Clinical Evaluation of Continuous Renal Replacement Therapy in Combination with Ultrasound-Guided Percutaneous Transhepatic Gallbladder Drainage for Acute Severe Biliary Pancreatitis: a Retrospective Study

BACKGROUND/AIMS: This study aimed to report the clinical efficacy of continuous renal replacement therapy (CRRT) in combination with ultrasound-guided percutaneous transhepatic gallbladder drainage (PTGD) (CRRT+PTGD) in the treatment of acute severe biliary pancreatitis (ASBP). METHODS: Between January 2010 and January 2016, 40 cases of patients with ASBP who received routine CRRT (CRRT group) and 40 of those who received CRRT+PTGD (CRRT+PTGD group) at the Affiliated Hospital of Qingdao University (Qingdao, China) were retrospectively reviewed. Clinical (including abdominal pain remission time, gastrointestinal decompression time, Intensive Care Unit (ICU) hospital stay, respirator treatment time, and mortality rate), laboratory (white blood cells [WBC], platelet [PLT], procalcitonin [PCT], C-reactive protein [CRP], total bilirubin [TBIL], alanine aminotransferase [ALT], albumin [ALB], and blood lactic acid [Lac]) parameters, various critical disease scores, and incidence of complications after the treatment were compared between the two groups. RESULTS: Compared with those in the routine CRRT group, patients in the CRRT+PTGD group exhibited significant remission of clinical symptoms (i.e. shorter abdominal pain remission time, gastrointestinal decompression time, respirator treatment time and ICU hospital stay) (all P<0.05), change of laboratory parameters (WBC, PLT, PCT, CRP, TBIL, ALT) (P<0.05), and improvement of various critical disease scores (P<0.05). Moreover, the variation of most of the above parameters after versus before the treatment was greater in the CRRT+PTGD group than in the CRRT group (all P<0.05). CONCLUSION: CRRT in combination with PTGD is more effective in the treatment of ASBP than CRRT alone.
