Treatment Options for Perianal Bowen's Disease: Survery of American Society of Colon and Rectal Surgeons Members

The aim of this study was to determine current management practices of physicians caring for patients with perianal Bowen's disease. A questionnaire was sent to 1,499 members listed in the 1997 American Society of Colon and Rectal Surgeons Directory asking them how many patients they have treated and which operative or nonoperative treatment option they choose for small (< or =3 cm), large (> 3 cm), and microscopic lesions. Of 1,499, 663 (44.2%) surgeons responded. Not all respondents answered each item. Seventy-five per cent of surgeons surveyed (n = 653) devote greater than 75 per cent of their practice to colon and rectal surgery. Of 642 respondents, 552 (86%) managed a total of <10 patients, and 90/642 (14%), > or =10 patients. Ninety-six per cent of respondents use wide local excision for patients with small lesions. Eighty-seven per cent of respondents use wide local excision for patients with large lesions. Seventy-four per cent treat patients with microscopic disease conservatively and without wide excision. The majority of surgeons caring for patients with perianal Bowen's disease are performing wide local excision for both small and large lesions. Microscopic disease was usually treated conservatively with observation alone.
