Carcinoma in situ of other and unspecified digestive organs (D01) ICD-10-CM

Inflammation of the GALLBLADDER wall in the absence of GALLSTONES.

A dilation of the duodenal papilla that is the opening of the juncture of the COMMON BILE DUCT and the MAIN PANCREATIC DUCT, also known as the hepatopancreatic ampulla.

Tumors or cancer of the APPENDIX.

A worm-like blind tube extension from the CECUM.

A motility disorder characterized by biliary COLIC, absence of GALLSTONES, and an abnormal GALLBLADDER ejection fraction. It is caused by gallbladder dyskinesia and/or SPHINCTER OF ODDI DYSFUNCTION.

Carcinoma that arises from the PANCREATIC DUCTS. It accounts for the majority of cancers derived from the PANCREAS.

Inflammation of the GALLBLADDER; generally caused by impairment of BILE flow, GALLSTONES in the BILIARY TRACT, infections, or other diseases.

The segment of LARGE INTESTINE between the CECUM and the RECTUM. It includes the ASCENDING COLON; the TRANSVERSE COLON; the DESCENDING COLON; and the SIGMOID COLON.

An autosomal recessive genetic disease of the EXOCRINE GLANDS. It is caused by mutations in the gene encoding the CYSTIC FIBROSIS TRANSMEMBRANE CONDUCTANCE REGULATOR expressed in several organs including the LUNG, the PANCREAS, the BILIARY SYSTEM, and the SWEAT GLANDS. Cystic fibrosis is characterized by epithelial secretory dysfunction associated with ductal obstruction resulting in AIRWAY OBSTRUCTION; chronic RESPIRATORY INFECTIONS; PANCREATIC INSUFFICIENCY; maldigestion; salt depletion; and HEAT PROSTRATION.

Tumors or cancer of the DUODENUM.

The shortest and widest portion of the SMALL INTESTINE adjacent to the PYLORUS of the STOMACH. It is named for having the length equal to about the width of 12 fingers.

A storage reservoir for BILE secretion. Gallbladder allows the delivery of bile acids at a high concentration and in a controlled manner, via the CYSTIC DUCT to the DUODENUM, for degradation of dietary lipid.

Diseases of the GALLBLADDER. They generally involve the impairment of BILE flow, GALLSTONES in the BILIARY TRACT, infections, neoplasms, or other diseases.

A process whereby bile is delivered from the gallbladder into the duodenum. The emptying is caused by both contraction of the gallbladder and relaxation of the sphincter mechanism at the choledochal terminus.

Tumors or cancer of the gallbladder.

A human liver tumor cell line used to study a variety of liver-specific metabolic functions.

A malignant neoplasm occurring in young children, primarily in the liver, composed of tissue resembling embryonal or fetal hepatic epithelium, or mixed epithelial and mesenchymal tissues. (Stedman, 25th ed)

Portable or implantable devices for infusion of insulin. Includes open-loop systems which may be patient-operated or controlled by a pre-set program and are designed for constant delivery of small quantities of insulin, increased during food ingestion, and closed-loop systems which deliver quantities of insulin automatically based on an electronic glucose sensor.

Irregular microscopic structures consisting of cords of endocrine cells that are scattered throughout the PANCREAS among the exocrine acini. Each islet is surrounded by connective tissue fibers and penetrated by a network of capillaries. There are four major cell types. The most abundant beta cells (50-80%) secrete INSULIN. Alpha cells (5-20%) secrete GLUCAGON. PP cells (10-35%) secrete PANCREATIC POLYPEPTIDE. Delta cells (~5%) secrete SOMATOSTATIN.

Tumors or cancer in the JEJUNUM region of the small intestine (INTESTINE, SMALL).

The middle portion of the SMALL INTESTINE, between DUODENUM and ILEUM. It represents about 2/5 of the remaining portion of the small intestine below duodenum.

An inherited autosomal recessive syndrome characterized by the disorganized formation of new islets in the PANCREAS and CONGENITAL HYPERINSULINISM. It is due to focal hyperplasia of pancreatic ISLET CELLS budding off from the ductal structures and forming new islets of Langerhans. Mutations in the islet cells involve the potassium channel gene KCNJ11 or the ATP-binding cassette transporter gene ABCC8, both on CHROMOSOME 11.

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.

Anatomic variants in PANCREATIC DUCTS characterized by failure of fusion of the ventral and dorsal endodermal buds. Pancreas divisum results in inadequate or no communication between dorsal and ventral ducts. While most cases are asymptomatic, it may be associated with recurrent PANCREATITIS.

The transference of a pancreas from one human or animal to another.

Devices for simulating the activity of the pancreas. They can be either electromechanical, consisting of a glucose sensor, computer, and insulin pump or bioartificial, consisting of isolated islets of Langerhans in an artificial membrane.

The major component (about 80%) of the PANCREAS composed of acinar functional units of tubular and spherical cells. The acinar cells synthesize and secrete several digestive enzymes such as TRYPSINOGEN; LIPASE; AMYLASE; and RIBONUCLEASE. Secretion from the exocrine pancreas drains into the pancreatic ductal system and empties into the DUODENUM.

Tumors or cancer of the PANCREAS. Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).

A preparation of hog pancreatic enzymes standardized for lipase content.

An inherited syndrome characterized by EXOCRINE PANCREATIC INSUFFICIENCY; hematologic abnormalities (e.g., bone marrow hypoplasia), and skeletal abnormalities (e.g., metaphyseal chondroplasia). GERMLINE MUTATIONS in the SBDS gene are associated with Shwachman-Diamond Syndrome.
