Abstract
Postoperative disease recurrence in Crohn's disease represents a relevant issue despite recent advancements in surgical and medical therapies. Additional criteria are necessary to improve the identification of patients at risk and to enable selective therapeutic approaches. The role of resection margins on disease recurrence remains unclear and general recommendations are lacking. A single-center retrospective analysis was performed including all patients who received ileocecal resection due to Crohn's disease. Resection margins were analyzed by two independent pathologists and defined by histopathological criteria based on previous consensus reports. 158 patients were included for analysis with a median follow up of 35 months. While postoperative morbidity was not affected, positive resection margins resulted in significantly increased rates of severe endoscopic recurrence at 6 months (2.0% versus 15.6%, p = 0.02) and overall (4.2% versus 19.6%, p = 0.001), which resulted in significantly increased numbers of surgical recurrence (0% versus 4.5%, p = 0.04). Additionally, positive margins were identified as independent risk factor for severe endoscopic disease recurrence in a multivariate analysis. Based on that, positive margins represent an independent risk factor for postoperative endoscopic and surgical disease recurrence. Prospective studies are required to determine whether extended resection or postoperative medical prophylaxis is beneficial for patients with positive resection margins.

Abstract
INTRODUCTION There is debate over the impact of residual microscopic disease after ileocecal resection in Crohn's disease (CD) to predict recurrence. We conducted a meta-analysis to evaluate the impact of positive histological margins and plexitis after ileocecal resection on the risk of postoperative recurrence. METHODS Using a systematic search, we identified. 30 studies evaluating the impact of inflammatory margins on CD recurrence. The primary outcome was the postoperative clinical recurrence and secondary outcomes were surgical, and endoscopic recurrence. We performed random-effects meta-analysis and estimated odds ratio (OR) and 95% CIs. RESULTS Thirty studies were analyzed, seven focused on myenteric plexitis, six on submucosal plexitis and twenty-three on positive margins. Inflammatory margins were associated with a higher rate of clinical and surgical recurrences: respectively 14 studies - OR 2.38; 95% CI, 1.54 - 3.68- I2 = 68.2%, Q test-p = 0.0003 and 8 studies - OR, 1.52; 95% CI, 1.07-2.16 - I2 =0%; Q test-p = 0.43. The presence of myenteric plexitis was associated with a higher rate of clinical recurrence (4 studies- OR, 1.60; 95%CI, 1.12-2.29; I2= 0%, Q-test-p = 0.61), and of endoscopic recurrence (4 studies - OR, 4.25; 95%CI; 2.06-8.76; I2= 0%, Q test-p = 0.97). Submucosal plexitis was not associated with an increased risk of endoscopic recurrence (4 studies - OR, 0.94; 95%CI; 0.58-1.52; I2= 0%, Q test-p = 0.79). CONCLUSION Inflammatory margins and/or plexitis were associated with postoperative recurrence after ileocecal resection for CD. These elements should be taken into account in future algorithm for prevention of postoperative recurrence.

Abstract
During the course of Crohn's disease, the response of mesenteric adipose tissue to the production of inflammatory mediators and bacterial invasion through the intestinal mucosa results in the formation of creeping fat. Creeping fat describes the arresting finger-like projections that surround the inflamed bowel. In this review, the microscopic and macroscopic features of creeping fat and histological evidence for the importance of this tissue are discussed. Moreover, the most recent insights into the radiological assessment of creeping fat in patients with Crohn's disease are reported. Advances in imaging techniques have revolutionized the possibility of visualization and quantification of adipose tissue depots with excellent accuracy. Visceral fat has been significantly correlated with various Crohn's-disease-related outcomes. Despite the difficulties in distinguishing physiologic perienteric fat from creeping fat, the growing interest in fat-wrapping in Crohn's disease has rejuvenated radiologic research. With regard to the noninvasive fat-wrapping assessment, a novel CT enterography-based mesenteric creeping fat index has been developed for the mitigation of the confounding effect of normal retroperitoneal and perienteric adipose tissue. Research on machine learning algorithms and computational radiomics in conjunction with mechanistic studies may be the key for the elucidation of the complex role of creeping fat in Crohn's disease.

Abstract
Advances in diagnostics of inflammatory bowel diseases (IBD) and improved treatment strategies allowed the establishment of new therapeutic endpoints. Currently, it is desirable not only to cease clinical symptoms, but mainly to achieve endoscopic remission, a macroscopic normalization of the bowel mucosa. However, up to one-third of IBD patients in remission exhibit persisting microscopic activity of the disease. The evidence suggests a better predictive value of histology for the development of clinical complications such as clinical relapse, surgical intervention, need for therapy escalation, or development of colorectal cancer. The proper assessment of microscopic inflammatory activity thus became an important part of the overall histopathological evaluation of colonic biopsies and many histopathological scoring indices have been established. Nonetheless, a majority of them have not been validated and no scoring index became a part of the routine bioptic practice. This review summarizes a predictive value of microscopic disease activity assessment for the subsequent clinical course of IBD, describes the most commonly used scoring indices for Crohn's disease and ulcerative colitis, and comments on current limitations and unresolved issues.

Abstract
PURPOSE To evaluate the role of the nucleotide oligomerization domain 2 (NOD2) mutation status and other risk factors for the incidence of postoperative complications after ileocolic resection for Crohn's disease (CD). METHODS Data of 138 patients consecutively undergoing ileocolic resection for CD at a tertiary academic referral center were retrospectively analyzed including single nucleotide polymorphism (SNP) data of the NOD2 gene. Uni- and multivariate regression analysis was performed to identify factors associated with increased risk of severe postoperative complications. RESULTS From 114 patients (83%), the NOD2 mutation status was available. Of these, 60 (53%) had a NOD2 wildtype, whereas eleven (10%) were homozygous for the high risk p.Leu1007fsX1008 (rs2066847) variant. Major postoperative complications occurred in 28 patients (20%). Twenty-seven of these (96%) were intraabdominal septic complications such as anastomotic leakage or abscess. Male gender (P = 0.029; OR 3.052, the duration of CD (time [months] from initial diagnosis of CD to surgery; P = 0.001; OR 1.009), previous abdominal surgery for CD (P = 0.017; OR 3.49), and the presence of enteric fistulas (P = 0.023; OR 3.21) were identified as independent risk factors for major postoperative complications. Homozygosity for the NOD2 high-risk variant p.Leu1007fsX1008 did not show increased postoperative morbidity in the short and long-term outcome. CONCLUSIONS We could detect independent risk factors for major postoperative complications after ileocolic resection for Crohn's disease. However, patients with the high-risk variant p.Leu1007fsX1008 of the NOD2 gene did not show increased postoperative morbidity.

Abstract
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.

Abstract
OBJECTIVE The primary aim of this study was to determine whether the microscopic presence of Crohn's disease (CD) in the resected specimen margins in patients undergoing ileocecectomy predicts disease recurrence. The secondary aim was to identify other risk factors which can predict recurrence. METHODS All CD patients who underwent ileocecectomy in a single colorectal unit between 2000 and 2015 were retrospectively evaluated. The diagnosis of CD and margin involvement status were retrieved from pathology reports. Recurrence was determined according to medical records or via a telephone questionnaire. Demographic, clinical, and surgical parameters were compared between patients with and without histopathologic evidence of CD in the resected margins. RESULTS A total of 202 CD patients were included, 49 with and 153 without evidence of microscopic involvement in the resected margins. The main demographic characteristics, surgical approach and procedure, and postoperative course, including medical treatment, clinical or endoscopic recurrence, and reoperation rates, were similar for both groups. Patients who were operated laparoscopically (n=58, p 0.016), conversion from laparoscopic to open (n=25, p 0.016), stapled anastomosis (n=150, p 0.004), when stricturoplasty was required (n=12, p 0.046), and those with perianal disease (n=32, p 0.045) had shorter time to recurrence. Male gender had increased hazard ratio (n=106, HR 1.38) for reoperation, but not significantly (p=0.058). CONCLUSIONS The presence of microscopic CD at the resected specimen margins was not associated with the risk of disease recurrence. Other demographic, clinical, and technical features that did correlate with early recurrence were identified. These results support a conservative approach to the extent of resection in CD patients undergoing ileocecectomy. TRIAL REGISTRATION Not relevant.

Abstract
INTRODUCTION Surgical resection is not curative in Crohn's disease (CD) and, recurrence after surgery is a common situation. The identification of patients at high risk of recurrence remains disappointing in clinical practice. OBJECTIVE To evaluate the impact of residual microscopic disease on margins on the risk of recurrence after ileocaecal resection in CD. PATIENTS AND METHODS All patients who underwent ileocaecal resection between January 1992 and December 2016 were prospectively identified. Demographic data, clinical, surgical and histological variables were retrospectively collected. Positive histologic margin was assessed prospectively and defined by the presence of acute inflammatory lesions on margins: erosion, ulceration, chorion infiltration by neutrophils, cryptic abscesses or cryptitis. RESULTS One hundred twenty five patients were included, with a median follow-up of 8 years (Interquartile Range (IQR), 4.3-15.2). Half (49.6%, n = 62) were women, and the median age at surgery was 33 years (IQR, 24-42). Fifty-six (44.8%) had positive inflammatory margins. Five years after surgery, respectively 29 (51%) and 23 (34%) patients with positive and negative margins had clinical recurrence (p = 0.034). At the end of the follow-up, respectively 60% (n = 34) and 47% (n = 33) patients had clinical recurrence (p = 0.07). CD-related hospitalizations were observed in respectively 37.5% (n = 21) and 18.8% (n = 13) with positive and negative margins (p = 0.02). Fourteen patients (25%) with positive intestinal margins had surgical recurrence at the end of the follow-up compared to 5 patients (7%) with negative margins (p = 0.04). Multivariate analysis confirmed that positive intestinal margin was independently associated with surgical recurrence (OR, 4.7 (CI95%, 1.4-15.3), p = 0.01). CONCLUSION Positive histologic margin was associated with an increased risk of clinical and surgical recurrence after ileocaecal resection for Crohn's disease.

Abstract
INTRODUCTION In Crohn's disease (CD), the assessment of transmural inflammation and fibrosis is of utmost importance. This study aimed to quantify these parameters in CD ileal specimens and correlate them with disease progression. METHODS This is a retrospective unicentric study based on the analysis of archived specimens (n = 103) of primary ileal resection. Data were retrieved from a prospective national inflammatory bowel disease registry. Two pathologists, blinded for CD phenotype and clinical indications for surgery, examined 3 sections per patient and graded inflammation and fibrosis, based on a histopathological score. RESULTS Penetrating (B3, n = 74) CD exhibited significantly higher inflammation in diseased areas, compared with stricturing (B2, n = 29) disease (score 3: 96% vs 76%, P = 0.005 in inflamed areas; 78% vs 55%, P = 0.019 in most affected areas). This was also observed for the comparison of B2 CD with B3 CD with (B3s, n = 54) and without associated stricture (B3o, n = 20): B3s vs B2: 81% vs 55%, P = 0.033 in most affected areas; B3o vs B2: 100% vs 76%, P = 0.006 in inflamed areas; 70% vs 55%, P = 0.039 in most affected areas. We could not show differences in fibrosis scores between the subphenotypes. Postoperative new penetrating events occurred only in B3s (n = 6, 11%, P = 0.043) patients. The changing of biologic therapy after surgery correlated with severe inflammation at the proximal ileal margin (55% changed vs 25% not changed, P = 0.035). DISCUSSION In our cohort, fibrosis scores and fibromuscular changes were comparable, irrespective of CD phenotype. Inflammation severity was the major differentiator between penetrating and stricturing disease.JOURNAL/cltg/04.03/01720094-202104000-00012/inline-graphic1/v/2021-04-13T161901Z/r/image-tiff.

Microscopic inflammation in ileocecal specimen does not correspond to a higher anastomotic leakage rate after ileocecal resection in Crohn's disease. PLoS One 2021; 16:e0247796. [PMID: 33661983 PMCID: PMC7932166 DOI: 10.1371/journal.pone.0247796] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2020] [Accepted: 02/12/2021] [Indexed: 12/15/2022] Open
Abstract
Background Patients with Crohn’s disease suffer from a higher rate of anastomotic leakages after ileocecal resection than patients without Crohn’s disease. Our hypothesis was that microscopic inflammation at the resection margins of ileocecal resections in Crohn’s disease increases the rate of anastomotic leakages. Patients and methods In a retrospective cohort study, 130 patients with Crohn’s disease that underwent ileocecal resection between 2015 and 2019, were analyzed. Anastomotic leakage was the primary outcome parameter. Inflammation at the resection margin was characterized as “inflammation at proximal resection margin”, “inflammation at distal resection margin” or “inflammation at both ends”. Results 46 patients (35.4%) showed microscopic inflammation at the resection margins. 17 patients (13.1%) developed anastomotic leakage. No difference in the rate of anastomotic leakages was found for proximally affected resection margins (no anastomotic leakage vs. anastomotic leakage: 20.3 vs. 35.3%, p = 0.17), distally affected resection margins (2.7 vs. 5.9%, p = 0.47) or inflammation at both ends (9.7 vs. 11.8%, p = 0.80). No effect on the anastomotic leakage rate was found for preoperative hemoglobin concentration (no anastomotic leakage vs. anastomotic leakage: 12.3 vs. 13.5 g/dl, p = 0.26), perioperative immunosuppressive medication (62.8 vs. 52.9%, p = 0.30), BMI (21.8 vs. 22.4 m2/kg, p = 0.82), emergency operation (21.2 vs. 11.8%, p = 0.29), laparoscopic vs. open procedure (p = 0.58), diverting ileostomy (31.9 vs. 57.1%, p = 0.35) or the level of surgical training (staff surgeon: 80.5 vs. 76.5%, p = 0.45). Conclusion Microscopic inflammation at the resection margins after ileocecal resection in Crohn’s disease is common. Histologically inflamed resection margins do not appear to affect the rate of anastomotic leakages. Our data suggest that there is no need for extensive resections or frozen section to achieve microscopically inflammation-free resection margins.

Abstract
BACKGROUND & AIMS Rates of postoperative Crohn's disease recurrence remain high, although the ability to predict this risk of recurrence remains limited. As such, we aimed to determine the association of histologic features at the time of resection with postoperative recurrence. METHODS Electronic databases were searched through February 2020 for studies that reported risk of clinical, endoscopic, or surgical postoperative recurrence in patients with positive resection margins, plexitis, or granulomas in the index specimen. Pooled risk ratios (RRs) with 95% CIs were calculated for this risk in patients with and without these histologic features. RESULTS Twenty-one studies (2481 patients) assessed positive resection margins, 10 studies (808 patients) assessed plexitis, and 19 studies (1777 patients) assessed granulomas. Positive resection margins increased the risk of clinical (RR, 1.26; 95% CI, 1.06-1.49; I2 = 41%) and surgical (RR, 1.87; 95% CI, 1.14-3.08; I2 = 71%) recurrence, with a trend toward endoscopic recurrence (RR, 1.56; 95% CI, 0.79-3.05; I2 = 85%). Granulomas increased the risk of clinical (RR, 1.31; 95% CI, 1.05-1.64; I2 = 36%) and endoscopic (RR, 1.37; 95% CI, 1.00-1.87; I2 = 49%) recurrence, with a trend toward surgical recurrence (RR, 1.58; 95% CI, 0.89-2.80; I2 = 75%). Plexitis increased the risk of endoscopic recurrence (RR, 1.31; 95% CI, 1.00-1.72; I2 = 20%), with a trend toward clinical recurrence (RR, 1.34; 95% CI, 0.95-1.91; I2 = 46%). CONCLUSIONS Positive resection margins, granulomas, and plexitis are predictive of postoperative Crohn's disease recurrence and should be recorded at the time of index resection.

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.

Abstract
BACKGROUND Resections for Crohn's disease should be limited and only resect macroscopically affected bowel. However, recent studies suggest microscopic inflammation at resection margins as a predictor for postoperative recurrence. The clinical impact remains unclear, as non-uniform pathological criteria have been used. The aim of this study was to assess the predictive value of pathological characteristics at ileocecal resection margins for recurrence. METHODS Both resection margins of 106 consecutive patients undergoing ileocecal resection for Crohn's disease between 2002 and 2009 were revised and scored for active inflammation, myenteric plexitis, and granulomas. Pathological findings were correlated to recurrence, defined as recurrent disease activity demonstrated by endoscopy (modified Rutgeerts score ≥i2) requiring upscaling medical treatment, using multivariate analysis. RESULTS Active inflammation was found at the proximal and distal resection margin in 27% and 15% of patients, respectively, myenteric plexitis in 37% and 32%, respectively, and granulomas in 4% and 6%, respectively. In total, 47 out of 106 patients developed recurrence. Only active inflammation at the distal colonic resection margin was an independent significant predictor for recurrence (88% vs 43% vs 51% for distal, proximal, and no involved margins, respectively; P < 0.01). CONCLUSION Active inflammation at the distal colonic resection margin after ileocecal resection identifies a patient group at high risk for postoperative recurrence both at the anastomotic site and the colon because it identifies undiagnosed L3 disease. These patients have a different and more aggressive natural history and require more intense medical treatment. Therefore, pathological evaluation of the distal resection margin should be implemented in daily practice.

Abstract
BACKGROUND The relative proportion of inflammation and fibrosis in a stricture is highly relevant in defining the clinical approach for Crohn's disease [CD] patients. Whereas transmural inflammation in CD can be accurately estimated by cross-sectional imaging, evaluating the extent and severity of fibrosis still requires surgical pathology of intestinal resection specimens. This study systematically reviewed all existing transmural histopathological scoring systems developed for the assessment of inflammation and/or fibrosis in CD. METHODS A systematic review of histopathological scoring systems for the assessment of transmural inflammation and/or fibrosis in CD, focusing on originally developed scoring systems. Risk of bias, methodological quality, and operating or psychometric properties [validity, reliability, responsiveness, and feasibility] of each histological scoring system were analysed. RESULTS A total of 29 original scoring systems were included in this review. Three scoring systems were highlighted as the most widely reproduced, one aimed at assessing inflammation only and two aimed at assessing inflammation and fibrosis. These scores were more widely reproduced probably due to their ease of application in clinical studies. Two highly comprehensive scores were identified, showing good operating properties and high methodological quality, as well as the lowest risk of bias; these should, therefore, be further validated in clinical research studies. CONCLUSIONS This study reviewed all existing transmural histopathological scoring systems for the assessment of inflammation and/or fibrosis in CD and identified the most reliable and accurate scores for clinical research and clinical practice settings.

Abstract
BACKGROUND Crohn's disease recurrence after ileocolic resection is common and graded with the Rutgeerts score. There is controversy whether anastomotic ulcers represent disease recurrence and should be included in the grading system. The aim of this study was to determine the impact of anastomotic ulcers on Crohn's disease recurrence in patients with prior ileocolic resections. Secondary aims included defining the prevalence of anastomotic ulcers, risk factors for development, and their natural history. METHODS We conducted a retrospective cohort study of patients undergoing an ileocolic resection between 2008 and 2017 at a large academic center, with a postoperative colonoscopy assessing the neoterminal ileum and ileocolic anastomosis. The primary outcome was disease recurrence defined as endoscopic recurrence (>5 ulcers in the neoterminal ileum) or need for another ileocolic resection among patients with or without an anastomotic ulcer in endoscopic remission. RESULTS One hundred eighty-two subjects with Crohn's disease and an ileocolic resection were included. Anastomotic ulcers were present in 95 (52.2%) subjects. No factors were associated with anastomotic ulcer development. One hundred eleven patients were in endoscopic remission on the first postoperative colonoscopy. On multivariable analysis, anastomotic ulcers were associated with disease recurrence (adjusted hazard ratio [aHR] 3.64; 95% CI, 1.21-10.95; P = 0.02). Sixty-six subjects with anastomotic ulcers underwent a second colonoscopy, with 31 patients (79.5%) having persistent ulcers independent of medication escalation. CONCLUSION Anastomotic ulcers occur in over half of Crohn's disease patients after ileocolic resection. No factors are associated with their development. They are associated with Crohn's disease recurrence and are persistent.

Mesenteric excision surgery or conservative limited resection in Crohn's disease: study protocol for an international, multicenter, randomized controlled trial. Trials 2020; 21:210. [PMID: 32085793 PMCID: PMC7035646 DOI: 10.1186/s13063-020-4105-x] [Citation(s) in RCA: 29] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2019] [Accepted: 01/22/2020] [Indexed: 12/14/2022] Open
Abstract
Background The structures of the mesentery including adipose tissue, nerves, and lymphatics play an important role in the pathogenesis and disease progression of Crohn’s disease (CD). Conventional surgical resection for CD usually does not involve resecting the mesentery en bloc with the specimen. This contrasts with complete mesocolic excision (CME) in colorectal cancer, which involves radical resection of the mesentery. Preliminary evidence from smaller studies suggests that applying the principle of mesocolic excision to CD surgery may reduce the risk of postoperative recurrence. This randomized controlled trial is designed to test whether applying the principles of mesocolic excision to CD results in reduced postoperative recurrence. It also aims to evaluate intra- and postoperative morbidity between the two approaches. Methods This international, multicenter, randomized controlled trial will randomize patients (n = 116) scheduled to undergo primary ileocolic resection to either receive extensive mesenteric excision (EME) or conventional ileocolic resection with limited mesenteric excision (LME). Five sites will recruit patients in three countries. In the EME group, the mesentery is resected following CME, while avoiding the root region, i.e., 1 cm from the root of the ileocolic artery and vein. In the LME group, the mesentery is retained, i.e., “close shave” or < 3 cm from the border of bowel. The primary end point will be surgical recurrence after surgery. The secondary end points will be the postoperative endoscopic and clinical recurrence, and intra- and postoperative morbidity. Demographics, risk factors, laboratory investigations, endoscopy, postoperative prophylaxis and imaging examination will be assessed. Analysis of the primary outcome will be on an intention-to-treat basis. Discussion If mesocolic excision in CD reduces postoperative disease recurrence and does not increase morbidity, this trial has the potential to change practice and reduce recurrence of CD after surgical resection.

Abstract
BACKGROUND AND AIMS Different types of histologic lesions at the ileal margin, detected by histology, have been associated with increased rates of recurrence after ileocaecal surgery in patients with Crohn's disease (CD). We aimed to characterize histologic features of the ileal margin and to evaluate their association with disease recurrence. METHODS We collected histologic data from 211 patients with ileal or ileocolonic CD who underwent ileocolonic resections at hospitals in France from September 2010 through December 2016. Ileal margins were analyzed. Early endoscopic recurrence was defined by a Rutgeerts score of i2 or more, 6 months after surgery. We also collected data from 10 adults with healthy ileum who underwent ileocecal resection for colonic tumors (controls). Clinical relapse was defined by CD-related symptoms confirmed by imaging, endoscopy, therapy intensification, CD-related complication, or subsequent surgery. RESULTS Six months after surgery, 49% of patients had endoscopic recurrence; 5 years after surgery, 57% of patients had clinical relapse. Ileal margins were macroscopically affected in 20.9% of patients. CD transmural lesions at the margin (defined by mucosal ulceration or cryptitis, submucosal fibrosis and lymphoplasmacytic infiltrate of the subserosa) were observed in 13.6% of patients. Endoscopic recurrence was observed in 75% of patients with CD transmural lesions vs 46% of patients without (P =.005). In multivariate analysis, CD transmural lesions at the margin were independently associated with early endoscopic recurrence (OR, 3.83; 95% CI, 1.47-11.05; P =.008) and clinical recurrence (OR 2.04; 95% CI, 1.09-3.99; P =.026). CONCLUSION In patients with CD, transmural lesions at the ileal margin were associated with an increased risk of post-operative recurrence. Histologic features of the ileal margin should be included in making decisions about post-operative therapy.

Abstract
BACKGROUND Despite significant advances in the medical management of Crohn's disease, many patients will require intestinal resection during their lifetime. It is disappointing that many will also develop disease recurrence. OBJECTIVES The current study utilizes meta-analytical techniques to determine the effect of positive histological margins at the time of index resection on disease recurrence. DATA SOURCES Embase, Medline, PubMed, PubMed Central, and Cochrane databases were searched using a Boolean search algorithm for articles published up to August 2017. STUDY SELECTION Meta-analysis was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. MAIN OUTCOME MEASURES Databases were searched for studies reporting the outcomes for patients with Crohn's disease undergoing primary resection that correlated resection margin status with disease recurrence. Results were reported as pooled ORs with 95% CI. RESULTS A total of 176 citations were reviewed; 18 studies comprising 1833 patients were ultimately included in the analysis, with a mean rate of histopathological margin positivity of 41.7 ± 17.4% and a pooled mean follow-up of 69 ± 39 months. Histopathological margin positivity was associated with a higher rate of overall recurrence (OR, 1.7; 95% CI, 1.3-2.1; p < 0.001), clinical recurrence (OR, 1.7; 95% CI, 1.0-2.8; p = 0.04), and anastomotic recurrence (OR, 1.6; 95% CI, 1.0-2.3; p = 0.03). In studies reporting plexitis specifically at the resection margin, there was an increase in recurrence (OR, 2.3; 95% CI, 1.1-4.9; p = 0.02). LIMITATIONS The definitions of histological margin positivity and postoperative recurrence vary between the studies and follow-up durations vary. CONCLUSIONS The presence of involved histological margins at the time of index resection in Crohn's disease is associated with recurrence, and plexitis shows promise as a marker of more aggressive disease. Further studies with homogeneity of histopathological and recurrence reporting are required.

Abstract
Anastomotic fibrosis is highly likely to lead to reoperation in Crohn's disease (CD) patients. Triptolide (TPL) is considered to have anti-inflammatory and antifibrotic effects in a variety of autoimmune diseases, including CD. The present study aimed to investigate the effects of TPL on fibroblasts from strictured ileocolonic anastomosis of patients with CD and its underlying mechanism. Primary fibroblasts were obtained from strictured anastomosis tissue (SAT) samples and matched anastomosis-adjacent normal tissue (NT) samples which were collected from 10 CD patients who underwent reoperation because of anastomotic stricture. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was used to measure miR-16-1 and heat shock protein 70 (HSP70) levels. Western blotting was conducted to determine expression of HSP70, collagen I (Col-I), collagen III (Col-III) and α-smooth muscle actin (α-SMA) proteins. Agomir-16-1 and antagomir-16-1 were used to up and downregulate the expression of miR-16-1, respectively. Small interfering RNA (siRNA) was employed to inhibit the expression of HSP70. A wound healing assay was performed to measure the migration of fibroblasts. Cell proliferation was evaluated by MTT and 5-bromo-2-deoxyrudidine assays. Cell apoptosis was determined by caspase-3 activity and TUNEL assays. The results demonstrated that the levels of Col-I, Col-III and α-SMA were all significantly upregulated in SAT compared with NT. miR-16-1 levels in the SAT group were significantly compared with the NT group; conversely, the expression levels of HSP70 mRNA and protein in the SAT group were significantly lower compared with the NT group. Next, fibroblasts were treated with TPL to examine its effect on the miR-16-1/HSP70 pathway. The results demonstrated that the elevated expression of miR-16-1 in the SAT group was effectively inhibited by TPL treatment. Compared with the NT group, both the mRNA and protein levels of HSP70 were significantly downregulated in the SAT group cells, while TPL exhibited a strong promoting effect on HSP70 synthesis. Furthermore, upregulation of miR-16-1 reversed the effect of TPL on the miR-16-1/HSP70 pathway in fibroblasts from SAT. Overexpression of miR-16-1 significantly reversed the inhibitory effects of TPL treatment on migration, proliferation and extracellular matrix (ECM)-associated protein expression of fibroblasts from SAT. Finally, downregulation of miR-16-1 caused similar effects to the fibroblasts as the TPL treatment; however, the inhibitory effects on cell biological functions induced by antagomir-16-1 were all significantly reversed by HSP70 silencing. The present findings indicated that TPL may be a potential therapeutic option for postoperative anastomosis fibrosis of patients with CD. The miR-16-1/HSP70 pathway had a substantial role in the inhibitory effects of TPL on migration, proliferation and ECM synthesis rate of fibroblasts from strictured anastomosis tissues.

Abstract
BACKGROUND AND AIMS Inclusion 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. METHODS Surgical 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. RESULTS Cumulative 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. CONCLUSIONS Inclusion of mesentery in ileocolic resection for Crohn's disease is associated with reduced recurrence requiring reoperation.

Abstract
OBJECTIVES Our study assessed whether the presence of histologically inflamed resection margins increased postoperative anastomotic complications in Crohn's disease (CD) patients. We also examined the influence of other risk factors for postoperative complications. MATERIALS AND METHODS Presence of chronic inflammation and activity of inflammation was scored from the resection margin specimens of 70 patients undergoing surgery due to CD. Anastomotic complications were recorded with a one-month follow-up. We also analysed other risk factors for postoperative complications, such as patient age, previous surgeries, preoperative C-reactive protein, faecal calprotectin, albumin and haemoglobin levels, American Society of Anesthesiologists (ASA) classification, preoperative immunosuppressive medication, surgical approach and the presence of intraoperative fistula or abscess. RESULTS In total, 46 patients (65.7%) had active inflammation in the bowel resection margin - 12 patients (17.1%) with mild, five patients (7.1%) with moderate and 29 patients (41.4%) with strong activity. We found 14 (20.0%) postoperative complications, of which three (4.6%) were anastomotic. The presence of active inflammation at the resection margin did not significantly influence the occurrence of postoperative anastomotic complications. None of the other risk factors examined significantly increased postoperative complications among our sample. CONCLUSIONS After bowel-sparing surgery for CD, the frequency of histologically inflamed resection margins is high. However, postoperative complication rate remains low. The current practice with resection of only the most affected bowel segments for CD seems to be a safe choice. We still need further research concerning risk factors for postoperative complications in Crohn's patients.

Abstract
Crohn disease (CD) is a chronic inflammatory bowel disease that affects the entire gastrointestinal tract. The standard treatment for CD is medication to control the inflammation and relieve the symptoms. CD patients often require surgery at some point in their life for complications, treatment resistance, and side effects of medication. However, postoperative recurrences are common. To reduce anastomotic troubles, several types of anastomosis were investigated. Kono-S anastomosis, an antimesenteric, functional, end-to-end handsewn anastomosis, was introduced in order to prevent the restenosis caused by recurrence of CD in 2010. Kono-S anastomosis is expected lower susceptibility to mechanical distortions due to the stability provided by the “supporting column.” We herein report 2 cases of CD performed with a Kono-S anastomosis. The importance of these cases is that Kono-S anastomosis is useful for preventing restenosis caused by recurrence. The first patient was a 26-year-old man who suffered from CD for 9 years. Computed tomography (CT) showed inflammation and stenosis at the ileocecum, a fistula between the terminal ileum and sigmoid colon, and an intraperitoneal abscess. We performed an ileocecal resection and a Kono-S anastomosis. The second patient was a 25-year-old woman who suffered from CD for 8 years. CT showed inflammation and stenosis at the ileocecum, and a retroperitoneal abscess. We performed an ileocecal resection and Kono-S anastomosis. Both patients showed no recurrence after surgery. Kono-S anastomosis may be effective for preventing recurrence at anastomotic sites in CD patients.

Abstract
INTRODUCTION We studied variables associated with outcomes following intestinal resection for Crohn's disease. METHODS A retrospective review of a prospectively maintained single surgeon database was performed. Outcomes evaluated included disease recurrence, need for further resection/dilatation, and complications. Explanatory variables included: anatomical region of resection, open or laparoscopic approach, surgical procedure, technique of anastomosis, number of anastomoses, use of biological therapy, resection margin disease, age at resection, and period (quartile) in series. RESULTS 81 children had 100 resections at a median age 14.5years with a median follow-up of 7.7years. Overall complication rate was 22%. Of the 77 children with no prior resection, 40 (52%) had disease recurrence, and 24 (31%) underwent further resection or dilatation. None of the explanatory variables predicted complications. Disease recurrence was significantly associated with younger age at first resection but not duration of follow-up. The probability of further intestinal intervention was strongly associated with disease site and complications. Odds ratio for further surgery for colonic disease site compared to ileocecal disease site was 7 (95% CI 1.8-26; P=0.004). Odds ratio for further intestinal resection following surgery where a complication had occurred compared to no complication was 3.4 (95% CI 1.1-10.3; P=0.02. Both disease site and complication status also significantly affected the interval to further surgery. CONCLUSIONS The probability of requiring a second intestinal intervention for pediatric Crohn's disease is related to the disease site and the complication status.

Abstract
One-third of patients with Crohn's disease (CD) present as stricturing phenotype characterized by progressive luminal narrowing and obstructive symptoms. The diagnosis and management of these patients have been intriguing and challenging. Immunomodulators and biologics have been successfully used in treating inflammatory and fistulizing CD. There are issues of efficacy and safety of biological agents in treating strictures in CD. Rapid mucosal healing from potent biological agents may predispose patients to the development of new strictures or worsening of existing strictures. On the other hand, strictures constitute one-fifth of the reasons for surgery in patients with CD. Disease recurrence is common at or proximal to the anastomotic site with the majority of these patients developing new endoscopic lesions within 1 year of surgery. The progressive nature of the disease with repetitive cycle of inflammation and stricture formation results in repeated surgery, with a risk of small bowel syndrome. There is considerable quest for bowel conserving endoscopic and surgical strategies. Endoscopic balloon dilation and stricturoplasty have emerged as valid alternatives to resection. Endoscopic balloon dilation has been shown to be feasible, safe, and effective for the short primary or anastomotic strictures. However, repeated dilations are often needed, and long-term outcomes of endoscopic balloon dilation remain to be investigated. The introduction of stricturoplasty has added another dimension to bowel saving strategy. Although postoperative recurrence rate after stricturoplasty is comparable with surgical resection, there are concerns for increased risk of malignancy in preserved bowel. Laparoscopic surgery has widely been performed with similar outcomes to open approach with fewer complications, quicker recovery, better cosmesis, and lower cost. All of these issues should be considered by physicians involved in the management of patients with stricturing CD.

Abstract
Recurrence of Crohn's disease (CD) after ileal or colonic resection is common. Many studies have tried to identify predictors of postoperative recurrence (POR) in CD. A wide range of histologic features have been identified, but for most of them, the literature provided conflicting data. In last years, several studies have suggested that histologic findings including inflammatory changes within the enteric nervous system of the resection margin may be associated with CD recurrence. Herein, after briefly summarizing pathophysiology of POR, we review all histological features that have been studied so far: granulomas, histologic appearance at the margin of resection, plexitis, lymphatic vessel density in proximal margin of resection, and morphological analysis of Paneth cells. Granulomas and chronic inflammation at the margin of resection do not seem to predict POR in CD. Active disease at the margin of resection, plexitis, lymphatic vessels density, morphological analysis of Paneth cells may predict POR. Most of these histological features await replication in independent studies. Available evidence indicates that histological findings may be taken into account when developing strategies aimed at preventing postoperative CD recurrence.

Abstract
BACKGROUND The aim of this investigation was to elucidate the clinical value of intraoperative enteroscopy (IOE) for Crohn's disease, and to determine the value of IOE in predicting recurrent disease. METHODS In this study 27 patients requiring surgery were examined by both preoperative radiography and IOE. The findings obtained by these procedures in the remnant small intestine were compared. In 19 patients, the clinical course and colonoscopic or radiographic findings after surgery were analyzed. RESULTS Intestinal lesions were identified in 23 patients by IOE, and in 19 patients by radiography. Longitudinal ulcers were equivalently detected by IOE (63%) and radiography (56%), whereas small ulcers and inflammatory polyps were less frequently detected by radiography than by IOE (37% vs 74% and 19% vs 33%, respectively). Neither the presence nor the distribution of IOE findings was related to postoperative recurrence. CONCLUSIONS Whereas IOE demonstrates small intestinal lesions in detail, the procedure alone cannot predict postoperative recurrence in Crohn's disease.

Abstract
Many patients with Crohn’s disease (CD) require surgery. Indications for surgery include failure of medical treatment, bowel obstruction, fistula or abscess formation. The most common surgical procedure is resection. In jejunoileal CD, strictureplasty is an accepted surgical technique that relieves the obstructive symptoms, while preserving intestinal length and avoiding the development of short bowel syndrome. However, the role of strictureplasty in duodenal and colonic diseases remains controversial. In extensive colitis, after total colectomy with ileorectal anastomosis (IRA), the recurrence rates and functional outcomes are reasonable. For patients with extensive colitis and rectal involvement, total colectomy and end-ileostomy is safe and effective; however, a few patients can have subsequent IRA, and half of the patients will require proctectomy later. Proctocolectomy is associated with a high incidence of delayed perineal wound healing, but it carries a low recurrence rate. Patients undergoing proctocolectomy with ileal pouch-anal anastomosis had poor functional outcomes and high failure rates. Laparoscopic surgery has been introduced as a minimal invasive procedure. Patients who undergo laparoscopic surgery have a more rapid recovery of bowel function and a shorter hospital stay. The morbidity also is lower, and the rate of disease recurrence is similar compared with open procedures.

Abstract
Introduction. Recently, the lymphatic vessels has been considered to play a key role in the pathophysiology and, consequently, in the treatment of Crohn’s disease (CD). The aim of this study is to show that the evaluation of lymphatic anomaly might be a useful tool in the recognition of the pathological involvement of the intestinal wall in CD. Material and methods. Fourteen patients with CD who underwent surgical treatment for distal ileum critical stenosis were prospectively evaluated. During surgery, 0.05 to 0.1 mL of Patent Blue V was injected into the subserosal layer of the antimesenteric edge of ileum and colon. The intestinal section was performed just beneath the outflow of the vital dye where it seemed to be normal (≤2 minutes), as a index of healthy intestinal wall. A comparison between the lymphatic alterations and the macroscopic aspects was performed. Results. Out of 14 patients, 13 were electively operated on, whereas 1 was treated in emergency. In 8 patients (57%), laparoscopic approach was chosen in the first instance. One patient needed laparotomic conversion. When comparing the Patent Blue V outflow time with the macroscopic and microscopic evidence of CD, we found an absolute integrity of the intestinal wall with an outflow ≤2 minutes. Mean follow-up was 110 months with a recurrence rate of 14%. Conclusion. We can conclude that this method may be of utility to distinguish between normal and diseased intestine in CD. The possible consequences in postsurgical recurrences of this evidence are critical.

Abstract
BACKGROUND Rates of postoperative complications are particularly high among patients with Crohn's disease. OBJECTIVE The aim of this study was to assess whether positive inflammatory histological margins, among other factors, pose a risk for intra-abdominal septic complications in patients with Crohn's disease undergoing ileocolic resection. DESIGN A retrospective study of patient records, during 2000-2010, was conducted. SETTINGS This investigation was performed at a single medical center. PATIENTS Included were 166 individuals with Crohn's disease (85 males, mean age 35.6). INTERVENTION Ileocolic resection with primary anastomosis was performed. MAIN OUTCOME MEASURE The primary outcomes measured were postoperative intra-abdominal septic complications. RESULTS Twenty-five patients (15%) developed intra-abdominal septic complications, including anastomotic leak, intra-abdominal abscesses and collections, and enterocutaneous fistulas. There were no postoperative deaths. Univariate analysis revealed that a long course of disease before surgery, an emergency surgery, steroid treatment of more than 3 months before surgery, additional sigmoidectomy, and positive surgical margins detected on histopathological examination were associated with intra-abdominal septic complications. In a multivariate analysis, only disease duration longer than 10 years (OR 4.575 (CI 1.592-13.142), p = 0.005), additional sigmoidectomy (OR 5.768 (CI 1.088-30.568), p = 0.04), and positive histological resection margins (OR 2.996 (CI 1.085-8.277), p = 0.03) were found to be independent risk factors. LIMITATIONS This study was limited by the incomplete data regarding preoperative albumin levels. CONCLUSIONS Positive histological margins, disease duration of more than 10 years, and added sigmoidectomy are independent risk factors that are associated with postoperative intra-abdominal septic complications in patients undergoing ileocolic resection for Crohn's disease. These risk factors should be considered when the need for a diverting stoma is questionable. A frozen section of the margins may assist in the decision as to a temporary ileostomy construction.

Abstract
Despite improved immunosuppressive therapy, surgical resection is still often required for uncontrolled inflammatory disease and the stenosing and perforating complications of Crohn's disease. However, surgery is not curative. A majority of patients develop disease recurrence at or above the anastomosis. Subclinical endoscopically identifiable recurrence precedes the development of clinical symptoms; identification and treatment of early mucosal recurrence may therefore prevent clinical recurrence. Therapy to achieve mucosal healing should now be the focus of postoperative therapy. A number of clinical risk factors for the development of earlier postoperative recurrence have been identified, and reasonable evidence is now available regarding the efficacy of drug therapies in preventing recurrence. This evidence now needs to be incorporated into prospective treatment strategies.

Abstract
BACKGROUND Stricturing Crohn's disease is accompanied by a high-risk for bowel resection and subsequent short bowel syndrome. Strictureplasty (SP) and endoscopic balloon dilatation (EBD) have been developed to prevent, or at least delay, the requirement for resection. The goal of this study was to compare the outcome of these two procedures with regard to complications and disease recurrence. METHODS We conducted a MEDLINE literature search to give a current overview about the safety and efficacy of EBD and SP. RESULTS The initial search yielded 744 articles. Case reports, reviews and meta-analyses were excluded. Finally, 63 articles (SP, 40 articles; EBD, 23 articles) were used for the review. None of the studies compared the two methods directly. A total of 2,532 patients (SP, n = 1,958; EBD, n = 574) were included. The incidence of perioperative complications after SP was 11% and the incidence of major complications was 5%. The median surgical recurrence rate was 24% after a median follow-up of 46 months. The median technical success for EBD was 90%. Major complications occurred in 3% of the cases. According to an intention-to-treat protocol, the median surgical recurrence rate was 27.6%. Per-protocol analysis revealed a median surgical recurrence rate of 21.4% after a median follow-up of 21 months. CONCLUSION Due to the lack of comparable data, there is currently no reliable information on whether one treatment option is superior to the other. Regarding the limited applicability of EBD in strictures of the small bowel, only a controlled trial would provide evidence as a basis for clinical decision making in CD strictures that are potentially treatable by EBD and SP.

Abstract
Restoration of the continuity of the intestinal tract is one of the key concepts for maintaining the quality of life in patients with Crohn's disease. Restorative procedures have an important role in the scope of operative modalities for these patients. The authors review operative options aimed at fulfilling these goals including restorative partial small bowel resection; segmental, subtotal, and total colectomies; and ileal pouch anal anastomosis in patients with Crohn's disease.

Abstract
Crohn's disease is an inflammatory disease of the gastrointestinal (GI) tract of uncertain etiology. It can affect any portion of the GI tract, involving the colon in approximately 60% of cases. Diagnosis can be unclear, but suspicion can be raised based upon clinical, endoscopic, and pathologic findings. Initial management is often medical, with surgery reserved for patients with colonic complications of Crohn's disease, such as hemorrhage, fulminant colitis, abscess or fistula, stricture, and malignant transformation. The operative choice and conduct depends upon the clinical presentation and intraoperative findings. The extent of resection is controversial, but segmental resection is appropriate in selected cases.

Abstract
With the advent of restorative proctocolectomy or ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC), not only has there been potential for cure of UC but also patients have enjoyed marked improvements in bowel function, continence, and quality of life. However, IPAA can be complicated by postoperative small bowel obstruction, disease recurrence, and pouch failure secondary to pelvic sepsis, pouch dysfunction, mucosal inflammation, and neoplastic transformation. These may necessitate emergent or expeditious elective reoperation to salvage the pouch and preserve adequate function. Local, transanal, and transabdominal approaches to IPAA salvage are described, and their indications, outcomes, and the clinical parameters that affect the need for salvage are discussed. Pouch excision for failed salvage reoperation is reviewed as well. Relaparotomy is also frequently required for recurrent Crohn's disease (CD), especially given the nature of this as yet incurable illness. Risk factors for CD recurrence are examined, and the various surgical options and margins of resection are evaluated with a focus on bowel-sparing policy. Stricturoplasty, its outcomes, and its importance in recurrent disease are discussed, and segmental resection is compared with more extensive procedures such as total colectomy with ileorectal anastomosis. Lastly, laparoscopy is addressed with respect to its long-term outcomes, effect on surgical recurrence, and its application in the management of recurrent CD.

Abstract
Inflammatory bowel disease (IBD) is an increasingly important cause of gastrointestinal pathology in children. Approximately 25% of IBDs present before the patient is 20 years of age. Accurate diagnosis and differentiation between Crohn's disease (CD) and ulcerative colitis (UC) is important in planning treatment strategies, particularly in children. Endoscopy, which allows direct visualization of gastrointestinal mucosa and biopsy of multiple sites, is an integral part of this diagnostic process. Although no endoscopic lesion is pathognomonic of IBD, certain features are highly suggestive of either CD or UC. In this article, we review and attempt to correlate endoscopic and histologic findings in IBD that have particular emphasis on the pediatric population.

Abstract
PURPOSE This study used meta-analytical techniques to compare the recurrence of granulomatous vs nongranulomatous Crohn disease. METHODS Comparative studies published between 1954 and 2007 of granulomatous vs nongranulomatous Crohn disease were included. Using a random effects model, end points evaluated were the number of recurrences and reoperations, and the time to recurrence and reoperation, of granulomatous vs nongranulomatous Crohn disease. Heterogeneity was assessed and sensitivity analysis was performed to account for bias in patient selection. RESULTS Twenty-one studies (14 nonrandomized retrospective, 7 nonrandomized prospective) reported on 2236 patients with Crohn disease, of whom 1050 (47.0%) had granulomas (granulomatous group) and 1186 (53.0%) had no granulomas (nongranulomatous group). The number of recurrences and reoperations was found to be significantly higher in the granulomatous group compared to the nongranulomatous group (odds ratio 1.37, P = .04; odds ratio 2.38, P < .001; respectively), with significant heterogeneity between studies (P = .06; P < .001; respectively). The time to recurrence and reoperation was significantly shorter in the granulomatous group compared with the nongranulomatous group (hazard ratio 1.63, P = .001; hazard ratio 1.62, P = .002; respectively), with no significant heterogeneity between studies. The number of recurrences and reoperations remained significantly higher in the granulomatous group compared to the nongranulomatous group during sensitivity analysis of higher-quality studies, more recent studies, and studies with a larger group of patients. CONCLUSIONS Granulomatous Crohn disease appears to be associated with a higher number of recurrences and reoperations and a shorter time to recurrence and reoperation compared to nongranulomatous Crohn disease. Because of significant heterogeneity between studies, further studies should be undertaken to confirm these findings.

Abstract
PURPOSE This study attempts to determine whether stapled side-to-side anastomosis, compared with handsewn end-to-end anastomosis, results in decreased recurrence of Crohn's disease following ileocolic resection. METHODS Patients with Crohn's disease who underwent an ileocolic resection were randomized to side-to-side anastomosis or end-to-end anastomosis. Colonoscopy was performed at 12 months. The primary outcome was endoscopic recurrence, while the secondary outcome was symptomatic recurrence (defined as symptoms attributable to Crohn's disease and severe enough to warrant treatment, plus endoscopic disease recurrence). RESULTS One hundred and thirty-nine subjects were included in the efficacy analysis. After a mean follow-up of 11.9 months, the endoscopic recurrence rate was 42.5 percent in the end-to-end anastomosis group, compared with 37.9 percent in the side-to-side anastomosis group (-4.6 percent difference; 95 percent confidence interval -21.0 to 11.9 percent; P = 0.55). The symptomatic recurrence rate was 21.9 percent in the end-to-end anastomosis group, compared with 22.7 percent in the side-to-side anastomosis group (+0.8 percent difference; 95 percent confidence interval -13.2 to 15.3 percent; P = 0.92). In multivariate logistic regression analysis, previous resections were predictive of a higher risk of both endoscopic (odds ratio 1.78; 95 percent confidence interval 1.06 to 2.90; P = 0.028) and symptomatic (odds ratio 2.0; 95 percent confidence interval 1.14 to 3.60; P = 0.0016) recurrence. Compliance with postoperative maintenance therapy was predictive of a lower risk of symptomatic recurrence (odds ratio 0.13, 95 percent confidence interval 0.01 to 0.78; P = 0.021). CONCLUSION Recurrence rates are similar whether end-to-end anastomosis or side-to-side anastomosis is performed.

Abstract
Crohn's disease is a chronic inflammatory condition that may involve any segment of the gastrointestinal tract. Although several drugs have proven efficacy in inducing and maintaining disease in remission, resectional surgery remains as a cornerstone in the management of the disease, mainly for the treatment of its stenosing and penetrating complications. However, the occurrence of new mucosal (endoscopic) lesions in the neoterminal ileum early after surgery is almost constant, it is followed in the mid-term by clinical symptoms and, in a proportion of patients, repeated intestinal resections are required. Pathogenesis of postoperative recurrence (POR) is not fully understood, but luminal factors (commensal microbes, dietary antigens) seem to play an important role, and environmental and genetic factors may also have a relevant influence. Many studies tried to identify clinical predictors for POR with heterogeneous results, and only smoking has repeatedly been associated with a higher risk of POR. Ileocolonoscopy remains as the gold standard for the assessment of appearance and severity of POR, although the real usefulness of the available endoscopic score needs to be revisited and alternative techniques are emerging. Several drugs have been evaluated to prevent POR with limited success. Smoking cessation seems to be one of the more beneficial therapeutic measures. Aminosalicylates have only proved to be of marginal benefit, and they are only used in low-risk patients. Nitroimidazolic antibiotics, although efficient, are associated with a high rate of intolerance and might induce irreversible side effects when used for a long-term. Thiopurines are not widely used after ileocecal resection, maybe because some concerns in giving immunomodulators in asymptomatic patients still remain. In the era of biological agents and genetic testing, a well-established preventive strategy for POR is still lacking, and larger studies to identify good clinical, serological, and genetic predictors of early POR as well as more effective drugs (or drug combinations) are needed.

Abstract
BACKGROUND Strictureplasty is an alternative surgical procedure for Crohn's disease, particulary in patients with previous resections or many intestinal stenosis. AIM To analyze surgical complications and clinical follow-up in patients submitted to strictureplasty secondary to Crohn's disease. METHODS Twenty-eight patients (57.1% male, mean age 33.3 years, range 16-54 years) with Crohn's disease and intestinal stenosis (small bowel, ileocecal region and ileocolic anastomosis) were submitted to strictureplasty, at one institution, between September 1991 and May 2004. Thirteen patients had previous intestinal resections. The mean follow-up was 58.1 months. A total of 116 strictureplasties were done (94 Heineke-Mikulicz--81%, 15 Finney--13%, seven side-to-side ileocolic strictureplasty--6%). Three patients were submitted to strictureplasty at two different surgical procedures and two in three procedures. RESULTS Regarding to strictureplasty, postoperative complication rate was 25% and mortality was 3.6%. Early local complication rate was 57.1%, with three suture leaks (10.7%) and late complication was present in two patients, both with incisional hernial and enterocutaneous fistulas (28.6%). Patients remained hospitalized during a medium time of 12.4 days. Clinical and surgical recurrence rates were 63% and 41%, respectively. Among the patients submitted to another surgery, two patients had two more operations and one had three. Recurrence rate at strictureplasty site was observed in 3.5%, being Finney technique the commonest one. Presently, 19 patients had been asymptomatic with the majority of them under medical therapy. CONCLUSION Strictureplasties have low complication rates, in spite of having been done at compromised site, with long term pain relief. Considering the clinical course of Crohn's disease, with many patients being submitted to intestinal resections, strictureplasties should be considered as an effective surgical treatment to spare long intestinal resections.

Abstract
AIM To compare postoperative adverse events and recurrence following strictureplasty or bowel resection in patients with small bowel Crohn's disease (CD). METHOD A literature search was performed to identify studies published between 1980 and 2006 comparing outcomes of CD patients undergoing either strictureplasty or bowel resection. Hazard ratios were calculated from Kaplan-Meier plots of cumulative recurrence data. Quality assessment of the included studies was performed. Random-effect meta-analytical techniques were employed. Sensitivity analysis and assessment of heterogeneity were performed. RESULTS Seven studies comprising 688 CD patients (strictureplasty n = 311, 45%; resection with or without strictureplasty n = 377, 55%) were included. Patients undergoing strictureplasty alone had a lower risk of developing postoperative complications than those who underwent resection (OR = 0.60, 95% CI: 0.31-1.16) although this was not statistically significant (P = 0.13). Surgical recurrence after strictureplasty was more likely than after resection (OR = 1.36, 95% CI: 0.96-1.93, P = 0.09). Patients who had a resection had a significantly longer recurrence-free survival than those undergoing strictureplasty alone (HR = 1.08, 95% CI: 1.02-1.15, P = 0.01). CONCLUSION Patients with small bowel CD undergoing strictureplasty alone may have fewer postoperative complications than those undergoing a concomitant bowel resection. However, surgical recurrence maybe higher following strictureplasty alone than with a concomitant small bowel resection. Patients may require appropriate preoperative counselling regarding the pros and cons of each operative technique.

Abstract
Inflammatory bowel disease (IBD) is a general term used to describe two chronic bowel disorders, Crohn's disease (CD) and ulcerative colitis (UC), both of which are characterized by autoimmune-related inflammation of the intestines. UC is limited to the colonic mucosa, whereas CD can involve any part of the intestinal tract from the mouth to the anus. The true etiology of UC and CD is still unknown, although extensive research has identified some genetic and environmental factors. This article discusses current clinical concepts of both diseases in the pediatric population.

Abstract
BACKGROUND & AIMS Early ileocolonoscopy allows detection of recurrence after surgically induced remission of Crohn's disease (CD). Unequivocal histologic markers predicting recurrence have not been identified. We assessed the predictive value of neural lesions for early endoscopic CD recurrence and long-term reintervention risk. METHODS Ileocolonic resection specimens from 59 patients with CD and 21 control patients were histologically scored for typical inflammatory bowel disease lesions, neural hypertrophy, and presence and severity of inflamed ganglia and nerve bundles. Endoscopic recurrence was determined at 3 months in all patients and at 1 year in 32 patients as part of 2 prospective clinical trials. RESULTS Myenteric plexitis of the proximal resection margin was present in 32 patients with CD (54%) in absence of surrounding inflammation. Patients with this feature had a higher endoscopic recurrence (Rutgeerts score >/=2) at 3 months (75% vs 41%; odds ratio, 4.36; 95% confidence interval, 1.44-13.23; P = .008) and at 1 year (93% vs 59%; odds ratio, 9.80; 95% confidence interval, 1.04-92.70; P = .041) and had a trend toward an earlier reintervention (mean, 7.00 vs 5.30 years; P = .174). The severity of myenteric plexitis in the proximal resection margin correlated with the severity of endoscopic recurrence at 3 months (r = 0.334, P = .010) and 1 year (r = 0.560, P = .001). Myenteric plexitis was the only consistent predictor of endoscopic recurrence. CONCLUSIONS The presence of myenteric plexitis in proximal margins of ileocolonic resection specimens is predictive of early endoscopic CD recurrence.

Abstract
More than three quarters of patients with Crohn's disease (CD) will require surgery. After resection, disease recurs postoperatively with a median time to second resection of about 10 years. Despite its importance, the postoperative period remains one of the most poorly understood clinical settings in the field. Postoperatively, CD may exhibit unique pathophysiologic features, but the current state of knowledge does not allow for identification of patients at risk for relapse, and leaves clinicians without guidance on optimal maintenance treatment. Therapies used as maintenance for CD in other settings may have different efficacies when used after surgery, and clinical research in patients requiring surgery is limited by the subset of patients available for study. Despite the many limitations in current knowledge of postoperative CD, it is an exciting field because new developments have improved patient care, and ongoing research has the potential for further gains.

Abstract
Several standardized types of colonic resections are available in the clinical practice. All of them may produce early and late complications. Diagnostic imaging plays a pivotal role in the recognition of post-operative colorectal complications and provides fundamental information for therapeutic planning. In this paper we review the imaging findings of early and late post-operative complications of colorectal surgery.

Abstract
BACKGROUND Colonic Crohn's disease can be treated surgically by total colonic resection or by segmental colonic resection. The aim of this study was to analyze the outcomes of patients treated by segmental colectomy for colonic Crohn's disease. STUDY DESIGN Among 413 patients undergoing operations for Crohn's disease, 84 had a segmental colectomy (cases of terminal ileitis with limited cecal involvement were not included). Postoperative complications, mortality, recurrence, and functional results were studied. RESULTS Eighty-four patients (51 women, 33 men), with a mean age of 34 years, underwent operation (right segmental colectomy: 55%; left segmental colectomy: 40%; associated right and left colectomy: 5%). A stoma was established in 27 patients (32%). Operative mortality was zero. Twelve patients (14%) had postoperative complications (including six cases of anastomotic leakage). The mean and median followup times were 111 and 104 months, respectively (range: 15 to 276 months) for the 82 patients with followup available. Thirty-six patients had to undergo reoperation, and the mean time to reoperation was 4.5 years. Twenty-six of these patients suffered colonic recurrence and were treated by total colectomy (n = 9) or new segmentary resection (n 17). The only factor that correlated with the risk of recurrence was youth. At the end of the study, 13 patients still had a stoma. Seventy-five percent of the patients without stoma had less than three bowel movements per day, and 80% were fully satisfied or satisfied, CONCLUSIONS There is no evidence of a higher risk of postoperative complications, surgical recurrence, or the requirement of a permanent stoma in patients suffering from colonic Crohn's disease who are treated according to a "bowel-sparing policy" compared with patients treated with more extensive resections published in the literature. Prospective randomized studies are needed to validate this observation.
