Professor Didier Mutter delivers a lecture on how to prevent, diagnose and treat most common complications occurring in laparoscopic colorectal surgery. The talks, enriched by numerous endoscopic videos, didactically classify complications by the surgical phase in which those are more likely to occur. Besides talking frankly about events that most surgeons are ashamed to speak about, professor Mutter gives a handful of practical tips and tricks on how to prevent and treat those occurrences.
