Laparoscopic surgery reduces the incidence of surgical site infections compared to the open approach for colorectal procedures: a meta-analysis.

ABSTRACT: BACKGROUND:Surgical site infections (SSI) are the commonest healthcare associated infections. They severely compromise patient safety, are a significant burden on healthcare resources and have an adverse impact on patient quality of life. The incidence of SSIs can be as high as 10% after colorectal procedures. The laparoscopic approach is being increasingly used to undertake colorectal procedures. It provides advantages over the traditional open approach with smaller incisions, shorter hospital stay and equal oncological outcomes. The aim of this meta-analysis was to evaluate whether the laparoscopic approach for colorectal procedures reduces the incidence of SSI compared to the open approach. METHODS:Randomised controlled trials (RCTs) comparing the two approaches published since 2000 were included in the review. Revman 5.3 software was used to carry out the review. Data were pooled and the results were shown as risk ratios with 95% confidence intervals using the fixed effects model. RESULTS:Sixteen RCT's were included in the analysis comprising 5797 patients. These covered a range of colorectal pathologies including colon cancer, rectal cancer, inflammatory bowel disease and familial adenomatous polyposis syndrome. Analysis showed significantly lower wound infection rates (RR: 0.72, 95% confidence interval: 0.60-0.88, p?=?0.001) and lower abdominal abscess rates (RR: 0.88, 95% CI 0.62-1.27, p?=?0.51). The combined SSI rate was significantly lower in laparoscopic compared to open surgery (RR: 0.76, 95% CI 0.64-0.90, p?=?0.001). CONCLUSIONS:Laparoscopic colorectal surgery significantly lowers the incidence of SSI compared to open surgery.

Project description:Importance:Colon surgery is associated with a high rate of surgical site infection (SSI), and there is an urgent need for strategies to reduce infection rates. Objective:To assess whether laparoscopic colon surgery is associated with a lower surgical site infection rate than open-approach laparoscopy, especially in patients with medically complex conditions. Design, Setting, and Participants:This cohort study used previously validated diagnosis and procedure codes from Medicare beneficiaries who underwent colon surgery from January 1, 2009, to November 30, 2013. Analyses were performed from August 1 to December 31, 2018. Main Outcomes and Measures:Outcome measures were SSI events, medical comorbidities, and laparoscopic or open approach procedures. Results:A total of 229 726 patients (mean [SD] age, 74.3 [9.4] years; 128 499 [55.9%] female) underwent colon procedures. There were 105 144 laparoscopic procedures and 124 582 open procedures. The overall mean SSI rate was 6.2%, varying by surgical procedure from 5.8% to 7.6%. Among the full study population, adjusted model results showed a significant association of laparoscopy with lower odds of SSI (odds ratio, 0.43; 95% CI, 0.41-0.46; P < .001). When stratified by surgical approach, the mean SSI rates were 4.1% (procedure-specific range, 3.9%-5.1%) for the laparoscopic approach and 7.9% (procedure-specific range, 7.4%-10.2%) for the open approach. When stratified by Elixhauser score groups, the mean SSI rates were 6.2% (procedure-specific range, 3.2%-8.7%) for group 1 (0-1 comorbidity), 5.5% (procedure-specific range, 3.6%-11.1%) for group 2 (2 comorbidities), and 6.6% (procedure-specific range, 4.6%-10.6%) for group 3 (3-13 comorbidities). An interaction was also observed between laparoscopic approach and Elixhauser groups, with increased odds of SSI among patients who had 3 to 13 comorbidities present at the time of the procedure (odds ratio, 1.21; 95% CI, 1.11-1.32) compared with patient groups with fewer comorbidities. The population attributable fraction of SSIs for use of the open approach was 34.2%. A total of 2317 of 3882 hospitals (59.7%) performed few (0%-10%) or most (>50%) procedures laparoscopically. Conclusions and Relevance:Policy changes that promote surgical education and resources for laparoscopy, especially at low-adoption hospitals, may be associated with reduced colon SSI rates. Support of the development of innovative educational policies may help achieve improvement in patient outcomes and decreased health care use in colon surgery.

Project description:ImportanceGynecological laparoscopies are one of the most common surgical procedures worldwide. Limited evidence exists on rates of surgical site infections in patients undergoing gynecological laparoscopies and strategies to prevent these infections.ObjectiveTo compare rates of port-site infections, organ or space infections, and any type of surgical site infections among patients who underwent gynecological laparoscopies and received 1 of 3 types of skin preparation solutions.Design, setting, and participantsA double-blind randomized clinical trial was conducted between February 28, 2017, and November 26, 2018, at a tertiary university-affiliated referral center. A total of 661 patients 18 years or older who underwent an elective operative laparoscopy for treatment of nonmalignant gynecological disorders were randomly assigned in a 1:1:1 ratio to have their skin cleaned before surgery with alcohol-based chlorhexidine, alcohol-based povidone-iodine, or water-based povidone-iodine. Statistical analysis was performed from February 28, 2017, to November 26, 2018. Analyses were performed on a modified intention-to-treat basis.InterventionsA total of 221 patients were randomized to have their skin prepared preoperatively with water-based povidone-iodine, 220 were randomized to alcohol-based povidone-iodine, and 220 were randomized to alcohol-based chlorhexidine. The patients were blinded to the solution used to clean their skin. Patients were followed up 1 and 4 weeks after surgery by a physician who was blinded to the skin preparation solution used at surgery. Evidence of infection according to Centers for Disease Control and Prevention criteria were documented.Main outcomes and measuresThe primary outcome of this study was port-site infection 30 days after surgery. Secondary outcomes were organ or space infections and any type of surgical site infections; the study also aimed to prospectively describe rates of surgical site infections in gynecological laparoscopies.ResultsOf the 661 patients, 640 (96.8%; mean [SD] age, 36.2 [10.6] years) were examined after surgery by a physician at the study site and were included in the modified intention-to-treat analysis. The overall rate of port-site infection was 10.2% (65 of 640), rate of organ or space infection was 6.6% (42 of 640), and rate of any surgical site infection was 16.3% (104 of 640). The odds ratio for port-site infection for alcohol-based chlorhexidine vs water-based povidone-iodine was 1.13 (95% CI, 0.61-2.08), for alcohol-based chlorhexidine vs alcohol-based povidone-iodine was 1.34 (95% CI, 0.71-2.52), and for water-based povidone-iodine vs alcohol-based povidone-iodine was 1.19 (95% 0.62-2.27).Conclusions and relevanceSurgical site infections were more common than expected among patients who underwent gynecological laparoscopies. No skin preparation solution provided an advantage compared with the other solutions in reducing infection rates.Trial registrationhttp://anzctr.org.au Identifier: ACTRN12617000475347.

Project description:BackgroundSurgical site infection is a devastating postoperative complication, and the occurrence ranges from 1% to 2% after total knee arthroplasty (TKA). The efficacy of the preoperative use of chlorhexidine for reducing infection has been debated. This meta-analysis aimed to examine the efficacy of the use of chlorhexidine to prevent surgical site infections after TKA.MethodsIn February 2017, a systematic literature review was conducted using the following electronic databases: PubMed, EMBASE, Web of Science, Cochrane Database of Systematic Reviews, and the Google database. Data from randomized controlled trials (RCTs) and retrospective comparative study (RCS) that compared the use of chlorhexidine versus control washes to prep patients for TKA were retrieved. The primary endpoint was to compare the total incidence of infection with and without the use of chlorhexidine. The secondary outcomes were the incidence of infection in low-risk category patients, moderate-risk category patients, and high-risk category patients. After testing for publication bias and heterogeneity between studies, data were aggregated for random-effects modeling when necessary.ResultsFour clinical trials that included 8787 patients (chlorhexidine group: n = 2615, control group: n = 6172) were ultimately included in the meta-analysis. Chlorhexidine was associated with a reduced total incidence of infection, corresponding to a reduction of 1.69% [risk ratio (RR) = 0.22; 95% confidence interval (95% CI) = 0.12-0.40; P = .000]. Similarly, chlorhexidine was associated with a reduction in the incidence of infection among patients in the moderate-risk category (RR, 0.18; 95% CI, 0.05-0.63; P = .007) and the high-risk category (RR, 0.13; 95% CI, 0.03-0.67; P = .014). There was no significant difference between the incidence of infection in low-risk category patients with chlorhexidine use compared with the use of control washes (RR, 0.60; 95% CI, 0.22-1.60; P = .330).ConclusionThe preoperative use of chlorhexidine could reduce the total incidence of infection and the incidence of infection in moderate-risk and high-risk category patients. The overall evidence and the number of included studies was limited; thus, a greater number of high-quality RCTs is still needed to further identify the effects of chlorhexidine on reducing the incidence of infection after TKA.
