I found myself with free time and a growing frustration over questionable "melena" referrals. The end result -- I created an app dubbed "ShatGPT." Link below🔗

@ebtapper @AmCollegeGastro Great doc indeed!

Retatrutide phase 3 obesity trial just came out and the results are genuinely insane:

- 28.3% bodyweight lost on 12mg over 80 weeks
- 70.3 pounds on avg. or 31.9 kg
- 45.3% of patients hit 30%+ weight loss (this is bariatric surgery territory)
- 30.3% weight loss (85 lbs) at 104 weeks in higher-BMI patients
- 65.3% of 12mg patients dropped below the obesity BMI threshold
- 19% loss on 4mg over 80 weeks (47.2 lbs) with fewer dropouts than placebo (4.1% vs 4.9%)
- significant drops in blood pressure, triglycerides, non-HDL cholesterol, waist circumference, and hsCRP
- no cardiac or liver signals

Retatrutide is going to completely overshadow tirzepatide and semaglutide, and take the throne as the best-selling drug of all time.

The OCULUS trial settles the longstanding debate: whether to continue to hold GLP-1/GIP agonists like Mounjaro before upper endoscopy. These were the results👇

Proof of concept.
Made an app that searches🔎 for guideline updates on a topic, summarize those updates🗒️, and converts the summary to an audio file📻 that can be played at 1.5 x speed. 🤯

@v_computer @RevenueCat How would you recommend completing the screenshot portion of the app store submission for both the iphone/ipad. Would this be completed within vibecodeapp or would you recommend other sources.

@AkshataMoghe It has been too long. I have added two more kids to my army since we last saw one another :)

Billroth II Gastrojejunostomy – Endoscopic Landmarks

AFFERENT LIMB LOCKED IN <3 SEC
• Almost always on the RIGHT
• Bile lake + bubbles = 100 % afferent (panel a)
• Entrance frequently kinked/twisted (panel c)

CLASSIC DUAL-LUMEN VIEW
• Panel b → efferent left, afferent right

Pro trick: No bile visible? Flush 100 ml water → bubbles float straight into afferent limb (works even on PPI)

Your fastest afferent limb trick?

Not sure what to do in cases of:

Early year PSAs #2 for #GI fellows:

🟢Use professional language to talk about colorectal surgeries (👇)

🟢🔑 differences = rectum gone (bottom 3) = ostomy.

🟢 Location of #IBD dictates surgical approach, understand this, and CRS will like you.

[Yuri Gorelik @GorelikYuri]

In isolated distal esophageal #EoE is more like GERD as can be assumed from this @AGA_CGH study.
Patients with isolated distal esophageal eosinohils were much more likely to respond to PPIs

[Weston Bettner @westonbettner]

@DouglasAdlerMD Agree with your approach. I tend to dilate and then biopsy to break up further.

10 years ago I thought this was settled. I guess it’s still happening? #gitwitter

Happy #ColorectalCancerAwarenessMonth, #AGAGastroSquad!

This month and all year long, we encourage CRC screening starting at age 45. If your ID says 1980, it's your year to #GetScreened! Do your part – it takes all of us to achieve a world free of #CRC. 💙

Special thanks to @AmerGastroAssn and podcast host @MJWhitsonMD for this unique opportunity to guest host.

Struggling with #EoE?🧐 You're not alone. Tune into 🎙️ Small Talk, Big Topics this week for expert guidance on managing the disease. We are joined by EoE powerhouses💪 - Dr. Kristle Lynch (@KristleLynchMD) and Dr. Evan Dellon.

[Weston Bettner @westonbettner]

@AmerGastroAssn The episode also alludes to the importance of bringing pastries and coffee to pathologists if you want to review slides with them. 😉

@DrKSchmiddie @AmerGastroAssn @MJWhitsonMD @IssakaMD @DrLorenGR @MayoClinicGIHep @DougSimonetto @IrisWangMD I liked the example of wearing a button to clinic embroidered with the phrase, "ask me about my research." Clever way to bring up the idea while giving patients the agency to initiate further discussion.
