Introduction: The BiZact device is one of the latest hot tonsillectomy devices.1 Hot techniques have shown to result in quicker operating times and decreased intra-operative bleeding however concern remains around post operative complication rates particularly post tonsillectomy haemorrhage (PTH).2 This study hypothesizes that BiZact PTH rates will be similar to other hot tonsillectomy techniques
Aim: To look at complication rates, namely bleeding, infection, readmission and return to theatre following the use of the BiZact device
Method: Retrospective cohort study looking at all tonsillectomies performed by a single surgeon using BiZact over a 15-month period. Systematic review of clinical, operation and admission notes provided information regarding surgical indication, confirmation of BiZact tonsillectomy, complications and subsequent treatment including return to theatre.
Results: 99 patients underwent tonsillectomy with an overall PTH rate of 6%, all being Grade B1 bleeds. There were no primary bleeds, cases requiring blood transfusion, treatment under anesthesia or return to theatre. There was a 36% increase in rate of PTH for those who had tonsillectomy for recurrent tonsillitis compared to sleep disordered breathing.
Conclusions: This study found similar PTH rates to previously published data on the BiZact device and to other hot techniques.1,2 The return to theatre rate for PTH with BiZact was much lower than previously reported for all other techniques.2 The BiZact device is marketed with quicker operative times. It would be interesting to evaluate theatre time and overall cost of comparative operations in future.
