Meta-Analysis Review
OBJECTIVE
To verify the effectiveness of noninvasive ventilation compared to conventional physiotherapy or oxygen therapy in the mortality rate and prevention of pulmonary complications in patients during the immediate postoperative period of cardiac surgery.
METHODS
Systematic review and meta-analysis recorded in the International Prospective Register of Ongoing Systematic Reviews (number CRD42016036441). The research included the following databases: MEDLINE, Cochrane Central, PEDro, LILACS and manual search of the references of studies published until March 2016. The review included randomized controlled trials with patients during the immediate postoperative period of cardiac surgery, which compared the use of noninvasive ventilation, BiLevel modes, continuous positive airway pressure, intermittent positive pressure breathing and positive pressure ventilation with conventional physiotherapy or oxygen therapy, and assessed the mortality rate, occurrence of pulmonary complications (atelectasis, pneumonia, acute respiratory failure, hypoxemia), reintubation rate, ventilation time, time spent in the intensive care unit (ICU), length of hospital stay and partial pressure of oxygen.
RESULTS
Among the 479 selected articles, ten were included in the systematic review (n=1050 patients) and six in the meta-analysis. The use of noninvasive ventilation did not significantly reduce the risk for atelectasis (RR: 0.60; CI95% 0.28-1.28); pneumonia (RR: 0.20; CI95% 0.04-1.16), reintubation rate (RR: 0.51; CI95%: 0.15-1.66), and time spent in the ICU (-0.04 days; CI95%: -0.13; 0.05).
CONCLUSION
Prophylactic noninvasive ventilation did not significantly reduce the occurrence of pulmonary complications such as atelectasis, pneumonia, reintubation rate and time spent in the ICU. The use is still unproven and new randomized controlled trials should be carried out.

Meta-Analysis
Effects of preoperative anti-tumour necrosis factor alpha infusion timing on postoperative surgical site infection in inflammatory bowel disease: A systematic review and meta-analysis.
BACKGROUND
Anti-tumour necrosis factor alpha agents (anti-TNF-α) have been widely used in patients with inflammatory bowel disease (IBD). However, few published meta-analyses have focused on timing of the last infusion before surgery. We evaluated the relationship between preoperative anti-TNF-α timing and postoperative surgical site infection to provide additional evidence for surgeons to choose appropriate dates for surgery.
METHODS
We searched from inception until January 2019 for studies that documented postoperative complications of adults with IBD who underwent preoperative anti-TNF-α treatment. Primary outcomes of included studies were the odds ratios of preoperative anti-TNF-α time frames (4, 8 and 12 weeks). In addition, surgical site infection and its subtypes (anastomotic leakage, abscesses and wound infection) were analysed.
RESULTS
Twenty-seven publications were included. No significant difference between anti-TNF-α and control cohorts was observed for most postoperative surgical site infections (or its subtypes) when the preoperative anti-TNF-α infusion time window was within 4, 8 or 12 weeks. Additionally, no significant difference in postoperative complications was observed between preoperative anti-TNF-α windows of within four weeks and more than four weeks.
CONCLUSIONS
In terms of surgical site infection and its subtypes, anti-TNF-α may be safe for ulcerative colitis and Crohn's disease patients who receive their last infusion of anti-TNF-α more than four weeks before surgery. We also found no evidence that anti-TNF-α was a risk factor when administered within four weeks, with the exception of subgroup results from a single study. Stratified by time window, use of anti-TNF-α until surgery has the potential to become a more considered strategy in clinical practice.

Corneal crosslinking is a U.S. Food and Drug Administration--approved therapy to stiffen the cornea and prevent progression of corneal ectasia in patients with keratoconus. The standard procedure involves removal of the corneal epithelium (epithelial-off) prior to treatment. Variations to the standard procedure include accelerated crosslinking and transepithelial procedures. This study reviewed what is known regarding the risk for infection after epithelial-off crosslinking, the spectrum of pathogens, and clinical outcomes. 26 publications were identified. All eyes were fit with a bandage contact lens postoperatively. Available data indicate that the overall frequency of infectious keratitis after epithelium-off crosslinking is low. Bacterial infections are the most common, with a mean time of presentation of 4.8 days postoperatively. The use of steroids and bandage contact lenses in the immediate postoperative period and/or a history of atopic or herpetic disease were associated with infection. These patients require intense postoperative care with prophylactic antiviral therapy when appropriate.

Meta-Analysis
Postoperative wound infection in dermatologic surgery causes impaired wound healing, poor cosmetic outcome and increased morbidity. Patients with a high-risk profile may benefit from perioperative antibiotic prophylaxis. The objective of this systematic review was to identify risk factors for surgical site infection after dermatologic surgery. In this article, we report findings on patient-dependent risk factors. The literature search included MEDLINE, EMBASE, CENTRAL and trial registers. We performed meta-analysis, if studies reported sufficient data to calculate risk ratios with 95% confidence intervals. Study quality was assessed according to the Newcastle-Ottawa-Scale. Seventeen observational studies that analysed 31213 surgical wounds were eligible for inclusion. Fourteen studies qualified for meta-analysis. Nine studies showed good, three fair and five poor methodological quality. The reported incidence of surgical site infection ranged from 0.96% to 8.70%. Meta-analysis yielded that male gender and immunosuppression were significantly associated with higher infection rates. There was a tendency towards a higher infection risk for patients with diabetes, without statistical significance. Meta-analysis did not show different infection rates after excision of squamous cell carcinoma or basal cell carcinoma, but studies were substantially heterogenous. There was no significant association between risk for wound infection and smoking, age over 60 years, oral anti-aggregation or anti-coagulation or excision of malignant melanoma. In conclusion, the risk for surgical site infection in dermatologic surgery is low. Infection rates were increased significantly in male as well as immunosuppressed patients and non-significantly in diabetics.

Review
OBJECTIVE
Dialkylcarbomoyl chloride (DACC)-coated dressings (Leukomed Sorbact and Cutimed Sorbact) irreversibly bind bacteria at the wound surface that are then removed when the dressing is changed. They are a recent addition to the wound care professional's armamentarium and have been used in a variety of acute and chronic wounds. This systematic review aims to assess the evidence supporting the use of DACC-coated dressings in the clinical environment.
METHOD
We included all reports of the clinical use of DACC-coated dressings in relation to wound infection. Medline, Embase, CENTRAL and CINAHL databases were searched to September 2016 for studies evaluating the role of DACC-coated dressings in preventing or managing wound infections.
RESULTS
We identified 17 studies with a total of 3408 patients which were included in this review. The DACC-coating was suggested to reduce postoperative surgical site infection rates and result in chronic wounds that subjectively looked cleaner and had less bacterial load on microbiological assessments.
CONCLUSION
Existing evidence for DACC-coated dressings in managing chronic wounds or as a surgical site infection (SSI) prophylaxis is limited but encouraging with evidence in support of DACC-coated dressings preventing and treating infection without adverse effects.

Meta-Analysis Review
OBJECTIVES
To describe the different types of episiotomy and to define the methods of repair.
METHODS
A systematic review on Medline and Cochrane Database between 1980 and August 2005 was performed.
RESULTS
Aseptic prevention and specific material may be used in order to reduce the risk of surgical wound infection (grade C). Episiotomy and perineal repair may be associated with considerable pain. In contrast, there has been little evaluation of the effectiveness of analgesia provided to women undergoing this procedure. The mediolateral episiotomy is a 6 cm incision at a 45 degrees angle from the inferior portion of the hymeneal ring (professional agreement). However, shorter length and lower angled episiotomies are also currently reported for routine practice (grade C). There are no data to recommend preferential use of an absorbable synthetic material (acid polyglycolic versus polyglactin 910). The use for the more rapid polylactin 910 suture material was associated with less need to remove sutures but with more wound gapping in comparison with the standard polyglactin 910 material (grade A). The continuous subcuticular technique of perineal repair may be associated with less pain in the immediate postpartum period than the interrupted technique (grade A).
CONCLUSION
Mediolateral episiotomy is the method of choice in France. However, the procedure for this technique should be studied more. Subcuticular technique with an absorbable synthetic material may be the optimal method of repair.

Review
The purpose of the study was to perform a systematic review and meta-analysis of the literature to compare the efficacy (and other postoperative outcomes) of nonabsorbable versus absorbable nasal packing after functional endoscopic sinus surgery (FESS) for the treatment of chronic rhinosinusitis. Studies were considered for inclusion if they were published in English language, were randomized clinical trials, and reported on outcomes following postoperative synechia. The primary outcome for meta-analysis was the incidence of postoperative synechia; pooled odds ratios (ORs) and 95 % confidence intervals (CIs) were calculated using fixed-effects models. Five studies, involving 241 nasal cavities in each treatment group, were included in the systematic review. The prevalence of synechia ranged from 4.6 to 8.0 % in the absorbable groups and from 8.0 to 35.7 % in the nonabsorbable groups. Postoperative bleeding was lower in the absorbable groups, whereas there was no clear finding regarding postoperative pain. Postoperative edema was generally similar between groups. There were no consistent findings regarding bleeding and pain on packing removal. Two studies using the same type of packing material were included in the meta-analysis. The combined OR (0.33, 95 % CI 0.04-2.78) for postoperative synechia did not significantly favor (P = 0.308) absorbable packing over nonabsorbable packing. Although there is some evidence in the available literature that absorbable nasal packing may provide superior outcomes to nonabsorbable packing after FESS, the lack of homogeneity between studies makes definitive conclusions impossible. Further randomized clinical trials are needed to compare the efficacy of different types of absorbable nasal packing for preventing synechia after FESS.

Meta-Analysis Review
INTRODUCTION
The COVID-19 pandemic has had a significant impact on global surgery. In particular, deleterious effects of SARS-CoV-2 infection on the heart and cardiovascular system have been described. To inform surgical patients, we performed a systematic review and meta-analysis aiming to characterize outcomes of COVID-19 positive patients undergoing cardiac surgery.
METHODS
The study protocol was registered with PROSPERO (CRD42021228533) and conformed with PRISMA 2020 and MOOSE guidelines. PubMed, Ovid MEDLINE and Web of Science were searched between 1 January 2019 to 24 February 2022 for studies reporting outcomes on COVID-19 positive patients undergoing cardiac surgery. Study screening, data extraction and risk of bias assessment were conducted in duplicate. Meta-analysis was conducted using a random-effects model where at least two studies had sufficient data for that variable.
RESULTS
Searches identified 4223 articles of which 18 studies were included with a total 44 patients undergoing cardiac surgery. Within these studies, 12 (66.7%) reported populations undergoing coronary artery bypass graft (CABG) surgery, three (16.7%) aortic valve replacements (AVR) and three (16.7%) aortic dissection repairs. Overall mean postoperative length of ICU stay was 3.39 (95% confidence interval (CI): 0.38, 6.39) and mean postoperative length of hospital stay was 17.88 (95% CI: 14.57, 21.19).
CONCLUSION
This systematic review and meta-analysis investigated studies of limited quality which characterized cardiac surgery in COVID-19 positive patients and demonstrates that these patients have poor outcomes. Further issues to be explored are effects of COVID-19 on decision-making in cardiac surgery, and effects of COVID-19 on the cardiovascular system at a cellular level.

Meta-Analysis Review
The relationship between body mass index and short term postoperative outcomes in patients undergoing potentially curative surgery for colorectal cancer: A systematic review and meta-analysis.
BACKGROUND
The prevalence of obesity has increased worldwide over the last few decades, and is a well-recognized risk factor for colorectal cancer. Surgical site infection is the most frequent complication following surgery for colorectal cancer, and the main cause of postoperative morbidity. The aim of the present systematic review and meta-analysis was to examine the relationship between increasing BMI and postoperative surgical site infection following surgery for colorectal cancer.
METHODS
A systemic literature search was conducted using Medline, PubMed, Embase (Ovid) and Web of Science databases from inception to the end of August 2016. Studies examining the relationship between obesity and surgical site infection following surgery for colorectal cancer were included. Analysis of the data was performed using Review Manager version 5.3(The Nordic Cochrane Centre, The Cochrane Collaboration, Copen-hagen, Denmark,) RESULTS: In this meta-analysis, a total of 9535 patients from 16 studies were included. BMI <30 vs ≥30kg/m was used to examine the association of obesity and surgical site infection in patients from Western countries. The estimated pooled OR demonstrated that obesity increased the risk of surgical site infection by approximately 100% (OR=2.13; 95% CI 1.66-2.72, p<0.001).BMI <25 vs ≥25kg/m was used to examine the association of obesity and surgical site infection from Asian countries. The estimated pooled OR demonstrated that obesity increased the risk of surgical site infection by approximately 60% (OR=1.63; 95% CI 1.29-2.06, p<0.001). There was little evidence of publication bias in the meta-analysis.
CONCLUSION
From this systematic review and meta-analysis there was good evidence that obesity was associated with a significantly higher risk of developing surgical site infection following surgery for colorectal cancer in both ethnic groups. The magnitude of the effect warrants further investigation.

Meta-Analysis Review
Background and Objectives: While laparoscopic appendectomy is standardized, techniques for appendiceal stump closure and mesoappendix division remain variable. Novel vessel sealing techniques are increasingly utilized ubiquitously. We sought to systematically summarize all relevant data and to define the current evidence on the safety and utility of energy devices for clipless−sutureless laparoscopic appendectomy in this systematic review and meta-analysis. Materials and Methods: This review was conducted following the PRISMA guidelines. PubMed, Embase, Scopus, and Web of Science were systematically searched. Inclusion criteria included studies with laparoscopic appendectomy for appendicitis. The intervention included patients undergoing division of mesoappendix and/or securing of the appendicular base using diathermy (Monopolar or Bipolar or LigaSure Sealing Device) or Harmonic Scalpel (Group A) compared to patients undergoing division of mesoappendix and/or securing of the appendicular base using endoclip or Hem-o-lok or ligature (Group B). The methodological quality of the included studies was assessed using the Downs and Black scale. The outcomes of surgical site infection (SSI) or intra-abdominal collection, postoperative ileus, average operative duration, and length of hospital stay (LHS) were compared. Results: Six comparative studies were included; three were retrospective, two were prospective, and one was ambispective. Meta-analysis revealed a shorter operative duration in Group A with respect to appendicular base ligation (MD −12.34, 95% CI −16.57 to −8.11, p < 0.00001) and mesoappendix division (MD −8.06, 95% CI −14.03 to −2.09, p = 0.008). The pooled risk ratios showed no difference in SSI between groups. Additionally, no difference was observed in LHS. The risk of postoperative ileus was higher in group B regarding mesoappendix division (RR 0.56, 95% CI 0.34 to 0.93, p = 0.02), but no difference was found concerning appendicular base ligation. The included studies showed a moderate-to-high risk of bias. Conclusions: Clipless−sutureless laparoscopic appendectomy is safe and fast. Postoperative ileus seems less common with energy devices for mesoappendix division. However, the studies included have a moderate-to-high risk of bias. Further studies addressing the individual devices with surgeons of similar levels are needed.
