Abstract:
The current standard treatment for intrahepatic cholangiocarcinoma is surgical resection. However, in case the patient does not agree with surgical resection or is not fit for surgery, there are a few alternative treatments. We present a case of an 83-year-old male patient with abdominal pain who was diagnosed with polypoid intrahepatic cholangiocarcinoma in the left intrahepatic duct (IHD) with peripheral IHD dilatation. He refused to undergo curative surgery. Alternatively, he underwent endoscopic mucosal resection (EMR) with direct peroral cholangioscopy (POC) using standard upper endoscopy with a transparent cap. At 1-year follow up, there was no evidence of locoregional recurrence or distant metastasis. We suggest that intraductal EMR could serve as an effective and safe alternative treatment for patients with polypoid intrahepatic cholangiocarcinoma using direct POC.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
