It's 4:00 AM and a patient comes in with a stab wound to the heart. Repair it by 4:02 and the patient will walk out in a few days. Wait until 4:05, and he'll be wheeled out in a bag. 🧵regarding a few surgical pointers on repair of traumatic cardiac injuries. (1/ )

And almost 3 decades later, in 2011, I prescribed immunotherapy for the very first time in my career and watched a patient’s melanoma melt away The gap between advances in basic science and progress in the clinic can be long but, without research, we won’t move forward at all!

@SeanLangenfeld @SurgEndosc @MSKCancerCenter @JohnRTMonsonMD @DrGarciaAguilar @R_Perez_MD @ASCRS_1 @Averywalker21 @escp_tweets @ianmpaquette @SWexner Agreed…what it also reminds us is endoscopy by far the most important part of surveillance and if it’s abnormal you should take it out.

Ryan Kalkbrenner continues to silent the “just tall” haters. Maybe it’s a skill to be 7’1 and move the way he does with his touch🤔 Kalk finishes with 17 pts, 7 rebs, 3 blocks. 8-9 from the field. 27-30 overall from the field through 5 games and still #1 in the NBA in FG%🔥
