Safety of outpatient admission and comparison of different surgical techniques in adult tonsillectomy.

Abstract

To investigate the safety of outpatient admission and the effects of surgical technique in tonsillectomy operations of adult patients. The digital database was scanned for patients aged ≥ 15years that underwent tonsillectomy in our institution between years 2014 and 2018. Demographic and clinical characteristics, the surgical technique, length of stay (LOS) in hospital, re-admissions after discharge, complications and interventions performed were recorded. A total of 276 patients met the inclusion criteria, comprising 139 (50.4%) females and 137 (49.6%) males with a mean age of 27.17 ± 9.41years. The most common indication was recurrent tonsillitis (n = 223, 80.8%), and surgical techniques used were bipolar scissors (CURIS®, Sutter Medizintechnik, Germany) (n = 137, 49.6%), cold dissection (n = 75, 27.2%) and/or plasma blade (PEAK Surgical, Medtronic, USA) (n = 64, 23.2%). A total of 43 (15.5%) re-admissions from 37 (13.4%) patients were recorded because of bleeding (n = 33, 70.2%) and/or odynodysphagia (n = 13, 27.7%). Non-surgical interventions were sufficient in 32 (74.4%) cases, while surgical interventions were required in 11 (25.6%) patients. In patients where "hot" techniques (bipolar scissors, plasma blade) were used and in patients with complaints in the first 24h postoperatively, significantly increased rates of elongated LOS values for more than 1day were determined (p < 0.01, p < 0.001). Adult tonsillectomy is a safe surgical procedure with low complication, re-operation and mortality rates. Significantly increased rates of elongated LOS values for more than 1day and re-admissions after discharge were determined in those patients having complications in the first 24h postoperatively. Cold dissection seems to be more advisable than hot techniques for outpatient tonsillectomy among adult patients.
