Intestinal fistulas caused by small bowel resection require symptomatic treatment such as drain flushing, anti-infection, parenteral nutritional support, and intestinal anastomosis to correct the fistula.
For relatively small intestinal fistulas, drainage and flushing can be performed. In enterocutaneous fistulae, a double catheter can be placed first for drainage, one drainage tube is injected with saline for continuous flushing, and one drainage tube is used to drain the flushing fluid. Patients also need parenteral nutritional support, anti-infective treatment such as the application of cefuroxime, etc., to maintain the electrolyte balance of the body, protein supplementation.
For larger intestinal fistulas, on the basis of nutritional support and anti-infection, intestinal anastomosis is needed, i.e., surgical correction of the fistula site and removal of intestinal fluids and feces flowing into the abdominal cavity from the fistula.
