Background: Morgagni hernias are rare, with a reported incidence of 2% to 5% of congenital diaphragmatic hernias., Objectives: To review a laparoscopic technique to repair Morgagni hernias in pediatric patients., Methods: Retrospective chart review of pediatric patients who underwent minimally invasive repair of a Morgagni hernia from November 2009 to September 2017 within a defined population., Results: During an 8-year period, 15 patients with Morgagni hernias were identified. Four patients with Morgagni hernias were excluded because they had open repairs. Eleven Morgagni hernias were repaired through a completely minimally invasive approach. Three repairs were completed using a soft-tissue patch (Gore-Tex patch, W L Gore & Associates Inc, Flagstaff, AZ). All minimally invasive repairs were completed with transfascial sutures using an endoscopic suturing device (Endo Close, Covidien/Medtronic, Fridley, MN) and 2-0 nonabsorbable synthetic sutures with extracorporeal knot tying. Median follow-up was 40 months (range = 2.6 months to 7.3 years). No patients had postoperative pectus excavatum defects. There were no recurrences., Conclusion: Morgagni hernias are amenable to minimally invasive repair with this simple technique. With large defects, synthetic patches should be used. Recurrences are rare, and morbidity is low.

Context: Increasing popularity of strong magnets as toys has led to their ingestion by children, putting them at risk of potentially harmful gastrointestinal tract injuries., Objectives: To heighten physician awareness of the potential complications of magnetic foreign body ingestion, and to provide an updated algorithm for management of a patient who is suspected to have ingested magnets., Design: A retrospective review of magnet ingestions treated over a two-year period at our institutions in the Southern California Permanente Medical Group. Data including patient demographics, clinical information, radiologic images, and surgical records were used to propose a management strategy., Results: Five patients, aged 15 months to 18 years, presented with abdominal symptoms after magnet ingestion. Four of the 5 patients suffered serious complications, including bowel necrosis, perforation, fistula formation, and obstruction. All patients were successfully treated with laparoscopic-assisted exploration with or without endoscopy. Total days in the hospital averaged 5.2 days (range = 3 to 9 days). Average time to discharge following surgery was 4 days (range = 2 to 7 days). Ex vivo experimentation with toy magnetic beads were performed to reveal characteristics of the magnetic toys., Conclusions: Physicians should have a heightened sense of caution when treating a patient in whom magnetic foreign body ingestion is suspected, because of the potential gastrointestinal complications. An updated management strategy is proposed that both prevents delays in surgical care and avoids unnecessary surgical exploration.

Introduction: We conducted a study to determine whether hospital type (county [ie, safety-net] vs private) affects health care access (appendiceal perforation [AP] rates), treatment (laparoscopic appendectomy [LA] rates), and outcomes in children with appendicitis., Methods: A review of cases involving children who had appendicitis between 1998 and 2007 was performed. Data from county and private hospitals were compared. Outcomes were AP rates, LA rates, need for postoperative abscess drainage, length of hospitalization (LOH), and cost., Results: Multivariate analysis confirmed that among 7902 patients, (county = 682; private = 7220), county-hospital patients had lower incomes, higher AP rates, higher LA rates, lower postoperative abscess drainage rates, and longer LOH than did private-hospital patients. The longer LOH at the county institution led to higher costs. Within the county hospital, outcomes were similar across all ethnic groups and income levels., Conclusions: Children with appendicitis treated at a county hospital were of lower socioeconomic background and had higher AP rates, longer LOH, and higher costs than their counterparts at private hospitals, but were more likely to undergo LA and require less abscess drainage. Within the county hospital, ethnic and socioeconomic disparities were not apparent; thus, these differences between institutions might have been caused by underlying disparities in ethnicity, income, and health care access.

Background: Ultrasound guidelines for hypertrophic pyloric stenosis (HPS) have fixed minimum measurements and do not account for variation in patient weight or age. We sought to determine if preoperative pyloric measurements correlated with weight and age in patients with surgically proven HPS., Methods: A retrospective analysis was conducted of 189 patients with HPS treated at a single institution over a 5-year period (2005 to 2010). Pearson correlation and linear regression analyses were used to determine if there were statistically significant associations between these combinations of factors: age and pyloric muscle thickness, weight and pyloric muscle thickness, age and pyloric length, and weight and pyloric length., Results: Patients' mean age was 4.6 weeks (range, 1 to 17 weeks). Their mean weight was 3.9 kg (range, 2.5 to 8.0 kg). Mean pyloric muscle thickness was 0.42 cm (range, 0.18 to 0.86 cm), and mean pyloric length was 1.89 cm (range, 0.8 to 2.8 cm). Pearson correlation coefficient analysis showed a significant relationship between age and muscle thickness (r = 0.35, p < 0.001) as well as weight and muscle thickness (r = 0.24, p = 0.001). No significant relationship existed between pyloric length and age or weight. Linear regression analysis demonstrated similar results., Conclusion: In patients with HPS, pyloric muscle thickness was directly related to age and weight. Practitioners should be aware that smaller and younger infants with a clinical diagnosis of HPS may still truly have HPS even though the minimum diagnostic criterion for muscle thickness or length is not found on ultrasound.
