So exciting to welcome back @MagnusHallandMD as a guest speaker to kick off our @MayoClinicGIHep fellows summer core curriculum! The packed house with rapt attention is a clear testament to his teaching reputation & excellent delivery!

@IrisWangMD @MayoClinicGIHep Lovely to come back and great fellows!

Our group was the first to define POSED (Post-Obesity Surgery Esophageal Dysfunction), a newly recognized motility disorder that can develop in a subset of patients after metabolic bariatric surgery. In our latest @NGMJournal Neurogastroenterology & Motility study, we uncover a potential mechanism: 🔹 Low proximal gastric distensibility and elevated post-swallow intragastric pressure increase esophageal afterload 🔹 This leads to secondary peristalsis abnormalities, eventually progressing to primary motor dysfunction (resembling achalasia) 🔹 70% had abnormal FLIP findings despite normal or borderline HRM 📌 Clinical vigilance is key—patients with new-onset dysphagia after bariatric surgery should be evaluated for POSED, even when standard manometry appears normal. Collaborative work with @KarthikRavi @OMGhanemMD @MayoClinicGIHep colleagues. #POSED #EsophagealMotility #BariatricSurgery #Dysphagia #FLIP #GIInnovation #Neurogastroenterology

📌 New Insights into Dyssynergic Defecation by @MayoClinicGIH and Dr. Adil Bharucha •         🔍 Integrated manometry + proctography = Seated proctomanometry •         📊 Proctomanometry redefines our concepts of normal and dyssynergic defecation •         🚻 Most DD patients have both impaired propulsion & relaxation •         🧠 Consider biofeedback therapy guided by manometry gastrojournal.org/article/S0016-… #GIHealth #ConstipationCare #PelvicFloor @AmerGastroAssn

@DrViswanathRed1 Different system to what I use in my lab, but by color reference the pressure zone near the diaphragm and LES it at times same color as UES (typically 80-120 mmHg) - you rarely if ever see those pressures around and the crural diaphragm- suspect calibration or catheter issue

@MagnusHallandMD Shall post the colour reference sir. Could you elaborate on the fault!?

@DouglasAdlerMD Esophageal self dilation after serial endoscopic dilation - many successful treatments

Even in the best of hands, esophagectomy can result in serious trouble for patient. This patient developed a profound anastomotic stricture after esophagectomy. We see these often & dilate, stent, incise, inject, etc. How would you treat this? #thoracic #surgery #gitwitter
