Abstract BACKGROUND: Because of the potential risk of hemorrhage or ischemia, the presence of vascular anomalies adds to the surgical challenge in pancreatoduodenectomy (PD). OBJECTIVE: To analyze the literature concerning the influence of aberrant peripancreatic arterial anatomy on outcomes of PD. MATERIALS AND METHODS: A systematic search using Medline and Embase for the years 1950-2008. RESULTS: The most common aberration in hepatic arterial anatomy is the replaced right hepatic artery. Other vascular abnormalities such as replaced common hepatic artery with a hepatomesenteric trunk and celiomesenteric trunk and arcuate ligament syndrome leading to celiac artery stenosis are also associated with post-PD complications. Damage to the biliary branches of the hepatic arteries increases the risk of postoperative biliary anastomotic leak. CONCLUSION: The most common abnormalities of the hepatic vasculature include a replaced RHA, replaced LHA, and accessory RHA or LHA. Celiac artery stenosis secondary to median arcuate ligament compression may also be encountered. Every attempt should be made to preserve the aberrant vessel unless their resection is oncologically indicated. Routine preoperative computerized tomography angiography helps to identify the hepatic vascular anatomy and thereby prepares the surgeon to better deal with the vascular anomalies intraoperatively. Increased awareness of the vascular anatomy would decrease the chances of intraoperative vascular injury and consequent postoperative complications such as biliary anastomotic leaks as well as the chances of postoperative hemorrhage.

    Classically, the 3’untranslated region (3’UTR) is that region in eukaryotic protein-coding genes from the translation termination codon to the polyA signal. It is transcribed as an integral part of the mRNA encoded by the gene. However, there exists another kind of RNA, which consists of the 3’UTR alone, without all other elements in mRNA such as 5’UTR and coding region. The importance of independent 3’UTR RNA (referred as I3’UTR) was prompted by results of artificially introducing such RNA species into malignant mammalian cells. Since 1991, we found that the middle part of the 3’UTR of the human nuclear factor for interleukin-6 (NF-IL6) or C/EBP gene exerted tumor suppression effect in vivo. Our subsequent studies showed that transfection of C/EBP 3’UTR led to down-regulation of several genes favorable for malignancy and to up-regulation of some genes favorable for phenotypic reversion. Also, it was shown that the sequences near the termini of the C/EBP 3’UTR were important for its tumor suppression activity. Then, the C/EBP 3’UTR was found to directly inhibit the phosphorylation activity of protein kinase CPKC in SMMC-7721, a hepatocarcinoma cell line. Recently, an AU-rich region in the C/EBP 3’UTR was found also to be responsible for its tumor suppression. Recently we have also found evidence that the independent C/EBP 3’UTR RNA is actually exists in human tissues, such as fetal liver and heart, pregnant uterus, senescent fibroblasts etc. Through 1990’s to 2000’s, world scientists found several 3’UTR RNAs that functioned as artificial independent RNAs in cancer cells and resulted in tumor suppression. Interestingly, majority of genes for these RNAs have promoter-like structures in their 3’UTR regions, although the existence of their transcribed products as independent 3’UTR RNAs is still to be confirmed. Our studies indicate that the independent 3’UTR RNA is a novel non-coding RNA species whose function should be the regulation not of the expression of their original mRNA, but of some essential life activities of the cell as a whole.
