  1. Bold values indicate significant differences
  2. Data are presented as mean ± standard deviation unless otherwise indicated
  3. ≤ 7-day group: patients with an interval between PTGBD and surgery ≤ 7 days, ≥ 8-day group: patients with an interval between PTGBD and surgery ≥ 8 days, PTGBD: percutaneous transhepatic gallbladder drainage, WBC: white blood cell, CRP: C-reactive protein, ASA: American Society of Anesthesiologists
  4. We also compared the outcomes between patients with an interval between PTGBD and surgery of ≤ 14 days (≤ 14-day group; n = 10) and those with an interval of ≥ 15 days (≥ 15-day group; n = 12) (Table 5). The ≤ 14-day group had significantly less comorbidity than the ≥ 15-day group (p < 0.0426). Further, the CRP before surgery was significantly higher in the ≤ 14-day group than in the ≥ 15-day group (p < 0.0007), and the total hospitalization was significantly shorter (p < 0.0060)
  5. We further compared the outcomes using 3-day and 5-day intervals, but there were no significant differences between groups in these comparisons
