With banding, a surgeon uses rubber bands to tie off blood vessels feeding the portal vein(the vein that carries blood from the digestive organs to the liver). This reduces blood flow and pressure in the portal vein and the likelihood that the vein will rupture or leak fluid.

Bernstein Test

This diagnostic test helps to confirm that symptoms are a result of acid in the esophagus, and is performed by dripping a mild acid through a tube placed in the esophagus.

Biliopancreatic Diversion (BPD)

Both restrictive and malabsorptive, this is a more complicated surgical procedure than the Roux-en-Y gastric bypass procedure. a large part of the lower stomach is removed. The small part of stomach that is left is connected directly to the last part of the small intestine (jejunum).

All bariatric procedures are either malabsorptive, restrictive, or a combination of the two. Malabsorptive procedures change the way the digestive system works. Restrictive procedures are those that severely reduce the size of the stomach to hold less food, but the digestive functions remain intact.


A specific physical trait used to measure or indicate the effects or progress of a disease or condition.


A biopsy is a surgical procedure in which tissue samples are removed from the body for examination under a microscope.


Brachytherapy is radiation treatment with radioactive isotopes (chemical elements), delivered inside the body as close to the cancer as possible, using delivery devices such as wires, seeds, or rods called implants.

Brachytherapy allows for a higher total dose of radiation over a shorter period of time than does external beam therapy. The radiation dose is concentrated on the cancer cells and less damage is done to the normal cells near the cancerous growth.

This procedure may be performed in combination with external beam therapy to help destroy the main mass of tumor cells for certain types of cancer.

It is often used in the treatment of cervical, uterine, vaginal, prostate, or rectal cancer, as well as eye and certain head and neck cancers. However, the therapy may also be used to treat many other cancers.

Blood, Breath, and Stomach Tissue Tests

These diagnostic tests are performed to detect the presence of H. pylori. Some of the tests for H. pylori are not approved by the US Food and Drug Administration (FDA) because they may occasionally give false-positive results; and other tests may give false-negative results in people who have recently taken antibiotics, omeprazole, or bismuth. However, research shows these tests can be accurate in detecting the bacteria.
