Anal Discomfort (Anorectal Pain): Examination

A comprehensive clinical examination is the basis for selecting further diagnostic steps:

  • General physical examination – including blood pressure, pulse, body temperature, body weight, body height; furthermore:
    • Inspection (viewing).
      • Skin, mucous membranes and sclerae (white part of the eye).
      • Abdomen (abdomen)
        • Shape of the abdomen?
        • Skin color? Skin texture?
        • Efflorescences (skin changes)?
        • Pulsations? Bowel movements?
        • Visible vessels?
        • Scars? Hernias (fractures)?
      • Anal region/anal canal [redness?, swelling, nodule?, lobule?, prolapsed tissue?, prallelastic nodule perianally (usually pinhead- to plum-sized), bluish-red; at anal margin or in anal canal?, blood?, ulcer in anoderm (ulcer in anal mucosa area)?]
    • Palpation (palpation) of the abdomen (abdomen) (tenderness?, knocking pain?, coughing pain?, defensive tension?, hernial orifices?, kidney bearing knocking pain?)
    • Digital rectal examination (DRU): examination of the rectum (rectum) in relation to sphincter function (sphincter function):
      • At rest and under pinch the sphincter ani internus muscle.
      • When actively pinching, the puborectal sling, the sphincter ani externus muscle, as well as the pelvic floor and anal canal length.

      Palpating the anal verge/after area (documentation of findings according to clock time position) Furthermore, the examination of adjacent organs with the finger by palpation [anorectal diseases such as tumors, anal or rectal prolapse (prolapse of the rectum) or rectoceles / ejection of the anterior wall of the rectum into the vagina].

  • Cancer screening

Examination findings and their differential diagnoses.

Findings Differential diagnosis

  • Higher grade hemorrhoids
  • Anal vein thrombosis
Prolapsed tissue
  • Higher grade hemorrhoids
  • Hypertrophied anal papillae
  • Rectal prolapse (prolapse of the rectum)
Weak sphincter tone
