French translation and validation of the OSATS tool for the assessment of surgical skill.

AIM OF THE STUDY: The OSATS rating scale is one of the tools most widely used in the scientific literature for assessing technical surgical skill. The aim of this study was to translate this scale into French (OSATS-FR) and validate it. METHODS: OSATS was translated into French by two independent translators. The two translations were pooled and back-translated by a third translator into English to produce a consensus version (OSATS-FR). Three independent assessors then used it to assess surgical skill in tracheostomy videos. The reproducibility of the scoring was measured. RESULTS: The OSATS-FR version was easily understood and used by all three assessors. In all, 18 procedures were assessed, performed by 14 interns and 4 senior surgeons. The mean OSATS-FR score was 18.6±4.08 for the interns and 31.6±1.62 for the seniors (p<0.0001). The Pearson correlation coefficient was 0.937 CI95% [0.867-1.269] between assessors 1 and 2, 0.977 CI95% [0.899-1.149] between assessors 1 and 3, and 0.965 CI95% [0.876-1.196] between assessors 2 and 3. Cronbach's alpha was greater than 0.9 for each assessor. CONCLUSION: OSATS-FR can distinguish between two groups with different surgical expertise and assess surgical skill with an inter-assessor reproducibility and internal consistency comparable to those of the English version.

Porcine model for tracheostomy training: evaluation of the content and construct validity.

PURPOSE: Tracheostomy is a key procedure that residents in Oto-Rhino-Laryngology, Head and Neck surgery must master as a fundamental component of their training. Swine is a potential model for tracheostomy training as it mimics human anatomy and provides realistic haptic feedback. The purpose of this study is to evaluate its content and construct validity in surgical tracheostomy training. METHODS: We carried out training sessions on dead swine with three groups of volunteers: young residents [postgraduate year (PGY)-1 to 3], experienced residents (PGY-4 to 6) and senior surgeons. Content validity was studied using questionnaires sent to senior surgeons. Construct validity was assessed by comparing the OSATS score on video analysis, between the three groups. RESULTS: 19 individuals participated in the training sessions. OSATS score were statistically different between groups (p < 0.05) with a mean score of 19 for young residents, 24.7 for experienced residents and 31.3 for senior surgeon, with a good inter-rater reliability (Pearson coefficient > 0.9). Experienced surgeons agreed that the model was a useful training tool, strongly agreed that it improved performance, and that it would be used to train their students. CONCLUSIONS: The dead pig is a suitable model to train for human tracheotomy, with good content and construction validity.

Transoral Laser Microsurgery versus Robot-Assisted Surgery for Squamous Cell Carcinoma of the Tongue Base (Oncological and Functional Results)-A Retrospective GETTEC Multicenter Study.

The base of the tongue (BOT) is the second most common site for squamous cell carcinoma (SCC) in the oropharynx. There are currently no clear guidelines for the management of BOT SCC. Our main objective was to compare the oncological outcomes of two minimally invasive approaches, transoral laser microsurgery (TLM) and transoral robot-assisted surgery (TORS). This was a retrospective French GETTEC (Groupe d'Études des Tumeurs de la Tête et du Cou) multicenter study of patients with BOT SCC removed surgically either by TLM or TORS between 2005 and 2021. The study group included 16 patients treated by TLM and 38 by TORS, with median follow-up times of 14.4 and 37.2 months, respectively. The overall survival (OS) rates at 2 and 3 years were 67% in the TLM group and 90% at 2 years and 86% at 3 years in the TORS group (p = 0.42, p = 0.20). There was no significant difference in recurrence-free survival (RFS) between the two techniques after 2 and 3 years. The tumors removed by TORS were significantly larger. Operative times were significantly shorter in the TLM group. There were no differences in feeding resumption; none of the patients in the TLM group required a tracheotomy. Postoperative hemorrhagic complication rates were similar in the two groups (12% for TLM and 13% for TORS). Both TORS and TLM showed encouraging oncological, functional, and safety results in BOT SCC even in recurrence or second primary cancer patients, without a technique being found superior in terms of OS or RFS. Tumors removed by TORS were larger without an increase in postoperative bleeding, extending the possibilities of transoral treatment.
