RESUMEN
INTRODUCTION: Comorbidities such as chronic lung disease and gastroesophageal reflux (GERD), prematurity, and numerous other conditions may impact the success of LTR. Single-center studies are limited in terms of patient numbers and may be underpowered. OBJECTIVES: To analyze the impact of specific comorbidities on the operation-specific and overall surgical success of LTR in a large multicenter cohort and validate a predictive model for surgical success. METHODS: A large retrospective multicenter 10-year review was undertaken to validate the data of a previous single-center study (Wertz et al. Laryngoscope 2020) which identified specific predictive comorbidities which impacted LTR outcomes. A Monte Carlo simulation based on the previous data set suggested that 300-400 cases would be needed to optimize the statistical power of a Bayesian model developed from the single-center data to predict surgical success. An IRB-approved data-sharing agreement was executed for 4 large U.S. CENTERS: A virtual REDCap® data entry form inquired about patient characteristics that best predicted surgical success in the single-center model. These included demographics, surgical approaches, cardiac, airway, genetic, endocrine, musculoskeletal, gastrointestinal, and pulmonary comorbidities; details of the surgical procedures, and results of esophagogastroduodenoscopy (EGD), esophageal pH/impedance and flexible bronchoscopy with bronchioalveolar lavage (BAL) were included. Surgical success defined as successful decannulation or resolution of airway symptoms was recorded as single surgery success and overall success following open surgical revision surgery. Multivariate Bayesian analysis, logistical regression, and Kaplan-Meier analysis were performed. RESULTS: 542 patients were identified, including 165 from the single-center study and an additional 377 patients from the multicenter group. The median age was 36 months at the time of the most recent surgery. 70.9% of the LTRs were double-staged procedures. The overall success rate was 86.4% and operation-specific success rate was 69.2%. The specific comorbidities and aerodigestive test results that impacted success based on univariate analysis included staging, bronchiectasis, pulmonary hypertension, GERD, ASD, PDA, grade of stenosis, advanced levels of stenosis, Trisomy 21, MRSA, prior open surgery at another hospital, and gross appearance on EGD. Bayesian model averaging with backward selection was used to validate and refine a predictive model for surgical success with favorable receiver operating curve characteristics - AUC values of 0.827 for single surgery success and 0.797 for overall success. DISCUSSION: With over 500 patients reviewed, this was the largest multicenter study of LTR to date, which elucidated the impact of comorbidities on success with LTR and was able to improve upon the predictive modeling based on single-center data. Patient factors are most critical in the outcome of LTR. Stage and levels of stenosis, as well as pulmonary and GI conditions most strongly impact the likelihood of success. Future prospective case-control studies will be performed to further optimize the current model for outcome prediction and patient management.

OBJECTIVE: Pediatric tonsillectomy causes significant postoperative pain. Newer nonsteroidal anti-inflammatory drugs such as celecoxib control pain without increasing bleeding risk, but in prior studies provided only modest pain reduction at standard doses. We aimed to determine if high-dose celecoxib (double the usual pediatric dose) is effective for pain, without increasing bleeding or other risks. STUDY DESIGN: Randomized double-blind trial. SETTING: Pediatric tertiary center. METHODS: Children aged 3 to 11 years undergoing total tonsillectomy were randomized to receive celecoxib (6 mg/kg/dose) or placebo, twice daily, for up to 10 days. All cases were supplemented with acetaminophen and oxycodone as needed. All participants and personnel were blinded to treatment group. Subjects recorded coanalgesic consumption, pain, diet, and activity. RESULTS: The celecoxib group (n = 68) consumed 0.72 mg/kg of oxycodone, as compared with 1.12 mg/kg in the placebo group (n = 62), a 36% difference that was not significant. However, multivariate analysis by treatment group, separate from pain levels, confirmed that this reduction was due to celecoxib treatment (P = .03). In subjects with more prolonged pain (n = 88), celecoxib reduced consumption by 52% (P = .02). Celecoxib showed greater benefit for subjects in the prolonged pain group than for those in the lesser pain group (P = .006). Incidence of adverse events was similar between groups. Minor hemorrhage occurred in 4.6% (5 placebo, 3 celecoxib). CONCLUSION: High-dose celecoxib is effective in controlling pain after tonsillectomy, with no adverse effects in this relatively small sample. It reduces narcotic consumption, and its impact appears greater in children with higher degrees of pain. Celecoxib can be considered an effective alternative to ibuprofen after tonsillectomy. This trial was registered at ClinicalTrials.gov: NCT02934191.

OBJECTIVE: To determine parental satisfaction and cost-effectiveness of having a frenotomy performed in the office setting versus in the operating room under general anesthesia. METHOD: After obtaining IRB approval at The Children's Hospital of Philadelphia (CHOP), we performed a retrospective chart review of patients having a frenotomy in the office between 2003-2008. 55 patients met the criteria and 25 were consented and their parents interviewed. CONCLUSION: All participants reported an improvement in feeding within one day and up to two weeks following the procedure. Parents also reported being somewhat satisfied to very satisfied with having the frenotomy performed in the office versus under general anesthesia. There were no complications reported. Performing the frenotomy in the office provided patients with satisfaction as well as cost savings. The surgical fee for a frenotomy in the office is $850 and is the same as if the procedure is performed in the operating room. Performing a frenotomy under general anesthesia includes extra cost which consists of an anesthesia fee of $500-$900 and hospital charges ranging from $500-$8,000. Performing the frenotomy in the office on our 25 patients has resulted in a cost savings of more than $240,000 and the avoidance of general anesthesia in the first few weeks of life. Office frenotomy should be considered in children with ankyloglossia who present with difficulty nursing in the first week of life.
