Introduction  

Surgical treatment of extensive and confluent anal condylomata results in large open wounds, which in other contexts of anorectal surgery (e.g., hemorrhoidectomy), have been associated with a relevant risk of stricture formation. The aim of our study was therefore to revisit the issue and assess this risk and the general morbidity in patients undergoing extensive excision and fulguration of anal warts.

Materials and methods  

Records of 41 consecutive patients undergoing with excision/fulguration of extensive, i.e., >50% confluent anal condylomata were retrospectively reviewed. Excluded were patients with a lesser degree of warts and patients lost to follow-up before complete wound healing. Data recorded included patient characteristics and evolution of the local area after the surgery.

Results  

Forty-one patients (40 males and one female) underwent excision and fulguration of a large anal condyloma with an average follow-up of 6 months (range, 1–36 months). The majority of patients (97.6%) were HIV-positive with 80% taking antiretroviral medication. Half of the patients had not received any previous medical or surgical treatment, whereas one fourth had undergone surgical excisions or fulgurations before. Recurrent warts developed in 19 patients (46.3%). The surgical morbidity after the extensive excision consisted of bleeding (22%). However, none of the patients showed any evidence or complaints of postoperative stricturing and anal stenosis at follow-up.

Conclusions  

Excision of extensive anal condylomata has a known high probability of recurrences, but the risk of developing anal stenosis is low. Careful primary excision of even confluent warts can therefore be safely performed without major primary flap reconstructions.
