Rectal Examination o Anatomy I oThe rectum is the curved lower, terminal segment of large bowel. oIt is about 12 cms long and runs along the concavity of the sacrum. oAnterior to the lower 1/3 of the rectum lie different structures in men and women Anatomy II oIn men, anterior to the lower 1/3 of the rectum lie the prostate, bladder base and seminal vesicles. oIn women, anterior to the lower 1/3 of the rectum lies the vagina. At the tip of the examining finger it may be possible to feel cervix and even a retroverted Uterus When is it done? oThis is an intimate and sometimes uncomfortable examination which is most often done when disease (usually gastrointestinal or genitourinary disease) is suspected or already identified. oIt may also be done as part of a screening examination when there is no suspicion or expectation of disease but the examination is performed as part of a thorough screening process. oIt is important in all cases to explain the reasons for the examination and to get verbal consent. Indications for R.E. oAssessment of the prostate (particularly symptoms of outflow obstruction). oWhen there has been rectal bleeding (prior to proctoscopy, sigmoidoscopy and colonoscopy). oConstipation. oChange of bowel habit. oProblems with urinary or faecal continence. oIn exceptional circumstances to detect uterus and cervix (when vaginal examination is not possible). Procedure oThe finger is then moved through 180°, feeling the walls of the rectum. oWith the finger then rotated in the 12 o'clock position, helped usually by the examiner bending knees in a half crouched position and pronating the examining wrist, the anterior wall can be palpated. oRotation facilitates further examination of the opposing the walls of the rectum. In men, the prostate will be felt anteriorly. In women, the cervix and a retroverted uterus may be felt with the tip of the finger. oIt is important to feel the walls of the rectum throughout the 360°. Small rectal wall lesions may be missed if this is not done carefully. Examination of the Prostate Gland o oNormal size is 3.5 cms wide, protruding about 1 cm into the lumen of the rectum. oConsistency: it is normally rubbery and firm with a smooth surface and a palpable sulcus between right and left lobes. oThere should not be any tenderness. oThere should be no nodularity. ohttp://beta.medicalvideos.us/videos-354-Rectal-Examinations o ohttp://beta.medicalvideos.us/videos-2539-Proctoscope-Medical-Examination-of-the-Rectum External Inspection o oSkin disease. oSkin tags oGenital warts oAnal fissures oAnal fistula oExternal haemorrhoids oRectal prolapse oSkin discolouration with Crohn's disease oExternal thrombosed piles Internal Inspection oSimple piles (but best examined at proctoscopy) oRectal carcinoma oRectal polyps oTenderness oDiseases of the prostate gland oMalignant or inflammatory conditions of the peritoneum (felt anteriorly) Contraindications oImperforate Anus oUnwilling patient oImmunosuppressed patient oAbsence of anus following surgical excision oStricture oModerate to severe anal pain oProlapsed thrombosed internal hemorroids oTHANKS FOR LISTENING ‹#› 21
