The Morphological Aberrations of Cystic Duct and its Clinical Significance: A Gross Anatomical Study
Introduction: The Cystic Duct (CD) serves as a thorough fare for transport of bile to and away from the gallbladder. It is about 2-4 cm in length and 1-5 mm in diameter, and joins the Common Hepatic Duct (CHD) at its right lateral aspect, in the middle third to form the Common Bile Duct (CBD)....

| Summary: | Introduction: The Cystic Duct (CD) serves as a thorough
fare for transport of bile to and away from the gallbladder.
It is about 2-4 cm in length and 1-5 mm in diameter, and
joins the Common Hepatic Duct (CHD) at its right lateral
aspect, in the middle third to form the Common Bile Duct
(CBD). A large number of variations are seen in its anatomy
which is either due to aberrations during its developmental
process or a result of underlying pathology.
Aim: To study the length, diameter, course, site and level
of insertion of the CD. Presence of any other anomaly was
also looked into.
Materials and Methods: This study was undertaken on one
hundred specimens of liver along with entire extra hepatic
biliary apparatus, in the Department of Anatomy, Jawaharlal
Nehru Medical College, Sawangi (Meghe), Wardha, and
Subharti Medical College, between 2008 to 2013. Total 100
cadavers considered for the study. The morphology of CD
was studied with respect to its length, mid length diameter,
course, site and level of insertion and the presence of other
anomalies
Results: In 99 (99%) specimens the CD joined the CHD
and in one (1%) it joined the Right Hepatic Duct (RHD). The
length of the CD was found between 0.2 cm to 6.2 cm. The
mid-length diameter of the CD ranged from 0.2 cm-0.8 cm.
The course of CD was angular in 53 (53%), parallel in 23
(23%), spiral in 24 (24%) specimens. The site of insertion
in 76 (76%) specimens, was right lateral, in 4 (4 %) it was
anterior, in 15 (15%) it was posterior and in 5 (5%) was left
medial. A tubular channel was seen arising from the wall of
the gallbladder and draining into CHD above the opening
of the usual one.
Conclusion: Important variations were found which are
significant from the surgical point of view, especially as
there is a surge in laparoscopic cholecystectomies and
other minimally invasive procedures in the recent era. |
