Study Notes
Complications of Hemorrhoidectomy
- Post-operative pain can be managed with oral narcotics, NSAIDS, muscle relaxants, topical analgesics, and warm sitz baths.
- Massive bleeding can occur immediately due to inadequate ligation of the pedicle, requiring suture ligation.
- Urinary retention occurs in 10-50% of cases and can be minimized by limiting perioperative IV fluids and providing adequate analgesia.
Stenosis/Stricture
- Scarring after extensive resection of perianal skin can cause stenosis.
- Conservative management includes bowel habit training, bulk forming, and dilatation.
- Mild to moderate strictures can be treated with dilatation.
- Surgical options include stricture release, sphincterotomy, stricturoplasty, and anoplasty.
Anal Fissure
- Anal fissure is a tear in the anoderm distal to the dentate line, often related to trauma from hard stool or prolonged diarrhea.
- Essential features include linear ulcer in the lower half of the anal canal, usually in the posterior midline.
- Characteristic symptoms include tearing pain with defecation, hematochezia, and sensation of intense anal spasm.
- Primary fissure usually occurs in the posterior midline, while primary anterior midline fissure is common in females.
Treatment of Anal Fissure
- ALMORANAS: ask about patient history, signs and symptoms, and risk factors.
- Treatment options include medical therapy, botulinum toxin injection, and lateral internal sphincterotomy.
Hemorrhoidal Disease
- Hemorrhoids are cushions of specialized, highly vascular tissue found within the anal canal in the submucosal space.
- Everyone has hemorrhoids, but they become symptomatic when engorged or enlarged.
- Functions of hemorrhoids include contributing to anal continence and providing sensory information.
- Anatomy includes three main vascular cushions: left lateral, right anterolateral, and right posterolateral.
- Precipitating factors include elevated anal sphincter pressure, aging, and weakened supporting connective tissue.
Classification
- External hemorrhoids: distal 1/3 of anal canal, covered by anoderm, can bleed due to pressure necrosis.
- Internal hemorrhoids: proximal to dentate line, may prolapse or bleed, rarely painful unless thrombosis or necrosis occurs.
Classification of Internal Hemorrhoids
- Grade 1: may protrude into but do not prolapse out of anal canal, painless bleeding.
- Grade 2: prolapse on defecation, reduces spontaneously.
- Grade 3: prolapse, manually reducible, fecal leakage, pruritus ani.
- Grade 4: permanently prolapsed, irreducible.
Indications for Surgical Therapy
- Failure of medical and nonoperative therapy.
- Symptomatic grade III, grade IV, or mixed internal and external hemorrhoids.
- Bleeding from 1st and 2nd degree hemorrhoids improves with dietary fiber and stool softeners.
Complications of Internal Hemorrhoids
- Bleeding from 1st and 2nd degree hemorrhoids.
- Rubber band ligation can cause severe pain if banded distal to the dentate line.
- Urinary retention (1%) is more likely if the internal sphincter is inadvertently included.
- Infection may require debridement, drainage, and antibiotics.
- Bleeding may occur 7-10 days post RBL, usually self-limited.
Acute Thrombosed External Hemorrhoids
- Cause intense pain and a palpable perianal mass during the first 24-72 hours after thrombosis.
- Elliptical excision can be performed in the office under local anesthesia.
- Sitz baths and analgesics are often helpful after 72 hours.
