The Role of Inflammation in Crohn's Disease Recurrence after Surgical Treatment
Ontology highlight
ABSTRACT: Introduction
Postoperative recurrence after surgery for Crohn's disease (CD) is virtually inevitable, and its mechanism is poorly known. Aim
To review the numerous factors involved in CD postoperative recurrence (POR) pathogenesis, focusing on single immune system components as well as the immune system as a whole and highlighting the clinical significance in terms of preventive strategies and future perspectives. Methods
A systematic literature search on CD POR, followed by a review of the main findings. Results
The immune system plays a pivotal role in CD POR, with many different factors involved. Memory T-lymphocytes retained in mesenteric lymph nodes seem to represent the main driving force. New pathophysiology-based preventive strategies in the medical and surgical fields may help reduce POR rates. In particular, surgical strategies have already been developed and are currently under investigation. Conclusions
POR is a complex phenomenon, whose driving mechanisms are gradually being unraveled. New preventive strategies addressing these mechanisms seem promising.

Project description:Postoperative recurrence after ileocaecal resection for fibrostenotic terminal ileal Crohn's disease is a significant issue for patients as it can result in symptom recurrence and requirement for further surgery. There are very few modifiable factors, aside from smoking cessation, that can reduce the risk of postoperative recurrence. Until relatively recently, the surgical technique used for resection and anastomosis had little or no impact on postoperative recurrence rates. Novel surgical techniques such as the Kono-S anastomosis and extended mesenteric excision have shown promise as ways to reduce postoperative recurrence rates. This manuscript will review and discuss the evidence regarding a range of surgical techniques and their potential role in reducing disease recurrence. Some of the techniques have been shown to be associated with significant benefits for patients and have already been integrated into the routine clinical practice of some surgeons, while other techniques remain under investigation. Current techniques such as resection of the mesentery close to the intestine and stapled side to side anastomosis are being challenged. It is looking more likely that surgeons will have a major role to play when it comes to reducing recurrence rates for patients undergoing ileocaecal resection for Crohn's disease.

Project description:More than 80% of patients with Crohn's disease (CD) will require surgical intervention during their lifetime, with high rates of anastomotic recurrence and stenosis necessitating repeat surgery. Current data show that pharmacotherapy has not significantly improved the natural history of postoperative clinical and surgical recurrence of CD. In 2003, antimesenteric hand-sewn functional end-to-end (Kono-S) anastomosis was first performed in Japan. This technique has yielded very desirable outcomes in terms of reducing the incidence of anastomotic surgical recurrence. The most recent follow-up of these patients showed that very few had developed surgical recurrence. This new approach is superior to stapled functional end-to-end anastomosis because the stumps are sutured together to create a stabilizing structure (a "supporting column"), serving as a supportive backbone of the anastomosis to help prevent distortion of the anastomotic lumen due to disease recurrence and subsequent clinical symptoms. This technique requires careful mesenteric excision for optimal preservation of the blood supply and innervation. It also results in a very wide anastomotic lumen on the antimesenteric side. The Kono-S technique has shown efficacy in preventing surgical recurrence and the potential to become the new standard of care for intestinal CD.

Project description:AIM:The risk factors that predict surgical recurrence in Crohn's disease (CD) remain controversial. Postoperative anti-tumour necrosis factor (anti-TNF) therapy might lower recurrence rates whilst the presence of mesenteric granulomas has been postulated to increase the risk. We hypothesized that mesenteric granulomas indicate disease severity and might predict the risk of surgical recurrence, irrespective of immunosuppressive therapy. METHOD:We performed a retrospective review of all consecutive patients undergoing operations for CD between January 2000 and December 2014 at a single tertiary referral centre and assessed the perioperative factors and histological findings at the time of surgery. Surgical recurrence rates and the immunosuppressive regimen were assessed through retrospective chart review and telephone interviews. RESULTS:A total of 274 patients were eligible for analysis. Median follow-up was 8.54 (5.48-14.42) years. A total of 63 patients (23.0%) underwent surgery for recurrent CD after a median of 4.75 (2.10-7.96) years. In final histology, 35 (12.8%) patients had mesenteric granulomas. TNF inhibitors were administered postoperatively in 104 (38.0%) and thiopurines in 137 (50.0%) patients. In univariate analysis, only the presence of mesenteric granulomas [hazard ratio (HR) 1.95; 95% CI 1.05-3.62; P = 0.035] significantly increased the risk for recurrent surgery while postoperative anti-TNF (HR 0.85; 95% CI 0.49-1.50; P = 0.581) or thiopurine therapy (HR 1.03; 95% CI 0.61-1.73; P = 0.916) did not. In multivariate analysis, only the presence of mesenteric granulomas significantly influenced the risk of surgical recurrence (HR 1.94, 95% CI 1.04-3.60; P = 0.037). CONCLUSION:Intestinal and mesenteric granulomas should be differentiated in pathology reports, because mesenteric, but not intestinal, granulomas may be associated with an increased risk of surgical recurrence.

Project description:AIM:To examine the relationship between elevated granulocyte-macrophage colony-stimulating factor (GM-CSF) auto-antibodies (Ab) level and time to surgical recurrence after initial surgery for Crohn's disease (CD). METHODS:We reviewed 412 charts from a clinical database at tertiary academic hospital. Patients included in the study had ileal or ileocolonic CD and surgical resection of small bowel or ileocecal region for management of disease. Serum samples were analyzed for serological assays including GM-CSF cytokine, GM-CSF Ab, ASCA IgG and IgA, and genetic markers including SNPs rs2066843, rs2066844, rs2066845, rs2076756 and rs2066847 in NOD2, rs2241880 in ATG16L1, and rs13361189 in IRGM. Cox proportional-hazards models were used to assess the predictors of surgical recurrence. RESULTS:Ninety six percent of patients underwent initial ileocecal resection (ICR) or ileal resection (IR) and subsequently 40% of patients required a second ICR/IR for CD. GM-CSF Ab level was elevated at a median of 3.81 mcg/mL. Factors predicting faster time to a second surgery included elevated GM-CSF Ab [hazard ratio (HR) 3.52, 95%CI: 1.45-8.53, P = 0.005] and elevated GM-CSF cytokine (HR = 2.48, 95%CI: 1.31-4.70, P = 0.005). Factors predicting longer duration between first and second surgery included use of Immunomodulators (HR = 0.49, 95%CI: 0.31-0.77, P = 0.002), the interaction effect of low GM-CSF Ab levels and smoking (HR = 0.60, 95%CI: 0.45-0.81, P = 0.001) and the interaction effect of low GM-CSF cytokine levels and ATG16L1 (HR = 0.65, 95%CI: 0.49-0.88, P = 0.006). CONCLUSION:GM-CSF bioavailability plays a critical role in maintaining intestinal homeostasis. Decreased bioavailability coupled with the genetic risk markers and/or smoking results in aggressive CD behavior.

Project description:AimThe different surgical options for patients with colonic Crohn's disease (CD) include segmental colectomy, subtotal colectomy or proctocolectomy with end ileostomy. We present a national, multicentre study, promoted by the Italian Society of Colorectal Surgery with the aim to collect benchmark data and national variations on multidisciplinary management and postoperative outcomes of patients undergoing surgery for colonic CD.MethodsAll adult patients having elective surgery for colonic CD from June 2018 to May 2019 were eligible for participation in this retrospective study. The primary outcome measure was postoperative morbidity within 30 days of surgery.ResultsOne hundred twenty-two patients were included: 55 subtotal colectomy, 30 segmental colectomy, 25 proctectomy and 12 proctocolectomy. Eighty-six patients (70.4%) were discussed at the inflammatory bowel disease (IBD) multidisciplinary team meeting (MDT) prior to surgery. This ranged from 76.6% for segmental colectomy to 60% for subtotal colectomy, 66.6% for proctocolectomy and 48% for proctectomy. The proportion of patients counselled by a stoma nurse preoperatively was 50%. Laparoscopy was associated with reduced postoperative morbidity (p = 0.017) and shorter length of hospital stay (p < 0.001), whilst pre-operative anti-TNF was associated with Dindo-Clavien ≥ 3 complications (p = 0.023) and longer in-hospital stay (p = 0.007). The main procedure performed (segmental colectomy, subtotal colectomy, proctocolectomy or proctectomy) was not associated with postoperative morbidity (p = 0.626).ConclusionsSurgery for colonic CD has a high rate of postoperative complications. Almost a third of the patients were not preoperatively discussed at the IBD MDT, whilst the use of minimally invasive surgery for surgical treatment of colonic CD ranges from 40 to 66%.

Project description:Background and aimsInclusion of the mesentery during resection for colorectal cancer is associated with improved outcomes but has yet to be evaluated in Crohn's disease. This study aimed to determine the rate of surgical recurrence after inclusion of mesentery during ileocolic resection for Crohn's disease.MethodsSurgical recurrence rates were compared between two cohorts. Cohort A [n = 30] underwent conventional ileocolic resection where the mesentery was divided flush with the intestine. Cohort B [n = 34] underwent resection which included excision of the mesentery. The relationship between mesenteric disease severity and surgical recurrence was determined in a separate cohort [n = 94]. A mesenteric disease activity index was developed to quantify disease severity. This was correlated with the Crohn's disease activity index and the fibrocyte percentage in circulating white cells.ResultsCumulative reoperation rates were 40% and 2.9% in cohorts A and B [P = 0.003], respectively. Surgical technique was an independent determinant of outcome [P = 0.007]. Length of resected intestine was shorter in cohort B, whilst lymph node yield was higher [12.25 ± 13 versus 2.4 ± 2.9, P = 0.002]. Advanced mesenteric disease predicted increased surgical recurrence [Hazard Ratio 4.7, 95% Confidence Interval: 1.71-13.01, P = 0.003]. The mesenteric disease activity index correlated with the mucosal disease activity index [r = 0.76, p < 0.0001] and the Crohn's disease activity index [r = 0.70, p < 0.0001]. The mesenteric disease activity index was significantly worse in smokers and correlated with increases in circulating fibrocytes.ConclusionsInclusion of mesentery in ileocolic resection for Crohn's disease is associated with reduced recurrence requiring reoperation.

Project description:Background and aimsCrohn's disease [CD] recurrence following ileocolic resection [ICR] is common. We sought to identify blood-based biomarkers associated with CD recurrence.MethodsCD patients undergoing ICR were recruited across six centres. Serum samples were obtained at post-operative colonoscopy. A multiplex immunoassay was used to analyse 92 inflammation-related proteins [Olink Proteomics]. Bayesian analysis was used to identify proteins associated with increasing Rutgeerts score. Identified proteins were used in receiver operating characteristic [ROC] analysis to examine the ability to identify CD recurrence [Rutgeerts score ≥i2]. Existing single cell data were interrogated to further elucidate the role of the identified proteins.ResultsData from 276 colonoscopies in 213 patients were available. Median time from surgery to first and second colonoscopy was 7 (interquartile range [IQR] 6-9) and 19 [IQR 16-23] months, respectively. Disease recurrence was evident at 60 [30%] first and 36 [49%] second colonoscopies. Of 14 proteins significantly associated with Rutgeerts score, the strongest signal was seen for CXCL9 and MMP1. Among patients on anti-tumour necrosis factor drugs, CXCL9 and CXCL11 were most strongly associated with Rutgeerts score. Both are CXCR3 ligands. Incorporation of identified proteins into ROC analysis improved the ability to identify disease recurrence as compared to C-reactive protein alone: area under the curve [AUC] 0.75 (95% confidence interval [CI]: 0.66-0.82] vs 0.64 [95% CI 0.56-0.72], p = 0.012. Single cell transcriptomic data provide evidence that innate immune cells are the primary source of the identified proteins.ConclusionsCXCR3 ligands are associated with CD recurrence following ICR. Incorporation of novel blood-based candidate biomarkers may aid in identification of CD recurrence.

Project description:BackgroundAntimesenteric cutback end-to-end isoperistaltic anastomosis (Sasaki-Watanabe anastomosis; Sasaki-W anastomosis), which was developed in our department, is a novel hand-sewn anastomotic technique for Crohn's disease intended to prevent anastomotic stenosis and preserve the peripheral circulation.AimThe aim of the present study is to present the surgical technique of Sasaki-W anastomosis and to assess the safety and the early results of the surgical anastomotic recurrence of Sasaki-W anastomosis.Patients and methodsThe present study was a single-center retrospective cohort study. As an early-period group, 13 patients with Crohn's disease, who were mainly selected from cases considered to be at high risk of recurrence, underwent 15 Sasaki-W anastomoses from August 2009 to January 2012. As a late-period group, 36 patients with Crohn's disease, who were selected regardless of risk factors, underwent 37 Sasaki-W anastomoses from September 2016 to March 2020. The medical data including patient characteristics, surgical records, postoperative details, and surgical recurrences were assessed.ResultsThere were no intraoperative complications. With a median follow-up of 107 mo, surgical recurrence occurred in one patient at 106 mo after surgery in the early-period group. The cumulative surgical recurrence-free rate in the early-period group was 100% at 5 y and 86% at 10 y after surgery. No patients required reoperation in the late-period group.ConclusionSasaki-W anastomosis is safe and feasible. Although long-term study is needed, this anastomotic technique can be a reasonable operative option for Crohn's disease.

Project description:IntroductionMicroRNAs (miRNAs) are important epigenetic regulators in Crohn's disease (CD); however, their contribution to postoperative recurrence (POR) is still unknown. We aimed to characterize the potential role of miRNAs in predicting POR in patients with CD and to identify their pathogenic implications.MethodsOf 67 consecutively operated patients with CD, we included 44 with pure ileal CD. Peripheral blood samples were taken before surgery and during follow-up. The patients were classified according to the presence or absence of POR assessed by ileocolonoscopy or magnetic resonance imaging enterography. The miRNAs were profiled by reverse transcription polymerase chain reaction before surgery and during morphological POR or, for those who remained in remission, 1 year after surgery. R software and mirWalk were used.ResultsFive human miRNAs (miR-191-5p, miR-15b-5p, miR-106b-5p, miR-451a, and miR-93-5p) were selected for discriminating between the 2 patient groups at presurgery (PS), with an area under the curve of 0.88 (95% confidence interval [0.79, 0.98]). Another 5 (miR-15b-5p, miR-451a, miR-93-5p, miR-423-5p, and miR-125b-5p) were selected for 1 year, with an area under the curve of 0.96 (95% confidence interval [0.91, 1.0]). We also created nomograms for POR risk estimation. CCND2 and BCL9L genes were related to PS miRNA profiles; SENP5 and AKT3 genes were related to PS and 1 year; and SUV39H1 and MAPK3K10 were related to 1 year.DiscussionDifferent plasma miRNA signatures identify patients at high POR risk, which could help optimize patient outcomes. We developed nomograms to facilitate the clinical use of these results. The identified miRNAs participate in apoptosis, autophagy, proinflammatory immunological T-cell clusters, and reactive oxygen species metabolism.

Project description:PurposeAdventitial cystic disease (ACD) is a rare condition that causes intermittent claudication and non-atherosclerotic disease without cardiovascular risk factors. The etiology and optimal treatment of ACD remain controversial. The purpose of this study was to analyze surgical treatment results for ACD and to elucidate optimal treatment options.Materials and methodsWe retrospectively reviewed 30 patients with ACD who underwent surgery from 2006 to 2018. Twenty-two patients had arterial ACD, six had venous ACD, and two had combined venous and arterial ACD. We reviewed demographic and clinical characteristics, treatment details, and procedure outcomes.ResultsRecurrence occurred in 6 cases either after cyst excision alone (4/17) or patch angioplasty (2/2). There was no recurrence after vessel excision with interposition grafting (0/7). Therefore, vessel excision was a statistically significant factor in recurrence prevention (P=0.026). Among the six recurrences, joint connections of the cystic lesions were found in four of the six (66.7%).ConclusionAs a curative surgery for ACD, vessel excision with interposition grafting is a better strategy to prevent recurrence than simple cyst excision alone.
