“…Poor visualization of the cystic duct during surgery may cause accidental bile duct injury. Although the overall incidence of bile duct injury after laparoscopic cholecystectomy is usually lower than 1%, they often emerge in the form of serious complications (2,9,(22)(23)(24)(25). For example, aberrant right posterior duct draining into the common hepatic or cystic duct or draining of the cystic duct into the right hepatic duct (Fig.…”

“…The first variation is represented by the cystic duct joining the right hepatic duct, with an estimated incidence ranging from 0.6 to 2.3% in the general population (Berci, 1992;Kwon et al, 1997). According to some authors, this variation presents an intrinsic surgical risk to a cholecystectomy, as the right hepatic duct may be confused with the cystic duct and so cut and ligated, producing a potentially dangerous outcome (Lahma et al).…”

Anatomic Variations of Extrahepatic Bile Ducts and Evaluation of the Length of Ducts Composing the Cystohepatic Triangle

SUMMARY:It is of paramount importance for surgeons to have a thorough knowledge of the normal anatomy of the extrahepatic bile ducts and its variations due to the high frequency with which they perform in this anatomic site. The cystohepatic triangle, or Calot's Triangle, is bound by the cystic duct, common hepatic duct, and the hepatic border; therefore, its surface area depends on the conformation of these ducts and is closely linked to surgical procedures performed in this region. It has been reported that the length and the position of these ducts may be related to the formation of bile duct stones, Mirizzi's syndrome, and bile duct cancer. Thus, the present work aims to analyze the configuration of the extrahepatic biliary tree and its possible variations, as well as measure the components that make up the cystohepatic triangle. For this task 41 samples from fixated human cadavers were analyzed, with 25 consisting of anatomic parts (liver and biliary tree) and 16 in situ samples. The extrahepatic biliary trees were dissected in order to measure the length of the common hepatic and cystic ducts with a digital caliper, and all anatomic variations were registered. The length of the common hepatic duct varied between 4.18 mm and 50.64 mm, with an average of 21.76 ± 9.51 mm. The length of the cystic duct varied between 7.28 and 38.88 mm, with an average of 19.11 ± 6.77 mm. Anatomic variations were found in 3 samples (7.3%): in one of them the cystic duct connected to the left hepatic duct; in another, the cystic duct connected to the right hepatic duct; in the third, there was a triple confluence of hepatic ducts (two right ducts and one left duct). The results are a contribution to the clinical and surgical anatomy of this region.

“…CTVEGB can clearly show the size, configuration, location, surface and base of gallbladder polyps in accordance with color ultrasound, [1][2][3][4][5][6][7] , is capable of detecting biliary calculus, tumor, anomaly and dilatation of the biliary tract and protruding lesions with a bigger size. However, limited by the concentration of contrast medium, small polypous lesions are easily obscured and thus escaping detection by OCCT.…”

“…Axial CT data could be reconstructed into two-dimensional multi-planar or three-dimensional (3D) volume-rendered images using workstations and imagerendering software [1] . This CT technology combined with the administration of IV cholangiographic contrast agents could produce diagnostic images of the biliary tract [2][3][4][5][6][7]9,10,14] , and has been used for diagnosis of obstructive biliary disease, choledochocele, choledocholithiasis and aberrance bile ducts. The main limitation of this technique is that the rate of allergic reactions and renal or hepatic toxicity (or both) are relatively high due to by these contrast agents.…”

“…Since Klein et al [1] in 1993 reported the computed tomographic cholangiography using spiral scanning and 3D image processing, many lesions of the biliary tract have been studied [2][3][4][5][6][7][8][9][10][11][12][13][14] . In 1994 CT virtual endoscopy (CTVE) was introduced, its application in obtaining organ images has been described extensively [15][16][17][18][19][20][21][22][23][24][25][26][27][28] .…”

AIM:CT virtual endoscopy has been used in the study of various organs of body including the biliary tract, however, CT virtual endoseopy in diagnosis of gallbladder polyps has not yet been reported. This study was to evaluate the diagnostic value of CT virtual endoscopy in polyps of the gallbladder. METHODS:Thirty-two cases of gallbladder polyps were examined by CT virtual endoscopy, ultrasound, CT scan with oral biliary contrast separately and confirmed by operation and pathology. CT biliary cystoscopic findings were analyzed and compared with those of ultrasound and CT scan with oral biliary contrast, and evaluated in comparison with operative and pathologic findings in all cases. RESULTS:The detection rate of gallbladder polyps was 93.8%(90/96), 96.9%(93/96) and 79.2%(76/96) for CT cystoscopy, ultrasound and CT scan with oral contrast, respectively. CT biliary cystoscopy corresponded well with ultrasound as well as pathology in demonstrating the location, size and configuration of polyps. CT endoscopy was superior to ultrasound in viewing the polyps in a more precise way, 3 dimensionally from any angle in space, and showing the surface in details. CT biliary cystoscopy was also superior to CT scan with oral biliary contrast in terms of observation of the base of polyps for the presence of a pedicle, detection rates as well as image quality. The smallest polyp detected by CT biliary cystoscopy was measured 1.5 mm×2.2 mm×2.5 mm. CONCLUSION:CT biliary cystoscopy is a non-invasive and accurate technique for diagnosis and management of gallbladder polyps.
