| retinal perforation | <ophthalmology> Perforations through the whole thickness of the retina including the macula as the result of inflammation, trauma, degeneration, etc. The concept includes retinal breaks, tears, dialyses, and holes. (12 Dec 1998) |
| peptic ulcer perforation | Penetration of a peptic ulcer through the stomach wall. May be free, i.e., at a point where the stomach wall faces a real or potential space,, or confined, i.e., at a point where the stomach wall is defended by contiguous or adjacent structures, such as the pancreas. (12 Dec 1998) |
| perforation | 1. The act of boring or piercing through a part. 2. A hole made through a part or substance. Origin: L. Perforare = to pierce through (18 Nov 1997) |
| intestinal perforation | <surgery> This surgical emergency involves rupture of the wall of the intestine. Intestinal perforation results in severe abdominal pain intensified by movement. Later symptoms include fever and chills. Underlying causes include appendicitis, gastrointestinal cancer and diverticulitis. (10 Jan 1998) |
| oesophageal perforation | <radiology> Usually in neonates, upper oesophagus frequently affected, then NG tube dissects posteriorly, relatively benign in neonates CXR findings: pneumothorax, pneumomediastinum, abnormal distance between NG tube and trachea on lateral view, NG tube does not terminate in stomach, thin irregular tract (with contrast) vs. Large regular tract (tracheo-oesophageal fistula), pleural effusion, patchy infiltrates see: oesophageal trauma (12 Dec 1998) |
| tympanic membrane perforation | An opening in the tympanic membrane usually caused by trauma. There are four general categories: compression injuries (the most common and usually the result of a blow to the ear); instrumentation injuries (the second most common, usually inadvertent, caused often by cotton swabs or bobby-pins); burn-slag injuries (frequently seen in industry, from hot metal from machines or welding); and blast injuries (usually seen during war or as a result of terrorist bombing). In the absence of infection, most traumatic tympanic membrane perforations heal spontaneously. Persistent perforation is usually a manifestation of tubotympanitis, an inflammation of the eustachian tube and tympanic cavity (middle ear). (12 Dec 1998) |
| uterine perforation | Penetration through the uterine wall. (12 Dec 1998) |
| adynamic ileus simulating bowel obstruction | <radiology> Chronic idiopathic intestinal pseudo-obstrction, pelvic surgery, urinary retention, pancreatitis, acute intermittent porphyria, ceroidosis, neonatal adynamic ileus (12 Dec 1998) |
| bowel | A general term that includes the small and large intestine. (27 Sep 1997) |
| bowel bypass | A surgical procedure consisting of the anastomosis of the proximal part of the jejunum to the distal portion of the ileum, so as to bypass the nutrient-absorptive segment of the small intestine, to treat morbid obesity. (12 Dec 1998) |
| bowel bypass syndrome | <syndrome> Fever, chills, malaise, and inflammatory cutaneous papules and pustules on the extremities and upper trunk, sometimes with polyarthralgia, with recurrent symptoms following bowel bypass surgery. (05 Mar 2000) |
| bowel disorders and fibre | High fibre diets help delay the progression of diverticulosis and, at least, reduce the bouts of diverticulitis. In many cases, it helps reduce the symptoms of the Irritable Bowel Syndrome ( IBS ). It is generally accepted that a diet high in fibre is protective, or at least reduces the incidence, of colon polyps and colon cancer. (12 Dec 1998) |
| bowel infections | An infection, viral or bacterial, of the intestines. (27 Sep 1997) |
| bowel movement | Defecation. (05 Mar 2000) |
