A bowel resection or enterectomy (enter-+ -ectomy) is a surgical procedure in which a part of an intestine (bowel) is removed, from either the small intestine or large intestine. Often the word enterectomy is reserved for the sense of small bowel resection, in distinction from colectomy , which covers the sense of large bowel resection.
Jejunoileal bypass (JIB) was a surgical weight-loss procedure performed for the relief of morbid obesity from the 1950s through the 1970s in which all but 30 cm (12 in) to 45 cm (18 in) of the small bowel were detached and set to the side.
Short bowel syndrome in adults and children is most commonly caused by surgery (intestinal resection). [4] In those who undergo intestinal resection, approximately 15% eventually develop small bowel syndrome (75% of those due to 1 large resection and 25% due to multiple separate intestinal resections). [4] This surgery may be done for:
Intestine transplantation dates back to 1959, when a team of surgeons at the University of Minnesota led by Richard C. Lillehei reported successful transplantation of the small intestine in dogs. Five years later in 1964, Ralph Deterling in Boston attempted the first human intestinal transplant, albeit unsuccessfully.
Small intestinal bacterial overgrowth (SIBO), also termed bacterial overgrowth, or small bowel bacterial overgrowth syndrome (SBBOS), is a disorder of excessive bacterial growth in the small intestine. Unlike the colon (or large bowel), which is rich with bacteria, the small bowel usually has fewer than 100,000 organisms per millilitre. [1]
A jejunostomy may be formed following bowel resection in cases where there is a need to bypass the distal small bowel and/or colon due to a bowel leak or perforation. Depending on the length of jejunum resected or bypassed the patient may have resultant short bowel syndrome and require parenteral nutrition. [2]
Short bowel syndrome (SBS) is the condition in which a patient cannot absorb adequate nutrients because a portion of the small intestine is damaged or absent. SBS commonly affects pediatric patients who have undergone surgery, such as premature infants with necrotizing enterocolitis and infants with gastrointestinal defects such as gastroschisis.
The small intestine or small bowel is an organ in the gastrointestinal tract where most of the absorption of nutrients from food takes place. It lies between the stomach and large intestine , and receives bile and pancreatic juice through the pancreatic duct to aid in digestion .
