“…Clear visualization of biliary ducts is critical for precise anatomical reconstruction. 12 We placed the 3D printed model inside the black box to simulate the conditions of a clinical examination in which the intrahepatic bile ducts cannot be observed directly, and the overlay display technique was used for viewing the reconstructed images. Using this type of see-through display, the image appears as a reflection in a semitransparent mirror, thus allowing the surgeon to look directly at the surgical field while viewing the AR imagery.…”

“…Three Dimensional Balanced Turbo-Field-Echo (BTFE): While MR Cholangio-Pancreatography (MRCP) can only visualize the bile ducts, 3D balanced turbo-ield-echo (BTFE) sequence clearly depicts the bile ducts and portal veins as well as drip infusion CT cholangiography (DICCT), without contrast media. Similar to DIC-CT, the BTFE MR sequence had high diagnostic accuracy regarding the branching pattern of the intrahepatic bile duct, especially for the supra-/ infra-portal type [11]. 4.…”

What is called "idiopathic biliary duct system dilatation" or better to name it "un-explained biliary dilatation" is mostly following surgical procedures related to upper gastrointestinal and hepato-bilio-pancreatic systems. Having such situation, adaptive physiology of the biliary duct system has to be considered and rational has to be explained. The vast multimodal progress in techniques of investigations that has been applied on studying the hepato-bilio-pancreatic system has been utilized to clear the clinical ambiguity of biliary duct system dilatation for no logic reason but missing the correlation between both fi elds; the technical and the clinical ones. This clinical review is trying to fi ll this gap and introduce a comprehensive discussion of the subject. Mechanical, biochemical and immune causes constitute a wide diversity of etiology related to biliary system dilatation that in some situations is really diffi cult to verify clinically. On the least, even we could not verify the etiology we need to identify that reaching a closed road is different than postulating suspicions that never exist. This review is a trial collecting all subject-related data that might be related to etiology mechanisms and utilize to fi nd a correlation rationale. At some point verifi cation of such correlation is really a far target that might be even impossible clinically with availing technical tools and hope in the future could be achieved.

BackgroundDrip infusion cholangiography with computed tomography (DIC‐CT) is a major preoperative modality used for patients undergoing laparoscopic cholecystectomy (LC).MethodsThis study included 218 patients for whom preoperative DIC‐CT images were obtained prior to undergoing LC. The association between gallbladder (GB) opacification in DIC‐CT and the operative time was assessed.ResultsThe GB opacification on the DIC‐CT images was classified as follows: Grade 0, homogeneous opacification; Grade 1, heterogeneous opacification; Grade 2, only cystic duct can be identified; and Grade 3, no opacification. Images obtained for the 218 patients showed 41 (18.8%) with Grade 0, 91 (41.7%) with Grade 1, 54 (24.8%) with Grade 2, and 32 (14.7%) with Grade 3. The operative time and intraoperative blood loss were significantly longer and larger, respectively, in cases classified as Grade 2 or 3 (GB negative) compared with cases classified as Grade 0 or 1 (GB positive). We created an LC difficulty score based on the following variables that were significant independent predictors of increased operative time: GB negativity in DIC‐CT (P = .002, 2 points), GB wall thickness (P = .002, 2 points), body mass index (P = .015, 1 point), preoperative alkaline phosphatase value (P = .018, 1 point), and preoperative C‐reactive protein value (P = .04, 1 point). The LC difficulty score (Grade A, score 0‐2; Grade B, score 3‐5; and Grade C, score 6‐7) was significantly associated with a prolonged operative time.ConclusionDrip infusion cholangiography with computed tomography is useful for predicting the surgical difficulty of LC.
