Background: Ileal pouch anal anastomosis (IPAA) to surgically manage ulcerative colitis may involve multiple separate surgical procedures, impacting treatment costs, length of stay in hospital, complication rates and patient outcomes, and there is currently no accepted standard of care regarding the number of stages that should be performed. The purpose of this study was to compare the practice patterns of Canadian and American colorectal surgeons regarding the surgical management of ulcerative colitis. Methods:A questionnaire was mailed to all practisng fellows of the American Society of Colon and Rectal Surgeons (ASCRS) in Canada and the United States. Surgeons were asked to describe their typical practices for 3 clinical scenarios.Results: Questionnaires were mailed to 40 Canadian and 873 American ASCRS fellows with response rates of 86% and 62%, respectively. In the case of a patient who has had a prior colectomy, who is not taking steroids and in whom a tension-free IPAA is possible, 44% of Canadian surgeons would perform IPAA alone and 56% would perform IPAA with a loop ileostomy. In contrast, only 26% of American surgeons would perform IPAA alone and 74% would perform IPAA with a loop ileostomy (p = 0.002). In the case of a patient who has not had previous surgery, who is taking 10 mg/day of prednisone and in whom a tension-free IPAA is possible, the majority of both Canadian and American surgeons would perform an IPAA with a loop ileostomy (93% and 89%, respectively, p = 0.06). In the case of a patient who has not had previous surgery, who is taking 40 mg/day of prednisone and in whom a tension-free IPAA is possible, 45% of Can adian surgeons would perform a subtotal colectomy with an end ileostomy compared with 14% of American surgeons (p < 0.001). Conclusion:There are significant differences in the surgical management of ulcerative colitis between Canadian and American colorectal surgeons.Contexte : L'anastomose iléo-anale avec poche (AIAP) pour traiter chirurgicalement la colite ulcéreuse peut comporter de multiples interventions chirurgicales distinctes, ce qui a un effet sur les coûts du traitement, la durée du séjour à l'hôpital, les taux de complication et les résultats pour les patients. Il n'y a actuellement pas de norme de soins acceptée en ce qui a trait au nombre d'étapes à suivre. Cette étude visait à comparer les tendances de la pratique des spécialistes canadiens et américains de la chirurgie colorectale en ce qui a trait au traitement chirurgical de la colite ulcéreuse. Méthodes :On a envoyé un questionnaire par la poste à tous les associés actifs de la Société américaine des chirurgiens du côlon et du rectum (American Society of Colon and Rectal Surgeons -ASCRS) au Canada et aux États-Unis. Les chirurgiens devaient décrire leur pratique habituelle dans 3 scénarios cliniques.Résultats : Les questionnaires ont été envoyés par la poste à 40 associés canadiens et 873 associés américains de l'ASCRS et les taux de réponse ont atteint 86 % et 62 % respectivement. Dans le cas d'un patient qui a ...
