Abstract:Objective To explore the therapeutic efficacy of guidewire-guided percutaneous transhepatic biliary drainage (PTBD) for acute obstructive suppurative cholangitis.Methods The clinical data of eighty-seven patients with acute obstructive suppurative cholangitis treated in our hospital from December 2018 to December 2021 were analyzed retrospectively. According to the approach of catheterization, the patients were divided into conventional puncture group (48 cases) and guidewire guidance group (39 cases). The patients in the conventional puncture group were treated with routine PTBD, and the patients in the guidewire guidance group were treated with guidewire-guided PTBD. The perioperative conditions of the two groups of patients, as well as changes of the liver function and the bilirubin level before and 1 week after the operation, serum and bile levels of cytokines before and 1 week after the operation, and the incidence of complications in the two groups of patients were observed.Results There was no significant difference in the operative duration, first-attempt success rate of catheterizationand daily drainage volume between the two groups (P > 0.05). The differences of the levels of TBIL, DBIL and ALT before and after the PTBD were not different between the two groups (P > 0.05), whereas the differences of the serum and bile levels of IL-1, IL-4, IL-10 and TNF-α of patients before and after the PTBD in the guidewire guidance group were greater than those in the conventional puncture group (P < 0.05). There was no significant difference in the incidence of biliary bleeding and bile leakage between the two groups (P > 0.05). The incidence of acute severe cholangitis and sepsis in the conventional puncture group was higher than that in the guidewire guidance group (P < 0.05).Conclusions The first-attempt success rate of catheterization in PTBD is comparable via conventional or guidewire-guided approaches. However, guidewire-guided PTBD well regulates the levels of inflammatory factors and reduces the incidence of postoperative acute severe cholangitis and sepsis.
