Digestive System Surgical Procedures
Surgery performed on the digestive system or its parts.
Digestive System Neoplasms
Tumors or cancer of the DIGESTIVE SYSTEM.
Digestive System Diseases
Digestive System and Oral Physiological Phenomena
Properties and processes of the DIGESTIVE SYSTEM and DENTITION as a whole or of any of its parts.
Digestive System Physiological Phenomena
Properties and processes of the DIGESTIVE SYSTEM as a whole or of any of its parts.
Digestive System Processes
Biological actions and events that constitute the functions of the DIGESTIVE SYSTEM.
Digestive System Fistula
Generally refers to the digestive structures stretching from the MOUTH to ANUS, but does not include the accessory glandular organs (LIVER; BILIARY TRACT; PANCREAS).
Tumors or cancer of the GASTROINTESTINAL TRACT, from the MOUTH to the ANAL CANAL.
Surgical Procedures, Operative
Digestive System Abnormalities
Congenital structural abnormalities of the DIGESTIVE SYSTEM.
Diagnostic Techniques, Digestive System
Methods and procedures for the diagnosis of diseases or dysfunction of the digestive system or its organs or demonstration of their physiological processes.
Diseases in any segment of the GASTROINTESTINAL TRACT from ESOPHAGUS to RECTUM.
The section of the alimentary canal from the STOMACH to the ANAL CANAL. It includes the LARGE INTESTINE and SMALL INTESTINE.
A nodular organ in the ABDOMEN that contains a mixture of ENDOCRINE GLANDS and EXOCRINE GLANDS. The small endocrine portion consists of the ISLETS OF LANGERHANS secreting a number of hormones into the blood stream. The large exocrine portion (EXOCRINE PANCREAS) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the DUODENUM.
An organ of digestion situated in the left upper quadrant of the abdomen between the termination of the ESOPHAGUS and the beginning of the DUODENUM.
Accumulation of a drug or chemical substance in various organs (including those not relevant to its pharmacologic or therapeutic action). This distribution depends on the blood flow or perfusion rate of the organ, the ability of the drug to penetrate organ membranes, tissue specificity, protein binding. The distribution is usually expressed as tissue to plasma ratios.
Surgical Procedures, Minor
Cause of Death
Tumors or cancer of the STOMACH.
Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
Ambulatory Surgical Procedures
Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Surgical Procedures, Minimally Invasive
Oral Surgical Procedures
Asian Continental Ancestry Group
Surgical Procedures, Elective
Surgery which could be postponed or not done at all without danger to the patient. Elective surgery includes procedures to correct non-life-threatening medical problems as well as to alleviate conditions causing psychological stress or other potential risk to patients, e.g., cosmetic or contraceptive surgery.
Reconstructive Surgical Procedures
Genetic Predisposition to Disease
Otorhinolaryngologic Surgical Procedures
Urologic Surgical Procedures
Surgery performed on the urinary tract or its parts in the male or female. For surgery of the male genitalia, UROLOGIC SURGICAL PROCEDURES, MALE is available.
Obstetric Surgical Procedures
The regular and simultaneous occurrence in a single interbreeding population of two or more discontinuous genotypes. The concept includes differences in genotypes ranging in size from a single nucleotide site (POLYMORPHISM, SINGLE NUCLEOTIDE) to large nucleotide sequences visible at a chromosomal level.
Thoracic Surgical Procedures
National Institute of Diabetes and Digestive and Kidney Diseases (U.S.)
Care given during the period prior to undergoing surgery when psychological and physical preparations are made according to the special needs of the individual patient. This period spans the time between admission to the hospital to the time the surgery begins. (From Dictionary of Health Services Management, 2d ed)
