Objective To analyze the clinical characteristic of spontaneous bacterial peritonitis (SBP) in patients with severe viral hepatitis, and explore its clinical classification and significance. Methods A retrospective research of 120 cases of SBP associated with severe viral hepatitis was performed, and main clinical symptoms and physical signs appeared at the early onset were classified and explored. Results Clinical manifestations of SBP in patients with severe viral hepatitis included 5 types, which were conventional type(41.7%, 50/120), symptomless type(15.8%, 19/120), hepatic coma type(13.3%, 16/120), refractory aacites type (17.5%, 21/120), and shock type (11.7%, 14/120). The germieuhure positive rate of SBP with hepatic coma type and shock type were relatively high, and the survival rate of these patients were low. Conclusions Clinical manifestations of SBP in patients with severe viral hepatitis may be atypical, and its classification help to enhancing the understanding and early diagnosis of SBP, and decreasing missed diagnosis. The prognosis of SBP in patients with hepatic coma type and shock type was poor, and then it must be taken high into account more than ever before in the clinical practice.
