This study demonstrates that urgent ERCP would be recommended in the management of patients with CBD stone-related mild to moderate acute cholangitis because of the advantage of short hospital stay and intervention to discharge time.

Background: Monocyte-to-lymphocyte ratio (MLR), neutrophil-to-lymphocyte ratio (NLR), and platelet-tolymphocyte ratio (PLR) have been reported to be prognostic markers in various cancers. However, the prognostic value of these inflammatory biomarkers, particularly MLR, in gallbladder cancer remains to be determined. Methods: From 2005 to 2016, 178 patients with histologically confirmed gallbladder adenocarcinoma who underwent palliative chemotherapy were queried in this study. The association between survival and various clinical and laboratory variables, including MLR, NLR, and PLR, was investigated. The optimal cutoff values for MLR, NLR, and PLR were determined using the maxstat package of R. Results: Patients with high MLR (>0.24) were expected to have shorter progression-free survival [PFS; hazard ratio (HR), 2.100; 95% confidence interval (CI), 1.397-3.157; P < 0.001] and overall survival (OS; HR, 2.533; 95% CI, 1.664-3.856; P < 0.001) compared with patients with low MLR (0.24). In multivariate Cox model, CA 19-9, stage, and MLR were independent factors for PFS. MLR was also an independent predictor of OS along with PLR, age, and CA 19-9, whereas NLR was not significantly associated with OS. Time-dependent receiver operating characteristic (ROC) analysis showed that the area under the curve of MLR for predicting OS was greater than that of NLR and PLR at most time points. Conclusions: MLR independently predicts survival in gallbladder cancer patients undergoing chemotherapy. Future prospective studies are needed to validate its value as a prognostic biomarker. Impact: MLR is an inexpensive and easily available biomarker for predicting prognosis in patients with gallbladder cancer undergoing chemotherapy.

The addition of dexmedetomidine to the midazolam - meperidine regimen provided better sedative efficacy and a superior safety profile during ERCP compared with a midazolam - meperidine regimen.This trial was registered at ClinicalTrials.gov Identifier (NCT01404689).

The blood neutrophil-to-lymphocyte ratio (NLR) is reported to be a prognostic marker in several cancers. However, the prognostic role of NLR in patients with advanced cholangiocarcinoma on chemotherapy is unknown. A total of 221 patients with pathologically confirmed locally advanced or metastatic cholangiocarcinoma receiving first-line palliative chemotherapy were enrolled. Associations between baseline clinical and laboratory variables including NLR and survival were investigated. Patients were classified into two groups according to the NLR level (≤ 5 vs. >5). Median overall survival (OS) and time to progression (TTP) in patients with NLR ≤ 5 were 10.9 and 6.7 months, respectively, and 6.8 and 4.1 months in patients with NLR > 5 (P < 0.001, P = 0.002, respectively). In multivariate analysis, number of cycles of chemotherapy was a significant predictor of longer OS (HR 0.86, P < 0.001), whereas adverse prognostic factors for OS were CA 19-9 > 300 (HR 1.43, P = 0.025), CEA > 5 (HR 1.44, P = 0.029), higher stage (HR 1.69, P = 0.004), and NLR > 5 (HR 1.87, P < 0.001). NLR > 5 was also associated with reduced TTP (HR 1.66, P = 0.007). Among 50 patients with initial NLR > 5, 33 patients had NLR ≤ 5 after two cycles of chemotherapy and they had significantly better survival than the others (HR 0.48, P = 0.015). NLR independently predicts survival in patients with advanced cholangiocarcinoma undergoing chemotherapy. Considering cost-effectiveness and easy availability, NLR may be a useful biomarker for prognosis prediction.
