The main objectives of the working group are:\n\nTo create a working basis for analyzing the diagnostic features, treatment modalities and outcomes of interest of both the antibiotic-first approach and appendectomy for patients with uncomplicated AA.\n\nTo investigate the clinical, laboratory and radiologic modalities adopted for the diagnosis To determine the outcomes of patients treated with antibiotics or appendectomy in the short and long term periods.\n\nTo compare results according to the type of intervention. To stratify the risk of recurrence for patients treated with antibiotics according to clinical, laboratory and radiology findings.\n\nTo evaluate the sensibility and specificity of clinical and laboratory scores for the diagnosis of uncomplicated AA.\n\nTo identify a subgroup of patients with uncomplicated AA for whom antibiotic treatment can be highly effective.\n\nGeneral study design The study protocol is designed according to the "SPIRIT 2013 explanation and elaboration: guidance for protocols of clinical trials".\n\nThe study period is estimated to be of 12 month + 12 month of follow-up (with a second session of follow-up following 5-years), beginning on 01/04/2017.\n\nParticipants All adult patients (aged over 18 years old) with suspected AA will be admitted to the Surgical Department of the nine participating Italian hospitals, where they will be studied carefully by the on call surgeon.\n\nPatients will be then informed of the study protocol and invited to give written consent for participation and for sensible data collection for scientific purposes.\n\nSubsequently, only patients who will undergo diagnostic imaging (as specified later) and from whom a written informed consent will be obtained, can be enrolled in the study and registered by each Center using a uniform electronic registration form and database.\n\nGeneral characteristics, medical history, clinical findings, physical investigation, and blood tests will be reported in the medical record. Pain will be quantified by Visual Analogue Scale (VAS) scoring system before administrating any pain medications and after the treatments.\n\nIn order to enter the study, patients will have to undergo diagnostic imaging (US and/or CT scan or MRI scan) and only the diagnosis of uncomplicated AA confirmed by diagnostic imaging will permit patient enrollment in the study.\n\nSpecific aims of the ACTUAA Study The objective of this prospective non-randomized controlled, multicenter, multidisciplinary trial is to compare the antibiotic therapy and emergency appendectomy for the treatment of patients with uncomplicated AA(without abscess or free perforation), confirmed by US and/or CT or MRI scan. No changes in the daily practice regarding the diagnostic, clinical and treatment pathways will be required to the participating centers. However, only the patients with uncomplicated AA, confirmed by one of the above mentioned radiologic tools will be enrolled in the study. The decision on which of the tools are to be adopted will be up to the local lead surgeon.\n\nPrimary Outcome Measure:\n\nNumber of participants with complication-free treatment success, defined as success of the initial treatment with uncomplicated course.\n\nSecondary Outcome Measures:\n\nLength of hospital stay; Pain evaluation; Time to return to normal activity; Period of sick-leave; Complicated appendicitis with peritonitis identified at the time of surgical operation; Quality of life as assessed by the Short Form 12-scale (SF-12)'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'All adult patients (aged over 18 years old) with suspected Acute Appendicitis admitted to the Surgical Department of the nine participating Italian Hospitals', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Signed informed consent\n* Age over 18 years\n* Uncomplicated AA confirmed by US and/or CT or MRI scan.\n\nExclusion Criteria:\n\n* Pregnancy or lactating\n* Diffuse peritonitis at physical examination\n* Serious systemic illness\n* Positive anamnesis for Inflammatory Bowel Disease (IBD)'}, 'identificationModule': {'nctId': 'NCT03080103', 'acronym': 'ACTUAA', 'briefTitle': 'Appendectomy Versus Conservative Treatment for Uncomplicated Acute Appendicitis', 'organization': {'class': 'OTHER', 'fullName': 'Associazione Chirurghi Ospedalieri Italiani'}, 'officialTitle': 'A Prospective Non-randomized Controlled, Multicenter, Multidisciplinary Trial Comparing Appendectomy and Conservative Treatment for Patients With Uncomplicated Acute Appendicitis (the ACTUAA STUDY).', 'orgStudyIdInfo': {'id': 'No ID'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Patients submitted to appendectomy as first-line treatment', 'description': 'Open or Laparoscopic Appendectomy The assignment of each patient to either the "antibiotic-first management" arm or the "immediate surgery" arm, will be non-randomized and decided independently by the Staff Specialist Surgeon on Call, upon careful assessment of AIR score, laboratory findings and imaging.
