Abstract
OBJECTIVE This systematic review aims to evaluate current choices 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 CDHs. METHODS A 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 4595 patients, of which 1803 (39.2%) were managed using 19 types of patches. Goretex® (GTX) (n=1106) was the most frequently employed patch followed by Dualmesh® (n=267), Surgisis® (n=156), 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 nonresorbable (SNOR) (n=1458), natural resorbable (NR) (n=241), combined natural and synthetic nonresorbable (NSNOR) (n=103), and combined natural and synthetic resorbable (NSR) (n=1). The overall recurrence rate for patch repair was 16.6% (n=299). For patch types with n>20, recurrence rate was lowest in GTX/Marlex (3.6%), followed by Teflon (4.2%), Dacron (5.6%), Dualmesh (12.4%), GTX (14.8%), Permacol (16.0%), Tutoplast Dura (17.5%), SIS/GTX (26.7%), SIS (34.6%), and Dacron/GTX (37.5%).When analyzed by biomaterial groups, recurrence was highest in NSR (100%), followed by NR (31.5%), 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 over 60% 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.

Long-Term Results of Diaphragmatic Hernia Repair After Left Ventricular Assist Device Explantation. Ann Thorac Surg 2020; 112:874-879. [PMID: 33186603 DOI: 10.1016/j.athoracsur.2020.10.016] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2020] [Revised: 08/23/2020] [Accepted: 10/07/2020] [Indexed: 12/21/2022]
Abstract
BACKGROUND Diaphragmatic hernias after explantation of a left ventricular assist device (LVAD) at the time of heart transplantation are uncommon, but they can cause morbidity. This study presents midterm to long-term results of diaphragmatic hernia repair in these patients. METHODS A retrospective chart review was performed on a prospectively collected database of all patients who underwent sequential LVAD explantation and heart transplantation at the University of Minnesota (Minneapolis, MN) since 1995. All patients who had a diaphragmatic hernia were included in the study. Patients' demographics, perioperative morbidity, and long-term results were recorded. RESULTS From January 1995 to June 2018, 712 LVADs were placed, and subsequently 293 hearts were transplanted. The incidence of diaphragmatic hernia after heart transplantation was 7.1% (n = 21), with a median time from transplantation to diagnosis of 23 months (interquartile range [IQR], 9 to 39 months). Four patients did not undergo operative repair, and 1 patient was excluded for insufficient data. Sixteen patients underwent diaphragmatic hernia repair (male, 13; female, 3). Thirteen patients underwent laparoscopic repair with mesh, and 3 patients had open repair. Two patients presented with strangulated hernias requiring laparotomy and bowel resection. Median follow-up time was 53 months (IQR, 12 to 141 months) for the entire cohort. One recurrence was noted (6.2%), in a patient with laparoscopic repair. CONCLUSIONS Diaphragmatic hernia repair after sequential LVAD explantation and orthotopic heart transplantation is feasible and appears to be safe. When this hernia is diagnosed, patients should be referred for surgical evaluation.

Abstract
BACKGROUND/PURPOSE Morgagni diaphragmatic hernia (MH) is rare. We report our experience based on routine patch use in MH repair to curb recurrence. A systematic review and meta-analysis were performed to study the recurrence and complications associated with minimally invasive surgery and the use of patch. METHODS We retrospectively reviewed all cases of MH who underwent first-time repair in 2012-2017 in our institution to determine recurrence and complication rate. A MEDLINE search related to minimally invasive surgery (MIS) and patch repair of MH was conducted for systematic review. Eligible articles published from 1997-2017 with follow-up data available were included. Primary outcomes measured were recurrence and complication. Meta-analysis to compare open versus MIS and primary versus patch repair in the MIS group were performed in comparative cohorts. Continuous data were presented as median (range), and statistical significance was P<0.05. RESULTS In our institution, 12 consecutive patients aged 17-month-old (22 days-7 years), underwent laparoscopic patch repair of MH, with one conversion to laparotomy. No recurrence or significant complication occurred over a follow-up period of 8 months (1-48 months). Thirty-six articles were included from literature review and were combined with the current series. All were retrospective case reports or series, of which 6 were comparative cohorts with both MIS and open repairs. A total of 296 patients from 37 series were ultimately used for analysis: 80 had open repair (4 patch) and 216 had MIS repair (32 patch), with a patch rate of 12%. There were 13 recurrences (4%): no difference between open and MIS repairs (4/80 vs 9/216, p=0.75); recurrence rate following primary repair was 13/260 (5%), but no recurrence occurred with 36 patch repairs. Meta-analysis showed no difference in recurrence between open and MIS repair (p=0.83), whereas patch repair was associated with 14% less recurrence compared with primary repair, although it did not reach statistical significance (p=0.12). There were 13 complications (5%): no difference between open and MIS repairs (5/80 vs 8/216, p=0.35). One small bowel obstruction occurred in a patient who had laparoscopic patch repair. CONCLUSION In MH, recurrence and complication rates are comparable between MIS and open repairs. Use of patch appeared to confer additional benefit in reducing recurrence. TYPE OF STUDY Systematic review LEVEL OF EVIDENCE: 3A.

Abstract
Congenital diaphragmatic hernia (CDH) is a rare congenital disease requiring neonatal surgical treatment. The traditional surgical management of CDH consists of diaphragmatic repair by laparotomy. Thoracoscopic repair techniques have been well described for CDH with late presentation. Nevertheless, its feasibility for CDH treatment in neonates emerged only the past few years because the use of thoracoscopy with carbon dioxide insufflation remains controversial in these patients more vulnerable to hypothermia and acidosis. However, we think that thoracoscopy can be safely used to repair CDH in selected patients and the major limiting factor is pulmonary hypoplasia. Some patients should be excluded based on their higher potential need for patch closure with its technical difficulty and increased operative time. The close collaboration between pediatric surgeon, anesthetist and neonatologist is essential. We discuss here the patient selection criteria, expose the pre- and post-operative management, the procedure steps; regarding to our experience we deliver some tips to achieve the safest surgical procedure for the pediatric patient.

Abstract
Neonatal surgery is recognized as an independent discipline in general surgery, requiring the expertise of pediatric surgeons to optimize outcomes in infants with surgical conditions. Survival following neonatal surgery has improved dramatically in the past 60 years. Improvements in pediatric surgical outcomes are in part attributable to improved understanding of neonatal physiology, specialized pediatric anesthesia, neonatal critical care including sophisticated cardiopulmonary support, utilization of parenteral nutrition and adjustments in fluid management, refinement of surgical technique, and advances in surgical technology including minimally invasive options. Nevertheless, short and long-term complications following neonatal surgery continue to have profound and sometimes lasting effects on individual patients, families, and society.

Abstract
Congenital diaphragmatic hernia is a birth defect that affects about one in 2500 live births. Although the overall survival has improved over the last several decades thanks to advancements in postnatal resuscitation and intensive care treatment, morbidity and mortality remain high. The surgical management of these infants is far from being standardized, and many aspects are still disputed among experts. The timing of surgical repair remains controversial and the indications for the ideal time for surgery have not been validated. The main novelty in the surgical treatment is related to the use of minimally invasive techniques, although these have been associated with intraoperative blood gas disturbances and higher recurrence rates. Herein, we report and comment on the main controversies of postnatal CDH repair in this rapidly evolving field.

Abstract
Thoracoscopic repair is feasible and safe for congenital diaphragmatic hernia (CDH). The operation can be performed with three trocars using carbon dioxide insufflations at a pressure of 4-6 mmHG. From January 2001 to July 2012, we performed thoracoscopic repair for 311 children with CDH including 152 newborns and 159 infants and toddlers. Mean operative time was 75 ± 27 min. HFOV was used in 24 patients. Direct closure of two rims of diaphragmatic hernia was carried out in 175 patients. Closure of two rims of diaphragmatic hernia with the thoracic wall was performed in 136 patients. Prosthetic patches were required in 54 patients. Conversion to open surgery was required in 38 patients (12.2%). There were no intraoperative deaths. 38 patients died postoperatively (13.5%).

Abstract
PURPOSE Publications aiming to prove the feasibility and safety of thoracoscopic CDH-repair in neonates grow in numbers. Some teams use selection criteria, but none have proven statistical evidence. The aim of this study is to detect risk factors for failure of thoracoscopic primary closure of CDH in neonates. METHODS In 8 centers performing minimal access surgery (MAS), complete prenatal, postnatal, and operative data were evaluated for a retrospective study concerning patients with thoracoscopic congenital diaphragmatic hernia (CDH) repair. Most of the selection criteria and risk factors mentioned in the literature were analyzed. Two groups were defined: Group A - neonates who tolerated thoracoscopic primary repair, and Group B - neonates who required conversion or presented with major complications after thoracoscopic repair. Univariate and multivariate logistic regressions were used to compare these two groups. RESULTS From 2006 to 2010, thoracoscopy was performed in 40 neonates: Group A consisting of 28 neonates, and Group B 9 patients. Three patients were excluded because of insufficient data or major associated malformations. Significant statistical differences were found in Group B for postnatal PaCO2 >60 mmHg, need of iNO during postnatal stabilization, intrathoracic position of the stomach, pulmonary hypertension signs on the postnatal cardiac ultrasound, and preoperative OI >3.0. On multivariate analysis, only an OI >3.0 was significantly associated with conversion or major post-operative complication of thoracoscopic primary repair. CONCLUSION CDH can be safely repaired in the neonatal period by thoracoscopy. The limiting factor for thoracoscopic CDH repair is PPHN. The best preoperative indicator for PPHN is OI. Prospective studies are nonetheless necessary to prove the effectiveness of using these risk factors as selection criteria to help design surgical management protocols for neonates presenting CDH.

Abstract
Surgical management of congenital diaphragmatic hernia (CDH) remains a challenge for all clinicians. While the treatment strategies for CDH have evolved from emergent surgical intervention to initial hemodynamic stabilization with delayed surgical repair, surgical innovations have remained limited in the last 20 years. Advances in surgical approaches, such as minimally invasive surgery and alternatives to diaphragmatic replacement, have focused on improvements in surgical morbidity.

Abstract
Repair of congenital diaphragmatic hernia (CDH) continues to pose a dilemma for the pediatric surgeon. While the management of CDH has evolved from surgical urgency to delayed repair after medical optimization with substantial improvements in mortality, morbidity continues to perplex clinicians. Significant morbidity occurs with recurrence, re-recurrence and complications such as obstructions, principally with mesh repair. When primary closure is not possible, mesh repair is indicated. While there are several non-absorbable prosthetic, absorbable biosynthetic and composite mesh types available, the ideal mesh remains elusive. In this article, we reviewed the current materials, reported advantages, and animal and clinical studies of non-absorbable prosthetic, absorbable biosynthetic and composite mesh. However, adequate comparative data are lacking, leaving a wide void for future animal models and clinical studies.

Simplified technique for minimally invasive repair of congenital diaphragmatic hernia using hollow-needle snare and transthoracic traction stitches. J Pediatr Surg 2012; 47:258-63.

Abstract
BACKGROUND Minimally invasive (MI) congenital diaphragmatic hernia (CDH) repair can be challenging. Placing rib-anchoring stitches without creating skin incisions and closing wider defects are some of the difficulties. In Bochdaleck hernia repair, maintaining visceral reduction and minimizing pneumothorax use are additional obstacles. We describe the use of hollow-needle snares (HNS) and transthoracic traction stitches (TTS) to overcome these challenges. METHODS Hollow-needle snares is assembled by passing a prolene stitch through a hollow needle creating a retractable snare, which is used to extract the placed anchoring stitches by passing it over the ribs but through the same stitch's skin entrance site. In Bochdaleck hernia, the early placement of TTS using HNS can facilitate visceral reduction, patch lay down, and tension-free closure of possible residual V-shaped defects. RESULTS Between July 2009 and April 2011, we performed 10 consecutive MI CDH repairs for 9 patients, including 7 Bochdaleck and 3 Morgagni hernias. The median age was 8 days (range, 3-172 days), and the mean operative time was 148.5 ± 37.8 minutes for Bochdaleck hernia repairs. For Morgagni hernia, the median age was 18.3 months (range, 10.5-37 months), and the mean operative time was 100 ± 26.5 minutes. All cases were completed without conversion. One patient had a hernia recurrence and was repaired similarly, whereas the others had uneventful recovery at a median follow-up of 5.8 months (range, 1.1-23.7 months). CONCLUSION Hollow-needle snare and TTS are simple and available tools that can facilitate MI repair of CDH. This initial experience demonstrates the technique's effectiveness and its excellent cosmetic outcomes.

Abstract
PURPOSE Operative approach, including minimally invasive surgery (MIS) in the repair of congenital diaphragmatic hernia (CDH), is variable among institutions. The short-term recurrent hernia rate is not well described. We evaluated the in-hospital recurrence rate of MIS repairs of infants with CDH from the Congenital Diaphragmatic Hernia Registry. METHODS Prospectively collected data from infants with CDH were analyzed from the Congenital Diaphragmatic Hernia Registry from January 1995 to January 2010. Recurrent hernia was defined as reoperations during initial hospitalization. Operative approaches included abdominal, thoracic, laparoscopic, and thoracoscopic techniques. RESULTS Five thousand four hundred eighty infants with CDH were identified, of which 4516 (82.4%) were repaired. Operative data were available in 4390 infants. One hundred fifty-one infants (3.4%) underwent MIS repairs with 12 reported recurrences (7.9%) compared with 114 for open techniques (2.7%, P < .05). Minimally invasive surgery demonstrated a significant increased odds for recurrence (odds ratio, 3.59; 95% confidence interval, 1.92-6.71) after adjusting for gestational age, birth weight, patch repair, and extracorporeal membrane oxygenation. CONCLUSION Minimally invasive techniques appear to have a significant higher recurrent hernia rate, with thoracoscopy being the highest. Although adjusted for patch repair, other factors with regard to disease severity may contribute to differences in outcomes among centers. This study is limited to short-term recurrence during initial hospitalization.

Abstract
AIM The aim of this work was to report the technique and result of thoracoscopic repair for a newborn with congenital diaphragmatic hernia (CDH) under high-frequency oscillatory ventilation (HFOV) in the neonatal intensive care unit (NICU). METHODS Ventilation was supported by HFOV. The patient was placed in the right lateral decubitus position. Thoracoscopic surgery was performed through three 5-mm trocars. Carbon dioxide insufflation was maintained in the thoracic cavity at a pressure of 6-8 mm Hg. The hernia defect was repaired by using interrupted sutures with extracorporeal knots. RESULTS The operation lasted 60 minutes. The intraoperative course was uneventful. Normal vital signs and PO(2) value were maintained throughout the operation. The patient had a normal chest X-ray 1 month after discharge. CONCLUSION Thoracoscopic repair of CDH in the NICU during HFOV is feasible and safe.

Abstract
OBJECTIVE To compare outcomes of open and endosurgical neonatal congenital diaphragmatic hernia (CDH) repairs. BACKGROUND Historically a surgical emergency, neonatal CDH repair is now deferred pending stabilization of characteristically labile cardiopulmonary physiology. Usually accomplished via laparotomy, surgical repair may acutely worsen lung function; conversely, by reducing the visceral hernia, surgery might improve it. Theoretically, endosurgical repair could minimize deleterious effects of surgery while garnering benefits from decompressing the CDH lung. As endosurgical repair gains popularity, it is important to investigate whether or not minimally-invasive neonatal CDH repair has benefits. METHODS We searched Medline, Embase, and Cochrane Trials databases for studies comparing open with endosurgical CDH repair. Non-neonatal series and reports without comparison groups were excluded. References from papers and conference proceedings were also hand searched. Meta-analysis used a fixed effects model and was reported in accordance with PRISMA. RESULTS We included 3 studies (1 unpublished; none randomized); all compared thoracoscopic and open CDH repair and together described 143 patients. All studies had limitations, including use of historical controls. Demographics, CDH sidedness, APGAR and associated anomaly prevalence were similar between groups. For endosurgical repair, recurrence was higher (RR: 3.2 [1.1, 9.3], P = 0.03) and operative time longer (WMD 50 minutes [32, 69], P < 0.00001). Survival and patch usage were not different between open and endosurgical groups. CONCLUSIONS Neonatal thoracoscopic CDH repair has greater recurrence rates and operative times but similar survival and patch usage compared with open surgery. A prospective registry for all such cases would guide development of trials (Stage 2b; IDEAL recommendations).

Abstract
BACKGROUND/PURPOSE Surgical complications are common in survivors of congenital diaphragmatic hernia (CDH), but little is known about long-term incidence patterns and associated predictors. METHODS A cohort of 99 CDH survivors was prospectively followed at a single-institution multidisciplinary clinic. Data were gathered regarding the adverse surgical outcomes of hernia recurrence, chest and spinal deformity, and operative small bowel obstruction (SBO), and then were retrospectively analyzed in relation to perinatal and perioperative markers of disease severity to determine significant predictors. Statistical methods used included univariate and multivariate regression analysis, hazard modeling, and Kaplan-Meier analysis. RESULTS At a median cohort age of 4.7 (range, 0.2-10.6) years, 46% of patients with patch repairs and 10% of those with primary repairs had a hernia recurrence at a median time of 0.9 (range, 0.1-7.3) years after repair. Chest deformity was detected in 47%. Small bowel obstruction and scoliosis occurred in 13%. Recurrence and chest deformity were significantly more common with patch repair, liver herniation, age at neonatal extubation greater than 16 days, oxygen requirement at discharge, and prematurity. The strongest predictor of SBO was patch repair. Multivariate analysis showed that patch repair was independently predictive of recurrence and early chest deformity (odds ratios of 5.0 and 4.8, confidence intervals of 1-24 and 1-21, P < .05). Use of an absorbable patch was associated with the highest risk of surgical complications. CONCLUSIONS For long-term survivors of CDH, specific perinatal and operative variables, particularly patch repair, are associated with subsequent adverse surgical outcomes.

Abstract
PURPOSE Congenital diaphragm anomalies, including eventration, Morgagni diaphragmatic hernias (M-CDH), and Bochdalek diaphragmatic hernias (B-CDH), have been successfully repaired by using minimally invasive surgery (MIS). However, some reports have shown a high recurrence rate for some defects, potentially due to difficulty associated with the rigid instruments. Robotic surgery may help close diaphragmatic anomalies more effectively. In this paper, we present a series of 8 consecutive patients with diaphragmatic anomalies who underwent robotic repair. METHODS We retrospectively reviewed patients with diaphragmatic anomalies. There were 2 patients with eventration, 5 with B-CDH, and 1 with M-CDH. All procedures were performed by using the Standard Da Vinci surgical robot (Intuitive Surgical, Sunnyvale, CA) with one camera arm (5-mm two-dimensional scope) and two instrument arms (5 mm). RESULTS Average age was 3.9 months (4 days to 12 months). Average weight was 3.6 kg (range, 2.2-10.5). Four B-CDH patients were approached through the chest and 1 from the abdomen. The patient with M-CDH had an abdominal repair, and both eventrations were performed from the chest. One B-CDH and 1 eventration were converted to thoracoscopic procedures. Average operative time was 1 hour and 20 minutes. One recurrence developed in a relatively large B-CDH repair that was closed primarily. Average follow-up was 20 months. CONCLUSIONS Robotic surgery is safe and effective for repairing diaphragm anomalies in small children. Although we prefer the thoracic approach for repairing the B-CDH, occasionally smaller newborns-perhaps those less than 2.5 kg-may do better with the abdominal approach, since the articulating instruments requiring a significant length in order to maneuver.

Abstract
BACKGROUND Delayed presentation of a congenital diaphragmatic hernia (CDH) is not usual. Primary laparoscopic repair is becoming the standard in many centers. Different approaches and techniques have been proposed. There is not enough evidence in the literature to recommend one technique over another. PATIENTS AND METHODS In this paper, we report one case of Morgagni hernia (MH) and one case of Bochdalek hernia (BH), 2 and 6 years old, respectively, operated on in our hospital. In the first case, the diaphragmatic defect was directly sutured with extracorporeal interrupted nonabsorbable sutures, passed through the abdominal wall with a Reverdin needle. In the second one, intracorporeal nonabsorbable stitches were placed. A search of the literature was made using PubMed and the following words: congenital diaphragmatic hernia, laparoscopy or thoracoscopy, and children. The neonatal Bochdalek hernias were discarded. Data about surgical approach, suturing technique, management of the hernia sac, complications, and recurrence were summarized for both pathologies. RESULTS Both patients were discharged 48 hours after surgery. There were no complications. No recurrence was evident after 6 months. Eleven articles on the treatment of MHs were found, with a total of 30 patients. For BHs, 10 articles met the inclusion criteria, with a total of 54 patients. In both groups, all the papers were case reports or retrospective reviews of case series. The MH is best approached through laparoscopy, and the BH can be treated through thoracoscopy or laparoscopy. Most researchers prefer direct suture with nonabsorbable material. Both complication and recurrence rates are very low. CONCLUSIONS The endoscopic approach of late-presenting Morgagni and Bochdalek CDH is a safe technique. It offers all the advantages of minimally invasive surgery (MIS), and laparoscopy also permits the diagnosis and treatment of other associated conditions. There are a short number of cases reported and no prospective study comparing open with the MIS approach for the treatment of diaphragmatic malformations.

Abstract
PURPOSE To assess intraperitoneal adhesion formation in rats after the single implantation of intraperitoneal polypropylene mesh versus SIS mesh, and the effect of PAF as a polypropylene mesh barrier. METHODS A total of 55 albino rats randomized into three groups were assessed. The type of adhesions, the percentage of mash covered with adhesions, and the rupture strength of the adhesions were evaluated. RESULTS The type 2 and 3 adhesions were more frequent in group 1 (polypropylene mesh) and group 3 (Polypropylene+PAF), while type 0 and 1 adhesions were more frequent in group 2 (SIS). The mean rupture strength was 1,58 N (+/-0,719N) in group 1, 0,42 N (+/-0,432N) in group 2 and 1,23 N (+/-0,432N) in group 3. Over 50% of the mash was covered with adhesions in 12 (80%) cases of the group 1, in 4 (20%) cases of the group 2 and in 16 (84,2%) cases of the group 3. Group 2 differed significantly (p<0.001) from the other groups. CONCLUSIONS Implantation of intraperitoneal polypropylene mesh yielded higher rates of adhesion and the use of PAF as a mesh barrier didn't reduced the rates of adhesion. SIS mesh implantation revealed lower rates of peritoneal adhesions.

Abstract
A 75-year-old woman who presented with a cough was found on investigation to have a large right-sided diaphragmatic hernia with intrathoracic herniation of the colon, small bowel, and right kidney. The patient denied any history of trauma and therefore the hernia was felt to be congenital in nature. The patient underwent a combined laparoscopic repair with polytetrafluoroethylene mesh and a thoracoscopic lysis of adhesions of the posterior right-sided diaphragmatic hernia. To our knowledge, this is the first reported case of a combined laparoscopic and thoracoscopic repair of a congential diahphragmatic hernia. Although successful repair can be accomplished laparoscopically, the addition of a thoracoscopic lysis of adhesions facilitated the early reexpansion of our patient's chronically scarred lung.

Abstract
BACKGROUND Minimally invasive surgery (MIS) for late-presenting congenital diaphragmatic hernia (CDH) has been described previously, but few neonatal cases of CDH have been reported. This study aimed to report the multicenter experience of these rare cases and to compare the laparoscopic and thoracoscopic approaches. METHODS Using MIS procedures, 30 patients (16 boys and 14 girls) from nine centers underwent surgery for CDH within the first month of life, 26 before day 5. Only one patient had associated malformations. There were 10 preterm patients (32-36 weeks of gestational age). Their weight at birth ranged from 1,800 to 3,800 g, with three patients weighing less than 2,600 g. Of the 30 patients, 18 were intubated at birth. RESULTS The MIS procedures were performed in 18 cases by a thoracoscopic approach and in 12 cases by a laparoscopic approach. No severe complication was observed. For 20 patients, reduction of the intrathoracic contents was achieved easily with 15 thoracoscopies and 5 laparoscopies. In six cases, the reduction was difficult, proving to be impossible for the four remaining patients: one treated with thoracoscopy and three with laparoscopy. The reasons for the inability to reduce the thoracic contents were difficulty of liver mobilization (1 left CDH and 2 right CDH) and the presence of a dilated stomach in the thorax. Reductions were easier for cases of wide diaphragmatic defects using thoracoscopy. There were 10 conversions (5 laparoscopies and 5 thoracoscopies). The reported reasons for conversion were inability to reduce (n = 4), need for a patch (n = 5), lack of adequate vision (n = 4), narrow working space (n = 1), associated bowel malrotation (n = 1), and an anesthetic problem (n = 1). Five defects were too large for direct closure and had to be closed with a patch. Four required conversion, with one performed through video-assisted thoracic surgery. The recurrences were detected after two primer thoracoscopic closures, one of which was managed by successful reoperation using thoracoscopy. CONCLUSIONS In the neonatal period, CDH can be safely closed using MIS procedures. The overall success rate in this study was 67%. The indication for MIS is not related to weeks of gestational age, to weight at birth (if >2,600 g), or to the extent of the immediate neonatal care. Patients with no associated anomaly who are hemodynamically stabilized can benefit from MIS procedures. Reduction of the herniated organs is easier using thoracoscopy. Right CDH, liver lobe herniation, and the need for a patch closure are the most frequent reasons for conversion.

Abstract
Biologic grafts for hernia repair are a relatively new development in the world of surgery. A thorough search of the Medline database for uses of various biologic grafts in hernia shows that the evidence behind their application is plentiful in some areas (ventral, inguinal) and nearly absent in others (parastomal). The assumption that these materials are only suited for contaminated or potentially contaminated surgical fields is not borne out in the literature, with more than 4 times the experience being reported in clean fields and the average success rates being higher (93% vs 87%). Outcomes prove to be highly dependent on material source, processing methods and implant scenarios with failure rates ranging from zero to more than 30%. Small intestinal submucosa (SIS) grafts have an aggregate failure rate of 6.7% at 19 months whereas acellular human dermis (AHD) grafts have a failure rate of 13.6% at 12 months. Chemically cross-linked grafts have much less published data than the non-cross-linked materials. In particular, the search found 33 articles for SIS, 32 for AHD, and 13 for cross-linked porcine dermis. Furthermore, the cumulative level of evidence for each graft material was fairly low (2.6 to 2.9), and only 1 material (SIS) had level 1 evidence reported in any hernia type (inguinal and hiatal). Together, biologic grafts have published evidence showing success rates better than 90% overall and more than 2000 years of cumulative implant time. Improvements in materials, techniques, and patient selection are likely to improve these numbers as this field of surgery matures.

Abstract
Significant advances in the postnatal management of patients with congenital diaphragmatic hernia (CDH) have resulted in a remarkable improvement in survival rates over the past two decades. The success of current postnatal management of CDH patients has rendered fetal intervention to be limited to the most severe cases, and the role for prenatal treatment of CDH patients remains unclear. The adoption of lung-preserving strategies including high-frequency oscillatory ventilation (HFOV) and extracorporeal membrane oxygenation (ECMO) have improved CDH outcomes especially in those patients with significant ventilatory or circulatory compromise. Survival rates of up to 90% are being reported in some high-volume centers. However, the increased survival in CDH patients has been accompanied by an increase in neurological, nutritional and musculoskeletal morbidity among the long-term survivors. This has resulted in the need to provide resources for the long-term follow-up and support of this patient population. In this article, the postnatal management strategies and primary and secondary outcomes of high-volume international pediatric surgical centers will be reviewed. Finally, the role of a multidisciplinary management team for the follow-up of long-term CDH survivors will be discussed.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (SG) is an accepted bariatric procedure, with an advantaged by a low complication rate. A feared complication is stapler line leak. Buttressing materials have been suggested as a means of reducing staple line leak rates. We analyzed the leak rates from published series to help in demonstrating a potential cause. METHODS The study was institutional review board (IRB) approved retrospectively. A Medline search using the key words sleeve gastrectomy and bariatric surgery obtained 54 articles. Attention was restricted to 11 articles written in English that listed numbers of gastrectomy procedures and leaks. Poisson regression assessed the possibility that patients who received buttressing materials had a reduced rate of leaks. RESULTS Thirty-five patients were evaluated from Greece (15) and the United States (20); two patients developed staple line leaks that appeared to be related to problems associated with buttressing materials. Eleven prior studies and the present series yielded 1,589 procedures, 15 (0.94%) of which were complicated by leaks. The leak rate for patients who were known to have received reinforcement of some sort was 1.45 (95% confidence interval 0.41-3.43) times that for other patients. To detect a difference between 1% and 0.5% as statistically significant in 80% of cases, with a two tailed test and alpha set at 0.05, would require 9,346 procedures. CONCLUSIONS There is no reason to believe, at this point, that reduction in leak rates occur because reinforcement is used. Because the leak rate is small, the routine reinforcement of the staple line after sleeve gastrectomy is questionable at best, although a decrease in hemorrhage has been reported.

Abstract
Needlescopic techniques have been used recently in different pediatric procedures, which made this type of surgery more feasible and less invasive with decreased hospital stay and improved cosmetic results. The technique is being developed further. New techniques with minor modifications are evolving every day. The objective of this study was to describe and assess the results that can be achieved by using a new simplified technique [Reverdin needle (RN)] in thoracoscopic repair of diaphragmatic hernia in neonates and children. Eighteen patients with symptomatic congenital diaphragmatic hernia (CDH), from Al-Azhar University Hospitals, Cairo, Egypt were assigned to elective thoracoscopic repair using RN to insert mattress sutures between the edges of diaphragmatic defects. The technique will be described in detail. A total of 18 diaphragmatic defects were repaired successfully; there were 12 males and 6 females with a mean age of 1.58 +/- 21 months (range, 5 days-9 months). Left-sided CDH was present in 12 cases (67%) and right-sided CDH in 6 cases (33%). The mean operative time was 30.7 +/- 1.18 min (range, 25-60 min) for each CDH repair. There were no intra or postoperative complications. There was one case of conversion and minimal blood loss. The mean postoperative hospital stay was 5.6 days (range, 2-10 days). There was only one case of mortality on the 10th postoperative day. There was no single case of recurrence. The new technique had all the advantages of thoracoscopy in children (less invasive, less pain, shorter hospital stay) combined with the advantages of reduced operating time, simplicity and feasibility. It may be preferable to intracorporeal suturing and knot tying.

Abstract
Minimal invasive surgery (MIS) has been first proposed in case of delayed congenital diaphragmatic hernia (CDH). Since then, about 32 cases of thoracoscopic CDH approach in newborns have been published. Conditions of thoracoscopy are reviewed and enlightened with our preliminary series. The advantages of thoracoscopy versus a laparoscopic approach are detailed. Since 1999, all children presenting with CDH after the immediate neonatal period were offered a MIS approach. We started treating stable newborns suffering a CDH by thoracoscopic procedures in 2003. In cases of late presentations, 10 thoracoscopies and 1 laparoscopy were performed. Among them, 4 patients suffered from an incarcerated hernia. One conversion to a thoracotomy, 1 video-assisted thoracic surgery (VATS), and 2 conversions to laparoscopies were required for the reduction of hernia contents. In those last cases, the hernia defects were sutured, coming back to the thoracoscopic approach. Six newborns with neonatal diagnosis of CDH were primarily treated by thoracoscopy. Four procedures were completed without difficulty. The diaphragm was approximated with interrupted 2/0 nonabsorbable sutures. On the lateral part of the defect, in which there is a lack of diaphragm against the ribs, plegetted rib-anchoring stitches were used. A wide defect requiring a patch needed for conversion to a thoracotomy; in this case, we encountered a very rare pericardial defect and had difficulties in reducing the liver. In another case, we went to a VATS with a less than 2-cm opening to insert a Gore Tex patch, which was required. Thoracoscopy for delayed CDH repair seems to be easy and feasible with good results. A combined procedure with both thoracoscopy and laparoscopy has proven its usefulness in case of incarcerated hernia. Thoracoscopic CDH repair in newborns is not feasible in every case due to the patient's conditions. Criteria for eligibility need more cases to be evaluated. The advantages and disadvantages of thoracoscopy versus laparoscopy are reviewed. Nevertheless, the thoracoscopic approach seems easier.

Abstract
Abdominal wall reconstruction in omphalopagus twins poses a difficult reconstructive challenge, as separation often results in a large abdominal wall defect. A number of options are available for closure, including tissue flaps, expanders and patches made of foreign material. Surgisis is a new biodegradable small intestine scaffolding substrate that permits tissue in-growth and results in a permanent durable scar. We describe its use in abdominal wall reconstruction after separation of a set of conjoined twins. A set of omphalopagus conjoined twins shared liver and abdominal wall. After separation at 6 months of age, Twin A's abdomen could be closed primarily, but Twin B could not. A 4-ply Surgisis mesh was used in the upper abdominal closure, and a skin flap was created, to completely cover the patch. Both twins survived the operation. A small portion of the skin flap over the Surgisis broke down, healing by secondary intention. In follow up of over 18 months post procedure, there have been no wound infections and the abdominal wall is intact with no evidence of a hernia. Surgisis can be successfully used for the reconstruction of complex abdominal wall defects in the pediatric patient, including reconstruction after separation of conjoined twins.

Abstract
CASE DESCRIPTION 3 Horses were examined and treated because of sudden onset of signs of abdominal pain. CLINICAL FINDINGS All horses had a retrosternal (Morgagni) hernia involving the right side of the diaphragm. In each horse, the large colon was incarcerated in a right muscular defect in the diaphragm with a large hernial sac. TREATMENT AND OUTCOME Definitive surgical repair of the hernia was not performed during the initial celiotomy. The hernia was repaired with mesh herniorrhaphy, but without resection of the hernia sac in 2 horses. For 1 horse, conservative management was applied. In the 2 horses treated with surgical correction, no major postoperative complications developed, and all 3 horses have been free of signs of abdominal pain. CLINICAL RELEVANCE Horses with retrosternal hernias involving the diaphragm can develop clinical signs of intermittent obstruction of the large colon and chronic colic. In horses, retrosternal diaphragmatic hernias appear to develop exclusively in the right ventral aspect of the diaphragm and could represent an embryologic defect of diaphragm formation. Affected horses can be successfully treated with mesh herniorrhaphy or, in some instances, with conservative management.

Abstract
BACKGROUND Numerous techniques exist for repairing large congenital diaphragmatic hernias (CDHs) including prosthetic patches, tissue-engineered grafts, and various muscle flaps. A split abdominal wall muscle flap is a simple, durable way to repair a large diaphragmatic hernia. This technique has not gained widespread use, and some have suggested that it would be inappropriate in the setting of extracorporeal membrane oxygenation (ECMO) because of bleeding risk. We present our series of diaphragmatic hernias with a focus on those repaired with the split abdominal wall technique while on ECMO. METHODS A retrospective, single-institution chart review was performed on all patients who underwent surgical repair for CDH over 6 years beginning in August 2000. RESULTS Seventy-five patients underwent repair. Sixteen were performed with patients on ECMO. Of these, 4 were closed primarily, 7 used a prosthetic patch, and 5 used a split abdominal wall muscle flap. Two patients in the prosthetic group developed a recurrent hernia, and 2 required reoperation for bleeding while on ECMO. No reoperations for bleeding were required in the abdominal muscle flap group. CONCLUSIONS The split abdominal wall muscle flap can be safely performed on anticoagulated patients. We believe it is a practical option for repairing large CDHs.

Abstract
Chest wall reconstruction following major tumour resection remains a challenging problem in the paediatric population due to the need for growth and development following the repair. Synthetic non-biodegradable grafts and materials have led to asymmetrical growth and significant functional and cosmetic compromise. The ideal graft material should be biological non-immunogenic which enables natural healing and facilitates further growth. Ewing's sarcoma is an uncommon primitive neuroectodermal tumour which rarely occurs in the ribs. However, recent improvements in management have produced a significantly improved survival; increasing the importance of chest wall reconstruction. We prospectively assessed the utilisation of Surgisis (an acellular collagen matrix) as a replacement graft in two children undergoing primary chest wall reconstruction following tumour resection. Surgisis is derived from porcine small intestinal submucosa (SIS) that serves as a template for tissue reconstruction and remodeling. The graft was well tolerated; there was no herniation and it allowed normal symmetrical chest movement and growth to occur. The properties of SIS allows natural collagen growth and compares favourably with marlex mesh and other forms of chest wall reconstruction. We believe its unique properties allow it to act as a suitable framework for chest wall reconstruction allowing chest wall growth and development.

Abstract
Biomaterials offer the surgeon a powerful set of clinical tools for patient treatment and are found in virtually every instrument, device, implant, or piece of equipment in the operating room. In fact, surgeons have historically driven clinical application of biomaterials and stand uniquely positioned to contribute to the ongoing development of biomaterials. Having an understanding of the materials available and their basic properties can contribute to better and more effective outcomes. This article provides an overview of the biomaterials field. It begins with a definition and abbreviated history of the field, highlighting its clinical roots. An introduction to the four material classifications--metals, polymers, ceramics, and composites--is then presented, providing the reader with basic properties of each group and examples of materials. Sections on nanotechnology and tissue engineering also briefly describe development within the field. Finally, the evolution of treatments for pectus excavatum and congenital diaphragmatic hernias are presented, highlighting the role of biomaterials. While providing a primer of the field, this paper shows the broad interdisciplinary reach of material science in surgery and suggests sources for further investigations.

Abstract
Congenital diaphragmatic hernia usually presents in the neonatal period, with delayed presentation being uncommon. Traditionally repair was performed by laparotomy or thoracotomy. We have performed laparoscopic repair of a previously undiagnosed congenital diaphragmatic hernia that presented acutely in a 10-year-old male. Laparoscopic repair of late-presenting congenital diaphragmatic hernia is a safe and effective approach even in an emergency. The laparoscopic approach has advantages including reduced hospital stay, excellent visualisation of the defect even for obese patients, and improved cosmesis.

Abstract
Congenital diaphragmatic hernia (CDH) retains high mortality due to lung hypoplasia and pulmonary hypertension. Efforts to improve survival and outcome have included fetal intervention, delivery at specialist centres, elective operation after stabilisation of labile physiology and minimising barotrauma. Permissive hypercapnea ('gentle ventilation') represents a significant advance in therapy gaining wider acceptance in centres worldwide. Human genetic studies are underway to identify candidate genes for the birth defect. Progress in the basic sciences may uncover critical aspects of developmental biology fundamental to CDH. Clinical trends in perinatal management of CDH are highlighted, which underpin the challenges of this lethal human anomaly.
