Ano-Rectal Abscess
Definition
Ano-rectal abscess is a collection of pus that forms in the tissue of the anus or rectum, often due to a bacterial infection.
Types
- Cryptoglandular abscess: The most common type, resulting from a bacterial infection in the anal glands.
- Perianal abscess: A collection of pus that forms near the anus.
- Pelvic abscess: A collection of pus that forms in the pelvic region.
Etiopathogenesis
- Bacterial infection: The most common cause of ano-rectal abscesses, often due to E. coli, Streptococcus, or Staphylococcus.
- Anal gland obstruction: Blockage of the anal glands can lead to bacterial growth and infection.
- Hematogenous spread: Bacteria can spread to the ano-rectal region through the bloodstream.
Clinical Features
- Pain: Severe pain in the anus or rectum.
- Swelling: Swelling and redness in the affected area.
- Fever: Elevated body temperature.
- Discharge: Pus or blood may be discharged from the anus.
- Constipation: Difficulty passing stool.
Investigations
- Physical examination: A thorough examination of the anus and rectum.
- Imaging studies: CT or MRI scans to confirm the presence of an abscess.
Complications
- Fistula: A chronic condition where a channel forms between the anus and the skin.
- Fecal incontinence: Loss of control over bowel movements.
- Chronic pain: Persistent pain in the anus or rectum.
Management
- Drainage: Surgical drainage of the abscess is often necessary.
- Antibiotics: Antibiotics may be prescribed to treat underlying bacterial infections.
- Supportive care: Rest, hydration, and pain management.
Surgical Drainage
- Step 1: The patient is given general anesthesia and positioned in a lithotomy position.
- Step 2: A circumferential incision is made around the abscess, allowing for drainage.
- Step 3: The abscess is drained, and any necrotic tissue is removed.
- Step 4: The wound is dressed and the patient is monitored for postoperative complications.
Postoperative Care
- Pain management: Pain relief medication is prescribed to manage postoperative pain.
- Wound care: The wound is dressed and monitored for signs of infection.
- Return to normal activities: Patients are advised to avoid heavy lifting and strenuous activities for several weeks.
Lymphatic Drainage
- Lymphatic vessels: The ano-rectal region has a rich supply of lymphatic vessels.
- Lymph node involvement: Infection can spread to nearby lymph nodes, leading to inflammation and abscess formation.
