Abstract Introduction: Few studies have assessed the impact of obesity on laparoscopic cholecystectomy (LC) in pediatric patients. Materials and Methods: Children who underwent LC were identified from the 2012 to 2013 American College of Surgeons' National Surgical Quality Improvement Program Pediatrics data. Patient characteristics, operative details, and outcomes were compared. Multivariable logistic regression was utilized to identify predictors of increased operative time (OT) and duration of anesthesia (DOAn). Results: In total, 1757 patients were identified. Due to low rates of obesity in children <9 years old, analyses were limited to those 9–17 ( n = 1611, 43% obese). Among obese children, 80.6% were girls. A higher proportion of obese patients had diabetes (3.0% versus 1.0%, P < .01) and contaminated or dirty/infected wounds (15.1% versus 9.4%, P < .01). Complication rates were low. The most frequent indications for surgery were cholelithiasis/biliary colic (34.3%), chronic cholecystitis (26.9%), and biliary dyskinesia (18.2%). On multivariable analysis, obesity was an independent predictor of OT >90 (odds ratio [OR] 2.02; 95% confidence interval [95% CI] 1.55–2.63), and DOAn >140 minutes (OR 1.86; 95% CI 1.42–2.43). Conclusions: Obesity is an independent risk factor for increased OT in children undergoing LC. Pediatric surgeons and anesthesiologists should be prepared for the technical and physiological challenges that obesity may pose in this patient population.

BACKGROUND:Youth ice hockey is an exciting sport with growing participation in the United States. Updated assessment of injury patterns is needed to determine risk factors for severe injury and develop preventive efforts. The purpose of this study was to evaluate our experience as a level 1 pediatric trauma center in Minnesota treating injured youth ice hockey players.METHODS:Children ≤18 years old who presented to our institution from July 1997 to July 2013 with an injury sustained while participating in ice hockey were identified. Patient demographic information, injury characteristics, and outcomes including use of computed tomography, hospital admission, and procedures were obtained. Age- and gender-specific patterns were determined for injuries and outcomes.RESULTS:Over 16 years, 168 injuries in 155 children occurred, including 26 (15.5%) injuries in girls. Extremity injuries were most common, followed by traumatic brain injury. Injuries to the spine, face, and trunk were less common. Traumatic brain injury and injuries to the spine were most common in younger children (≤14 years old) and girls, whereas injuries to the face were most common in older players (≥15 years old). Most injuries resulted from intentional contact. Admission to the hospital was needed in 65 patients, including 14 (8.3%) who needed intensive care. A major procedure was needed by 23.2% of patients because of their injuries.CONCLUSIONS:Youth ice hockey trauma can be severe, necessitating a thorough evaluation of injured children. Injury patterns are influenced by age and gender, providing an opportunity for targeted preventive efforts.

Objectives To review the need for operative intervention and critical care services for motocross truncal injuries in children. Design cohort Retrospective review of patients identified via the hospital trauma registry. Setting Our Level 1 Pediatric Trauma Center serves five motocross tracks. These patients require frequent medical care for injuries. Participants All patients ≤17 years of age with truncal injuries sustained during motocross activities, between 2000 and 2011, were identified through the trauma registry. Primary and secondary outcome measures Operative intervention, intensive care unit (ICU) admission, length of stay, morbidity and demographics were reviewed. Results Motocross injured 162 children. Thirty (18.5%) were thoracic or abdominal injuries. Operative intervention was required in eight (27%) patients. Mean injury severity score (ISS) was 11.8. ICU admission was required in 50% and average hospital length of stay was 4.1 days. The most common injuries include pulmonary contusion, pneumothorax, spleen and liver lacerations. 13% of subjects suffered truncal injury from motocross on more than one occasion. Conclusions Paediatric motocross-related truncal injuries are significant. Surgical intervention is required in 27% of patients. The lower ISS incurred from motocross combined with high surgical and ICU admission rates suggests focal high-impact injuries to the chest and abdomen. Despite significant injury, 13% of motocross patients suffer recurrent injuries. Parents and children need injury prevention education.

Objective. Primary hyperparathyroidism (HPT) is unusual in children. We reviewed our experience with HPT to better characterize these children. Methods. The retrospective review of patients &lt;19 years old who underwent parathyroid resection for primary HPT from 1970 to 2000 was performed at a single institution.. Results. Fifty-two patients were identified. Median age was 16.8 years (range: 4–18.9) with a female-to-male ratio of 3:2. Eighty-five percent had an elevated parathyroid hormone (PTH) level, and 15% had an inappropriately normal PTH level during hypercalcemia. Serum calcium was elevated in all patients except for 2 with multiple endocrine neoplasma (MEN)-IIA and 1 with familial non-MEN HPT, but both had elevated PTH levels. Alkaline phosphatase levels were significantly higher in children with documented bone involvement. At presentation 41 patients (79%) were symptomatic and end-organ damage (nephrocalcinosis, nephrolithiasis, acute pancreatitis, or bone involvement) occurred in 23 patients (44%). Thirty-four patients (65%) had a single adenoma; hyperplasia was identified in 16 patients (27%), and of these cases, 57% occurred in patients diagnosed with MEN-I. Short-term complications included transient hypocalcemia in 29 patients (56%) and transient vocal cord paralysis in 2 patients (4%). Long-term complications were significant for permanent hypocalcemia in 2 patients (4%) and no recurrent laryngeal nerve injuries. No parathyroid abnormalities were identified during exploration in 4 (8%) children. Long-term follow-up was achieved in 98% of patients for a mean and median of 13 years. Resolution of hypercalcemia was achieved in 94% of cases. Conclusion. The diagnosis of primary HPT in pediatric patients is frequently delayed, is commonly symptomatic, and has significant morbidity. For children in whom HPT is suspected, evaluation of serum calcium and PTH levels is diagnostic in 100% of children. Parathyroid resection is effective at restoring normal serum calcium, has few complications, and is the treatment of choice for children with primary hyperparathyroidism.
