Clinical analysis of regional portal hypertension

Objective To investigate the etiology, clinical features, diagnosis and treatment of regional portal hypertension (RPH).Methods The clinical data of 26 patients with RPH treated in Beijing Chaoyang Hospital Affiliated to Capital Medical University between January 2005 and June 2010 were analyzed with retrospective analysis.The first symptom, routine analysis of blood, liver function test, hepatitis B and C markers, tumor markers, abdominal ultrasound, abdominal enhanced CT, endoscopy findings of 26 patients and the results of abdominal CT angiography (CTA) of 16cases were analyzed.Results Pancreatic disease (18 cases) was the leading cause of RPH.The main clinical manifestations of splenomegaly in 26 cases, irregularly abdominal pain in 14 cases, and upper gastrointestinal bleeding in 10 cases.Isolated gastric varices were revealed by endoscopy in 25 cases,complicated with lower esophageal varices in 1 case.4 cases with endoscopic tissue glue injection in gastric variceal bleeding, splenectomy in 4 cases, 2 cases with splenectomy and pericardialdevascularization, 2 cases with splenectomy, pancreatic tail resection and spleno-renal shunt, 3 cases with splenic embolization treatment.Conclusions RPH often accompanied by pancreatic disease,manifested as splenomegaly, hypersplenism, but normal liver function, absence of liver cirrhosis.Isolated gastric varices is the characteristic features of RPH.RPH caused by benign diseases is curable.Splenectomy is more effective than simple endoscopic hemostasis in RPH associated with gastrointestinal bleeding.
