Abstract

Background/aims: Peroral cholangioscopy with its limitations led to further research regarding development of SpyScope® technology. The aim of this retrospective study was to investigate the efficacy of a new device and the application of this device in our Liver Transplant Center. Methods: Charts of patients who had undergone evaluation with SpyScope® were retrospectively reviewed. Indications included pre-transplant as well as post-transplant evaluation of biliary strictures. If strictures or filling defects were noted by cholangiogram, SpyScope® was performed. Biopsy was obtained under direct visualization if necessary with SpyBite® biopsy forceps. Demographic features, indications for SpyScope® evaluation, results, and histopathological diagnoses were recorded. Results: Ten patients (6 male, 4 female; median age: 55) had undergone SpyScope® procedure between August 2007 and January 2008. Six out of 10 cases were in the pre-transplant work-up period, referred to as Group I, while the remaining four were post-transplant patients, referred to as Group II. In Group I, 4 of 6 cases had undergone the procedure for work-up of primary sclerosing cholangitis prior to orthotopic liver transplantation. In Group II, indications were either strictures noted during the previous endoscopic retrograde cholangiopancreatography (n=2) or common bile duct stones with elevated total bilirubin levels and stones with long segment biliary stricture (n=2). In the patient with anastomotic stricture, the biliary lithiasis was eventually exposed just above the anastomotic stricture, after abundant lavage was applied at that level. All SpyBite® biopsy specimens were reported to be adequate samples for histopathological examination. No malignancy was detected among 4 patients with primary sclerosing cholangitis and patients with elevated CA 19-9. Conclusions: SpyScope® allows direct visualization of biliary strictures and SpyScope®/SpyBite® were found to be technically superior to conventional cholangiogram with better sampling than brushing obtained by endoscopic retrograde cholangiopancreatography. Prospective, multicenter, large volume studies are warranted to identify its sensitivity and specificity.

Özet

Amaç: Peroral kolanjiyoskopinin uygulanmasının sınırlı olması SpyScope teknolojisinin gelişmesine sebep olmuştur. Bu retrospektif çalışmanın amacı SpyScope'un etkinliği ve Transplant Kliniğimizde uygulama alanlarının belirlenmesidir. Yöntem ve Gereç: Hastaların kayıtları retrospektif olarak değerlendirilmiştir. Endikasyonlar nakil öncesi (Grup I) ve nakil sonrası (Grup II) safra yolu darlıklarının değerlendirilmesi şeklindedir. Gerektiğinde SpyBite biyopsi forsepsi ile direk görüş altında biyopsi alınmıştır. Demografik özellikler, SpyScope endikasyonlarının değerlendirilmesi, sonuçlar ve histopatolojik tanılar kayıt edilmiştir. Bulgular: Ağustos-2007 ile Ocak-2008 tarihleri arasında SpyScope uygulanan 10 hasta (6 erkek 4 kadın ortalama yaş 55) değerlendirilmeye alınmıştır. On hastanın 6 sı Grup I de kalanı Grup 2 de idi. Grup I de, 6 hastanın 4 ü ortotopik karaciğer nakli öncesi rutin olarak değerlendirilen primer sklerozan kolanjitli (PSC) hastalardı. Grup II de, endikasyonlar hem önceki endoskopik retrograd kolanjiyopankreatografi sonucuna göre darlık olan hastalar (n=2), hem de total bilirubin seviyesi yüksek olan ana safra kanalı taşları olan hasta ile uzun segment safra yolu darlığı ile birlikte olan safra yolu taşları olan hasta idi (n=2). SpyBite ile alınan tüm biyopsi örnekleri yeterli örnekleme olarak bildirildi. Dört primer sklerozan kolanjit hastasının ve CA19-9 yüksekliği olan hastaların hiçbirinde maligniteye rastlanmadı. Sonuç: SpyScope safra yolu darlıklarını direk görüşle değerlendirir, bu yöntem teknik olarak konvansiyonel kolanjiografiye ve retrograd kolanjiyopankreatografi de fırçalama yöntemi ile alınan biyopsilere göre üstündür. Prospektif, çok merkezli ve daha çok hasta sayısı içeren çalışmalarla sensitivitesi ve spesifitesi hakkında bilgi sahibi olunabilir.
