Brief Summary
The hypothesis of this study is that an occlusion balloon catheter placed in the stomach via an oral or nasogastric route will be safe and permit tracking of the stomach during radiation therapy.

Outcome Measures
Primary Outcomes (1)
Percentage of participants who undergo successful inflation of the gastric balloon with oral contrast agent, with verification by MR or CT imaging
Completion of follow-up for all participants (estimated to be 1 year)
Secondary Outcomes (2)
Number of grade grade ≥ 2 adverse events that are probably or definitely associated with the balloon inflation
Completion of follow-up (estimated to be 4 weeks)
Translation movement of stomach between CBCT scans with and without balloon insufflation
Day of procedure (Day 1)
Study Arms (1)
Occlusion balloon catheter
EXPERIMENTAL-Each participant will have an embolectomy balloon that is FDA approved for peripheral and neurovasculature temporary occlusion placed by nose or mouth. Anatomical position of balloon will be verified by on-board MR or CT imaging in to assess feasibility of using a duodenal balloon in this population. Participants who are imaged on the MR treatment machine will also be imaged with 4 or 8 frame per second sagittal imaging to assess real-time stomach and balloon respiratory motion. Participants imaged on CT based imaging (i.e. Ethos/Halcyon ring gantry system) will have CBCTs acquired at timed intervals (approximately 5-10 minutes between scans). After imaging, the balloon will be deflated and removed at that time.
Interventions
Eligibility Criteria
You may qualify if:
- Scheduled to receive intra-thoracic or abdominal radiation therapy. It is not required that the stomach be in the radiation field.
- At least 18 years of age.
- ECOG performance status ≤ 1
- Ability to understand and willingness to sign an IRB approved written informed consent document (or that of legally authorized representative, if applicable).
You may not qualify if:
- Prior trauma or surgical intervention that would alter the anatomy of the upper airs (nasogastric route), esophagus or stomach.
- Previous complete or partial surgical resection of the esophagus, stomach, or duodenum.
- Presence of implantable devices (e.g., automatic internal cardiac defibrillator, cardiac or gastric pacemaker).
