Computed tomography versus Acute Physiology and Chronic Health Evaluation II score in predicting severity of acute pancreatitis: a prospective, comparative study with statistical evaluation.

Objective: The aim of the study was to compare Acute Physiology and Chronic Health Evaluation II score and C-reactive protein as a clinical index and computed tomography-based severity index (CTSI) in predicting the course of acute pancreatitis.

Methods: One hundred forty-eight patients with acute pancreatitis were enrolled in the study during a 2-year period. All data concerning etiology, Atlanta classification, CT findings, Acute Physiology and Chronic Health Evaluation score, C-reactive protein levels, stay in the intensive care unit, length of hospital stay, treatment, complications, and deaths were analyzed with Mann-Whitney U, Wilcoxon, Pearson, and Spearman statistical tests.

Radiation doses to patients from enteroclysis.

The purpose of this study was to determine the patient doses during enteroclysis and compare them with the available bibliographical data. For 14 enteroclysis examinations, the dose-area product (DAP) meter readings, fluoroscopy time, number of radiographs and exposure data were recorded. From these data, the fluoroscopy and radiography contributions to DAP, the entrance surface dose (ESD) and the effective dose (E) for each examination were estimated.
