The spontaneous passage of esophageal coins in children.

OBJECTIVES: To determine the likelihood of spontaneous passage of esophageal coins to the stomach in children and to determine the effect of initial coin location on spontaneous passage. DESIGN: Retrospective review of medical records and radiographs. SUBJECTS: Consecutive patients 18 years or younger presenting during a 24-month period (October 1995 to September 1997) whose evaluation revealed an esophageal coin. SETTING: The emergency department of a large, urban academic children's hospital. MAIN OUTCOME MEASURES: Independent measures were time between ingestion and radiographs, initial location of the coin, and categorization of case as "simple" (patients without a history of esophageal disease or surgery, with a single esophageal coin lodged less than 24 hours, and with no respiratory compromise on presentation) or "complex." Dependent measures were spontaneous passage of the coin to the stomach and the time to passage. RESULTS: A total of 116 cases were included in the analysis, of which 84 were simple and 32 complex. Among the 84 simple cases, the coin was initially located in the proximal third of the esophagus in 54 (64%), the middle third in 7 (8%), and the distal third in 22 (26%). For the 32 complex cases, the initial location of the coin was the proximal third of the esophagus in 27 (84%) and the middle third in 5 (16%). Subsequent radiographs were obtained in the emergency department in 58 (69%) of the simple cases. Among these cases, spontaneous passage of the coin to the stomach occurred in 16 (28% [95% confidence interval, 21%-41%]). By initial coin location, spontaneous passage in this group occurred in 22% (7/32) of proximal, 33% (2/6) of middle, and 37% (7/19) of distal esophageal coins (P >.05). Subsequent radiographs were obtained in 14 (44%) of the complex cases; no coin had passed spontaneously to the stomach in these patients (0% [95% confidence interval, 0%-20%]). CONCLUSIONS: Children with a single esophageal coin seen within 24 hours of ingestion, who have no history of esophageal disease and no respiratory compromise on presentation, have a 28% chance of spontaneous passage of the coin to the stomach. Coins in the upper as well as the lower esophagus pass spontaneously. Observing these children for 12 to 24 hours prior to invasive procedures will reduce complications and costs.

Four strategies for the management of esophageal coins in children.

OBJECTIVE: To compare clinical outcomes and costs under 4 strategies for the management of esophageal coins in children. METHODS: We developed a decision analysis model of 4 possible strategies for managing esophageal coins: 1) endoscopic removal under general anesthesia; 2) esophageal bougienage, 3) an outpatient 12- to 24-hour observation period to allow spontaneous coin passage; and 4) an inpatient observation period. Probabilities of success and complication rates for endoscopy and esophageal bougienage were obtained from published data. The probability of spontaneous coin passage was derived from chart review data at our institution. Costs were calculated from charges using a cost-to-charge ratio of.72. Hypothetical patients included in the model were those with a single esophageal coin presenting within 24 hours of ingestion, with no respiratory compromise on presentation and with no previous history of esophageal disease. Strategy-specific outcomes were overall complication rate and total cost in dollars per patient. Sensitivity analyses were performed to account for variations in the data. RESULTS: The esophageal bougienage strategy resulted in no complications and a total cost per patient of $382, which represents a marginal advantage of $2915 per patient compared with the endoscopic removal strategy. On sensitivity analysis over the range of success and complication rates of bougienage, this strategy maintained a considerable decrease in both overall complications and total cost per patient compared with all other strategies. Both outpatient and inpatient observation strategies had overall complication rates of 4.2% compared with the complication rate of 5.8% for the endoscopy strategy. The total cost per patient under these strategies was $2439 for the outpatient and $3141 for the inpatient strategy, representing a marginal advantage of $858 and $156 per patient, respectively, compared with the endoscopy strategy. Both observation strategies maintained a lower overall complication rate compared with endoscopy in the sensitivity analysis. The outpatient observation strategy maintained a marginal advantage of $645 to $1257 per patient compared with endoscopy; however, the inpatient observation strategy total cost per patient surpassed that of endoscopy at a spontaneous passage rate <23%. CONCLUSIONS: Given the high success and low complication rates reported for esophageal bougienage, substantial savings in overall complications and costs would be expected with the use of this procedure. With spontaneous passage rates >23%, either an outpatient or an inpatient observation strategy would reduce costs and complications, compared with endoscopic removal of all esophageal coins.

Impact of sonography on the diagnosis and treatment of acute lower abdominal pain in children and young adults.

OBJECTIVE: Our purpose was to evaluate the impact of sonographic data on clinical physicians' diagnostic confidence and their treatment of children and young adults with acute lower abdominal pain. SUBJECTS AND METHODS: Senior surgical and emergency department staff completed questionnaires before and after abdominal sonography was performed on 94 of 101 consecutive children and young adults with acute lower abdominal pain, pelvic pain, or both. Physicians who were unaware of sonographic data stated the most likely diagnosis and their level of confidence in their diagnosis and then formulated clinical plans. After they were given sonographic data, physicians again stated the most likely diagnosis, estimated their level of confidence, and formulated revised treatment plans. RESULTS: Sonographic data resulted in revised clinical diagnoses in 52% of the patients. Overall, the gain in diagnostic confidence for the entire study population was 33% (95% confidence interval [CI], 27-38%; p < .0001). The impact on the physicians' confidence was greater in those children and young adults whose diagnoses changed after sonography (mean increase in physicians' confidence, 48.3%; 95% CI, 47-75%). In patients whose diagnoses were not changed after sonography, the mean increase in physicians' confidence was 17.6% (95% CI, 11-24%; p < .0001 [analysis of variance]). Physicians used sonographic data to change initial treatment plans in 43 patients (46%). Of these 43 patients, a lower intensity of care was given to 30 patients (70%) and a higher intensity to 13 patients (30%). CONCLUSION: Sonographic data frequently changed initial clinical diagnoses, thus increasing diagnostic confidence and changing clinical treatment decisions in the setting of acute lower abdominal pain in children and young adults.
