Active clinical trials for "Pyloric Stenosis"

Malignant gastric outlet obstruction is a very disabling complication of patients with gastric, duodenal, ampullary, pancreatic, or bile duct cancer and worsens their prognosis. Current treatments have reported a similar complication rate and higher mortality in surgically treated patients. Recently, the creation of endoscopic ultrasound-guided gastroenterostomy (EUS) has shown promising results in these patients. The aim of this research is to determine the safety and efficacy of EUS-guided gastro-enterostomy in the treatment of patients with malignant gastric outlet obstruction.

Malignant gastric outlet obstruction (GOO) results from the mechanical obstruction of the duodenum or distal stomach from an underlying cancer. The consequences of GOO are abdominal pain, nausea, vomiting, anorexia, inability to maintain an oral diet and weight loss, with associated poor quality of life and inability to continue with cancer therapy. The aim of this study is to compare the clinical outcomes between surgical gastrojejunostomy and EUS-guided gastrojejunostomy in patients with malignant gastric outlet obstruction.

The primary objective of this open-label pilot study is to investigate whether an endoscopically placed lumen apposing metal stent is an effective alternative to surgery in patients that have a clear indication for reversal of their gastric bypass.

This study is intended to investigate whether roux-en-y bypass surgery is superior to conventional loop gastrojejunostomy for Malignant gastric outlet obstruction in terms of tolerance to solid food intake. We hypothesize that roux-en-y bypass will be associated with improved solid food intake in the first 30 days after surgery.

EUS-guided drainages has been largely widespread during the last 10 years, even thanks to the advent of dedicated devices, such as lumen apposing metal stents (LAMSs). Above all, EUS-guided choledochoduodenostomy (EUS-CD) is to date considered a valuable option of treatment in case of distal malignant biliary obstruction in case of failure of endoscopic retrograde cholangiopancreatography (ERCP) due to the presence of a gastric or duodenal obstruction, unreachable papilla in case of altered anatomy, infiltrated papilla or failure of deep cannulation of the common bile duct. This modality of drainage demonstrated satisfying results, with high rate both of technical and clinical success with acceptable rate of adverse events. When the distal malignant biliary obstruction is associated to signs and symptoms of gastric outflow obstruction (GOO) due to the presence of a gastric or duodenal stenosis, a concomitant or subsequent palliation of the stenosis may be required. Recently, EUS-guided gastroenterostomy (EUS-GEA) has been introduced for the palliation of GOO, showing good results although technically challenging. To date, endoscopic treatment in case of GOO, enteral stenting and EUS-GEA are possible alternatives. However, available data demonstrated that EUS-GEA seems to be superior to enteral stenting in terms of rate of reinterventions during long-term follow-up, especially when life expectancy is superior to 6 months. However, data are lacking regarding which is the best strategy when GOO is associated to distal malignant biliary obstruction, especially when EUS-CD is performed. This is an hot topic, as it has been supposed that EUS-CD has higher rate of adverse events, especially food impaction, when a duodenal stenosis is present. The aim of our study, therefore, is to perform a retrospective multicenter study collecting all consecutive patients affect by distal malignant biliary obstruction drained using EUS-CD, with associated GOO treated with concomitant or subsequent duodenal stenting or EUS-GEA, in order to evaluate clinical efficacy, long term outcomes and severity of adverse events.

Gastric outlet obstruction (GOO) is a common complication of luminal malignancies which is associated with substantial morbidity. Palliation of GOO has traditionally been through the surgical bypass of the obstructed lumen by creating an opening between the stomach and small intestine. However, In recent years, a less invasive approach, i.e. endoscopic stenting, has gained wide acceptance to treat unresectable malignant gastric outlet obstruction. In this study, the investigators are going to compare the safety and efficacy of the two different endoscopic techniques including Endoscopic ultrasonography-guided gastroenterostomy (EUS-GE) and enteral stenting (ES).

Gastric outlet obstruction (GOO) occurs commonly in malignancies involving the periampullary region (cancers originating in the head of the pancreas, duodenum, bile duct, or ampulla) or the distal stomach. GOO not only causes debilitating symptoms such as nausea, vomiting, inability to tolerate oral intake, and prevents adequate nutritional intake. Therefore, providing therapy for GOO is imperative to improve the quality of life, and nutritional status of these patients, as well as allow them to continue receiving their cancer treatment

A prospective, multi-center, single-arm study for unresectable malignant gastric outlet obstruction with EUS-guided double-balloon-occluded gastrojejunostomy bypass (EPASS)

The purpose of this study is to compare two different ways of placing breathing tubes for surgery. Both ways are used currently to place breathing tubes and are safe and effective. This study seeks to determine if one way is better than the other for infants with pyloric stenosis.

This registry aims to analyze long-term outcomes of therapeutic EUS (T-EUS) procedures, as well as to describe clinical and technical variables potentially predicting clinical success or adverse events, for a better selection of ideal candidates.
