Its incidence increases when associated to inflammatory bowel disease. Persistent sinus is observed in 3-69% of cases. There are various etiological factors associated with this complication; preoperative radiotherapy is the most important. There are various techniques using muscle flaps that can create conditions for closing the persistent perineal sinus. Gracilis muscle flap is a simple technique with good results. Case report: Male, 66 years old, underwent radio and chemotherapy neoadjuvant followed by an abdomino-perineal resection in November 2007 due to an extraperitoneal rectal cancer involving the anal canal to dentate line. A postoperative infected seroma was noted, which was drained, resulting in persistent sinus. Operation to closure the sinus is below described. Comments: Use of gracilis muscle flap is a good option for treat persistent perineal sinus. It can be accomplished by general surgeons with good results. Keywords: abdomino-perineal excision of rectum, chronic perineal sinus, Gracilis muscle flap. %U https://revista.spcir.com/index.php/spcir/article/view/358 %J Revista Portuguesa de Cirurgia %0 Journal Article %P 33-39%N 28 %@ 2183-1165 %8 2014-03-21
