Background
: Choledochal cysts are seen commonly in Asian populations, but rarely in Western populations. The pathogenesis of these premalignant lesions is not fully understood yet and the risk of malignant transformation increases with age. The overall malignancy risk is 10%–15% in East Asian countries. In this study, we aimed to present our surgical experience as a hepatobiliary center to the literature.
Methods
: We retrospectively analyzed the data from the medical records of 70 patients operated for choledochal cyst between 2008–2019.
Results
: Sixty-two of the 70 (89%) patients were female and 8 (11%) were male, the mean age was 45.89 ± 15.32 years. Overall, 44 (63%) patients had type I (a+b+c), 20 (28%) type V (Caroli), 2 (3%) type II, 2 (3%) type III and 2 (3%) type IVb cysts. The most common operation was cyst excision combined with hepaticojejunostomy (n: 26, 37%). The median diameter of the resected cysts was 3 cm (min- max: 1–11 cm). Malignancy was observed only in three (4%) patients with type III, type Ib, and type V cyts, who were 19, 38, and 72 years old, respectively. Mortality was not observed, morbidity was determined totally in 30 (43%) cases during early and late postoperative periods.
Conclusion
: Type of surgery in choledochal cysts differs according to the type of the cyst. Malignancy was observed at a rate of 4% in all age groups. Although the frequency of malignancy varies, the main treatment of choice should be surgery because malignancy can be seen at a young age.
