Filter by:Trial The aim of the study is to investigate which infectious diseases might mimic the symptoms of acute appendicitis to a degree to cause a diagnostic laparoscopy or laparoscopic appendectomy. The primary outcome is to compare the incidence of Yersinia spp. infection in patients, who undergo surgery due to suspected appendicitis, between those with and without appendicitis detected by polymerase chain reaction on rectal swabs. The secondary outcomes are comparison of the incidence of bacterial pathogens (Campylobacter spp., Salmonella spp., Shigella spp., Aeromonas spp.) and Enterobius vermicularis in the two groups. Rectal swabs, appendix swabs, and blood samples are collected prospectively and research biobanks will be established. Initially, the rectal samples and serology samples will be investigated, and possible biomarkers and results of the appendix swabs will be evaluated at a later time point. Ethics The trial will be conducted according to the Helsinki II Declaration after approval from both the local Health Research Ethics Committee and the Danish Data Protection Agency. An informed written consent will be collected from the participants prior to inclusion in the study. Data will be stored according to the approval from the Danish Data Protection Agency. This study is conducted in patients with suspected appendicitis. These patients are fully awake and conscious at time of inclusion. The patients included in this study will not experience any adverse effects due to their participation.
On September the 15th, 2015, Italian surgeons, radiologists and pathologists with a special interest and expertise in the diagnosis and management of Acute Appendicitis (AA), met up under the auspices of the Italian Society of Hospital Surgeons (ACOI) in Oristano (Italy) to constitute the ACTUAA collaborative working group. The main objectives of the working group are: To 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. To 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. To 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. To evaluate the sensibility and specificity of clinical and laboratory scores for the diagnosis of uncomplicated AA. To identify a subgroup of patients with uncomplicated AA for whom antibiotic treatment can be highly effective. General study design The study protocol is designed according to the "SPIRIT 2013 explanation and elaboration: guidance for protocols of clinical trials". The 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. Participants 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. Patients will be then informed of the study protocol and invited to give written consent for participation and for sensible data collection for scientific purposes. Subsequently, 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. General 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. In 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. Specific 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. Primary Outcome Measure: Number of participants with complication-free treatment success, defined as success of the initial treatment with uncomplicated course. Secondary Outcome Measures: Length 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)
Performing anesthetic induction for appendicectomy has two main risks : first aspiraion of gastric content causing pneumonia. Otherwise, anaphylactic risk to drugs used during anesthetic induction. Indeed, the guidelines recommend an anesthetic induction protocol qualified "full stomach" whatever the patient and the preoperative fasting period are. This protocol provides the use of fast-acting neuromuscular blocking agents (succinylcholine or rocuronium). However, these neuromuscular blocking agents are ten times more at allergic risk than others. Ultrasound assessment of gastric content before rapid sequence induction of anesthesia is a reproducible, non-invasive, inexpensive and quickly achievable bedside technique. Furthermore, the correlations between gastric volume and risk of a full stomach and also between the cross-section antral area (CSA) and the risk of a full stomach have been validated on several patient cohorts. We formulate the hypothesis that the achievement of a gastric ultrasound before anesthetic induction for appendectomy could allow to identify "full stomach" patients who actually justify rapid sequence induction of anesthesia with exposure to fast-acting neuromuscular blocking agents that implies. Primary endpoint is to determine te percentage of patients who have a gastric content before appendectomy. Secondary endpoint is to determine the incidenc of aspiration pneumonia and anaphylactic shock. Another secondary endpoint is to determine the percentage of patient with gastric content with the antral grading system (Perlas method) and to evaluate the concordance between this methode and the cross-section antral area.
Women having cesarean section will be divided into two groups - cesarean section alone or cesarean section with appendectomy. The purpose is to see if the appendectomy can be done without adding any complications to the maternal post-operative course. The hypothesis is that there is no increased incidence of wound infection, post-operative morbidity or longer hospital stay associated with elective appendectomy at the time of Cesarean Section.
