Laboratory Studies

  • Hematocrit testing is suggested if excessive bleeding with concomitant anemia is suspected.
  • Coagulation studies are indicated if the history and physical examination suggest coagulopathy.
Next

Imaging Studies

  • Barium enema study or virtual colonoscopy is suggested if proximal colonic and intestinal diseases must be excluded and if endoscopy is not helpful.

Diagnostic Procedures

  • Examination begins with inspection and examination of the entire perianal area. Warn the patient before any probing or poking. Because patient apprehension is great prior to any anal examination, go to great lengths to reassure the patient. Gentle spreading of the buttocks allows easy visualization of most of the anoderm; this includes the distal anal canal. Anal fissures and perianal dermatitis (pruritus ani) are easily visible without internal probing. Note the location and size of skin tags and the presence of thromboses. Normal corrugation of the anoderm and a normal anal wink with stimulation confirms intact sensation. Digital examination of the anal canal can identify any indurated or ulcerated areas. Be sure to palpate the prostate in all men. Because internal hemorrhoids are soft vascular structures, they are usually not palpable.
  • Anoscopy is mandatory for viewing internal hemorrhoids. The anoscope should be a side-viewing one. When angled well by the examiner, the side-viewing anoscope allows the soft hemorrhoidal tufts to fill the beveled end of the scope and to be appropriately evaluated. Prolapse can be observed when the patient performs a Valsalva maneuver. Flexible sigmoidoscopy is performed to exclude proximal disease. Having a patient strain while sitting on a toilet may reproduce prolapse most accurately. Examining patients while they sit on a toilet can be very helpful in indeterminate cases. Colonoscopy, virtual colonoscopy, and barium enema are reserved for cases of bleeding without an identified anal source. These symptoms are not attributable to hemorrhoids and are considered to be non – outlet-type bleeding.

Histologic Findings

Routine histologic examination of hemorrhoidal tissue is usually unrewarding, especially if it is grossly examined by an experienced anorectal surgeon. Any suspicious tissue must be sent for microscopic evaluation. External hemorrhoids are classified by underlying pathology and symptoms, which include thrombosed veins, bleeding from eroded blood clots, and skin tags causing hygiene problems.

Staging

Internal hemorrhoids are grouped into 4 stages, as follows:

  • Stage I - Internal hemorrhoids that bleed
  • Stage II – Internal hemorrhoids that cause bleeding and prolapse with straining but return to their resting point by themselves
  • Stage III - Internal hemorrhoids that bleed and prolapse with straining and require manual effort for replacement into the anal canal
  • Stage IV - Internal hemorrhoids that do not return into the anal canal and are therefore constantly outside
