INTRODUCTION: anorectal procedures consist 80% of surgical cases in colorectal surgery practice. The exact rate of long-term complications after anorectal surgery is unknown. This number is variable according to the medical centres and the type of procedures. OBJECTIVE: to evaluate the long-term complications secondary to anorectal procedures, as well as the risk factors that might be associated with these complications. METHOD: retrospective analysis, including anorectal procedures performed between January 2007 and July 2009. The characteristics analyzed were: sex, age, type of surgery, health system, long-term complications and reoperations performed. RESULTS: 430 patients submitted to 453 anorectal procedures were studied (54,4% female). Hemorrhoidectomy was the most common procedure (50,3% of all operations). The mean period of follow-up was 164,7 days and 102 long-term complications were identified, occurring in 22,52% of all procedures. Residual fissure in ano was the most frequent complication (54%, n=55). Only 38 patients needed reoperation (8,83% of all cases). There was no statistical significance between sex, age, health system and type of surgery in relation to the complications found. CONCLUSIONS: the long-term complication rate was 22,52%, with reoperations performed in 8,83% of all patients. There was no risk factor for long-term complications identified in this case series.
