Gastroenterology Tests & Procedures in Eau Claire

Overview

Anal manometry is a test that uses a narrow, flexible tube that is inserted into the anus and rectum. A small balloon at the tip of the catheter may be expanded. This test helps measure the tightness of your anal sphincter and the sensitivity and functioning of your rectum.

Why it's done

An anorectal manometry helps to evaluate patients with constipation or fecal incontinence.

Overview

This procedure uses a tiny wireless camera to take pictures of your digestive tract. The camera sits inside a vitamin-sized capsule that is swallowed. As the capsule travels through your digestive tract, the camera takes thousands of pictures that are transmitted to a recorder you wear on a belt around your waist or over your shoulder.

Why it's done

It is used to diagnose diseases of the small intestine including Crohn's disease, celiac disease and other malabsorption disorders; benign and malignant tumors of the small intestine; vascular disorders; and medication-related small bowel injury.

Overview

A colonoscopy is an exam used to detect changes or abnormalities in the large intestine (colon) and rectum. If necessary, abnormal growths called polyps can be removed during a colonoscopy.

Why it's done

Your doctor may recommend a colonoscopy to:

• Investigate certain worrisome signs and symptoms
  A colonoscopy can help your doctor explore possible causes of rectal bleeding, chronic diarrhea, iron deficiency anemia , etc.
• Colon cancer screening
  If you're age 45 or older and at average risk of colon cancer — you have no colon cancer risk factors other than age — or your last colonoscopy was normal 10 years ago, your doctor may recommend a colonoscopy every 10 years to screen for colon cancer.
• Colon cancer and polyp surveillance
  If you have had polyps before, your doctor may recommend a follow-up colonoscopy to look for and remove any new polyps. This is done to reduce your risk of colon cancer.

Overview

Endoscopic mucosal resection (EMR) is a procedure to remove large polyps and very early-stage cancer from the lining of the digestive tract. It can also be used to help determine if a cancer has spread to tissues beneath the digestive tract lining. Endoscopic mucosal resection is performed with a long, narrow tube equipped with a light and video camera. During EMR of the upper digestive tract, the doctor passes this tube (endoscope) down your throat into your esophagus, stomach or upper part of the small intestine (duodenum). To reach the colon, the doctor guides the tube up through the anus. The doctor then inserts instruments through the tube to perform the procedure.

Why it's done

Endoscopic mucosal resection is a less invasive alternative to surgery for removing abnormal tissues from the lining of the digestive tract. Your doctor may recommend the procedure to remove certain early-stage cancers or precancerous growths.

Some of the conditions that EMR has been used to treat include:

• Barrett's esophagus
• Cancer of the small intestine (duodenum)
• Colon polyps
• Colorectal cancer
• Esophageal cancer
• Stomach (gastric) cancer

Overview

ERCP is a procedure that examines the ducts that drain the liver, gallbladder and pancreas. The test combines the use of a flexible, lighted scope (endoscope) with X-ray pictures. It is used to provide important information that cannot typically be obtained by other diagnostic examinations, such as an abdominal ultrasound, CT scan or MRI.

Why it's done

ERCP may be used to remove or crush bile duct and pancreatic duct stones, as well as treat obstructive jaundice (bile duct blockage caused by tumor or stone).

Overview

Endoscopic ultrasound (EUS) is a minimally invasive, using a special endoscope and high-frequency sound waves to produce detailed images of the lining and walls of your digestive tract and chest, nearby organs such as the pancreas and liver, and lymph nodes. When combined with a procedure called fine-needle aspiration, EUS allows your doctor to sample (biopsy) fluid and tissue from your abdomen or chest for analysis. EUS with fine-needle aspiration can be a minimally invasive alternative to exploratory surgery.

Why it's done

EUS is used to further evaluate findings from imaging tests such as a CT scan or MRI. EUS may help in the evaluation of lymphoma, pancreatitis, sarcoidosis, neuroendocrine tumors, and cancers of the esophagus, lung, pancreas, ampulla and rectum.

Overview

This test is done by inserting a catheter in the nose to the esophagus to measure the pressure and pattern of muscle contractions in your esophagus. Abnormalities in the contraction and strength of the sphincter in the esophagus will be evaluated and identified with this test.

Why it's done

The esophagus is a muscular tube connecting your throat to your stomach. With each swallow, the esophagus muscle contracts and pushes food into the stomach. At the lower end of the esophagus, a valve (a special sphincter muscle) remains closed except when food or liquid is swallowed or when you belch or vomit. When you have problems with heartburn, pain or difficulty swallowing, an esophageal manometry test may be prescribed by your doctor.

Overview

Also known as esophagogastroduodenoscopy (EGD) or gastroscopy, this procedure uses a small, flexible instrument to examine the esophagus, stomach and upper small intestine.

Why it's done

An EGD is done to look for causes of abdominal pain, difficult or painful swallowing, gastrointestinal bleeding, nausea and vomiting, heartburn and weight loss. During an EGD, your physician can dilate or stretch narrowed areas of the esophagus and stomach; take tissue samples (biopsies) to check for inflammation, infection and cancer; remove growths; remove foreign bodies or food that are stuck in the GI tract; find and treat actively bleeding lesions using medications, cautery or clipping devices.
