Endoscopy & Pancreatic-Biliary Disorders

The Section for Endoscopy and Pancreatic – Biliary Disease is devoted to excellence in patient care, research, and education in the fields of gastrointestinal endoscopy and pancreatic disease.

Pancreatic disease includes such disorders as painful masses, sharp, irregular attacks of pain, or an inability to digest food because the pancreas does not produce enough digestive enzymes.

Endoscopes are flexible tubes that can be passed through the mouth or rectum. They allow physicians to see and examine the surfaces of the esophagus (food pipe), stomach, intestine, and colon.

Endoscopic examinations allow physicians to diagnose and treat a variety of intestinal disorders, including abdominal pain, vomiting, and bleeding from the intestinal tract. In addition, benign (non-cancerous) growths of the colon, which can lead to colon cancer, may be detected and removed with the help of an endoscope.

Special versions of the endoscope allow doctors to remove stones from the bile duct (the drainage tube for digestive juices of the liver and gallbladder) and pancreas. A new technique called endoscopic ultrasound allows very clear pictures of the gastrointestinal tract, as well as nearby structures such as the pancreas.

Our section uses a multidisciplinary approach to the care of these patients, meaning that specialists from many different departments work together to plan your care. Specialists in gastroenterology team up with colleagues in surgery, anesthesiology, and radiology.

Swallowing & Esophageal Disorders, including Barretts Esophagus

Cleveland Clinic's Center for Swallowing & Esophageal Disorders offers a coordinated, comprehensive program to treat swallowing and esophageal disorders including Barrett's Esophagus.

The Center's multidisciplinary team includes gastroenterologists, radiologists, thoracic surgeons, neurologists, lung specialists, swallowing therapists, and ear, nose, and throat specialists. Approximately 1,500 patients are seen annually in the Center for Swallowing & Esophageal Disorders, including patients with Barrett’s Esophagus.

Millions of Americans have trouble swallowing or complain of heartburn and acid reflux. These problems may be caused by malfunctioning of the physical structures in the mouth, throat or esophagus, damage to the nerves or muscles coordinating swallowing in these organs, or physical obstruction to these organs.

Acid reflux of stomach contents into the esophagus, throat or mouth can lead to Barrett’s Esophagus and also cause esophagitis and its complications -- chest pain, asthma and breathing problems, or ear, nose and throat complaints including recurrent coughing.

Early diagnosis and intervention are very important. Left untreated, swallowing and esophageal disorders can lead to serious problems.

Fecal Incontinence & Pelvic Floor Dysfunction

In conjunction with the Women's Center for Pelvic Disorders, the physicians in this group evaluate and treat patients with pelvic floor disorders, constipation and fecal incontinence.

Patients have access to a number of treatments for fecal incontinence. To achieve a comprehensive diagnosis, the department utilizes specialized equipment, including ultrasound, to visualize the anal muscles, as well as a dedicated laboratory to evaluate stool incontinence.

Motility Disorders

The Center for Gastrointestinal Motility Disorders diagnoses and treats patients with motor abnormalities of the stomach, small intestine and large intestine (colon). Some of these problems are among the most common health concerns. It's estimated that constipation affects up to 10 million Americans, while approximately 20 million Americans suffer from the opposite problem, fecal incontinence.

The center provides the latest and most comprehensive diagnostic and treatment options for bowel incontinence. If necessary, tests are provided by the Radiology and Nuclear Medicine Departments.

Patients seen at the center are offered medical therapy and biofeedback training exercises, or surgical treatment in the departments of general surgery or colorectal surgery.

In addition to patient care, our staff participates in patient and medical education and clinical research. When appropriate, patients can participate in new treatment trials conducted at Cleveland Clinic.

Anorectal Disease

Descriptions of the conditions commonly seen by specialists in anorectal disease include:


A normal part of the anal anatomy, which helps control bowel motions and gas. When enlarged they may cause discomfort or bleeding and need assessment. Treatment is usually performed in the office with either dietary instructions or application of local hemorrhoid treatments which can be performed at the time of the initial office visit. Larger hemorrhoids may require an operation and, if so, an admission for a day case surgical procedure is arranged.

Anal fissure

Patients have severe pain and sometimes bleeding after passing a bowel motion. Generally, medical treatments can be prescribed in the office. For cases which do not respond to this, a minor surgical procedure can be performed in the office under local anesthetic.

Pilonidal Disease

Patients may develop abscesses between the buttocks, which can be treated in the office and, in rare cases, a general anesthetic required. Definitive later therapy may require a general anesthetic and subsequent wound care.

Anorectal sepsis and fistula

Patients may have severe pain and swelling caused by an abscess in the anal region. The usual initial treatment involves insertion of a small plastic drain under local anesthetic in the office. This gives almost instantaneous relief of symptoms. Some patients with an abscess will later develop a fistula, which requires further treatment. Patients who require further treatment, or patients who have a fistula at their initial visit may require surgery under general anesthetic, which is often arranged at the initial outpatient visit. These fistulas, or abnormal tracts connecting the anal canal or rectum to skin around the anus, sometimes require more than one treatment to heal completely.

Sexually transmitted diseases

Some patients with anal infections may develop pain and/or bleeding. These are treated in the office, sometimes in consultation with the Infectious Disease Department. Some patients may have warts in the anal region, which can usually be treated in the office under local anesthetic.

Malignant tumors

In rare cases, patients develop a swelling or mass in the anal area which is caused by a cancer. Surgeons in this department are experienced at defining the treatment regimes for such tumors which may involve chemotherapy or radiation prior to surgery, or simply proceed with the surgery if needed. The treatment plan is based on individual patient assessment.

Other conditions

Patients may have problems related to the skin around the anus, which can be treated in the office. Patients with discomfort or itch in the anal area can be treated with dietary advice and other suggestions.

Liver Disease

Patient Information

The liver is the body's most complex organ, performing many essential tasks related to the conversion of food to energy (metabolism).

Carbohydrates, fats and proteins from food are transported to the liver from the digestive organs through the portal vein. Nutrients pass into the smaller branches of the portal vein, and seep through the blood vessel walls and into the liver cells. The cells are tiny manufacturing sites where these materials are used to make essential body-building blocks such as bile, cholesterol, immune factors, plasma proteins and albumin.

Through a specialized filtering system, the liver performs the important task of removing toxins and impurities (such as alcohol, drugs and preservatives) from the blood. The liver is also an important site for converting food to energy and storing it as glycogen. Fat-soluble vitamins such as D and E are also stored in the liver.

When liver disease develops, the liver's ability to perform its metabolic, detoxification and storage functions is impaired. When these essential processes are not working as they should, the entire body is affected.

Terms to Help You Understand Liver Disease

Ascites - accumulation of fluid in the abdomen.
Endoscopy - a nonsurgical procedure in which a slim, lighted scope with a camera attached is passed down the throat to aid in diagnosis or treatment.
Jaundice - yellowing of the skin and the whites of the eyes.
Tumor - an abnormal growth of cells which can be benign (non-cancerous) or malignant (cancerous).
Varices - abnormally dilated and lengthened veins.
Shunt - a joining between two veins to reduce pressure and stop bleeding varices.

Common Liver Diseases

More than 100 types of liver disease have been identified. Their common feature is that they all involve damage to the liver that disturbs its ability to function normally. 

Early liver disease may have minimal or no symptoms and often will be passed over as being the flu. As liver disease progresses, characteristic signs develop.

These signs can include a yellow tone to the skin and whites of eyes (jaundice) and brownish urine. In advanced cirrhosis, the abdomen becomes distended with fluid (ascites) and ruptured blood vessels in the stomach and esophagus cause bleeding. The person may vomit blood or pass black stools.

Liver Disease at Cleveland Clinic's Digestive Disease and Surgery Institute

Cleveland Clinic hepatologists specialize in liver disease. They treat a wide range of common and uncommon diseases of the liver and biliary tract including:

  • Chronic viral infections of the liver (hepatitis B link and C link)
  • Alcoholic liver disease
  • Autoimmune liver diseases
  • Acute viral hepatitis
  • Fatty liver associated with obesity and diabetes
  • Inherited disorders (hemochromatosis link, Wilson’s disease and alpha-1- antitrypsin deficiency)
  • Primary biliary cirrhosis (diseases of the bile ducts inside and outside of the liver)
  • Primary Sclerosing Cholangitis

Pioneering Treatments

Cleveland Clinic specialists were among the first in the United States to investigate the use of interferon for chronic viral hepatitis. Their research remains at the forefront of antiviral therapy advances today as they investigate many new and experimental treatments.

Some of these therapies are available for patients participating in clinical trials.

Cleveland Clinic hepatologists also are well-versed in new innovative and comprehensive therapies for any stage of liver disease including all complications of cirrhosis. As a result, Cleveland Clinic is a regional center for referral of patients dealing with cirrhosis and its complications.

To help patients, Cleveland Clinic physicians:

  • Are prepared to receive and evaluate patients with severe liver failure, readying them for liver transplants if necessary.
  • Use sophisticated monitoring equipment to improve patient survival in the interim before transplant, particularly in patients with significant tendencies to bleed.
  • Collaborate as surgeons work with hepatologists to offer Ohio’s largest volume of liver transplants, including deceased donor and living donor transplantation.

Fighting Liver Disease

Medical, surgical and radiological specialists cooperate closely to diagnose and treat all types of liver disease and disorders, including liver masses.

Cleveland Clinic surgeons have extensive experience with relatively uncommon hepatobiliary procedures including:

  • Resection of biliary tract cancer
  • Resection of liver cancer
  • Ablation of liver cancers using a radio frequency probe

Cleveland Clinic radiologists offer a sophisticated array of diagnostic and therapeutic options for liver disease. They offer a transjugular intrahepatic portal systemic shunt (TIPS), which is a procedure in which a stent (a tubular device) is placed in the middle of the liver to relieve the pressure in the portal vein. They also employ an approach to treating liver cancers called chemoembolization.

Stomach Disorders

Stomach disorders include indigestion, abdominal pain, and gas, among others. Just about everybody at one point or another will have some kind of stomach or abdominal pain. Most causes are not serious. However, abdominal pain can also be the sign of a serious illness, and it is important to recognize which symptoms are severe and when to call a doctor.

If your abdominal pain is severe, or if you have any of the following symptoms, contact your doctor as soon as possible:

  • Nausea, fever, or cannot keep food down for several days
  • Bloody stools
  • Difficulty breathing
  • Vomiting blood
  • The pain occurs during pregnancy.
  • The abdomen is tender to the touch.
  • The pain is the result of an injury to the abdomen.
  • The pain lasts for several days.

Treating abdominal pain depends on its cause. Options include medications, antibiotics for infections, or changes in diet to treat abdominal pain caused by certain foods or beverages.

Gallbladder and Bile Duct Disorders

The gallbladder is an organ that resembles a small pear. The gallbladder stores and dispenses bile, a fluid that is produced by the liver and helps digest fats.

The gallbladder is connected to the liver and the intestine by a group of ducts, including the common bile duct, the hepatic duct, and the cystic duct. When you eat, the gallbladder sends bile through the common bile duct into the intestine to help you digest the food.

One of the most common disorders of the gallbladder is gallstones. Gallstones can be tiny (the size of a grain of sand), or may be as large as a golf ball. Depending on the symptoms, people who have gallstones may not need treatment, or they may need to take medication or have surgery to remove their gallbladder. If the stones are in the bile ducts, they usually need to be removed by endoscopy (flexible tubes that can be passed through the mouth or rectum).

Other diseases of the gall bladder and bile duct include cholangitis (infection of the bile duct) and cholecystitis (infection of the gallbladder).

Disorders of the Colon

The colon, also known as the large intestine, is part of the digestive system. The colon’s main job is to process the liquid stool it receives into a manageable amount of solid stool that the body eliminates.

Disorders of the colon include inflammatory bowel disease (Crohn’s disease and ulcerative colitis) and colon cancer.

Crohn’s disease is a long-term illness in which the bowel becomes inflamed and ulcerated (marked with sores). Symptoms include diarrhea, weight loss, and abdominal pain and tenderness.

Ulcerative colitis affects only the large intestine. The main symptom of ulcerative colitis is diarrhea, which usually becomes bloody.

Cancer of the colon and rectum is a major health problem in America today. The good news is that colon cancer is a preventable disease. A colonoscopy can prevent colorectal cancer by finding and removing polyps, small growths in the lining of the large bowel that may indicate cancer.

Many diseases of the colon and rectum can be prevented or minimized by seeking medical care when symptoms develop. People who have symptoms of any of these conditions should consult their doctor right away.

Tumors of the GI tract

The gastrointestinal (GI) tract includes the parts of the body that aid in digestion: the mouth, esophagus (food tube), stomach, and intestines.

A tumor is an uncontrolled growth of cells that forms a mass or lump. Tumors of the GI tract are found in such diseases as esophageal cancer, oral cancer, colon cancer, and stomach cancer.

Oral cancer, which includes cancers of the lips, tongue, cheek, floor of the mouth, hard and soft palate, sinuses, and pharynx (throat), appears as a growth or sore that does not go away.

In many cases, you can take certain measures to help prevent some of these cancers. For instance, tobacco use, whether in the form of smoking, chewing, or exposure to second-hand smoke (smoking by others), can cause cancer of the mouth and larynx, esophagus, throat, and many other parts of the body.

Colon cancer is a preventable disease. A colonoscopy can prevent colorectal cancer by finding and removing polyps.
