Filter by:The aim of this study is to compare the efficacy of a proton pump inhibitor (lansoprazole) and a histamine-2 receptor antagonist (famotidine) in preventing recurrent ulcer bleeding in patients with a history of H. pylori-negative idiopathic peptic ulcers.
The investigators previously showed that the use of a high-dose intravenous PPI regimen after endoscopic control of bleeding from peptic ulcers reduced rate of recurrent bleeding, decreased the need for endoscopic and surgical interventions and in general improved patients' outcomes. A trend towards reduced mortality associated with the use of high-dose intravenous PPI was also observed. Recent clinical trials from Asia have provided evidence that high-dose oral PPIs are associated with a reduction in rebleeding. Current meta-analysis suggests that both high dose (intravenous) and low dose (oral) PPIs effectively reduce rebleeding vs placebo. However, there has been no clinical study to compare IV infusion to oral PPI in this patient population. The purpose of this clinical study is to compare the efficacy and safety of intravenous and oral Esomeprazole in patients with peptic ulcer hemorrhage who are at risk for recurrent bleeding. The investigators hypothesize that using IV infusion is superior to oral PPI.
The aim of this study is to determine if early angiographic embolization can forestall recurrent bleeding in selected high risk ulcers after their initial endoscopic control; to validate prospectively the investigators proposed in selecting high risk ulcers for recurrent bleeding in spite of maximal endoscopic control and profound acid suppression using high dose intravenous infusion of proton pump inhibitor; to characterize the nature of bleeding arteries in severely bleeding peptic ulcers and determine the efficacy of angiographic embolization in the prevention of recurrent bleeding and to establish safety profile of angiographic embolization as an early elective treatment to bleeding peptic ulcers.
Proton Pump Inhibitors (PPI) can prevent the recurrence of peptic ulcer in clopidogrel users.
Peptic ulcer bleeding is a common disorder. Despite optimal endoscopic and medical treatment, there is a high risk of rebleeding and high mortality. In this study the investigators examine whether combined endoscopic haemostasis and angiographic embolization resolves in a better outcome than the traditional use of endoscopic haemostasis alone. The study is a randomised controlled trail.
This study is being done to see if a new approach to repair perforated ulcers in the stomach (holes in the stomach) or the first part of the intestine is possible. Traditionally, either open operations (large single incision) or laparoscopic operations (multiple small camera-guided incisions) have been used to repair perforated ulcers. Over the last ten years, some surgeons have used endoscopic equipment to assist them with performing the procedure. It is unknown if perforated ulcer repair can be done using an endoscope as the main instrument (a flexible tube with a video camera inserted into the stomach through your esophagus) to "patch" or plug the perforation. We will patch the perforation using a standard method which uses tissue from outside the stomach. A laparoscopic camera will also be used to assist our view. This study is intended to be a feasibility study to demonstrate the endoscopic technique can be safely performed Hypothesis: The primary outcome is successful completion of the procedure.
A common late complication after gastric bypass surgery is marginal ulceration that is defined as ulcers at the margins of the gastrojejunostomy, mostly on the jejunal side. Most marginal ulcers respond to medical therapy and complicated or complex ulcer disease warrants operative intervention; specifically, perforated, penetrated, obstructing, bleeding and intractable marginal ulcers require surgical intervention. Diverse operative strategies for addressing perforated marginal ulcers after gastric bypass have been described including I) Omental (Graham) patch repair, II) Revision of gastrojejunostomy, III) Irrigation and drainage, IV) any previous procedure with truncal vagotomy, V) Esophagojejunostomy, and VI) Reversal. We formally analyze our experience with the laparoscopic resection and repair of acutely perforated marginal ulcers after Roux-en-Y gastric bypass (RYGB), with or without concomitant resolution of technical risk factors for marginal ulceration.
The purpose of this study is to determine the feasibility, safety, and efficacy of revision gastroplasty along with other adjunct procedures in the treatment of intractable / chronic marginal ulcers after Roux-en-Y gastric bypass. A secondary aim is the identification of good and poor outcome predictors after revisional strategies for intractable or chronic marginal ulcer.
The objective of this study is to identify the incidence rate; describe the risk factors, clinical presentation, and endoscopic treatment; assess the morbidity, mortality, and overall performance of the management of patients with actively bleeding marginal ulcers after Roux-en-Y gastric bypass (RYGB) surgery.
The purpose of this study is to investigate whether treatment with a combination capsule of Esomeprazole 40 mg and Aspirin (ASA) 325 mg is bioequivalent (i.e.has the same effect within the body) as these medications taken separately. Two different forms of esomeprazole (tablets and capsules) will be investigated.
