Active clinical trials for "Pyloric Stenosis, Hypertrophic"

Pyloric stenosis is a current condition in pediatric surgery. The medical management prior to surgery consists of ionic correction. The nasogastric tube is commonly used to prevent gastric fluid inhalation before surgery, but there is no study on it benefits in this specific use. Other studies suggest that utilization of a gastric tube in pyloric stenosis may increase the duration of the medical treatment. The aim of the study is to evaluate the benefit of the nasogastric tube to prevent respiratory complications. This retrospective, monocentric and descriptive study include all patients hospitalized for pyloric stenosis in the university hospital in Amiens between 2014 and 2021. Patients with and without nasogastric tube prior to surgery are compared, regarding respiratory complications define as use of antibiotic, or oxygen therapy or infection in the lungs X-ray before surgery. The investigators analyze pre-operative data: vomiting, dehydration, time to ionic disorders correction and pain, and also notice the length of hospital stay. Data during hospitalization are analyzed and will be noticed the last medical contact represent by the post-operative consultation.

Pyloric stenosis is a condition that develops in infants and that leads to an obstruction of the channel going out of the stomach. This study is being performed to determine if there is an advantage to the laparoscopic approach or the open approach for the surgical correction of the enlarged pylorus.

Infantile hypertrophic pyloric stenosis (IHPS) is the most common condition for surgical treatment in infant. Traditionally, laparoscopic or open pyloromyotomy are the standard treatments. However, because of severe dehydration, electrolyte disturbance, and malnutrition, these patients have lower tolerance about surgery and recover more slowly than usual. We are going to study the per-oral pyloromyotomy (POP), also named as gastric per-oral endoscopic myotomy (G-POEM), which showed promising results for adult gastroparesis, for a novel application of treating IHPS.

Background: The purpose of this retrospective study is to evaluate surgical outcomes of pyloromyotomy in infants performed under spinal anesthesia compares to general anesthesia. Methods: After receiving the approval of the hospital ethics committee, retrieving, reviewing files and collecting data. Primary outcomes: total operating room time, duration of surgery, pain management and postoperative apnea episodes, time of regaining full enteral feeding. Secondary outcome measures: include cardio-respiratory changes and events, and substantial vomiting postoperatively.

The loss of sodium during infancy causes long term changes in sodium intake. Human research shows that the loss of maternal sodium during pregnancy and neonatal after birth causes an increase sodium intake during childhood. A study that examined sodium intake among infants that were treated with diuretics during the post-natal period found changes in sodium intake compared to controls. In this study we will test sodium intake in young children who have suffered from vomiting due to Hypertrophic Pyloric stenosis during early infancy.
