Background Contemporary EUS-guided FNA techniques involve the use of a needle, with an air column within the lumen, with or without suction. We describe a novel technique with an aim to improve the ...quality of the aspirate. Objective To compare a novel “wet suction” technique (WEST) with the conventional FNA technique (CFNAT) of EUS-guided FNA using a 22-gauge FNA needle. Design Prospective, single-blind, and randomized trial. Setting Two large tertiary-care hospitals. Patients All consecutive adult patients presenting for EUS with possible FNA of solid lesions were offered the chance to participate in the study. Methods All lesions were sampled with the same needle by using alternating techniques. Patients were randomized to the WEST versus the CFNAT for the first pass. If the first pass was made with the WEST, the second pass was made with the CFNAT, and subsequent passes were made in an alternating manner by using the same sequence. All FNAs were performed using 22-gauge needles. Main Outcome Measurements Specimen adequacy, cellularity, and blood contamination of EUS-guided FNA aspirates graded on a predefined scale. Results The WEST yielded significantly higher cellularity in a cell block compared with the CFNAT, with a mean cellularity score of 1.82 ± 0.76 versus 1.45 ± 0.768 ( P < .0003). The WEST cell block resulted in a significantly better specimen adequacy of 85.5% versus 75.2% ( P < .035). There was no difference in the amount of blood contamination between the 2 techniques. Limitations Lack of cross check and grading by a second cytopathologist. Conclusion The novel WEST resulted in significantly better cellularity and specimen adequacy in cell blocks of EUS-guided FNA aspirate of solid lesions than the CFNAT.
A multivariate logistic regression analysis adjusting for patient demographics, hospital characteristics, comorbidities and AP etiology demonstrated that CDI was associated with increased mortality ...adjusted odds ratio (aOR) 3.15, 95% CI 2.78-3.57, p < 0.001, LOS adjusted regression coefficient (aRC) 8.85, 95%CI 8.62-9.08, p < 0.001 and higher hospital charges (aRC $48,725, 95%CI $47,024-$50,425, p < 0.001). Indiscriminate use of antibiotics and poor compliance to the guidelines was reported in a recent audit 5. Besides encouraging...
Abstract Background & Aims Population based data on the burden and patterns of acute pancreatitis (AP) early readmissions (≤30-days) are limited. Methods 2013 Nationwide Readmission Database (NRD) ...was queried. AP etiology was determined using associated diagnoses codes. Proportion, reasons for readmission, and associated costs were evaluated. Multivariate logistic regression analysis was performed to identify independent predictors for 30-day readmission. Results After exclusions, we identified 178,541 patients with primary diagnosis of AP (mean age 53 ± 17 years, 51% male). 13.7% were readmitted ≤30 days 7.1% in acute biliary pancreatitis (ABP) patients with index cholecystectomy (CCY), 16.3% in ABP patients without CCY, and 14.3% in non-biliary AP patients (p < 0.0001). Reasons for readmission included AP, chronic pancreatitis, Pseudocyst/walled off necrosis, biliary tract disease, smoldering symptoms and others. On multivariate analysis male gender, comorbidity status (≥3), non-biliary etiology, organ failure, Pseudocyst/walled off necrosis complications, and patients discharged to extended care facilities were associated with increased risk of readmission. ABP patients with index CCY had a significantly lower risk of early unplanned readmission (odds ratio 0.45, p < 0.0001) but ABP patients with index ERCP did not (p = 0.96). Conclusions About 1 in 7 AP patients had a 30-day readmission after index hospitalization and about half of these were related to AP. Our data confirms the higher risk of readmission in alcohol and idiopathic AP and a lower risk in ABP. Risk of early unplanned readmission is significantly lower in ABP patients who underwent CCY and not ERCP during index hospitalization. Cholecystectomy should be performed in all ABP patients as per recommended guidelines.
