🎯 A milestone one in @Nature 🎯
🦠 Responders with vaccine induced t-cells have prolonged RFS compared to non responders
💉 Vaccine for PDAC not a dream anymore?!

Pip/Tazo is in the @WHO Watch category of the AWaRe classification and it should not be used deliberately! It’s a lazy way of treating SSI. More appropriate to tailor the treatment based on bile stenting, preop bile culture, and rectal swab colonization with MDR! @heatherevansmd

Antibiotics 💊 for prophylaxis during pancreatoduodenectomy 🙋🏻♀️ … did you change your practice?

We express our sincere gratitude
for your attention and interest in our recently published study @BjsOpen titled "Piperacillin/tazobactam for surgical prophylaxis during pancreatoduodenectomy: a meta-analysis ." We are hopeful that the findings from this study will contribute towards enhancing the outcomes of the whipple procedure. @hollylneville @mhshospital

Piperacillin/tazobactam for surgical prophylaxis during pancreatoduodenectomy: meta-analysis
➡️doi.org/10.1093/bjsopen/zrae…
Piperacillin/tazobactam as antimicrobial prophylaxis significantly lowers the risk of postoperative surgical-site infections, major surgical complications (complications classified as Clavien–Dindo grade greater than or equal to III), clinically relevant postoperative pancreatic fistulas (grades B and C), and mortality, hence supporting the implementation of piperacillin/tazobactam for surgical prophylaxis in current practice.

🚨PANDORINA, a binational 🇳🇱🇮🇹RCT of drain 🆚 no drain in distal pancreatectomy out in @LancetGastroHep !
✅Major morbidity 20% vs 15%
✅POPF 27% vs 12%
➡️A no-drain policy is safe and reduced POPF and should be the new standard approach

1⃣ January 2023: Pancreatic cysts when to stop surveillance !? 👇👇👇
Pancreatic cysts 🧐 When to Stop Surveillance ?!
🔥 A burning issue on @AmJGastro
🛑 STOP of follow-up depends on interval stability and size either after 5 or 10 years
Oversurveillance discouraged 🤜🤛 More evidence needed !!!
Your practice ?! 😱
