简要总结

This study is non-inferiority trial design. This study aimed to investigate the effect of prophylactic oral antibiotics on preventing cholangitis in biliary atresia (BA) patients after Kasai portoenterostomy (KP) by comparing the cholangitis rate in BA patients who received prophylactic oral antibiotics and those who did not. The patients were followed up for 2 years after KP.

详细描述

Biliary atresia (BA) is a devastating inflammatory obstructive neonatal disease affecting intrahepatic and extrahepatic bile ducts. Kasai portoenterostomy (KP) is the mainstay of treatment for BA. Cholangitis is a common complication after KP, with an overall incidence of 22-93%, and an incidence of 30-70% within 6 months after KP. The mechanism of cholangitis may be intestinal bacteria ascending into the intrahepatic biliary system or bacterial colonization, etc. Common causative organisms include Klebsiella, Escherichia coli, Pseudomonas aeruginosa, Enterobacter cloacae, Acinetobacter baumannii, Streptococcus, and Salmonella typhi. There is some controversy about prophylactic antibiotics after KP, and the type, dosage and course of antibiotics in medical institutions around the world vary greatly. After years of improvement, although the postoperative management and short-term prognosis of BA have improved, the overall incidence of cholangitis has not changed much. High-quality evidence for antibiotic prophylaxis after KP remains lacking. It still remains unknown that whether long-term prophylactic oral antibiotics could benefit the patients. Long-term use of antibiotics may not only increase the burden of liver dysfunction in patients, but also lead to antibiotic resistance, intestinal flora disturbance, and increase the risk of allergies and autoimmune diseases. It is of great significance to use evidence-based medicine to find a relatively reasonable cholangitis prevention program.

This study is non-inferiority trial design. This study aimed to investigate the effect of prophylactic oral antibiotics on preventing cholangitis by comparing the cholangitis rate in BA patients who received prophylactic oral antibiotics after KP and those who did not. Patients diagnosed with type III BA and receiving KP at Children's Hospital of Fudan University will be assigned to 2 groups. Both groups received the same basic treatment, then the patients in the antibiotics group received prophylactic oral antibiotics until the 6th month after KP, while the non-antibiotics group no longer used prophylactic antibiotics until cholangitis occurred. The cholangitis rate within 6 months after KP were measured to evaluate the preventive effect of prophylactic oral antibiotics on cholangitis. The patients were followed up for 2 years after KP.

排除标准

  • Patients with cholestasis of non-BA disease;
  • Patients who have undergone KP at other institutions;
  • Patients whose pathohistological diagnosis is in doubt;
  • Patients who undergo liver transplantation immediately after KP;
  • Patients with other liver diseases or severe complications (e.g., severe pulmonary hypertension, renal failure, intracranial hemorrhage, etc.) requiring surgical intervention or other medical therapy;
  • Patients with severe cardiac, renal, or central nerve system malformations (e.g., tetralogy of Fallot, transposition of the great arteries, cerebral dysplasia, etc.) and have poor prognosis;
  • Patients judged by the researchers that they can not comply with the study requirements.

结局指标

主要结局

The occurrence of cholangitis (confirmed or suspected) within 6 months after KP

时间窗: 6 months after KP

Definition of cholangitis: A. Clinical elements 1. Fever and/or shivering; 2. Stool color change; 3. New/increasing jaundice; 4. Abdominal discomfort: vomiting, poor, feeding, irritability. B. Laboratory and imaging elements 1. Inflammatory response (WBC and/or CRP and/or PCT); 2. Increased/increasing transaminases; 3. Increased/increasing GGT and/or bilirubin; 4. Bile lakes. Suspected cholangitis: one item in A + one item in B. Confirmed cholangitis: two items in A + two items in B or "suspected cholangitis" + positive blood culture. The diagnosis of cholangitis requires the exclusion of definite infections of other systems.
