Background
Causes
- Radiation treatment
- Autoimmune
- Vasculitis
- Ischemia
- Infectious (STI and enteric organisms)
Clinical Features
- Inflammation of the rectal mucosa
- Pain on defecation
- Tenesmus
- Mucoid discharge
- Inguinal lymphadenopathy (may be seen with T. pallidum)
Differential Diagnosis
Anorectal Disorders
- Anal fissure
- Anal fistula
- Anal malignancy
- Anal tags
- Anorectal abscess
- Colorectal malignancy
- Condyloma acuminata
- Constipation
- Crohn's disease
- Cryptitis
- GC/Chlamydia
- Hemorrhoids
- Pedunculated polyp
- Pilonidal cyst
- Proctitis
- Pruritus ani
- Rectal foreign body
- Rectal prolapse
- Syphilitic fissure
Evaluation
Condyloma Acuminata
Gonorrhea
- Symptoms vary from none to severe rectal pain with yellow, bloody discharge
- Unlike nonvenereal cryptitis, infection is not confined to the posterior crypt
- Diagnosis made by Gram stain and culture
- Also consider dissemination to heart, liver, CNS, and joints
Chlamydia
- Infection due to direct anorectal infection or via vaginal seeding to perirectal lymphatics
- Symptoms range from asymptomatic to anal pruritus, pain, purulent discharge
- Lymphogranulomatous variety
- Acutely painful anal ulcerations associated with unilateral lymph node enlargement
- Fever and flulike symptoms
- May result in rectal scarring, stricturing, perirectal abscesses, chronic fistulas
Syphilis
- Primary
- Anal chancres appear ~2-6 weeks after intercourse, are often painful
- May be misdiagnosed as simple fissure
- Symmetric lesion on opposite side of anal margin is distinguishing feature
- Inguinal adenopathy is often present
- May be misdiagnosed as simple fissure
- Anal chancres appear ~2-6 weeks after intercourse, are often painful
- Secondary
- Condylomata lata (flatter and firmer than condylomata acuminata)
Herpes Simplex Virus-2
- Itching and soreness in perianal area progressing to severe anorectal pain
- Accompanied by flulike illness, inguinal adenopathy
- Early lesions are small, discrete vesicles on erythematous base
- Vesicles then enlarge, coalesce, and rupture, forming exquisitely tender ulcers
Management
Presumed GC/chlamydia of cervix, urethra, or rectum (uncomplicated)[1]
Typically, treatment for both gonorrhea and chlamydia is indicated, if one entity is suspected.
Standard
- Gonorrhea
- Ceftriaxone IM x 1
- 500 mg, if weight <150 kg
- 1 g, if weight ≥150 kg
- Ceftriaxone IM x 1
- Chlamydia
- Nonpregnant: doxycycline 100 mg PO BID x 7 days
- Pregnant: azithromycin 1 g PO x 1
Ceftriaxone contraindicated
- Gonorrhea
- Gentamicin 240 mg IM x 1 PLUS azithromycin 2 g PO x 1, OR
- Cefixime 800 mg PO x 1
- Chlamydia^
- Nonpregnant: doxycycline 100 mg PO BID x 7 days
- Pregnant: azithromycin 1 g PO x 1
^Additional chlamydia coverage only needed if treated with cefixime only
Partner Treatment
- Gonorrhea
- Cefixime 800mg PO x 1
- Chlamydia
- Nonpregnant: doxycycline 100mg PO BID x 7 days, OR
- Pregnant: azithromycin 1g PO x 1
Syphilis
- Penicillin G 2.4mil IM x1
Herpes Simplex Virus-2
- Acyclovir 400mg PO TID x10d for initial episode; 800mg TID x2d for recurrent episodes
