Objective To retrospectively analyze the therapeutic effect of ligaturing pericardial blood vessel combined splenectomy for treating children with gastrointestinal bleeding and hypersplenism secondary to cavernous transformation of portal vein (CTPV).Methods Retrospectively analyzed 30 cases of children with CTPV admitted by Beijing Children's Hospital in General Surgery Department from Jan.2005 to Dec.2012,and evaluated the clinical efficacy of ligaturing pericardial blood vessel combined splenectomy for treating children with gastrointestinal bleeding and hypersplenism secondary to CTPV.Results All of 30 cases admitted operation without serious complication.All children admitted follow-up from 6 to 60 months.Seven cases of 22 patients with gastrointestinal bleeding relapsed bleeding post operation and were cured by conservative treatment.Four cases of 7 relapsing bleeding children had NSAID.All cases of 8 children with simple hypersplenism suggested normal results of blood routine post operation,2 children occurred bloody stools who were cured by conservative treatment.None of patients had serious infection correlating with splenectomy.The size of spleen of patients with gastrointestinal bleeding is larger than patients with simple hypersplenism.Conclusions (1) Ligaturing pericardial blood vessel combined splenectomy is a good choice for children with gastrointestinal bleeding and hypersplenism secondary to CTPV.(2) NSAID may increase the recurrence rate of gastrointestinal bleeding post operation.(3) There may be a negative correlation between the size of spleen and the risk of gastrointestinal bleeding for children with CTPV.
