  • Single-Institution Financial Analysis of Biologic Versus Synthetic Mesh Hernia Repair: A Retrospective Analysis of Patients Readmitted for Hernia Repair. Annals of plastic surgery Otake, L. R., Satterwhite, T., Echo, A., Chiou, G., Lee, G. K. 2013

    Abstract

    The advent and proliferation of commercially available biologic mesh material has expanded the repertoire of hernia repair materials available to the surgeon. Given the higher initial cost of these mesh materials relative to synthetic materials such as polypropylene, there has been debate regarding the purported benefit of the use of biologic mesh. This study is a single-institution review of complex hernia repairs using both biologic and synthetic mesh materials. The patients included in the analyses were admitted to the institution at least twice for management of hernia; this permitted specific evaluation of a given diagnosis, hernia, in the same patient, but at different points in time. In a subset of patients, hernia repair was performed upon the second admission with conversion from biologic or synthetic mesh, which had been placed at the initial repair. The objective of this study was to evaluate the financial implications of mesh choice. Specific parameters reviewed included type of mesh used, total costs of hospitalization, direct cost associated with the hernia repair, total collections, and percentage of collections relative to total charges. Through such analysis, our aim was to determine whether there were any variances in revenue and costs associated with the application of either mesh material or the associated clinical scenarios.

  • Concurrent Laparoscopic Morgagni Hernia Repair and Sleeve Gastrectomy JOURNAL OF LAPAROENDOSCOPIC & ADVANCED SURGICAL TECHNIQUES Chiou, G., Tedesco, M., Eisenberg, D. 2012; 22 (10): 999-1002

    Abstract

    The Morgagni-type anterior diaphragmatic hernia is a congenital defect that is a very uncommon hernia presenting in an adult. Surgical repair is usually recommended upon diagnosis and often requires synthetic mesh for a durable, tension-free repair. The use of synthetic mesh concurrently with several of bariatric operations is controversial owing to the potential for mesh infection. In this report we describe a laparoscopic repair of a symptomatic Morgagni hernia with synthetic mesh, concurrently with sleeve gastrectomy, in a morbidly obese man. The patient was a 58-year-old man with a body mass index of 48 kg/m(2) and associated co-morbid conditions that included obstructive sleep apnea, hypertension, hyperlipidemia, impaired fasting glucose, and osteoarthritis. He was diagnosed with Morgagni hernia with exertional dyspnia. He underwent concurrent laparoscopic Morgagni hernia repair with mesh and sleeve gastrectomy. At 2 months after surgery the patient was doing well and tolerating solid foods, and his percentage excess weight loss was 35%. He was exercising regularly and had no exertional dyspnea. Laparoscopy is an attractive approach to performing multiple intra-abdominal procedures concurrently. The Morgagni hernia repair with mesh can be performed safely and effectively using a laparoscopic approach. This can be performed concurrently with bariatric surgery in the morbidly obese.

  • Magnetic Resonance Imaging for Detection of Brain Abnormalities in Fetuses With Cleft Lip and/or Cleft Palate CLEFT PALATE-CRANIOFACIAL JOURNAL Rosen, H., Chiou, G. J., Stoler, J. M., Mulliken, J. B., Tarui, T., Meara, J. G., Estroff, J. A. 2011; 48 (5): 619-622

    Abstract

    To determine the prevalence of brain abnormalities identified by prenatal imaging of fetuses with cleft lip with or without cleft palate (CL/P) or cleft palate only (CP) and to compare with postnatal imaging and neurologic evaluation.This was a retrospective review of radiologic images (magnetic resonance imaging [MRI] and sonography) of fetuses diagnosed with CL/P or CP at the Advanced Fetal Care Center at Children's Hospital Boston between 2002 and 2008. Images were reviewed for possible brain abnormalities by a pediatric radiologist who specializes in this field. Postnatal imaging was also assessed whenever available and correlated with clinical findings.A large, tertiary-care, academic pediatric hospital.One hundred twenty-six fetuses and 105 corresponding infants.Brain abnormalities were found in 8 of 126 fetuses (6.3%) by prenatal MRI. The malformations were corpus callosal dysgenesis (n = 3), encephalocele (n = 1), hypoplasia of the cerebellar hemispheres or vermis (n = 3), and white matter neuronal migration anomaly (n = 1). An additional 2 patients were diagnosed with brain abnormalities postnatally that had not been detected on prenatal imaging.The possibility of brain anomalies should be assessed in a fetus found to have CL/P or CP by sonography and/or MRI. Central nervous system imaging and careful neurodevelopmental follow-up is indicated in these infants.

  • Two Routine Blood Tests-Mean Corpuscular Volume and Aspartate Aminotransferase-as Predictors of Delirium Tremens in Trauma Patients JOURNAL OF TRAUMA-INJURY INFECTION AND CRITICAL CARE Findley, J. K., Park, L. T., Siefert, C. J., Chiou, G. J., Lancaster, R. T., deMoya, M., Gervasini, A., Velmahos, G. C. 2010; 69 (1): 199-201

    Abstract

    Delirium tremens (DT) in trauma patients is associated with significant morbidity and mortality. Short interview tools have been used to determine the risk of DT but require an alert, compliant patient and a motivated physician. The mean corpuscular volume (MCV) and aspartate aminotransferase (AST) levels are parts of routine laboratory testing, influenced by excessive alcohol consumption, and may serve as predictors of DT. This study examines the predictive ability of these two readily available biological markers.The records of 423 consecutive trauma patients who presented to a Level I trauma center with a positive toxicology screen for alcohol were reviewed. The outcome variable was DT, as defined by the presence of tremor, diaphoresis, autonomic instability, and hallucinations. The positive predictive value (PPV), negative predictive value (NPV), and likelihood ratio (LR) of the admission MCV and AST values were calculated for the prediction of DT.Of the 336 patients who met the criteria for study participation, 110 were diagnosed with DT due to alcohol withdrawal. When the admission MCV and AST were normal, only 3 patients (3.8%) developed DT. The NPV, PPV, and LR with two normal values together were 58.2%, 3.8%, and 0.080, respectively. When both were abnormal, 72 patients (64.3%) developed DT. The NPV, PPV, and LR with two abnormal values together were 83%, 64.3%, and 3.698, respectively.Normal admission MCV and AST values in intoxicated trauma patients nearly exclude the development of DT.
