Accurate preoperative staging• Location (height)• TNM staging• Free resection Margin TME
Tumour Height MeasurementDecreasing order of reliability???1. Rigid sigmoidoscopy2. Flexible sigmoidoscopy/colonoscopy3. Endorectal ultrasound (can overestimate)4. DRE (low lying tumours)5. CT or MRI
ManagementT1. Transanal ExcisionT2. TMET3. Pre-op Chemo-rad + TME Vs TME + Post-op Chemo-rad T 4 • Pre-op Chemo-rad +Exenteration.
MRI AccuracyT Staging : 71-91 %N Staging : 43-85 %CRM : 95 %Highest Accuracy and Consistency.
Summary.
Thank You.
