Although laparoscopic cholecystectomy (LC) is the gold standard, some patients still require an open cholecystectomy (OC). This study evaluates the mean number of OCs performed by each graduating general surgery resident during each of 3 decades. ⋯ There has been a considerable decline in the number of OCs, IOCs, and CBDEs available to our trainees during the past 30 years. New training paradigms should include renewed focus on performing an IOC and/or CBDE as clinically indicated during LC; high-quality simulation programs for OC, IOC, and CBDE; and the availability of an advanced video library depicting complicated open biliary procedures.

Patient triage in anatomically resectable, early stage pancreatic ductal adenocarcinoma (PDAC) with elevated carbohydrate antigen 19-9 (CA 19-9) remains unclear. We hypothesized that any CA 19-9 elevation indicates biologically borderline resectability. ⋯ The minority of PDAC patients have CA 19-9 measured and reported in NCDB. The CA 19-9 nonsecretors and normal-level patients achieve equivalent survival. Elevation of CA 19-9 is associated with decreased stage-specific survival, with the greatest difference in early stages. Neoadjuvant systemic therapy followed by curative intent surgery best mitigates the increased mortality hazard. Patients with PDAC who have elevated CA 19-9 levels at diagnosis are biologically borderline resectable regardless of anatomic resectability, and neoadjuvant systemic therapy is suggested.

MicroRNAs (miRNAs) are small segments of noncoding RNA that regulate gene expression and protein function, and therefore are key regulators of cellular processes including those of the inflammatory cascade after hemorrhagic shock (HS). We have previously shown that direct peritoneal resuscitation (DPR), as an adjunct to traditional IV fluid resuscitation, improves visceral blood flow and reduces pro-inflammatory cytokines released during HS. The effects of DPR on hepatic miRNA (miR) expression patterns after resuscitated HS are not known. ⋯ Adding DPR downregulated most hepatic miRNAs compared with CR alone. Some miRNAs were affected more significantly, suggesting that although this clinical intervention causes a near-global downregulation of hepatic miRNA, it still targets specific inflammatory pathways. Use of DPR for resuscitation of patients in HS may reduce hepatic inflammation to improve patient outcomes after hemorrhage.
