Percutaneous Transhepatic Gallbladder Drainage Combined with Laparoscopic Cholecystectomy Versus Emergency Laparoscopic Cholecystectomy for the Treatment of Moderate Acute Cholecystitis: A Meta-Analysis.

We compared the clinical outcomes of laparoscopic cholecystectomy (LC) after percutaneous transhepatic gallbladder drainage (PTGBD) with those of emergency LC (ELC) in patients with moderate acute cholecystitis (AC) as per the Tokyo Guidelines. A meta-analysis of clinical comparative studies investigating the efficacy of PTGBD combined with LC (PTGBD + LC) versus ELC for moderate AC patients was performed. The PTGBD + LC group had a shorter operative time (mean difference [MD] = -25.02 minutes; 95% confidence interval [95% CI] -35.50 to -14.54;  < .00001), less intraoperative bleeding (MD = -33.38 mL; 95% CI -45.43 to -21.33;  < .00001), shorter postoperative hospital stay (MD = -2.37 days; 95% CI -3.30 to -1.44;  < .00001), lower conversion rate (odds ratio [OR] 0.23; 95% CI 0.11-0.48;  < .0001), and lower total postoperative morbidity (OR 0.26; 95% CI, 0.10-0.67;  = .005) compared with the ELC group. There was no significant difference in total hospital stay (MD = 1.71 days; 95% CI -0.17 to 3.60;  = .08) and the incidence of bile leak (OR 0.30; 95% CI 0.07-1.29;  = .11). Compared with ELC, LC after PTGBD can effectively reduce the difficulty of operation, total postoperative morbidity, and conversion rate, and shorten the postoperative hospital stay and operative duration in patients with moderate AC as per the Tokyo Guidelines. In clinical practice, it is necessary to formulate individualized treatment plans based on the condition and willingness of the patients.
