Roux-en-Y Gastric Bypass Versus Loop Gastrojejunostomy for Malignant Gastric Outlet Obstruction
What this study is about
This study is intended to investigate whether roux-en-y bypass surgery is superior to conventional loop gastrojejunostomy for Malignant gastric outlet obstruction in terms of tolerance to solid food intake. We hypothesize that roux-en-y bypass will be associated with improved solid food intake in the first 30 days after surgery.

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Provision of signed and dated informed consent form.
- Stated willingness to comply with all study procedures and availability for the duration of the study.
- Male or female aged ≥18 years old.
- Patients with a diagnosis of malignant gastric outlet obstruction. i. Defined as malignant cancer growth of any organ origin in the area of the distal stomach or duodenum preventing normal gastric emptying as determined by symptoms and cross-sectional imaging studies. ii. Symptoms can include abdominal distention, abdominal pain, nausea and vomiting. iii. Cross sectional imaging findings can include tumor growth in the area of the distal stomach or duodenum, gastric distention, fluid filled stomach and decompressed bowel distal to obstruction point.
- Patients deemed to benefit from surgical bypass as opposed to stent placement, by the primary surgeon. This includes assessing participants survival chances and ability to undergo a surgical procedure.
- Patients in a general health status that permits abdominal surgery under general anesthesia. As determined by primary surgeon and anesthesiologist.
Exclusion criteria
- Patients that have had previous treatment for malignant gastric outlet obstruction. a. Including any previous surgery or stent placement for MGOO
- Patients with MGOO deemed to benefit more from endoscopic stent placement rather than surgery for symptom relief. This assessment will be at treating surgeon's discretion.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
