Analysis of the risk factors related to prolonged drainage time in patients with selective abdominal drainage after laparoscopic cholecystectomy / 中华肝胆外科杂志

ABSTRACT

Objective:To determine the risk factors of drainage time longer than 1 day in patients with selective abdominal drainage after laparoscopic cholecystectomy.Methods:The clinical data related to patients with selective abdominal drainage undergoing laparoscopic cholecystectomy from November 2009 to November 2019 at Chinese PLA General Hospital were retrospectively analyzed. Of 233 patients enrolled into this study, there were 147 males and 86 females, with a median aged 59.0 (47.5, 65.5) years old. The patients were divided into drainage time 1 day group of 65 patients and longer than 1 day group of 168 patients according to postoperative drainage time. The baseline data and perioperative data were collected, the risk factors correlated with drainage time longer than 1 day were analyzed.Results:The drainage time was 1 in the 1 day group and 2~8 in another group. Among the 233 patients, there was one with biliary leakage and 14 patients had abdominal bleeding, all of them healed after 2~3 days. All of the 233 patients were recovered when discharged. Independent risk factors related to drainage time longer than 1 day include BMI≥28 kg/m 2 ( OR=3.443, 95% CI 1.411-8.405, P=0.007), operation time ≥65 min ( OR=2.570, 95% CI 1.310-5.045, P=0.006), thickness of gallbladder wall ≥0.5 cm ( OR=12.720, 95% CI 1.350-5.478, P=0.005), postoperative stomachache ( OR=13.537, 95% CI 1.685-108.748, P=0.014) and postoperative fever ( OR=8.156, 95% CI 1.035-64.249, P=0.046). Conclusion:For patients undergoing selective abdominal drainage after laparoscopic cholecystectomy with BMI ≥28 kg/m 2, operation time ≥65 min, gallbladder wall thickness ≥0.5 cm, postoperative abdominal pain and fever, clinicians should appropriately prolong the drainage time to ensure medical safety.
