RESUMO
Objective:To analyze and predict the clinical efficacy of rigid choledochoscopic percutaneous transhepatic biliary fistulation (PTBF) lithotripsy for the treatment of hepatolithiasis.Methods:Databases including PubMed, Embase, Cochrane Library, Web of Science, CNKI, Wanfang were searched for literatures from January 1, 1990 to March 1, 2022 on rigid choledochoscopic PTBF lithotripsy for hepatolithiasis studies. The primary outcomes including the final clearance rate, recurrence rate and overall postoperative complication rate, were analyzed by the random effects model in meta analysis and Bayesian network. The Markov Chain Monte Carlo was used for evaluation and prediction.Results:Fifteen articles were ultimately included, involving 1 296 patients, of which 1 008 patients were clearly shown to have complex intrahepatic bile duct stones in the literature [divided into two groups, the percutaneous transhepatic one-step biliary fistulation (PTOBF) stone removal group ( n=568) and the percutaneous transhepatic two-step biliary fistulation (PTTBF) stone removal group ( n=440)]. The results of Bayesian single-arm meta-analysis showed that the final clearance rate, recurrence rate and overall postoperative complication rate of PTOBF for hepatolithiasis were 84.19% (95% HPD: 79.08%-88.93%), 15.79% (95% HPD: 11.01%-21.07%) and 10.85% (95% HPD: 7.93%-14.21%). For complex hepatolithiasis, the final clearance rate, recurrence rate and overall postoperative complication rate of PTOBF were 82.58% (95% HPD: 75.46%-88.83%), 17.99% (95% HPD: 11.51%-25.45%), 10.34% (95% HPD: 6.42%-15.40%). For PTTBF, they were respectively 73.56% (95% HPD: 65.67%-80.30%), 29.48% (95% HPD: 23.13%-36.01%), 11.42% (95% HPD: 6.18%-17.67%). In comparison to PTTBF, the patients treated with PTOBF has a higher clearance rate ( OR=1.74, 95% CI: 1.17-2.60) and a lower recurrence rate ( OR=0.56, 95% CI: 0.37-0.84)but the overall complication rate did not improve ( OR=1.03, 95% CI: 0.66-1.62). Conclusions:Rigid choledochoscopic PTBF lithotripsy for hepatolithiasis is safe, effective and feasible. For complex hepatolithiasis, PTOBF has a higher clearance rate and a lower recurrence rate.
RESUMO
Three patients received surgical treatment in Department of Hepatobiliary Surgery of Mengchao Hepatobiliary Hospital from December 2020 to February 2022. Ceftriaxone sodium was given prophylactically before and after operation,and gallbladder silt stones were found by imaging examination on the 3rd, 3rd and 2nd after surgery in 3 patients, respectively. No special treatment was given,after the withdrawal of ceftriaxone sodium for 28, 38 and 48 d,radiographic examination showed that calculi disappeared spontaneously. It is suggested that the pseudolithiasis may be related to administration of ceftriaxone sodium.
