Brief summary
The purpose of this pilot study is to achieve the collection of safety and efficacy data in patients undergoing left gastric artery embolization for morbid obesity in the United States. As secondary goal, the pilot study seeks to obtain quality of life data. This pilot study is not designed to achieve new indications for this device.
Detailed description
Beadblock will be used intraarterially to occlude in this case the left gastric artery and its branches. The left gastric artery supplies the fundus of the stomach, where it is known that the hormone ghrelin (one of the hormones responsible for appetite) is produced. Ghrelin is a 28 amino acid hunger stimulating peptide and hormone that is produced mainly by P/D1 cells lining the fundus of the stomach and epsilon cells of the pancreas. Ghrelin has emerged as the first identified circulating hunger hormone. Ghrelin is also the only known circulating orexigen, or appetite enhancing hormone. Left gastric artery embolization may be a minimally invasive alternative to the current surgical treatment of gastric bypass or reduction surgery. These treatments have known serious complications including anastomotic leaks, bowel obstruction, paralytic ileus, deep vein thrombosis, pulmonary embolism, gastrointestinal bleeding, dumping syndrome, and anesthesia risks resulting in morbidity and mortality. Literature review for gastric artery embolization Transarterial embolization is a common interventional procedure used to treat a variety of medical conditions. In the image-guided procedure, an embolic, or obstructive, agent is inserted through a catheter and placed inside an artery to prevent blood flow in an artery or to a specific area of the body. Types of embolic agents include beads, coils, gel foam,as well as other materials and devices. Gastric artery embolization has been used since the 1970's to treat life threatening gastric hemorrhage. This is commonly accepted as standard of care and has been life saving for thousands of patients. It is even deemed to be effective enough to be used empirically in the setting of angiographically negative life threatening hemorrhage (as a reflection of its safety margin). Recent animal studies over the past several years in porcine and canine models have shown that gastric artery embolization results in the suppression of ghrelin levels and weight loss. Arepally, et al. (2008) first described the technique of gastric artery embolization to reduce weight gain. In a controlled study, he used sodium morrhuate within a porcine model with resultant lower ghrelin levels and significantly blunted weight gain (in otherwise rapidly growing young swine). Paxton, et al. (SIR abstract in 2012, later published in 2013 and 2014) described the technique of 40 micron microsphere particle embolization in a similar porcine model that also resulted in lowered ghrelin levels and reduced weight gain. Also noted there was no duodenal upregulation for ghrelin. Bawudun et al. (2012) described a technique of left gastric embolization using mixture of bleomycin and lipiodol versus polyvinyl alcohol 500-700 micron particles to create weight loss in a canine model without gastric ulceration. In addition, he demonstrated significant reduction in subcutaneous fat and plasma ghrelin. Kipshidze, et al. (2013) performed the first in man study reported at the annual meeting of the American College of Cardiology that showed an average of 45lbs of weight loss in 6 months and reduced ghrelin levels in 5 patients with no complications (with endoscopic follow-up) in this small series using BeadBlock 300-500 micron particles. According to personal correspondence with the author of this study the weight loss is sustained for at least 1 year with no complications in these 5 patients. He also noted that an additional 7 patients have been treated without complications. A recent retrospective case control study presented at the 2013 Radiological Society of North American annual meeting found that there was an average of 7.9% decrease in body weight (at 3 months) in 15 patients who underwent left gastric artery embolization for life threatening hemorrhage compared to 1.2% (P=0.001) for age matched controls (who underwent embolization other than the left gastric artery for upper gastrointestinal bleeding).

DEVICEBeadBlock 300 - 500 Micron
Beadblock will be used intraarterially to occlude the left gastric artery and its branches. The left gastric artery supplies the fundus of the stomach, where it is known that the hormone Ghrelin (one of the hormones responsible for appetite) is produced.

Willing, able and mentally competent to provide written informed consent (to ensure that all study subjects demonstrate an understanding of the risks of the procedure and also participate in the informed consent). Subjects who have failed previous attempts at weight loss through diet, exercise, and behavior modification (as it is recommended that conservative options, such as supervised low calorie diets combined with behavior therapy and exercise, should be attempted prior to enrolling in this study).

QOL: Averaged SF-36v2 MCS at 12 Months Post-Procedure
The mean of participant's SF-36 Version 2 MCS at 12-months post-procedure, ranging from 0-100; higher scores indicate better health status. The SF-36v2 contains 8 sections total which are each calculated into individual scale scores. A z-score is then determined for each scale score by subtracting the mean scale score of a sample of the national general population from the scale score of the individual participant being analyzed. Each of the 8 z-scores are then multiplied by the MCS scoring coefficient, added together, multiplied by 10 and added to 50.
