-ERCP is likely a well-tolerable methodwith less cardiovascular stress and no need of prior EGD or mouth-to-nose transfer of the ENBD tube. However, a deliberate application is needed since its performance is difficult in some cases and is not feasible for some endoscopic treatments such as stenting.
