Information for Patients

Colonic Diseases

Also called: Large intestine diseases

Your colon, also known as the large intestine, is part of your digestive system. It's a long, hollow tube at the end of your digestive tract where your body makes and stores stool. Many disorders affect the colon's ability to work properly. Some of these include

  • Colorectal cancer
  • Colonic polyps - extra tissue growing in the colon that can become cancerous
  • Ulcerative colitis - ulcers of the colon and rectum
  • Diverticulitis - inflammation or infection of pouches in the colon
  • Irritable bowel syndrome - an uncomfortable condition causing abdominal cramping and other symptoms

Treatment for colonic diseases varies greatly depending on the disease and its severity. Treatment may involve diet, medicines and in some cases, surgery.

  • Angiodysplasia of the colon
  • Colitis
  • Colonoscopy
  • Hirschsprung disease
  • Intestinal ischemia and infarction
  • Large bowel resection

A fistula is an abnormal connection between two parts inside of the body. Fistulas may develop between different organs, such as between the esophagus and the windpipe or the bowel and the vagina. They can also develop between two blood vessels, such as between an artery and a vein or between two arteries.

Some people are born with a fistula. Other common causes of fistulas include

  • Complications from surgery
  • Injury
  • Infection
  • Diseases, such as Crohn's disease or ulcerative colitis

Treatment depends on the cause of the fistula, where it is, and how bad it is. Some fistulas will close on their own. In some cases, you may need antibiotics and/or surgery.

Small Intestine Disorders

Your small intestine is the longest part of your digestive system - about twenty feet long! It connects your stomach to your large intestine (or colon) and folds many times to fit inside your abdomen. Your small intestine does most of the digesting of the foods you eat. It has three areas called the duodenum, the ileum, and the jejunum.

Problems with the small intestine can include:

  • Bleeding
  • Celiac disease
  • Crohn's disease
  • Infections
  • Intestinal cancer
  • Intestinal obstruction
  • Irritable bowel syndrome
  • Ulcers, such as peptic ulcer

Treatment of disorders of the small intestine depends on the cause.

  • Duodenal atresia
  • EGD - esophagogastroduodenoscopy
  • EGD discharge
  • Enteritis
  • Enteroscopy
  • Meckel's diverticulectomy
  • Small bowel bacterial overgrowth
  • Small bowel resection
  • Upper GI and small bowel series
