So Pradeep, then what was ... what were the findings of our study?

So our study included one zero nine, uh, duodenal resections in one zero one patients, which represent substantially real-world experience in this challenging area.

Despite the technical difficulty, we could achieve technical success of more than ninety-eight percent in our cases, with R0 resection rates above ninety percent.

Importantly, delayed adverse events were very low, less than three percent, and none of the patients required surgery.

One of the most important finding was, uh, that severe submucosal fibrosis is a strong predictor of procedural adverse events.

We also observed that ulcerated lesions were strongly associated with severe fibrosis, which is a clinically important because in ...

it helps in identifying this, an-anticipate difficult dissection, uh, before, even before the start of procedure.

And as you know, duodenal wall is thin and, uh, after ESD or EFTR, what closure study, strategy was adopted, uh, as you said, the adverse event even for less than three percent? So what was this closure strategy?
