- Patient must have malignant bowel obstruction (MBO) as evidenced by all of the
following:

- Clinical evidence of a bowel obstruction (via history, physical, and radiographic
examination)

- Bowel obstruction below (distal to) ligament of Treitz

- Intra-abdominal primary cancer with incurable disease

- Patients must have malignant bowel obstruction due to an intra-abdominal primary

- A member of the patient's surgical team must indicate equipoise for the benefit of the
surgical treatment for MBO; the surgeon must respond "Yes" to each of the following
questions and sign the S1316 Surgical Equipoise Documentation form for the patient to
be eligible:

- Is surgery for treatment of malignant bowel obstruction (MBO) being considered
for this patient?

- Do you have equipoise (If the treating team finds that an operation is required
[e.g., for acute abdomen], or they would not offer the patient an operation
[e.g., patient is too weak to tolerate surgery], then there is no equipoise)?

- Patients must not have signs of bowel perforation or "acute" abdomen as evidenced by
free air on radiologic imaging or peritonitis on physical exam within 2 days prior to
registration

- Patients must be registered to the study within 3 days after surgical consult for MBO
and prior to any treatment (surgical or non-surgical) for MBO

- Patients must have Zubrod performance status of 0-2 within 7 days prior to
