Abstract Background Although early laparoscopic cholecystectomy is widely performed for acute cholecystitis, the optimal timing of a in clinically ill patients remains controversial. This study aims to determine best practice presenting with cholecystitis focused on disease severity and comorbidities. Methods An international multicentric retrospective observational was conducted over 2‐year period. Patients were divided into four groups: Group A: primary cholecystectomy; B: after...

Serious complications continue to occur in laparoscopic cholecystectomy (LC). The commonly used indicators of surgical difficulty such as the duration surgery are insufficient because they surgeon and institution dependent. We aimed identify appropriate during LC.A total 26 Japanese expert LC surgeons discussed using nominal group technique (NGT) generate a list intraoperative findings that contribute difficulty. Thereafter, survey was circulated 61 experts Japan, Korea, Taiwan....

Vascular endothelial growth factor (VEGF) can be produced by monocytes and cells. It plays important role in angiogenesis vascular permeability. The phenomenon of extensive plasma leakage into various serous cavities the body is a cardinal symptom dengue hemorrhagic fever (DHF). This study was performed to investigate VEGF patients with DHF. Plasma samples collected from 53 (DF) (including 14 DHF), 5 additional subjects non-dengue febrile illness as controls were tested for levels using...

Tokyo Guideline 2013 (TG13) proposed three drainage techniques for the treatment of acute cholecystitis. We evaluated clinical efficacy and adverse events between percutaneous transhepatic intervention (PTGBI) including gallbladder (PTGBD) aspiration (PTGBA) endoscopic transpapillary (EGBD).A cohort study was performed using propensity score matching to reduce selection bias. This involved analysis collected data 1,764 patients who underwent PTGBI EGBD.Propensity extracted 330 pairs...

In this study, we try to compare the benefit of laparoscopic versus open operative procedures. Patients and Methods . One hundred sixteen patients underwent liver resection (LR) another 208 went for (OR) hepatocellular carcinoma (HCC). Patients' selection or approach was not randomized.

During mitosis, 2 centrosomes ensure accurate assembly of bipolar spindles and fidelity the chromosomal segregation. The presence more than copies during mitosis can result in formation multipolar spindles, unbalanced chromosome segregation, aneuploidy. Recent studies have provided evidence that centrosome hyperamplification plays a pivotal role carcinogenesis. Using immunofluorescence analysis with gamma-tubulin pericentrin antibodies, paraffin-embedded sections from 40 malignant biliary...
