Sclerotherapy versus beta-blockers for primary prophylaxis of oesophageal variceal bleeding in children and adolescents with chronic liver disease or portal vein thrombosis

Abstract

Background: Portal hypertension commonly accompanies advanced liver disease and often gives rise to life-threatening complications, including bleeding (haemorrhage) from oesophageal and gastrointestinal varices. Variceal bleeding commonly occurs in children with chronic liver disease or portal vein obstruction. Prevention is therefore important. Primary prophylaxis of variceal bleeding in adults is the established standard of care because of the results of numerous randomised clinical trials demonstrating the efficacy of non-selective beta-blockers or endoscopic variceal ligation in decreasing the incidence of variceal bleeding. However, sclerotherapy is the only endoscopic prophylactic option currently available in infants weighing less than 10 kg of bodyweight due to the size of the endoscopic ligator.

Objectives: To assess the benefits and harms of sclerotherapy versus any type of beta-blocker for primary prophylaxis of oesophageal variceal bleeding in children and adolescents with chronic liver disease or portal vein thrombosis.

Search methods: We searched The Cochrane Hepato-Biliary Group Controlled Trials Register, CENTRAL, PubMed, Embase Elsevier, LILACS (Bireme), and Science Citation Index Expanded (Web of Science) in February 2019. We scrutinised the reference lists of the retrieved publications and performed a manual search from the main paediatric gastroenterology and hepatology conferences (NASPGHAN and ESPGHAN) abstract books from January 2008 to December 2018. We searched ClinicalTrials.gov, FDA, EMA, and WHO, for ongoing clinical trials. There were no language or document type restrictions.

Selection criteria: We planned to include randomised clinical trials irrespective of blinding, language, or publication status, assessing sclerotherapy versus any type of beta-blocker for primary prophylaxis of oesophageal variceal bleeding in children and adolescents with chronic liver disease or portal vein thrombosis. We planned to include quasi-randomised and other observational studies retrieved with the searches for randomised clinical trials for report of harm.

Data collection and analysis: We planned to collect and summarise data from randomised clinical trials as described in our protocol, using standard Cochrane methodologies.

Main results: We found no randomised clinical trials assessing sclerotherapy versus beta-blockers for primary prophylaxis of oesophageal variceal bleeding in children and adolescents with chronic liver disease or portal vein thrombosis.

Authors' conclusions: Randomised clinical trials assessing the benefits or harms of sclerotherapy versus beta-blockers for primary prophylaxis of oesophageal variceal bleeding in children and adolescents with chronic liver disease or portal vein thrombosis are lacking. Therefore, trials with adequate power and proper design, assessing the benefits and harms of sclerotherapy versus beta-blockers on patient-relevant clinical outcomes such as mortality, failure to control bleeding, and adverse events are needed. Unless such trials are conducted and the results become published, we cannot make any conclusions regarding the benefits or harms of the two interventions.
