Meta-Analysis Review
BACKGROUND
There is some evidence to suggest that discharge education may reduce the risk of postoperative complications, however, a critical evaluation of the body of evidence is needed.
OBJECTIVE
To assess the effect of discharge education interventions versus standard education given to general surgery patients prior to, or up to 30-days of hospital discharge on clinical and patient-reported outcomes.
DESIGN
Systematic review and meta-analysis. Clinical outcomes were 30-day surgical site infection incidence and re-admission up to 28 days. Patient-reported outcomes included patient knowledge, self-confidence, satisfaction, and quality of life.
SETTING
Participants were recruited from hospitals.
PARTICIPANTS
Adult general surgical patients.
METHODS
MEDLINE (Pubmed), CINAHL (EBSCO), EMBASE (Elsevier) and the Cochrane Library were searched in February 2022. Randomised controlled trials and non-randomised studies of interventions published between 2010 and 2022, with adults undergoing general surgical procedures receiving discharge education on surgical recovery, including wound management, were eligible for inclusion. Quality appraisal was undertaken using the Cochrane Risk of Bias 2 and the Risk of Bias Assessment Tool for Nonrandomised Studies. The Grading of Assessment, Development, Recommendations, and Evaluation was used to assess the certainty of the body of evidence based on the outcomes of interest.
RESULTS
Ten eligible studies (eight randomised control trials and two non-randomised studies of interventions) with 965 patients were included. Six randomised control trials assessed the effect of discharge education interventions on 28-day readmission (Odds ratio 0.88, 95 % confidence interval 0.56-1.38). Two randomised control trials assessed the effect of discharge education interventions on surgical site infection incidence (Odds ratio = 0.84, 95 % confidence interval 0.39-1.82). The results of the non-randomised studies of interventions were not pooled due to heterogeneity in outcome measures. The risk of bias was either moderate or high for all outcomes, and the body of evidence using GRADE was judged as very low for all outcomes studied.
CONCLUSIONS
The impact of discharge education on the clinical and patient-reported outcomes of patients undergoing general surgery cannot be determined due to the uncertainty of the evidence base. Despite the increased use of web-based interventions to deliver discharge education to general surgery patients, larger samples in more rigorous multicentre randomised control trials with parallel process evaluations are needed to better understand the effect of discharge education on clinical and patient-reported outcomes.

INTRODUCTION
Limited evidence has been reported for surgical site infections (SSIs) in patients undergoing surgery who are carriers of extended-spectrum cephalosporin-resistant Enterobacterales (ESCR-E). A systematic review and meta-analysis were conducted to evaluate the risk of postoperative infections in adult inpatients colonised with ESCR-E before surgery.
METHODS
The Medline, Embase and Cochrane databases were searched between January 2011 and April 2022, following PRISMA indications. Random effects meta-analysis was used to quantify the association between ESCR-E colonisation and infection.
RESULTS
Among the 467 articles reviewed, 9 observational studies encompassing 7219 adult patients undergoing surgery were included. The ESCR-E colonisation rate was 13.7% (95% CI 7.7-19.7). The most commonly reported surgeries included abdominal surgery (44%) and liver transplantation (LT; 33%). The SSI rate was 23.2% (95% CI 13.2-33.1). Pooled incidence risk was 0.36 (95% CI 0.22-0.50) vs 0.13 (95% CI 0.02-0.24) for any postoperative infection and 0.28 (95% CI 0.18-0.38) vs 0.17 (95% CI 0.07-0.26) for SSIs in ESCR-E carriers vs noncarriers, respectively. In ESCR-E carriers, the ESCR-E infection ratio was 7 times higher than noncarriers. Postoperative infection risk was higher in carriers versus noncarriers following LT. Sources of detected heterogeneity between studies included ESCR-E colonisation and the geographic region of origin.
CONCLUSIONS
Patients colonised with ESCR-E before surgery had increased incidence rates of post-surgical infections and SSIs compared to noncarriers. Our results suggest considering the implementation of pre-surgical screening for detecting ESCR-E colonisation status according to the type of surgery and the local epidemiology.

Meta-Analysis Review
OBJECTIVE
Despite the improvements in xenogeneic grafts and surgical techniques, management of aortic graft infection has remained challenging. The optimal graft material has remained controversial, with high rates of reinfection using prosthetic grafts and a limited time for venous harvest in an emergent setting. Recent studies have highlighted an increase in the use of Omniflow II biosynthetic vascular grafts (LeMaitre Vascular, Burlington, MA) for aortic reconstruction. The primary aim of the present study was to review the key outcomes for the Omniflow II graft in terms of reinfection and complications.
METHODS
The National Healthcare Service healthcare databases advanced search function was used to search nine databases for the search term "Omniflow." The present study complied with the PRISMA (preferred reporting items for systematic review and meta-analysis) statement. Eligible studies related to aortic graft infection or in situ aortic reconstruction were selected in accordance with prespecified eligibility criteria and included for review. Data on the surgical technique, comorbidities, graft reinfection, mortality, and complications were combined. The data were analyzed using Stata/MP, version 17 (StataCorp, College Station, TX), and the probabilities were pooled using a DerSimonian and Laird random effects model with Freeman-Tukey arcsine transformation.
RESULTS
Six studies with 60 patients (44 men; age range, 29-89 years) were included. Of the 60 patients, 25 had undergone surgical reconstruction because of early graft infection (<4 months after the index procedure), 24 for late graft infection, and 3 because of mycotic aneurysms. Eight high-risk patients had undergone surgical reconstruction for prevention of an initial graft infection. Staphylococcus aureus, Escherichia coli, and S. epidermis were the most common organisms. Early mortality was 8.83% (95% confidence interval [CI], 1.12%-20.53%), and late mortality was 18.49% (95% CI, 5.51%-35.34%). Follow-up varied from 9 months to 2 years. No graft rupture or graft degeneration had occurred during follow-up. However, 6.2% (95% CI, 0.39%-15.81%) had experienced early graft occlusion, and 3.83% (95% CI, 0.00%-16.34%) had developed early graft stenosis. Two cases of postoperative reinfection were reported. The freedom from reinfection was 97.71% (95% CI, 87.94%-100.00%).
CONCLUSIONS
Use of the Omniflow II graft for aortic reconstruction is a feasible alternative with acceptable mortality and low reinfection rates. However, there is a risk of limb occlusion. Although these studies were of low quality, the Omniflow II graft shows promise in this difficult patient cohort, especially when bifurcated reconstruction is required.

BACKGROUND
Surgical site infections (SSIs) in children represent a common and serious postoperative complication. Surgical skin preparation is an essential preventive measure in every surgical procedure. The most commonly used antiseptic agents for surgical skin preparation are chlorhexidine gluconate and iodophors in alcohol-based solutions. In adult patients the use of chlorhexidine-containing antiseptic solutions for preoperative skin preparation has been advocated to reduce SSI rates. Our objective was to conduct a systematic literature review on use of antiseptic agents for surgical skin preparation in children less than 16 years of age.
METHODS
A systematic review of MEDLINE, EMBASE, CINAHL and CENTRAL was performed using both MeSH and free text terms and using the relevant Cochrane filter to identify full text randomized trials (RCTs) and comparative observational studies. Interventions of interest were the choice of main agent in antiseptic solutions (chlorhexidine/povidone-iodine/alcohol) compared with each other or with other antiseptic agents. Primary outcome was the reported rate of surgical site infections.
RESULTS
In total 8 studies were included in the review; 2 RCTs and 6 observational studies. Observational studies generally did not primarily investigate the association of different antiseptics with subsequent SSI. The identified randomised controlled trials included only 61 children in total, and were of low quality. Consequently, we did not conduct a formal meta-analysis. Since the publication of a comprehensive systematic review of perioperative measures for the prevention of SSI in 2016, no randomized controlled trials comparing antiseptic agents for surgical skin preparation in paediatric surgery have been conducted.
CONCLUSION
Robust evidence on the optimal skin antisepsis to reduce SSIs in children is lacking. Direct extrapolation of effects from trials involving adults is not appropriate as physiologic characteristics and risk factors for SSIs differ between adults and children. It is therefore essential to conduct high quality RCT investigating interventions to identify optimal measures to reduce SSI rates in children.

Meta-Analysis Review
BACKGROUND
Postoperative sore throat and other airway morbidities are common and troublesome after endotracheal tube intubation general anesthesia (ETGA). We propose lidocaine as endotracheal tube (ETT) cuff inflation media to reduce the postintubation-related emergence phenomenon.
METHODS
We searched PubMed, EMBASE, and Cochrane databases systematically for randomized controlled trials (RCTs) that have investigated the outcome of intracuff lidocaine versus air or saline in patients receiving ETGA. Using a random-effects model, we conducted a meta-analysis to assess the relative risks (RRs) and mean difference (MD) of the incidence and intensity of relevant adverse outcomes.
RESULTS
We reviewed nineteen trials, which comprised 1566 patients. The incidence of early- and late-phase postoperative sore throat (POST), coughing, agitation, hoarseness, and dysphonia decreased significantly in lidocaine groups, with RRs of 0.46 (95% confidence interval [CI]: 0.31 to 0.68), 0.41 (95% CI: 0.25 to 0.66), 0.43 (95% CI: 0.31 to 0.62), 0.37 (95% CI: 0.25 to 0.55), 0.43 (95% CI: 0.29 to 0.63), and 0.19 (95% CI: 0.08 to 0.5), respectively, when compared with the control groups. The severity of POST also reduced significantly (mean difference [MD] -16.43 mm, 95% CI: -21.48 to -11.38) at 1 h and (MD -10.22 mm, 95% CI: -13.5 to -6.94) at 24 h. Both alkalinized and non-alkalinized lidocaine in the subgroup analyses showed significant benefits in emergence phenomena prevention compared with the control.
CONCLUSION
Our results indicate that both alkalinized and non-alkalinized intracuff lidocaine may prevent and alleviate POST and postintubation-related emergence phenomena.

UPDATES
This is the second version (first update) of the living systematic review, replacing the previous version (available as a data supplement). When citing this paper please consider adding the version number and date of access for clarity.
OBJECTIVE
To determine and compare the effects of drug prophylaxis on severe acute respiratory syndrome coronavirus virus 2 (SARS-CoV-2) infection and coronavirus disease 2019 (covid-19).
DESIGN
Living systematic review and network meta-analysis (NMA).
DATA SOURCES
World Health Organization covid-19 database, a comprehensive multilingual source of global covid-19 literature to 4 March 2022.
STUDY SELECTION
Randomised trials in which people at risk of covid-19 were allocated to prophylaxis or no prophylaxis (standard care or placebo). Pairs of reviewers independently screened potentially eligible articles.
METHODS
After duplicate data abstraction, we conducted random-effects bayesian network meta-analysis. We assessed risk of bias of the included studies using a modification of the Cochrane risk of bias 2.0 tool and assessed the certainty of the evidence using the grading of recommendations assessment, development and evaluation (GRADE) approach.
RESULTS
The second iteration of this living NMA includes 32 randomised trials which enrolled 25 147 participants and addressed 21 different prophylactic drugs; adding 21 trials (66%), 18 162 participants (75%) and 16 (76%) prophylactic drugs. Of the 16 prophylactic drugs analysed, none provided convincing evidence of a reduction in the risk of laboratory confirmed SARS-CoV-2 infection. For admission to hospital and mortality outcomes, no prophylactic drug proved different than standard care or placebo. Hydroxychloroquine and vitamin C combined with zinc probably increase the risk of adverse effects leading to drug discontinuation—risk difference for hydroxychloroquine (RD) 6 more per 1000 (95% credible interval (CrI) 2 more to 10 more); for vitamin C combined with zinc, RD 69 more per 1000 (47 more to 90 more), moderate certainty evidence.
CONCLUSIONS
Much of the evidence remains very low certainty and we therefore anticipate future studies evaluating drugs for prophylaxis may change the results for SARS-CoV-2 infection, admission to hospital and mortality outcomes. Both hydroxychloroquine and vitamin C combined with zinc probably increase adverse effects.

Review
BACKGROUND
Colectomy for ulcerative colitis is associated with short- and long-term complications. Estimates of the frequency of such complications are variable and may have changed since the introduction of biological therapy. Understanding the true burden of surgical complications is important to clinicians in assessing risks and benefits of colectomy vs. continued medical therapy.
AIM
To ascertain the outcomes of colectomy and ileal pouch surgery in patients with ulcerative colitis in the biologics era.
METHODS
Embase, MEDLINE and The Cochrane Library were searched for studies (2002-2015) reporting the outcomes of colorectal procedures (total and subtotal colectomy, IPAA with J-, S-, W-pouch) in adults with ulcerative colitis. Conferences proceedings (2011-2015) were hand-searched.
RESULTS
We identified 28 studies (20,801 patients) reporting outcomes from procedures conducted from 2002-2015. Early complications (≤30 days post-operatively), reported in 10 studies, occurred in 9-65% of patients with ulcerative colitis; late complications (>30 days post-operatively) occurred in 17-55% of patients. Most frequent short-term complications: infectious complications and ileus (mean incidence 20% and 18%). Most frequent long-term complications: pouchitis, faecal incontinence and small bowel obstruction (mean incidence 29%, 21% and 17%). Rates of early infection and late pouch failure decreased from 22% and 13% in 2002-2009 to 11% and 2% in 2010-2015. The mean incidence of post-operative mortality was 1.0% across 11 studies.
CONCLUSIONS
Early and late complications arise in about one-third of patients undergoing surgery for ulcerative colitis. While colorectal surgical procedures are recommended for a specific group of patients, the post-operative complications associated with these procedures should not be underestimated.

Meta-Analysis Review
BACKGROUND
The purpose of this systematic review and meta-analysis of randomized controlled trials (RCTs) was to evaluate whether intravenous steroids would result in reduced acute pain and postoperative nausea and vomiting (PONV) among patients undergoing total knee arthroplasty (TKA).
METHODS
Electronic databases, including PubMed, Embase, Web of Science, and the Cochrane Library, were searched to identify articles published from database inception to July 2016. RCTs that compared the effects of intravenous steroids with the effects of placebo among patients undergoing TKA were included in this meta-analysis. The primary outcomes were visual analogue scale (VAS) scores after 12, 24, and 48 hours of rest and PONV incidence. The secondary outcomes were blood glucose levels and incidence of infection. We calculated the risk ratio (RR) with its corresponding 95% confidence interval (CI) for dichotomous outcomes and the mean difference (MD) with its corresponding 95% CI for continuous outcomes.
RESULTS
Seven clinical trials involving 434 patients were included in the final meta-analysis. The pooled results indicated that intravenous steroids were associated with decreased VAS scores after 24 hours (MD = -10.21, 95%CI = -18.80 to -1.63, P = .020) and 48 hours (MD = -2.60, 95%CI = -4.70 to -0.50, P = .015) of rest. Moreover, intravenous steroids were also associated with decreased risk of nausea (RR = 0.58, 95% CI 0.44-0.77, P = .000) and vomiting (RR = 0.46, 95% CI = 0.24-0.88, P = .019). However, intravenous steroids were also associated with increased blood glucose levels. No significant difference in the risk of infection was identified between the 2 groups.
CONCLUSION
Intravenous steroids may be associated with decreased pain intensity and decreased risk of nausea and vomiting during the early period following TKA. However, evidence supporting its use is limited by the low quality of and variations in dosing regimens between the included RCTs. Thus, more high-quality RCTs are needed to identify the optimal drug administration intervals for maximal pain control.

Meta-Analysis
PURPOSE
Periprosthetic joint infection (PJI) is a serious complication with total joint arthroplasty (TJA), that necessitates reoperation. Pre-closure irrigation with dilute povidone-iodine (PI) is among the preventive measures, but its efficiency is still controversial. As a result, the focus of this systematic review and meta-analysis is on the effect of dilute PI wound irrigation in the prevention of PJI following TJA.
METHODS
We systematically reviewed and analyzed articles that compared PI with other agents in terms of PJI rate after TJA, searching Medline, Scopus, Web of science, and Cochrane databases. A number of 13 papers including 63,950 patients in total, were finally considered in qualitative and quantitative assessments. We have also further assessed review articles.
RESULTS
In comparison with normal saline (NS), PI reduced post-operative infection rate (OR: 0.44; CI 95%: 0.34-0.56). However, there was no difference between PI and chlorhexidine (CHG) (OR: 1.61; CI 95%: 0.83-3.09)) or undetermined comparators (OR: 1.08; CI 95%: 0.67-1.76).
CONCLUSION
PI irrigation seems an efficient preventive measure for post-operative PJI and would seem to be the most feasible for TJA protocol.

Meta-Analysis
BACKGROUND
A systematic review and meta-analysis were performed to explore the adoption value of electronic bronchoscopy (EBS) in the diagnosis and treatment of refractory pneumonia and to provide a theoretical basis for the clinical bronchoscopy treatment of patients.
METHODS
Randomized controlled trials of treatment-resistant pneumonia searched on PubMed, Embase, and other websites before December 31, 2020 were collected. Literature was selected by inclusion and exclusion criteria. Bias risk was assessed using Cochrane intervention system Review manual 5.0.2 and Review Manager 5.3.
RESULTS
A total of 6 articles meeting the requirements were included, comprising 796 participants. The results of meta-analysis showed that the clinical efficacy [odds ratio (OR) =3.8; 95% confidence interval (CI): 1.11-12.99; Z=2.13; P =0.03] and white blood cell counts [mean difference (MD) =0.55; 95% CI: -0.57 to 1.67; Z=0.96; P=0.34] of patients both increased. The mortality rate (OR =0.7; 95% CI: 0.3-1.63; Z=0.82; P=0.41), the incidence of infection (OR =0.84; 95% CI: 0.5-1.39; Z=0.69; P=0.49), ICU hospitalization days (OR =0.59; 95% CI: 0.36-0.98; Z=2.04; P=0.04), days of antibiotic use (OR =0.39; 95% CI: 0.18-0.84; Z=2.41; P=0.02), body temperature (MD =-0.2; 95% CI: -0.24 to 0.16; Z=9.5; P<0.0001), and the PaO2:FIO2 ratio (MD =-9.96; 95% CI: -13.31 to -6.61; Z=5.83; P<0.0001) of patients in the experimental group were lower than those of the control group. Differences in white blood cell count, mortality rate, and incidence of infection of patients in the experimental group were not statistically significant compared with those in the control group.
DISCUSSION
EBS adopted in the diagnosis and treatment of refractory pneumonia can reduce the occurrence of postoperative adverse reactions, reduce the infection rate, and effectively improve the clinical symptoms. It is therefore suitable for the treatment of this disease.
