Writing on Instagram, the 46-year-old, who is married to reality star Kourtney Kardashian, said he had gone to hospital for an endoscopy on Monday “feeling great”. “But after dinner, I felt excruciating pains and have been in hospital ever since. “During the endoscopy, I removed a very small polyp right in a very sensitive area, usually handled by specialists, which unfortunately damaged a critical pancreatic drainage tube. “This resulted in severe life-threatening pancreatitis.” She added: “I am so very very grateful that with the intensive treatment I am now much better.” Last Tuesday, Barker was seen being taken to Cedars-Sinai Medical Center in Los Angeles on a stretcher. At his side was a black tracksuit Kardashian, 43. On Thursday, Alabama Barker’s 16-year-old daughter shared a photo on Instagram of her hand next to her father’s – showing off the signature tattoo. The post was accompanied by the caption: “Thank you guys for all the prayers and love, I appreciate and love you all.”
