The tension-free vaginal tape operation: Is the inexperienced surgeon a risk factor? Learning curve and Swedish quality reference

Abstract

Introduction: To reduce the risk of avoidable damage to the patient when training surgeons, one must predefine what standards to achieve, as well as supervise and monitor trainees' performance. The aim of this study is to establish a quality reference, to devise comprehensive tension-free vaginal tape (TVT) learning curves and to compare trainees' results to our quality reference. Material and methods: Using the Swedish National Quality Register for Gynecologic Surgery, we devised TVT learning curves for all Swedish TVT trainees from 2009 to 2017, covering their first 50 operations. These outcomes were compared with the results of Sweden's most experienced TVT surgeons for 14 quality variables. Results: In all, 163 trainees performed 2804 operations and 40 experienced surgeons performed 3482 operations. For our primary outcomes – perioperative bladder perforations and urinary continence after 1 year – as well as re-admission, re-operation and days to all daily living activities, there was no statistically significant difference between trainees and experienced surgeons at any time. For the first 10 trainee operations only, there were small differences in favor of the experienced surgeons: patient-reported minor complications after discharge (14% vs 18.4%, P =.002), 1-year patient-reported improvement (95.9% vs 91.8%, P
