RESUMEN
BACKGROUND: Retrospective research suggests that excision of the affected mesentery can improve outcomes after an ileocoecal resection in Crohn's disease. However, prospective data from randomised controlled trials are scarce. We aimed to compare rates of postoperative recurrence in patients with Crohn's disease who underwent extended mesenteric resection. METHODS: This international, randomised controlled trial was done in six hospitals and tertiary care centres in the Netherlands and Italy. Eligible patients were aged 16 years or older and had Crohn's disease that was previously confirmed by endoscopy in the terminal ileum or ileocolic region (L1 or L3 disease), with an imaging update in the past 3 months (ultrasound, MRI, or CT enterography). Eligible patients were scheduled to undergo primary ileocolic resection with ileocolic anastomosis. Enrolled patients were assigned by use of simple random allocation (1:1) to either extended mesenteric resection (intervention) or conventional mesenteric sparing resection (control). The primary endpoint was endoscopic recurrence 6 months after surgery. Analyses were done in all patients with primary endpoint data, excluding those who had no anastomosis, a postoperative diagnosis other than Crohn's disease, or withdrew consent. This trial was registered with ClinicalTrials.gov, NCT04538638. FINDINGS: Between Feb 19, 2020, and April 24, 2023, we assessed 217 patients for eligibility. 78 patients were excluded due to failure to meet the inclusion criteria or refusal to participate. 139 patients were enrolled and randomly assigned to either extended mesenteric resection (n=71) or mesenteric sparing resection (n=68). All 139 patients underwent surgery. Six patients were excluded after random assignment due to withdrawal of consent (n=2), postoperative diagnosis other than Crohn's disease (n=2) and no anastomosis performed (in case of a stoma; n=2). Two patients were lost to follow-up, and two more patients deviated from the protocol by undergoing investigations other than endoscopy 6 months after. 133 patients were included in the baseline analysis (67 in the extended resection group and 66 in the sparing resection group) of whom 57 (43%) were male. Baseline characteristics were similar between the groups, and median patient age was 36 years (IQR 25-54). 131 patients were analysed for the primary outcome. There was no difference between groups in the rate of endoscopic recurrence at 6 months after surgery (28 [42%] of 66 patients in the extended mesenteric resection group vs 28 [43%] of 65 patients in the mesenteric sparing resection group, relative risk 0·985, 95% CI 0·663-1·464; p=1·0). Five (8%) of 66 patients in the extended mesenteric resection group had anastomotic leakage within the 30 days after surgery, as did one (2%) of 65 in the mesenteric sparing group. Postoperative complications of Clavien-Dindo grade IIIa or higher were reported in seven (11%) patients in the mesenteric resection group and five (8%) in the mesenteric sparing group. INTERPRETATION: Extended mesenteric resection was not superior to conventional resection with regard to endoscopic Crohn's disease recurrence. These data support the guideline-recommended mesenteric sparing approach. FUNDING: Topconsortia voor Kennis en Innovatie-Topsector Life Sciences & Health.

Objective: Guidelines advise to perform endoscopic surveillance following ileocolic resection (ICR) in Crohn disease (CD) for timely diagnosis of recurrence. This study aims to assess the variation in endoscopic recurrence (ER) rates in patients after ICR for CD using the most commonly used classification systems, the Rutgeerts score (RS) and modified Rutgeerts score (mRS) classifications. Methods: A systematic literature search using MEDLINE, Embase, and the Cochrane Library was performed. Randomized controlled trials and cohort studies describing ER < 12 months after an ICR for CD were included. Animal studies, reviews, case reports (<30 included patients), pediatric studies, and letters were excluded. The Newcastle-Ottawa Quality Assessment Scale and Cochrane Collaboration's tool were used to assess risk of bias. Main outcome was the range of ER rates within 12 months postoperatively, defined as RS ≥ i2 and/or mRS ≥ i2b. A proportional meta-analysis was performed. The final search was performed on January 4, 2022. The study was registered at PROSPERO, CRD42022363208. Results: Seventy-six studies comprising 7751 patients were included. The weighted mean of ER rates in all included studies was 44.0% (95% confidence interval, 43.56-44.43). The overall range was 5.0% to 93.0% [interquartile range (IQR), 29.2-59.0]. The weighted means for RS and mRS were 44.0% and 41.1%, respectively. The variation in ER rates for RS and mRS were 5.0% to 93.0% (IQR, 29.0-59.5) and 19.8% to 62.9% (IQR, 37.3-46.5), respectively. Within studies reporting both RS and mRS, the weighted means for ER were 61.3% and 40.6%, respectively. Conclusions: This study demonstrates a major variation in ER rates after ICR for CD, suggesting a high likelihood of inadequate diagnosis of disease recurrence, with potentially impact on quality of life and health care consumption. Therefore, there is an important need to improve endoscopic scoring of recurrent disease.
RESUMEN
BACKGROUND: The most common intestinal operation in Crohn's disease (CD) is an ileocolic resection. Despite optimal surgical and medical management, recurrent disease after surgery is common. Different types of anastomoses with respect to configuration and construction can be made after resection for example, handsewn (end-to-end and Kono-S) and stapled (side-to-side). The various types of anastomoses might affect endoscopic recurrence and its assessment, the functional outcome, and costs. The objective of the present study is to compare the three types of anastomoses with respect to endoscopic recurrence at 6 months, gastrointestinal function, and health care consumption. METHODS: This is a randomized controlled multicentre superiority trial, allocating patients either to side-to-side stapled anastomosis as advised in current guidelines or a handsewn anastomoses (an end-to-end or Kono-S). It is hypothesized that handsewn anastomoses do better than stapled, and end-to-end perform better than the saccular Kono-S. Two international studies with a similar setup will be conducted mainly in the Netherlands (End2End) and Italy (HAND2END). Patients diagnosed with CD, aged over 16 years in the Netherlands and 18 years in Italy requiring (re)resection of the (neo)terminal ileum are eligible. The first part of the study compares the two handsewn anastomoses with the stapled anastomosis. To detect a clinically relevant difference of 25% in endoscopic recurrence, a total of 165 patients will be needed in the Netherlands and 189 patients in Italy. Primary outcome is postoperative endoscopic recurrence (defined as Rutgeerts score ≥ i2b) at 6 months. Secondary outcomes are postoperative morbidity, gastrointestinal function, quality of life (QoL) and costs. DISCUSSION: The research question addresses a knowledge gap within the general practice elucidating which type of anastomosis is superior in terms of endoscopic and clinical recurrence, functionality, QoL and health care consumption. The results of the proposed study might change current practice in contrast to what is advised by the guidelines.

BACKGROUND AND AIMS: An appendectomy for appendiceal inflammation has been suggested to ameliorate the clinical course of patients with ulcerative colitis (UC). In contrast, for Crohn's disease (CD) an inverse association has been suggested with a higher incidence of CD and worse prognosis after appendectomy. The aim of this study was to analyse the clinical relevance of an inflamed appendix in CD patients undergoing ileocoecal resection (ICR). METHODS: All consecutive patients undergoing primary ICR between 2007 and 2018 were considered for inclusion. Microscopic data of available appendiceal resection specimens (n=99) were revised by a dedicated IBD-pathologist and scored as inflamed or not inflamed. Eighteen patients had a previous appendectomy. Pathological findings were correlated with disease characteristics and recurrence rates (clinical, endoscopic and intervention-related). RESULTS: In total, 117 patients were included: 77 (65.8%) females with a median age of 30 years [IQR 24 - 43] with a median follow up of 102 months [IQR 76-114]. Of patients without previous appendectomy (n=99), 39% had an inflamed appendix. No significant differences in disease characteristics (e.g. disease location, behaviour, time to surgery) or prognosis could be demonstrated between the two groups. In contrast, previous appendectomy (n=18) was associated with penetrating disease and numerically shorter disease duration at the time of resection. Furthermore, a trend was seen towards a stronger association with postoperative recurrence. CONCLUSION: The current study could not confirm a different prognosis for CD patients with and without an inflamed appendix. In contrast, in patients with a previous appendectomy a trend was seen towards increased postoperative recurrence, which might be related to the higher incidence of penetrating disease.
RESUMEN
BACKGROUND AND AIMS: Adequate endoscopic scoring in Crohn's disease [CD] is crucial, as it dictates the need for initiating postoperative medical therapy and is utilized as an outcome parameter in clinical trials. Here we aimed to observe anastomotic wound healing in relation to endoscopic scoring of both inverted and everted stapled lines in side-to-side anastomoses. METHODS: Two prospective patient cohorts were included: ileocolic resection [ICR] for CD, and right-sided colon resection for colorectal cancer [CRC]. Videos taken during colonoscopy 6 months postoperatively were evaluated. The Simplified Endoscopic Activity Score for Crohn's Disease and modified Rutgeerts score were determined. The primary outcome was the presence of ulcerations in CD patients on both the inverted and the everted stapled lines. Secondary outcomes were the presence of anastomotic ulcerations in CRC patients and the number of cases having ulcerations exclusively at the inverted stapled line. RESULTS: Of the 82 patients included in the CD cohort, ulcerations were present in 63/82 [76.8%] at the inverted- vs 1/71 [1.4%] at the everted stapled line. Likewise in the CRC cohort, ulcerations were present in 4/6 [67.7%] at the inverted vs 0/6 [0%] at the everted stapled line. In total, 27% of the 63 patients in the CD cohort had ulcerations exclusively on the inverted stapled line. CONCLUSION: Inverted stapled lines heal with ulcerations, whereas everted stapled lines heal without any ulcerations, in both CD and non-CD patients. The abnormalities at the inverted stapled line might interfere with endoscopic scoring of recurrence, with potentially an impact on patients' quality of life and on healthcare costs if postoperative treatment is initiated incorrectly.

OBJECTIVES: Oncoplastic breast conserving surgery (BCS) frequently induces asymmetry. Contralateral reduction mammoplasty (CRM) is therefore part of the oncoplastic approach. Our patients frequently declined CRM when offered as a second-stage procedure after the completion of adjuvant treatments. This qualitative interview study was conducted to explore the factors involved in patient decision-making about CRM. MATERIALS AND METHODS: From the prospective hospital database of patients who underwent oncoplastic BCS for stage I-III breast cancer since 2010, 25 patients were sampled using stratified purposeful sampling on age, preoperative cup size, and time elapsed since the completion of adjuvant treatments. Nine had undergone CRM. Individual face-to-face semi-structured interviews were conducted at the hospital or at patients' homes. The interviews were audio-recorded, transcribed verbatim, and analyzed thematically. Data saturation occurred after analysis of the fifth interview, although variability within the data kept expanding until the last interview was coded. RESULTS: Eighteen patients reported postoperative breast asymmetry. Breast symmetry was important to our patients and information provision about CRM had been adequate. The following factors motivated patients to choose CRM: perceivable asymmetry, satisfaction with the outcome of oncoplastic BCS, and the wish for breast reduction before cancer diagnosis. Patients weighed these considerations against their concerns about surgery risks and recovery time. Reluctance to have nonessential surgery to the unaffected breast was an important reason to decide against CRM. CONCLUSION: Breast asymmetry is often tolerated after oncoplastic BCS because of concerns about surgery risks and recovery time and reluctance to have nonessential surgery to the healthy breast.
