“…Nevertheless, by covering supplementary endoscopic characteristics of the papilla, we needed to consider the limitation of using a non-validated classification. However, suggestions for such classifications were made within several publications [ 10 , 17 ]. While using an interobserver- and intraobserver-validated classification proves useful and relevant in an everyday clinical setting [ 15 , 16 ], adding up to such classification would not provide less generalizable results within a single center prospective cohort.…”

“…Its appearance was classified in either regular anatomy or one of the four anatomical variations. The classification expansion used within the study was based on a former definition of the papillary anatomical variations previously published by Canard et al in 2011 [17]. By adapting the former description of anatomical variants, we obtained an objective and reproducible classification add-on suitable for our study design.…”

Background: Endoscopic retrograde cholangiopancreatography (ERCP) has been one of the most intensely studied endoscopic procedures due to its overall high complication rates when compared to other digestive endoscopy procedures. The safety and outcome of such procedures have been linked to multiple procedure- or patient-related risk factors. The aim of our study is to evaluate whether the morphology of the major duodenal papilla influences the ERCP outcomes and complication rates. Methods: A total of 322 patients with a native papilla have been included in the study over an eight month period. Morphology of the papilla has been classified into normal papilla and four anatomical variations (Type I-IV). All patients have been prospectively monitored over a 15 day period after ERCP. Procedural outcomes and complication rates have been registered. Results: Morphology of the papilla influences both overall complication rates (95%CI, p = 0.0066) and post-ERCP pancreatitis rates (95%CI, p = 0.01001) in univariate analysis. Type IV papillae have proven to be independent risk factors for post-ERCP pancreatitis in multivariate analysis (OR = 12.176, 95%CI, p = 0.005). Type I papillae have been significantly linked to difficult cannulation (AUC = 0.591, 95%CI, p = 0.008); Conclusions: In the monitored cohort morphology of the major duodenal papilla has significantly influenced both ERCP outcomes and post-procedural complication rates.

“…By comparing our study to the above mentioned studies we can estimate a wide variability in the accuracy of different diagnostic modalities especially EUS and MRCP for diagnosing biliary diseases, and this may indicate multiple factors contributing to such difference, including level of expertise in performing EUS, Un availability of specific guidelines for a better patient stratification and a time lapse between different studies, in addition to the sample size as mentioned before. One of the important factor which should be taken in to consideration is a spontaneous passage of gallstones in a period between performing EUS and ERCP, this is supported by a study done by Frossard et al [23], which reported that spontaneous passage of stones occurred at a rate of 20% per a week, especially if a stone very small (<5 mm) [24] .…”

Background: Pancreatobiliarydiseases (PBD) comprises diseases of both biliary system and pancreas and their diagnosis depends on appropriate clinical evaluation and investigations including imaging modalities like transabdominal ultrasound (TAUS), Magnetic resonance cholangiopancreatography (MRCP) and computed tomography (CT); Endoscopic ultrasound(EUS) have been found to be more sensitive than other imaging modality for detecting PBD, and less invasive than endoscopic retrograde cholangiopancreatography (ERCP). Aim of study: To compare the sensitivity and specificity of EUS with other imaging studies like ERCP, TAUS, CT scan, and MRCP/MRI for diagnosing PBD. Patients & Methods: This study conducted in Kurdistan Centre for Gastroenterology and Hepatology (KCGH) from December 2013 through December 2014, after approval of institutional board ethical committee and taking written informed consents from all patients. A total number of 100 patients were enrolled in the study. We calculated the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of EUS, MRCP, and TAUS for PBD (benign & malignant). ERCP was used as a reference standard for comparison. Results: 60% were females and 40% were males; the main presenting symptoms were combined abdominal pain and obstructive jaundice. The sensitivity, specificity, PPV, NPV, and accuracy of EUS for detecting benign biliary diseases like (bile duct stone and its complications) were 96.1%, 65.2%, 86%, 83.3%, and 89%, respectively; and for detecting pancreatobiliary tumors (PBT) were 84.6%, 97.7%, 84.6%, 97.7%, and 96%, respectively. The sensitivity of TAUS, MRCP for diagnosing biliary diseases were 58%, and 60%, respectively; and their sensitivity for detecting PBT were 37.5%, and 50%, respectively. The comparison between CT scan and ERCP was not feasible statistically. Conclusion: EUS has a higher sensitivity in comparison to other imaging modalities in detecting PBD; we can depend on it in selecting patients for therapeutic ERCP, in order to avoid unnecessary ERCP and its complications. The sensitivity and specificity of EUS in KCGH is comparable to other studies elsewhere.

“…After localizing the MDP in the duodenum with the side-viewing endoscope, different instruments and techniques are used to cannulate the common bile duct (CBD) and/or pancreatic duct (PD). A contrast agent is injected to opacify the biliary system and/or the pancreatic duct, allowing radiologic visualization, diagnosis and different therapeutic interventions (Canard, Lennon, Létard, Etienne, & Okolo, 2011). Endoscopic retrograde cholangiopancreatography (ERCP) technique is regarded as a complex and advanced endoscopic procedure because of its need for a variety of instruments and accessories as well as its long learning curve which is needed to develop competency with this technique.…”
