“…A thin aberrant hepatic duct that drains a segmental or smaller hepatic area may be encountered [17][19] [20]. Surgeons may injure or incorrectly ligate these ducts, resulting in a stula or liver abscess [21]. In our study, we found nine cases of these thin aberrant hepatic ducts (4.4%), including six that drained segment 5 and three that drained segment 6 (Fig S1).…”

BackgroundEvaluation of the cystic duct anatomy prior to cholecystectomy is important, to decrease the risk of bile duct injury. This study aimed to clarify the frequency of cystic duct variations and the relationship between them. MethodsData of 205 patients who underwent cholecystectomy after imaging at Sada Hospital, Japan, were analyzed. The Chi-square test was used to analyze the relationships among variations. ResultsThe lateral and posterior sides of the bile duct were the two most common insertion points (92 patients, 44.9%), and the middle height was the most common insertion height (135 patients, 65.9%). Clinically important variations (spiral courses, parallel courses, low insertions, and right hepatic duct draining) relating to the risk of bile duct injury were observed in 24 patients (11.7%). Regarding the relationship between the insertion sides and heights, we noticed that the posterior insertion frequently existed in low insertions (75.0%, P < 0.001) and did not exist in high insertions. In contrast, the anterior insertion coexisted with high and never low insertions. Spiral courses have two courses: anterior and posterior, and anterior ones were only found in high insertion cases. ConclusionsThe insertion point of the cystic duct and the spiral courses tended to be anterior or lateral superiorly and posterior inferiorly. Clinically signi cant variations in cystic duct insertions are common and surgeons should be cautious about these variations to avoid complications.
