The Prevalence of Appendiceal Tumours in Periappendicular Abscess
Appendix AbscessAppendicitis5 moreComplicated and uncomplicated appendicitis follow different epidemiological trends also suggesting different pathophysiology behind these two different forms of appendicitis. In 3-10% of patients complicated acute appendicitis is enclosed by formation of a circumscribed periappendicular abscess. The clinically established practice of antibiotic therapy and drainage, if necessary, has been shown safe and effective, allowing the acute inflammatory process to subside in more than 90% of cases without surgery. The need of subsequent interval appendectomy has been questioned with appendicitis recurrence risk varying between 5-26%. During trial enrollment in our randomized Peri-APPAC trial based on the interim analysis results with 17% appendiceal tumor rate in the study population, the trial was prematurely terminated based on ethical concerns. All the follow-up group patients were re-evaluated and surgery was offered and recommended to all follow-up group patients. After this assessment and additional appendectomies, two more tumors were diagnosed resulting in neoplasm rate of 20% in the whole study group all diagnosed in patients over 40 years and the neoplasm rate in patients over 40 years was 29%. Based on high appendiceal tumor rate in patients over 40 years, the appendiceal neoplasm rate needs to be further evaluated in prospective patient cohorts undergoing interval appendectomy as interval appendectomy is generally well tolerated and obliterates the risk of missing a possible tumor. In a recent systematic review of retrospective cohort studies with 13.244 acute appendicitis patients the overall appendiceal tumor rate was 1% after appendectomy, but in patients presenting with appendiceal inflammatory mass the neoplasm rate varied from 10% to 29%. This nationwide prospective multicenter cohort study is designed to assess the prevalence of appendiceal tumors associated with a periappendicular abscess. All consecutive patients presenting with a periappendicular abscess are recommended to undergo interval appendectomy after initial conservative treatment with antibiotic therapy and drainage, if necessary. All patients older than 35 years will undergo laparoscopic interval appendectomy at 2 to 3 months and this is also recommended for the patients between 18 and 35 years of age. Asymptomatic patients under 35 years not willing to undergo interval appendectomy, will undergo a follow-up MRI at 1 year after the initial non-operative treatment.
Re-assessment of Appendicitis Evaluation During Laparoscopic Appendectomy, Peritoneal Irrigation...
AppendicitisAppendectomyType: prospective observational multicenter trial. Population of interest: adult patients undergoing laparoscopic appendectomy for acute appendicitis. Hypothesis : laparoscopic lavage during laparoscopic appendectomy is a practice that should be used in selected patients according to the intraperitoneal grade of contamination and grade of appendicitis. Nonregulated use of laparoscopic lavage cannot be considered superior to suction only considering recent evidence. Few RCT available addressing this issue are available, but any with a high methodological quality. Aim: The aim of this study is to investigate the impact of laparoscopic lavage during laparoscopic appendectomy on the postoperative incidence of intrabdominal abscesses, stratifying patients in different clusters according to a defined classification considering the intraperitoneal contamination and grade of appendicitis.
Identification of the Optimal Treatment Strategy for Complex Appendicitis in the Pediatric Population...
AppendicitisAppendix Mass1 moreAim of this study is to evaluate the effect of different treatment strategies on overall complications, health related-Quality of Life (hr-QOL) and costs among two subtypes of complex appendicitis in children (<18 years old). Main research questions: What is the difference in overall complications at three months between: Subgroup 1 (complex appendicitis without abscess/mass formation): Laparoscopic (LA) and open appendectomy (OA) Subgroup 2: (complex appendicitis with abscess/mass formation): Non-operative treatment (NOT) and direct appendectomy
Non-operative vs. Operative Management of Acute Appendicitis in Vulnerable Patient Populations
Acute AppendicitisThe overall project goal is to conduct a pilot randomized clinical trial of operative (laparoscopic appendectomy) vs nonoperative (antibiotic) management of uncomplicated acute appendicitis for vulnerable populations. Specifically, the elderly, non-English speakers, and those with economic vulnerability (low socioeconomic status and/or manual labor jobs without a non-weight lifting aspect), are three vulnerable population subsets identified. This pilot trial will provide critical preliminary data for planning and conducting a larger multi-site randomized trial.
Point of Care 3D Ultrasound for Various Applications: A Pilot Study
AppendicitisEvidence of Cholecystectomy22 moreSummary Purpose and Objective: The purpose of this study is to test the feasibility of rapid acquisition of point of care 3D ultrasound in obtaining abdominal and/or pelvic images. The study will use a newly developed acquisition method and post-processing technique to create three dimensional image models of the abdomen and/or pelvis. Study activities and population group. The study population will be a convenience sample of patients of any age presenting to the Emergency Department with complaints necessitating a clinical abdominal and/or pelvic imaging. The study intervention includes acquisition of research ultrasound images, which will not be used for clinical care, and comparison of these images with clinically obtained images. Other clinical data such as surgical and pathology reports will also be reviewed. 3.Data analysis and risk/safety issues. This is a pilot study intended to determine feasibility and to refine image reconstruction algorithms. Research images will be compared to clinical images. Comparison of research images with final diagnosis will also occur. The research intervention, an ultrasound exam, has no known safety risks. The only risk to subjects is loss of confidentiality. This study is observational, not interventional, because the experimental ultrasound will be performed in all subjects and will not be used in the clinical care of patients (consequently, will not have the opportunity to affect clinical outcomes). Experimental images will be reviewed after completion of clinical care and will not be provided to the clinicians caring for the subjects. The investigators are not measuring the effect of the ultrasound examination on the subjects' outcomes.
Diagnostic Importance of the Circulating Human Leucine-rich α-2-glycoprotein in Acute Appendicitis...
Appendicitis AcuteAcute appendicitis is a common and potentially serious medical condition which can be difficult to diagnose, especially in pediatric patients. To help recognize patients with acute appendicitis, number of laboratory and radiological test are used. Previous research has shown that Circulating Human Leucine-rich α-2-glycoprotein (LGR1) in the blood can be elevated in pediatric patients with acute appendicitis. The aim of this research is to analyse whether LGR1 levels in saliva can be used as a less invasive diagnostic method in pediatric patients with suspected acute appendicitis.
Benefit of Hypnosis on Smartphone for Acute Post-operative Pain (HYPNO-APP)
Appendicitis With PeritonitisAppendicitis is a common pathology and the one of the most common surgical procedures performed in France. Young subjects are the most frequent patients with appendicitis. Appendicular peritonitis increases post-operative pain, morbidity, and the average length of hospital stay compared to uncomplicated appendicitis. Pain alters perioeprative rehabilitation of patients. Surgery, performed urgently, generates more anxiety and pain than scheduled surgery. But, intensity of chronic postoperative pain is in correlation to intensity of acute postoperative pain. In addition, admission of emergency cases is more axiety-inducing, due to wait times, packed emergency room, worklaod of medical staff. Sex and age also modify perception of postoperative pain. Adults under 50 feel more pain than older patients for similar procedures. Medication for pain is required in perioperative period et is administered according protocol of each medical center ; these protocols include analgesics, opioids or not, benzodiazepine... However, opioids analgesic (example: morphine) can induce side effect, such as confusional syndrome, cardio-pulmonary manifestations, ileus, nausea and vomiting... Non-pharmacological approaches have been also proposed to reduce anxiety and pain. Hypnosis is frequently used but not always adapted to the emergency: need for qualified and available staff, environment not conducive to hypnotic induction... Hypnosis is a modified state of consciousness ; it is neither a state of vigilance nor a state of sleep. Several types of hypnosis can be distinguished according to the medical application, such as hypnoanalgesia or hypnosedation. Using hypnosedation during surgical or invasive procedure can reduce the use of painkillers and sedatives. Interest of hypnosis has been observed for extraction of wisdow teeth, delivery... Young patients are very comfortable with the use of their smartphone which is often the first object recovered when they return from the operating room. Many hypnosis videos are available free of charge on Internet, and some of which are produced by specialized practitioners and university teachers. A recent study has shown that among young people, addiction to smartphone is a predisposition to hypnosis. However, the use of hypnosis videos on smartphone has never been studied for the control of postoperative pain.
Safety and Efficacy of ERAS Therapeutic Protocol for Complicated Appendicitis in Children
Enhanced Recovery After SurgeryAppendicitis2 moreComplicated appendicitis in pediatrics is frequent, potentially serious and complex to manage. The implementation of a ERAS model would allow optimizing perioperative care, offering a shorter hospital stay, reducing complications associated with medical care and costs, although adequate multidisciplinary management is necessary. The objective of the study is to evaluate the safety and efficacy of the application of a ERAS therapeutic protocol and compare them with the safety and efficacy of conventional management in children with complicated appendicitis.
