Abstract

Aim: Endoscopic sclerotherapy and porto-systemic shunt operations are performed for the prevention of variceal hemorrhage due to extrahepatic portal vein thrombosis (EHPVT). After introduction of mesenterico-left portal bypass procedure (MLPB), the question whether prophy-lactic measures should be used for EHPVT or definitive treatment (MLPB) should be performed became evident. We herein present our experience with MLPB in children with EHPVT. Method: Eight patients treated f or EHPVT (4 boys, 4 girls) were evaluated. While seven patients presented with recurrent variceal hemorrhage, one had only splenomegaly. All patients underwent Doppler US examination, needle liver biopsy and upper GI endoscopy. Seven patients treated with endoscopic sclerotherapy rebled despite repeated sclerotherapies thus underwent MLPB operation. Results: Seven patients presented with variceal hemor-rhage and hypersplenizm. One patient presented with splenomegaly only. In 6 patients among the 7 a MLPB pro-cedure was performed, while one patient died from variceal hemorrhage. Left portal veins were patent in four patients and MLPB procedure was performed. Left portal veins of the remaining two patients were found to be obliterated therefore meso-caval shunt was performed. Upper GI bleeding occurred in the early postoperative period in one patiet wiith MLPB procedure due to a prepyloric ulcer that was successfully treated by endoscopic scle-rotherapy. None of patients with MLPB procedure experienced variceal rebleeding and control endoscopies showed reduction in esophageal varices. Conclusion: Endoscopic sclerotherapy and porto-systemic shunt procedures are intended for prophylaxis of the variceal bleeding due to EHPVT. MLPB procedure is the curative definitive treatment for the children with EHPVT.

Özet

Amaç: Portal ven trombozuna bağlı özofagus varis kanamalarının önlenmesinde yaygın olarak endoskopik skleroterapi veya portosistemik şant tedavileri yeğlenmektedir. Mezenterikosol portal bypass (MSPB) ameliyatının tanımlanması ile "karaciğer dışı portal hipertansiyonlu olgularda varis kanamasının önlenmesi mi yoksa portal ven trombozunun tedavisi mi seçilmelidir?" sorusu gündeme gelmektedir. Çalışmada karaciğer dışı portal hipertansiyonlu (KDPT) olgularda uyguladığımız tedavilerin sonuçlarını sunmak amaçlanmıştır. Yöntem: KDPT nedeni ile izlediğimiz 8 hasta (4 kız, 4 erkek) değerlendirildi. Hastaların 7'sinde tekrarlayan özofagus varis kanaması, bir tanesinde yalnız dalak büyümesi saptandı. Tüm hastalara portal sistem Doppler ultrasonografı (USG), karaciğer örneklemesi ve üst gastrointestinal sistem (GIS) endoskopisi, 7 hastaya endoskopik skleroterapi yapıldı. Bu hastalar kontrol edilemeyen özofagus varis kanama atakları nedeniyle MSPB yapılmak üzere ameliyata alındı. Bulgular: KDPT U 8 olgunun 7'sinde endoskopik skleroterapiye karşın varis kanaması ve hipersplenizm, 1 olguda ise yalnız dalak büyümesi vardı ve izleme alındı. 7 olgunun 6'sı tedaviye karşın varis kanaması ve hipersplenizm nedeni ile ameliyat edilirken,1 olgu kontrol altına alınamayan varis kanaması nedeniyle öldü. Ameliyat edilen 4 olguda sol portal ven açık bulunarak MSPB, 2 olguda sol portal ven tıkalı bulunarak porto-sistemik şant yapıldı. Ameliyat sonrası erken dönemde MSPB yapılan hastaların birinde mide ülserine bağlı üst GİS kanaması oldu, endoskopik tedaviye yanıt verdi. MSPB yapılan hastaların hiçbirinde varis kanaması tekrarlamadı ve endoskopik kontrollerinde varislerin gerilediği görüldü. Sonuç: KDPT U olgularda uygulanan endoskopik skleroterapi veya porto-sistemik şant yöntemleri tedavi edici olmaktan çok özofagus varis kanamalarını önlemeye yöneliktir. MSBP ameliyatı ise erken dönem sonuçları ile KDPT yi tedavi edici bir yöntem olarak seçilmelidir
