  • Chronic non-bloody diarrhoea: a prospective study in Malmö, Sweden, with focus on microscopic colitis.
  • 2014
  • Ingår i: BMC Research Notes. - : BioMed Central (BMC). - 1756-0500. ; 7:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Chronic non-bloody diarrhoea affects up to 5% of the population. Microscopic colitis is one of the most common causes, encompassing the subtypes collagenous colitis and lymphocytic colitis. The diagnosis of microscopic colitis is made by histological examination of colonic mucosal biopsy specimens. The aim of this investigation was to determine whether laboratory parameters or questions about disease history or concomitant disease could be helpful in discriminating patients with MC from those with a histologically normal colonic mucosa.

  • Cancer Risk in Collagenous Colitis
  • 2019
  • Ingår i: Journal of Clinical Medicine. - : MDPI. - 2077-0383. ; 8:11
  • Tidskriftsartikel (refereegranskat)abstract
    • Data on malignancy in patients with collagenous colitis (CC) is scarce. We aimed to determine the incidence of cancers in patients with CC. In a two-stages, observational study, data on cancers in patients diagnosed with CC during 2000-2015, were collected from two cohorts. The risk was calculated according to the age-standardized rate for the first cohort and according to the standardized incidence ratio for the second cohort. The first cohort comprised 738 patients (394 from Scotland and 344 from Sweden; mean age 71 +/- 11 and 66 +/- 13 years, respectively). The incidence rates for lung cancer (RR 3.9, p = 0.001), bladder cancer (RR 9.2, p = 0.019), and non-melanoma skin cancer (NMSC) (RR 15, p = 0.001) were increased. As the majority of NMSC cases (15/16) came from Sweden, a second Swedish cohort, comprising 1141 patients (863 women, mean age 65 years, range 20-95 years) was collected. There were 93 cancer cases (besides NMSC). The risk for colon cancer was decreased (SIR 0.23, p= 0.0087). The risk for cutaneous squamous cell carcinoma was instead markedly increased (SIR 3.27, p = 0.001).

  • Nomenclature and semantic descriptions of ulcerative and inflammatory lesions seen in Crohn’s disease in small bowel capsule endoscopy : An international Delphi consensus statement
  • Ingår i: United European Gastroenterology Journal. - : SAGE Publications. - 2050-6406. ; 8:1, s. 99-107
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: In the medical literature, the nomenclature and descriptions (ND) of small bowel (SB) ulcerative and inflammatory (U-I) lesions in capsule endoscopy (CE) are scarce and inconsistent. Inter-observer variability in interpreting these findings remains a major limitation in the assessment of the severity of mucosal lesions, which can impact negatively on clinical care, training and research on SB-CE. Objective: Focusing on SB-CE in Crohn’s disease (CD), our aim is to establish a consensus on the ND of U-I lesions. Methods: An international panel of experienced SB-CE readers was formed during the 2016 United European Gastroenterology Week meeting. A core group of five CE and inflammatory bowel disease (IBD) experts established an Internet-based, three-round Delphi consensus but did not participate in the voting process. The core group built illustrated questionnaires, including SB-CE still frames of U-I lesions from patients with documented CD. Twenty-seven other experts were asked to rate and comment on the different proposals for the ND of the most frequent SB U-I lesions. For each round, we used a 6-point rating scale (varying from ‘strongly disagree’ to ‘strongly agree’). The consensus was reached when at least 80 % of the voting members scored the statement within the ‘agree’ or ‘strongly agree’ categories. Results: A 100% participation rate was obtained for all the rounds. Consensual ND were reached for the following seven U-I lesions: aphthoid erosion, deep ulceration, superficial ulceration, stenosis, edema, hyperemia and denudation. Conclusion: Considering the most frequent SB U-I lesions seen in CE in CD, a consensual ND was reached by the international group of experts. These descriptions and names are useful not only for daily practice and medical education, but also for medical research.

  • Capsule Endoscopy Is Superior to Small-bowel Follow-through and Equivalent to Ileocolonoscopy in Suspected Crohn's Disease
  • 2014
  • Ingår i: Clinical Gastroenterology and Hepatology. - : Elsevier. - 1542-7714. ; 12:4, s. 609-615
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND & AIMS: Evaluation of the small intestine for inflammation has traditionally relied on small-bowel follow-through (SBFT), but multiple studies have demonstrated its low diagnostic accuracy. Capsule endoscopy (CE) transmits high-quality images of the small intestinal mucosa; it can be used to visualize the entire length of the small bowel and much of the mucosa. We compared the diagnostic yields of CE vs SBFT in a prospective study of patients with suspected small-bowel Crohn's disease. METHODS: Eighty patients with signs and/or symptoms of small-bowel Crohn's disease (age, 10-65 years) underwent CE, followed by SBFT and ileocolonoscopy. Readers were blinded to other test results. The primary outcome was the diagnostic yield for inflammatory lesions found with CE before ileocolonoscopy compared with SBFT and ileocolonoscopy. A secondary outcome was the incremental diagnostic yield of CE compared with ileocolonoscopy and CE compared with SBFT. RESULTS: The combination of CE and ileocolonoscopy detected 107 of 110 inflammatory lesions (97.3%), whereas the combination of SBFT and ileocolonoscopy detected only 63 lesions (57.3%) (P < .001). The diagnostic yield of CE compared with ileocolonoscopy was not different (P = .09). The diagnostic yield was higher for CE than for SBFT (P < .001). Of the 80 patients with suspected Crohn's disease, 25 (31.3%) had the diagnosis confirmed. Eleven were diagnosed by CE findings alone and 5 by ileocolonoscopy findings alone. In the remaining 9 patients, diagnostic findings were identified by at least 2 of the 3 modalities. No diagnoses were made on the basis of SBFT findings alone. CONCLUSIONS: CE was better than SBFT and equivalent to ileocolonoscopy in detecting small-bowel inflammation. Although ileocolonoscopy remains the initial diagnostic test of choice, CE is safe and can establish the diagnosis of Crohn's disease in patients when ileocolonoscopy results are negative or the terminal ileum cannot be evaluated. ClinicalTrials.gov Number: NCT00487396.

  • Self-expanding metal stents in malignant colonic obstruction: experiences from Sweden.
  • 2011
  • Ingår i: BMC Research Notes. - : BioMed Central (BMC). - 1756-0500. ; 4
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Acute surgery in the management of malignant colonic obstruction is associated with high morbidity and mortality. The use of self-expanding metal stents (SEMS) is an alternative method of decompressing colonic obstruction. SEMS may allow time to optimize the patient and to perform preoperative staging, converting acute surgery into elective. SEMS is also proposed as palliative treatment in patients with contraindications to open surgery. Aim: To review our experience of SEMS focusing on clinical outcome and complications. The method used was a review of 75 consecutive trials at SEMS on 71 patients based on stent-protocols and patient charts. FINDINGS: SEMS was used for palliation in 64 (85%) cases and as a bridge to surgery in 11 (15%) cases. The majority of obstructions, 53 (71%) cases, were located in the recto-sigmoid. Technical success was achieved in 65 (87%) cases and clinical decompression was achieved in 60 (80%) cases. Reasons for technical failure were inability to cannulate the stricture in 5 (7%) cases and suboptimal SEMS placement in 3 (4%) cases. Complications included 4 (5%) procedure-related bowel perforations of which 2 (3%) patients died in junction to post operative complications. Three cases of bleeding after SEMS occurred, none of which needed invasive treatment. Five of the SEMS occluded. Two cases of stent erosion were diagnosed at the time of surgery. Average survival after palliative SEMS treatment was 6 months. CONCLUSION: Our results correspond well to previously published data and we conclude that SEMS is a relatively safe and effective method of treating malignant colonic obstruction although the risk of SEMS-related perforations has to be taken into account.

  • Abundance of Enterobacteriaceae in the colon mucosa in diverticular disease
  • 2018
  • Ingår i: World Journal of Gastrointestinal Pathophysiology. - : Baishideng Publishing Group. - 2150-5330. ; 9:1, s. 18-27
  • Tidskriftsartikel (refereegranskat)abstract
    • AIM:To compare gut bacterial diversity and amount of Enterobacteriaceae in colonic mucosa between patients with and without diverticular disease (DD).METHODS:Patients in a stable clinical condition with planned elective colonoscopy were included. Blood samples and colon mucosa biopsies were collected at the colonoscopy. Study questionnaires including questions about gastrointestinal symptoms were completed by the patients and physicians. DNA from mucosa samples was isolated and the amount of Enterobacteriaceae was estimated using PCR assay. Terminal restriction fragment length polymorphism was applied to assess microbial diversity. Diversity was estimated by calculations of richness (number of terminal restriction fragments) and Shannon-Wiener and Simpson's indices.RESULTS:A total of 51 patients were included, 16 patients with DD [68 (62-76) years] and 35 controls [62 (40-74) years] without any diverticula. Patients with DD had significantly higher levels of Enterobacteriaceae than those without DD (P = 0.043), and there was an inverse relationship between the amount of Enterobacteriaceae and the Simpson's index (rs = -0.361, P = 0.033) and the Shannon-Wiener index (rs = -0.299, P = 0.081). The Simpson's index (P = 0.383), Shannon-Wiener index (P = 0.401) or number of restrictions fragments (P = 0.776) did not differ between DD and controls. The majority of patients experienced gastrointestinal symptoms, and 22 patients (43.1%) fulfilled the criteria for irritable bowel syndrome, with no difference between the groups (P = 0.212). Demography, socioeconomic status, lifestyle habits, inflammatory biomarkers, or symptoms were not related to the amount of Enterobacteriaceae or bacterial diversity.CONCLUSION:Patients with DD had higher amount of Enterobacteriaceae in the colon mucosa compared to patients without diverticula.

  • Dorsal agenesis of the pancreas - a rare cause of abdominal pain and insulin-dependent diabetes
  • 2012
  • Ingår i: Acta Radiologica. - : SAGE Publications. - 1600-0455. ; 53:1, s. 41309-41309
  • Tidskriftsartikel (refereegranskat)abstract
    • Dorsal agenesis of the pancreas is a rare congenital disorder. We report a case of a 65-year-old man with mild abdominal pain and insulin-dependent diabetes mellitus. Computed tomography (CT) of the abdomen showed a short pancreas with no pancreatic tissue ventral to the splenic vein. Magnetic resonance cholangiopancreatography (MRCP) visualized the absence of a dorsal duct system and confirmed the suspicion of complete agenesis of the dorsal pancreas. Endoscopic ultrasound (EUS) was also performed to rule out pancreatic malignancy.

  • Consensus guidelines for the use of bowel preparation prior to colonic diagnostic procedures: colonoscopy and small bowel video capsule endoscopy
  • 2013
  • Ingår i: Current Medical Research and Opinion. - : LibraPharm. - 1473-4877. ; 29:8, s. 931-945
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Adequate bowel preparation prior to colonic diagnostic procedures is essential to ensure adequate visualisation. Scope: This consensus aims to provide guidance as to the appropriate use of bowel preparation for a range of defined clinical circumstances. A consensus group from across Europe was convened and met to discuss appropriate bowel preparation. The use of polyethylene glycol (PEG), sodium picosulphate and sodium phosphate (NaP), together with other agents, prokinetics and simethicone, in colonoscopy and small bowel video capsule endoscopy were considered. A systematic review of the literature was carried out and additional unpublished data was obtained from the members of the consensus group where required. Recommendations were graded according to the level of evidence. Findings: PEG-based regimens are recommended first line for both procedures, since their use is supported by good efficacy and safety data. Sodium-picosulphate-based regimens are recommended second line as their cleansing efficacy appears less than PEG-based regimens. NaP is not recommended for bowel cleansing due to the potential for renal damage and other adverse events. However, the use of NaP is acceptable in patients in whom PEG or sodium picosulphate is ineffective or not tolerated. NaP should not be used in patients with chronic kidney disease, pre-existing electrolyte disturbances, congestive heart failure, cirrhosis or a history of hypertension. The timing of the dose, dietary restrictions, use in special patient groups and recording of the quality of bowel preparation are also considered for patients undergoing colonoscopy. During the development of the guidelines the European Society of Gastrointestinal Endoscopy (ESGE) issued guidance on bowel preparation for colonoscopy. The ESGE guidelines and these consensus guidelines share many recommendations; differences between the guidelines are reviewed. Conclusion: The use of bowel preparation should be tailored to the individual patient and their specific clinical circumstances.

  • Capsule retention related to small bowel capsule endoscopy : a large European single-center 10-year clinical experience
  • Ingår i: United European Gastroenterology Journal. - : SAGE Publications. - 2050-6406. ; 5:5, s. 677-686
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The most concerning complication of video capsule endoscopy (VCE) is capsule retention (CR) in the gastrointestinal (GI) tract although clinical outcome and management of patients with CR are still uncertain in a large single center material. Objectives: The aim of this retrospective study was to investigate incidence, causes, risk factors, management and clinical outcomes of CR in a large single center between 2001 and 2011. Results: 2401 consecutive small-bowel (SB) VCEs were performed. CR was detected in 25 cases (1%). CR in patients with suspected and known Crohn’s disease (CD) undergoing VCE occurred in 14/1370 (1%) including known CD 9/390 (2.3%) and suspected CD 5/980 (0.5%). CR in patients with obscure GI bleeding was observed in 11/816 (1.3%) cases. The SB was the most common site of CR with 17 cases followed by the esophagus (4 cases), colon (2 cases), and stomach (2 cases). Emergency endoscopic intervention (3 cases) and surgery (2 cases) was needed in 5 cases of CR. Elective capsule removal was performed by surgery in 6 cases and endoscopically in 8 cases. Three retained capsules dislodged after steroid treatment and another 3 cases of CR resolved without any intervention. Conclusion: This large clinical material demonstrates that CR is a rare complication with a favorable clinical outcome. Most patients with CR can be electively managed with non-surgical intervention.
