Choledochal cyst: an unusual type of cystic dilatation of the cystic duct.

Cystic Dilatation of the Cystic Duct: a Type 6 Biliary Cyst

“…MRCP is highly effective and noninvasive method for evaluating the biliary tree. The anatomical similarity between type 2 choledochal cyst and cystic duct cyst has been reported on before; both Serena Serradel et al [3] and Bode and Aust [5] initially misdiagnosed their cases as type 2 choledochal cysts and Loke et al [8] also mentioned that their case resembled a type 2 choledochal cyst. In such circumstances, one has to depend purely on operative findings and high index of suspicion for the possibility of existence of such a lesion.…”

“…However in some cases [8], as was in our case, the cystic duct junction with the common bile is quite wide and as such necessitates excision of part of common bile duct and thus a Roux-en-Y hepaticojejunostomy may be performed. Use of an isolated conduit of proximal jejunum interposed between common hepatic duct and the remaining part of distal CBD for bridging the gap between the common hepatic duct and duodenum after cyst excision is a reasonably good alternative.…”

Gb, gall bladder, Cd, cystic duct, CHD common hepatic duct [3][4][5][6][7][8][9][10][11][12]. As reported from the previous cases (Table 1), the common symptoms of the cystic duct lesions includes epigastric and/or right upper quadrant pain which is usually exaggerated by a fatty meal [11].…”

“…In our patient, the main feature was pain in the upper abdomen which got aggravated by intake of fatty food. However, an obstruction of the common bile duct may develop because of mass effect by the cyst [5] or due to inflammation resulting from cholangitis [8]. A precise recognition of the extent of the choledochal cyst is crucial before surgery.…”

Type VI choledochal cyst: a rare entity case report and review of literature

“…Serradel S et al and Bode and Aust had misdiagnosed their cases as type 2 choledochal cysts and Loke et al also mentioned that their case resembled a type 2 choledochal cyst. [3][4][5] In such situations, only intraoperative findings can confirm the presence of type VI CDC. The recommended surgical treatment for cystic duct cysts is cholecystectomy with excision of the cyst which leads to cure.…”
