Active clinical trials for "Gastroparesis"

This is a prospective registry of all patients who endoscopic submucosal dissection (ESD), per-oral endoscopic myotomy (POEM) and gastric per-oral endoscopic myotomy (G-POEM) using ConMed Electrosurgical unit for submucosal Dissection at Baylor St Luke's Medical Center. Collected information includes; procedure technical success rate, duration, periprocedural complications and ease of use.

The aim of the present prospective study was, first, to verify the correlation between biliary colonization and postoperative infectious complications, and secondarily to asses morbidity and mortality for patients who underwent pancreaticoduodenectomy. The hypothesis is that a proportion of post-operative infections after pancreaticoduodenectomy is due to bacteria that colonize the bile ducts during the preoperative period.

The purpose of this research is to further study the relationship between gastroparesis (GP) (a condition in which the stomach cannot empty itself of food in a normal fashion) and functional dyspepsia (FD) (frequent symptoms of indigestion that have no obvious cause).

The purpose of this research is to determine if an investigational device called the 13C-Spirulina Gastric Emptying Breath Test (GEBT), can accurately diagnose gastroparesis (delayed emptying of the stomach) in patients with Cystic Fibrosis (CF).

Global osteopathic manual treatments will decrease the severity score of the Gastroparesis Cardinal Symptom Index tool of patients with idiopathic gastroparesis. In this longitudinal controlled pre-test post-test group design, subjects with idiopathic gastroparesis (IG) will be utilized to see if global osteopathic manual treatments can decrease their symptoms. Patients with IG suffer from varying degrees of nausea, vomiting and abdominal pain secondary to delayed gastric emptying. There is no known cause for people suffering from IG. According to the power analysis, the population will be utilized as the experiment group and the control group. The measuring tool to be used is the Gastroparesis Cardinal Symptom Index (GCSI) which is the most widely used symptom score questionnaire for gastroparesis. The subjects in the population will each fill out the GCSI initially and again after an two (2) week period to measure their symptoms during a control period. The same subjects will then be treated with global osteopathic manual treatments one (1) treatment every two (2) weeks for four (4) weeks (day 1, 14, and 28). The GCSI will be filled out on the day of the first (1st) treatment (which is the last day of the control period) and then two (2) weeks after the last treatment (day 42). In order to reject the null hypothesis, with a p value of < 0.05 and a power of 0.8, a minimum of ten (10) subjects in the treatment group is required with a treatment effect of 1 or more. A 'Treatment effect of 1' is defined by Cohen's d, where d = mean difference/standard deviation. It is expected that the results will show improvement of symptoms through the data collected from the GCSI questionnaires in the treatment group. The results of this study could be significant and contribute to the osteopathic community validating the effectiveness of traditional osteopathic manual therapy as well as giving non-invasive options to people suffering from the disease since those who struggle with it have minimal treatment options--medicines with significant side effects, full or total stomach removal or gastric electrical stimulator implants.

Surgical resection in periampullary cancer using pancreaticoduodenectomy is the most important modality in the treatment. In the past, pancreaticoduodenectomy was associated with high morbidity and mortality. However, with the advances in techniques, including perioperative patient management, development of antibiotics, diagnostic radiology, and interventional treatments, pancreaticoduodenectomy is now considered a safe and feasible operation. Postoperative complication rates are reported to be in 10 to 20% in experienced hospitals and operation related mortality is at about 1%. Therefore, surgical treatment for periampullary cancer is actively considered. However, postoperative complications, such as postoperative pancreatic fistula, (POPF) delayed gastric emptying, intraabdominal abscess, and postoperative bleeding, are still serious complications. Among these complications, delayed gastric emptying is considered less critical. However, delayed gastric emptying (DGE) can cause poor oral intake, which in turn, may lead to delay in recovery of postoperative nutritional state and in severe cases, requires insertion of levine tube and long-term fasting. There have been many hypotheses for cause of DGE after pancreaticoduodenectomy, but definite cause have not been discovered yet. With the introduction of pylorus-preserving pancreaticoduodenectomy (PPPD), incidences of DGE were initially reported to have increased. However, results of most randomized comparative studies had concluded that PPPD and PD have no significance in occurence of DGE. One hypothesis for cause of DGE we present here has to do with anatomic positioning of anastomosis site, especially pancreatojejunostomy (PJ) and duodenojejunostomy (DJ), after PPPD. Reconstruction after PPPD positions PJ and DJ close to each other. PJ site is often associated with one of postoperative complications, POPF. POPF may create inflammation around PJ site and pancreatitis, which may lead to severe adhesion around PJ as a secondary change. This adhesion and inflammation may cause DJ, which is located near PJ, to be pulled towards PJ site. When DJ is pulled towards PJ site, distal DJ site can become angulated and gastric contents may not beadle to pass easily. Gastric contents may be stagnated in stomach and thereby causing DGE. Therefore, in this study, we will fixate DJ on transverse colon using sutures, and prevent possibility of angulation of DJ. This additional procedure may reduce occurence of DGE.

The gastric emptying of 400 ml 12.6% carbohydrate rich drink is investigated in elderly women, age 75-100, with acute hip fracture. The emptying time will be assessed by the paracetamol absorption technique, and lag phase and gastric half-emptying time compared with two gender-matched reference groups: elective hip replacement patients, age 45-71, and healthy volunteers, age 28-55.

To allow the use of domperidone by patients with gastrointestinal disorders who have failed standard therapy.

To expand a registry of patients for the study of the epidemiology, etiology, and degree of morbidity associated with gastroparesis.

This study aims to evaluate whether the incidence of delayed gastric emptying (DGE) can be reduced by proximal Roux-en-y gastrojejunal anastomosis in comparison with the standard gastrojejunal anastomosis in pylorus-resecting pancreaticoduodenectomy (PrPD).
