AIM:To study the endoscopic and radiological characteristics of patients with hepaticojejunostomy(HJ)and propose a practical HJ stricture classif ication.METHODS:In a retrospective observational study,a balloon-assisted enteroscopy(BAE)-endoscopic retrograde cholangiography was performed 44 times in 32 patients with surgically-altered gastrointestinal(GI)anatomy.BAE-endoscopic retrograde cholangio pancreatography(ERCP)was performed 23 times in 18 patients with HJ.The HJ was carefully studied with the endoscope and using cholangiography.RESULTS:The authors observed that the hepaticojejunostomies have characteristics that may allow these to be classif ied based on endoscopic and cholangiographic appearances:the HJ orif ice aspect may appear as small(type A)or large(type B)and the stricture may be short(type 1),long(type 2)and type 3,intrahepatic biliary strictures not associated with anastomotic stenosis.In total,7 patients had type A1,4 patients A2,one patient had B1,one patient had B(large orif ice without stenosis)and one patient had type B3.CONCLUSION:This practical classification allows for an accurate initial assessment of the HJ,thus potentially allowing for adequate therapeutic planning,as the shape,length and complexity of the HJ and biliary tree choice may mandate the type of diagnostic and thera-peutic accessories to be used.Of additional importance,a standardized classif ication may allow for better com-parison of studies of patients undergoing BAE-ERCP in the setting of altered upper GI anatomy.
AIM: To study the endoscopic and radiological characteristics of patients with hepaticojejunostomy (HJ) and propose a practical HJ stricture classification. METHODS: In a retrospective observational study, a balloon-assisted enteroscopy (BAE)-endoscopic retrograde cholangiography was performed 44 times in 32 patients with surgically-altered gastrointestinal (GI) anatomy. BAE-endoscopic retrograde cholangio pancreatography (ERCP) was performed 23 times in 18 patients with HJ. The HJ was carefully studied with the endoscope and using cholangiography. RESULTS: The authors observed that the hepaticojejunostomies have characteristics that may allow these to be classified based on endoscopic and cholangiographic appearances: the HJ orifice aspect may appear as small (type A) or large (type B) and the stricture may be short (type 1), long (type 2) and type 3, intrahepatic biliary strictures not associated with anastomotic stenosis. In total, 7 patients had type A1, 4 patients A2, one patient had B1, one patient had B (large orifice without stenosis) and one patient had type B3. CONCLUSION: This practical classification allows for an accurate initial assessment of the HJ, thus potentially allowing for adequate therapeutic planning, as the shape, length and complexity of the HJ and biliary tree choice may mandate the type of diagnostic and therapeutic accessories to be used. Of additional importance, a standardized classification may allow for better comparison of studies of patients undergoing BAE-ERCP in the setting of altered upper GI anatomy.
