Serial transverse enteroplasty (STEP) is a surgical procedure used primarily in the treatment of short bowel syndrome (SBS). In STEP, by making cuts in the intestine and creating a zigzag pattern, surgeons lengthen the amount of bowel available to absorb nutrients.
In the small intestine, the larger part of digestion takes place and this is helped by the secretions of bile, pancreatic juice and intestinal juice. The intestinal walls are lined with villi, and their epithelial cells are covered with numerous microvilli to improve the absorption of nutrients by increasing the surface area of the intestine ...
The intestine is also called the bowel or the gut. The lower GI starts at the pyloric sphincter of the stomach and finishes at the anus. The small intestine is subdivided into the duodenum, the jejunum and the ileum. The cecum marks the division between the small and large intestine. The large intestine includes the rectum and anal canal. [2]
Due to the sensitivity of the intestine to ischemic injury, many potential donor intestines are lost to the events following brain death and trauma. Furthermore, irreversible intestinal damage is seen after approximately only 5 hours of cold ischemia in the form of mucosal damage and bacterial translocation outside the gastrointestinal tract.
The small intestine is the site where most of the nutrients from ingested food are absorbed. The inner wall, or mucosa, of the small intestine, is lined with intestinal epithelium, a simple columnar epithelium. Structurally, the mucosa is covered in wrinkles or flaps called circular folds, which are considered permanent features in the mucosa.
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.
