Background: There are no prospective trials comparing the two main reconstructive options after colectomy for Ulcerative colitis, ileal pouch anal anastomosis and ileorectal anastomosis. An attempt on a randomized controlled trial has been made but after receiving standardized information patients insisted on choosing operation themselves., Methods: Adult Ulcerative colitis patients subjected to colectomy eligible for both ileal pouch anastomosis and ileorectal anastomosis are asked to participate and after receiving standardized information the get to choose reconstructive method. Patients declining reconstruction or not considered eligible for both methods will be followed as controls. The CRUISE study is a prospective, non-randomized, multi-center, open-label, controlled trial on satisfaction, QoL, function, and complications between ileal pouch anal anastomosis and ileorectal anastomosis., Discussion: Reconstruction after colectomy is a morbidity-associated as well as a resource-intensive activity with the sole purpose of enhancing function, QoL and patient satisfaction. The aim of this study is to provide the best possible information on the risks and benefits of each reconstructive treatment., Trial Registration: ClinicalTrials.gov Identifier: NCT05628701., (© 2023.

Aim: Reconstructive surgery with ileal pouch-anal anastomosis (IPAA) is the standard procedure after colectomy in patients with Ulcerative Colitis (UC) and Familial Adenomatous Polyposis (FAP). It is of interest to understand how a generation shift of the surgeons performing IPAA has affected patients' outcomes., Method: All consecutive patients who underwent IPAA in the period 1999-2016 at Sahlgrenska University Hospital/Östra, Gothenburg, Sweden, were included. Surgeons representing two different generations performed the surgeries during this period. The following 6-year time periods were assigned for surgeries performed by: experienced surgeons (1999-2004; Period 1); the new generation of surgeons undergoing training (2005-2010; Period 2); and the new generation of experienced surgeons (2011-2016; Period 3). The primary endpoint was post-operative complications (Clavien-Dindo ≥3b), and the secondary endpoints were the functional outcome, failure of the pouch, and mortality. Logistic analyses of the results were performed., Results: Overall, 281 patients were included in the study. The rate of post-operative severe complications was lower in Period 1 [Odds Ratio (OR) 0.137; p  = .01]. There was no difference in functional outcome between the groups., Conclusion: This study implicates that the risk of post-operative complications after IPAA is lower when the surgery is performed by a generation of more-experienced surgeons. This might support literature that concludes that surgical units that have a high throughput of patients and are staffed by surgeons who perform many procedures provide better outcomes.

Background: The standard treatment for Hinchey III perforated diverticulitis with peritonitis was resection with or without a stoma, but recent trials have shown that laparoscopic lavage is a reasonable alternative. This registry-based Swedish study investigated results at a national level to assess safety in real-world scenarios., Methods: Patients in Sweden who underwent emergency surgery for perforated diverticulitis between 2016 and 2018 were studied. Inverse probability weighting by propensity score was used to adjust for confounding factors., Results: A total of 499 patients were included in this study. Laparoscopic lavage was associated with a significantly lower 90-day Comprehensive Complication Index (20.9 versus 32.0; odds ratio 0.77, 95 per cent compatibility interval (c.i.) 0.61 to 0.97) and overall duration of hospital stay (9 versus 15 days; ratio of means 0.84, 95 per cent c.i. 0.74 to 0.96) compared with resection. Patients had 82 (95 per cent c.i. 39 to 140) per cent more readmissions following lavage than resection (27.2 versus 21.0 per cent), but similar reoperation rates. More co-morbidity was noted among patients who underwent resection than those who had laparoscopic lavage., Conclusion: Laparoscopic lavage is safe in routine care beyond trial evaluations., (© The Author(s) 2021.

Introduction: Whether data on International Classification of Diseases (ICD)-codes from the Swedish National Patient Register (NPR) correctly correspond to subtypes of inflammatory bowel disease (IBD) and phenotypes of the Montreal classification scheme among patients with prevalent disease is unknown. Materials and methods: We obtained information on IBD subtypes and phenotypes from the medical records of 1403 patients with known IBD who underwent biological treatment at ten Swedish hospitals and retrieved information on their IBD-associated diagnostic codes from the NPR. We used previously described algorithms to define IBD subtypes and phenotypes. Finally, we compared these register-generated subtypes and phenotypes with the corresponding information from the medical records and calculated positive predictive values (PPV) with 95% confidence intervals. Results: Among patients with clinically confirmed disease and diagnostic listings of IBD in the NPR ( N  = 1401), the PPV was 97 (96-99)% for Crohn's disease, 98 (97-100)% for ulcerative colitis, and 8 (4-11)% for IBD-unclassified. The overall accuracy for age at diagnosis was 95% (when defined as A1, A2, or A3). Examining the validity of codes representing disease phenotype, the PPV was 36 (32-40)% for colonic Crohn's disease (L2), 61 (56-65)% for non-stricturing/non-penetrating Crohn's disease behaviour (B1) and 83 (78-87)% for perianal disease. Correspondingly, the PPV was 80 (71-89)% for proctitis (E1)/left-sided colitis (E2) in ulcerative colitis. Conclusions: Among people with known IBD, the NPR is a reliable source of data to classify most subtypes of prevalent IBD, even though misclassification commonly occurred in Crohn's disease location and behaviour and also among IBD-unclassified patients.

Aim: The aim of this study was to investigate if a delay in a patient's first contact with a healthcare professional, and any subsequent delay in diagnosis, affected self-assessed quality of life prior to start of treatment for rectal cancer., Method: Questionnaires were administered when patients had been informed of the diagnosis and planned treatment. The primary end-point was self-assessed quality of life according to a seven-point Likert scale. The response variables were dichotomized and analysed by unadjusted and adjusted binary logistic regression., Results: A reported duration of symptoms longer than 4 months was found to be associated with a lower quality of life than a reported duration of symptoms of less than 3 months. Furthermore, a reported period of longer than 2 months from first contact with a healthcare professional to a diagnosis was found to correlate with lower quality of life compared with a period shorter than 2 months. However, when adjusting for possible confounding variables the duration of symptoms and time to diagnosis were not found to affect self-assessed quality of life. Several variables were found to have significant influence in the statistical model, including sense of coherence, the presence of negative intrusive thoughts, comorbidity, depressed mood, male sex and comorbidity., Conclusion: One conclusion of our study is that further efforts to shorten delay in rectal cancer care with the aim of improving quality of life may be futile. To improve the patient's quality of life at diagnosis other interventions should be considered, such as screening for depression and/or negative intrusive thoughts., (© 2017 The Authors.

Objective: Patients who undergo ileal pouch-anal anastomosis (IPAA) after colectomy for ulcerative colitis (UC) occasionally have neoplasia in the IPAA. Patients with evidence of dysplasia or carcinoma in the colorectal specimen may have an increased risk of such neoplasia. A surveillance program has been suggested. The aims of this study were to evaluate the outcomes of surveillance of a large patient cohort, and to investigate the prevalences of neoplasia in the ileal pouch mucosa and in the anal transitional zone (ATZ)., Material and Methods: A total of 629 patients underwent IPAA for UC at Sahlgrenska University Hospital, Gothenburg, Sweden. Identified from a register, 73 patients with neoplasia in their specimen considered eligible for the trial were prospectively enrolled, and underwent clinical examination, endoscopy with macroscopic evaluation, and mucosal biopsies from the ileal pouch and the ATZ. The biopsies were independently evaluated by two experienced gastro-pathologists., Results: In all, 56 patients (39 males) with a median follow-up time of 18 (range, 1-29) years were evaluated. One patient (1.8%; 95% CI 0%-5.3%) showed low-grade dysplasia in the pouch, as recorded by one of the two pathologists. The individual pathologists recorded indefinite for dysplasia (IFD) in the pouch for 19 and 20 patients, respectively, and IFD in the ATZ for 2 and 4 patients, respectively. None of the biopsies showed evidence of high-grade dysplasia (HGD) or carcinoma., Conclusions: Neoplasia in the ileal pouch or ATZ after IPAA for UC is rare in the proposed risk group. The necessity for and value of a routine surveillance program should be prospectively evaluated.

Effects of pH and concentrations of Cl and Ca on the uptake of methyl mercury (MeHg) in the gills of the minnow (Phoxinus phoxinus) were studied. Chloride concentration and pH in the water affect the speciation of MeHg. Ca was included because it affects the permeability of the gills and could therefore indirectly affect the amount of MeHg accumulated in the tissue. The species formed differ in hydrophobicity, as reflected in their octanol/water partition coefficients (Pow). Both a reduction in pH and an increase in Cl- concentration increased the Pow of MeHg. Ca had no effect on speciation. The accumulation of MeHg in the gill tissue increased with decreasing pH (from pH 7.0 to pH 3.9). Accumulation also increased as Cl- concentrations were increased from 10(-7) to 10(-1) M at pH 7.0. An increase in Ca concentration did not alter the accumulation of MeHg beyond a decrease in MeHg accumulation as Ca increased from 20 to 50 microM. We conclude that, of the water-quality factors studied, those affecting chemical speciation were most important in determining the MeHg uptake. The Ca concentration appears to be of minor importance.
