NCT07496723
Acute appendicitis is one of the most common surgical emergencies, but diagnostic uncertainty may still lead to unnecessary appendectomy in some patients. This prospective observational study aims to evaluate the diagnostic performance of computed tomography (CT) reporting and the Appendicitis Inflammatory Response (AIR) score in adult patients undergoing appendectomy for suspected acute appendicitis. The primary objective is to determine the negative appendectomy rate based on final histopathology. Secondary objectives are to assess the agreement between AIR score, CT findings, intraoperative severity grading, and pathology results, and to explore diagnostic performance across patient subgroups. No study-specific intervention beyond routine clinical care will be performed.
NCT07479849
Acute appendicitis is the most common abdominal surgical emergency in children and a frequent cause of pediatric emergency department visits. Diagnosis may be challenging due to variable clinical presentations and overlapping symptoms with other causes of abdominal pain. The increasing use of telemedicine further limits access to direct physical examination. This study aims to evaluate and validate a predictive clinical score designed for teleconsultation to estimate the probability of acute appendicitis in children. The score is based on symptom history and simple clinical signs assessed remotely with the assistance of a parenton a 10 item checklist. During an emergency visit for acute abdominal pain, voluntary children aged 3 to 16 years and their parents will be guided by a medical student through the checklist in conditions simulating a teleconsultation. The score will be recorded for research purposes only and will not influence clinical management. All participants will subsequently undergo standard medical evaluation and management by an emergency physician, who will independently assess the probability of acute appendicitis based on routine clinical practice. The diagnostic performance of the simulated teleconsultation will then be evaluated using advanced statistical and artificial intelligence-based methods and compared with standard in-person pediatric emergency consultation.
NCT06808087
This study aims to compare the effectiveness of TAP (Transversus Abdominal Plane) block, ESPB (Erector Spinal Plane Block), and tramadol in preoperative pain management for patients diagnosed with acute appendicitis and undergoing emergency surgery in the emergency department. The study will evaluate the potential of TAP block and ESPB administered to patients diagnosed with acute appendicitis in the emergency department to reduce pain intensity before surgical intervention. This study aims to contribute to practical applications to ensure optimal pain control for acute appendicitis patients under emergency department conditions.
NCT07370896
The project aims to determine the frequency of use of the Alvarado score among emergency department physicians at facilities in Villavicencio, Colombia. The information will be collected using a self-directed survey with items assessing awareness, compliance, and systematic recording of the Alvarado score among patients with abdominal pain and suspected acute appendicitis, as predictors of illness and severity.
NCT01839435
The aim of our monocentric prospective in intention-to-treat study is to evaluate the feasibility of outpatient appendectomy for non complicated acute appendicitis.
NCT07008092
Diagnosing acute appendicitis in children remains a clinical challenge, with delayed or incorrect diagnosis potentially leading to serious complications or unnecessary surgery. Prostaglandin E urinary metabolites (PGE-M) have been found elevated in various inflammatory conditions, but their diagnostic value in pediatric appendicitis is not well established. This study aims to assess the potential of PGE-M as a biomarker for acute appendicitis in children. The study will be conducted over 12 months and will include 100 children aged 5 to 17 years presenting with acute abdominal pain. In addition to routine laboratory tests, urinary PGE-M levels will be analyzed. The study involves minimal risk to participants
NCT06897709
Objective: This study aims to compare the standard laparoscopic appendectomy with the "Stump-First Approach" technique in patients diagnosed with acute appendicitis in terms of intraoperative and postoperative complications that may occur (injury, intra-abdominal abscess, postoperative fever, and infection parameters).
NCT05470517
Appendicitis (inflammation of the wall of the appendix, causing pain and tenderness in the abdomen) has a range of severity that goes from simple to complicated. Complicated appendicitis may present with infected fluid inside of the abdomen or a perforation or hole in the intestines. This research is being done to determine if placing an antibiotic solution in the abdomen at the time the appendix is removed is a safe procedure in patients between the ages of 3 and 18 years old with findings of complicated appendicitis. Johns Hopkins All Children's Hospital (JHACH)'s current standard of care for patients with complicated appendicitis includes suctioning the infected fluid out of the abdomen at the time the appendix is removed. As part of this study, the investigators would like to see if patients with complicated appendicitis will benefit from routine care plus leaving an antibiotic solution inside the abdomen, after fully suctioning the infected fluid out of the abdomen.

NCT05033249
Acute appendicitis is the most common cause of abdominal pain requiring surgery in the emergency department. The whole life acute appendicitis rate is 7%. Only half of the patients with acute appendicitis are presented with typical periumbilical pain following by nausea, vomiting, and the migration of pain to the right lower quadrant. The diagnosis of acute appendicitis is based on the patient's medical history, physical examination, and laboratory findings. The Alvarado scoring system (ASS), recommends discharge, observation, and surgical intervention to patients. However, such scoring systems should not be used as the only method in diagnosis. Increased imaging use in patients with suspected acute appendicitis improved the rate of correct diagnosis. American College of Radiology Appropriateness Criteria (ACR) recommends computerized tomography (CT) as the primary imaging method to confirm the diagnosis of acute appendicitis in adults. However, CT imaging has some disadvantages, such as radiation exposure, undesirable effects associated with the use of contrast agents, and increased workload in the emergency room. The count of immature granulocytes (IGC), which is an indicator of increased activation of the bone marrow, and the percentage of IG (IGP), which is the ratio of IGs to the total white blood cell count, are also has been used differentiation of complicated acute appendicitis from uncomplicated acute appendicitis, and other inflammatory pathologies. Nowadays automatic blood analyzers can easily measure the amount and percentage of IGs simultaneously in a complete blood count test with advances in technology. It is aimed to investigate the utility of IGC and IGP on the prediction of suspected acute appendicitis according to the ASS and its effect on the need for CT scanning.
NCT06175169
the investigators's study group has developed a fully automated 3D convolutional neural network (CNN)-based diagnostic framework using information of appendix (IA) model to identify non-appendicitis and simple and complicated appendicitis on CT scan images based on the two-stage binary classification algorithm, as a clinician does for deciding treatment. The dataset was built from a large population of patients visiting emergency departments who underwent intravenous contrast-enhanced abdominopelvic CT examinations to evaluate abdominal pain in the right or lower quadrant area as the chief complaint. Recently, the IA model was externally validated using a dataset of multicenter institutions through data exfiltration. In this study, the investigators hypothesized that the IA model would show a comparable negative appendicitis rate of \<10% non-inferior margins compared to non-radiologists with a shorter interpretation time in a prospectively randomized dataset.
NCT05238506
Intravenous lidocaine - a potent local anesthetic with analgesic and anti- inflammatory properties has been shown to be an effective adjunct that reduces intra and postoperative opioid consumption and facilitates pain management in adults. In children population promising but limited evidence is available. The study has been planned to evaluate the efficacy of continuous intravenous infusion of lidocaine in alleviation of hemodynamic reaction to tracheal intubation, as well as metabolic and hormonal response to laparoscopic procedure in children.
NCT05651360
The goal of this non-inferiority observational study is to assess the diagnostic performance of low-dose CT with deep learning image reconstruction (DLIR) in adult participants with acute abdominal conditions. The main research question is: • Can low-dose CT with DLIR achieve the same diagnostic performance as standard CT for the diagnosis of acute abdominal conditions. Participants will be examined with an additional low-dose CT directly after the standard CT. Participant will be their own controls.
NCT04440150
Appendectomy is the most effective treatment option for acute appendisitis, which is the most commen emergent surgical pathology. However with in time period, surgical treatment borders are narrowed. Especially in uncomplicated acute appendicitis cases, nonoperative management (NOM) with antibiotherapies becomes primary treatment option. The COVID-19 pandemic, which is caused by 2019 novel coronavirus (2019-nCoV) and we encountered in the current process, has led to the re-questioning of surgical elective and emergency cases. Serious complications and increased mortality rates of the 2019-nCoV creates a novel problems of patient selection for emergent surgery and health care workers faced with potential health problems. As the same as the other surgical procedures, in the uncomplicated acute appendisitis cases NOM become more mandantory. NOM of uncomplicated acute appendisitis doen't increase perforation risk and general practice for decreasing surgical complications in the COVID-19 pandemic period. Additionally complicated acute appendicitis accounts for 20 to 30% of the patients undergoing appendectomy and lead to increased risk of postoperative complications, delayed recovery and longer hospital stay. Therefore, early diagnosis of complicated acute appendicitis is important; however, the most appropriate and inexpensive diagnostic method to make this diagnosis has not been established yet. Although the use of imaging methods is widespread, these methods are not accessible in many rural hospitals due to the high costs and unavailability of specialists. Thus, the need for an inexpensive and effective diagnostic technique allowing to make a differential diagnosis has not been met yet. For this purpose, several inexpensive and easily accessible blood parameter tests have been proposed; including the white blood cell count, immature granulocyte (IG) percentage, C-reactive protein levels or the neutrophil-to-lymphocyte ratio. An increase in the IG count shows that the bone marrow is active. This parameter has been used as a prognostic factor in many infectious and non infectious diseases including sepsis, acute pancreatitis, and acute myocardial infarction. The Immature granulocyte (IG) fraction includes promyelocytes, myelocytes, and metamyelocytes but not band neutrophils or myeloblasts. The IG count and percentage has become an easy-to-use method, especially with the introduction of technological advances, as it can be easily determined using the results of a routine complete blood count. It is aimed to efficacy of IG count and percentage which are calculated automatically in CBC samples, to differatiate the complicated and uncomplicated acute appendicitis cases with a cheap, easily applicable and cost effective test, especially in rural areas without enough diagnostic tests in COVID-19 pandemy.
NCT06051825
Diagnosing acute appendicitis in children is still a challenge even for experienced clinicians. Failure to recognize this acute condition can result in perforation, with consequent peritonitis, or misdiagnosis can result in negative appendectomies. C-reactive protein in blood can be elavated in children with acute appendicitis. The aim of this research is to compare the diagnostic value of C-reactive protein from the blood and saliva of children with acute appendicitis and to prove wheter the analysis of biomarker from saliva as a minimally invasive procedure can be sufficient for diagnosis.
NCT03687502
This study seeks to determine the efficacy of Contrast Enhanced Ultrasound (CEUS) in improving the diagnosis of acute appendicitis in children, when compared to the standard grey-scale ultrasound.
NCT03688295
Around 30% of appendectomies are performed for complicated acute appendicitis (CAA, i.e. cases with perforated appendicitis, extraluminal fecaliths, abscesses, or local or generalized peritonitis). The treatment of these complicated forms involves the following steps: initiation of antibiotic treatment at the time of the diagnosis, appendectomy and post-operative antibiotic therapy that continues for 3 days for localized forms of CAA and for 5 days for generalized peritonitis (according to the guidelines issued by the French Society for Anaesthesia and Critical Care Medicine (SFAR)). The results of a Cochrane meta-analysis published in 2005 suggested that the post-operative infection rate was lower in patients having receiving antibiotic therapy after surgery for AA. When only cases of CAA were considered, the difference was no longer significant. However, it should be noted that the studies included in the meta-analysis are now rather old (published before 1995, with open procedures) and no longer provide valid data for answering this question because most appendectomies (80%) are now performed using laparoscopy. Furthermore, a recent cohort study compared a short (3-day) course of antibiotics with a long course (at least 5 days) in patients with CAA having undergone laparoscopic or open appendectomy. There was no significant intergroup difference in the post-operative complication rate. One can thus legitimately question whether post-operative antibiotic therapy is required after laparoscopic appendectomy for CAA. The purpose of the present study is to evaluate the impact of the absence of post-operative antibiotic therapy on the organ space surgical site infection (SSI) rate in patients presenting with CAA (other than cases of generalized peritonitis) by comparing a group of patients having undergone a conventional strategy of post-operative antibiotic therapy for three days after appendectomy for CAA (the control group) with a group of patients having received a post-operative placebo for three days after appendectomy for CAA (the experimental group). The primary endpoint will be evaluated at one month after randomization.
NCT05843630
Non-operative management (NOM) with antibiotics may be a safe alternative to surgery for uncomplicated appendicitis, but preoperative differentiation between uncomplicated and complicated appendicitis is challenging. The study aimed to develop a clinical-radiomics nomogram to distinguish uncomplicated from complicated appendicitis.
