Bowel obstruction is a blockage of the small or large intestine which prevents the normal movement of the products of digestion. [11] It may occur due to scar tissue after surgery, twisting of the bowel around itself, hernias, or gastrointestinal tumors. Reduced forward movement of bowel contents results in a build up of pressure within the ...
Strictureplasty (also spelled Stricturoplasty) is a surgical procedure performed to alleviate bowel narrowing due to scar tissue that has built up in the intestinal wall from inflammatory bowel conditions such as Crohn's disease. The scar tissue accumulates as a result of repeated damage and healing, with the scarring causing a stricture (a ...
Adhesion-related twisting and pulling of internal organs may result in complications such as abdominal pain or intestinal obstruction. Small bowel obstruction (SBO) is a significant consequence of post-surgical adhesions. A SBO may be caused when an adhesion pulls or kinks the small intestine and prevents the flow of content through the ...
Goblet cells secrete mucus, which lubricates the passage of food along and protects the intestinal wall from digestive enzymes. In the small intestine, villi are folds of the mucosa that increase the surface area of the intestine. The villi contain a lacteal, a vessel connected to the lymph system that aids in the removal of lipids and tissue ...
A minimal response includes the formation of fibrosis around the prosthesis (much like in scar tissue formation); this response is generated with the best form of biocompatibility. A physical response triggers an acute inflammatory reaction, which involves the formation of giant cells and subsequently granulomas, meaning that the tissue is ...
[3] [4] [5] Overlapping anterior sphincteroplasty is preceded by a bowel preparation and possibly antibiotics. Once the patient is under anesthesia, an incision is made in front of the anus (the anterior perineum). Scar tissue is removed and the mucosa of the anal canal separated from the damaged sphincter.
In medicine, desmoplasia is the growth of fibrous connective tissue. [1] It is also called a desmoplastic reaction to emphasize that it is secondary to an insult. Desmoplasia may occur around a neoplasm, causing dense fibrosis around the tumor, [1] or scar tissue within the abdomen after abdominal surgery. [1]
The upper portion is the abdominal cavity, and it contains the stomach, liver, pancreas, spleen, gallbladder, kidneys, small intestine, and most of the large intestine. The lower portion is the pelvic cavity, and it contains the urinary bladder, the rest of the large intestine (the lower portion), and the internal reproductive organs. [2] [3]
