The most direct gold standard for the diagnosis of abdominal tuberculosis is an abdominal tissue biopsy. Routinely take laparoscopy to take the corresponding tissue for pathological biopsy, if the pathological tissue found in the mycobacterium tuberculosis or typical caseous granuloma, it can be confirmed that it is abdominal tuberculosis. Clinical diagnosis of abdominal tuberculosis is relatively difficult because patients with abdominal tuberculosis mainly have abdominal fluid, in which tubercle bacilli are rare and difficult to find, and the proportion of patients with simple abdominal tuberculosis who receive laparoscopic treatment is relatively low. Therefore, most of the patients with abdominal tuberculosis are diagnosed by clinical diagnosis combined with blood tests and tests related to abdominal fluid.
