Active clinical trials for "Appendicitis"

Although the presence of SIRS has been described in patients with appendicitis, its progressive response related and together with progression of symptomatology from the onset of symptoms to diagnostic has not been characterized. Continuation of the systemic inflammation in patients with injury and infectious processes may result in multiple organ dysfunction and ultimately failure. As with any acute inflammatory condition, the patients' systemic inflammatory response to appendicitis will progress and become more intense with the passing of time. The purpose of this study is to characterize the systemic inflammatory response to appendicitis from the beginning of symptoms to diagnostic in patients with appendicitis submitted to emergency surgery.

Rate of appendix localization on ultrasound is not high. We suggest a way to improve it's localization by oral administration of iodinated contrast material.

It has recently been published that hyperbilirubinemia is a reliable marker for the preoperative diagnosis of perforated acute appendicitis. The investigators believe, based on their own previous publications, that C-reactive protein (CRP) with or without a white blood cell count and some other clinical parameters, are more specific markers for the preoperative diagnosis of perforated acute appendicitis. The purpose of this study is to prospectively compare the specificity and sensitivity of hyperbilirubinemia CRP, white blood cell count and other clinical parameters for the preoperative diagnosis of acute appendicitis.

The values of laboratory examinations which are useful for the diagnoses of acute appendicitis are white blood cell count (WBC), C-reactive protein (CRP) and erythrocyte blood sedimentation rate (ESR). Another laboratory value which has recently received considerable attention for the early diagnosis of bacterial infection and sepsis is pro-calcitonin (PCT). In recent studies it has been clearly shown that PCT is one of the most important biochemical indicators which closely correlates with the severity of inflammatory host response to microbial infections. Aim of this open, prospective study is therefore to investigate if PCT has an accurate diagnostic value for the diagnosis of acute appendicitis.

The purpose of this study is to determine whether computed tomography is reliable investigation in the diagnosis of acute appendicitis.

Computer-aided diagnostic software has been used to assist physicians in various ways. Text-based prediction algorithms have been trained on past medical records through data mining and feature analysis. Currently, all text-based machine learning prediction problem models have been built on extracted data with no research completed on free text based prediction algorithms. This study aims to determine the accuracy of a free text prediction algorithm in predicting the probability of appendicitis in patients presenting to the Emergency Department with abdominal pain and gastrointestinal symptoms.

Acute appendicitis still represents a surgical challenge, despite profound changes in practice in recent decades. The objective of this study was comprehensively document current surgical practices aimed at improving the management and follow-up of pediatrics and adults patients presenting with appendicitis in France.

In this retrospective observational case study, the investigators review the clinical experience with pressure-pain algometry in children with suspected appendicitis. The investigators hypothesized that algometry can discriminate children with appendicitis from children without appendicitis and aimed to determine the diagnostic accuracy of algometry, compared to ultrasound imaging and clinical assessment.

Aim of the study: to identify the signs of acute appendicitis delta signs - clinical, laboratory or ultrasound signs, whose change (delta) would allow to identify or deny the diagnosis of acute appendicitis without a computed tomography examination and thus to lower computed tomography rates.

A retrospective observational study investigating whether retrocecal appendicitis associated with worse operative and postoperative outcomes than non-retrocecal appendicitis.
