In a 38-year periodof practice in Coloproctology, the author had the opportunity to attend 34,000patients and the diagnosis of hemorrhoid as the main cause of the symptoms presentedwas achieved in 9,289 patients (27.3%) being hemorrhoid associated with severalanorectal diseases in 1,122 patients (12.1%). 2,417 patients of the patientsunderwent hemorrhoidectomy (26.0%) and 729 of theese patients were operatedon for associated anal diseases at the same time (65.0%). The most frequentlydiagnosed associated anal diseases were anal fissures (541 cases, 5.8%) andhyperthrofied anal papila (312 cases, 3.4%) folowed by anal fistulae (117 cases,1.3%), partial fecal incontinence (112 cases, 1.2%), anal condyloma (37 cases,0,4%) and anal tumors (3 cases, 0,03%). The same order of incidence was verifiedin relation to the 1,122 cases of associated anal diseases: anal fissures (48.2%),hyperthrofied anal papila (27.8%), anal fistulae (10.4%), partial fecal incontinence(10.0%), anal condyloma (3.3%) and anal tumors (0,3%). As far as associatedanal diseases are concerned (1,122 cases), the incidence of surgery was 65.5%(729 patients) in this order: fissurectomy (317 cases, 28.3%), anal papilectomy(267 cases, 23.8%), anal fistulectomy (89 cases, 7.9%), partial fecal incontinence(31 cases, 2.8%), resection of anal condylomata (22 cases, 1.9%), resectionof anal tumors (3 cases, 0.3%). And as far as each associated anal disease isconcerned the incidence of surgery was the following: resection of anal tumors(100,0%), papilectomy (85.6%), fistulectomy (76.0%), resection of anal condylomata(59.6%), fissurectomy (58.6%) and partial fecal incontinence (25.8%). Associatedanal diseases with the highest proportion of confirmation of proctologic diagnosisby the histopathologic examination were anal fistula (100.0% of 89 operatedpatients), anal condyloma (100.0% of 22 operated patients), hyperthrophied analpapilla (79.0% 211 of 267 operated patients), anal fissure (68.5%- 217 of 317 operated patients) and anal cancer (66.7% - 2 of 3 operatedpatients).
