Endoscopic variceal ligation combined with sclerotherapy for management of gastroesophageal variceal bleeding in pediatric patients
Abstract Background Portal hypertension (PH) frequently gives rise to severe and life-threatening complications, including hemorrhage accompanied by the rupture of esophageal and gastric varices. In contrast to the widely studied guidelines for the management of PH in adults, there remains controversial about the optimal endoscopic management of variceal bleeding in children for secondary prophylaxis. The study aims to determine the efficacy and safety of endoscopic variceal ligation (EVL) and sclerotherapy (EST) to control bleeding in children in our clinical center. Methods The retrospective study included 21 children with gastroesophageal variceal bleeding who were treated by endoscopic variceal ligation or sclerotherapy at Xinhua Hospital, Shanghai Jiaotong University School of Medicine between January 2007 and July 2020. The treatment outcome involving short-term hemostatic rate and long-term rebleeding rate were investigated. Adverse events related to the procedures, such as esophageal ulcer, esophageal stricture, abnormal embolization, pneumonia and perforation were also observed. Results The 21 pediatric patients who were diagnosed as moderate to severe esophageal varices concurrent with gastric varices experienced EVL or EST successfully. Hemostasis was achieved in 45 of 47 (95.7%) episodes of upper gastrointestinal bleeding. The mean volume of each single aliquot of cyanoacrylate injected was 0.3 ± 0.1 mL (range: 0.1–0.5 mL). Twenty-four patients (75%) reach varices eradication in the EVL group with a median number of procedures before eradication of 2 (1–4) and a median time to eradication of 3.40 months (1.10-13.33). Eleven patients (52.4%) developed rebleeding events, with the mean duration of hemostasis being 11.1 ± 11.6 mo (range: 1.0-39.2 mo). No treatment-related complications, for example, distal embolism, were noted with the exception of abdominal pain in one patient (4.8%). Conclusions Endoscopic variceal sclerotherapy or in combination with EVL turns out to be an effective and safe approach to treat variceal hemorrhage in children for secondary prophylaxis.
