Surgical repair of massive hemorrhage secondary to button battery ingestion causing aortoesophageal fistula.

BACKGROUND: In pediatrics, foreign body ingestion poses unique challenges. Each case is unique given variability in timing, type, and size of object, compounded by underlying comorbidities and age. In the mid-1990s, mortality and morbidity associated with button battery (BB) ingestion (BBI) emerged corresponding to modification in battery fabrication towards higher voltage, large-diameter lithium cells. AIMS: To describe the case and management of a BBI in a pediatric patient necessitating the use of cardiopulmonary bypass and deep hypothermic circulatory arrest (DHCA). MATERIALS AND METHODS: A 17-month-old female presented with the sudden loss of consciousness at home. Chest X-ray revealed an esophageal foreign body suspicious for BBI. A massive upper gastrointestinal bleeding was temporized with packing. The patient was urgently taken to the operating room for sternotomy, establishment of cardiopulmonary bypass (CPB) with deep hypothermic circulatory arrest (DHCA), removal of BB, repair of the left common carotid artery, esophageal, and tracheal injuries. DISCUSSION: Successful management of BBI requires coordinated care and a multidisciplinary approach. A high degree of clinical suspicion for BBI is imperative to facilitate early aggressive interventions. Lateral and anteroposterior chest films should be obtained in any suspected BBI. CONCLUSION: This case demonstrates the utility of CPB and DHCA where control of bleeding secondary to BBI is not otherwise possible.

Impact of early surgical correction or palliation of congenital heart defects in infants with symptomatic viral respiratory tract infections in the current era.

Objective: This study investigates the influence of timing of surgery among infants with congenital heart disease and active respiratory tract infections in a contemporary Western Canadian cohort. Methods: This was a retrospective matched cohort study of infants aged 1 week to 6 months undergoing surgical repair of congenital heart disease between 2014 and 2017. Case patients had active respiratory tract infections preoperatively and were matched to control patients based on primary heart lesion. The primary outcome was time to extubation. Results: We identified 20 cases (median age, 3.4 months [range, 2.4-4.3 months]) that were matched to 40 controls (1:2 ratio). In case patients, surgery occurred at a median of 1 day after the positive viral testing. There were no statistically significant differences between cases and controls in time to extubation (59 vs 34 hours [P = .12]), postoperative vasoactive scores at 24 hours (0 vs 0 [P = .53]), 48 hours (0 vs 0 [P = .23]), maximum vasoactive score in postoperative period (5 vs 5.5 [P = .54]), or time to hospital discharge (13 vs 12 days [P = .39]). Case patients had increased duration of total respiratory support (including noninvasive ventilation, 3.5 vs 2 days [P = .02]) and postoperative intensive care unit length of stay (5.5 vs 3 days [P = .01]). Conclusions: Cardiac surgery on infants with congenital heart disease during an acute viral respiratory tract infection may yield a clinically relevant prolongation in time to extubation.

Chylothorax and pleural effusion in contemporary extracardiac fenestrated fontan completion.

BACKGROUND: We hypothesized that chylothorax could be a sign of intolerance to the Fontan physiology, and thus patients who develop chylothorax or pleural effusion have worse medium-term to long-term survival. METHODS: A total of 324 patients who underwent the Fontan operation between 2000 and 2013 were included. Chylothorax was defined as ≥5 mL/kg/day of chylomicron-positive chest drainage fluid no earlier than postoperative day 5 or drainage with >80% lymphocytes. Outcomes were compared between the chylothorax and non-chylothorax groups by the Kaplan-Meier method and log-rank test. Independent predictors of chylothorax and number of days of any chest drainage were analyzed with multivariable logistic regression and multivariable generalized negative binomial regression for count data, respectively. RESULTS: Chylothorax occurred in 78 patients (24%). Compared with the non-chylothorax group, the chylothorax group had a longer duration of chest tube requirement (median, 18 days vs 9 days; P < .000) and a longer length of hospital stay (median, 19 days vs 10 days; P < .000). Eight patients (10.3%) required thoracic duct ligation. The chylothorax group had lower freedom from death (P = .013) and from composite adverse events (P = .021). No predictor was found for chylothorax. Pulmonary atresia (P = .031) and pre-Fontan pulmonary artery pressure (P = .01) were predictive of prolonged pleural effusion (>14 days). CONCLUSIONS: Occurrence of chylothorax following the Fontan operation can be a marker of poorer medium-term clinical outcomes. It is difficult to predict occurrence of chylothorax owing to its multifactorial nature and involvement of lymphatic compensatory capacity that is unmasked only after the Fontan operation.
