Background: The cystic duct tube (C-tube) was used to reduce bile leakage (BL) incidence after hepatectomy. Nevertheless, delayed BL is sometimes experienced even using C-tube. This study investigates the impact of C-tube use on the onset time of post-hepatectomy BL. Methods: Data from 455 consecutive patients who underwent hepatectomy without biliary reconstruction between November 2007 and July 2020 were analyzed retrospectively. A C-tube was used for intraoperative biliary injury or in consideration of BL risk. BL was divided into two groups according to the postoperative onset time: early onset and late onset. To assess the association between C-tube use and BL, propensity score matching in a 1:1 ratio was performed to match BL risk factors between the C-tube and no-C-tube groups. Results: BL occurred in 30 (6.6%) of the 455 included patients. C-tubes were used in 51 patients (11.2%) with open hepatectomy, high-risk hepatectomy, massive blood loss, long operation time, or prophylactic drain placement. After propensity score matching, BL occurred in 17 of 102 patients (16.7%). Early-onset BL occurred significantly less frequently in the C-tube group than in the no-C-tube group (3.9% vs. 15.7%, p = 0.046); however, late-onset BL was more common in the C-tube group (9.8% vs. 3.9%, p = 0.24). Six of seven patients (85.7%) with BL with C-tube use developed BL after C-tube removal. Conclusion: C-tube drainage may reduce early-onset BL in cases having risk factors for BL. Conversely, since late-onset BL often occurs after C-tube removal, attention should be paid to those cases.
