Today we are reporting on the 'FLIP device' and give you an update on the likely aetiology of achalasia.  There have been studies on 'motorised spiral enteroscopy'. Is a motor really a good thing inside the small bowel?  We are surprised to see a complete turnaround in the recommendations from Sheffield on how to diagnose Coeliac disease !  Sadly, surveillance in patients with MUTyH related polyposis doesn't seem to save lives.  Should we all start doing 'full thickness' colonic resections?  I urge caution!   Finally, there have been some good news and some bad news on the topic of emergency GI bleeding ...
