Purpose Rapid sequence intubation (RSI) drugs, such as propofol, affect clinical outcomes, but this has not been examined in the pediatric population. This descriptive study compares the outcomes associated with intubation drugs used in pediatric traumatic brain injury (TBI) patients. Methods A retrospective chart review and descriptive analysis of intubated TBI patients, ages 0–17, admitted to Children's Hospital London Health Sciences Centre (LHSC) from January 2006–December 2016 was performed. Results Out of 259 patients intubated, complete data was available for 107 cases. Average injury severity score was 28; 46 were intubated at LHSC, 55 at primary care site, and 6 on scene. Intubation attempts were recorded in 87 of 107 paper charts. First-pass intubation success rate was 88.5%. Propofol (n = 21), midazolam (n = 31), etomidate (n = 13), and ketamine (n = 7) were the most commonly used intubation drugs. Paralytics were used in 50% of patients. Following use of propofol, Pediatric Adjusted Shock Index was increased as a result of worsening hypotension. Mean total hospital length of stay was 21 days with 7.5 days in ICU. Survival was 87%. Conclusion Great variability exists in the use of induction agents and paralytics for RSI. Propofol was commonly used and is potentially associated with poorer clinical outcomes. Type of Study Retrospective. Level of Evidence IV

Solid pseudopapillary tumour is a rare carcinoma of the pancreas with low-grade malignant potential that typically presents in females in their third decade. The tumour most commonly occurs in the tail of the pancreas, although any site can be affected. Surgical resection is the standard treatment and offers an excellent prognosis. Robotic-assisted laparoscopic surgery is an emerging technique for the treatment of pancreatic neoplasms. We report a case of a 17-year-old female with acute onset abdominal pain who was found to have a mass in the distal pancreas. A robotic-assisted laparoscopic distal pancreatectomy with spleen preservation was successfully performed, its first reported use in a pediatric patient. The patient had an uncomplicated recovery. The robotic approach can be considered for younger patients presenting with a solid pseudopapillary tumour in the distal pancreas.

Given that the management of severely injured children requires coordinated care provided by multiple pediatric surgical subspecialties, we sought to describe the frequency and associated costs of surgical intervention among pediatric trauma patients admitted to a level 1 trauma centre in southwestern Ontario.All pediatric (age18 yr) trauma patients treated at the Children's Hospital - London Health Sciences Centre (CH-LHSC) between 2002 and 2013 were included in this study. We compared patients undergoing surgical intervention with a nonsurgical group with respect to demographic characteristics and outcomes. Hospital-associated costs were calculated only for the surgical group.Of 784 injured children, 258 (33%) required surgery, 40% of whom underwent orthopedic interventions. These patients were older and more severely injured, and they had longer lengths of stay than their nonsurgical counterparts. There was no difference in mortality between the groups. Seventy-four surgical patients required intervention within 4 hours of admission; 45% of them required neurosurgical intervention. The median cost of hospitalization was $27 571 for the surgical group.One-third of pediatric trauma patients required surgical intervention, of whom one-third required intervention within 4 hours of arrival. Despite the associated costs, the surgical treatment of children was associated with comparable mortality to nonsurgical treatment of less severely injured patients. This study represents the most recent update to the per patient cost for surgically treated pediatric trauma patients in Ontario, Canada, and helps to highlight the multispecialty care needed for the management of injured children.La prise en charge des enfants grièvement blessés nécessite la coordination des soins fournis dans le contexte de plusieurs surspécialités chirurgicales pédiatriques. Dans ce contexte, nous avons cherché à décrire la fréquence et les coûts des interventions chirurgicales chez les patients pédiatriques victimes de trauma admis dans un centre de traumatologie de niveau 1 dans le sud-ouest de l'Ontario.Tous les patients pédiatriques (moins de 18 ans) ayant subi un trauma traités à l'Hôpital pour enfants du Centre des sciences de la santé de London entre 2002 et 2013 ont été retenus pour l'étude. Nous avons comparé les caractéristiques démographiques et les résultats cliniques des patients ayant subi une intervention chirurgicale et de ceux n'en ayant pas subi. Les coûts d'hospitalisation n'ont été calculés que pour le premier groupe.Parmi les 784 enfants à l'étude, 258 (33 %) avaient eu besoin d'une intervention chirurgicale; 40 % de ceux-ci avaient subi des interventions orthopédiques. Ces patients étaient plus âgés et plus grièvement blessés que les enfants n'ayant pas subi d'intervention chirurgicale, et leur séjour à l'hôpital était généralement plus long. Nous n'avons relevé aucune différence entre les 2 groupes quant à la mortalité. En outre, 74 des patients ayant subi une intervention chirurgicale ont dû être opérés dans les 4 heures suivant l'admission; 45 % d'entre eux ont eu besoin d'une intervention neurochirurgicale. Le coût médian d'une hospitalisation était de 27 571 $.Le tiers des patients pédiatriques victimes de trauma ont eu besoin d'une intervention chirurgicale, et le tiers de ceux-ci ont dû être opérés dans les 4 heures suivant leur arrivée. Malgré les coûts, le traitement chirurgical des enfants était associé à un taux de mortalité comparable à celui du traitement non chirurgical des patients blessés moins grièvement. Cette étude est la source d'information la plus récente sur le coût par patient associé au traitement chirurgical des enfants victimes de trauma en Ontario, et elle met en évidence le besoin de soins de multiples spécialités.

Despite the introduction of robotic surgery in 2000, few pediatric surgeons outside the United States have embraced this technology. We discuss our experience with establishing the first Canadian pediatric robotic surgery program. After simulator training, live animal surgery and observation of robotically assisted cases at an outside institution, we performed our first pediatric da Vinci® surgery in July 2013. A prospective database was established to assess outcomes. Forty one children have undergone robotically assisted surgery for the following 42 procedures: (a) pyeloplasty (17), (b) ureteral reimplantations (12), (c) uretero-uretostomy (1), (d) cholecystectomies (10), (e) interval appendectomy (1) and (f) distal pancreatectomy (1). The average age was 9.7 years (range 1.6-17.9) and 66% of patients were female. Average operative time was 174 min (range 47-301). Length of stay was 3 days (range 0-20). All procedures were completed without conversion to open or laparoscopy. There were no technical failures. Two post re-implantation patients had urine leaks which required conservative treatment. Despite the lack of haptic feedback, we have noted that the markedly enhanced three-dimensional visualization and instrument dexterity offer significant advantages for complex reconstructive pediatric surgery. This platform may also enable trainees to perform more advanced minimally invasive pediatric surgery. We have successfully established the first pediatric robotic surgery program in Canada. Our da Vinci® system is shared with our adult colleagues, which enables more frequent use as well as some cost sharing. A dedicated group of operative nurses and surgeons are required to allow adoption of this new technology.

BACKGROUND: The London Health Sciences Centre Home Safety Program (HSP) provides safety devices, education, a safety video, and home safety checklist to all first-time parents for the reduction of childhood home injuries. The objective of this study was to evaluate the HSP for the prevention of home injuries in children up to 2 years of age. METHODS: A program evaluation was performed with follow-up survey, along with an interrupted time series analysis of emergency department (ED) visits for home injuries 5 years before (2007–2013) and 2 years after (2013–2015) implementation. Spatial analysis of ED visits was undertaken to assess differences in home injury rates by dissemination areas controlling differences in socioeconomic status (i.e., income, education, and lone-parent status) at the neighborhood level. RESULTS: A total of 3,458 first-time parents participated in the HSP (a 74% compliance rate). Of these, 20% (n = 696) of parents responded to our questionnaire, with 94% reporting the program to be useful (median, 6; interquartile range,2 on a 7-point Likert scale) and 81% learning new strategies for preventing home injuries. The median age of the respondent's babies were 12 months (interquartile range, 1). The home safety check list was used by 87% of respondents to identify hazards in their home, with 95% taking action to minimize the risk. The time series analysis demonstrated a significant decline in ED visits for home injuries in toddlers younger than2 years of age after HSP implementation. The declines in ED visits for home injuries remained significant over and above each socioeconomic status covariate. CONCLUSION: Removing hazards, supervision, and installing safety devices are key facilitators in the reduction of home injuries. Parents found the HSP useful to identify hazards, learn new strategies, build confidence, and provide safety products. Initial finding suggests that the program is effective in reducing home injuries in children up to 2 years of age

There is ongoing variation in the use of video-assisted thoracoscopic surgery (VATS) and chest tube with fibrinolytics (CTWF) for empyema in children. Our objective was to report outcomes from a centre that recently made the transition from VATS to CTWF as the primary treatment modality.We conducted a historical cohort study of children with empyema treated with either primary VATS (between 2005 and 2009) or CTWF (between 2009 and 2013).Sixty-seven children underwent pleural drainage for empyema during the study period: 28 (42%) were treated with primary VATS, and 39 (58%) underwent CTWF. There were no significant differences between the VATS and CTWF groups for length of stay (8 v. 9 d, p = 0.61) or need for additional procedures (4% v. 13%, p = 0.19). Length of stay varied widely for both VATS (4-53 d) and CTWF (5-46 d). Primary VATS failed in 1 (4%) patient, who required an additional chest tube, and CTWF failed in 5 (13%) patients. Additional procedures included 3 rescue VATS, 2 additional chest tubes and 1 thoracotomy. All patients recovered and were discharged home.Primary VATS and CTWF were associated with similar outcomes in children with empyema. There appears to be a subset of children at risk for treatment failure with CTWF. Further research is needed to determine if these patients would benefit from primary VATS.Il existe une certaine variation dans le choix de l'intervention chirurgicale thoracoscopique assistée par vidéo (CTAV) ou de l'installation d'un drain thoracique accompagné de fibrinolytiques (DTIF) pour traiter la pleurésie purulente chez les enfants. L'objectif de cette étude était de décrire les résultats observés dans un centre ayant récemment remplacé la CTAV par le DTIF comme traitement de première intention.Nous avons mené une étude de cohorte rétrospective auprès d'enfants atteints de pleurésie purulente, qui ont été traités soit par CTAV (entre 2005 et 2009), soit par l'installation d'un DTIF (entre 2009 et 2013).Pendant la période à l'étude, 67 enfants ont subi un drainage pleural. De ce nombre, 28 (42 %) ont été traités par CTAV, et 39 (58 %) par DTIF. Aucune différence significative n'a été observée entre ces 2 groupes sur le plan de la durée du séjour (8 j. [CTAV] contre 9 j. [DTIF],La CTAV et le DTIF employés comme traitements de première intention sont associés à des résultats semblables chez les enfants atteints de pleurésie purulente, mais l'installation d'un DTIF semble être plus susceptible d'échouer chez un sous-ensemble d'enfants. D'autres recherches seront nécessaires pour déterminer s'il serait préférable d'avoir recours à la CTAV comme traitement de première intention.

The objective of our study was to identify the most common mechanisms of injury leading to death in our pediatric population.A retrospective cohort of fatally injured children 0-17 years old treated at our trauma center during 2000-2015.The mortality rate in our population was 8% (n = 103). Fifty-five percent were male. The majority (76%) of fatal injuries were blunt. Overall, motor vehicle collisions (MVCs) were the most common mechanism of injury (61%), followed by assault/abuse (9%). Of the deaths caused by MVCs, 37 (59%) were occupants, 11 (17%) were pedestrians, and 6 (10%) were cyclists. In the infant sub-population, assault/abuse was the most common mechanism of injury.MVCs were the leading cause of death in this population. In the infant subpopulation (1 year), abusive head trauma emerged as the leading mechanism. Injury prevention programming should target abusive head trauma in infants and teen road safety.

Objectives The purpose of this study was to quantify the incidence, patient profile, and outcomes associated with massive transfusion in paediatric trauma patients prior to establishing a massive transfusion protocol. Methods We performed a retrospective review of paediatric trauma patients treated at London Heath Sciences Centre between January 1, 2006, and December 31, 2011. Inclusion criteria were Injury Severity Score (ISS) greater than 12 and age less than 18 years. Results 435 patients met the inclusion criteria. Three hundred and fifty-six (82%) did not receive packed red blood cells in the first 24 h, 66 (15%) received a non-massive transfusion ( 40 mL/kg). Coagulopathy of any kind was more common in massive transfusion (11/13; 85%) than non-massive (32/66; 49%) (p = 0.037). Hyperkalemia (18% versus 23%; p = 0.98) and hypocalcemia (41% versus 46%; p = 1.00) were similar in both groups. Of the 13 massively transfused patients, 9 had multisystem injuries due to a motor vehicle collision, 3 had non-accidental head injuries requiring surgical evacuation, and 1 had multiple stab wounds. In the absence of a massive transfusion protocol, only 8 of the 13 patients received both fresh frozen plasma and platelets in the first 24 h. Massive transfusion occurred in patients from across the age spectrum and was associated with severe injuries (mean ISS = 33), a higher incidence of severe head injuries (92%), longer hospital stay (mean = 36 days), and increased mortality (38%). Conclusions This study is the first to describe the incidence, complications, and outcomes associated with massive transfusion in paediatric trauma patients prior to a massive transfusion protocol. Massive transfusion occurred in 3% of patients and was associated with coagulopathy and poor outcomes. Protocols are needed to ensure that resuscitation occurs in a coordinated fashion and that patients are given appropriate amounts of fresh frozen plasma, platelets, and cryoprecipitate.

The purpose of this study was to determine if early, acute appendicitis in children can be safely and effectively managed with antibiotics alone.A retrospective review was performed of children (18 yrs) treated non-operatively (NOM) for early, acute appendicitis since May 2012. These were compared to patients treated with appendectomy between January 2011 and October 2011 (OM). Inclusion criteria included: (a) symptoms48 h, (b) localized peritonitis, and (c) ultrasound findings consistent with early, acute appendicitis.Twelve patients (66% female, mean age 12.2,SD=4.2 yrs) were treated non-operatively, while 12 (50% female, mean age 12.5,SD=3.2 yrs) were treated operatively. Two NOM children (16.7%) required initial appendectomy. One patient developed recurrent appendicitis requiring appendectomy 7 months post-discharge. Four other NOM patients returned with symptoms but did not require admission or surgery. Two OM patients (8.3%) had hospital visits and admissions related to surgical site infections. Mean length of stay (LOS) for the first visit was 1.5 days (SD=1.0d) (NOM) vs. 1.3 days (SD=0.5d) (OM) (p=0.61). Including first and subsequent admissions, mean LOS was 1.8 days (SD=1.1d) (NOM) vs. 1.7 days (SD=1.5d) (OM) (p=0.97).Early acute appendicitis in appropriately selected children can be successfully treated non-operatively. Randomized trials with longer follow-up are required.

Background Severely injured pediatric trauma patients often present to hospital with early coagulopathy and metabolic acidosis. These derangements are associated with poor outcomes, but it is unclear to what degree they predict transfusion of packed red blood cells (pRBC). Methods We retrospectively identified pediatric trauma patients from a level 1 trauma center from 2006 to 2013. Inclusion criteria were age less than 18years, Injury Severity Score greater than 12, and pRBC transfusion within 24h of admission. Results We identified 96 pediatric trauma patients who underwent pRBC transfusion within 24h of presentation to hospital. On admission, 43% of these patients had one or more signs of coagulopathy, and 81% had metabolic acidosis. Size of pRBC transfusion in the first 24h ranged from 3 to 177mL/kg (mean 29mL/kg), and nineteen patients (20%) underwent massive transfusion (>40ml/kg in 24h). Univariate analysis indicated that size of pRBC transfusion was associated with initial base excess (r=0.46), international normalized ratio (r=0.35), partial thromboplastin time (r=0.41), fibrinogen (r=0.46), and BIG score (Base deficit, INR, Glasgow Coma Scale (GCS), r=0.36). Platelet count, age, GCS, and direct versus referred presentation were not predictive. Multivariable linear regression confirmed that coagulopathy and metabolic acidosis remained predictive after adjusting for direct versus referred presentation (R 2 =0.30). Conclusions Early coagulopathy and metabolic acidosis predict size of pRBC transfusion among pediatric trauma patients. Further research is needed to develop massive transfusion protocols and guidelines for activation.

We report a case of a child with a right ventricular inflammatory myofibroblastic tumor (IMT) who presented with fever, viral symptoms, and abdominal discomfort. Including this case, 49 intracardiac tumors have been previously reported in all age groups. The majority of intracardiac IMTs occur in pediatric patients, with approximately half presenting in children aged

The Impact program is an adolescent, injury prevention program with both school- and hospital-based components aimed at decreasing high-risk behaviors and preventing injury. The objective of this study was to obtain student input on the school-based component of Impact, as part of the program evaluation and redesign process, to ensure that the program content and format were optimal and relevant, addressing injury-related issues important for youth in our region.Secondary schools were selected in various geographic regions with students varying in language, religion, and socioeconomic status. A mixed-methods questionnaire was developed and pretested on program content, format, relevance, quality, and effectiveness. Attitude and opinion questions on issues facing teens today were ranked on a 7-point Likert scale. Open-ended, qualitative questions were included in the focus groups, with responses themed.There were 167 respondents in the nine geographically, socioeconomically, and culturally diverse focus groups with a mean age of 16 years, 52% were male, and 69% were in Grade 11. Ninety-three percent of respondents rated the content of Impact as comprehensive (median, 6 of 7, with 7 being very comprehensive), and 29% rated the format a 5 of 7. Impact was rated relevant (89%), addressing issues for teens (median, 6 of 7). Issues suggested to highlight included texting and driving, drugs, partying, self-harm, and abusive relationships. Texting while driving was perceived as a significantly more common (81%) injury issue for adolescents compared with other driving risk factors (p0.001), with one student commenting, "If you don't (text and drive), you either don't have a phone or don't have a driver's license."Injury prevention programs must be continually evaluated to ensure they are relevant, addressing issues important for youth, and presented in a format that resonates with the audience. Student focus groups identified motor vehicle collisions and texting as important issues as well as a desire for teens to hear personal stories with a visual element. This provided the information needed to develop the next logical direction for our program, the production of a distracted driving video ("Distracted Driving: Josh's Story," http://youtu.be/BFPke9gBybc) to be incorporated into school presentations.Epidemiologic/prognostic study, level III.

This study describes our experience with the placement of a skin-level gastrostomy device (MIC-KEY) in a single procedure.We identified infants, children and young adults who underwent laparoscopic-assisted percutaneous endoscopic gastrostomy (LAPEG) tube insertion between October 2009 and June 2013. The steps of this procedure include upper endoscopy, single-port laparoscopy, gastropexy via percutaneous T-fasteners and placement of a skin-level gastrostomy device (MIC-KEY) using a "push" technique with a tear-away sheath.We included 92 patients in our study. Mean age was 3.7 years (range 3 wk-5 yr), and mean weight was 11.2 (range 2.8-54) kg. Median procedural time was 20 (range 12-76) minutes. Total median duration for the most recent 25 procedures was lower than that of the first 25 (62 v. 79 min, p = 0.004). There were no intraoperative complications or conversions to open surgery. Postoperative complications were observed in 6 (6.5%) patients. Three retained T-fasteners were assessed endoscopically (n = 1) or removed via local excision (n = 2). Two patients experienced early dislodged feeding tubes that were replaced via interventional radiology (n = 1) or repeat LAPEG (n = 1). There was also 1 intra-abdominal fluid collection that was drained percutaneously but ultimately required a laparotomy and washout. There were no major complications in the most recent 50 procedures.Our results suggest that LAPEG is a safe, minimally invasive procedure for infants, children and young adults. This approach allows for immediate use of a skin-level gastrostomy device without the need for postoperative tube exchanges.Cette étude décrit notre expérience avec la pose d’un dispositif de gastrostomie au niveau de la peau (MIC-KEY) en une seule intervention.Nous avons recensé les nourrissons, enfants et jeunes adultes ayant subi l’insertion d’un tube de gastrostomie par voie endoscopique percutanée sous laparoscopie (GEPL) entre octobre 2009 et juin 2013. Les étapes de cette intervention incluent une endoscopie haute, une laparoscopie à trocart unique, une gastropexie avec ancres en T percutanées et la pose d’un dispositif de gastrostomie au niveau de la peau (MIC-KEY) à l’aide de la technique « push » et d’une pellicule amovible.Nous avons inclus 92 patients dans notre étude. L’âge moyen était de 3,7 ans (de 3 semaines à 5 ans) et le poids moyen était de 11,2 (de 2,8 à 54) kg. La durée médiane de l’intervention a été de 20 minutes (entre 12 et 76 minutes). La durée totale médiane des 25 plus récentes interventions a été plus brève que celle des 25 premières (62 c. 79 minutes, p = 0,004). On n’a observé aucune complication peropératoire ni conversion vers une chirurgie ouverte. Des complications postopératoires ont été observées chez 6 (6,5 %) patients. Trois ancres en T persistantes ont été évaluées par voie endoscopique (Selon nos résultats, la GEPL est une intervention sécuritaire et minimalement effractive pour les nourrissons, les enfants et les jeunes adultes. Cette approche permet l’utilisation immédiate d’un dispositif de gastrostomie au niveau de la peau sans nécessiter de changements de sondes après l’intervention.

Pilonidal disease is a chronic, acquired inflammatory process of the skin due to entrapped hair at the natal cleft. Reported recurrence rates are as high as 30%, and recurrence has been attributed to persistent hair near the surgical site. Although conservative measures, such as meticulous hair control and improved perineal hygiene, have been shown to be effective, these techniques typically require much effort on behalf of the patient. Laser hair epilation (LE) might solve this issue of poor patient compliance while helping patients to avoid surgical excision. In this article, we discuss recurrence rates of pilonidal disease in children treated with LE versus surgical excision in relation to findings from our institution between 2005 and 2013 as well as patient satisfaction with the treatment method.

Ectopic ACTH syndrome is a rare but important cause of pediatric Cushing syndrome, for which management by a multidisciplinary team is required. Although diagnostic evaluation is similar to that in adults, the variation in epidemiology may sway investigations, leading to inappropriate and/or incomplete diagnostic interventions. We present a case of 15-year-old girl with symptoms of severe ACTH-dependent Cushing syndrome and two pituitary adenomas. The ectopic source of ACTH production was confirmed after petrosal venous sampling was performed. Diagnostics and perioperative management of a pulmonary carcinoid tumor producing ectopic ACTH is reviewed. In pediatric patients, as in adult patients, a pituitary lesion

The objective of this study was to evaluate the use of analgesia in the resuscitative phase of severely injured children and adolescents.A retrospective cohort of paediatric (age18 years), severely injured (ISS≥12) patients were identified from the London Health Sciences Centre's Trauma Registry from 2007 to 2010. Variables were compared between Analgesia and Non-analgesia groups with Pearson Chi-square and Mann-Whitney U tests. Resuscitative analgesia use was assessed through multivariable logistic regression controlling for age, gender, mechanism, arrival and Trauma Team Activation (TTA).Analgesia was used in 32% of cases. Univariate analysis did not reveal any differences in gender, age, injury type, injury profile and arrival patterns. Significant differences were found with analgesia used more frequently in patients injured in a motor vehicle collision (58% vs. 42%, p=0.026) and having parents in the resuscitation room (17% vs. 6%, p=0.01). Analgesia patients were more injured (median ISS 22 vs. 17, p=0.027) and had 2.25 times more TTA (39% vs. 17%). Logistic regression revealed patients arriving directly to a trauma centre had a higher incidence of receiving analgesia (OR 2.01, 95% CI: 1.03-3.93), as did TTA (OR 2.18, 95% CI: 1.01-4.73) and having parents in resuscitation room (3.56, 95% CI: 1.23-10.33). Narcotics were most commonly used (85%), followed by benzodiazepines (16%), with 66% given during the primary survey.Use of analgesia is important in the acute management of paediatric trauma. Direct presentation to a level I trauma centre, TTA and the presence of parents lead to higher appropriate use of analgesia in paediatric trauma resuscitation.

Beckwith-Wiedemann syndrome (BWS) is an imprinting disorder characterized by overgrowth, congenital malformation, and tumor predisposition. Children with BWS have a higher incidence of tumors, commonly intra-abdominal tumors such as Wilms tumor, hepatoblastoma, and adrenal cortical carcinoma. Here, we describe the first case of a rare hepatic malignancy of nested stromal epithelial tumor (NSET) of the liver in a child with BWS. A 22-month old girl with BWS had a new incidental liver mass. Her alpha-fetoprotein levels were normal. She underwent a liver segmentectomy. Histopathologic features combined with immunohistochemistry results (positivity for pankeratin [AE1/3], CD56, CK19, CD117, CD99 [weak membranous pattern], β-catenin, and WT1-COOH [focal]), were diagnostic of NSET of the liver. This is the first case of NSET of the liver associated with BWS. Its occurrence at such an early age is consistent with the tumor predisposition of BWS.

Background First described in the pediatric population in 1899 by Oltmann, pediatric gastric volvulus is a rare disease, but carries a high mortality rate. Due to vague signs and symptoms it can easily be mistaken for gastroenteritis or appendicitis, but unique radiographic findings can help illuminate the diagnosis. The pathophysiology of gastric volvulus is related to an abnormality in the attachment of at least one of the gastric ligaments, which can occur either primarily or secondarily. The abnormality in these ligaments allows the stomach to freely rotate, eventually causing an obstruction. We describe a unique case occurring in a 6-year-old with no pre-exiting medical conditions as well as the associated radiographic images. Objectives Our aim is to discuss the presentation and management of a potentially lethal intra-abdominal process that mimics far more benign disease entities and to highlight the pertinent radiographic findings. Case Report A previously healthy 6-year-old female presented to the emergency department in the middle of the night after sudden onset of vomiting and abdominal pain. On exam her heart rate was mildly elevated but all other vital signs were within normal limits. She was assessed with an abdominal x-ray and given ondansetron. After settling with her parents and having no further bouts of emesis she was sent home. She returned that afternoon febrile with increasing abdominal pain and emesis. Abdominal x-ray revealed a massively distended stomach and left diaphragmatic eventration. She underwent operative intervention and improved over the course of the following week. Conclusion Acute gastric volvulus presents a diagnostic challenge. In patients with vague abdominal complaints knowledge of the typical x-ray findings is essential in early identification and treatment.

A 12-year-old girl presented to the emergency room with severe abdominal pain, non-bilious emesis, and a 3-month history of progressively worsening lower abdominal pain, malaise, night sweats, and 4 kg weight loss. She had emigrated from Iraq 2 years earlier, and had been fed cow’s milk—often taken directly from the udder—after birth because her mother was unable to breastfeed. In the emergency room, her lower abdomen was tender, without peritonitis, and distended. Her white blood cell count, erythrocyte sedimentation rate, and C-reactive protein concentration were raised, whereas tests for hepatitis A, B, and C, HIV, and tuberculosis were negative. MRI of her abdomen and pelvis revealed extensive thickening of the bowel mesentery, peritoneum, and greater omentum, with a complex right-sided adnexal mass (appendix). We did an exploratory laparotomy to assess the mass, and encountered a dense, thick rind of tissue that was studded with tubercles and encased the peritoneal cavity (fi gure). A diagnosis of abdominal cocoon syndrome was made, and the abdomen was closed due to the extreme diffi culty in separating the fi brotic tissue from the abdominal wall. Frozen-section biopsy samples revealed caseating granulomas consistent with tuberculosis. A culture of the peritoneal fl uid grew Mycobacterium bovis subspecies bovis after 4 weeks and was resistant to pyrazinamide. The girl stayed in hospital for 3 months because she had recurrent episodes of partial or complete bowel obstruction that resolved with conservative, non-operative management. She was given isoniazid, rifampicin, and moxifl oxacin for 6 months while in hospital, followed by isoniazid and rifampicin for a further 12 months. On her last follow-up visit, she was no longer receiving antibiotic therapy, and was functioning normally. No further surgical intervention was planned for her, even though a repeat MRI of her abdomen and pelvis continued to show the thickened peritoneum and adnexal mass.
