Meta-Analysis
BACKGROUND
Sarcopenia refers to the progressive age- or pathology-associated loss of skeletal muscle. When measured radiologically as reduced muscle mass, sarcopenia has been shown to independently predict morbidity and mortality after elective abdominal surgery. However, the European Working Group on Sarcopenia in Older People (EWGSOP) recently updated their sarcopenia definition, emphasizing both low muscle 'strength' and 'mass'. The aim of this systematic review and meta-analysis was to determine the prognostic impact of this updated consensus definition of sarcopenia after elective abdominal surgery.
METHODS
MEDLINE, Embase, Scopus, and Cochrane Central Register of Controlled Trials (CENTRAL) databases were systematically searched for studies comparing prognostic outcomes between sarcopenic versus non-sarcopenic adults after elective abdominal surgery from inception to 15 June 2022. The primary outcomes were postoperative morbidity and mortality. Sensitivity analyses adjusting for confounding patient factors were also performed. Methodological quality assessment of studies was performed independently by two authors using the QUality in Prognosis Studies (QUIPS) tool.
RESULTS
Twenty articles with 5421 patients (1059 sarcopenic and 4362 non-sarcopenic) were included. Sarcopenic patients were at significantly greater risk of incurring postoperative complications, despite adjusted multivariate analysis (adjusted OR 1.56, 95 per cent c.i. 1.39 to 1.76). Sarcopenic patients also had significantly higher rates of in-hospital (OR 7.62, 95 per cent c.i. 2.86 to 20.34), 30-day (OR 3.84, 95 per cent c.i. 1.27 to 11.64), and 90-day (OR 3.73, 95 per cent c.i. 1.19 to 11.70) mortality. Sarcopenia was an independent risk factor for poorer overall survival in multivariate Cox regression analysis (adjusted HR 1.28, 95 per cent c.i. 1.13 to 1.44).
CONCLUSION
Consensus-defined sarcopenia provides important prognostic information after elective abdominal surgery and can be appropriately measured in the preoperative setting. Development of targeted exercise-based interventions that minimize sarcopenia may improve outcomes for patients who are undergoing elective abdominal surgery.

Meta-Analysis Review
BACKGROUND
Our objective is to compare the early outcomes associated with passive (gravity) drainage (PG) and active drainage (AD) after surgery.
METHODS
Studies published until April 28, 2022 were retrieved from the PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, Web of Science databases.
RESULTS
Nine studies with 14,169 patients were identified. Two groups had the same intra-abdominal infection rate (RR: 0.55; = 0.13); In subgroup analysis of pancreaticoduodenectomy, active drainage had no significant effect on postoperative pancreatic fistula (POPF) rate (RR: 1.21; = 0.26) and clinically relevant POPF (CR-POPF) (RR: 1.05; = 0.72); Active drainage was not associated with lower percutaneous drainage rate (RR: 1.00; = 0.96), incidence of sepsis (RR: 1.00; = 0.99) and overall morbidity (RR: 1.02; = 0.73). Both groups had the same POPF rate (RR: 1.20; = 0.18) and CR-POPF rate (RR: 1.20; = 0.18) after distal pancreatectomy. There was no difference between two groups on the day of drain removal after pancreaticoduodenectomy (Mean difference: -0.16; = 0.81) and liver surgery (Mean difference: 0.03; = 0.99).
CONCLUSIONS
Active drainage is not superior to passive drainage and both drainage methods can be considered.

Meta-Analysis
BACKGROUND
Incisional hernia (IH) is the main complication after laparotomy. In an attempt to reduce this complication, mesh techniques and studies in which the closure technique is modified have been proposed. Both types are characterized by comparison with the closure described as standard or conventional: 1 × 1, mass, and continuous closure. For this study, modified closure techniques (MCTs) were considered as those techniques in which an extra suture is placed (reinforced tension line (RTL), retention), the closure point is modified in distance (small bites) or shape (CLDC, Smead Jones, interrupted, Cardiff point) and which aim to reduce these complications. The objective of this network meta-analysis (NMA) was to evaluate the effectiveness of MCTs for reducing the incidence of IH and abdominal wound dehiscence (AWD) to provide objective support for their recommendation.
METHODS
An NMA was performed according to the PRISMA-NMA guidelines. The primary objective was to determine the incidence of IH and AWD, and the secondary objective was to determine the incidence of postoperative complications. Only published clinical trials were included. The risk of bias was analyzed, and the random-effects model was used to determine statistical significance.
RESULTS
Twelve studies comparing 3540 patients were included. The incidence of HI was lower in RTL, retention suture, and small bites, these techniques showed statistical differences with pooled ORs (95% CI) of 0.28 (0.09-0.83), 0.28 (0.13-0.62), and 0.44 (0.31-0.62), respectively. Associated complications, including hematoma, seroma, and postoperative pain, could not be analyzed; however, MCTs did not increase the risk of surgical site infection.
CONCLUSION
Small bites, RTL, and retention sutures decreased the prevalence of IH. RTL and retention suture decreased the prevalence of AWD. RTL was the best technique as it reduced both complications (IH and AWD) and had the best SUCRA and P-scores, and the number needed to treat (NNT) for net effect was 3.
REGISTRATION
This study was prospectively registered in the PROSPERO database under registration number CRD42021231107.

Meta-Analysis Review
PURPOSE
Surgical repair of large hernia defects requires detailed pre-operative planning, particularly in cases with loss of domain. This situation often hampers mid-line reconstruction, even after component separation, when the size of the hernia is disproportional to the volume of the abdominal area. In this case, other strategies may be needed to place the viscera back into the abdominal cavity after reducing the hernia sac. The administration of botulinum toxin prior to the surgical procedure has been indicated as an adjunct for more complex cases. This results in stretching of the lateral musculature of the abdomen, allowing midline approximation. In addition, the application of botulinum toxin alone has been investigated as a means of downstaging in the management of ventral hernias, thereby precluding component separation and enabling primary closure of the midline by placement of mesh within the retromuscular space using the Rives Stoppa technique.
METHODS
Systematic review of the literature for observational studies involving patients undergoing pre-operative application of botulinum toxin for ventral hernia repair was conducted according to the PRISMA guidelines.
RESULTS
Advance of the lateral musculature of the abdomen by an average of 4.11 cm with low heterogeneity, as well as low rates of surgical site infection (SSI), surgical site occurrences (SSO) and recurrence, was shown.
CONCLUSION
Pre-operative application of botulinum toxin for ventral hernia repair promoted an increase in the length of the lateral musculature of the abdomen which can help improve the outcomes of morbidity and recurrence.

BACKGROUND
Staging laparoscopy for gastric cancer is recommended to assess the tumor's locoregional extension and exclude peritoneal disease. As there is no consensus on optimizing the procedure's diagnostic accuracy, we aimed to systematically review the literature on operative techniques, followed by peritoneal lavage fluid assessment in gastric cancer patients. Specifically, we sought to indicate the most common characteristics of the procedure and cytological evaluation.
METHODS
This study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The protocol for this systematic review was registered on PROSPERO database (CRD: 42022306746). On September 2022, a search was carried out using Embase, Medline ALL, Cochrane Central Register of Controlled Trials, and Web of Science Core Collection.
RESULTS
The search identified 1632 studies on staging laparoscopy and 2190 studies on peritoneal fluid assessment. Some 212 studies were included. Open Hasson was the method of choice in accessing the peritoneal cavity in 65% of the studies, followed by establishing a pneumoperitoneum at 10-12 mmHg in 52% of reports. Most frequently, the patient was positioned supine (70%), while a 30° scope and three ports were used to assess the peritoneal cavity clockwise (72%, 77%, and 85%, respectively). Right and left upper abdomen quadrants were the predominant area of laparoscopic exploration (both 65%), followed by the primary tumor region (54%), liver and pelvis (both 30%), and small bowel and spleen (19% and 17%, respectively). Regions of peritoneal lavage and aspiration were limited to the pelvis (50%), followed by right and left upper abdomen quadrants (37.5% and 50%, respectively). No studies compared different methods of operative techniques or analysis of ascites/fluid.
CONCLUSIONS
This study indicates a high heterogeneity in the technique of staging laparoscopy and peritoneal fluid assessment in gastric cancer patients. Further research and initiatives to reach a consensus on the standardization of the procedure are warranted.

Review
AIM
To compare the efficacy and safety of synthetic and biological meshes in ventral hernia repair (VHR) and abdominal wall reconstruction (AWR).
METHODS
We screened all clinical trials that reported the application of synthetic and biological meshes in VHR and AWR using Medline, Web of Science, and Embase (Ovid). Only comparative studies with similar baselines such as age, sex, body mass index, degree of wound contamination, and hernia defects between the intervention and control groups were included. Effect sizes with 95% confidence were pooled using a random- or fixed-effects model based on the size of heterogeneity. A sensitivity analysis was performed to test the stability of the results.
RESULTS
Ten studies with 1305 participants were included. Biological meshes were associated with significantly higher recurrence rate (OR, 2.09; 95% CI 1.42-3.08; I = 50%), surgical site infection (OR, 1.47; 95% CI 1.10-1.97; I = 30%), higher re-admission rate (OR, 1.51; 95% CI 1.05-2.17; I = 50%), and longer length of hospital stay (SMD, 0.37; 95% CI 0.10-0.65; I = 72%). Similar surgical site occurrence, re-operation rate, and mesh explantation rate were observed among biological and synthetic meshes. Biological meshes have no difference in recurrence rate as compared to synthetic meshes, between the clean-contaminated, and contamination-infected fields (OR, 1.41; 95% CI 0.41-4.87 vs 3.00; 95% CI 1.07-8.46; P = 0.36).
CONCLUSION
Synthetic meshes are a safe alternative to biological meshes for VHR and AWR. Considering the high cost of biological meshes, synthetic meshes are more appropriate for the VHR and AWR.

Review
BACKGROUND
As advanced maternal age and bariatric procedures have become more common, the number of women seeking pregnancy after having abdominoplasty has increased. This has traditionally been a relative contraindication and counselled against, though there are little data in the literature regarding the potential effects to mother and baby.
METHODS
A systematic review of Medline and Embase databases was performed to identify cases of pregnancy occurring after abdominoplasty. Data were extracted and analysed for presentation.
RESULTS
17 studies encompassing 237 patients met inclusion. Mean age was 33.08 years. Mean parity prior to first pregnancy after abdominoplasty 2.13. Previous bariatric surgery was reported in 31.75%. Body contouring procedure was abdominoplasty (94.51%), body lift (3.80%) and other (1.69%). Rectus plication was performed in 89.74%, where reported. Mean time between abdominoplasty and pregnancy was 3.75 years. Method of delivery was Caesarean section in 43.63%, and vaginal delivery in 56.37%. Mean gestational age at delivery was 38.90 weeks. Preterm delivery (<37 weeks) was reported in 9.85%, and low birthweight (<2500 g) was reported in 7.22%. Diagnoses or complications were documented in 14 studies (136 patients). These were grouped as foetal/neonatal (n = 21), maternal (n = 104) or abdominal wall/aesthetic (n = 96); and are detailed within. There were no neonatal or maternal mortalities in any study. A lower-than-expected spinal anaesthetic block was stated in 3 cases. Mean follow-up was 8.5 months.
CONCLUSION
Pregnancy should not be contraindicated after abdominoplasty. The data presented allow clinicians to have an evidence-based discussion and provide information for shared decision-making.

Review
BACKGROUND
A groin hernia is a collective name for inguinal and femoral hernias, which can present acutely with incarceration or strangulation of the hernia sac content, requiring emergency treatment. Timely repair of emergency groin hernias is crucial due to the risk of reduced blood supply and thus damage to the bowel, but the optimal surgical approach is unclear. While mesh repair is the standard treatment for elective hernia surgery, using mesh for emergency groin hernia repair remains controversial due to the risk of surgical site infection.
OBJECTIVES
To assess the benefits and harms of mesh compared with non-mesh in emergency groin hernia repair in adult patients with an inguinal or femoral hernia.
SEARCH METHODS
On 5 August 2022, we searched the following databases: CENTRAL, MEDLINE Ovid, and Embase Ovid, as well as two trial registers for ongoing and completed trials. Additionally, we performed forward and backward citation searches for the included trials and relevant review articles. We searched without any language or publication restrictions.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) comparing mesh with non-mesh repair in emergency groin hernia surgery in adults. We included any mesh and any non-mesh repairs. All studies fulfilling the study, participant, and intervention criteria were included irrespective of reported outcomes.
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methodology. We presented dichotomous data as risk ratios (RR) with 95% confidence intervals (CI). We based missing data analysis on best- and worst-case scenarios. For outcomes with sufficiently low heterogeneity, we performed meta-analyses using the random-effects model. We analysed subgroups when feasible, including the degree of contamination. We used RoB 2 for risk of bias assessment, and summarised the certainty of evidence using GRADE.
MAIN RESULTS
We included 15 trials randomising 1241 participants undergoing emergency groin hernia surgery with either mesh (626 participants) or non-mesh hernia repair (615 participants). The studies were conducted in China, the Middle East, and South Asia. Most patients were men, and most participants had an inguinal hernia (41 participants had femoral hernias). The mean/median age in the mesh group ranged from 35 to 70 years, and from 41 to 69 years in the non-mesh group. All studies were performed in a hospital emergency setting (tertiary care) and lasted for 11 to 139 months, with a median study duration of 31 months. The majority of the studies only included participants with clean to clean-contaminated surgical fields. For all outcomes, we considered the certainty of the evidence to be very low, mainly downgraded due to high risk of bias (due to deviations from intended intervention and missing outcome data), indirectness, and imprecision. Mesh hernia repair may have no effect on or slightly increase the risk of 30-day surgical site infections (RR 1.66, 95% CI 0.96 to 2.88; I² = 21%; 2 studies, 454 participants) when compared with non-mesh hernia repair, but the evidence is very uncertain. The evidence is also very uncertain about the effect of mesh hernia repair compared with non-mesh hernia repair on 30-day mortality (RR 1.38, 95% CI 0.58 to 3.28; 1 study, 208 participants). In summary, the results showed 70 more (from 5 fewer to 200 more) surgical site infections and 29 more (from 32 fewer to 175 more) deaths within 30 days of mesh hernia repair per 1000 participants compared with non-mesh hernia repair. The evidence is very uncertain about 90-day surgical site infections after mesh versus non-mesh hernia repair (RR 1.00, 95% CI 0.15 to 6.64; 1 study, 60 participants; very low-certainty evidence). No 30-day recurrences were recorded, and mesh hernia repair may not reduce recurrence within one year (RR 0.19, 95% CI 0.04 to 1.03; I² = 0%; 2 studies, 104 participants; very low-certainty evidence). Within 30 days of hernia repair, no meshes were removed from clean to clean-contaminated fields, but 6.7% of meshes (1 study, 208 participants) were removed from contaminated to dirty surgical fields. Among the four studies reporting 90-day mesh removal, no events occurred. We were not able to identify any studies reporting complications classified according to the Clavien-Dindo Classification or reoperation for complications within 30 days of repair.
AUTHORS' CONCLUSIONS
Our results show that in terms of 30-day surgical site infections, 30-day mortality, and hernia recurrence within one year, the evidence for the use of mesh hernia repair compared with non-mesh hernia repair in emergency groin hernia surgery is very uncertain. Unfortunately, firm conclusions cannot be drawn due to very low-certainty evidence and meta-analyses based on small-sized and low-quality studies. There is a need for future high-quality RCTs or high-quality registry-based studies if RCTs are unfeasible.

Meta-Analysis
OBJECTIVE
To compare the safety and efficacy of robotic-assisted retroperitoneal lymph node dissection (RA-RPLND) versus non-robotic retroperitoneal lymph node dissection in testicular cancer.
METHODS
The statistical analysis software used Stata 17. The weighted mean difference (WMD) represents the continuous variable, and the dichotomous variable chooses the odds ratio, and calculates the 95% CI. This systematic review and cumulative meta-analysis was performed according to PRISMA criteria, and AMSTAR guidelines (assessing the methodological quality of systematic reviews). The Embase, PubMed, Cochrane Library, Web of Science, and Scopus databases were searched. The upper limit of the search time frame was February 2023, and no lower limit was set.
RESULTS
Seven studies involving 862 patients. Compared with open retroperitoneal lymph node dissection, RA-RPLND appears to have a shorter length of stay [WMD=-1.21, 95% CI (-1.66, -0.76), P <0.05], less estimated blood loss [WMD=-0.69, 95% CI (-1.07, -0.32), P <0.05], and lower overall complications [odds ratio=0.45, 95% CI (0.28, 0.73), P <0.05]. RA-RPLND appears to have more lymph node yields than laparoscopic retroperitoneal lymph node dissection [WMD=5.73, 95% CI (1.06, 10.40), P <0.05]. However, robotic versus open/laparoscopic retroperitoneal lymph node dissection had similar results in operation time, lymph node positivity rate, recurrence during follow-up, and postoperative ejaculation disorders.
CONCLUSION
RA-RPLND appears to be safe and effective for testicular cancer, but longer follow-up and more studies are needed to confirm this.

Meta-Analysis Review
To evaluate the oncological outcomes and safety of primary retroperitoneal lymph node dissection (RPLND) in patients with clinical stage (CS) II seminomatous testicular germ cell tumor (TGCT). A literature search using PubMed, Scopus, and Cochrane Library was conducted on July 2023 to identify relevant studies according to the Preferred Reporting Items for Systematic Review and Meta Analysis (PRISMA) guidelines. The pooled recurrence rate and treatment-related complications were calculated using a random effects model. Overall 8 studies published between 1997 and 2023 including a total of 355 patients were selected for systematic review and meta-analysis with the overall median follow-up of 38 months. The overall and infield recurrence rate were 0.14 (95% CI: 0.08-0.22) and 0.04 (95% CI: 0.00-0.11), respectively. The overall pooled rate of ≥ Clavien Dindo grade III complications was 0.04 (95% CI: 0.01-0.10); there was no significant heterogeneity (I^2 = 35.10%, P = 0.19). Antegrade ejaculation was preserved with the overall pooled rate of 0.98 (95% CI: 0.95-1.00); there was no significant heterogeneity on Chi-square and I2 tests (I^2 = 0.00%, P = 0.58). Primary RPLND is a safe and effective treatment option for patients with CS II seminomatous TGCT resulting highly promising cure rates combined with low treatment-associated adverse events, at medium-term follow-up. However, owing to the lack of comparative studies to the current standard of care and the limited follow-up, individual decision must be made with the informed patient in a shared decision process together with a multidisciplinary team.
