Evaluación de los resultados de la anastomosis ileo-pouch anal o ileo-rectal en pacientes con UC/PSC

Primary sclerosing cholangitis (PSC) is characterised by inflammation and fibrosis of the biliary tree and the condition can lead to end-stage liver disease. PSC is strongly associated with inflammatory bowel disease (IBD), with a prevalence of IBD in PSC as high as 60-84 % in Northern Europe and North America. The majority of patients with IBD and PSC have ulcerative colitis (UC). Considering all patients with UC, around 30% will ultimately require surgery; the most common indications are acute colitis, chronic refractory disease or colorectal dysplasia. The standard procedure is proctocolectomy and ileal pouch-anal anastomosis (IPAA). However, ileo-rectal anastomosis (IRA) or conventional ileostomy are options. The prognosis after surgery is generally considered good. Previous studies have shown that the course of colitis in patients with UC/PSC is different from that of patients with UC-only. In a patient with UC, several aspects have to be considered at counselling before surgery. However, in many aspects, the literature is substantial for patients with UC-only (for example function and quality of life after IPAA) and key information can be safely provided. Conversely, patients with UC/PSC that require colectomy are rare and as a consequence, data on most aspects is sparse (18-20). The aim of the study was to assess outcome after surgery (IPAA or IRA) in patients with UC/PSC. Focus was on pouch/rectal function, pouchitis, surgical complications and failure. Patients with UC-only were employed as controls.
