Small bowel resection usually requires general anesthesia, and after resection of the corresponding intestinal collaterals through an abdominal opening, it is sterilized, anastomosed, and sutured.
Small bowel resection can be performed using any incision in the abdomen. The more commonly used incision is the rectus abdominis muscle incision. The selected segment of intestine to be resected is lifted up, the blood-supplying vessels are cut off with vascular forceps, ligated or sutured with non-absorbable threads, followed by separation of the mesentery, and the mesentery is separated properly, so that the intestinal tubes to be resected do not contain a lot of content.
The area where the bowel is to be cut is then padded with gauze and isolated from the surrounding tissue to minimize contamination. The intestinal tube is also cut along the toothed vascular forceps and the resected bowel loops are removed from the operating table along with the mesentery. The mucosa of the severed end of the preserved small bowel is then sterilized with iodine vapour and finally anastomosed and sutured.
It is recommended that patients who are about to undergo small bowel resection should not be overly anxious, relax, and actively complete the relevant examinations and cooperate with the doctor for treatment.
