You have managed to get a coveted spot for advanced interventional endoscopy training. Deep down, you know you are ready for this, and that you have the skill, will and dedication. 1 Nevertheless, you are aware that procedures such as endoscopic retrograde cholangiopancreatography (ERCP), therapeutic endoscopic ultrasound (EUS), endoscopic submucosal dissection or third-space endoscopy are a completely different ball game to your regular upper or lower endoscopies with the odd polyp resected. Advanced endoscopic procedures are associated with a higher and wider range of complications, which are operator dependent, as many studies have shown. Indeed, regarding ERCP, a meta-analysis (13 studies, 59,437 patients) found that complications were less frequent with high-volume endoscopists (odds ratio (OR) ¼ 0.7; 95% confidence interval (CI) 0.5-0.8). 2 A more recent multi-centre study (1191 patients) identified less experienced endoscopists (<200 ERCP procedures) as an independent risk factor for post-ERCP acute pancreatitis (OR ¼ 1.63; 95% CI 1.05-2.53). 3 Moreover, trainees in advanced endoscopy might, according to one study, take more risks and therefore experience higher complication rates compared with fellows in their general gastroenterology training. 4,5 You, like every other advanced endoscopist, will inevitably cause serious complications to your patients, not only in the beginning but throughout your whole career. Keep this in mind and learn how to manage complications, not only with your endoscope but, even more importantly, with good patient communication.
