Rigid Sigmoidoscopy
Dr.
George Orlay M.B., B.S., F.R.C.S., F.R.A.C.S.
The rigid sigmoidoscope has lost a great deal of value in specialist practice
since the advent of the modern video-colonoscope. In general practice however,
it is especially useful with the younger patient who is bleeding per rectum.
Rigid Sigmoidoscope (Lloyd Davis). A metal
tube with obturator, bellows, and a built-in light source (fibreoptic).
An eyepiece
prevents escape of air. Disposible models are available.
It can of course be used under other circumstances, but it must be realised
that polyps and cancers become more common over the age of 35 and
that the failure to diagnose these conditions above the range of the
rigid sigmoidoscope would be serious both for the patient and the doctor.
Indications for office rigid sigmoidoscopy are:
- Any symptoms or physical sign
which suggests ano-rectal or colonic neoplasia.
- As a routine prior to
ano-rectal procedures.
- In the investigation of inflammatory
rectal disease.
- To obtain biopsy specimens of any bowel condition
within the reach of the instrument.
