A form of intestinal obstruction caused by the PROLAPSE of a part of the intestine into the adjoining intestinal lumen. There are four types: colic, involving segments of the LARGE INTESTINE; enteric, involving only the SMALL INTESTINE; ileocecal, in which the ILEOCECAL VALVE prolapses into the CECUM, drawing the ILEUM along with it; and ileocolic, in which the ileum prolapses through the ileocecal valve into the COLON.

Pathological development in the ILEUM including the ILEOCECAL VALVE.

The valve, at the junction of the CECUM with the COLON, that guards the opening where the ILEUM enters the LARGE INTESTINE.

Pathological development in the JEJUNUM region of the SMALL INTESTINE.

Pathological developments in the CECUM.

Vaccines or candidate vaccines used to prevent infection with ROTAVIRUS.

A solution or compound that is introduced into the RECTUM with the purpose of cleansing the COLON or for diagnostic procedures.

Pathological processes in the COLON region of the large intestine (INTESTINE, LARGE).

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

A benign tumor composed of fat cells (ADIPOCYTES). It can be surrounded by a thin layer of connective tissue (encapsulated), or diffuse without the capsule.

Radiographic examination of the process of defecation after the instillation of a CONTRAST MEDIA into the rectum.

A worm-like blind tube extension from the CECUM.

Any impairment, arrest, or reversal of the normal flow of INTESTINAL CONTENTS toward the ANAL CANAL.

Infection with any of the rotaviruses. Specific infections include human infantile diarrhea, neonatal calf diarrhea, and epidemic diarrhea of infant mice.

Sensation of discomfort, distress, or agony in the abdominal region.

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

Herniation of the RECTUM into the VAGINA.

Tumors or cancer of the CECUM.

A congenital abnormality characterized by the outpouching or sac formation in the ILEUM. It is a remnant of the embryonic YOLK SAC in which the VITELLINE DUCT failed to close.

Radiography using air, oxygen, or some other gas as a contrast medium.

Surgery performed on the digestive system or its parts.

The act of blowing a powder, vapor, or gas into any body cavity for experimental, diagnostic, or therapeutic purposes.

A clinical syndrome with acute abdominal pain that is severe, localized, and rapid in onset. Acute abdomen may be caused by a variety of disorders, injuries, or diseases.

Radiographic visualization of the body between the thorax and the pelvis, i.e., within the peritoneal cavity.

A compound used as an x-ray contrast medium that occurs in nature as the mineral barite. It is also used in various manufacturing applications and mixed into heavy concrete to serve as a radiation shield.

Live vaccines prepared from microorganisms which have undergone physical adaptation (e.g., by radiation or temperature conditioning) or serial passage in laboratory animal hosts or infected tissue/cell cultures, in order to produce avirulent mutant strains capable of inducing protective immunity.
