Table 4 Comparison between patients undergoing surgery at ≤ 7 and ≥ 7 days following PTGBD

From: The influence of the interval between percutaneous transhepatic gallbladder drainage and cholecystectomy on perioperative outcomes: a retrospective study

Gender (Male), n (%) 7 (58.3) 7 (70.0) 0.5696
Age (years) 74.8 ± 2.9 77.8 ± 3.1 0.4794
Comorbidity (Yes), n (%) 8 (66.7) 10 (100.0) 0.0181
Anticoagulant medication (Yes), n (%) 1 (8.3) 1 (10.0) 0.8925
ASA status 2.33 ± 0.19 2.40 ± 0.21 0.8195
Cholecystitis grade 1.9 ± 0.2 1.5 ± 0.2 0.1257
WBC before PTBGD (/mL) 13,355 ± 1952 13,892 ± 2138 0.8549
CRP before PTGBD (mg/dL) 19.38 ± 3.01 14.06 ± 3.30 0.2480
WBC before surgery (/mL) 10,064 ± 1638 7948 ± 1795 0.3942

Hospitalization after surgery (days) 12.0 ± 5.4 24.2 ± 5.9 0.1406

  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
