Development of a low-cost congenital abdominal wall defect simulator (wall-go) for undergraduate medical education: a validation study.

BACKGROUND: Congenital Anomalies were responsible for 303,000 deaths in the neonatal period, according to the WHO, they are among the world's top 20 causes of morbidity and mortality. Expensive simulators demonstrate several diseases, but few are related to congenital anomalies. This study aims to develop, validate, and evaluate low-cost simulator models (WALL-GO) of the most common abdominal wall defects, gastroschisis, and omphalocele, to enable diagnosis through an accessible tool with study value and amenable to replication. METHODS: Market research was conducted to find materials to build low-cost models. The researchers built the model and underwent validation assessment of the selected experts who scored five or more in the adapted Fehring criteria. The experts were assessed through a 5-point Likert scale to 7 statements (S1-7). Statements were assigned values according to relevance in face and transfer validities. Concomitantly, the model was also evaluated by students from 1st to 5th year with the same instruments. Content Validity Indexes (CVIs) were considered validated between groups with concordance greater than 90%. Text feedback was also collected. Each statement was subjected to Fisher's Exact Test. RESULTS: Gastroschisis and omphalocele model costs were US $15 and US $27, respectively. In total, there were 105 simulator evaluators. 15 experts were selected. Of the 90 students, there were 16 (1st year), 22 (2nd), 16 (3rd), 22 (4th), and 14 (5th). Students and experts obtained CVI = 96.4% and 94.6%, respectively. The CVIs of each statement were not significantly different between groups (p < 0,05). CONCLUSIONS: The WALL-GO models are suitable for use and replicable at a manufacturable low cost. Mannequins with abdominal wall defects are helpful in learning to diagnose and can be applied in teaching and training health professionals in developing and low-income countries.

Giant Omphaloceles-Morbidity, Mortality, and Financial Impact of Early Versus Delayed Repair.

INTRODUCTION: We compared strategy outcomes and financial impact over the first two years of life (F2YOL) for patients with giant omphaloceles undergoing early repair (ER) (primary or staged) versus delayed repair (DR). METHODS: A retrospective review of giant omphaloceles (fascial defect > 5 cm/> 50% liver herniation) at a tertiary children's hospital between 1/1/2010 and 12/31/2019 was performed. Survival, length of stay, age at repair, ventilation days (VD), time to full enteral feeds, readmissions during the F2YOL, incidence of major associated anomalies, and total hospitalization charges during the F2YOL were compared. A subanalysis removing potential confounders and only including patients who underwent fascial closure within the F2YOL was also conducted. RESULTS: Thirty four giant omphaloceles (23DR and 11ER) were identified. The median age (days) at repair was 289 [148, 399] DR versus 10 [5, 21] ER, P < 0.001. Total cohort two-year survival was significantly higher in the DR group (95.7% versus 63.6%, P = 0.03). Including patients with a tracheostomy there was no significant difference in VD during the index hospitalization. Excluding tracheostomy patients, the DR group had significantly fewer VD during the index hospitalization, 15 [0, 15] versus 18 [10, 54], P = 0.02 and over the F2YOL 6.5 [ 0, 21] versus 18 [14, 43], P = 0.03. There were no significant differences in the incidence/type of major associated anomalies, time to full enteral feeds, index length of stay, total hospital days, total admissions, or associated hospital charges. On subanalysis, there was no significant difference in VD or survival at any time. CONCLUSIONS: Delayed and early repair strategies for giant omphaloceles have equivalent outcomes in the index hospitalization and over the course of the first two years of life. These findings are useful for family counseling and expectation setting.

Cirrhosis and hernia repair in a cohort of 6352 patients in a tertiary hospital: Risk assessment and survival analysis.

The prevalence of hernias in patient with cirrhosis can reach up to 40%. The pathophysiology of cirrhosis is closely linked to that of the umbilical hernia, but other types are also common in this population. The aim of this study is to evaluate factors that influence in the prognosis after hernia repair in patients with cirrhosis. A historical cohort of 6419 patients submitted to hernia repair was gathered. Clinical, epidemiological data and hernia characteristics were obtained. For patient with cirrhosis, data from exams, surgery and follow-up outcomes were also analyzed. Survival curves were constructed to assess the impact of clinical and surgical variables on survival. 342 of the 6352 herniated patients were cirrhotic. Patient with cirrhosis had a higher prevalence of umbilical hernia (67.5% × 24.2%, P < .001) and a lower prevalence of epigastric (1.8% × 9.0%, P < .001) and lumbar (0% × 0.18%, P = .022). There were no significant differences in relation to inguinal hernia (P = .609). Ascites was present in 70.1% of patient with cirrhosis and its prevalence was different in relation to the type of hernia (P < .001). The survival curve showed higher mortality for emergency surgery, MELD > 14 and ascites (HR 12.6 [3.79-41.65], 4.5 [2.00-10.34], and 6.1 [1.15-20.70], respectively, P < .05). Hernia correction surgery in patient with cirrhosis has a high mortality, especially when performed under urgent conditions associated with more severe clinical conditions of patients, such as the presence of ascites and elevated MELD.

Chances of Mortality Are 3.5-Times Greater in Elderly Patients with Umbilical Hernia Than in Adult Patients: An Analysis of 21,242 Patients.

The goal of this study was to identify risk factors that are associated with mortality in adult and elderly patients who were hospitalized for umbilical hernia. A total of 14,752 adult patients (ages 18−64 years) and 6490 elderly patients (ages 65+), who were admitted emergently for umbilical hernia, were included in this retrospective cohort study. The data were gathered from the National Inpatient Sample (NIS) 2005−2014 database. Predictors of mortality were identified via a multivariable logistic regression, in patients who underwent surgery and those who did not for adult and elderly age groups. The mean (SD) ages for adult males and females were 48.95 (9.61) and 46.59 (11.35) years, respectively. The mean (SD) ages for elderly males and females were 73.62 (6.83) and 77.31 (7.98) years, respectively. The overall mortality was low (113 or 0.8%) in the adult group and in the elderly group (179 or 2.8%). In adult patients who underwent operation, age (OR = 1.066, 95% CI: 1.040−1.093, p < 0.001) and gangrene (OR = 5.635, 95% CI: 2.288−13.874, p < 0.001) were the main risk factors associated with mortality. Within the same population, female sex was found to be a protective factor (OR = 0.547, 95% CI: 0.351−0.854, p = 0.008). Of the total adult sample, 43% used private insurance, while only 18% of patients in the deceased population used private insurance. Conversely, within the entire adult population, only about 48% of patients used Medicare, Medicaid, or self-pay, while these patients made up 75% of the deceased group. In the elderly surgical group, the main risk factors significantly associated with mortality were frailty (OR = 1.284, 95% CI: 1.105−1.491, p = 0.001), gangrene (OR = 13.914, 95% CI: 5.074−38.154, p < 0.001), and age (OR = 1.034, 95% CI: 1.011−1.057, p = 0.003). In the adult non-operation group, hospital length of stay (HLOS) was a significant risk factor associated with mortality (OR = 1.077, 95% CI: 1.004−1.155, p = 0.038). In the elderly non-operation group, obstruction was the main risk factor (OR = 4.534, 95% CI: 1.387−14.819, p = 0.012). Elderly patients experienced a 3.5-fold higher mortality than adult patients who were emergently admitted with umbilical hernia. Increasing age was a significant risk factor of mortality within all patient populations. In the adult surgical group, gangrene, Medicare, Medicaid, and self-pay were significant risk factors of mortality and female sex was a significant protective factor. In the adult non-surgical group, HLOS was the main risk factor of mortality. In the elderly population, frailty and gangrene were the main risk factors of mortality within the surgical group, and obstruction was the main risk factor for the non-surgical group.

Assessment of potential influencing factors on the outcome in small (< 2 cm) umbilical hernia repair: a registry-based multivariable analysis of 31,965 patients.

INTRODUCTION: How best to treat a small (< 2 cm) umbilical hernia continues to be the subject of controversial debate. The recently published guidelines for treatment of umbilical hernias from the European Hernia Society and Americas Hernia Society recommend open mesh repair for defects ≥ 1 cm. Since the quality of evidence is limited for hernias with defect sizes smaller than 1 cm, suture repair can be considered. To date, little is known about the potential influencing factors on the outcome in small (< 2 cm) umbilical hernia repair. This multivariable analysis of data from the Herniamed Registry now aims to assess these factors. METHODS: The data of patients with primary elective umbilical hernia repair and defect size < 2 cm entered into the Herniamed Registry from September 1, 2009 to December 31, 2018 were analyzed to assess through multivariable analysis all confirmatory pre-defined potential influencing factors on the primary outcome criteria intraoperative and postoperative complications, general complications, complication-related reoperations, recurrence rate and rates of pain at rest, pain on exertion and chronic pain requiring treatment at 1-year follow-up. RESULTS: 31,965 patients (60%) met the inclusion criteria. The proportion of suture repairs was 78.6% (n = 25,119), of open mesh repairs 15.2% (n = 4853), and of laparoscopic mesh repairs 6.2% (n = 1993). Compared with open mesh repair, suture repair had a highly significantly unfavorable association with the recurrence rate (OR = 1.956 [1.463; 2.614]; p < 0.001). Female gender also had an unfavorable relation to the recurrence rate (OR = 1.644 [1.385; 1.952]; p < 0.001). Compared with open mesh repair, open suture repair had a highly significantly favorable association with the rate of postoperative complications (OR = 0.583 [0.484; 0.702]; p < 0.001) and complication-related reoperations (OR = 0.567 [0.397; 0.810]; p = 0.002).While laparoscopic IPOM showed a favorable relationship with the postoperative complications and complication-related reoperations, it demonstrated an unfavorable association with the intraoperative complications, general complications, recurrence rate and pain rates. CONCLUSION: Suture repair continues to be used for 78% of umbilical hernias with a defect < 2 cm. While suture repair has a favorable influence on the rates of postoperative complications and complication-related reoperations, it has a higher risk of recurrence. Female gender also has an unfavorable influence on the recurrence rate. Laparoscopic IPOM appears to be indicated only in settings of obesity (BMI ≥ 30).

Age-Dependent Costs and Complications in Pediatric Umbilical Hernia Repair.

OBJECTIVES: To characterize regional variation in the age of patients undergoing umbilical hernia repair to determine costs and subsequent care. STUDY DESIGN: We performed a cross-sectional descriptive study using a large convenience sample of US employer-based insurance claims from July 2012 to December 2015. We identified children younger than 18 years of age undergoing uncomplicated (not strangulated, incarcerated, or gangrenous) umbilical hernia repair as an isolated procedure (International Classification of Diseases, Ninth Revision procedure codes 53.41, 53.42, 53.43, or 53.49, International Classification of Diseases, Tenth Revision procedure code 0WQF0ZZ, or Current Procedural Terminology procedure codes 49580 or 49585). RESULTS: In all, 5212 children met criteria for inclusion. Children younger than age 2 years accounted for 9.7% of repairs, with significant variation by census region (6% to 14%, P < .001). Total payments for surgery varied by age; children younger than 2 years averaged $8219 and payments for older children were $6137. Postoperative admissions occurred at a rate of 73.1 per 1000 for children younger than age 2 years and 7.43 for older children; emergency department visits were 41.5 per 1000 for children younger than age 2 years vs 15.9 for older children (P < .001). CONCLUSIONS: Umbilical hernias continue to be repaired at early ages with large regional variation. Umbilical hernia repair younger than age 2 years is associated with greater costs and greater frequency of postoperative hospitalization and emergency department visits.

Variations in Nationwide Readmission Patterns after Umbilical Hernia Repair.

Up to one in three readmissions occur at a different hospital and are thus missed by current quality metrics. There are no national studies examining 30-day readmission, including to different hospitals, after umbilical hernia repair (UHR). We tested the hypothesis that a large proportion were readmitted to a different hospital, that risk factors for readmission to a different hospital are unique, and that readmission costs differed between the index and different hospitals. The 2013 to 2014 Nationwide Readmissions Database was queried for patients admitted for UHR, and cost was calculated. Multivariate logistic regression identified risk factors for 30-day readmission at index and different hospitals. There were 102,650 admissions for UHR and 8.9 per cent readmissions, of which 15.8 per cent readmissions were to a different hospital. The most common reason for readmission was infection (25.8%). Risk factors for 30-day readmission to any hospital include bowel resection, index admission at a for-profit hospital, Medicare, Medicaid, and Charlson Comorbidity Index ≥ 2. Risk factors for 30-day readmission to a different hospital include elective operation, drug abuse, discharge to a skilled nursing facility, and leaving against medical advice. The median cost of initial admission was higher in those who were readmitted ($16,560 [$10,805-$29,014] vs $11,752 [$8151-$17,724], P < 0.01). The median cost of readmission was also higher among those readmitted to a different hospital ($9826 [$5497-$19,139] vs $9227 [$5211-$16,817], P = 0.02). After UHR, one in six readmissions occur at a different hospital, have unique risk factors, and are costlier. Current hospital benchmarks fail to capture this subpopulation and, therefore, likely underestimate UHR readmissions.

Association of Sociodemographic Factors With Adherence to Age-Specific Guidelines for Asymptomatic Umbilical Hernia Repair in Children.

Importance: Current guidelines recommend delaying repair of asymptomatic umbilical hernia in children until after age 4 to 5 years to allow for spontaneous closure. Objective: To examine the association of sociodemographic factors with adherence to age-specific guidelines for asymptomatic umbilical hernia repair in children. Design, Setting, and Participants: In this multicenter retrospective cohort study, children 17 years and younger who underwent umbilical hernia repair from January 2013 to June 2018 at 47 freestanding children's hospitals participating in the Pediatric Health Information System database were eligible for study inclusion. Children who underwent multiple procedures, repair of recurrent hernias, or had missing sociodemographic data were excluded. Exposures: Early umbilical hernia repair was defined as repair at 3 years or younger. Emergent or urgent presentation was defined as repair performed during the same encounter or within 2 weeks of an emergency department visit, respectively. Patients were categorized by sex, race/ethnicity, insurance type, income quintile, and presence of complex chronic conditions. Main Outcomes and Measures: Multivariable mixed-effects logistic regression was used to evaluate the association of sociodemographic factors with the odds of early repair after adjusting for emergent or urgent presentation and hospital-level effects. Results: Of the 25 877 included children, 13 817 (53.4%) were female, 14 143 (54.7%) had public insurance, and the median (interquartile range) age was 5.0 (3.0-6.0) years. Following adjustment, increased odds of early repair was associated with public insurance (public vs commercial insurance: odds ratio [OR], 1.46; 95% CI, 1.36-1.56; P < .001), lower income (lowest vs highest income quintile: OR, 1.48; 95% CI, 1.33-1.65; P < .001), and female sex (female vs male sex: OR, 1.20; 95% CI, 1.13-1.27; P < .001). Children with public insurance in the lowest income quintile had 2.2-fold increased odds of early repair compared with children with commercial insurance in the highest income quintile (OR, 2.15; 95% CI, 1.93-2.40; P < .001). Sociodemographic factors were not associated with increased odds of early repair in the subgroup of children who underwent early repair following emergent or urgent presentation. Conclusions and Relevance: Public insurance, lower income, and female sex are independently associated with repair of asymptomatic umbilical hernias in children earlier than recommended by current guidelines. These children may be at greater risk of undergoing repair of umbilical hernias that may spontaneously close with further observation.

Assessment of early pulmonary function abnormalities in giant omphalocele survivors.

PURPOSE: Infants with giant omphalocele (GO) are at increased risk for persistent respiratory insufficiency, yet information regarding the systematic assessment of their lung function is limited. We performed a group of pulmonary function tests (PFTs) including spirometry, fractional lung volume measurements, assessment of bronchodilator responsiveness, and passive respiratory mechanics in GO survivors during infancy and early childhood to evaluate the nature and degree of pulmonary dysfunction. MATERIAL AND METHODS: Between July 2004 and June 2008, 30 consecutive GO survivors were enrolled in our interdisciplinary follow-up program. Forty-seven percent (14/30) underwent PFT during follow-up evaluation using the raised volume rapid thoracic compression technique to measure forced expiratory flows and bronchodilator responsiveness, body plethysmography to calculate lung volumes, and the single breath occlusion technique to measure passive mechanics of the respiratory system. RESULTS: The mean age at PFT assessment was 19.3 ± 19.7 months (range, 1.0-58). Mean forced vital capacity and mean forced expiratory volume in the first 0.5 second were significantly reduced compared with published normative values (P = .03 and P < .01, respectively). Total lung capacity was significantly reduced (P < .001), whereas functional residual capacity, residual volume, and residual volume to total lung capacity ratio were within the normative range (P = .21, P = .34, and P = .48, respectively). Among the 46% who demonstrated significant bronchodilator responsiveness, there were greater increases in the mean percentage changes in flow at 25% to 75% (P = .01), flow at 75% (P < .001), and flow at 85% (P < .001) compared with those participants that did not respond. Specific compliance was reduced, whereas specific conductance increased, compared with published normal results. CONCLUSIONS: Abnormalities of pulmonary function in GO survivors include lung volume restriction without airway obstruction, an increased likelihood of airway hyperresponsivness, and reduced respiratory system specific compliance. Early recognition of pulmonary functional impairment in GO survivors could help to develop targeted treatment strategies to reduce the risk of subsequent pulmonary morbidity.

Delayed management of giant omphalocele using silver sulfadiazine cream: an 18-year experience.

BACKGROUND/PURPOSE: To assess the value of topical silver sulfadiazine (SSD) cream in the treatment of babies with a giant omphalocele. METHODS: From 1991 to 2008 inclusive, 20 infants with giant omphalocele (defined as >10 cm diameter) were treated with SSD, leaving a large ventral hernia to be repaired at a later date. RESULTS: There were 12 boys and 8 girls. Thirteen had prenatal ultrasound diagnosis at a mean gestational age of 23 weeks. The mean gestational age at delivery was 37 weeks, and mean birth weight was 2.5 kg. Nineteen had other anomalies and/or medical problems, 18 of them multiple. The most common was pulmonary hypoplasia (70%). Mechanical ventilation and/or oxygen treatment was required in 15 (75%) for a mean of 10 weeks. SSD was used as primary sac treatment in 5 and secondary treatment in 15 (after Silon pouch 11, Op-site 3, povidone-iodine 1). Six omphalocele sacs were ruptured within the first 5 days of life. SSD was used for a mean of 6 months at a cost of $1 per day. Complications included 2 instances of staphylococcal sepsis and 1 jejunal perforation inside a Silon pouch. Six (30%) died from pulmonary hypoplasia at a mean age of 18 weeks. There were 14 (70%) survivors who went home after a mean of 14 weeks. Of the 14 survivors, 12 had ventral hernias repaired (18 operations with 2 recurrences), and 2 remain with their original ventral hernia. CONCLUSIONS: Initial topical coverage with SSD is associated with excellent outcomes for infants with giant omphalocele who cannot undergo immediate closure.

[Cost-effectiveness of hernia repair : IPOM versus open sublay mesh technique]. / Kosten- und Risikoanalyse der Hernienreparation : Laparoskopische IPOM- vs. offene Sublay-Technik.

In comparison to the conventional technique of incisional or umbilical hernia repair with sublay mesh augmentation, incisional hernias in obese patients can be surgically treated with minor surgical trauma by laparoscopic intraperitoneal onlay mesh (IPOM) repair. However, although shortened operation time, hospital stay and faster postoperative reconvalescence might be possible with IPOM repair, the economic calculation including mesh costs is significantly higher. In this study the two operation techniques were compared and the perioperative advantages and disadvantages of both methods were analyzed based on the German diagnosis-related groups (DRG) system.

[Congenital abdominal wall defects--an analysis of prevalence and operative management by means of gastroschisis and omphalocele]. / Ventrale Bauchwanddefekte--Darstellung der Entwicklung in Prävalenz und operativem Vorgehen anhand von Gastroschisis und Omphalozele.

The management of congenital abdominal wall defects is one of the main characteristics of quality for a department of paediatric surgery. The results of treatment in the early years were the reason for a continuous improvement of procedures, operation strategies and the kinds of -material that had been used. During the last years there has been a great discussion about the presumed increase in the incidence of gastroschisis and the preterm delivery of such cases. On the basis of our own first results (2006-2009) and details from the literature, we survey these two topics.

[Prosthetic mesh for hernia repair: which mesh for which indication? Analysis of the Committee for the Assessment of Devices and Health Technologies of the French National Authority for Health (HAS). Assessment of prosthetic meshes for hernia repair]. / Implants de réfection de paroi : lequel, dans quelle indication ? Analyse de la Commission d'évaluation des produits et prestations de la Haute Autorité de santé (HAS). Evaluation des implants de réfection de paroi.

UNLABELLED: The Committee for the Assessment of Devices and Health Technologies (CEPP), one of the specialist committees of the French National Authority for Health (HAS), reassessed the use of prosthetic mesh for hernia repair in 2008. Mesh use is reimbursed by French national health insurance for use in adult and pediatric surgery. This reassessment had two primary purposes: (a) to define the indications and clinical situations justifying the use of mesh, and to describe the technical requirements; (b) to define the conditions of prescriptions and of use and to contribute to decisions for the renewal of inscription. METHODS: We performed a systematic review of published data and manufacturers' licenses and applied the judgment of a multidisciplinary working group of involved healthcare professionals. The CEPP first analyzed the different sorts of prosthetic mesh according to operative indications; they then compared the performance of each prosthesis based on comparative data from the literature or based on expert opinion when there was no available comparative data. The committee recommended three types of prosthesis: flat patch mesh, three-dimensional mesh (plug), and double-sided patch. Additional studies were recommended to confirm the benefits of selected products. The cost of meshes has been integrated into the reimbursement of each Diagnostic Related Group (DRG) and is no longer included in the List of Reimbursable Products and Services (Liste des produits et prestations remboursables [LPPR]); the High Authority for Health (HAS) recommends the selection of those prostheses evaluated by the CEPP in order to optimize the quality and cost of health care.

Laparoscopic resorbable mesh fixation. Assessment of an innovative disposable instrument delivering resorbable fixation devices: I-Clip(TM). Final results of a prospective multicentre clinical trial.

BACKGROUND: The aim of this study was to assess the performance and tolerance of an innovative disposable instrument delivering resorbable clips (I-Clip, Sofradim, France) intended for mesh fixation in inguinal, incisional and umbilical hernias of the abdominal wall. The fixation device was designed to be resorbable in 1 year, with reduced trauma to the underlying tissues or the mesh, and with initial mechanical properties equivalent to those of conventional metal staples. METHODS: The study involved 105 patients with inguinal, umbilical or incisional hernias enrolled from 11 centres. Inguinal totally extra peritoneal (TEP) or trans abdomino pre-peritoneal (TAPP) repair was performed with Parietex mesh, incisional or umbilical hernias were treated via the intraperitoneal route with Parietex composite. I-Clips were used for mesh fixation in both indications according to the surgeon's habits. Efficacy was the principal assessment criteria evaluated by two parameters: quality of fixation evaluated subjectively at the time of procedure and recurrence rate according to the follow up at 1, 6 and 12 months. Pain evaluated by the patients using a visual analogue scale (VAS) was the principal secondary assessment criteria. Other tolerance criteria were also evaluated during surgery and follow up. RESULTS: The surgeons' evaluation of the fixation quality was assessed as good to very good in 100% of ventral hernias and good to very good in 85-92% of inguinal hernias. At 1 month, 90% of patients (94/104) were totally pain-free (VAS score: 0) and only ten patients reported low pain (VAS scores: 0.3-3.1). At 1 year, the pain described by those ten patients finally disappeared, 98% of patients (102/104) were totally pain-free. The rate of minor complications not related to the device concerned 5% of the patients at 1 month, which was reduced to 2% at one year and no recurrence or mesh sepsis was observed. CONCLUSIONS: The ease of use of this device, combined with the absence of recurrence related to the investigated device and the good pain-free outcome in this group of patients confirmed the effectiveness and tolerance of the resorbable fixation concept of I-Clip(TM).

Innovative and cost-effective management of large omphalocele.

BACKGROUND/PURPOSE: The aim of this study was to develop a method of management of large omphalocele, with easily available inexpensive materials. The efficacy of using the plastic of urine collection bag and paper stapler, in creating the "silo" for the management of 3 newborns with such defects, were assessed. METHODS: All operations were done within 36 hours of birth. A silo was created with the plastic of a sterile urine collection bag, which was stapled with a paper stapler at its free margin. The omphalocele was gradually reduced every 24 to 48 hours, using the stapler, until the contents were reduced, when the abdominal wall was repaired. RESULTS: The mean time taken to close the abdominal defect was 34 days. All patients could be breast-fed from 48 hours after the first stage is done. Rooming in was done by day 7. None of the babies required assisted ventilation. CONCLUSION: This method is simple and cost-effective, using minimally expensive, easily available materials.

Negative pressure wound therapy to treat peri-prosthetic methicillin-resistant Staphylococcus aureus infection after incisional herniorrhaphy. A case study and literature review.

The preferred treatment for incisional hernias occurring post laparotomy involves use of prosthetic mesh. If this mesh becomes infected, it may have to be removed to achieve wound healing. A patient with a methicillin-resistant Staphylococcus aureus-infected prosthetic mesh received negative pressure wound therapy to help facilitate healing without removing the prosthetic mesh applied to manage his hernia. After almost 4 weeks of treatment, the wound was closed secondarily. The literature contains many case studies about the use of NPWT for a variety of wounds but information about its safety and effectiveness for managing methicillin-resistant Staphylococcus aureus-infected prosthetic mesh is limited. The results of this case study add to the evidence that controlled clinical studies are warranted.

[Trocars and hernias: a simple, cheap remedy]. / Trocar ed ernie: un rimedio semplice ed economico.

Trocar-site incisional hernias and their complications are reported in 1% to 6% of patients. Such hernias are attributed to the difficulty of applying standard suturing techniques to wound closure. We report our experience with a simple device, the Deschamps ligature needle.

Assessment of obstructive apnea by using polysomnography and surgical treatment in patients with Beckwith-Wiedemann syndrome.

PURPOSE: Obstructive apnea is sometimes seen in patients with Beckwith-Wiedemann syndrome. The cause of apnea is not limited to macroglossia, and the surgical indication for obstructive apnea has not yet been established. The authors performed polysomnography for the assessment of apnea. METHOD: Overnight polysomnograms were obtained in 2 patients who developed obstructive apnea after 1-stage repair for omphalocele. CASE 1: Apnea index (AI), defined as apneic events per hour, indicated 17.3, and SpO2 below 95% occupied 80% of the total sleep time. Computed tomography and magnetic resonance imaging indicated obstruction of the airway between macroglossia and the hypopharynx. Central tongue resection and the division of the frenulum linguae for associated ankyloglossia were performed 97 days after birth. One month after surgery, apneic events disappeared and SpO2 below 95% occupied only 1% of the total sleep time. CASE 2: Obstructive AI indicated 28.1. Division of the frenulum linguae and anterior glossopexy were performed 55 days after birth. Postoperative polysomnogram indicated a marked reduction of AI. CONCLUSIONS: These results indicated that polysomnography was useful for evaluating obstructive apnea and that advancement of the tongue by division of the frenulum linguae may be recommended for the treatment of obstructive apnea in patients with Beckwith-Wiedemann syndrome.
