About this event

  • Date and time Fri 6 Sep 2019 from 10:00am to 10:30pm
  • Location Royal Society of Medicine
  • Organised by Coloproctology

This meeting will explore the emerging area of microbiomics. We will look at the impact of microbiomic medicine on colorectal surgical practice, from anastomotic healing to gut dysfunction after bowel surgery and in the pathobiology of colorectal disease. 

We will also discuss controversial areas such as the differences in physiological responses in obese patients after surgery, the use of radiotherapy in rectal cancer and alternatives in surgery for ulcerative colitis.  

We are thrilled to bring together truly world-renowned authorities in Coloproctology, including world experts on the microbiome, Professor John Alverdy and Professor Hans Schardey, renowned authority on advanced rectal cancer, Mr Ian Jenkins and world leaders in colorectal and ileoanal pouch surgery, Professor Conor Delaney and Professor Sue Clark, to name a few. 

Meeting topics: 

  • The role of selective gut decontamination prior to elective bowel surgery and the potential to introduce this in surgical practice to reduce septic complications 
  • Why obese patients may respond differently after surgery
  • The role of radiotherapy in the management of rectal cancer 
  • How to manage the failing ileoanal pouch in ulcerative colitis and alternatives to ileoanal pouch surgery 

This meeting is unique in that it will take place alongside the first-ever reunion of Cleveland Clinic colorectal surgical alumni from the UK and Ireland. With many leaders and opinion formers in colorectal surgery in attendance and plenty of discussion sessions throughout the day, this will be a great networking opportunity.
