Robotic Repair of Congenital Paraesophageal Hiatal Hernia
Abstract Congenital paraesophageal hiatal hernias are rare and can be associated with gastric incarceration, volvulus, mucosal ulceration, and anemia. Primary repair of the hernia and fundoplication are recommended. In this paper, we report a case of a 3-year-old child with abdominal pain who was noted to have a paraesophageal hiatal hernia with partial gastric volvulus. A 5 mm robot platform was utilized to facilitate hernia sac dissection, hiatal repair, and fundoplication.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/63210/1/lap.2008.0185.pd
Morbidity and mortality of paediatric burns patients at Maputo Central Hospital, Mozambique
Background: The incidence of paediatric burn injuries is increasing in Africa. Paediatric burn injuries are among the leading causes of preventable morbidity and mortality in sub-Saharan Africa. Research on the morbidity and mortality in this setting is much needed.Methods: We conducted a prospective questionnaire-based analysis of paediatric burn patients presenting to the Maputo Central Hospital during a five-month period. Interviews were conducted with the children's caretakers by 2 paediatric surgery residents and 1 paediatrician at the Eduardo Mondlane Medical School in Maputo, with the aid of nursing staff.Results: Questionnaires were completed for 66 patients. Most burns occurred from scald injuries (n = 46), particularly from cooking (n = 27) and bathwater (n = 19), followed by fire injuries (n = 16). Burns occurred more frequently in the afternoon (n = 26) and morning (n = 23). Many patients reported no adult caretaker present at the time of the burn injury (n = 24). Most burns were grade II (n = 49). Nearly half of the patients received a blood transfusion (n = 30). One-third of the patients underwent operative surgical debridement (n = 21). Skin grafting was performed on a subset of these patients (n = 13). A large number of patients developed a wound infection (n = 39). All deaths occurred in patients who were admitted to the paediatric intensive care unit and had sepsis (n = 9). The mean total body surface area (TBSA) of burn deaths was 37% (range 20% to 50%), and many deaths were secondary to fire burns (6 of 9; 66.7%).Conclusions: Most paediatric burn injuries occur in association with domestic activities, such as cooking and bathing. Adult caretakers are frequently not present at the time of the burn injury. Mortality rates are high, especially for large body surface area burns caused by fire. Educational programmes may help reduce the incidence of burns and the associated morbidity and mortality. The improvement and expansion of emergency and intensive burn care services may help to improve survival.Keywords: burns; morbidity; mortality; paediatrics; paediatric surgery; Mozambiqu

Comparison of Outcomes of antibiotic Drugs and Appendectomy (CODA) trial: a protocol for the pragmatic randomised study of appendicitis treatment.
INTRODUCTION: Several European studies suggest that some patients with appendicitis can be treated safely with antibiotics. A portion of patients eventually undergo appendectomy within a year, with 10%-15% failing to respond in the initial period and a similar additional proportion with suspected recurrent episodes requiring appendectomy. Nearly all patients with appendicitis in the USA are still treated with surgery. A rigorous comparative effectiveness trial in the USA that is sufficiently large and pragmatic to incorporate usual variations in care and measures the patient experience is needed to determine whether antibiotics are as good as appendectomy.
OBJECTIVES: The Comparing Outcomes of Antibiotic Drugs and Appendectomy (CODA) trial for acute appendicitis aims to determine whether the antibiotic treatment strategy is non-inferior to appendectomy.
METHODS/ANALYSIS: CODA is a randomised, pragmatic non-inferiority trial that aims to recruit 1552 English-speaking and Spanish-speaking adults with imaging-confirmed appendicitis. Participants are randomised to appendectomy or 10 days of antibiotics (including an option for complete outpatient therapy). A total of 500 patients who decline randomisation but consent to follow-up will be included in a parallel observational cohort. The primary analytic outcome is quality of life (measured by the EuroQol five dimension index) at 4 weeks. Clinical adverse events, rate of eventual appendectomy, decisional regret, return to work/school, work productivity and healthcare utilisation will be compared. Planned exploratory analyses will identify subpopulations that may have a differential risk of eventual appendectomy in the antibiotic treatment arm.
ETHICS AND DISSEMINATION: This trial was approved by the University of Washington\u27s Human Subjects Division. Results from this trial will be presented in international conferences and published in peer-reviewed journals.

Analysis of Preoperative Factors for Time-Independent and Time-Dependent Outcomes
Preoperative factors can influence clinical practice and surgical outcomes. Awareness of these factors can facilitate the evaluation of risks and benefits of procedures, help counsel patients, and improve clinical guidelines. Statistical analysis must be tailored to the outcome of interest. In this thesis, two studies are used to illustrate the analysis of preoperative factors associated with the time-independent practice of blood transfusion administration and time-dependent complications of peritoneal dialysis
Robotic Extirpation of Complex Massive Esophageal Leiomyoma
ABSTRACT Esophageal leiomyomas are the most common benign mesenchymal esophageal tumors, but they occur rarely in the pediatric population. Leiomyomas are conventionally treated with extramucosal enucleation via an open thoracotomy. In this paper, we report a case of a complex massive retrocardiac esophageal leiomyoma that was successfully extirpated by using a robotic-assisted thoracoscopic technique. Intraoperative esophagoscopy and transillumination were useful adjuncts in identifying the esophagus and developing a safe extramucosal dissection plane.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/63380/1/lap.2007.0067.pd
In utero ileal volvulus and intestinal perforation associated with enteric duplication cyst presenting with preterm labour and acute abdomen in newborn
Enteric duplication cysts are a rare cause of intestinal obstruction in the neonatal period.

Methods of Conservative Antibiotic Treatment of Acute Uncomplicated Appendicitis
BackgroundMeta-analyses and a recent guideline acknowledge that conservative management of uncomplicated appendicitis with antibiotics can be successful for patients who wish to avoid surgery. However, guidance as to specific management does not exist.MethodsPUBMED and EMBASE search of trials describing methods of conservative treatment was conducted according to Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines.ResultsThirty-four studies involving 2,944 antibiotic-treated participants were identified. The greatest experience with conservative treatment is in persons 5 to 50 years of age. In most trials, imaging was used to confirm localized appendicitis without evidence of abscess, phlegmon, or tumor. Antibiotics regimens were generally consistent with intra-abdominal infection treatment guidelines and used for a total of 7 to 10 days. Approaches ranged from 3-day hospitalization on parenteral agents to same-day hospital or ED discharge of stable patients with outpatient oral antibiotics. Minimum time allowed before response was evaluated varied from 8 to 72 hours. Although pain was a common criterion for nonresponse and appendectomy, analgesic regimens were poorly described. Trials differed in use of other response indicators, that is, white blood cell count, C-reactive protein, and reimaging. Diet ranged from restriction for 48 hours to as tolerated. Initial response rates were generally greater than 90% and most participants improved by 24 to 48 hours, with no related severe sepsis or deaths. In most studies, appendectomy was recommended for recurrence; however, in several, patients had antibiotic retreatment with success.ConclusionWhile further investigation of conservative treatment is ongoing, patients considering this approach should be advised and managed according to study methods and related guidelines to promote informed shared decision-making and optimize their chance of similar outcomes as described in published trials. Future studies that address biases associated with enrollment and response evaluation, employ best-practice pain control and antibiotic selection, better define cancer risk, and explore longer time thresholds for response, minimized diet restriction and hospital stays, and antibiotic re-treatment will further our understanding of the potential effectiveness of conservative management.Level of evidenceSystematic review, level II
Malaria-associated peripheral gangrene
Malaria is a common parasitic disease endemic in tropical and subtropical areas, including Mozambique. Symmetrical peripheral gangrene is a rare complication of malaria. The purpose of this study was to review cases of malaria-associated peripheral gangrene that were evaluated by the pediatric surgical service at Hospital Central. Four patients ranging in age from 11 months to 7 years with documented Plasmodium falciparum infection and peripheral gangrene were identified. Amputation was required in cases of wet-gangrene. The majority of cases were allowed to self-demarcate, and one was allowed to auto-amputate

Global general pediatric surgery partnership: The UCLA-Mozambique experience.
Background/purposeThere has been increasing recognition of the disparities in surgical care throughout the world. Increasingly, efforts are being made to improve local infrastructure and training of surgeons in low-income settings. The purpose of this study was to review the first 5-years of a global academic pediatric general surgery partnership between UCLA and the Eduardo Mondlane University in Maputo, Mozambique.MethodsA mixed-methods approach was utilized to perform an ongoing needs assessment. A retrospective review of admission and operative logbooks was performed. Partnership activities were summarized.ResultsThe needs assessment identified several challenges including limited operative time, personnel, equipment, and resources. Review of logbooks identified a high frequency of burn admissions and colorectal procedures. Partnership activities focused on providing educational resources, on-site proctoring, training opportunities, and research collaboration.ConclusionThis study highlights the spectrum of disease and operative case volume of a referral center for general pediatric surgery in sub-Saharan Africa, and it provides a context for academic partnership activities to facilitate training and improve the quality of pediatric general surgical care in limited-resource settings.Level of evidenceLevel IV

Epidemiology of Disease and Mortality From a PICU in Mozambique.
ObjectivesDelivery of pediatric critical care in low-income countries is limited by a lack of infrastructure, resources, and providers. Few studies have analyzed the epidemiology of disease associated with a PICU in a low-income country. The aim of this study was to document the primary diagnoses and the associated mortality rates of patients presenting to a tertiary PICU in Mozambique in order to formulate quality improvement projects through an international academic partnership. We hypothesized that the PICU mortality rate would be high and that sepsis would be a common cause of death.DesignRetrospective, observational study.SettingTertiary academic PICU.PatientsAll admitted PICU patients.InterventionsAll available data collection forms containing demographic and clinical data of patients admitted to the PICU at Hospital Central de Maputo, Mozambique from January 2013 to December 2013 were analyzed retrospectively.Measurements and main resultsThe patient median age was 2 years (57% male). The most common primary diagnoses were malaria (22%), sepsis (18%), respiratory tract infections (12%), and trauma (6%). The mortality rate was 25%. Mortality rates were highest among patients with sepsis (59%), encephalopathy (56%), noninfectious CNS pathologies (33%), neoplastic diseases (33%), meningitis/encephalitis (29%), burns (26%), and cardiovascular pathologies (26%). The median length of PICU stay was 2 days. HIV exposure/infection had a nonstatistically significant association with mortality. Patients admitted for burns had the highest median length of PICU stay (4 d). Most trauma admissions were male (75%), and approximately half of all trauma admissions had an associated head injury (55%).ConclusionsInfectious disease and trauma were highly represented in this Mozambican PICU, and overall mortality was high compared with high-income countries. With this knowledge, targeted collaborative projects in Mozambique can now be created and modified. Further research is needed to monitor the potential benefits of such interventions
