Flexible sigmoidoscopy

author/s: Dr Javier Nebreda Duran

This technique consists in introducing a thin tube with a light through the rectum for about 60 cm to look for polyps, anormal areas and cancer. This technique allows the clinician to diagnose over half of all colon cancers and to take biopsy samples of tissue, if necessary.

 

Does it have any added advantages?

Virtual colonoscopy not only enables visualisation of the lumen of the colon but also visualisation of the outer wall of the intestine, its thickness, control of adenophaties and the rest of abdominal organs.

It also permits the visualisation of lesions that will be subsequently treated via endoscopy or surgery.
