A duodenocolic fistula that is complicated by a severe abdominal infection, toxic shock from infection, or is itself caused by a tumor may lead to death in the short term or within a few years depending on the rate of tumor progression, but if repaired or removed in time, the prognosis is good and life expectancy is not usually affected. A duodenocutaneous fistula is a rupture of the intestinal canal in the body that allows material from the intestines to flow out of the intestinal cavity into the abdominal cavity, leading to infection and malnutrition. Usually manifested as abdominal pain, abdominal distension, or even stop defecation, bowel movement and so on. As for how long patients with enterocutaneous fistula can live, it needs to be further analyzed according to the cause of the disease and the patient’s condition, the cause of the disease and their own physical qualities are different, their survival time is also different. If the intestinal fistula caused by trauma and other reasons, through surgical treatment can be cured, the patient can survive for a long time. If the fistula is caused by an intestinal tumor, it depends on the pathological nature of the primary tumor, whether it is sensitive to radiotherapy, and the patient’s own condition to determine how long he can survive, which may be a few months or a few years. If you are suffering from duodenocolic fistula, it is recommended to actively treat it under the guidance of a doctor and to adjust your mindset in order to get a better recovery and live longer.
