Adenomatous Polyposis Coli

Alagille Syndrome

Appendicitis - It is an inflammation of the vermiform appendix that may be caused by infection or partial or total obstruction. It is a major cause of intra-abdominal pain, principally attacking those younger than 35 years of age.

Barrett Esophagus

Biliary Atresia - The commonest fatal liver disease in childhood is a congenital deficiency of bile ducts called biliary atresia.

Carcinoma, Pancreatic Ductal - A cancer arising in the epithelial tissue of the skin or of the lining of the internal organs.

Celiac Disease - Diseases of or relating to the abdomen.

Cholangitis - A complication of ulcerative colitis in which the bile ducts develop irregularities and narrowing.

Cholecystitis - Inflammation of the gall bladder.

Cholelithiasis - The formation of gallstones.

Colitis - Inflammation of the lining of the colon.

Colitis, Ulcerative ( --> Colitis) - This is idiopathic (i.e., of unknown cause). It varies from a mild inflammation of the mucosa of the rectum, giving rise to excessive mucus and some spotting of blood in the stools, to a severe, sudden, intense illness, with destruction of a large part of the colonic mucosa, considerable blood loss, toxemia and, less commonly, perforation. The most common variety affects only the rectum and sigmoid colon and is characterized by diarrhea and the passage of mucus.

Constipation - Delayed passage of waste through the lower portion of the large intestine, with sometimes the ultimate discharge of relatively dry, hardened feces from the anus.

Crohn Disease - A chronic inflammatory disease of the intestines, especially the colon and ileum, associated with ulcers and fistulae.

Diarrhea - Abnormally swift passage of waste material through the large intestine, with consequent discharge of loose feces from the anus. Diarrhea may be accompanied by cramping.

Dysentery - Infection of the intestines resulting in severe diarrhoea with the presence of blood and mucus in the faeces.

Dysphagia ( --> Deglutition Disorders) - Difficulty or discomfort in swallowing, as a symptom of disease

Dyspraxia ( --> Apraxia) - Inability to perform particular purposive actions, as a result of brain damage.

Esophageal Achalasia - A condition in which the muscles of the lower part of the oesophagus fail to relax, preventing food from passing into the stomach.

Esophageal Atresia - Absence or abnormal narrowing of an opening or passage in the body.

Esophageal Diseases 

Esophagitis, Peptic

Fatty Liver - Abnormal accumulation of fat in the liver cells, usually as a result of chronic malnutrition.

Fecal Incontinence

Fissure in Ano

Gallstones (--> Cholelithiasis) - The formation of gallstones.

Gastroenteritis

Gastroesophageal Reflux - In healthy individuals, reflux of gastric contents into the esophagus occurs occasionally. This causes the burning sensation behind the sternum that is known as heartburn. It may be accompanied by regurgitation, some of the refluxed material reaching the pharynx where it also may be felt as a burning sensation. Reflux is most likely to occur after large meals, especially if physical activity, including bending, stooping, or lifting, is involved.

Gastrointestinal Hemorrhage

Gastroparesis

Hepatic Vein Thrombosis

Hepatitis - A disease characterized by inflammation of the liver.

Hemorrhoids - Also called PILE, mass formed by distension of the network of veins under the mucous membrane that lines the anal channel or under the skin lining the external portion of the anus.

Hernia, Diaphragmatic - A condition in which part of an organ is displaced and protrudes through the wall of the cavity containing it (often involving the intestine at a weak point in the abdominal wall).

Hernia, Hiatal - The protrusion of an organ, typically the stomach, through the oesophageal opening in the diaphragm.

Hirschsprung Disease - A congenital condition in which the rectum and part of the colon fail to develop a normal system of nerves, and consequently faeces accumulate in the colon following birth.

Ileus ( --> Intestinal Obstruction) - A painful obstruction of the ileum or other part of the intestine.

Inflammatory Bowel Diseases - A widespread condition involving recurrent abdominal pain and diarrhoea or constipation, often associated with stress, depression, anxiety, or previous intestinal infection.

Intestinal Neoplasms

Intestinal Obstruction - Functional or mechanical blockage of the alimentary canal.

Irritable Bowel Syndrome ( --> Colitis ) - The extremely common disorder known as the irritable bowel syndrome is probably due to a disturbance of the motility of the whole intestinal tract.

Lactose Intolerance

Liver Cirrhosis - A chronic disease of the liver marked by degeneration of cells, inflammation, and fibrous thickening of tissue. It is typically a result of alcoholism or hepatitis.

Liver Diseases

Meckel's Diverticulum

Pancreatitis - Inflammation of the pancreas.

Pearson's Syndrome ( --> Pancreatic Diseases)

Peptic Ulcer - A lesion in the lining (mucosa) of the digestive tract, typically in the stomach or duodenum, caused by the digestive action of pepsin and stomach acid.

Peutz-Jeghers Syndrome - Multiple brown freckles on the lips associated with polyps in the small intestine is characteristic of Peutz-Jegher's syndrome.

Proctitis - Inflammation of the rectum and anus.

Rectal Diseases - Diseases affecting the rectum.

Rectal Prolapse

Reye Syndrome - A life-threatening metabolic disorder in young children, of uncertain cause but sometimes precipitated by aspirin and involving encephalitis and liver failure.

Shwachman Syndrome ( --> Pancreatic Insufficiency)

Tracheoesophageal Fistula

Volvulus ( --> Intestinal Obstruction) - Twisting of a portion of the digestive tract on its mesentery (the fold of membrane that attaches the intestine to the posterior abdominal wall), resulting in intestinal obstruction, severe pain, distension of the involved segment, and interference with circulation to the affected area.

Vomiting - Also called EMESIS, the forcible ejection of the stomach contents from the mouth. Like nausea, vomiting may have a wide range of causes, including motion sickness, the use of certain drugs (recreational, illegal, and prescription), intestinal obstruction, disease or disorder of the inner ear, injury to the head, and appendicitis. It may even occur without nausea.

Whipple's Disease

Zenker Diverticulum - An abnormal sac or pouch formed at a weak point in the wall of the alimentary tract.
