Review
INTRODUCTION
Reinforcement of crural closure with synthetic resorbable mesh has been proposed to decrease recurrence rates after hiatal hernia repair, but continues to be controversial. This systematic review aims to evaluate the safety, efficacy, and intermediate-term results of using biosynthetic mesh to augment the hiatus.
METHODS
The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed throughout this systematic review. The Risk of Bias in Non-Randomized Studies of Interventions and Risk of Bias in Randomized Trials tools were used to perform qualitative assessment of all studies included in this review. Recommendations were then summarized for the following pre-defined key items: protocol, research question, search strategy, study eligibility, data extraction, study design, risk of bias, publication bias, and statistical analysis.
RESULTS
The systematic literature search found 520 articles, 101 of which were duplicates and 355 articles were determined to be unrelated to our study and excluded. The full text of the remaining 64 articles was thoroughly assessed. A total of 18 articles (1846 patients) were ultimately included for this review, describing hiatal hernia repair using three different biosynthetic meshes-BIO-A, Phasix ST, and polyglactin mesh. Mean operative time varied from 127 to 223 min. Mean follow up varied from 12 to 54 months. There were no mesh erosions or explants. One mesh-related complication of stenosis requiring reoperation was reported with BIO-A. Studies showed significant improvement in symptom and quality-of-life scores, as well as satisfaction with surgery. Recurrence was reported as radiologic or clinical recurrence. Overall, recurrence rate varied from 0.9 to 25%.
CONCLUSION
The use of biosynthetic mesh is safe and effective for hiatal hernia repair with low complications rates and high symptom resolution. The reported recurrence rates are highly variable due to significant heterogeneity in defining and evaluating recurrences. Further randomized controlled trials with larger samples and long-term follow-up should be performed to better analyze outcomes and recurrence rates.

Review
BACKGROUND
Post-hepatectomy diaphragmatic hernia is the second most common cause of acquired diaphragmatic hernia. This study aims to review the literature on this complication's incidence, treatment and prognosis.
METHODS
Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we systematically searched PubMed for all studies related to acquired diaphragmatic hernias after hepatectomy.
RESULTS
We included 28 studies in our final analysis, comprising 11,368 hepatectomies. The incidence of post-hepatectomy diaphragmatic hernia was 0.75% (n = 86). The most frequent type of hepatectomy performed was right hepatectomy (79%, n = 68), and the indications for liver resection were a liver donation for living donor transplantation (n = 40), malignant liver tumors (n = 13), and benign tumors (n = 11). The mean onset between liver resection and the diagnosis of diaphragmatic hernia was 25.7 months (range, 1-72 months), and the hernia was located on the right diaphragm in 77 patients (89.5%). Pain was the most common presenting symptom (n = 52, 60.4%), while six patients were asymptomatic (6.9%). Primary repair by direct suture was the most frequently performed technique (88.3%, n = 76). Six patients experienced recurrence (6.9%), and three died before diaphragmatic hernia repair (3.5%).
CONCLUSION
Diaphragmatic hernia is a rare complication occurring mainly after right liver resection. Repair should be performed once detected, given the not-negligible associated mortality in the emergency setting.

BACKGROUND
Neonatal care is commonly regionalised, meaning specialist services are only available at certain units. Consequently, infants with surgical conditions needing specialist care who are born in non-surgical centres require postnatal transfer. Best practice models advocate for colocated maternity and surgical services as the place of birth for infants with antenatally diagnosed congenital conditions to avoid postnatal transfers. We conducted a systematic review to explore the association between location of birth and short-term outcomes of babies with gastroschisis, congenital diaphragmatic hernia (CDH) and oesophageal atresia with or without tracheo-oesophageal fistula (TOF/OA).
METHODS
We searched MEDLINE, CINAHL, Web of Science and SCOPUS databases for studies from high income countries comparing outcomes for infants with gastroschisis, CDH or TOF/OA based on their place of delivery. Outcomes of interest included mortality, length of stay, age at first feed, comorbidities and duration of parenteral nutrition. We assessed study quality using the Newcastle-Ottawa Scale. We present a narrative synthesis of our findings.
RESULTS
Nineteen cohort studies compared outcomes of babies with one of gastroschisis, CDH or TOF/OA. Heterogeneity across the studies precluded meta-analysis. Eight studies carried out case-mix adjustments. Overall, we found conflicting evidence. There is limited evidence to suggest that birth in a maternity unit with a colocated surgical centre was associated with a reduction in mortality for CDH and decreased length of stay for gastroschisis.
CONCLUSIONS
There is little evidence to suggest that delivery in colocated maternity-surgical services may be associated with shortened length of stay and reduced mortality. Our findings are limited by significant heterogeneity, potential for bias and paucity of strong evidence. This supports the need for further research to investigate the impact of birth location on outcomes for babies with congenital surgical conditions and inform future design of neonatal care systems.

Meta-Analysis
BACKGROUND
Fetoscopic endoluminal tracheal occlusion (FETO) has been shown to improve survival of infants with congenital diaphragmatic hernia (CDH). However, there are concerns that FETO may lead to tracheomegaly, tracheomalacia and related complications.
METHODS
A systematic review was conducted to estimate the prevalence of symptomatic tracheal complications in infants who underwent FETO for CDH. Presence of one or more of the following was considered as tracheal complication: tracheomalacia, stenosis, laceration or tracheomegaly with symptoms such as stridor, effort-induced barking cough, recurrent chest infections or the need for tracheostomy, tracheal suturing, or stenting. Isolated tracheomegaly on imaging or routine bronchoscopy without clinical symptoms was not considered as tracheal morbidity. Statistical analysis was performed using the metaprop command on Stata V.16.0.
RESULTS
A total of 10 studies (449 infants) were included (6 retrospective cohort, 2 prospective cohort and 2 randomised controlled trials). There were 228 infants who survived to discharge. Prevalence rates of tracheal complications in infants born alive were 6% (95% CI 2% to 12%) and 12% (95% CI 4% to 22%) in those who survived to discharge. The spectrum of severity ranged from relatively mild symptoms such as effort-induced barking cough to the need for tracheostomy/tracheal stenting.
CONCLUSION
A significant proportion of FETO survivors have symptomatic tracheal morbidities of varying severity. Units that are planning to adopt FETO for managing CDH should consider ongoing surveillance of survivors to enable early identification of upper airway issues. Inventing FETO devices that minimise tracheal injury is needed.

Review
INTRODUCTION
A congenital intrathoracic kidney (ITK) is a rare anomaly that is recognized to have four causes: renal ectopia with an intact diaphragm, diaphragmatic eventration, diaphragmatic hernia, and traumatic diaphragmatic rupture. We report a case of a prenatal-diagnosed ITK related to a congenital diaphragmatic hernia (CDH) and conducted a systematic review of all cases of the prenatal diagnosis of this association.
CASE PRESENTATION
A fetal ultrasound scan at 22 gestational weeks showed left CDH and ITK, hyperechoic left lung parenchyma, and mediastinal shift. The fetal echocardiography and karyotype were normal. Magnetic resonance imaging at 30 gestational weeks confirmed the ultrasound suspicion of left CDH in association with bowel and left kidney herniation. The fetal growth, amniotic fluid, and Doppler indices remained within the normal range over time. The woman delivered the newborn via an at-term spontaneous vaginal delivery. The newborn was stabilized and underwent non-urgent surgical correction; the postoperative course was uneventful.
CONCLUSIONS
CDH is the rarest cause of ITK; we found only eleven cases describing this association. The mean gestational age at diagnosis was 29 ± 4 weeks and 4 days. There were seven cases of right and four cases of left CDH. There were associated anomalies in only three fetuses. All women delivered live babies, the herniated kidneys showed no functional damage after their surgical correction, and the prognosis was favorable after surgical repair. The prenatal diagnosis and counseling of this condition are important in planning adequate prenatal and postnatal management in order to improve neonatal outcomes.

Meta-Analysis Review
The number of robotic hiatal hernia repairs (RHHR) is increasing. However, the superiority of this minimally invasive approach remains controversial. The aim of this study was to evaluate the available literature reporting on outcomes of RHHR compared with laparoscopic hiatal hernia repair (LHHR) in adult patients. The design of this systematic review was developed using the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Web of Science, PubMed, the Cochrane Library, and ClinicalTrials.gov databases were searched. Identified publications were reviewed independently by two authors. High heterogeneity was further explored through sensitivity analysis. The primary endpoint was the development of postoperative complications. Secondary endpoints included operation time, intraoperative complications, 30 day readmission rates and length of stay. The analysis was performed using Stata 17.0 software. A total of 7 studies totaling 10078 patients met the inclusion criteria. Five studies included postoperative complications. The postoperative complications rate was 4.25% (302/7111) in the LHHR group, and 3.49% (38/1088) in the RHHR group. Postoperative complications significantly decreased after RHHR compared with LHHR (OR 0.52; 95% CI 0.36 to 0.75, P = 0.000). Three studies involving 2176 patients reported length of hospital stay. In the three studies, the mean Length of hospital stay was 3.2 days in the RHHR group, and 4.2 days in the LHHR group. Length of hospital stay was decreased by a mean of 0.68 days for RHHR compared with LHHR (WMD, - 0.68 days; 95% CI - 1.32 to - 0.03, P = 0.02). There was no significant difference between the RHHR group and the LHHR group regarding operative time, intraoperative complications, and 30 day readmission (P > 0.05). Our research shows that RHHR may be the better option, as the approach decreases postoperative complications and length of hospital stay.

Meta-Analysis
OBJECTIVES
To evaluate the correlation between stomach position (SP) grading and postnatal outcomes in fetuses with isolated left-sided congenital diaphragmatic hernias (CDHs).
METHODS
A literature search was conducted using the PubMed, Embase, and Cochrane Library databases. The corresponding 95% confidence intervals (CIs) were used to assess the differences in the odds of mortality according to the SP graded as level 0 to level 3. To evaluate the reliability of our results, a sensitivity analysis was also conducted.
RESULTS
Nine papers with a total of 542 fetuses with isolated left-sided CDH were included. Congenital diaphragmatic hernia pregnancies complicated by an intrathoracic stomach had higher odds of neonatal mortality when compared with intraabdominal stomach (odds ratio [OR] 2.86; 95% CI 1.38-5.94). Four papers with SP grading from level 0 to level 3 were included in a subgroup analysis. Stomach position at level 1 and level 2 had lower odds of neonatal mortality when separately compared to level 3 (OR 0.12; 95% CI 0.04-0.33) and (OR 0.30; 95% CI 0.16-0.54). Stomach position at level 1 had lower odds of neonatal mortality when compared with level 2 + 3 (OR 0.25; 95% CI 0.09-0.66).
CONCLUSION
Survival of fetuses with isolated left-sided CDH is correlated with the SP.

Meta-Analysis
BACKGROUND
Prognostication of mortality and decision to offer extracorporeal membrane oxygenation (ECMO) treatment in infants with congenital diaphragmatic hernia (CDH) can inform clinical management.
OBJECTIVE
To summarise the prognostic value of echocardiography in infants with CDH.
METHODS
Electronic databases Ovid MEDLINE, Embase, Scopus, CINAHL, the Cochrane Library and conference proceedings up to July 2022 were searched. Studies evaluating the prognostic performance of echocardiographic parameters in newborn infants were included. Risk of bias and applicability were assessed using the Quality Assessment of Prognostic Studies tool. We used a random-effect model for meta-analysis to compute mean differences (MDs) for continuous outcomes and relative risk (RR) for binary outcomes with 95% CIs. Our primary outcome was mortality; secondary outcomes were need for ECMO, duration of ventilation, length of stay, and need for oxygen and/or inhaled nitric oxide.
RESULTS
Twenty-six studies were included that were of acceptable methodological quality. Increased diameters of the right and left pulmonary arteries at birth (mm), MD 0.95 (95% CI 0.45 and 1.46) and MD 0.79 (95% CI 0.58 to 0.99), respectively) were associated with survival. Left ventricular (LV) dysfunction, RR 2.40, (95% CI 1.98 to 2.91), right ventricular (RV) dysfunction, RR 1.83 (95% CI 1.29 to 2.60) and severe pulmonary hypertension (PH), RR 1.69, (95% CI 1.53 to 1.86) were associated with mortality. Left and RV dysfunctions, RR 3.30 (95% CI 2.19 to 4.98) and RR 2.16 (95% CI 1.85 to 2.52), respectively, significantly predicted decision to offer ECMO treatment. Limitations are lack of consensus on what parameter is optimal and standardisation of echo assessments.
CONCLUSIONS
LV and RV dysfunctions, PH and pulmonary artery diameter are useful prognostic factors among patients with CDH.

Meta-Analysis Review
This systematic review and meta-analysis aimed to review the optimal timing of delivery at term for neonates with prenatally diagnosed congenital diaphragmatic hernia (CDH). We reviewed the literature up to December 19, 2022 using MEDLINE and the Cochrane Library databases. The inclusion criteria were original articles, comparative studies of CDH neonates delivered at an early term (37-38 weeks of gestation) and at full term (39 weeks of gestation or later), and comparative studies investigating outcomes of CDH neonates. Six studies met the inclusion criteria, including 985 neonates delivered at an early term and 629 delivered at full term. The cumulative rate of survival to discharge showed no significant difference between CDH neonates delivered at an early term (395/515; 76.7%) or at full term (345/467; 73.9%) (risk ratio [RR] 1.01; 95% confidence interval [CI], 0.89-1.16; p = 0.85). Furthermore, the number of neonates requiring oxygen therapy at discharge was not significantly different between CDH neonates delivered at an early term (32/370; 8.6%) and at full term (14/154; 9.1%) (RR, 0.99; 95% CI, 0.36-2.70; p = 0.99). Therefore, the optimal timing of delivery at term for neonates with CDH remains unclear.

Review
BACKGROUND
In both clinical practice and residency training, the use of robotic platforms in surgery is becoming more common. The aim of this study was to perform a systematic review of the perioperative outcomes of robotic and laparoscopic paraesophageal hernia (PEH) repair.
METHODS
The PRISMA statement guidelines were used to perform this systematic review. We conducted a database search which included Ovid MEDLINE(R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, and Daily, Ovid EMBASE, Ovid Cochrane Central Register of Controlled Trials, Ovid Cochrane Database of Systematic Reviews, and Scopus. There were 384 articles discovered in the initial search using various keywords. From those 384 articles, after duplicates were removed and publications were eliminated based on eligibility criteria, 7 publications were then chosen for analysis. Risk of bias was assessed using Cochrane Risk of Bias Assessment Tool. Narrative synthesis of results has been provided.
RESULTS
When compared to standard laparoscopic approaches, robotic surgery for large PEHs may offer benefits in terms of decreased conversion rate and shorter hospital stay. Some studies found a decrease in need for esophageal lengthening procedures and fewer long-term recurrences. The perioperative complication rate is similar between the two techniques in most studies; however, one large study of nearly 170,000 patients in the early years of robotics adoption demonstrated a higher rate of esophageal perforation and respiratory failure in the robotic group (2.2% increase in absolute risk). Cost is another disadvantage of robotic repair when compared to laparoscopic repair. Our study is limited by the non-randomized and retrospective nature of the studies.
CONCLUSIONS
More studies into recurrence rates and long-term complications are needed to determine the efficacy of robotic versus laparoscopic PEHs repair.
