After conservative treatment of an intestinal fistula, successful treatment is indicated when the contents within the intestine do not flow outward. The cause of enterocutaneous fistula is highly related to poorly healed surgical incisions or trauma. Treatment of enterocutaneous fistula in the infection period is generally used anti-inflammatory drugs to fight infection, acid suppression to inhibit the secretion of intestinal fluid to reduce the irritation, nutritional supportive therapy, etc. After a period of time after the change of medication, such as the infection is under control, can be considered to carry out dissections, diseased intestinal tube resection, intestinal anastomosis. During conservative treatment, a small number of patients may have electrolyte disorders and hypovolemic shock due to large amounts of intestinal fluid exudation, therefore, patients with large amounts of exudation of intestinal fistulas should be predicted to lose body fluids for appropriate rehydration. To determine whether the patient’s intestinal fistula is healed, can be based on the digestive tract imaging examination, to see whether the channel with the outside world is closed, no intestinal fluid leakage, which also means that the intestinal fistula has been healed. It is recommended that when an intestinal fistula occurs, timely medical treatment to improve the relevant examination, standardized treatment, so as to avoid delaying the condition of the adverse consequences.
