We suggest imaging according to this algorithm; but love to have the discussion! We firmly believe imaging is underutilized in fistula surgery! https://t.co/tnYhnwPsdi

ESCP guidelines emphasize loose setons as a safe, sphincter-preserving option for complex anal fistula. But does technique matter for patients.

In our randomized controlled trial, we compared three different seton knot techniques in high transsphincteric anal fistulas.

Key finding: QoL significantly improved over time in all groups, with no difference between knot types.

Feeling so lucky with my course directors! Big thanks to David and Nunoo for letting me practice on the Medtronic HUGO robot—also huge shout-out to @ISUCRS for making it happen!

@ciirarref So can you explain in what way she, or the situation, will improve after airing this in social media? In what way will this help you or her? I think it is embarrassing and unprofessional for you and your service to out her in this way.

We are starting the planning of our new OR dpt. What innovations or design features do we have to look into to optimise our minimally invasive surgery suites? @escp_tweets @ASCRStweets @DSCRS_NL #colorectalsurgery @SWexner

@TechColoproctol have you fixed the flaw yet so that Letters to the editor can be published free of charge?

@drkeithsiau @TedEdson1 Recto-anal inhibition reflex!

@dickandtinasson @OGdukeneurosurg That is not general surgery ; it is a highly specialized procedure for colorectal surgeons!

@deanlute @escp_tweets @DCRjournal Hi Dean! The size of the internal opening does not influence the technique or outcome of Flap repair; so indeed I would suggest a core-out and bulky flap. I see no use for stoma’s; a benefit has never been shown.

Nature publishes an article titled “How can I publish open access when I can’t afford the fees?”

Also Nature: Pay to read it 🤯

How well does Goodsall’s Rule hold up to modern imaging?

We revisited this surgical classic with MRI in 305 fistula cases. The result: ~49% accuracy overall. Anterior fistulas predict better; posterior less so. MRI is essential.

Excellent retrospective analysis from our Pelvic Radiology team. Thanks to our rising star @digdemkuruoz for the huge effort.
