Proctitis
Background
Causes
- Radiation treatment
- Autoimmune
- Vasculitis
- Ischemia
- Infectious (STI and enteric organisms)
Clinical Features
General
- Inflammation of the rectal mucosa
- Pain on defecation
- Tenesmus
- Mucoid discharge
- Inguinal lymphadenopathy (may be seen with T. pallidum)
By Causative Agent
- 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
- 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)
- Primary
- 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
- Itching and soreness in perianal area progressing to severe anorectal pain
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
- Consider Gram stain and culture
Management
Presumed GC/chlamydia of cervix, urethra, or rectum (uncomplicated)[1]
