Review
BACKGROUND
Increasing obesity prevalence and development of bariatric surgery have led to the development of skin re-draping techniques. Several contouring techniques have been described for treating the circumferential excess of the lower trunk.
MATERIALS AND METHODS
We performed a systematic review to summarize surgical indications, operative techniques, peri-operative management (nutritional supplementation, antibiotic prophylaxis, thrombo-prophylaxis), outcomes, complications, patient satisfaction, and impact on quality of life of circumferential contouring of the lower trunk procedures. A systematic review, based on the PRISMA criteria, was conducted using the Pubmed and Cochrane databases.
RESULTS
The review included 42 articles and 1748 operated patients. Two studies only were graded as level of evidence II; the others were graded as levels III to V. The most frequently reported indication was massive weight loss. All the described techniques derived either from belt lipectomy or lower bodylift. Belt lipectomy resulted in a posterior scar situated at the waistline and allowed a better correction of hip back rolls, whereas lower bodylift was more effective on buttock and lateral thigh ptosis. The most reported complication was wound dehiscence. Patient satisfaction and quality of life scores were high in all studies.
CONCLUSIONS
This review included a majority of low-level evidence studies that limit extrapolability of the results. Future randomized prospective studies may generate stronger evidence, with a standardization of surgical indications and operative techniques.

Review
BACKGROUND
Bacterial infections occurring during labour, childbirth, and the puerperium may be associated with considerable maternal and perinatal morbidity and mortality. Antibiotic prophylaxis might reduce wound infection incidence after an episiotomy, particularly in situations associated with a higher risk of postpartum perineal infection, such as midline episiotomy, extension of the incision, or in settings where the baseline risk of infection after vaginal birth is high. However, available evidence is unclear concerning the role of prophylactic antibiotics in preventing infections after an episiotomy.
OBJECTIVES
To assess whether routine antibiotic prophylaxis before or immediately after incision or repair of episiotomy for women with an uncomplicated vaginal birth, compared with either placebo or no antibiotic prophylaxis, prevents maternal infectious morbidities and improves outcomes.
SEARCH METHODS
We searched the Cochrane Pregnancy and Childbirth's Trials Register, LILACS, ClinicalTrials.gov, and the WHO International Clinical Trials Registry Platform (ICTRP) on 24 July 2017, and screened reference lists of retrieved studies.
SELECTION CRITERIA
We considered randomised controlled trials, quasi-randomised trials, and cluster-randomised trials that compared the use of routine antibiotic prophylaxis for incision or repair of an episiotomy for women with otherwise normal vaginal births, compared with either placebo or no antibiotic prophylaxis.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed trials for inclusion and risk of bias, extracted data, and checked them for accuracy. We only found one quasi-randomised trial that met the inclusion criteria and was included in the analysis, therefore, we did not perform a meta-analysis.
MAIN RESULTS
We included one quasi-RCT (with data from 73 women) in the review. The trial, which was conducted in a public hospital in Brazil, compared oral chloramphenicol 500 mg four times daily for 72 hours after episiotomy repair (N = 34) and no treatment (N = 39). We assessed most of the domains at high risk of bias because women were randomised according to even and odd numbers, allocation concealment was based on protocol number, there was no treatment or placebo administered in the control group, we were unclear about the blinding of outcome assessments, and outcomes were incompletely reported. We considered the other domains to be at low risk of bias. We downgraded the quality of the evidence for very serious design limitations (related to lack of random sequence generation, allocation concealment, and blinding) and imprecision of effect estimates (small sample sizes and wide confidence intervals (CI) of effect estimates).We found very low-quality evidence, from one trial of 73 women, that there was no clear indication that prophylactic antibiotics reduced the incidence of episiotomy wound dehiscence with infection (risk ratio (RR) 0.13, 95% CI 0.01 to 2.28), or without infection (RR 0.82, 95% CI 0.29 to 2.34). No cases of other puerperal infections (e.g. endometritis) were reported in either the antibiotic or control group.The trial did not report on any of the secondary outcomes of interest for this review, including severe maternal infectious morbidity, discomfort or pain at the episiotomy wound site, sexual function postpartum, adverse effects of antibiotics, costs of care, women's satisfaction with care, and individual antimicrobial resistance.
AUTHORS' CONCLUSIONS
There was insufficient evidence to assess the clinical benefits or harms of routine antibiotic prophylaxis for episiotomy repair after normal birth. The only trial included in this review had several methodological limitations, with very serious limitations in design, and imprecision of effect estimates. In addition, the trial tested an antibiotic with limited application in current clinical practice. There is a need for a careful and rigorous assessment of the comparative benefits and harms of prophylactic antibiotics on infection morbidity after episiotomy, in well-designed randomised controlled trials, using common antibiotics and regimens in current obstetric practice.

Review
BACKGROUND
Postpartum maternal infection is still a common problem worldwide, mainly due to obstetric risk factors. The use of prophylactic antibiotic at operative vaginal delivery (OVD), taking it as a standalone risk factor, has been controversial. The purpose of this review was to rigorously evaluate the association of OVD with postpartum infection and shed light on such highly controversial issue.
METHODS
A computer-based literature search was done mainly in the databases of PUBMED, HINARI health research, and the Cochrane library. Systematic review and meta-analysis were done by including 14 articles published between 1990 and August 2019.
RESULTS
The average absolute risk of postpartum infection at OVD from seven large cohort studies was 1%. Few studies showed a weak association of OVD with postpartum infection without being adjusted to perineal wound, but the pooled meta-analysis showed statistically significant association with non-OVD. In the included randomized trial, 97% of the study participants had perineal wound for whom repairs were performed; the risks of maternal infection and perineal wound breakdown were comparable, and maternal infections other than perineal wound infection did not show significant difference between prophylactic antibiotic and placebo groups. The majority of included studies demonstrated a strong association of postpartum infection and perineal wound dehiscence with episiotomy and perineal tear.
CONCLUSION
Both the relative and absolute risks of postpartum infection at OVD are extremely low unless accompanied by episiotomy and 3/4t degree perineal tear. From previous studies, there is no substantial evidence to use prophylactic antibiotic at OVD, but episiotomy and perineal tear.

Meta-Analysis
OBJECTIVES
Previous studies showed the effectiveness of negative pressure wound therapy (NPWT) in preventing surgical site infections (SSIs), but current guidelines do not recommend its routine use for surgical wounds. The aim was to compare the effectiveness and safety of NPWT with standard surgical dressing or conventional therapy for preventing SSIs.
METHODS
Pubmed, Embase and the Cochrane Library were systematically searched on 10 April 2019. Also, we searched clinicaltrials.gov and references of relevant studies. Eligibility criteria were randomized controlled trials (RCTs) and adult surgical patients were included. The effectiveness of NPWT versus standard surgical dressing or conventional therapy was investigated. Relative risks (RRs) and mean differences (MDs) with 95% confidence intervals (CIs) were used to estimate the pooled effect of dichotomous outcomes and continuous outcomes respectively. The primary outcome was surgical site infections. The quality of included studies and the certainty of the evidence were assessed using the risk of bias tool and the GRADE approach.
RESULTS
A total of 45 RCTs with 6624 surgical patients were included. NPWT reduced SSIs (RR 0.58; 95% CI 0.49-0.69) and wound dehiscence(17 RCTs; RR 0.80; 95% CI 0.65-1.00). NPWT did not increase the risk of hematoma (9 RCTs; RR 0.91; 95% CI 0.40-2.07) and hospital readmission(9 RCTs; RR 0.77; 95% CI 0.52-1.12) or prolong length of hospital stay(15 RCTs; MD -0.38; 95% CI, -0.78 to 0.02). NPWT significantly increased the risk of all adverse event-related outcomes (10 RCTs; RR 3.21; 95% CI, 1.17-8.78). The level of certainty was identified as low for the primary outcome and very low for all the secondary outcomes.
CONCLUSIONS
Compared with standard wound care, NPWT may reduce the risk of SSIs. We are uncertain whether NPWT reduces or increases the risk of wound dehiscence, haematoma, hospital readmission and all adverse event-related outcomes or if it shortens or prolongs length of hospital stay.

Meta-Analysis Review
OBJECTIVE
To determine in patients with localized primary melanoma of the trunk or extremities the optimal excision margin that achieves the highest disease-free survival and overall survival and the lowest local recurrence rate.
DATA SOURCES
Trials comparing 2 different excision margins were identified by searching MEDLINE from 1966 to May 2002 using the term "melanoma," subheading "surgery," and limiting the search to human studies and randomized controlled trials (RCTs). Additional studies were found using the MeSH term "surgical procedures, operative," combining with "melanoma," and limiting to human studies. We searched EMBASE and the Cochrane Library in May 2002 using similar terminology. No language restriction was applied.
STUDY SELECTION
We selected studies for the overview using the following inclusion criteria: design--an RCT with wide excision versus narrower excision (margin width was not specified a priori); population--adult patients (> 18 yr) with cutaneous melanoma of the trunk or extremities without evidence of metastasis; intervention--surgical excision of the primary melanoma; and outcomes--at least 1 of overall survival, disease-free survival, local recurrence, wound complications and necessity for skin grafting.
DATA EXTRACTION
Information was abstracted for each outcome reported in the studies, and results were pooled by consensus. Statistical analysis was performed using RevMan 4.1 (The Cochrane Collaboration) software program. Relative risk and risk difference were reported with 95% confidence intervals. The number needed to harm was calculated for the need for skin grafting by taking the inverse of the risk difference.
DATA SYNTHESIS
Three trials and their follow-up studies met the inclusion criteria and included 2087 adults with localized cutaneous melanoma of the trunk or extremities. No statistically significant differences were found between wide surgical excision (margins ranging from 3-5 cm) and narrower surgical excision (margins ranging from 1-2 cm) with respect to mortality, disease-free survival or local recurrence rate.
CONCLUSIONS
Surgical excision margins no more than 2 cm around a melanoma of the trunk or extremities are adequate; overall survival, disease-free survival and recurrence rate are not adversely affected compared with a wider excision. There is more data to support a 2-cm margin than a 1-cm margin as the minimum margin of excision. Surgical margins should be no less than 1 cm around the primary melanoma.

Meta-Analysis
An ongoing debate concerns the need for routine placement of prophylactic intra-abdominal drains following kidney transplantation. <br/><br/>Aim: We conducted a systematic review and meta-analysis to determine whether such an approach brings any advantages in the prevention of perirenal transplant fluid collection, surgical site infection, lymphocele, hematoma, urinoma, wound dehiscence, graft loss, and need for reoperation. <br/><br/>Methods: We conducted a random-effects meta-analysis of non-randomized studies of intervention comparing drained and drain-free adult renal graft recipients regarding perirenal transplant fluid collection and other wound complications. ROBINS-I tool and funnel plot asymmetry analysis were used to assess the risk of bias. <br/><br/>Results: Five studies at moderate to critical risk of bias were included. A total of 2094 renal graft recipients were evaluated. Our analysis revealed no significant differences between drained and drain-free patients regarding perirenal transplant fluid collection (pooled odds ratio [OR], 0.77; 95% confidence interval [CI], 0.28-2.17; I 2 = 72%), surgical site infection (OR, 1.64; 95% CI, 0.11-24.88; I 2 = 80%), lymphocele (OR, 0.61; 95% CI, 0.02-15.27; I 2 = 0%), hematoma (OR, 0.71; 95% CI, 0.12-3.99; I 2 = 71%), and wound dehiscence (OR, 0.75; 95% CI, 0.21-2.70; I 2 = 0%). There was insufficient data concerning urinoma, graft loss, and need for reoperation. <br/><br/>Conclusions: The available evidence is weak. Our findings show that the use of intra-abdominal drains after kidney transplantation seems to have neither beneficial nor harmful effects on perirenal transplant fluid collection and other wound complications. The present study does not support the routine placement of surgical drains after kidney transplantation. <i>In this systematic review and meta-analysis we summarize the most up-to-date evidence for and against the routine use of intra-abdominal drain following renal transplantation.</i>.

Comparison of Single-Incision Scrotal Orchiopexy and Traditional Two-Incision Inguinal Orchiopexy for Primary Palpable Undescended Testis in Children: A Systematic Review and Meta-Analysis.
PURPOSE
To compare the safety, efficacy, and cosmetic results of single-incision scrotal orchiopexy (SISO) and traditional two-incision inguinal orchiopexy (TTIO) for primary palpable undescended testes (PUDTs) in children.
MATERIALS AND METHODS
A systematic literature search of all relevant studies published on PubMed, Embase, Medline, Cochrane Library, Web of Science database, and Wanfang data until July 2021 was conducted. The operative time, hospitalization duration, conversion rate, wound infection or dehiscence, scrotal hematoma or swelling, testicular atrophy, reascent, hernia or hydrocele, analgesics needs, and cosmetic results were compared between SISO and TTIO using the Mantel-Haenszel or inverse-variance method.
RESULTS
A total of 17 studies involving 2,627 children (1,362 SISOs and 1,265 TTIOs) were included in the final analysis. The conversion rate of SISO was 3.6%. The SISO approach had a statistically significant shorter operative time than the TTIO approach for PUDT (weighted mean difference-11.96, 95% confidence interval -14.33 to -9.59, I = 79%, < 0.00001) and a shorter hospital stay (weighted mean difference-1.05, 95% confidence interval -2.07 to -0.03, = 0.04). SISO needed fewer analgesics and had better cosmetic results than TTIO. SISO had a similar total, short-term, or long-term complication rate with TTIO.
CONCLUSION
Compared with TTIO, SISO has the advantages of shorter operative time, shorter hospitalization duration, less postoperative pain, and better cosmetic appealing results. SISO is a safe, effective, promising, and potential minimal invasive surgical approach for PUDT. SISO is an alternative to TTIO in selected cryptorchid patients, especially for lower positioned ones.

Meta-Analysis
IMPORTANCE
Surgical site infections (SSIs) are common after laparotomy wounds and are associated with a significant economic burden. The use of negative pressure wound therapy (NPWT) has recently been broadened to closed surgical incisions.
OBJECTIVE
To evaluate the association of prophylactic NPWT with SSI rates in closed laparotomy incisions performed for general and colorectal surgery in elective and emergency settings.
DATA SOURCES
The PubMed, Embase, Cochrane Central Register of Controlled Trials, and Google Scholar databases were searched without language restrictions for relevant articles from inception until December 2017. The latest search was performed on December 31, 2017. The bibliographies of retrieved studies were further screened for potential additional studies.
STUDY SELECTION
Randomized clinical trials and nonrandomized studies were included. Unpublished reports were excluded, as were studies that examined NPWT (or standard nonpressure) dressings only without a comparator group. Studies that evaluated the use of NPWT in open abdominal incisions were also excluded. Disagreement was resolved by discussion, and if the question remained unsettled, the opinion of the senior author was sought. A total of 198 citations were identified, and 189 were excluded.
DATA EXTRACTION AND SYNTHESIS
This meta-analysis was conducted according to PRISMA guidelines. Data were independently extracted by 2 authors. A random-effects model was used for statistical analysis.
MAIN OUTCOMES AND MEASURES
The primary outcome measure was SSI, and secondary outcomes included seroma and wound dehiscence rates. These outcomes were chosen before data collection.
RESULTS
Nine unique studies (3 randomized trials and 2 prospective and 4 retrospective studies) capturing 1266 unique patients were included. Of these, 1187 patients with 1189 incisions were included in the final analysis (52.3% male among 7 studies reporting data on sex; mean [SD] age, 52 [15] years among 8 studies reporting data on age). Significant clinical and methodologic heterogeneity existed among studies. On random-effects analysis, NPWT was associated with a significantly lower rate of SSI compared with standard dressings (pooled odds ratio [OR], 0.25; 95% CI, 0.12-0.52; P < .001). However, no difference in rates of seroma (pooled OR, 0.38; 95% CI, 0.12-1.23; P = .11) or wound dehiscence (pooled OR, 2.03; 95% CI, 0.61-6.78; P = .25) was found. On sensitivity analysis, focusing solely on colorectal procedures, NPWT significantly reduced SSI rates (pooled OR, 0.16; 95% CI, 0.07-0.36; P < .001).
CONCLUSIONS AND RELEVANCE
Application of NPWT on closed laparotomy wounds in general and colorectal surgery is associated with reduced SSI rates but similar rates of seroma and wound dehiscence compared with conventional nonpressure dressings.

Review
BACKGROUND
Prepectoral breast reconstruction has once again appealed, which attributes to the introduction of acellular dermal matrices (ADMs) and mesh. Postmastectomy radiation therapy (PMRT), meanwhile, is crucial in the whole course of treatment for breast cancer patients with lymph node-positive. The impact of PMRT on outcomes after prepectoral breast reconstruction has not been clearly defined to date. This study aimed to compare the impact of PMRT on outcomes after prepectoral vs. subpectoral breast reconstruction.
METHODS
A comprehensive research on databases including PubMed, Embase, and Cochrane libraries was performed to retrieve literature pertaining to prepectoral breast reconstruction from database inception to October 2021. All included studies evaluated the impact of PMRT on outcomes after breast reconstruction. Only studies comparing patients who underwent prepectoral breast reconstruction with a control group who underwent subpectoral breast reconstruction were included. Data were analyzed using RevMan version 5.2.
RESULTS
A total of 4 studies were included in the meta-analysis, with a total of 394 breasts. In the setting of postmastectomy radiation therapy, 164 breasts were reconstructed with a prepectoral approach, whereas the remaining 230 breasts underwent subpectoral reconstruction. Overall, outcomes between PBR and SBR was no statistical significance in the overall complications (OR: 1.30, 95% CI: 0.35-4.85), infection (OR: 1.62, 95% CI: 0.90-2.91), seroma (OR: 1.60, 95% CI: 0.48-5.27), skin flap necrosis (OR: 0.77, 95% CI: 0.17-3.45), hematoma (OR: 0.38, 95% CI: 0.10-1.41), wound dehiscence (OR: 0.82, 95% CI: 0.36-1.85). But, included studies lacked data about the patient quality of life and satisfaction with the outcome of the reconstructed breast.
CONCLUSIONS
In the setting of postmastectomy radiation therapy, prepectoral breast reconstruction is a safe and effective option.

Review
Obesity is one of the primary public health problems faced by children. The increased incidence of obesity in the pediatric population poses significant challenges during and after surgical procedures. This systematic review and meta-analysis aimed to understand to what extent obesity is to surgical complications in pediatric patients. A systematic database search of PubMed, Web of Science, Scopus, and Science Direct was performed in June 2023. According to the inclusion and exclusion criteria, two evaluators independently conducted literature screening, data extraction, and quality evaluation of the retrieved literature. The Newcastle-Ottawa Scale score was used for quality evaluation, and a meta-analysis was performed using Review Manager software 5.4.1. A total of 1,170 relevant articles were initially identified, and 20 articles were finally included for data extraction and meta-analysis. The results of the meta-analysis showed that compared with normal-weight individuals, obese pediatric patients had a higher risk of developing surgical site infection (SSI) (relative risk (RR) = 1.63; 95% confidence interval (CI) = 1.33-2.00), wound dehiscence (RR = 2.01; 95% CI = 1.24-3.23), and underwent procedures that were 11.32 minutes longer (95% CI = 5.36-17.29). There were no differences in bleeding requiring transfusion, deep venous thromboembolism, postoperative abscess rate, and length of stay. Obese pediatric patients have a higher risk of SSI and dehiscence, along with a longer operative time. The established risks in obese adults undergoing surgery suggest a similar risk for obese pediatric patients. The findings of this study hold significant implications for clinical practice, suggesting the potential for additional measures to prevent surgical complications in children.
