Treatment of Upper Gastrointestinal Bleeding by Percutaneous Transsplenic Varices Embolization in Chronic Hepatic Schistosomiasis Japonicum Patients

To evaluate percutaneous transsplenic varices embolization (PTSVE) in the treatment of upper gastrointestinal bleeding (UGIB) in patients with chronic hepatic schistosomiasis japonicum (CHS), 29 CHS patients (20 males and 9 females) complicated with UGIB were selected as the investigation subjects. The patients were treated by PTSVE under the guidance of X-ray fluoroscopy. The success rate of PTSVE and the rate of complications were observed. In addition, the degrees of varices before and after PTSVE were evaluated by abdominal computed tomography (CT). Results showed that 26 CHS patients (89.6%) were successfully treated with PTSVE. Three cases (10.3%) failed, and two experienced intraperitoneal bleeding within 1 week after PTSVE. The abdominal CT showed a significant decrease of the varices stage in coronary (P < 0.001), esophageal (P = 0.006), and paraesophageal (P = 0.013) varices, but slightly increased perisplenic varices within 1 month of the intervention (P = 0.014). PTSVE may be a safe and effective procedure for the treatment of UGIB in CHS patients, particularly suitable for those with a widened hepatic fissure and exposed hepatic portal vein trunk and an enlarged spleen.
