Abstract
Altered microbiota and impaired host immune function have been linked to the pathogenesis of pouchitis. We used 16S rRNA gene sequencing and RNA sequencing data from a previous randomized clinical trial (RCT) on fecal microbiota transplantation (FMT) therapy in 26 chronic pouchitis patients with one-year follow-up. We analyzed changes in both luminal and mucosal microbiota composition, as well as in host mucosal gene expression to gain insights into the host-microbiota interactions possibly underlying clinical outcomes of the patients. Antibiotic type and pattern of use were significant drivers of the luminal microbiota at baseline. Differential gene expression analysis indicated transition from ileal to colonic gene expression in the pouch, and upregulation in inflammation- and immune system-related pathways in the pouch. At 4 weeks, the non-relapsed FMT patients had a lower microbiota dissimilarity to the donor than the non-relapsed placebo patients (p = .02). While two FMT-treated patients showed a shift toward the donor's microbiota during the one-year follow-up, the overall FMT microbiota modulation effect was low. Patient's luminal and mucosal microbiota profiles were unstable in both FMT and placebo groups. Expression of the chemokine receptor CXCR4 was downregulated at 52 weeks compared to the baseline in the non-relapsed patients in both FMT and placebo groups. Microbiota modulation by FMT seems to be low in this patient group. The microbiota composition or alterations did not explain the relapse status of the patients. Some evidence for remission-related host gene expression pattern was found; specifically, CXCR4 expression may have a role in sustained remission.

Abstract
BACKGROUND In ulcerative colitis, a pouchitis is the most common long-term adverse effect after proctocolectomy and ileal pouch-anal anastomosis. Approximately 5% of patients develop chronic antibiotic-dependent or antibiotic-refractory pouchitis without any effective treatment. The aim of this trial was to investigate the efficacy and safety of fecal microbiota transplantation in the treatment of chronic pouchitis. METHODS This was a single-center, double-blinded, parallel group trial comparing donor fecal microbiota transplantation with placebo (autologous transplant) in chronic pouchitis. Twenty-six patients were recruited at the Helsinki University Hospital between December 2017 and August 2018 and were randomly allocated a 1:1 ratio to either donor fecal microbiota transplantation or placebo. The protocol included 2 transplantations into the pouch on weeks 0 and 4, and patients were followed up for 52 weeks. RESULTS Nine patients in the intervention group and 8 patients in the placebo group relapsed during the 52-week follow-up, and the relapse-free survival did not differ between the groups (P = 0.183, log-rank; hazard ratio, 1.90 [95% confidence interval, 0.73-4.98; P = 0.190]). In the subgroup analysis of patients using continuous antibiotics before the study, the relapse-free survival was shorter in the intervention group (P = 0.004, log-rank; hazard ratio, 13.08 [95% confidence interval, 1.47-116.60; P = 0.021]). No major adverse effects were reported. CONCLUSIONS The fecal microbiota transplantation treatment regime used in our study was not effective in the treatment of chronic pouchitis. The safety profile of fecal microbiota transplantation was good. CLINICALTRIALS.GOV IDENTIFIER NCT03378921.

Abstract
OBJECTIVES Patients with ulcerative colitis are at increased risk for colorectal cancer, especially at younger ages. Our aim was to determine, in our patient cohort, the clinicopathological features, incidence, and prognosis of ulcerative colitis-associated colorectal cancer. MATERIALS AND METHODS A single-center, population-based study including all 1241 patients with ulcerative colitis who underwent surgery in Helsinki University Hospital, 1991-2018. All data were from medical records, collected retrospectively. RESULTS In total, 71 patients with ulcerative colitis-associated cancer were operated on in Helsinki University Hospital during 1991-2018; 108 patients undergoing surgery during 2002-2018 showed dysplasia in the surgical specimen. Cancer was diagnosed preoperatively in 47 patients (66.2%). Ten patients (14.1%) had synchronous colorectal cancer, and 24 (33.8%) had synchronous dysplasia. The incidence of colorectal cancer has not changed during the study period (p = .113). Overall survival was 71.8%, and the 5-year colorectal cancer-specific survival was 81.5%. CONCLUSION The incidence of ulcerative colitis-associated colorectal cancer remained constant in our study population over three decades. The prognosis of ulcerative colitis-associated colorectal cancer and the prognosis of sporadic colorectal cancer were comparable. One-third of the cancers were not diagnosed in preoperative colonoscopy, and the indication for surgery in such cases was dysplasia. We therefore do not recommend the endoscopic management of ulcerative colitis-associated dysplasia.

Abstract
BACKGROUND AND AIMS Patients with ulcerative colitis are often treated with multiple immunomodulative agents to achieve remission. In refractory disease, the next option is frequently proctocolectomy with ileal pouch-anal anastomosis. No consensus exists as to whether immunomodulatory therapy at the time of ileal pouch surgery leads to any increase in postoperative complications. Our aim was to assess, in ulcerative colitis patients with restorative proctocolectomy, the effect of preoperative anti-tumor necrosis factor therapy and corticosteroids on postoperative complications and pouch failure. MATERIALS AND METHODS A retrospective medical record review of 445 patients with ulcerative colitis who underwent proctocolectomy with ileal pouch-anal anastomosis in Helsinki University Hospital between January 2005 and June 2016. RESULTS Anti-tumor necrosis factor agents were not associated with postoperative complications. Only high-dose corticosteroids (prednisolone ⩾20 mg or equivalent) were associated with higher incidence of anastomotic leak (12.6% vs 2.5%, P = 0.002) and wound dehiscence (4.2% vs 0%, P = 0.019), but pouch failure rate was no higher (2.1% vs 0%, P = 0.141) than in patients without corticosteroid treatment. A lower dosage of corticosteroids had no effect on early postoperative complications, but pouch failure rate was increased (4.4% vs 0%, P = 0.015). CONCLUSION Corticosteroids, but not anti-tumor necrosis factor therapy, were associated with postoperative complications. Preoperative use of corticosteroids may increase pouch failure rate, but the risk is still minor in high-volume centers performing ileal pouch surgery.

Abstract
AIM Restorative proctocolectomy with ileal pouch-anal anastomosis is considered by many surgeons to be the standard procedure for surgical management of ulcerative colitis. There is controversy about whether or not a covering ileostomy should be constructed. The aim of this study was to evaluate the outcomes and morbidity for patients with ulcerative colitis who underwent restorative proctocolectomy with or without a diverting ileostomy. METHOD This is a retrospective study of a consecutive series of 510 patients with ulcerative colitis who were operated on in Helsinki University Hospital between January 2005 and June 2016. A diverting ileostomy was performed in 119 patients (the stoma group) compared with 391 patients with no stoma. RESULTS Dehydration and intestinal obstruction occurred more often in the stoma group (P < 0.0001). Clinical anastomotic leakage was more common among patients without an ileostomy (6.6% vs 1.7%, P = 0.04). However, the need for re-laparotomy because of any early complication did not differ between the groups (P = 0.58). Within 3 months, 50 patients with ileostomy (42.0%) and 51 patients without (13.0%) were readmitted (P < 0.0001). In total, 35 patients (29.3%) had a complication relating to ileostomy closure and four of them required surgery. There was no difference in the rate of fistulas, pouchitis or pouch failure between the groups. CONCLUSION Our study shows that a diverting ileostomy is associated with considerable morbidity but it does not seem to prevent later failure of the pouch. We suggest that a diverting ileostomy should only be constructed for high-risk patients.
