Meta-Analysis
Alcoholic chlorhexidine skin preparation or triclosan-coated sutures to reduce surgical site infection: a systematic review and meta-analysis of high-quality randomised controlled trials.
BACKGROUND
WHO and the UK's National Institute for Health and Care Excellence recommend alcoholic chlorhexidine skin preparation and triclosan-coated sutures to prevent surgical site infections (SSIs). Existing meta-analyses that include studies at high risk of bias, combined with the recent publication of large, randomised trials, justify an updated meta-analysis of high-quality randomised controlled trials (RCTs). We aimed to test the rates of SSI according to skin preparation solutions (ie, alcoholic chlorhexidine vs aqueous povidone-iodine) and types of sutures (ie, coated vs uncoated).
METHODS
In this systematic review and meta-analysis, we searched MEDLINE, Embase, Pubmed, and Cochrane Library databases, with no language restrictions, to identify high-quality RCTs testing either alcoholic chlorhexidine skin preparation (vs aqueous povidone-iodine) or triclosan-coated sutures (vs uncoated sutures), or both, published from database inception to Sept 1, 2021. Patients who received clean-contaminated, contaminated, or dirty surgery were included. We predefined the characteristics of a high-quality trial through an expert consensus process to develop an enhanced Cochrane risk of bias-2 tool specifically for RCTs with a primary outcome of SSI. Data were extracted from published reports. Meta-analysis was performed using a random-effects model and heterogeneity was assessed using the I statistic. This systematic review and meta-analysis was prospectively registered in PROSPERO, CRD42021267220.
FINDINGS
Of 942 studies identified, 933 were excluded. Four high-quality RCTs (n=7467 patients) were included that tested alcoholic chlorhexidine. No significant difference in SSI rates was noted between alcoholic chlorhexidine and aqueous povidone-iodine (17·9% [667 of 3723 patients] vs 19·8% [740 of 3744 patients]; odds ratio 0·84 [95% CI 0·65-1·06]; p=0·21, I=53·1%). Five high-quality RCTs were included that tested triclosan-coated sutures (n=8619 patients), with no significant difference noted between triclosan-coated and uncoated sutures (16·8% [733 of 4360 patients] vs 18·4% [784 of 4259 patients]; OR 0·90 [95% CI 0·74-1·09]; p=0·29, I=36·4%).
INTERPRETATION
Contrary to previous meta-analyses, this study did not show a benefit from either alcoholic chlorhexidine skin preparation or triclosan-coated sutures, both of which are more expensive than other readily available alternatives. Global and national guidance should be reconsidered to remove recommendations for their routine use.

Meta-Analysis
OBJECTIVE
In this systematic review and meta-analysis the authors aimed to directly compare open surgical and endoscope-assisted techniques for the treatment of sagittal craniosynostosis, focusing on the outcomes of blood loss, transfusion rate, length of stay, operating time, complication rate, cost, and cosmetic outcome.
METHODS
A literature search was performed in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Relevant articles were identified from 3 electronic databases (MEDLINE, EMBASE, and CENTRAL [Cochrane Central Register of Controlled Trials]) from their inception to August 2017. The quality of methodology and bias risk were assessed using the Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies. Effect estimates between groups were calculated as standardized mean differences with 95% CIs. Random and fixed effects models were used to estimate the overall effect.
RESULTS
Of 316 screened records, 10 met the inclusion criteria, of which 3 were included in the meta-analysis. These studies reported on 303 patients treated endoscopically and 385 patients treated with open surgery. Endoscopic surgery was associated with lower estimated blood loss (p < 0.001), shorter length of stay (p < 0.001), and shorter operating time (p < 0.001). From the literature review of the 10 studies, transfusion rates for endoscopic procedures were consistently lower, with significant differences in 4 of 6 studies; the cost was lower, with differences ranging from $11,603 to $31,744 in 3 of 3 studies; and the cosmetic outcomes were equivocal (p > 0.05) in 3 of 3 studies. Finally, endoscopic techniques demonstrated complication rates similar to or lower than those of open surgery in 8 of 8 studies.
CONCLUSIONS
Endoscopic procedures are associated with lower estimated blood loss, operating time, and days in hospital. Future long-term prospective registries may establish advantages with respect to complications and cost, with equivalent cosmetic outcomes. Larger studies evaluating patient- or parent-reported satisfaction and optimal timing of intervention as well as heterogeneity in outcomes are indicated.

BACKGROUND
Craniosynostosis is a condition characterized by the premature fusion of 2 or more skull bones. Craniosynostosis of the lambdoid suture is one of the rarest forms, accounting for 1-4% of all craniosynostoses. Documented cases are separated into simple (single suture), complex (bilateral), and associated with adjacent synostoses ("Mercedes Benz" Pattern) or syndromes (i.e., Crouzon, Sathre-Chotzen, Antley-Bixler). This condition can manifest phenotypic deformities and neurological sequelae that can lead to impaired cognitive function if improperly treated or left undiagnosed. Preferred surgical techniques have varied over time but all maintain the common goals of establishing proper head shape and preventing of complications that could contribute to aforementioned sequelae.
SUMMARY
This comprehensive review highlights demographic distributions, embryological development, pathogenesis, clinical presentation, neurological sequelae, radiologic findings, surgical techniques, surgical outcomes, and postoperative considerations of patients with lambdoid craniosynostosis presentation. In addition, a systematic review was conducted to explore the operative management of lambdoid craniosynostosis using PubMed, Embase, and Scopus databases, with 38 articles included after screening. Key Messages: Due to a low volume of published cases, diagnosis and treatment can vary. Large overlap in presentation can occur in patients that display lambdoid craniosynostosis and posterior plagiocephaly, furthering the need for comprehensive analysis. Possessing the knowledge and tools to properly assess patients with lambdoid craniosynostosis will allow for more precise care and improved outcomes.

Review
Research evaluating optimal repair techniques for the reduction of postpartum dyspareunia following obstetric laceration is severely limited. Prevailing guidelines from the American College of Obstetricians and Gynecologists (ACOG) are reliant on data from just nine clinical trials conducted from 1980 to 2012. While the literature on this topic is still limited today, this review aims to synthesize data from past and present studies to ensure that standing clinical recommendations are supported by current literature. A review was conducted per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. Medical Literature Analysis and Retrieval System Online (MEDLINE), Cochrane Library, and Google Scholar were searched. Included articles (1) compared continuous with interrupted repair techniques for subjects with episiotomies and/or second-degree tears, (2) were available in full length, and (3) reported dyspareunia as an outcome variable. Excluded articles were those (1) inclusive of first-, third-, or fourth-degree tears; (2) comparing suture material rather than technique; and (3) not available in English. A meta-analysis was conducted for both acute dyspareunia (<3 months) and chronic dyspareunia (>3 months) utilizing Meta-Essentials Microsoft Excel (Microsoft Corp., Redmond, WA) workbook. Bias was evaluated via Egger regression and Begg and Mazumdar rank correlation tests. Twelve articles met inclusion and exclusion guidelines, seven for acute dyspareunia and eight for chronic dyspareunia. All publications were randomized controlled trials and were inclusive of a total of 4,081 patients. Risk ratios (RRs) and 95% confidence intervals (CIs) were calculated using a random effect model. Analysis revealed no statistically significant difference between continuous and interrupted suture groups for acute dyspareunia (RR: 0.98; 95% CI: 0.89-1.08) or chronic dyspareunia (RR: 0.96; 95% CI: 0.83-1.12). Egger regression test (p-value=0.534) and Begg and Mazumdar rank correlation test (p-value=0.570) indicated minimal publication bias. Compiled data does not indicate a preferential suture technique for the reduction of postpartum dyspareunia. These findings are congruent with the ACOG guidelines; therefore, there is no supporting evidence for ACOG's recommendation of continuous suturing to be overturned.

Ulnar polydactyly is frequently encountered in the newborn nursery and is commonly treated with bedside suture ligation. However, growing concern about the complications associated with suture ligation has led some practitioners to advocate for primary surgical excision instead. Thus, we set out to compare outcomes of suture ligation and surgical excision by systematic appraisal of the literature. Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, a systematic review was performed to identify studies published between 1950 and 2017 that described outcomes of suture ligation, surgical excision, or both. Baseline characteristics, complications, and study quality were extracted for each included article. A total of 900 articles were reviewed, of which 10 studies (8 case series, 2 comparative analyses) met the inclusion criteria. There was considerable heterogeneity among the studies with respect to patient characteristics and reported outcomes. There were 2 retrospective case series of suture ligation that reported no acute complications and a variable proportion of patients with residual remnants or neuromas. Studies evaluating surgical ligation reported no acute or long-term complications, with only 1 case series reporting a small percentage of residual remnants. However, in the largest cohort analysis, the difference in complication rate was reported to be as high as 23.5% for suture ligation compared with 3% for surgical excision. There is a paucity of literature limiting the comparison of suture ligation and surgical excision for ulnar polydactyly. Further studies are required to determine the optimal treatment.

Meta-Analysis
There is no agreed protocol on usage of proper and best suturing material in minimally invasive pyeloplasty. The aim of this meta-analysis was to summarize and analyze current evidence on suturing materials for laparoscopic pyeloplasty. This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Scientific databases (PubMed, Scopus, Web of Science, and EMBASE) were systematically searched for relevant comparative studies on barbed suture (BS) and non-barbed suture (NBS) in minimally invasive pyeloplasty. Five comparative studies met the inclusion criteria and were included in the meta-analysis. Pooling the data demonstrated a significantly shorter operative duration in patients belonging to the BS group versus the NBS group (95% confidence interval [CI] -81.63 to -10.41, = .01), with statistically significant estimated heterogeneity among the included studies ( < .0001). Although the incidence of redo-pyeloplasty was higher in the BS group, the pooled risk ratio (RR) for the need for redo-pyeloplasty in subjects belonging to the BS group versus the NBS group was 6.00 (95% CI 0.78-46.14), demonstrating no statistically significant difference ( = .09). A total of 5 patients developed postoperative complications. The pooled RR for the occurrence of these complication showed no significant difference among the patients belonging to both the groups (95% CI 0.22-6.05, = .88). Minimally invasive pyeloplasty using BS is associated with significantly shorter operative time. The incidence of postoperative complications and requirement of redo-pyeloplasty showed no significant difference among both the treatment groups. Further randomized controlled trials need to be conducted before any definite conclusions are drawn.

Journal of Minimally Invasive Gynecology Jul 2022To compare perioperative outcomes between knotless barbed sutures (KBSs) and conventional smooth sutures for uterine incision closure at cesarean section. (Meta-Analysis)
Meta-Analysis Review
OBJECTIVE
To compare perioperative outcomes between knotless barbed sutures (KBSs) and conventional smooth sutures for uterine incision closure at cesarean section.
DATA SOURCES
MEDLINE, EMBASE, Web of Sciences, Scopus, the Cochrane Library, and ClinicalTrials.gov were searched from the inception of the study to March 2021 without language restriction. The search terms were as follows: ["Stratafix" OR "Quill" OR "V-Loc" OR "Barbs" OR "barbed"] AND ["Cesarean" OR "Caesarean"] AND ["Suturing" OR "Suture" OR "Closure" OR "Repair"]. Moreover, these terms were combined to complete the search.
METHODS OF STUDY SELECTION
Retrospective and randomized peer-reviewed studies comparing the use of KBSs and conventional sutures for uterine incision closure at cesarean section were included. The studies' quality was assessed by the Cochrane risk-of-bias tool. The primary outcome was the time of uterine incision closure in seconds. The secondary outcomes included total operating time (minutes), use of additional hemostatic sutures, rates of blood transfusion, and postoperative complications.
TABULATION, INTEGRATION, AND RESULTS
Of 20 reports identified, 4 representing 3332 women (1473 with KBSs and 1859 with conventional sutures) were eligible. All studies were judged to be at low risk of bias. The uterine incision closure time was significantly lower in the KBS group (mean difference, -110.58; 95% confidence interval [CI], -127.37 to -93.79; p = .001). Furthermore, the rate of use of additional hemostatic sutures was significantly lower in the KBS group (odds ratio, 0.14; 95% CI, 0.07-0.26; p = .001). Total operative time, rates of blood transfusion, febrile morbidity, and length of postoperative stay were comparable. The incidence of postoperative ileus was significantly lower in the KBS group (odds ratio, 0.31; 95% CI, 0.11-0.89; p = .029).
CONCLUSION
The use of KBSs for uterine incision closure was associated with decreased hysterotomy closure time and less frequent need for the placement of additional hemostatic sutures. Other perioperative outcomes were not affected, although the risk of postoperative ileus was reduced.

Meta-Analysis Review
BACKGROUND
Surgical-site infections (SSIs) increase morbidity and mortality in surgical patients and represent an economic burden to healthcare systems. Experiments have shown that triclosan-coated sutures (TCS) are beneficial in the prevention of SSI, although the results from individual randomized controlled trials (RCTs) are inconclusive. A meta-analysis of available RCTs was performed to evaluate the efficacy of TCS in the prevention of SSI.
METHODS
A systematic search of PubMed, Embase, MEDLINE, Web of Science(®), the Cochrane Central Register of Controlled Trials and internet-based trial registries for RCTs comparing the effect of TCS and conventional uncoated sutures on SSIs was conducted until June 2012. The primary outcome investigated was the incidence of SSI. Pooled relative risks with 95 per cent confidence interval (c.i.) were estimated with RevMan 5.1.6.
RESULTS
Seventeen RCTs involving 3720 participants were included. No heterogeneity of statistical significance across studies was observed. TCS showed a significant advantage in reducing the rate of SSI by 30 per cent (relative risk 0·70, 95 per cent c.i. 0·57 to 0·85; P < 0·001). Subgroup analyses revealed consistent results in favour of TCS in adult patients, abdominal procedures, and clean or clean-contaminated surgical wounds.
CONCLUSION
TCS demonstrated a significant beneficial effect in the prevention of SSI after surgery.

Review
INTRODUCTION
The optimal protocol for diagnostic workup of craniosynostosis and the role of specific imaging modalities remain controversial. Skull X-rays and 3-dimensional head CTs are options when physical exam is equivocal but involve ionizing radiation. Ultrasound has emerged as an alternative modality for visualization of cranial sutures, but its use is not widespread.
METHODS
The authors performed a systematic review of the literature on the use of ultrasound for the diagnosis of craniosynostosis.
RESULTS
A total of 12 studies involving 1062 patients were included. Overall, 300 patients (28.2%) were diagnosed with craniosynostosis. A total of 369 (34.7%) patients had their diagnosis (craniosynostosis vs. patent sutures) confirmed with another imaging modality in addition to ultrasound. Among studies, the specificity of ultrasound ranged from 86 to 100%, and the sensitivity from 71 to 100%.
CONCLUSIONS
Ultrasonography of cranial sutures is a feasible and accurate tool for the diagnosis of single-suture craniosynostosis when physical exam findings are insufficient. Although technical aspects of ultrasonography and its interpretation have an associated learning curve, ultrasound can achieve high sensitivity and specificity among patients with suspected craniosynostosis.

Review
PURPOSE
To systematically review meniscal radial tear repair procedures and compare the techniques, outcomes, and complications.
METHODS
Studies were identified through a systematic review of the literature using the Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials, PubMed (1980-2014), Medline (1980-2014), and Embase. Inclusion criteria included a minimum follow-up of 24 months, English language, and publications from 1980 or later. Exclusion criteria were surgical techniques not reporting follow-up, biomechanical studies, cadaver/anatomic studies, and non-radial tear meniscal repair procedures. Meniscal radial repair, meniscal radial tear, meniscal radial tear repair, radial repair and radial tear were used as search terms.
RESULTS
A total of 6 studies (55 patients) met the inclusion criteria. The mean duration of follow-up ranged from 24 to 71 months. Of the 6 studies, 5 reported radial tears to the lateral meniscus and 1 study reported cases of both medial and lateral meniscal radial tears. Two studies reported different inside-out repair techniques, 2 studies reported the use of an all-inside anchor-based repair system, 1 study reported an all-inside repair technique with absorbable sutures, and 1 study reported an inside-out repair with fibrin clots. Average postoperative Lysholm scores were reported in all 6 studies and ranged from 86.9 to 95.6. Average postoperative Tegner activity scores were reported in 4 studies and ranged from 1 to 6.7. The majority of studies concluded that their techniques produced satisfactory healing of the radial tear, without serious subsequent complications.
CONCLUSIONS
Radial repair techniques differed among studies; however, postoperative subjective outcomes revealed patient improvement with repairing radial tears. With the increasing concern of long-term osteoarthritis after meniscectomy, meniscal preservation with repair of radial tears results in improved short-term clinical outcomes; however, long-term outcomes remain unknown.
