Partially Covered Versus Uncovered Pyloro-duodenal Stents for Unresectable Malignant Gastric Outlet...

Unresectable Malignant Gastric Outlet Obstruction

To compare the efficacy of a novel partially covered (PC) versus uncovered (UC) pyloro-duodenal stents (DS) in unresectable malignant gastric outlet obstruction. We hypothesize that the use of PCDS could reduce the re-intervention rates when compared to UCDS.

Post-Operative Impact of Nasogastric Tubes on Rates of Emesis in Infants Diagnosed With Pyloric...

Pyloric Stenosis

The overall objective of this research study is to determine the effect of a pre-operatively placed nasogastric tube compared to no nasogastric tube, on post-operative emesis rates and postoperative length of stay in infants with a primary diagnosis of pyloric stenosis treated with pyloromyotomy. This study will also examine the feasibility data of the pilot data to develop estimates of treatment effect of a pre-operative nasogastric tube on post-operative rate of emesis and length of stay to be used to determine the sample size of the definitive trial.

Laparoscopic Versus Open Pyloromyotomy for Infants With Idiopathic Hypertrophic Pyloric Stenosis...

Hypertrophic Pyloric Stenosis

Pyloric stenosis is a condition that develops in infants and that leads to an obstruction of the channel going out of the stomach. This study is being performed to determine if there is an advantage to the laparoscopic approach or the open approach for the surgical correction of the enlarged pylorus.

Magnetic Anastomosis Device Relief of Malignant Gastric Outlet Obstruction

Gastric Outlet Obstruction

The purpose of this study is to determine if the Cook Magnetic Anastomosis Device can be used to safely and successfully create a patent gastrojejunal anastomosis in subjects requiring treatment of gastric outlet obstruction caused by malignancy.

Changes in Cerebral Oxygenation During Laparoscopic Pyloromyotomy

Pyloric Stenosis

A prospective study that will assess the effect of laparoscopy on tissue oxygenation in the patients undergoing a laparoscopic pyloromyotomy at Nationwide Children's Hospital. Tissue oxygenation will be assessed non-invasively using near infrared spectroscopy, a device that is commonly used in our operating rooms to assess cerebral and tissue oxygenation.

Outcome Study of Double Bare Stent for Malignant Gastric Outlet Obstruction

Gastric Outlet Obstruction Due to Malignancy

Self-expandable metallic stents provide effective palliation of malignant gastric outlet obstruction. However, uncovered stent are often associated with re-stenosis caused by tumor in-growth through the stent mesh. The Self-expandable metallic stents which has the design of smaller wire mesh size (double bare stent) were developed and used in Korea. This new design was developed to minimize the re-stenosis of uncovered stent, but the outcome is unknown. The end point of this study is the 8-weeks patency rate after placement of double bare as well as technical and clinical success rates.

Per-oral Pyloromyotomy for Treating Infantile Hypertrophic Pyloric Stenosis

Infantile Hypertrophic Pyloric StenosisPyloromyotomy

Infantile hypertrophic pyloric stenosis (IHPS) is the most common condition for surgical treatment in infant. Traditionally, laparoscopic or open pyloromyotomy are the standard treatments. However, because of severe dehydration, electrolyte disturbance, and malnutrition, these patients have lower tolerance about surgery and recover more slowly than usual. We are going to study the per-oral pyloromyotomy (POP), also named as gastric per-oral endoscopic myotomy (G-POEM), which showed promising results for adult gastroparesis, for a novel application of treating IHPS.

AspireAssist for Palliative Venting Gastrostomy in Malignant Bowel Obstruction Patients

Malignant Small Bowel ObstructionMalignant Gastric Outlet Obstruction

Individuals with cancer causing an intestinal or stomach obstruction often require gastric drainage to prevent symptoms of nausea, vomiting, and to prevent aspiration. This is often achieved by a nasogastric (NG) tube, although prolonged NG tube use can lead to unwanted side effects like ulcers, bleeding, and they are generally uncomfortable. Gastric drainage through the use of a percutaneously placed endoscopic gastrostomy (PEG) tube has been used in people with cancer since the 1980s. This allows relief of symptoms of malignant bowel obstruction though venting of stomach contents. Decompressive PEG tubes are routinely used in individuals with malignant obstruction, although these tubes tend to get clogged from food blocking the tube. The AspireAssist is a weight loss device that allows participants to remove a large amount of the food in their stomachs after each meal to help them to lose weight via an aspiration device attached to the abdominal portion of the tube which allows instillation of water into the stomach, followed by aspiration of the gastric contents into a receptacle or the toilet. The device is placed endoscopically in an identical fashion to a standard PEG tube. Although most commonly used for weight loss, the device is FDA cleared to be used as a venting tube as well. The purpose of this study is to determine if the AspireAssist provides an improved quality of life when compared with a standard venting gastrostomy tube for participants with malignant bowel obstructions.
