Active clinical trials for "Appendicitis"

Acute appendicitis is the first visceral surgical emergency in pediatrics with about 30,000 cases in children having been described in France. It concerns 0.3% of children under 15 with a maximum frequency between 8 and 13 years of age. Acute appendicitis has a significant morbidity rate of 8% and a mortality rate under 0.1%. 10 to 25% of the children admitted to emergency rooms for abdominal pain have appendicitis. In 20 to 30% of the cases, the initial symptoms are atypical, which explains the difficulty in diagnosing. The purpose of our study is to evaluate the quality of general practitioners in the diagnosis of acute appendicitis, its severity and the diagnostic criteria used. Furthermore, it is not as easy to evaluate pain or examine a complaint in children as it is in adults. Appendicectomy is the treatment of choice for all acute appendicitis. The importance of early diagnosis and treatment is, therefore, essential. Many predictive diagnostic scores have been studied over the years. The Pediatric Appendicitis Score (PAS) using typical symptoms of acute appendicitis and biological items was published in 2002. Nowadays, it is still considered as a reference and has been validated by other studies. Most of the patients suffering from abdominal pain first consult their general practitioner.

Aims of this study are : Estimate the incidence of A.A. in patients above age of 30 y in 4 age groups . Correlate between different clinical aspects and histopathological results. Determine rate of negative appendectomy in those patients.

prospective study to collect data of patients with appendicitis, not receiving operation

The Hasselt Appendicitis Immunology and Environmental Study (HAPPIEST) aims at characterizing factors that influence the development and severity of acute appendicitis. In a cohort of 300 patients and 300 controls, environmental factors as well as genetic make-up of the innate immune system, focusing mainly on pattern recognition, will be analyzed in order to gain insight in their relative importance in the pathology of appendicitis. Furthermore, populations of micro-organisms present in the gut of patients will be characterized, and the interaction between relevant micro-organisms and the innate immune system will be analyzed.

The purpose of this study is to compare the incidence rate of leukemia between CT-exposed and CT-unexposed group in patients who underwent appendectomy in South Korea.

The diagnosis of acute appendicitis remains a challenge in daily clinical practice. The high incidence of appendicitis drives the need to reduce morbidity and unnecessary costs due to negative appendectomies. The aim of the present observation study is to evaluate a diagnostic and therapeutic algorithm for suspected acute appendicitis. The investigators believe that this diagnostic algorithm helps to simultaneously avoid unnecessary operations, costs and radiation exposure.

Appendectomy is the most common emergent operative procedure performed worldwide. In this study investigators will investigate if there is a relationship between breast feeding and appendicitis in adults.

The Percutaneous drainage of symptomatic intra-abdominal collection (primary or secondary to surgery)is the treatment of choice in the absence of peritonitis signs. In critically ill patients, this procedure allows to avoid or postpone surgery. In these settings, the percutaneous drain can be either in Active Vacuum Pressure or in Free drainage. However, no prospective trials has assessed the efficiency of these two modalities of drainage in cases of infected intra-abdominal collections. The investigators aimed then to prospectively analyzed the efficiency (in term of infectious control) of drainage under active vacuum pressure vs. free drainage for the treatment of infected intra-abdominal collections.

The Investigators aim to assess; whether the changes in managing patients during COVID has reduced the negative appendicectomy rate? compare the difference in outcomes of conservatively and surgically managed Acute Appendicitis? Whether there uniformity in prescribing postoperative antibiotics with resultant outcomes? Whether the incidence of complicated appendicitis has increased?
