Active clinical trials for "Appendicitis"

This research programme seeks to combine the resources of NHS primary care, with the leading spectroscopic work in low-magnetic fields of the Wilson Group (Nottingham Trent University) to demonstrate the potential for benchtop Nuclear Magnetic Resonance (NMR) spectroscopy in human clinical pathology. This is an instrument assessment study for point of care viability which will also result in enhanced patient care (pending their consent) in blood screenings and metabolic health data.

The aim of the study which was planned in a randomized controlled experimental design, it was aimed to determine the effect of Transcutaneous Electrical Nerve Stimulation (TENS) application on pain level before mobilization in the postoperative period in children.

Acute appendicitis is the most common cause of abdominal pain requiring surgical intervention. The gold standard test for the diagnosis of acute appendicitis is the CT scan. Despite its effectiveness, the test involves exposure to a high dose of radiation. Using ultrasound to diagnose this condition has been described extensively in the medical literature, and this test has a very high specificity (over 95%), however sensitivity of the test is not as good and varies between 40% and 90%. Major limitations of the Ultrasound test include operator dependency as well as factors such as body habitus of the patient, presence of technical disturbances (artifacts) caused by gas in the large intestine and inadequate cooperation from the patient during the exam. All of these factors may affect the ability to detect sonographic signs of appendicitis. The investigators believe that it is possible to reduce the amount of artifacts caused by the presence of gas in the intestine by filling of the colon with liquid suspension that is routinely given in the investigators' hospital before performing an abdominal CT and performing an additional ultrasound scan to those patients in which the initial ultrasound examination (without any preparation) proved to be equivocal or not diagnostic. The target population for the study is any patient who arrives to the emergency room with complaints of right lower quadrant abdominal pain and it is decided by the referring physician in the ER to start diagnostic workup for suspected appendicitis by performing an ultrasound, if the ultrasound exam proves to be equivocal or not diagnostic and it is decided that the patient needs to continue investigation by performing a CT scan, the patient will receive contrast material orally for approximately 180 minutes and prior to the CT the investigators intend to repeat the ultrasound. The investigators hypothesize that the repeat ultrasound will allow a statistically significant improvement in the detection rate of the appendix.

In this research study, the investigators are trying to find out which of the two methods of injecting local anesthetics (at the site of the belly button cut or by ultrasound guided rectus sheath block) will provide better pain relief and less need for pain medication after surgery in children undergoing single incision laparoscopic appendectomy.

During laparoscopic appendectomy, the base of the appendix is usually secured by an endoloop ligature or the stapler. Non-absorbable plastic hem-o-lok clip was shown as an alternative technique with which laparoscopic appendectomy was done faster and cheaper than the standard techniques. However, biocompatibility of different materials udes in securing the base of appendix is different. It was observed that stapler's clips made by titanium caused the mildest inflammatory reaction and creation of adhesions. Disadvantages of stapler's are their high price. Titanium clips made for the use in laparoscopic appendectomy are safe and effective option in securing the appendicular stump in laparoscopic appendectomy. They have potential advantages over stapler, because they have the same bio compatibility, and their price is lower.

Aimed to the study evaluate the superiority of intracorporal sutures and Hem-o-lok clips in terms of efficiency.

This is a Phase 3, randomized, double-blind, double-dummy, multicenter, prospective study to assess the efficacy, safety, and pharmacokinetics (PK) of eravacycline compared with meropenem in the treatment of complicated intra-abdominal infections (cIAIs).

The goal of this study is to compare the efficacy of PVI irrigation to no irrigation for decreasing postoperative intra-abdominal abscesses in children with perforated appendicitis. Additionally, this study aims to verify the safety profile of dilute PVI for intra-abdominal irrigation.

In children and adolescents (older than 6 years in age) who arrive in the pediatric emergency department because they have been having 5 days or less of abdominal pain (possible appendicitis), will patients who are treated with ketorolac get just as much pain relief as those patients treated with morphine? To answer this research question, we will need a large number of patients in a study. To ensure we have enough patients, we must include many hospitals in different cities and provinces in the same study. Before doing this, though, we must first test a smaller version of the study in our center at McMaster Children's hosptial. The goal of doing this at McMaster first is to make sure or understand: We can enroll enough people in our study over 1 year We can make sure that all the information we collect from patients is complete and nothing is missing Reasons behind why people don't want to participate in the study How satisfied patients and their caregivers were with the study

Single-use medical instruments are intended by the manufacturers for single-use only or for single-patient-use only. Nevertheless, single-use instruments are being reused more than once in many countries around the world. The reasons are mainly economic in developing countries and environmental in developed countries. Concerns are being raised regarding reused instruments sterility and efficacy. Since there is paucity of evidence on safety of multiple use of single-use instruments in surgery, we decided to conduct a clinical study comparing the same surgical procedure performed with new versus reused surgical instrument. We decided to study laparoscopic appendectomy which is a simple and the most common emergency surgery. Instrument under the scrutiny is ultrasonic scalpel which uses high-frequency ultrasound vibration for coagulating and cutting tissue. In the studied period of time, all eligible patients with acute appendicitis will be randomized in two groups, first having surgery with new device and the second having surgery with reused device. Removed appendix will be analyzed for lateral thermal damage and the patients will be followed-up for one month for potential differences in clinical outcomes like pain-killers consumption, length of stay and postoperative complications.
