Systematic review and meta-analysis of the efficacy of prophylactic abdominal drainage in major liver resections.

ABSTRACT: Prophylactic drainage after major liver resection remains controversial. This systematic review and meta-analysis evaluate the value of prophylactic drainage after major liver resection. PubMed, Web of Science, and Cochrane Central were searched. Postoperative bile leak, bleeding, interventional drainage, wound infection, total complications, and length of hospital stay were the outcomes of interest. Dichotomous outcomes were presented as odds ratios (OR) and for continuous outcomes, weighted mean differences (MDs) were computed by the inverse variance method. Summary effect measures are presented together with their corresponding 95% confidence intervals (CI). The certainty of evidence was evaluated using the Grades of Research, Assessment, Development and Evaluation (GRADE) approach, which was mostly moderate for evaluated outcomes. Three randomized controlled trials and five non-randomized trials including 5,050 patients were included. Bile leakage rate was higher in the drain group (OR: 2.32; 95% CI 1.18-4.55; p?=?0.01) and interventional drains were inserted more frequently in this group (OR: 1.53; 95% CI 1.11-2.10; p?=?0.009). Total complications were higher (OR: 1.71; 95% CI 1.45-2.03; p?

Project description:ObjectivesTo conduct a systematic review and meta-analysis of the efficacy and safety of abdominal paracentesis drainage (APD) in patients with acute pancreatitis (AP) when compared with conventional 'step-up' strategy based on percutaneous catheter drainage (PCD).DesignSystematic review and meta-analysis.MethodsPubMed, EMBASE, Cochrane Library, MEDLINE (OVID), China National Knowledge Infrastructure and Wanfang Database were electronically searched to collect cohort studies and randomised controlled trials (RCTs) from inception to 25 July 2020. Studies related to comparing APD with conventional 'step-up' strategy based on PCD were included.OutcomesThe primary outcome was all-cause mortality. The secondary outcomes were the rate of organ dysfunction, infectious complications, hospitalisation expenses and length of hospital stay.ResultsFive cohort studies and three RCTs were included in the analysis. Compared with the conventional 'step-up' method, pooled results suggested APD significantly decreased all-cause mortality during hospitalisation (cohort studies: OR 0.48, 95% CI 0.26 to 0.89 and p=0.02), length of hospital stay (cohort studies: standard mean difference (SMD) -0.31, 95% CI -0.53 to -0.10 and p=0.005; RCTs: SMD -0.45, 95% CI -0.64 to -0.26 and p<0.001) and hospitalisation expenses (cohort studies: SMD -2.49, 95% CI -4.46 to -0.51 and p<0.001; RCTs: SMD -0.67, 95% CI -0.89 to -0.44 and p<0.001). There was no evidence to prove that APD was associated with a higher incidence of infectious complications. However, the incidence of organ dysfunction between cohort studies and RCTs subgroup slightly differed (cohort studies: OR 0.66, 95% CI 0.34 to 1.28 and p=0.22; RCTs: OR 0.58, 95% CI 0.35 to 0.98 and p=0.04).ConclusionsThe findings suggest that early application of APD in patients with AP is associated with reduced all-cause mortality, expenses during hospitalisation and the length of stay compared with the 'step-up' strategy without significantly increasing the risk of infectious complications. These results must be interpreted with caution because of the limited number of included studies as well as a larger dependence on observational trials.Prospero registration numberCRD42020168537.

Project description:To assess the efficacy of antimicrobial-impregnated catheters in preventing catheter-related infections during external ventricular drainage (EVD), we performed a meta-analysis and systematic review. We systematically searched Medline, Embase, and the Cochrane Library. All randomized controlled trials (RCTs) and nonrandomized prospective studies (NPSs) related to antimicrobial-impregnated EVD catheters were included. The primary outcome was the rate of cerebrospinal fluid infection (CFI). The secondary outcomes included the rate of time-dependent CFI and catheter bacterial colonization. We further performed subgroup analysis, meta-regression analysis, and microbial spectrum analysis. Four RCTs and four NPSs were included. The overall rate of CFIs was 3.6% in the antimicrobial-impregnated catheter group and 13.7% in the standard catheter group. The pooled data demonstrated that antimicrobial-impregnated catheters were superior to standard catheters in lowering the rate of CFIs (odds ratio (OR) = 0.25, 95% confidence interval (CI) = 0.12 to 0.52, P <0.05). In survival analysis, the 20-day infection rate was significantly reduced with the use of antimicrobial-impregnated catheters (hazard ratio = 0.52, 95% CI = 0.29 to 0.95, P <0.05). Furthermore, a significantly decreased rate of catheter bacterial colonization was noticed for antimicrobial-impregnated catheters (OR = 0.37, 95% CI = 0.21 to 0.64, P <0.05). In subgroup analyses, although significant results remained for RCTs and NPSs, a subgroup difference was revealed (P <0.05). Compared with standard catheters, a significantly lower rate of CFIs was noticed for clindamycin/rifampin-impregnated catheters (OR = 0.27, 95% CI = 0.10 to 0.73, P <0.05) and for minocycline/rifampin-impregnated catheters (OR = 0.11, 95% CI = 0.06 to 0.21, P <0.05). However, no statistical significance was found when compared with silver-impregnated catheters (OR = 0.33, 95% CI = 0.07 to 1.69, P = 0.18). In microbial spectrum analysis, antimicrobial-impregnated catheters were shown to have a lower rate of Gram-positive bacterial infection, particularly the coagulase-negative Staphylococcus. In conclusion, the use of antimicrobial-impregnated EVD catheters could be beneficial for the prevention of CFI and catheter bacterial colonization. Although antibiotic-coated catheters seem to be effective, no sufficient evidence supports the efficacy of silver-impregnated catheters.
