    Abdominal abscess in Crohn's disease: multidisciplinary management

    No full text
    Crohn's disease (CD) is characterized by full-thickness inflammation of the bowel. For this reason, perforating complications such as intra-abdominal abscesses or fistulas are common. A concomitant intra-abdominal abscess with active CD of the small bowel is a challenging dilemma for gastroenterologists and surgeons. Since there is active and severe disease, this should be treated with immunosuppressive drugs. However, in the presence of an intra-abdominal abscess, immunosuppression can be dangerous. There are several treatment options for intra-abdominal abscesses in CD. Nowadays, the first-line treatment is antibiotic therapy with or without percutaneous drainage. Historically, patients were treated with surgical drainage. With the development of percutaneous drainage, treatment shifted to a more nonsurgical approach. Success rates for percutaneous drainage in the literature vary from 74 to 100%, and it is considered to be a relatively safe procedure. It has been reported that surgery can be avoided after successful percutaneous drainage in a variable number of patients (14-85%). If sepsis is controlled, CD medication should be started to prevent recurrence. It is important to monitor the effect upon CD lesions to avoid further perforating complications. Finally, an undrainable or small abscess can be treated with antibiotics alone, although high recurrence rates have been described with this approach. Patients with a concomitant stenosis, an enterocutaneous fistula or refractory active disease are likely to require surgery. Percutaneous drainage in combination with delayed surgery is useful to improve the patient's condition prior to surgery and is associated with less morbidity, a lower stoma rate and more limited resection. In conclusion, when feasible, percutaneous drainage and antibiotics should be the treatment of choice in patients with an intra-abdominal abscess in CD. If surgery is inevitable, this must be delayed to reduce postoperative septic complications and high stoma rate

    The AMSTAR-2 critical appraisal tool and editorial decision-making for systematic reviews: Retrospective, bibliometric study

    No full text
    AMSTAR-2 is a critical appraisal instrument for systematic reviews and may have a role in editorial processes. This study explored whether associations exist between AMSTAR-2 assessments and editorial decisions. A retrospective, cross-sectional study of manuscripts submitted to a single journal between 2015 and 2017 was undertaken. All submissions that reported an eligible systematic review were assessed using AMSTAR-2 by two assessors. Inter-rater agreement (IRR) was calculated for all AMSTAR-2 items. Associations between AMSTAR-2 assessments and the editorial decision, final publication status in any journal, and measures of impact were explored. One hundred and twenty-two manuscripts were included. Across all AMSTAR-2 items, the IRR varied from 0.03 (slight agreement) to 0.82 (substantial agreement). All submissions contained at least two critical methodological weaknesses. There was no difference in the number of weaknesses (median: 4; IQR: 3–5 vs. median: 4; IQR: 3.5–4.5; p = 0.482) between accepted and rejected submissions. Neither was there a difference between rejected submissions published elsewhere and those which remained unpublished (median: 4; IQR: 3.5–4.5 vs. median: 4; IQR: 4.5–5; p = 0.103). The number of weaknesses was not associated with academic impact. There was no association with AMSTAR-2 assessments and editorial outcomes. Further work is required to explore whether the instrument can be prospectively operationalized for use during editorial processes

    No full text
    Patients with perianal fistulas are frequently treated by a knotted seton which is well-known for causing complaints. We aimed to assess the feasibility of the knotless SuperSeton and advantages with respect to perianal disease activity. In a prospective cohort study, we included all consecutive adult patients with a knotted seton in situ or a perianal fistula requiring new seton drainage. Primary endpoint was seton feasibility (maintenance of the connection for minimally three months). Secondary endpoints included improvement of the Perianal Disease Activity Index (PDAI), complications and re-interventions within three months of follow-up. PDAI scores of patients with a knotted seton were crossover compared to PDAI scores after knotless seton replacement. Sixty patients (42% male, mean age 42 (SD 13.15), 41 with Crohn’s disease) were included between August 2016 and April 2018. Of 79 knotless setons, 69 (87.3%) stayed connected for ≥ 3 months. Overall, the knotless seton significantly decreased discharge (P = 0.001), pain (P &lt; 0.001) and induration (P &lt; 0.001) measured by the PDAI when compared to baseline. In patients with a knotted seton, replacement by the knotless seton significantly decreased discharge (P = 0.005) and pain (P &lt; 0.001) measured by the PDAI. Furthermore, 71% of patients reported fewer cleaning problems compared to the knotted seton. Ten patients developed a perianal abscess, and five patients required a re-intervention. This study supports the feasibility of the knotless seton with promising short-term results. The knotless seton might be preferred over the knotted seton in terms of perianal disease activity.</p

    BACKGROUND AND AIMS: Rectal resection in inflammatory bowel disease [IBD] is frequently complicated by disturbed perineal wound healing. Close rectal dissection, where the mesorectum remains in situ, is hypothesized to reduce complications by minimizing dead space, compared to total mesorectal excision. The aim of this study was to analyse post-operative outcomes of both techniques. In addition, immune activity in mesorectal tissue was assessed. METHODS: Perineal complications and healing were retrospectively assessed in a series of 74 IBD patients undergoing proctectomy using close rectal dissection or total mesorectal excision. The mesorectums of 15 patients were analysed by fluorescence-activated cell sorting, immunofluorescence and in situ hybridization. Based on the clinical and in vitro findings, a novel surgical approach for Crohn's disease patients with disturbed perineal healing after proctectomy was developed. RESULTS: In Crohn's disease, perineal complications were more frequent after close rectal dissection than after total mesorectal excision [59.5% vs 17.6%; p = 0.007] with lower healing rates [51.4% vs 88.2%; p = 0.014]. No differences were observed in ulcerative colitis. The mesorectal tissue in Crohn's disease contained enhanced numbers of tumour necrosis factor α-producing CD14+ macrophages, with less expression of the wound-healing marker CD206. Based on these findings, mesorectal excision with omentoplasty was performed in eight patients with perineal complications after close rectal dissection, resulting in complete perineal wound closure in six. Pro-inflammatory characteristics remained present in the mesorectum after close rectal dissection in these patients. CONCLUSIONS: In Crohn's disease, close rectal dissection resulted in more perineal complications, associated with a pro-inflammatory immune status of the mesorectal tissue. Excision of this pro-inflammatory mesenteric tissue resulted in improved perineal healing rates

    Laparoscopic ileocaecal resection versus infliximab for terminal ileitis in Crohn's disease:retrospective long-term follow-up of the LIR!C trial

    No full text
    BACKGROUND: The LIR!C trial showed that laparoscopic ileocaecal resection is a cost-effective treatment that has similar quality-of-life outcomes to treatment with infliximab, an anti-tumour necrosis factor (TNF) drug. We aimed to compare long-term outcomes of both interventions and identify baseline factors associated with the duration of treatment effect in each group. METHODS: In this retrospective follow-up study, we collected data from patients who participated in the LIR!C trial, a multicentre randomised controlled trial that compared quality of life after surgical resection versus infliximab in adult patients with non-stricturing and immunomodulator-refractory ileocaecal Crohn's disease. From Jan 1 to May 1, 2018, we collected follow-up data from the time from enrolment in the LIR!C trial until the last visit at either the gastrointestinal surgeon or gastroenterologist. In this study, outcomes of interest were need for surgery or repeat surgery or anti-TNF therapy, duration of treatment effect, and identification of factors associated with the duration of treatment effect. Duration of treatment effect was defined as the time without need for additional Crohn's disease-related treatment (corticosteroids, immunomodulators, biologics, or surgery). FINDINGS: We collected long-term follow-up data for 134 (94%) of 143 patients included in the LIR!C trial, of whom 69 were in the resection group and 65 were in the infliximab group. Median follow-up was 63·5 months (IQR 39·0-94·5). In the resection group, 18 (26%) of 69 patients started anti-TNF therapy and none required a second resection. 29 (42%) patients in the resection group did not require additional Crohn's disease-related medication, although 14 (48%) of these patients were given prophylactic immunomodulator therapy. In the infliximab group, 31 (48%) of 65 patients had a Crohn's disease-related resection, and the remaining 34 patients maintained, switched, or escalated their anti-TNF therapy. Duration of treatment effect was similar in both groups, with a median time without additional Crohn's disease-related treatment of 33·0 months (95% CI 15·1-50·9) in the resection group and 34·0 months (0·0-69·3) in the infliximab group (log-rank p=0·52). In both groups, therapy with an immunomodulator, in addition to the allocated treatment, was associated with duration of treatment effect (hazard ratio for resection group 0·34 [95% CI 0·16-0·69] and for infliximab group 0·49 [0·26-0·93]). INTERPRETATION: These findings further support laparoscopic ileocaecal resection as a treatment option in patients with Crohn's disease with limited (affected segment ≤40 cm) and predominantly inflammatory terminal ileitis for whom conventional treatment is not successful. FUNDING: None

    Background & Aims: Data regarding health-related quality of life (HRQoL) in primary sclerosing cholangitis (PSC) are sparse and have only been studied cross-sectionally in a disease which runs a fluctuating and unpredictable course. We aim to describe HRQoL longitudinally by using repeated measurements in a population-based cohort. Methods: Every 3 months from May 2017 up to August 2020, patients received digital questionnaires at home. These included the EQ-5D, 5-D Itch, patient-based SCCAI and patient-based HBI. The SF-36, measuring HRQoL over eight dimensions as well as a physical component summary (PCS) and mental component summary (MCS) score, was sent annually. Data were compared with Dutch reference data and a matched IBD disease control from the population-based POBASIC cohort. Mixed-effects modelling was performed to identify factors associated with HRQoL. Results: Three hundred twenty-eight patients completed 2576 questionnaires. A significant reduction of small clinical relevance in several mean HRQoL scores was found compared with the Dutch reference population: 46.4 versus 48.0, p =.018 for PCS and 47.5 versus 50.5, p =.004 for MCS scores. HRQoL outcomes were significantly negatively associated with coexisting active IBD (PCS −12.2, p <.001 and MCS −12.0, p <.001), which was not the case in case of quiescent IBD. Decreasing HRQoL scores were also negatively associated with increasing age (PCS −0.1 per 10 years, p =.002), female sex (PCS -2.8, p <.001), diagnosis of AIH overlap (PCS -3.7, p =.059), end-stage liver disease (PCS -3.7, p =.015) and presence of itch (PCS -9.2, p <.001 and MCS −3.1, p =.078). The odds of reporting a clinically relevant reduction in EQ-5D scores showed seasonal variation, being lowest in summer (OR = 0.48 relative to spring, p =.037). In patients with liver transplant, HRQoL outcomes were comparable to the Dutch general population. Conclusions: PSC patients report impaired HRQoL of small clinical relevance compared with the general population. After liver transplantation, HRQoL scores are at comparable levels to the general population. HRQoL scores are associated with potentially modifiable factors such as itch and IBD activity
