Giris ve Amaç: Endoskopik retrograd kolanjiografide, bazen çok deneyimli ellerde dahi, hizli ve güvenli bilier kanülasyon, terapötik islem uygulamalari bir problem haline gelebilir. V-sistem degistirilmis bir duodenoskop tipi olup islemi kolaylastirmak ve gelistirmek, endoskopik retrograd kolanjiografi süresini kisaltmak üzere üretilmistir. Bu çalismani n amaci V-sistemin avantajlarini degerlendirmek ve konvansiyonel duodenoskop ile karsilastirmaktir. Gereç ve Yöntem: Ocak/2011 boyunca endoskopik retrograd kolanjiografi için basvuran tüm hastalar bu çalisma için degerlendirildi. V- sistem veya konvansiyonel duodenoskop randomize olarak seçildi. ?slem ile ilgili tüm parametreler kronometre kullanilarak kaydedildi. Bulgular: Çalisamaya 63 hasta dahil edildi, bunlarin 36?si V-sistem grubunda, 27?si ise konvansiyonel duodenoskopi grubunda idi. Gruplarda en sik tani kolelitiazis olup en sik islem ise bilier stent yerlestirilmesi idi. Hem total islem süresi hem de soroskopi süresi V-sistem grubunda belirgin kisa idi. Kilavuz tel kaybi ve kilavuz tele yeniden pozisyon verme ihtiyaci V-sistem grubunda açik olarak daha az idi. Sonuç: V-sistem kilavuz tel kontrolünde ve islem süresinde avantajlar göstermektedir, bu durum endoskopik retrograd kolanjiografi islemlerini uygulamada ikna edici faydalar saglamaktadir.
Background and Aims: Fast and reliable biliary cannulation and therapeutic attempts can be problematic in endoscopic retrograde cholangiography, even in experienced hands. The V-system is a modified duodenoscope design, and was developed in order to simplify and improve the procedure and shorten the length of endoscopic retrograde cholangiography. The aim of this study was to evaluate the V-system advantages and compare the V-system with conventional duodenoscope. Materials and Methods: All patients admitted for biliary endoscopic retrograde cholangiography throughout January 2011 were assessed for the study. Patients were assigned to the V-system or conventional duodenoscope groups randomly. All parameters about the procedure were recorded by a chronometer. Results: Sixty-three patients were included, with 36 in the V-system group and 27 in the conventional duodenoscopy group. The most common diagnosis in the groups was cholelithiasis, and the most common attempt was implantation of biliary stent. Both total procedure time and fluoroscopy time were significantly shorter in the V-system group than conventional duodenoscope group. Loss of guide wire and necessity of guide wire repositioning occurred clearly less often in the V-system group. Conclusions: The V-system has shown some advantages in guide-wire control and procedure length, and provides convincing benefits in the performance of endoscopic retrograde cholangiography procedures.
