| intermesenteric arterial anastomosis | The series of arterial arches formed in the mesentery by anastomoses between adjacent jejunal and ileal arteries and from which vasa recta arise. The arterial arcades of the ileum are shorter and more complex than those of the jejunum. See: arterial arches of ileum, arterial arches of jejunum. Synonym: intermesenteric arterial anastomosis, Riolan's arc, Riolan's arcades. (05 Mar 2000) |

| internal mammary-coronary artery anastomosis | Direct myocardial revascularization in which the internal mammary artery is anastomosed to the right coronary artery, circumflex artery, or anterior descending coronary artery. The internal mammary artery is the most frequent choice, especially for a single graft, for coronary artery bypass surgery. (12 Dec 1998) |
| isoperistaltic anastomosis | An anastomosis allowing flow of contents in the same and normal direction. (05 Mar 2000) |
| termino-terminal anastomosis | An operation by which the central end of an artery is connected with the peripheral end of the corresponding vein, and the peripheral end of the artery with the central end of the vein. (05 Mar 2000) |
| elliptical anastomosis | A modification of direct anastomosis whereby one or both tubular structures are spatulated beforehand, thus creating an ellipse of greater cross-sectional as well as circumferential dimension than would be possible with a bevelled or circular anastomosis. (05 Mar 2000) |
| transureteroureteral anastomosis | Anastomosis of the transsected end of one ureter into the intact contralateral ureter, by direct or elliptical end-to-side technique. See: ureteroureterostomy. Synonym: transureteroureteral anastomosis. Acronym: TUU (05 Mar 2000) |
| Jacobson's anastomosis | A portion of the tympanic plexus. (05 Mar 2000) |
| uretero-ileal anastomosis | Anastomosis between the ureter and an isolated segment of ileum. See: Bricker operation. (05 Mar 2000) |
| ureterosigmoid anastomosis | Anastomosis between the ureter and a segment of the sigmoid colon. (05 Mar 2000) |
| ureterotubal anastomosis | Procedure for anastomosis between the ureter and the fallopian tube. (05 Mar 2000) |
| ureteroureteral anastomosis | Anastomosis from one part of a ureter to another part of the same ureter. (05 Mar 2000) |
| anterior intestinal portal | Anterior intestinal portal; the opening of the foregut into the midgut. See: epigastric fossa. Synonym: anterior intestinal portal. (05 Mar 2000) |
| gas, intestinal | The complaint referred to as intestinal gas is a common one and the discomfort can be quite significant. Everyone has gas and eliminates it by burping or passing it through the rectum. In many instances people think they have too much gas when in reality they have normal amounts. most people produce 1 to 3 pints of intestinal gas in 24 hours and pass gas an average of 14 times a day. It is made up primarily of odourless vapors such as carbon dioxide, oxygen, nitrogen, hydrogen, and in some families, methane. The unpleasant odour is due to bacteria in the large intestine that release small amounts of gases containing sulfur. (12 Dec 1998) |
| vasoactive intestinal contractor | Mouse homologue of endothelin 2. (18 Nov 1997) |
| vasoactive intestinal peptide | <gastroenterology, protein> Peptide of 28 amino acids, originally isolated from porcine intestine, but later found in the central nervous system where it acts as a neuropeptide and is released by specific interneurons. May also affect behaviour of cells of the immune system. Acronym: VIP (05 Jan 1998) |
