Failed ERCP after liver transplant, PTCD in place: what would you do?
Post-transplant. Failed ERCP. A PTCD is already in. A 2-minute case from my bile duct strictures lecture. Watch the case, pick your move, then see what we did. This is a very tough stricture. The patient has already been through multiple ERCPs. A PTCD is in place. The endoscopic attempt still failed on the left…...
Extreme ERCP: getting a duodenoscope through a closed esophagus
A 3-minute guide to extreme ERCP: when the duodenoscope cannot pass the esophagus, build a bridge with an overtube and let a balloon scout the way. Some ERCPs fail before the scope reaches the papilla. In this clip from his Extreme ERCP lecture, Klaus Mönkemüller defines a level V ERCP, then shows a patient with…...
Massive hematemesis the day after a Whipple: what would you do?

Bleeding on the right, channel on the left: what would you do?
Your channel is on the left. The bleeder is on the right. A 2.5-minute case from my upper GI bleeding lecture. Watch the case, pick your move, then see what we did. This is the bleed that makes a night call long. The vessel is in view. The needle is out. It will not go…...
Short-stem clips for post-sphincterotomy bleeding
Close the vessel, not the papilla. Short stem. Sheath stays on. 11 mm on the vessel. Leave the orifice open. Post-sphincterotomy bleeding is a small vessel on the edge of a cut you still need. A long stem hangs on the elevator. A wide jaw closes the papilla. Look at the clip on the table…...

Prague C and M: a 7-minute Barrett length guide
A 7-minute guide to Prague C and M: find the tongues, measure circumferential and maximal extent at the incisors, then plan Seattle biopsies. If the next endoscopist opens your note and only sees “short Barrett” or “long tongues,” can they reconstruct the segment? Prague C and M is the shared language: C is circumferential extent,…...
Cap-Assisted Hemostasis: Circular Cap, Load-and-Pull, Then Target
A 5-minute guide to cap-assisted hemostasis: circular distal cap, load-and-pull the clip, then target. A bleeding vessel in the duodenal bulb is hard to face with a bare gastroscope tip. Visualization, stability, and suction-trap of the vessel are weaker without a cap. A pyramidal cap can trap the clip on the way in. In this…...
Esophageal Stricture Dilation: Wire Rules, the Flipped Wire Technique, and the Rule of Three
A 7-minute guide to safe esophageal stricture dilation: read the wire, pass the stricture under control, and stop by rule, not by ambition. You are looking at a tight esophageal stricture. The lumen is a pinhole and you cannot see what lies beyond it. The wire is in your assistant’s hand. Do you advance it…...
Endoscopic Foreign Body Removal: Timing, Tools, and Technique

KAR Hybrid ESD-EMR: Circumferential Tip-of-Snare Incision
A 6-minute guide to knife-assisted resection (KAR): circumferential tip-of-snare incision, then snare lift for hybrid ESD-EMR. Piecemeal EMR on a broad lateral spreading tumor often leaves you guessing about lateral margins. Full ESD is elegant, but not every unit needs a dedicated knife for every flat lesion. Knife-assisted resection (KAR), also called hybrid ESD-EMR or…...
