Improving tonsillectomy outcomes: a five-year experience of practice evolution at a tertiary paediatric centre
Insights
Intracapsular Coblation tonsillectomy (ICT) significantly reduced bleeding complications in children undergoing tonsillectomy for sleep-disordered breathing (SDB). This technique became standard practice, improving patient safety and reducing readmissions.
Area of Science:
- Otolaryngology
- Pediatric Surgery
- Surgical Outcomes Research
Background:
- Tonsillectomy techniques have evolved, necessitating practice updates based on clinical evidence.
- A tertiary pediatric center analyzed tonsillectomy data over five years to assess technique efficacy.
Purpose of the Study:
- To evaluate the impact of changing tonsillectomy techniques on postoperative hemorrhage and readmission rates.
- To determine the preferred surgical method for tonsillectomy in children with sleep-disordered breathing (SDB).
Main Methods:
- Retrospective analysis of electronic health records for 2,583 pediatric tonsillectomies performed between 2017 and 2022.
- Comparison of postoperative hemorrhage and readmission rates across different tonsillectomy techniques: extracapsular bipolar dissection, extracapsular Coblation tonsillectomy (ECT), and intracapsular Coblation tonsillectomy (ICT).
Main Results:
- Intracapsular Coblation tonsillectomy (ICT) demonstrated the lowest bleed rate (1.9%) compared to bipolar dissection (7.1%) and extracapsular Coblation tonsillectomy (ECT) (9.7%).
- Following a shift towards ICT, overall readmission rates for hemorrhage decreased from 9.1% in 2017 to 5.2% in 2022.
- Registrar proficiency and performance of ICT increased significantly, indicating successful adoption of the technique.
Conclusions:
- Intracapsular Coblation tonsillectomy (ICT) is the preferred technique for tonsillectomy in pediatric patients with SDB due to superior safety and reduced hemorrhage.
- Evidence-based evaluation of surgical techniques is crucial for minimizing complications and enhancing patient safety in pediatric tonsillectomy.
- Continuous outcome assessment drives the evolution of surgical practices, leading to improved patient outcomes.
Introduction:
Tonsillectomy techniques have evolved significantly. Here, we show how our practice changed based on evidence from nearly 2,600 tonsillectomies over five years at a tertiary paediatric centre.
Methods:
This is a case series with retrospective analysis of data from electronic records for children undergoing tonsillectomies between 2017 and 2022 at a tertiary paediatric centre.
Results:
A total of 2,583 tonsillectomies were analysed. The main indication was sleep-disordered breathing (SDB) (82%). In the 2017 audit phase, secondary and primary bleed rates were 6.2% and 0.5%, respectively. Readmission rates for post-tonsillectomy haemorrhage in 2017 were 6% for extracapsular bipolar dissection, 9.8% for extracapsular Coblation tonsillectomy (ECT), and 0% for intracapsular Coblation tonsillectomy (ICT). This led to an increase in ICT use from 22% in 2017 to 74% in 2022, while bipolar dissection and ECT declined to 6% and 12%, respectively. The readmission rate dropped from 9.1% (2017) to 5.2% (2022), and overall bleed rates fell from 6.2% to 4.4%. Bleed rates varied by technique: ICT 1.9%, bipolar dissection 7.1%, ECT 9.7%. Seven patients required revision surgery (<1%); surgeon's grade did not significantly impact outcomes. Registrars increasingly performed tonsillectomies using ICT (27.4% in 2017 to 76.5% in 2022).
Conclusions:
ICT is our standard technique for SDB due to its lower rates of postoperative haemorrhage and return to theatre. Given the higher haemorrhage rates with ECT, extracapsular dissection is preferred when needed. Registrars are trained in ICT. This shift, based on evidence of lower morbidity, shows how outcome evaluation and technique evolution can minimise complications, enhancing safety for the children we treat.
