The small intestine absorbs much of the liquid and nutrients from food. The small intestine is made up of the duodenum, jejunum, and ileum.
Resection of the small bowel is performed to correct: blockage of the intestine (intestinal obstruction) due to scar tissue or deformities bleeding, infection, or ulcers due to inflammation of the small intestine (regional ileitis, regional enteritis, or Crohn's disease) injuries cancer precancerous polyps.
While you are deep asleep and pain-free (using general anesthesia), an incision is made in the abdomen.
The diseased part of the small intestine (ileum) is removed. The two healthy ends are either stapled or sewn back together, and the incision is closed. If it is necessary to spare the intestine from its normal digestive work while it heals, a temporary opening (stoma) of the intestine into the abdomen (ileostomy) is made. The ileostomy is later closed and repaired. In some cases, ileostomies are permanent. The ileum absorbs much of its fluid from food. When the large intestine is bypassed by an ileostomy, expect liquid stool (feces). The frequent drainage of liquid stool usually causes the skin around the ileostomy to become inflamed. Careful skin care and a well-fitting ileostomy bag reduce this irritation.
The outcome of your surgery depends on the disease. Most patients stay in the hospital for five to seven days. Complete recovery from surgery may take two months. Eating is restricted during the first few days after surgery.
