# Proctoscopy

Proctoscopy

Proctoscopy , performed with the patient in the same position, allows a detailed inspection of  the distal rectum and anal canal ( Figure 80.4 ). Minor procedures can also be carried out through this instrument, e.g. treatment of  haemorrhoids by injection or banding (see Haemorrhoids ) and biopsy . Asking the patient to bear down on slow withdrawal of  the procto scope may reveal a descending intussusception.
