  More info

  We describe a rare case of a 60-year-old man with known history of peptic ulcer disease who presented with melena and epigastric pain secondary to coil migration into duodenal mucosa 4 years after the initial therapeutic embolisation of the gastroduodenal artery. Upper endoscopy revealed oozing duodenal ulcer at the same site of the previously located duodenal ulcer 4 years ago and metal coil impacted at the duodenal mucosa. It is unclear if the coil migration is the effect or the cause of the bleeding duodenal ulcer. Our patient was treated by surgical intervention due to failed endoscopic haemostasis and medical management.

  More info

  We describe a rare case of a 75-year-old woman with significant non-steroidal anti-inflammatory drug (NSAID) use who presented with haematemesis. Upper endoscopy revealed a large (9 cm) intramucosal dissection of the oesophagus without extension into the gastro-oesophageal junction and a severely narrowed pylorus. We postulate that she developed pyloric stenosis due to peptic ulcer disease from chronic NSAID use. This then led to gastro-oesophageal reflux. Undigested pills in the refluxate had contacted oesophageal mucosa, leading to pill-induced oesophageal injury. This, along with vomiting, is postulated to have led to the oesophageal intramucosal dissection. She improved with conservative medical management with a clear liquid diet and proton pump inhibitors, and a follow-up upper endoscopy 1 week later showed recovery of the previously seen intramucosal dissection.

  Left ventricular outflow tract (LVOT) obstruction and paravalvular leak (PVL) are relatively uncommon, but are serious complications of prosthetic valve replacement.
