In 2007 he joined the Costa del Sol Hospital and left this position when he obtained an international scholarship that would take him back to San Francisco. In 2010 he moved to Japan to complete his training in the submucosal endoscopic dissection technique that he would later on introduce in Andalusia in 2011, thus becoming one of the pioneers in the performance of this technique in Spain. In 2011 he became the first medical professional in the world to use the 15-mm AXIOS stent in pancreatic fluid collection drainage. In 2018 he began to perform gastroenteroanastomosis with luminal apposition stent in patients with pancreatic cancer and bowel obstruction, thus becoming a pioneer in Andalusia to perform such technique.
He is a coauthor of the reference guides of the European Society of Gastrointestinal Endoscopy on the endoscopic treatment of chronic pancreatitis and non-variceal gastrointestinal haemorrhage.
