@TheGastrologer @Samir_Grover @AmerGastroAssn 💯

With respect, this pricing isn’t justified. I’ve spent months tinkering with LLMs in the GI space - charging anything more than what a frontier LLM charges (Claude/ChatGPT) is unacceptable. These tools should democratize access to knowledge @Samir_Grover

@GI_Pearls But a salient point… it’s important for everyone (including GI folks) to look at nutritional contents, rather than merely assessing the degree of “ultra processed.”

@GI_Pearls Well, at least based on the article referenced, ultra processed foods are commonly associated with less fiber and more sugar. Hard to find consistently equivalent/matched nutritional contents in ultra processed foods. I feel some sensationalism/contrarianism in the article.

I wish more GI folks understood this. #GItwitter

Great weekend at @AmCollegeGastro Early Career Leadership Course ‘26! Honored to take part! Highly recommend introspective assessments like: ▪️ Ikigai ▪️Hogan assessment ▪️Goleman leadership styles Thank you @TrieuMD, @DrBloodandGuts, & @NeenaSAbrahamMD for an amazing course!

“MIRacle Sign” ➡️ inducible reversible blanching on EGD with CO2 insufflation. Clue to diagnose borderline or overt gut ischemia

Lately, I keep hearing that IFX is the only drug with clinical trial in perianal Crohn’s...🧐 So, I’ve updated my cheat sheet on medical therapy trials in perianal CD, summarizing 15 RCTs into just one page. Hope it’s useful! Surgical part coming soon (If any is missing please let me know and I will add it) ⏳➡️ibd-eii.com/cheat-sheet/

The 'pits' on the polyp are base or openings of the crypts. This paper (bookmark!) details the 3D dimension of the crypts: link.springer.com/article/10.100… As the cells proliferate, the gland architecture distorts, so does the pit pattern. Used in Kudo, JNET, NICE classification

AI is not gonna replace physicians. However, physicians who don’t utilize AI will be replaced. When I am sick I want AI going through all my data and then render an opinion and an excellent clinician doing the same. Then the two of them can work together to fix me.

#CGH4ALL @AGA_CGH 📣 Exciting data in #EoE: A potential step toward restoring dietary freedom while maintaining disease control in EoE. 🔹Open-label pilot study, patients (6–25 yrs) w/ milk/egg/soy/wheat-triggered EoE 🔹Dupilumab for 3 months, followed by stepwise food reintroduction up to 12 months 🔹All completers successfully reintroduced ≥1 trigger food, and many expanded diets every 3 months #GITwitter #MedTwitter 🔗cghjournal.org/article/S1542-… Reported by @AasthaBharwad @EdoardoSavarino, @NdeBortoli, @SebastianZeki, @stevenbollipo, @DrCJudge, @my_ueg, @virgisolitano, @eathar_s, @DaniyalAbbasMD

First double-blind, placebo-controlled RCT in @TheLancet showing that SEMAGLUTIDE reduces ALCOHOL intake in people with BMI >25. Potentially practice-changing. shorturl.at/B45aU

@yuvalpatelMD 💯💯

Saw patient who had hemorrhoid surgery for rectal 🩸, bleeding persisted, came to my clinic, did colonoscopy and has colon cancer All 🩸 is not hemorrhoids We live in an era of worsening colorectal cancer rates, get a colonoscopy if rectal🩸 #medtwitter #gitwitter

AI in GI training key points ▪️Set competencies & policies ▪️Delay use in endoscopy ▪️Taper autonomy & turn AI off at times ▪️Clinic scribes help; verify output ▪️LLMs are not stand alone ▪️Use evidence tools & cross-check ▪️AI is adjunct not decision maker Keep convo going!

ACG Governors and the Early Career Leadership Program are here for #ACGAdvocacyDay in DC, advocating for GI physicians and patients on key issues like preventive service coverage and prior authorization challenges! Follow along as we check in with them throughout the day. 🧵

💬 Viewpoint: Mandatory annual training modules consume millions of physician‑hours each year, yet their largely passive formats may offer limited educational value while contributing to administrative burden and clinician burnout. ja.ma/4vvyvBm

Traded the endoscopy suite for Capitol Hill today. @AmCollegeGastro Advocacy Day is a reminder that the best outcomes start long before the colonoscopy - sometimes in a congressional office. 🏛️ #GITwitter

Great fun writing this article on landmark papers in decomp cirrhosis and CSPH. Thanks @ReibergerThomas and Prof Tsochatzis for being co-authors and @FrontGastro_BMJ for publishing! Check out 👇 doi.org/10.1136/flgast… @EASLedu @BASLedu @BSGTrainees @AASLDtweets #livertwitter

Love this paper 1. Checking ANA in everyone with elevated ALT is unhelpful, sometimes harmful, usually confusing 2. Biopsy when ALT <100 but ANA elevated is not useful 3. Autoimmune hepatitis is a clinical diagnosis and frequently made DESPITE biopsy findings

@GI_Guy @drkeithsiau You think one directed clip is enough?

What would you if you found this polyp on colonoscopy?
