自发性细菌性腹膜炎(SBP)是肝硬变患者常见和严重的并发症,发生率约占住院病例的15%(均为伴有腹水者),与并发症有关的病死率占50%以上。理论上认为SBP很容易在首次治愈后再发,但尚未证实。本文作者通过对75例曾发生过一次SBP患者的研究,以明确SBP是否呈反复发作的过程,并试图找出可能提示复发的线索。诊断标准:(1)腹痛和/或发热;(2)腹水多形核白细胞计数>500/mm~3; (3) Spontaneous bacterial peritonitis (SBP) is a common and serious complication of cirrhosis, accounting for about 15% of hospitalized cases (all with ascites), with a complication-related mortality rate of more than 50%. In theory, SBP is easy to relapse after the first cure, but it has not been confirmed yet. The authors of this study examined 75 patients with SBP who had an episode of SBP to determine whether SBP was recurrent and attempted to identify clues that might prompt recurrence. Diagnostic criteria: (1) abdominal pain and / or fever; (2) ascites polymorphonuclear leukocyte count> 500 / mm ~ 3; (3)
