Article Synopsis
- This text discusses various surgical techniques for minimally invasive left hepatic resection, highlighting their pros and cons.
- It examines key surgical approaches like the left hepatic vein approach, transection, and Glissonean approach, offering guidance for surgeons on choosing the best method.
- The article includes videos from several centers to visually demonstrate successful surgeries and aims to help surgeons tailor their strategies to patient needs and lesion characteristics.
Transduodenal Ampullectomy (TA) is a procedure for resecting low-malignancy ampullary tumors, with postoperative fistula as a notable complication. This study aims to clarify the indications for TA, outline the surgical robotic technique, and emphasize the importance of comprehensive complication management alongside the surgical approach. This multimedia article provides a detailed exposition of the robotic TA surgical technique, including the most important steps involved in exposing and reimplanting biliary and pancreatic ducts.

Nowadays, the robotic approach is gaining increasing interest among the surgical community, and more and more series describing robotic liver resection have been reported. However, few cases of minimally invasive Bismuth type IIIA cholangiocarcinoma have been reported.

The relationship between inflammation and cancer is well established in several tumor types, including bladder cancer. We performed an association study between 886 inflammatory-gene variants and bladder cancer risk in 1,047 cases and 988 controls from the Spanish Bladder Cancer (SBC)/EPICURO Study. A preliminary exploration with the widely used univariate logistic regression approach did not identify any significant SNP after correcting for multiple testing.
View Article and Find Full Text PDFAssociation studies are the choice approach in the discovery of the genomic basis of complex traits. To carry out such analysis, researchers frequently need to (1) select optimally informative sets of Single Nucleotide Polymorphisms (SNPs) in candidate regions and (2) annotate the results of associations found by means of genome-wide SNP arrays. These are complex tasks, since many criteria have to be considered, including the SNPs' functional properties, technological information and haplotype frequencies in given populations.

It is conceivable that specific patterns of genetic susceptibility are associated with particular subphenotypes.
Objective: To examine evidence for the contribution of germline genetic variation to bladder cancer heterogeneity.
