A Feasibility Study to Compare the Benefits of Endoscopic Tumor Clip Placement and 3T-MRI Simulation for Accurate Target Volume Definition for Rectal Cancer Patients Undergoing Pre-operative Chemoradiation
This study is looking for a better way to define rectal tumors undergoing pre-operative radiation. MRI scanning generally results in more clear definition of the tumor that CT scanning. Insertion of radio opaque clips in the tumor site could also help to visualize the tumor better for radiotherapy treatment planning. The investigators believe both techniques would help the physician to define to cancer better than using CT scan alone. The investigators also will compare both te...
An simple-blind, randomized study, to evaluate the efficacy and safety of complete closure with clips of mucosal defects after endoscopic mucosal resection (EMR) of large non-pedunculated colorectal lesions (≥ 2 cm) as prophylaxis of delayed bleeding.
Gastric subepithelial masses might harbour gastrointestinal stromal tumors, which should get resected because of their malignant potential. To minimize the associated surgical trauma endoscopic endoluminal resection is favorable. Therefore in the current study endoscopic resection of gastric subepithelial masses is investigated. Since there is a certain risk of perforation due to the procedure, perforations get closed by placement of endoscopic clips (over-the-scope-clip [OTSC]...

Non-variceal acute gastrointestinal bleeding is a common and potentially life-threatening problem. The conventional treatment of this condition is for esophagogastroduodenoscopy (OGD) for haemostasis. Treatment methods include heater probe, clipping and injection of adrenaline. Recently, a new device called the Over-the-scope clip (OTSC) has been device to treat perforations and bleeding in the gastrointestinal tract. Therefore, the aim of the study is to compare between the tr...
The aim of this study is to evaluate the technical feasibility of the new tube placement technology in healthy volunteers and, if proven feasible, in critically ill patients requiring placement of a feeding tube.
There is considerable controversy about the use of nasal packing following endoscopic endonasal resection of pituitary tumors as a necessary treatment amongst Rhinology-Skull Base Surgeons. The justification for the routine use of nasal packing following pituitary surgery is not clear as this practice is not used for equally extensive sinus surgery. Further scientific evidence supporting this practice is lacking, and a recent survey of Canadian surgeons performing this surgery ...
The purpose of this research study is to evaluate placing the radiation therapy markers (Fiducial) by using an endoscopic procedure. The endoscopic procedure is called an Endoscopic Ultrasound (EUS). This is a procedure using a special endoscope that has an ultrasound on the end. The ultrasound will allow the doctor's to see where the radiation therapy markers (Fiducial) is to be placed as outlined by the Radiation Oncologist.
The objective of this feasibility trial is to evaluate the Ethicon Endo-Surgery Endoscopic Suturing System (ESS) for tissue apposition and reduction of the size of a dilated GJ anastomosis in subjects who are regaining weight after successful weight loss following gastric bypass. Post-procedure weight will be followed to assess whether weight loss is resumed. The ESS is an FDA-cleared (510(k)) sterile, single-use, disposable suturing system indicated for endoscopic plac...
A transendoscopic enteral tubing (TET ) tube was inserted into mid-gut through the nasal orifice and fixed on the pylorus wall by one tiny titanium endoscopic clip under anesthesia. This study aimed to evaluate the feasibility and safety of TET in mid-gut .
It is a multicenter prospective observational study including consecutive patients with esophageal tumor or rectum with indication for radiotherapy The main objective of this study is to evaluate the feasibility of fiducial markers placement under EUS guidance. The evaluation criteria are: - Success rate evaluation of the placement of two markers : one in the upper part of the tumor and one in the lower part. Success of the procedure will be evaluated by the ...
The purpose of this study is the evaluation of the success rate of jejunal tube placement comparing the endoscopic versus the electromagnetic method in a comparative ICU patient population. The investigators hypothesized that success rate of the electromagnetic jejunal tube placement will be lower than the success rate of the endoscopic method.
RATIONALE: Pancreas tumor localization makes minimally invasive surgical resection of pancreas tumors very challenging. Recently, an endoscopic ultrasound needle system has been developed which enables fiducial coils to be placed at the precise site of biopsy. INTERVENTION: At time of EUS guided biopsy the fine needle fiducial device will be used to place fiducials in the tumor. During surgery we will assess whether it improves tumor visualization. OBJECTIVES: We aim to...
Background and Study Aims: Biliary strictures are a major cause of morbidity following liver transplantation with an overall incidence between 10 and 30 %. Up to now biliary strictures were dilated subsequently one to three plastic stents with a diameter of eight to ten F were inserted. In general, stents were exchanged in two to three months intervals over one year. In the present prospective controlled study, efficacy and complication rates of balloon dilation have been compa...

There aren't sufficient randomized prospective controlled trials in pediatric population comparing the safety and tolerance of early feeding after PEG placement (3-4 hours). Most patients are fasted for at least 12 hours following percutaneous endoscopic gastrostomy. In order to decrease the period of fasting, inadequate nutritional support, and hospitalization time, the investigators decided to design this study. The additional goal is to establish an optimum standard procedur...

Is DBE(double balloon enteroscopy)-assisted DPEJ(direct percutaneous endoscopic jejunostomy) a viable option in patients who have failed conventional DPEJ placement and who otherwise would require surgical jejunostomy or parenteral nutrition.
Intracorporeal suturing and knot tying during robotic prostatectomy and laparoscopic and robotic renal surgery have historically been considered the most technically challenging and time consuming aspects of these procedures. With improved operative technique as well as the use of innovative surgical devices, vascular control during these surgeries is often less cumbersome as compared with traditional techniques. Current standard methods of hemostasis include the use of clips, ...
The study hypothesis is that placement of LAMS plus an overlapping double pigtail stent for endoscopic transmural drainage of PFCs with solid debris will result in improved drainage and require fewer endoscopic interventions compared to placement of LAMS alone.
1. Biliary duct injury are a relatively frequent complication of hepatobiliary surgery, most comonly laparoscopic cholecystecomy. 2. Prior to the development of more sophisticated endoscopic interventions, repeat surgery was often necessary for the management of biliary leaks. 3. Advances in technique and technology in gastroenterology endoscopy have largely replaced surgery as the first line intervention for biliary leak. 4. Most practices utilize...
