Gastrointestinal Services

Many Americans suffer with gastrointestinal (GI) disorders. They may suffer unnecessarily for years instead of taking simple steps to diagnose and treat their condition.

We diagnose and treat the following:

Bowel incontinence
Cancers of the esophagus, stomach, intestine, and rectum
Colon cancer
GI bleeding
Irritable bowel syndrome
Pancreatic disease
Polyps (tumors)

Methods of Diagnosis and Treatment

Diagnosing a gastrointestinal disorder is an important first step towards treatment. Whittier Hospital Medical Center offers several methods for diagnosis and treatment including:


A colonoscopy gives physicians a view of your lower digestive tract, which is comprised of the colon and rectum.

Physicians may use a colonoscopy to evaluate:

Abdominal pains

Change in bowel movement habits

Determine a cause for blood found in stools

Screen for colon cancer

According to the National Cancer Institute, colorectal cancer is the fourth most common cancer in both men and women. Colonoscopies are an important procedure because they can assist in the screening, prevention, and diagnosis of colorectal cancer. If polyps are found and removed, they may prevent the development of colorectal cancer.

EGD (upper endoscopy):

An EGD, also known as an esophagogastroduodenoscopy, is a procedure that uses a small flexible scope with a camera at the end to look at several passage ways in the body: the small intestine, esophagus, and stomach.

An EGD will allow physicians to identify causes of:


Internal bleeding

Abdominal pain

Problems swallowing


Used to help diagnose disorders of the pancreas, bile ducts, liver, and gallbladder. Stones or other blockages may be removed through the use of stents or extraction.


Recommended as part of a routine screening for older individuals, Sigmoidoscopy is used for viewing the rectum and sigmoid colon for the diagnosis of colon disease.
