Study limitations
The limitation of this study is that it was a single-center study with a series of TEF cases; therefore, future research from multiple centers with a larger number of cases is mandatory to accurately assess the effectiveness of this technique. In addition, the follow-up period in this study was brief, and a long-term follow-up period is required. The study had no specific or innovative trials, making the methodology, interventions, and results easily generalizable and applicable.
