- "During full-thickness transanal dissection, if you see fat around the rectum, you can get closer to the rectum because that means you are not in the real rectal wall." — Alberto Peña (clinical) [Ep 2 · 27:04](https://library.globalcastmd.com/watch/surgical-procedures-for-hirschsprung-disease-736?t=1624)
- "If you stay right on the bowel wall during dissection, you will not provoke denervation of the urinary tract, as Dr. Swenson emphasized." — Alberto Peña (host_summary) [Ep 2 · 27:23](https://library.globalcastmd.com/watch/surgical-procedures-for-hirschsprung-disease-736?t=1643)
