OBJECTIVE
This systematic review aims to evaluate current choice in practice and outcomes of biomaterials used in patch repair of congenital diaphragmatic hernia (CDH).
BACKGROUND
Multiple biomaterials, both novel and combinations of pre-existing materials are employed in patch repair of large size CDH.
METHODS
Literature search was performed across Embase, Medline, Scopus, and Web of Science. Publications that explicitly reported patch repair, material used and recurrences following CDH repair were selected.
RESULTS
Sixty-three papers were included, presenting data on 4598 patients of which 1811 (39.4%) were managed using 19 types of patches. Goretex® (GTX) (n=1259) was the most frequently employed patch followed by Surgisis® (n=164), Dualmesh® (n=114), Marlex®/GTX® (n=56), Tutoplast dura® (n=40), Dacron® (n=34), Dacron®/GTX® (n=32), Permacol® (n=24), Teflon® (n=24), Surgisis®/GTX® (n=15), Sauvage® Filamentous Fabric (n=13), Marlex® (n=9), Alloderm® (n=8), Silastic® (n=4), Collagen coated Vicryl® mesh (CCVM) (n=1), Mersilene® (n=1), and MatriStem® (n=1) Biomaterials were further subgrouped as: Synthetic non-resorbable (SNOR) (n=1458), Natural-resorbable (NR) (n=249), Combined natural and synthetic non-resorbable (NSNOR) (n=103), and Combined natural and synthetic resorbable (NSR) (n=1). Overall recurrence rate for patch repair was 16.8% (n=305). For patch types with n>20, recurrence rate was lowest in GTX/Marlex (3.6%), followed by Teflon (4.2%), Dacron (5.6%), GTX (13.8%), Permacol (16.0%), Tutoplast Dura (17.5%), Dualmesh (20.2%), SIS/GTX (26.7%), SIS (36.6%), and Dacron/GTX (37.5%).When analysed by biomaterial groups, recurrence was highest in NSR (100%), followed by NR (32.9%), NSNOR (17.5) and SNOR the least (14.0%).
CONCLUSION
In this cohort, over one-third of CDH were closed using patches. To date, 19 patch types/variations have been employed for CDH closure. GTX is the most popular, employed in 70% of patients; however excluding smaller cohorts (n<20) GTX/Marlex is associated with the lowest recurrence rate (3.6%). SNOR was the material type least associated with recurrence while NSR experienced recurrence in every instance.

PURPOSE
To review possible risk factors for permanent delayed-onset, progressive sensorineural hearing loss (SNHL) in the paediatric population to recommend follow-up protocols for early detection.
METHODS
PRISMA-compliant systematic review was performed, including observational studies on the paediatric population up to 16 years old who have passed the newborn hearing screening programme (NHSP), investigating the development of late-onset, progressive SNHL. Electronic searches were performed through Medline, Embase, Cochrane, and Emcare.
RESULTS
37 studies were included. 21 showed an association between late-onset SNHL and congenital cytomegalovirus (cCMV) infection (age at hearing loss diagnosis 0.75 to 204 months, mean 45.6 ± 43.9), while 16 between late-onset SNHL and other congenital or perinatal factors, namely Neonatal Intensive Care Unit (NICU) stay, prematurity, neonatal respiratory failure, mechanical ventilation, extracorporeal membrane oxygenation (ECMO) support, hypocapnia, hypoxia, alkalosis, seizure activity, congenital diaphragmatic hernia (CDH), inner ear malformation, and gene mutations (age at hearing loss diagnosis 2.5 to 156 months, mean 38.7 ± 40.7).
CONCLUSIONS
cCMV infection may cause late-onset SNHL, which can be missed on standard NHSP. There is, therefore, evidence to support universal screening programmes to enable detection in even asymptomatic neonates. Ongoing audiological follow-up for all children with cCMV is advisable, to enable timely treatment. In the paediatric population presenting conditions such as NICU stay > 5 days, prematurity ≤ 34 weeks gestation, severe neonatal respiratory failure, mechanical ventilation, ECMO support, and CDH surgery, an audiological follow-up from 3 months of age up to at least 3-4 years of age, and at least annually, should be recommended.

Meta-Analysis Review
BACKGROUND
Improved outcomes with the use of non-absorbable mesh (NAM) for inguinal hernia repairs led to its rapid adoption for hiatal hernia (HH) repairs; however, feared complications occurred, and the trend shifted toward using absorbable mesh (AM). We aimed to analyze the literature assessing objective HH recurrence rates after primary laparoscopic cruroplasty with or without the use of different mesh types.
METHODS
A systematic literature review with both pairwise and time-organized proportion meta-analyses of articles published between January 1993 and September 2022 was performed using the MEDLINE, EMBASE, and Taylor & Francis databases to identify relevant studies comparing groups undergoing cruroplasty with suture repair (SR) alone, AM, NAM, or partially absorbable mesh (PAM). Studies documenting an objective follow-up ≥ 6 months were included. The primary outcome was the HH recurrence rate confirmed by barium esophagram or upper GI endoscopy.
RESULTS
A total of 34 studies met the inclusion criteria, including 6 randomized clinical trials, 25 retrospectives studies, and 3 prospective cohort studies. A total of 2170 subjects underwent laparoscopic HH repair and completed an objective follow-up ≥ 6 months after surgery; the objective recurrence rate was 20.8% (99/477) at a mean follow-up of 25.8 ± 16.4 months for the SR group, 20.6% (244/1187) at 28.1 ± 13.8 months for the AM group, 13.7% (65/475) at 30.8 ± 15.3 months for the NAM group, and 0% (0/31) at 32.5 ± 13.5 months for the PAM group. However, the pairwise meta-analysis revealed that overall mesh use was not superior to SR in preventing long-term HH recurrence.
CONCLUSION
The use of AM does not appear to reduce HH recurrence compared to SR alone. Although the data favors NAM to decrease objective HH recurrence in the mid-term, the long-term (≥ 48 months) recurrence rate was similar with or without any type of mesh.

BACKGROUND
Symptomatic and large hiatal hernia (HH) is a common disorder requiring surgical management. However, there is a lack of systematic, evidence-based recommendations summarizing recent reviews on surgical treatment of symptomatic HH. Therefore, this systematic review aimed to create evidence mapping on the key technical issues of HH repair based on the highest available evidence.
METHODS
A systematic review identified studies on eight key issues of large symptomatic HH repair. The literature was screened for the highest level of evidence (LE from level 1 to 5) according to the Oxford Center for evidence-based medicine's scale. For each topic, only studies of the highest available level of evidence were considered.
RESULTS
Out of the 28.783 studies matching the keyword algorithm, 47 were considered. The following recommendations could be deduced: minimally invasive surgery is the recommended approach (LE 1a); a complete hernia sac dissection should be considered (LE 3b); extensive division of short gastric vessels cannot be recommended; however, limited dissection of the most upper vessels may be helpful for a floppy fundoplication (LE 1a); vagus nerve should be preserved (LE 3b); a dorso-ventral cruroplasty is recommended (LE 1b); routine fundoplication should be considered to prevent postoperative gastroesophageal reflux (LE 2b); posterior partial fundoplication should be favored over other forms of fundoplication (LE 1a); mesh augmentation is indicated in large HH with paraesophageal involvement (LE 1a).
CONCLUSION
The current evidence mapping is a reasonable instrument based on the best evidence available to guide surgeons in determining optimal symptomatic and large HH repair.

Meta-Analysis
BACKGROUND
Poly-4-hydroxybutyrate (P4HB) is a bioabsorbable mesh with a non-adhesive coating on one side that is being used to reinforce the hiatus during hiatal hernia repair; however, there is limited data regarding its use. The aim of this study was to investigate outcomes after hiatal hernia repair using this mesh at our institution and through a review of the literature.
METHODS
An institutional review board-approved prospective database was retrospectively reviewed for all patients undergoing hiatal hernia repair from April 2018 to December 2022. A systematic review with meta-analysis was conducted to evaluate outcomes using P4HB coated mesh.
RESULTS
In our institutional cohort, there were 230 patients (59 males; 171 females) with a mean follow-up of 20 ± 14.6 months. No mesh-related complications occurred. Hernia recurrence was diagnosed in 11 patients (4.8%) with a median time to recurrence of 16 months. In the systematic review, 4 studies with 221 patients (76 males; 145 females) were included. Median follow-up ranged from 12 to 27 months. Recurrence rate in these studies was reported from 0 to 8.8%, with a total of 12 recurrences identified. Like our institutional cohort, no mesh-related complications were reported. After our recurrences were combined with those from the systematic review, a total of 23 recurrences were included in the meta-analysis. Our meta-analysis revealed a low recurrence rate following hiatal hernia repair with P4HB coated mesh (incidence rate per 100 person-years, 2.82; 95% confidence interval, 1.60, 4.04).
CONCLUSION
P4HB coated mesh is safe and effective for hiatal hernia repairs.

A Morgagni hernia is a congenital diaphragmatic hernia that is rarely diagnosed in adults, and the technique for its repair has not yet been standardized. This review will give an overview of the different laparoscopic methods reported by other authors, highlighting the key points indicating a good repair to help standardize the technique. A systematic review of the available articles on PubMed was conducted according to PRISMA 2020 by two authors independently in May 2022. Only articles written in English were included. A total of 180 case reports of laparoscopic Morgagni's hernia repair procedures were found; direct repair was performed in 59 patients, mesh was used in 119 patients, and mesh was not used in 2 patients. The hernia sac was removed in 71 patients, and the defect was closed before mesh placement in 49 patients. Nonabsorbable, dual or biologic mesh was used. The mean operative time was 92.65 min for direct repair and 84.11 min for mesh repair. One recurrence was reported in the direct repair series. The optimal method of repair has not yet been identified. The laparoscopic approach is associated to fewer complications and facilitates a faster recovery than the open approach. Several manoeuvres have been reported to help surgeons, who are not trained in laparoscopic knotting, perform extracorporeal knotting. Mesh should be placed when tension is too high after a direct repair or when primary closure cannot be achieved.

World Journal of Clinical Cases Sep 2023Diaphragmatic hernia (DH) is extremely rarely described during pregnancy. Due to the rarity, there is no diagnostic or treatment algorithm for DH in pregnancy.
BACKGROUND
Diaphragmatic hernia (DH) is extremely rarely described during pregnancy. Due to the rarity, there is no diagnostic or treatment algorithm for DH in pregnancy.
AIM
To summarize and define the most appropriate diagnostic methods and therapeutic options for DH in pregnancy based on scarce literature.
METHODS
Literature search of English-, German-, Spanish-, and Italian-language articles were performed using PubMed (1946-2021), PubMed Central (1900-2021), and Google Scholar. The PRISMA protocol was followed. The search terms included: Maternal diaphragmatic hernia, congenital hernia, pregnancy, cardiovascular collapse, mediastinal shift, abdominal pain in pregnancy, hyperemesis, diaphragmatic rupture during labor, puerperium, hernie diaphragmatique maternelle, hernia diafragmática congenital. Additional studies were identified by reviewing reference lists of retrieved studies. Demographic, imaging, surgical, and obstetric data were obtained.
RESULTS
One hundred and fifty-eight cases were collected. The average maternal age increased across observed periods. The proportion of congenital hernias increased, while the other types appeared stationary. Most DHs were left-sided (83.8%). The median number of herniated organs declined across observed periods. A working diagnosis was correct in 50%. DH type did not correlate to maternal or neonatal outcomes. Laparoscopic access increased while thoracotomy varied across periods. Presentation of less than 3 days carried a significant risk of strangulation in pregnancy.
CONCLUSION
The clinical presentation of DH is easily confused with common chest conditions, delaying the diagnosis, and increasing maternal and fetal mortality. Symptomatic DH should be included in the differential diagnosis of pregnant women with abdominal pain associated with dyspnea and chest pain, especially when followed by collapse. Early diagnosis and immediate intervention lead to excellent maternal and fetal outcomes. A proposed algorithm helps manage pregnant women with maternal DH. Strangulated DH requires an emergent operation, while delivery should be based on obstetric indications.

Ventilating a pediatric patient during thoracoscopy is challenging. Few studies have highlighted the impact of capnothorax in children by measuring regional cerebral oxygen saturation (rcSO) with near infrared spectroscopy. In this systematic review, we aimed to summarize the data from relevant studies and assess whether thoracoscopy in children is associated with intraoperative pathological cerebral desaturation. The authors systematically searched four databases for relevant studies on the measurement of rcSO during pediatric thoracoscopic procedures. The primary outcome was the proportion of patients with pathological desaturation, that is, >20% decline in the intraoperative rcSO. Risk of bias among the included studies was estimated using the Newcastle-Ottawa scale. The systematic search resulted in 776 articles, of which 7 studies were included in the analysis. In total, 88 patients (99 procedures) with an age ranging from 0 days to 8.1 years were included. Of these, 43 (49%) patients were neonates. The included cohort had esophageal atresia and tracheoesophageal fistula ( = 26), long-gap esophageal atresia ( = 5), congenital diaphragmatic hernia ( = 14), and congenital pulmonary airway malformations and other conditions needing lung resection ( = 43). Of the total 99 procedures, pathological desaturation was noticed in 13 (13.1%, 95% confidence interval 7.2-21.4) of them. Upon quality assessment, most of the studies were weaker in the selection and comparability domains. In this review, pathological cerebral desaturation was noticed in 13.1% of the pediatric thoracoscopic procedures. However, due to limited methodological quality of the included studies, further randomized multicentric studies comparing rcSO in open versus thoracoscopic surgeries are needed to derive definitive conclusions.

In 1990, Gorlin et al. described four types of craniofacial duplications: (1) single mouth with duplication of the maxillary arch; (2) supernumerary mouth laterally placed with rudimentary segments; (3) single mouth with replication of the mandibular segments; and (4) true facial duplication, namely diprosopus. We describe a newborn born with wide-spaced eyes, a very broad nose, and two separate mouths. Workup revealed the absence of the corpus callosum and the presence of a brain midline lipoma, wide sutures, and a Chiari I malformation with cerebellar herniation. We conducted a systematic review of the literature and compared all the cases described as diprosopus. In 96% of these, the central nervous system is affected, with anencephaly being the most commonly associated abnormality. Other associated anomalies include cardiac malformations (86%), cleft palate (63%), diaphragmatic hernia (13%), and disorder of sex development (DSD) (13%). Although the facial features are those that first strike the eye, the almost obligate presence of cerebral malformations suggests a disruptive event in the cephalic pole of the forming embryo. No major monogenic contribution has been recognized today for this type of malformation.

Meta-Analysis
Outcomes of conventional mechanical ventilation (CMV) and high-frequency oscillatory ventilation (HFOV) in patients with congenital diaphragmatic hernia (CDH) were compared through a systematic review and meta-analysis. Outcome measures included mortality and incidence of chronic lung disease (CLD). Odds ratio (OR) and 95% confidence interval (95%CI) were evaluated. Subgroup analyses were performed according to the strategy for applying HFOV in CDH patients. Group A: CMV was initially applied in all CDH patients, and HFOV was applied in unstable patients. Group B: chronologically analyzed. (CMV and HFOV era) Group C: CMV or HFOV was used as the initial MV. Of the 2199 abstracts screened, 15 full-text articles were analyzed. Regarding mortality, 16.7% (365/2180) and 32.8% (456/1389) patients died in CMV and HFOV, respectively (OR, 2.53; 95%CI 2.12-3.01). Subgroup analyses showed significantly worse, better, and equivalent mortality for HFOV than that for CMV in group A, B, and C, respectively. CLD occurred in 32.4% (399/1230) and 49.3% (369/749) patients in CMV and HFOV, respectively (OR, 2.37; 95%CI 1.93-2.90). The evidence from the literature is poor. Mortality and the incidence of CLD appear worse after HFOV in children with CDH. Cautious interpretation is needed due to the heterogeneity of each study.
