Active clinical trials for "Pyloric Stenosis"

Covered self-expandable metallic stents (SEMS) have been used to prevent tumor ingrowth, a common complication of uncovered SEMSs. However, they have revealed a high incidence of stent migration in patients with unresectable malignant gastric outlet obstruction (GOO). A conformable covered SEMS was introduced to overcome both stent migration and tumor ingrowth. The aims of this study were to evaluate the clinical outcomes of newly designed conformable covered and uncovered SEMS for palliation of malignant GOO.

This is a retrospective chart review. The objective of the current study is to determine the analgesic efficacy and side effect profile of intravenous acetaminophen when administered to infants undergoing pyloromyotomy. In addition, recovery characteristics of infants who were administered intravenous acetaminophen will be compared to infants who did not receive intravenous acetaminophen to determine if there were any appreciable differences with regard to postoperative discomfort, PACU time, time to oral feeds and hospital discharge.

Gastric outlet obstruction in malignant disease appears when the tumor affects the gastroduodenal area, precluding the passage of food into the small bowel. This condition severely affects the quality of life. In patients with unresectable tumors, there are various available treatments:a surgical bypass connecting the stomach to the small bowel, placing a stent through the tumor to widen the passage and creating a gastrointestinal bypass with a lumen apposing metal stent. These stents are deployed with an echoendoscope, which allows to identify a small bowel loop and to deploy the stent, connecting the small bowel and the stomach. This is called a EUS-guided gastroenterostomy (EUS-GE). EUS-GE is a rather novel procedure. Various techniques to create EUS-GE have been proposed. In this study, the investigators will retrieve data from the procedure and during the thirty following days from consecutive patients undergoing an EUS-GE. The objectives of the study are: To perform a detailed step by step description of the nasobiliary drain assisted EUS-GE To describe the adverse events encountered To describe the proportion of clinical and technical success To assess its impact on the patients' quality of life. To assess the evolution of the oral intake during the first month after the procedure

The objective of this investigation is to compile clinical experience on the use of the Evolution® Duodenal Stent (Cook Ireland), a CE marked device intended for the palliative treatment of duodenal or gastric outlet obstruction and duodenal strictures caused by malignant neoplasms. It is not the goal to change the usual treatment practice of the investigator or the center, nor to collect information on uses outside the product's indications. Patients will be treated as per usual medical practices.

The purpose of this study is to determine if there is an increase in the frequency of formula change in patients with pyloric sctenosis prior to being correctly diagnosed.

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.

Prostaglandin E1 (PGE1) has been used in the medical treatment of ductal dependent critical congenital heart disease in neonates. Apnea/ bradycardia, hypotension, hypokalemia, feeding difficulties, fever, jitteriness are the most important side effects of PGE1. Also gastric outlet has been reported. We aimed to determine effect of PGE1 treatment on pyloric wall thickness in newborn period. In this study, the side effect of increase of pylorus muscle wall thickness will be monitored with weekly ultrasonography. No intervention in the treatment, medical decisions and follow-up of these patients will be made. After reaching the sufficient number of cases (20 cases), increases in the pyloric wall thickness dimensions will be compared with statistical analysis. The number of cases was determined in accordance with the rate of hospitalization in our unit during the determined period (18 months).

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.
