Abstract
BACKGROUND Evidence suggests inflammatory mesenteric fat is involved in post-operative recurrence (POR) of Crohn's disease (CD). However, its prognostic value is uncertain, in part, due to difficulties studying it non-invasively. AIM To evaluate the prognostic value of pre-operative radiographic mesenteric parameters for early endoscopic POR (ePOR). METHODS We conducted a retrospective cohort study of CD subjects ≥ 12 years who underwent ileocecal or small bowel resection between 1/1/2007 to 12/31/2021 with computerized tomography abdomen/pelvis ≤ 6 months pre-operatively and underwent ileocolonoscopy ≤ 15 months post-operatively. Visceral adipose tissue (VAT) volume (cm3), ratio of VAT:subcutaneous adipose tissue (SAT) volume, VAT radiodensity, and ratio of VAT:SAT radiodensity were generated semiautomatically. Mesenteric lymphadenopathy (LAD, largest lymph node > 10 mm) and severe vasa recta (VR) engorgement (diameter of the VR supplying diseased bowel ≥ 2 × VR supplying healthy bowel) were derived manually. The primary outcome was early ePOR (Rutgeert's score ≥ i2 on first endoscopy ≤ 15 months post-operatively) and the secondary outcome was ePOR severity (Rutgeert's score i0-4). Regression analyses were performed adjusting for demographic and disease-related characteristics to calculate adjusted odds ratio (aOR) and 95% confidence interval (CI). RESULTS Of the 139 subjects included, 45% of subjects developed early ePOR (n = 63). VAT radiodensity (aOR 0.59, 95%CI: 0.38-0.90) and VAT:SAT radiodensity (aOR 8.54, 95%CI: 1.48-49.28) were associated with early ePOR, whereas, VAT volume (aOR 1.23, 95%CI: 0.78-1.95), VAT:SAT volume (aOR 0.80, 95%CI: 0.53-1.20), severe VR engorgement (aOR 1.53, 95%CI: 0.64-3.66), and mesenteric LAD (aOR 1.59, 95%CI: 0.67-3.79) were not. Similar results were observed for severity of ePOR. CONCLUSION VAT radiodensity is potentially a novel non-invasive prognostic imaging marker to help risk stratify CD patients for POR.

Abstract
BACKGROUND The comparative safety and effectiveness of available biologics for post-operative prophylaxis in Crohn's disease (CD) is uncertain. Drug persistence may serve as a real-world proxy for tolerability and effectiveness. We evaluated the comparative persistence of non-TNF and TNF antagonists for post-operative prophylaxis and their comparative effectiveness for preventing early endoscopic post-operative recurrence (POR). METHODS We conducted a single-center, retrospective study of surgically naïve CD subjects undergoing ileocecal or small bowel resection between 1/1/2000 and 12/31/2021 and prescribed a biologic for post-operative prophylaxis. We compared the risk of prophylaxis failure (requiring recurrent surgery or discontinuation of therapy due to persistent POR despite optimized drug level or dose escalation, immunogenicity, and/or adverse event) and early endoscopic POR (Rutgeert's score ≥ i2 within 15 months postoperatively) between non-TNF and TNF antagonist prophylaxis using Cox proportional hazard and logistic regression, respectively, adjusting for demographic and disease characteristics. RESULTS The study included 291 subjects (81% TNF antagonists). After multivariable adjustment, non-TNF antagonist prophylaxis was associated with a significantly lower risk of prophylaxis failure than TNF antagonists (hazard ratio 0.26; 95% confidence interval (CI) [0.13-0.53]). Prophylaxis with non-TNF and TNF antagonists had similar risk of early endoscopic POR (odds ratio 0.66; 95% CI [0.32-1.36]). Stratifying the non-TNF antagonists by anti-integrin and anti-IL12/23 yielded similar results. CONCLUSION In a cohort of surgically naïve CD subjects prescribed a biologic for post-operative prophylaxis, non-TNF antagonists had greater persistence than TNF antagonists with similar risk for early endoscopic POR. If confirmed by large, prospective studies, these findings can inform post-operative management strategies in CD.

Abstract
BACKGROUND Outcomes after ileocolonic resection in Crohn's Disease (CD) are heterogeneous and a clear definition of postoperative recurrence remains to be determined. Our Endpoints Working Group of the International Organization for the study of Inflammatory Bowel Disease (IOIBD) aimed to standardize postoperative outcomes, to discuss which endpoints should be used for postoperative clinical trials and to define those which could be used in trials or registries. METHODS Based on a systematic review of the literature, recommendations and statements were drafted and sent to all IOIBD members for a first round of voting. Recommendations and statements were revised based on the voters' comments during a consensus hybrid conference open to all IOIBD members. If no agreement was reached after 2 rounds of voting, the statement was excluded. RESULTS In the systematic review, 3,071 manuscripts were screened, of which 434 were included. Sixteen recommendations were identified, of which 11 were endorsed. Recommendations and statements include that endoscopy remains the gold standard and should be used as a short-term primary endpoint in both observational cohorts and randomized controlled trials. Clinical symptoms classically used in clinical trials for luminal CD are not reliable in this specific situation. For that reason, longer term endpoints should be based on the evidence of macroscopic inflammation assessed by imaging techniques, endoscopy or reflected by the presence of complications. CONCLUSIONS Agencies recommend the use of clinical evaluations, as in the case of luminal CD, and do not recognize primary endpoints based solely on endoscopy. This consensus has led to agreement on the need to define postoperative endoscopy- and/or imaging-based endpoints.

Abstract
OBJECTIVE Perianal Crohn's disease (pCD) occurs in up to 40% of patients with CD and is associated with poor quality of life, limited treatment responses and poorly understood aetiology. We performed a genetic association study comparing CD subjects with and without perianal disease and subsequently performed functional follow-up studies for a pCD associated SNP in Complement Factor B (CFB). DESIGN Immunochip-based meta-analysis on 4056 pCD and 11 088 patients with CD from three independent cohorts was performed. Serological and clinical variables were analysed by regression analyses. Risk allele of rs4151651 was introduced into human CFB plasmid by site-directed mutagenesis. Binding of recombinant G252 or S252 CFB to C3b and its cleavage was determined in cell-free assays. Macrophage phagocytosis in presence of recombinant CFB or serum from CFB risk, or protective CD or healthy subjects was assessed by flow cytometry. RESULTS Perianal complications were associated with colonic involvement, OmpC and ASCA serology, and serology quartile sum score. We identified a genetic association for pCD (rs4151651), a non-synonymous SNP (G252S) in CFB, in all three cohorts. Recombinant S252 CFB had reduced binding to C3b, its cleavage was impaired, and complement-driven phagocytosis and cytokine secretion were reduced compared with G252 CFB. Serine 252 generates a de novo glycosylation site in CFB. Serum from homozygous risk patients displayed significantly decreased macrophage phagocytosis compared with non-risk serum. CONCLUSION pCD-associated rs4151651 in CFB is a loss-of-function mutation that impairs its cleavage, activation of alternative complement pathway, and pathogen phagocytosis thus implicating the alternative complement pathway and CFB in pCD aetiology.

Abstract
BACKGROUND & AIMS We compared the safety and effectiveness of tumor necrosis factor α (TNF-α) antagonists vs vedolizumab vs ustekinumab in patients with Crohn's disease (CD) in a multicenter cohort (CA-IBD). METHODS We created an electronic health record-based cohort of adult patients with CD who were initiating a new biologic agent (TNF-α antagonists, ustekinumab, vedolizumab) from 5 health systems in California between 2010 and 2017. We compared the risk of serious infections (safety) and all-cause hospitalization and inflammatory bowel disease-related surgery (effectiveness) between different biologic classes using propensity score (PS) matching. RESULTS As compared with TNF-α antagonists (n = 1030), 2:1 PS-matched, ustekinumab-treated patients with CD (n = 515) experienced a lower risk of serious infections (hazard ratio [HR], 0.36; 95% CI, 0.20-0.64), without any difference in the risk of hospitalization (HR, 0.99; 95% CI, 0.89-1.21) or surgery (HR, 1.08; 95% CI, 0.69-1.70). Compared with vedolizumab (n = 221), 1:1 PS-matched, ustekinumab-treated patients with CD (n = 221) experienced a lower risk of serious infections (HR, 0.20; 95% CI, 0.07-0.60), without significant differences in risk of hospitalization (HR, 0.76; 95% CI, 0.54-1.07) or surgery (HR, 1.42; 95% CI, 0.54-3.72). Compared with TNF-α antagonists (n = 442), 2:1 PS-matched, vedolizumab-treated patients with CD (n = 221) had a similar risk of serious infections (HR, 1.53; 95% CI, 0.84-2.78), hospitalization (HR, 1.32; 95% CI, 0.98-1.77), and surgery (HR, 0.63; 95% CI, 0.27-1.47). High comorbidity burden, concomitant opiate use, and prior hospitalization were associated with serious infections and hospitalization in biologic-treated patients with CD. CONCLUSION In a multicenter cohort of biologic-treated patients with CD, ustekinumab was associated with a lower risk of serious infections compared with TNF-α antagonists and vedolizumab, without any differences in risk of hospitalization or surgery. The risk of serious infections was similar for TNF-α antagonists vs vedolizumab.

Abstract
Perianal Crohn's disease affects 25%-35% of patients with Crohn's disease and has proven to be one of the most difficult complications of the disease to treat. Patients with perianal Crohn's disease have lower health-related quality of life scores typically related to pain and fecal incontinence. In addition, patients with perianal Crohn's disease have higher rates of hospitalizations, surgeries, and overall healthcare costs. A multidisciplinary approach is necessary for the successful management of Crohn's disease with perianal fistula. Medical management is required to treat the underlying immune dysregulation to heal the luminal inflammation and the inflammation within the fistula tracts. Current options for medical therapy include biologics, dual therapy with thiopurines, therapeutic drug monitoring, and a close follow-up. Surgical management is critical to drain abscesses before immunosuppressive therapy and place setons when appropriate. Once the patient's inflammatory burden is well managed, definitive surgical therapies including fistulotomies, advancement flaps, and ligation of intersphincteric fistula tract procedures can be considered. Most recently, the use of stem cell therapy in the treatment of perianal fistula has given new hope to the cure of perianal fistula in Crohn's disease. This review will outline the most current data in the medical and surgical management of perianal Crohn's disease.

Abstract
BACKGROUND Crohn's disease is considered a contraindication for IPAA. In our prior study, when IPAA was used intentionally for well-defined Crohn's disease, we found a high incidence of recurrent disease with a low incidence of pouch failure. OBJECTIVE This study aimed to replicate these findings in a larger cohort over a longer period. DESIGN Retrospective review of a prospective IBD registry. SETTINGS Large IBD referral center. PATIENTS Patients with preoperative colorectal Crohn's disease requiring surgery were included in the study. INTERVENTION IPAA. MAIN OUTCOME MEASURES Long-term Crohn's disease recurrence, pouch failure, and pouch function. RESULTS Forty-six patients were identified. Crohn's disease was diagnosed on the basis of perianal disease (n = 18; 39%), small-bowel disease (n = 16; 35%), noncaseating granuloma (n = 10; 22%), and discontinuous inflammation (colorectal skip lesions) (n = 11; 24%). After a median follow-up of 93 (7-291) months, 22 patients (48%) developed recurrent Crohn's disease based on afferent limb disease (n = 14; 30%) or pouch fistulizing disease (n = 8; 18%). Only 4 patients (9%) developed pouch failure. No clinical factor was associated with Crohn's disease recurrence. Young age at the time of surgery and short duration of disease before IPAA were associated with pouch fistula recurrence ( p = 0.003 and p = 0.03, respectively). Most patients (86%) reported excellent continence, with no urgency (67%) and median stool frequency of 6 (range, 3-9) per day. LIMITATION Retrospective nature and relatively small sample size. CONCLUSION This largest reported series examining the intentional use of IPAA in Crohn's disease showed a high (48%) incidence of postoperative Crohn's disease with a low (9%) incidence of pouch failure. Young age and short disease course before surgery were risk factors for poor outcomes. Highly motivated patients with colorectal Crohn's disease may consider IPAA and avoid a definitive ileostomy.

RESULTADOS A LARGO PLAZO Y FACTORES PREDICTORES DE RESULTADOS DE LA ANASTOMOSIS ILEOANAL CON RESERVORIO CUANDO SE USA INTENCIONALMENTE PARA LA ENFERMEDAD DE CROHN BIEN DEFINIDA ANTECEDENTES: La enfermedad de Crohn (EC) se considera una contraindicación para la anastomosis ileoanal con reservorio (IPAA). Nuestro estudio previo de IPAA cuando fue usada intencionalmente para EC bien definida mostró una alta incidencia de enfermedad recurrente con una baja incidencia de falla del reservorio.OBJETIVO: Replicar estos hallazgos en una cohorte más grande durante un período más largo.DISEÑO: Revisión retrospectiva de una base de datos prospectiva de enfermedad inflamatoria intestinal.ESCENARIO: Un centro grande de referencia de EII.PACIENTES: EC colorrectal preoperatoria con necesidad de tratamiento quirúrgico.INTERVENCIÓN: Anastomosis ileoanal con reservorio.RESULTADOS PRINCIPALES: Recurrencia de EC a largo plazo, falla del reservorio y función del reservorio.RESULTADOS: Cuarenta y seis pacientes fueron identificados. El diagnóstico de EC se basó en enfermedad perianal (n = 18; 39%), enfermedad del intestino delgado (n = 16; 35%), granuloma no caseificante (n = 10; 22%) e inflamación discontinua (lesiones salteadas colorrectales) (n = 11; 24%). Después de una mediana de seguimiento de 93 (7-291) meses, 22 (48 %) pacientes desarrollaron EC recurrente debido a enfermedad del asa aferente (n = 14; 30%) o enfermedad fistulizante del reservorio (n = 8; 18%). Solo 4 (9%) pacientes desarrollaron falla del reservorio. Ningún factor clínico se asoció con la recurrencia de EC. La edad joven en el momento de la cirugía y la corta duración de la enfermedad antes de IPAA se asociaron con la recurrencia de la fístula del reservorio ( p = 0.003 y p = 0.03, respectivamente). El recuento de plaquetas preoperatorio más alto fue la única característica clínica significativamente asociada con el fracaso del reservorio ( p = 0.02). La mayoría de los pacientes (86%) reportaron una continencia excelente, sin urgencia (67%) y una mediana de frecuencia evacuatoria de 6 (rango, 3-9) por día.LIMITACIONES: Naturaleza retrospectiva y tamaño de muestra relativamente pequeño.CONCLUSIÓN: Esta serie, la más grande reportada que examina el uso intencional de IPAA en la EC mostró una incidencia alta (48Rectal Cancer: Clinical and Molecular Predictors of a Complete Response to Total Neoadjuvant Therapy%) de EC posoperatoria con una incidencia baja (9%) de falla del reservorio. La edad joven y el curso corto de la enfermedad antes de la cirugía fueron factores de riesgo para pobres resultados. Pacientes altamente motivados con EC colorrectal pueden considerar una IPAA y evitar una ileostomía permanente. Consulte Video Resumen en http://links.lww.com/DCR/C171 .

Abstract
Objective To discover if first-attempt failure of the American Board of Colon and Rectal Surgery (ABCRS) board examination is associated with surgical training or personal demographic characteristics. Methods Current colon and rectal surgery program directors in the United States were contacted via email. Deidentified records of trainees from 2011 to 2019 were requested. Analysis was performed to identify associations between individual risk factors and failure on the ABCRS board examination on the first attempt. Results Seven programs contributed data, totaling 67 trainees. The overall first-time pass rate was 88% (n = 59). Several variables demonstrated potential for association, including Colon and Rectal Surgery In-Training Examination (CARSITE) percentile (74.5 vs 68.0, P = 0.09), number of major cases in colorectal residency (245.0 vs 219.2, P = 0.16), >5 publications during colorectal residency (75.0% vs 25.0%, P = 0.19), and first-time passage of the American Board of Surgery certifying examination (92.5% vs 7.5%, P = 0.18). Conclusion The ABCRS board examination is a high-stakes test, and training program factors may be predictive of failure. Although several factors showed potential for association, none reached statistical significance. Our hope is that by increasing our data set, we will identify statistically significant associations that can potentially benefit future trainees in colon and rectal surgery.

Abstract
BACKGROUND There are reported variations in the intraoperative management of Crohn's disease. This consensus statement aimed to develop a standardised protocol for photographic documentation of intraoperative findings and critical procedural steps in ileocolonic Crohn's disease surgery. METHODS Colorectal surgeons with a specialist interest in minimally invasive surgery and inflammatory bowel disease were invited as committee members to develop a survey on the use of photo-documentation in Crohn's disease surgery. A 15 item survey was developed on ethical considerations and applications of photo-documentation in audit and quality control, research, and training. RESULTS There was strong agreement on the potential application of intraoperative photo-documentation in Crohn's disease for training, research, quality control and tertiary referrals. Reviewers agreed that intraoperative staging required photo-documentation of strictures, skip lesions, perforations, fat wrapping and mesenteric disease. The necessary steps to be photo-documented were very specific to Crohn's disease surgery, such as views of anastomosis and strictureplasties, and extent of resection(s). CONCLUSIONS Our consensus statement identified several items for appropriate intraoperative photo-documentation in Crohn's disease surgery, to be used as an adjunct to accurate annotation of intraoperative findings and procedures.

Abstract
BACKGROUND & AIMS There are limited data on outcomes of biologic therapy in Hispanic patients with inflammatory bowel diseases (IBDs). We compared risk of hospitalization, surgery, and serious infections in Hispanic vs non-Hispanic patients with IBD in a multicenter, electronic health record-based cohort of biologic-treated patients. METHODS We identified adult patients with IBD who were new users of biologic agents (tumor necrosis factor α [TNF-α] antagonists, ustekinumab, vedolizumab) from 5 academic institutions in California between 2010 and 2017. We compared the risk of all-cause hospitalization, IBD-related surgery, and serious infections in Hispanic vs non-Hispanic patients using 1:4 propensity score matching and survival analysis. RESULTS We compared 240 Hispanic patients (53% male; 45% with ulcerative colitis; 73% TNF-α antagonist-treated; 20% with prior biologic exposure) with 960 non-Hispanic patients (51% male; 44% with ulcerative colitis; 67% TNF-α antagonist-treated; 27% with prior biologic exposure). After propensity score matching, Hispanic patients were younger (37 ± 15 vs 40 ± 16 y; P = .02) and had a higher burden of comorbidities (Elixhauser index, >0; 37% vs 26%; P < .01), without any differences in patterns of medication use, burden of inflammation, and hospitalizations. Within 1 year of biologic initiation, Hispanic patients had higher rates of hospitalizations (31% vs 23%; adjusted hazard ratio [aHR], 1.32; 95% CI, 1.01-1.74) and IBD-related surgery (7.1% vs 4.6%; aHR, 2.00; 95% CI, 1.07-3.72), with a trend toward higher risk of serious infections (8.8% vs 4.9%; aHR, 1.74; 95% CI, 0.99-3.05). CONCLUSIONS In a multicenter, propensity score-matched cohort of biologic-treated patients with IBD, Hispanic patients experienced higher rates of hospitalization, surgery, and serious infections. Future studies are needed to investigate the biological, social, and environmental drivers of these differences.

Abstract
INTRODUCTION Obesity is variably associated with treatment response in biologic-treated patients with inflammatory bowel diseases (IBD). We evaluated the association between obesity and risk of hospitalization, surgery, or serious infections in patients with IBD in new users of biologic agents in a large, multicenter, electronic health record (EHR)-based cohort (CA-IBD). METHODS We created an EHR-based cohort of adult patients with IBD who were new users of biologic agents (tumor necrosis factor [TNF-α] antagonists, ustekinumab, and vedolizumab) between January 1, 2010, and June 30, 2017, from 5 health systems in California. Patients were classified as those with normal body mass index (BMI), overweight, or obese based on the World Health Organization classification. We compared the risk of all-cause hospitalization, IBD-related surgery, or serious infections among patients with obesity vs those overweight vs those with normal BMI, using Cox proportional hazard analyses, adjusting for baseline demographic, disease, and treatment characteristics. RESULTS Of 3,038 biologic-treated patients with IBD (69% with Crohn's disease and 76% on TNF-α antagonists), 28.2% (n = 858) were overweight, and 13.7% (n = 416) were obese. On a follow-up after biologic initiation, obesity was not associated with an increased risk of hospitalization (adjusted hazard ratio [aHR] vs normal BMI, 0.90; [95% confidence interval, 0.72-1.13]); IBD-related surgery (aHR, 0.62 [0.31-1.22]); or serious infection (aHR, 1.11 [0.73-1.71]). Similar results were observed on stratified analysis by disease phenotype (Crohn's disease vs ulcerative colitis) and index biologic therapy (TNF-α antagonists vs non-TNF-α antagonists). DISCUSSION In a multicenter, EHR-based cohort of biologic-treated patients with IBD, obesity was not associated with hospitalization, surgery, or serious infections. Further studies examining the effect of visceral obesity on patient-reported and endoscopic outcomes are needed.

Abstract
BACKGROUND & AIMS Whether preoperative treatment of inflammatory bowel disease (IBD) with tumor necrosis factor inhibitors (TNFis) increases the risk of postoperative infectious complications remains controversial. The primary aim of this study was to determine whether preoperative exposure to TNFis is an independent risk factor for postoperative infectious complications within 30 days of surgery. METHODS We conducted a multicenter prospective observational study of patients with IBD undergoing intra-abdominal surgery across 17 sites from the Crohn's & Colitis Foundation Clinical Research Alliance. Infectious complications were categorized as surgical site infections (SSIs) or non-SSIs. Current TNFi exposure was defined as use within 12 weeks of surgery, and serum was collected for drug-level analyses. Multivariable models for occurrence of the primary outcome, any infection, or SSI were adjusted by predefined covariates (age, sex, preoperative steroid use, and disease type), baseline variables significantly associated (P < .05) with any infection or SSI separately, and TNFi exposure status. Exploratory models used TNFi exposure based on serum drug concentration. RESULTS A total of 947 patients were enrolled from September 2014 through June 2017. Current TNFi exposure was reported by 382 patients. Any infection (18.1% vs 20.2%, P = .469) and SSI (12.0% vs 12.6%, P = .889) rates were similar in patients currently exposed to TNFis and those unexposed. In multivariable analysis, current TNFi exposure was not associated with any infection (odds ratio, 1.050; 95% confidence interval, 0.716-1.535) or SSI (odds ratio, 1.249; 95% confidence interval, 0.793-1.960). Detectable TNFi drug concentration was not associated with any infection or SSI. CONCLUSIONS Preoperative TNFi exposure was not associated with postoperative infectious complications in a large prospective multicenter cohort.

Abstract
BACKGROUND Total proctocolectomy with ileal pouch-anal anastomosis has become the standard procedure for patients with medically refractory ulcerative colitis, although a subset will develop de novo Crohn's disease. OBJECTIVE In this study, we investigated the association of preoperative C-reactive protein levels with the development of de novo Crohn's disease after ileal pouch-anal anastomosis. DESIGN A prospectively maintained database of patients undergoing ileal pouch-anal anastomosis was reviewed. PATIENTS Preoperative C-reactive protein levels were compared between patients who developed de novo Crohn's disease and those who did not. De novo Crohn's disease was defined as small-bowel inflammation proximal to the ileal pouch or perianal disease identified more than 3 months after ileostomy closure. To minimize the heterogeneity of the timing of preoperative C-reactive protein measurement and the severity of ulcerative colitis, only hospitalized patients who had proctocolectomy for severe ulcerative colitis were included in the study. MAIN OUTCOME MEASURES Development of de novo Crohn's disease was analyzed. RESULTS Of 105 patients, 23 (22%) developed de novo Crohn's disease. Having C-reactive protein in the third tertile significantly increased the risk of developing de novo Crohn's disease (HR 3.44, 95% CI 1.10- 10.70, p = 0.03) compared to in the first tertile. In a multivariable model, a C-reactive protein in the third or second tertile vs the first tertile and younger age was associated with the development of de novo Crohn's disease. LIMITATIONS Limited to only hospitalized patients with severe ulcerative colitis. CONCLUSIONS In hospitalized patients undergoing ileal pouch-anal anastomosis for medically refractory ulcerative colitis, higher preoperative C-reactive protein levels appear to increase the risk of developing de novo Crohn's disease.

En un modelo multivariable, una proteína C reactiva en el tercer o segundo tercil frente al primer tercil y una edad más joven se asoció con el desarrollo de la enfermedad de Crohn de novo.LIMITACIONES:Limitado solo a pacientes hospitalizados con colitis ulcerativa grave.CONCLUSIONES:En pacientes hospitalizados sometidos a anastomosis bolsa ileal-anal por colitis ulcerativa refractaria al tratamiento médico, niveles más elevados de proteína C reactiva preoperatoria parecen aumentar el riesgo de desarrollar enfermedad de Crohn de novo.

Abstract
BACKGROUND Surgical management of anal fistulas in Crohn's disease (CD) is associated with high failure rates, and treatment options are limited due to ongoing proctitis, multiple tracts, and concern for incontinence and non-healing wounds. The aim of this study was to investigate the healing rate of ligation of the inters-sphincteric fistula tract (LIFT) for anal fistulas in Crohn's disease and identify prognostic factors for healing. METHODS This prospective analysis compared long-term healing rates of CD patients undergoing LIFT for anal fistulas. Consecutive patients with CD who underwent LIFT procedure at our institution, in the period from March 2012 to September 2019 were included. The main outcome was anal fistula healing rate. RESULTS The study cohort of 46 patients (mean age of 34.2 ± 13.0 years, 18 (40%) males). After a mean follow-up time of 33 ± 28 months, fistula healing was seen in 30 (65%) patients. A total of 8 patients were noted to have inter-sphincteric recurrence and 8 patients had trans-sphincteric recurrence. Smoking at the time of surgery was significantly associated with LIFT failure (HR 3.18, 95% CI 1.18-8.61, p = 0.02). Other factors, such as age, sex, race, disease duration and location, type of fistula history of proctitis, preoperatively use of biologics or a seton, and previous repair attempts, did not appear to influence LIFT healing. Although not statistically significant, there was a trend toward increase in failure among patients with active proctitis at the time of surgery (HR 1.97, 95% CI 0.71-5.42, p = 0.19). CONCLUSION Our increasing experience with LIFT for anal fistula in CD demonstrates a higher rate of healing (65%) than previously reported (48%). Smoking appears to negatively influence healing of LIFT in CD.

Abstract
The management of hospitalized patients with acute, severe ulcerative colitis involves close coordination among a multidisciplinary team. For patients not improving on intravenous corticosteroids, surgical consultation should be sought. The remaining hospital course requires frequent communications between the gastroenterologist managing the medical aspects of care, and the colorectal surgeon involved in planning for potential surgery, to optimize patient outcomes. This comanagement includes joint decision-making around the timing of surgery, minimizing medications associated with postoperative morbidity, addressing nutritional and psychosocial aspects of the patient's condition, and planning for a coordinated postoperative course. In this review, we highlight these aspects of care and the need for coordination and communication between gastroenterologists and surgeons in the management of acute severe colitis.

Abstract
AIM Ileocolic resection (ICR) is the most commonly performed operation in Crohn's disease (CD) patients. The surgical report is a vital tool for accessing information to gauge a patient's long-term prognosis and guide treatment decisions. Dictated narrative reports are the traditional method for surgical documentation but often lack essential information. The objective was to assess the quality of operation note in CD patients undergoing ICR. METHOD This was a multi-institutional retrospective cohort collaborative study involving four tertiary inflammatory bowel disease referral centres in the USA and Canada. The patients were consecutive CD patients undergoing ICR between 2014 and 2020. There were no interventions. The main outcome measures were the variability and frequency of 28 critical items in the operation note. RESULTS An analysis of 400 consecutive operation reports in four institutions (n = 100/institution) revealed significant variability in almost all variables. The initial surgical approach and wound protector use were the most consistently or frequently reported across all inflammatory bowel disease centres. The limitation was that this was a retrospective cohort study with inevitable selection bias. CONCLUSIONS This study highlights the need for synoptic reporting in CD patients undergoing ICR.

Abstract
BACKGROUND Vedolizumab has been proposed to lead to fewer postoperative complications because of its gut specificity. Studies, however, suggest an increased risk of surgical site infections, yet the data are conflicting. OBJECTIVE This study aimed to assess the effect of vedolizumab drug levels on postoperative outcomes in patients undergoing major abdominal surgery for IBD. DESIGN This was a retrospective study of a prospectively maintained database. SETTING Patients were operated on by a single surgeon at an academic medical center. PATIENTS A total of 72 patients with IBD undergoing major abdominal surgery were included. INTERVENTIONS Patients were exposed preoperatively to vedolizumab. MAIN OUTCOME MEASURES The primary outcome measured was the postoperative morbidity in patients who had IBD with detectable vs undetectable vedolizumab levels. RESULTS A total of 72 patients were included in the study. Thirty-eight patients had detectable vedolizumab levels (>1.6 μg/mL), and 34 had undetectable vedolizumab levels. The overall rate of complications was 39%, and ileus was the most common complication. There were no significant differences in clinical variables between the detectable and undetectable vedolizumab level patient groups except for the time between the last dose and surgery (p < 0.01). There were 42 patients in the ulcerative colitis cohort; 48% had an undetectable vedolizumab level and 52% had a detectable vedolizumab level. There were no differences in any postoperative morbidity between ulcerative colitis groups. The Crohn's cohort had 27 patients; 48% had an undetectable vedolizumab levels and 52% had a detectable vedolizumab level. There was a significantly lower incidence of postoperative ileus in patients who had Crohn's disease with detectable vedolizumab levels compared with patients with an undetectable vedolizumab level (p < 0.04). LIMITATIONS Limitations include a low overall patient population and a high rate of stoma formation. CONCLUSIONS Serum vedolizumab levels do not influence postoperative morbidity in IBD. Vedolizumab may reduce the incidence of postoperative ileus in patients with Crohn's disease. See Video Abstract at http://links.lww.com/DCR/B574.

Treinta y ocho pacientes tuvieron niveles detectables de vedolizumab (> 1,6 mcg / ml) y 34 con niveles no detectables de vedolizumab. La tasa global de complicaciones fue del 39% y el íleo fue la complicación más común. No hubo diferencias significativas en las variables clínicas entre los grupos de pacientes con niveles detectables y no detectables de vedolizumab, excepto por el intervalo de tiempo entre la última dosis y la cirugía (p <.01). La cohorte de colitis ulcerosa tuvo 42 pacientes, el 48% con un nivel no detectable de vedolizumab y el 52% un nivel detectable de vedolizumab. No hubo diferencias en ninguna morbilidad postoperatoria entre los grupos de colitis ulcerosa. La cohorte de Crohn tuvo 27 pacientes, 48% con niveles no detectables de vedolizumab y el 52% con niveles detectables de vedolizumab. Hubo una incidencia significativamente menor de íleo postoperatorio en pacientes de Crohn con niveles detectables de vedolizumab, comparados con los pacientes con un nivel no detectable de vedolizumab (p <0,04).LIMITACIONES:Las limitaciones incluyen una baja población general de pacientes y una alta tasa de formación de estomas.CONCLUSIONES:Los niveles séricos de vedolizumab no influyen en la morbilidad postoperatoria de la enfermedad inflamatoria intestinal. Vedolizumab puede reducir la incidencia de íleo postoperatorio en pacientes de Crohn. Consulte Video Resumen en http://links.lww.com/DCR/B574.

Abstract
BACKGROUND AND AIMS The host receptor for severe acute respiratory syndrome coronavirus 2, angiotensin-converting enzyme 2 (ACE2), is highly expressed in small bowel (SB). Our aim was to identify factors influencing intestinal ACE2 expression in Crohn's disease (CD), ulcerative colitis (UC), and non-inflammatory bowel disease (IBD) controls. METHODS Using bulk RNA sequencing or microarray transcriptomics from tissue samples (4 SB and 2 colonic cohorts; n = 495; n = 387 UC; n = 94 non-IBD), we analyzed the relationship between ACE2 with demographics and disease activity and prognosis. We examined the outcome of anti-tumor necrosis factor and anti-interleukin-12/interleukin-23 treatment on SB and colonic ACE2 expression in 3 clinical trials. Univariate and multivariate regression models were fitted. RESULTS ACE2 levels were consistently reduced in SB CD and elevated in colonic UC compared with non-IBD controls. Elevated SB ACE2 was also associated with demographic features (age and elevated body mass index) associated with poor coronavirus disease 2019 outcomes. Within CD, SB ACE2 was reduced in patients subsequently developing complicated disease. Within UC, colonic ACE2 was elevated in active disease and in patients subsequently requiring anti-tumor necrosis factor rescue therapy. SB and colonic ACE2 expression in active CD and UC were restored by anti-cytokine therapy, most notably in responders. CONCLUSIONS Reduced SB but elevated colonic ACE2 levels in IBD are associated with inflammation and severe disease, but normalized after anti-cytokine therapy, suggesting compartmentalization of ACE2-related biology in SB and colonic inflammation. The restoration of ACE2 expression with anti-cytokine therapy might be important in the context of severe acute respiratory syndrome coronavirus 2 infection and potentially explain reports of reduced morbidity from coronavirus disease 2019 in IBD patients treated with anti-cytokines.

Abstract
BACKGROUND AND AIMS Infliximab rescue therapy is effective in patients with corticosteroid refractory acute severe ulcerative colitis, but predictors of response remain poorly understood. We aimed to identify predictors of colectomy in this high-risk patient population. METHODS Patients hospitalized with acute severe ulcerative colitis who received infliximab after failing intravenous corticosteroid therapy between July 2012 and June 2017 were retrospectively identified. Stepwise regression with backward elimination was used to identify predictors of colectomy at 90 days and 1 year. Ninety-day and 1-year colectomy rates were compared between the patients who received 5 mg/kg and 10 mg/kg IFX rescue dose. RESULTS Sixty-three patients met the eligibility criteria. Twenty-nine patients received 5 mg/kg, and 34 received 10 mg/kg infliximab dose. Serum albumin on admission (OR 0.10; p = 0.04) and band neutrophil percentage at the time of infliximab administration (OR 1.21; p = 0.02) were independent predictors of 90-day colectomy. A combination of serum albumin ≤ 2.5 g/dl and band neutrophil count ≥ 13% had a 100% positive predictive value for 90-day colectomy. Unadjusted 90-day and 1-year colectomy rates were similar in the 5 mg/kg and 10 mg/kg infliximab groups. After adjusting for confounding factors, 10 mg/kg infliximab dose was potentially protective for 90-day (OR 0.07; p = 0.06) but not for 1-year colectomy (OR 0.19; p = 0.16). CONCLUSIONS Bandemia and low serum albumin are independent predictors of failure of infliximab rescue therapy in acute severe ulcerative colitis. Serum albumin ≤ 2.5 g/dl and band neutrophil count ≥ 13% had a 100% positive predictive value for 90-day colectomy.

Abstract
Up to 80% of Crohn's disease (CD) patients require surgery. Fecal diversion is used selectively in CD proctocolitis refractory to medical treatment or advanced perianal disease. This study examines associations between clinical features in predicting clinical response (CR) to fecal diversion in CD. Charts of CD patients undergoing fecal diversion for medically refractory disease or perianal disease were reviewed. Clinical response was assessed focusing on improvements in urgency, abdominal and perineal pain, decreased anal fistula drainage, and weight gain. Univariate binary logistic regression and multivariate forward-stepwise modeling analysis were used to determine associations with CR. The study cohort comprised 79 patients. After a median follow-up of 36 (3-192) months, 40 (51%) patients achieved a CR. Binary logistic regression analysis revealed both age at diagnosis (hazard ratio [HR] 1.05; confidence interval [CI] 1.01-1.09; P = .007) and disease duration (HR .91; CI .86-.96; P = .001) to be significantly associated with CR. Later age of onset (HR 1.05; CI 1.01-1.10; P = .002) and shorter disease duration (HR .91; CI .86-.97; P = .02) remained significant on multivariate analysis. This largest reported series of fecal diversion for refractory CD in the biologic drug era revealed that young age at diagnosis and long disease duration are associated with a lower CR.

Abstract
A mysterious feature of Crohn's disease (CD) is the extra-intestinal manifestation of "creeping fat" (CrF), defined as expansion of mesenteric adipose tissue around the inflamed and fibrotic intestine. In the current study, we explore whether microbial translocation in CD serves as a central cue for CrF development. We discovered a subset of mucosal-associated gut bacteria that consistently translocated and remained viable in CrF in CD ileal surgical resections, and identified Clostridium innocuum as a signature of this consortium with strain variation between mucosal and adipose isolates, suggesting preference for lipid-rich environments. Single-cell RNA sequencing characterized CrF as both pro-fibrotic and pro-adipogenic with a rich milieu of activated immune cells responding to microbial stimuli, which we confirm in gnotobiotic mice colonized with C. innocuum. Ex vivo validation of expression patterns suggests C. innocuum stimulates tissue remodeling via M2 macrophages, leading to an adipose tissue barrier that serves to prevent systemic dissemination of bacteria.

Abstract
Definitive draining seton (DDS) alone is an accepted treatment for complex refractory anal fistulas in Crohn’s disease (CD). We evaluated the long-term success of DDS in CD patients. DDS was defined as draining seton placed definitively for at least 12 months. Primary end point was clinical response (CR) defined as a lack of induration, pain, swelling, abscess recurrence, or unintended dislodgement. The study cohort of 23 patients had a median age of 29 (range; 9-61) years and included 14 males (61%). Reasons for DDS included anal stenosis (n = 9; 39%), active proctitis (n = 9; 39%), and/or anal canal ulceration (n = 9; 39%). Median number of setons was 2 (range; 1-6) and 65% had multiple fistula tracts. Almost all patients (n = 22; 96%) were on a biologic postoperatively. At 12-month follow-up, only 39% (n = 9) had a CR. The remaining 14 patients failed due to new abscess formation (n = 6; 26%), new fistula formation (n = 6; 26%), and seton dislodgement (n = 2; 9%). Six (26%) patients required fecal diversion. No patients required proctectomy. DDS for complex CD fistula results in a mediocre CR with many patients developing recurrent abscess/fistula or requiring diversion despite biologic therapy.

Abstract
BACKGROUND Multimodal analgesia protocols are becoming a common part of enhanced recovery pathways after colorectal surgery. However, few protocols include a robust intraoperative component in addition to pre-operative and post-operative analgesics. METHOD A prospective cohort study was performed in an urban teaching hospital in patients undergoing minimally invasive colorectal surgery before and after implementation of a multimodal analgesia protocol consisting of pre-operative (gabapentin, acetaminophen, celecoxib), intraoperative (lidocaine and magnesium infusions, ketorolac, transversus abdominis plane block), and post-operative (gabapentin, acetaminophen, celecoxib) opioid-sparing elements. The main outcome measure was use of morphine equivalents in the first 24-h post-operative period. RESULTS The study cohort (n = 71) included 41 patients before and 30 patients after implementation of a multimodal analgesia protocol. Mean age of the entire study cohort was 47 ± 19.7 years and 46% were male. Patients undergoing surgery post-multimodal analgesia vs. pre-multimodal analgesia had significantly lower use of IV morphine equivalents in first 24-h post-operative period (5.8 ± 6.4 mg vs. 22.8 ± 21.3 mg; p = 0.005) and first 48-h post-operative period (7.6 ± 9.4 mg vs. 42 ± 52.9 mg; p = 0.0008). This reduction in IV morphine equivalent use post-multimodal analgesia was coupled with improved pain scores in the post-operative period. Post-operative hospital length of stay, post-operative ileus, and overall complications were not significantly different between groups. CONCLUSIONS Multimodal analgesia incorporating pre-operative, intraoperative, and post-operative opioid-sparing agents is an effective method for reducing perioperative opioid utilization and pain after minimally invasive colorectal surgery.

Abstract
The management of IBD has been highly affected in the context of the COVID-19 pandemic, with restriction of hospitalisations and unprecedented redeployment of health care resources. Hospital admissions of IBD patients should be limited to reduce the risks of coronavirus transmission. However, delaying hospitalisation of IBD patients with severe or complicated disease may increase the risk of poor outcomes. Delaying surgery in some cases may increase the risk of disease progression, postoperative morbidity, and disease complications. IBD patients who are infected with SARS-CoV-2 may have a higher risk of poor outcomes than the general population, potentially related to concomitant medications, especially corticosteroids. There is no evidence today that IBD patients with COVID-19 have worse outcomes if they receive immunosuppressant medications including thiopurines, biologics, and novel small molecules. This article summarises recommendations by the international membership of IOIBD regarding hospitalisations of IBD patients, either for active or complicated IBD or for severe COVID-19, and for management of IBD patients according to SARS-CoV-2 infectious status.

Abstract
The primary aim of this study was to define predictors of computed tomography (CT)-guided percutaneous abscess drainage treatment failure in complicated diverticulitis. A 10-year retrospective analysis of inpatients seen in surgical consultation for diverticular abscess management subsequently referred for CT-guided percutaneous drainage (PD) was conducted. The clinical courses of patients undergoing a technically successful PD were categorized into three groups: 1) no colectomy; 2) elective colectomy; and 3) nonelective colectomy. Forty study patients were identified. Thirteen (33%) of the 40 patients required a nonelective colectomy, 20 patients (50%) underwent elective resection, and seven patients (18%) have been managed nonoperatively with no recurrent diverticulitis for a median of 46.8 months (range, 3.2 to 84.3 months). Forward logistic regression identified the presence of immunosuppression or renal insufficiency (creatinine 1.5 mg/dL or greater) as factors independently associated with failure of PD and need for non-elective colectomy. No clinical, laboratory, or radiologic variables were predictive of long-term nonoperative success. Although PD allows for the resolution of intra-abdominal sepsis for most cases of diverticulitis complicated by an abscess, a substantial proportion progress to nonelective colectomy, emphasizing the need for clinical vigilance in follow-up.

Abstract
The utility of opioid-sparing multimodal analgesia protocols (OSMMAPs) in opioid-tolerant (OT) patients is unknown. We sought to determine the impact of a standardized OSMMAP in OT versus opioid-naïve (ON) patients after major colorectal surgery. Consecutive patients undergoing surgery before (January 2015–March 2017) and after OSMMAP implementation (April 2017–March 2018) were identified from a single-institution prospective colorectal surgery registry. OT was defined by the presence of an opioid on the preadmission medication record. Opioid use (measured in oral morphine equivalents (OMEs)) and surgical outcomes were compared between OT and ON patients pre- and post-OSMMAP. The study cohort of 201 patients included 59 OT patients (25 pre- and 34 post-OSMMAP) and 142 ON controls (34 pre- and 108 post-OSMMAP). The median age was 47.5 years (IQR 32), and 50% were male. 185 patients (92%) had a laparoscopic/ robotic resection and 16 (8%) open. There were statistically significant reductions in OME required post-OSMMAP on each postoperative day (days 1 to 4) and cumulative OME for both OT and ON patients. The reduction in opioid requirements was significantly larger in OT than ON patients. We present the first study highlighting a larger opioid usage reduction in OT than in ON patients after OSMMAP implementation.

Abstract
Minimally invasive approaches to total abdominal colectomy (TAC) in ulcerative colitis (UC) patients include straight laparoscopy (SL), hand-assisted laparoscopic surgery (HALS), and robotics. In this study, short-term outcomes of patients undergoing SL and HALS TAC were compared. Prospectively collected data on UC patients undergoing TAC were tabulated. The study cohort included 36 (27%) patients in the SL group and 95 (73%) patients in the HALS group. The groups were comparable in terms of preoperative characteristics and demographics. The mean operative time was 151 (range, 73–225) minutes in the SL group versus 164 (range, 103–295) minutes in the HALS group ( P = 0.09). Total 48-hour IV morphine use was 30 (range, 0–186) mg in the SL group compared with 56 (0–275) mg in the HALS group ( P < 0.01). Although overall morbidity was comparable between the groups, Clavien-Dindo Class III complications did not occur in any of the SL group patients versus 11 (11%) of the HALS group patients ( P = 0.03). The postoperative length of stay was 3 (3–21) days in the SL group versus 5 (3–15) days in the HALS group ( P < 0.01). Compared with HALS, SL is associated with lower postoperative narcotic use and hospital length of stay in UC patients undergoing TAC.

Abstract
Angiotensin-Converting Enzyme 2 ( ACE2 ) has been identified as the host receptor for SARS-coronavirus 2 (SARS-CoV-2) which has infected millions world-wide and likely caused hundreds of thousands of deaths. Utilizing transcriptomic data from four cohorts taken from Crohn's disease (CD) and non-inflammatory bowel disease (IBD) subjects, we observed evidence of increased ACE2 mRNA in ileum with demographic features that have been associated with poor outcomes in COVID-19 including age and raised BMI. ACE2 was downregulated in CD compared to controls in independent cohorts. Within CD, ACE2 expression was reduced in inflamed ileal tissue and also remarkably, from uninvolved tissue in patients with a worse prognosis in both adult and pediatric cohorts. In active CD, small bowel ACE2 expression was restored by anti-TNF therapy particularly in anti-TNF responders. Collectively our data suggest that ACE2 downregulation is associated with inflammation and worse outcomes in CD.

Abstract
Background Although biologic agents have revolutionized the medical management of severe ulcerative colitis (UC), there is considerable controversy regarding adverse effects of vedolizumab on surgical outcomes. We evaluated 30-day postoperative morbidity in UC patients undergoing abdominal colectomy (AC) treated with vedolizumab before surgery. Methods From 2007 to 2017, 285 patients were enrolled in prospectively maintained database evaluating the role of clinical, serologic markers with clinical phenotypes in UC. The patients treated with vedolizumab within 12 weeks of AC was queried, then matched 1:3:3 into 3 preoperative treatment groups based on age, gender and surgical treatment of UC; ileal pouch-anal anastomosis (IPAA) with ileostomy vs total colectomy with end stoma: a) vedolizumab (n = 25); b) anti-tumor necrosis factor (anti-TNF) (n = 74); and c) no biologics (n = 54). Thirty-day postoperative complications among patient groups were compared. Results The 3 patient groups were well-matched in other characteristics including disease duration, disease extent, medication history and preoperative serological data. There were no significant differences in the overall incidence of postoperative complications among patients treated preoperatively with vedolizumab, anti-TNFs, or no biologics (44% vs. 45% vs. 37%; p = 0.67). Although there was no significant difference between patient cohorts in infectious complications (p = 0.20), postoperative ileus (POI) was significantly more common among the vedolizumab group (n = 9; 36%) compared to anti-TNF (n = 12; 16%) or no biologics (n = 5; 9%) (p = 0.01). Multivariable analysis showed that vedolizumab treatment prior to surgery was an independent risk factor for POI (OR: 5.16, 95% CI; 1.71–15.52; p = .004). Conclusion Although preoperative vedolizumab exposure did not influence the rate of overall 30-day postoperative complications, vedolizumab tends to increase incidence of POI.

Abstract
Minimally invasive approaches to total abdominal colectomy (TAC) in ulcerative colitis (UC) patients include straight laparoscopy (SL), hand-assisted laparoscopic surgery (HALS), and robotics. In this study, short-term outcomes of patients undergoing SL and HALS TAC were compared. Prospectively collected data on UC patients undergoing TAC were tabulated. The study cohort included 36 (27%) patients in the SL group and 95 (73%) patients in the HALS group. The groups were comparable in terms of preoperative characteristics and demographics. The mean operative time was 151 (range, 73-225) minutes in the SL group versus 164 (range, 103-295) minutes in the HALS group (P = 0.09). Total 48-hour IV morphine use was 30 (range, 0-186) mg in the SL group compared with 56 (0-275) mg in the HALS group (P < 0.01). Although overall morbidity was comparable between the groups, Clavien-Dindo Class III complications did not occur in any of the SL group patients versus 11 (11%) of the HALS group patients (P = 0.03).

Abstract
The utility of opioid-sparing multimodal analgesia protocols (OSMMAPs) in opioid-tolerant (OT) patients is unknown. We sought to determine the impact of a standardized OSMMAP in OT versus opioid-naïve (ON) patients after major colorectal surgery. Consecutive patients undergoing surgery before (January 2015-March 2017) and after OSMMAP implementation (April 2017-March 2018) were identified from a single-institution prospective colorectal surgery registry. OT was defined by the presence of an opioid on the preadmission medication record. Opioid use (measured in oral morphine equivalents (OMEs)) and surgical outcomes were compared between OT and ON patients pre- and post-OSMMAP. The study cohort of 201 patients included 59 OT patients (25 pre- and 34 post-OSMMAP) and 142 ON controls (34 pre- and 108 post-OSMMAP). The median age was 47.5 years (IQR 32), and 50% were male. 185 patients (92%) had a laparoscopic/robotic resection and 16 (8%) open. There were statistically significant reductions in OME required post-OSMMAP on each postoperative day (days 1 to 4) and cumulative OME for both OT and ON patients. The reduction in opioid requirements was significantly larger in OT than ON patients. We present the first study highlighting a larger opioid usage reduction in OT than in ON patients after OSMMAP implementation.

Abstract
Medical treatment remains the mainstay of perianal disease management for CD; however, aggressive surgical management should be considered for severe or recurrent disease. In all cases of perianal CD, medical and surgical treatments should be used in tandem by a multidisciplinary team. Significant development has been made in the treatment of Crohn's-related fistulas, particularly minimally invasive options with recent clinical trials showing success with mesenchymal stem cell applications. Inevitably, some patients with severe refractory disease may require fecal diversion or proctectomy. When considering reversal of a diverting or end ileostomy, cessation of proctitis is the most important factor.

Abstract
BACKGROUND AND AIMS Heterogeneity in Crohn's disease [CD] provides a challenge for the development of effective therapies. Our goal was to define a unique molecular signature for severe, refractory CD to enable precision therapy approaches to disease treatment and to facilitate earlier intervention in complicated disease. METHODS We analysed clinical metadata, genetics, and transcriptomics from uninvolved ileal tissue from CD patients who underwent a single small bowel resection. We determined transcriptional risk scores, cellular signatures, and mechanistic pathways that define patient subsets in refractory CD. RESULTS Within refractory CD, we found three CD patient subgroups [CD1, CD2, and CD3]. Compared with CD1, CD3 was enriched for subjects with increased disease recurrence after first surgery [OR = 6.78, p = 0.04], enhanced occurrence of second surgery [OR = 5.07, p = 0.016], and presence of perianal CD [OR = 3.61, p = 0.036]. The proportion of patients with recurrence-free survival was smaller in CD3 than in CD1 (p = 0.02, median survival time [months] in CD1 = 10 and CD3 = 6). Overlaying differential gene expression between CD1 and CD3 on CD subgroup-associated genetic polymorphisms identified 174 genes representing both genetic and biological differences between the CD subgroups. Pathway analyses using this unique gene signature indicated eukaryotic initiation factor 2 [eIF2] and cyclic adenosine monophosphate [cAMP] signalling to be dominant pathways associated with CD3. Furthermore, the severe, refractory subset, CD3, was associated with a higher transcriptional risk score and enriched with eosinophil and natural killer T [NKT] cell gene signatures. CONCLUSION We characterized a subset of severe, refractory CD patients who may need more aggressive treatment after first resection and who are likely to benefit from targeted therapy based on their genotype and tissue gene expression signature.

Abstract
Traditionally, surgical interventions for colonic Crohn's disease (CD) have been limited to total abdominal colectomy and ileorectal anastomosis, or total proctocolectomy with end ileostomy if there is rectal involvement. However, improved understandings of the biology of CD, as well as the development of biologic therapies, have enabled more limited resections. Here, we review the indications for, and limitations of, specific procedures aiming to preserve intestinal continuity in colonic CD.

Abstract
The ideal incision for specimen extraction during laparoscopic colorectal surgery is controversial. The objective of this study was to compare incision types (Pfannenstiel, periumbilical, lower midline, and right upper quadrant transverse) with regard to postoperative scar appearance, symptoms, preference, and satisfaction. This study is a retrospective survey review performed in an urban teaching hospital. The study participants were patients undergoing multiport laparoscopic colorectal surgery. Two web-based questionnaires, the Patient Scar Assessment Questionnaire and Photo-Series Questionnaire, were used to assess study parameters. The main outcome measures were incision symptoms and cosmetic satisfaction. The 112 study patients included 54 patients with a Pfannenstiel incision (Group P) and 58 patients with an alternate incision (Group A). Of the 58 patients in Group A, 19 (33%) had a periumbilical incision, 10 (17%) a lower midline incision, and 29 (50%) a right upper quadrant transverse incision. Although Groups P and A were comparable in all five subscales of the Patient Scar Assessment Questionnaire, more Group P participants (n = 12; 22%) said their incision felt "fairly numb" than Group A participants (n = 2; 3%) (P = 0.008). There was no significant difference between study groups in all Photo-Series Questionnaire domains; however, after comparing patients' own incisions with photographs of various alternative incisions, 36 (62%) Group A patients would choose an alternative incision compared with only 11 (19%) Group P patients (P = 0.001). Selection bias, recall bias, external validity, and variability of scar lengths were the limitations of the study. It was concluded that although a Pfannenstiel incision seems to be the optimal cosmetic choice, it is associated with a higher incidence of wound numbness than alternate extraction incisions.

Abstract
BACKGROUND Transversus abdominis plane block may improve analgesia after colorectal surgery; however, techniques remain unstandardized and results are conflicting. OBJECTIVE The purpose of this study was to compare laparoscopic and ultrasound-guided transversus abdominis plane block with no block in minimally invasive colorectal surgery. DESIGN This was a randomized controlled trial. SETTINGS The study was conducted at an urban teaching hospital. PATIENTS Patients undergoing laparoscopic colorectal surgery were included. INTERVENTIONS The intervention included 2:2:1 randomization to laparoscopic, ultrasound-guided, or no transversus abdominis plane block. MAIN OUTCOME MEASURES Morphine use in the first 24 hours after surgery was measured. RESULTS The study cohort included 107 patients randomly assigned to laparoscopic (n = 41), ultrasound-guided (n = 45), or no transversus abdominis plane block (n = 21). Mean age was 50.4 years (SD ± 18 y), and 50 patients (47%) were men. Laparoscopic transversus abdominis plane block was superior to ultrasound-guided (p = 0.007) and no transversus abdominis plane block (p = 0.007), with median (interquartile range) total morphine used in the first 24 hours postoperatively of 17.6 mg (6.6-33.9 mg), 34.0 mg (16.4-44.4 mg), and 31.6 mg (18.4-44.4 mg). At 48 hours, laparoscopic transversus abdominis plane block remained superior to ultrasound-guided (p = 0.03) and no transversus abdominis plane block (p = 0.007) with median (interquartile range) total morphine used at 48 hours postoperatively of 26.8 mg (15.5-45.8 mg), 44.0 mg (27.6-70.0 mg), and 60.8 mg (34.8-78.8 mg). Mean hospital stay was 5.1 ± 3.1 days without any intergroup differences. Overall complications were similar between groups. LIMITATIONS Treatment teams were not blinded and there was operator dependence of techniques and variable timing of the blocks. CONCLUSIONS Laparoscopic transversus abdominis plane block is superior to ultrasound-guided and no transversus abdominis plane block in achieving pain control and minimizing opioid use in the first 24 hours after colorectal surgery. A large, multicenter, randomized trial is needed to confirm our findings. See Video Abstract at http://links.lww.com/DCR/A822.

Abstract
AIM Short-term morbidity and long-term functional outcome of patients with an ileal pouch-anal anastomosis (IPAA) exposed to pelvic external beam radiation therapy (EBRT) remains unknown. We report the largest series to date regarding the effects of pelvic EBRT on: (i) 30-day postoperative outcomes; and (ii) long-term functional outcome following IPAA. METHOD A retrospective chart review was conducted of patients who received EBRT before or after IPAA between 1980 and 2017 across three international inflammatory bowel disease referral centres. RESULTS Nineteen patients were included. Indications for EBRT were rectal adenocarcinoma (n = 13), prostate adenocarcinoma (n = 4) or anal squamous cell carcinoma (ASCC) (n = 2). EBRT was given prior to IPAA in 12 (63%) patients and after IPAA in seven (37%). In EBRT before IPAA, patients had a median of 5 (range: 4-8) daytime bowel movements, 1 (range: 0-5) night-time bowel movement, no daytime incontinence, and only one patient used pads at a median follow up of 25 (range: 11-163) months; one patient underwent pouch excision 15 months after IPAA. In EBRT after IPAA, patients reported a median of 8 (range: 5-10) daytime and 2 (range: 0-5) night-time bowel movements, 80% had either daytime or night-time incontinence and 80% used pads at a median follow up of 90 (range: 25-315) months. CONCLUSION Pelvic EBRT administered prior to IPAA is associated with acceptable long-term function outcome. However, when pelvic EBRT is given to an IPAA in situ, most patients experience poor long-term pouch function without pouch failure.

Abstract
Open resection remains the standard of care in the surgical management of rectal cancer with recent studies unable to prove noninferiority of laparoscopic resection. Few studies directly compare robotic versus open techniques. This is a retrospective chart review of all consecutive patients undergoing robotic or open rectal cancer resection during a three-year period. The primary endpoint was a composite of complete mesorectal excision, circumferential resection margin <1 mm, and distal resection margin <1 mm. The study cohort included 64 patients undergoing robotic (n = 28) or open (n = 36) resection. Successful surgical resection was similar between the robotic (75%) and open (76%) approaches. Robotic resection was associated with significantly lower blood loss ( P = 0.02) and significantly longer operative times ( P = 0.009) compared with open resection. Length of hospital stay and complications were similar between groups. Both male gender ( P = 0.03) and shorter tumor distance from the anal verge ( P = 0.01) were predictors for unsuccessful surgical resection in open, but not robotic, surgery. Pathologic outcomes are similar between robotic and open rectal cancer resection, even early in the learning curve. Tumor distance from the anal verge complicates open total mesorectal excision; however, robotic surgery is less impacted. Robotic resection may be a promising minimally invasive approach for rectal cancer resection.

Abstract
Early postoperative feeding is the standard of care after colorectal surgery and is associated with improved outcomes. A controlled study performed at our center demonstrated faster bowel function recovery and shorter hospital stay without an increase in postoperative morbidity for a solid versus clear-liquid diet on postoperative day (POD) 1 after colorectal surgery. The present study aims to evaluate the impact of these findings on the practice of diet advancement by board-certified general surgeons (GS) and colorectal surgeons (CRS) at an urban teaching hospital. Patients undergoing elective colorectal surgery were prospectively evaluated. Data were compared with that of a study cohort that underwent elective colorectal surgery reported in 2012. Early postoperative feeding in the more recent cohort statistically increased for all cases on POD 0 and POD 1. Diet advancement over time revealed significant changes in early feeding on POD 0 for patients operated on by CRS (0% vs 83%; P < 0.0001) but not GS (13% vs 13%; P = 1). Patients operated on by either CRS or GS and offered early feeding on POD 1 did not significantly differ between time periods. Despite well-documented evidence of the advantages of early feeding, GS, but not CRS, remain reluctant to administer early diets to patients after colorectal surgery.

Abstract
BACKGROUND Ustekinumab, a monoclonal antibody targeting interleukins-12 and -23 is used to treat adults with Crohn's disease [CD]. We determined the 30-day postoperative infectious complication rate among CD patients who received ustekinumab within the 12 weeks prior to an abdominal operation as compared with patients who received anti-tumor necrosis factor [TNF] agents. METHODS A retrospective chart review of adults with CD who underwent an abdominal operation between January 1, 2015 and May 1, 2017 was performed across six sites. Surgical site infection [SSI] was defined as superficial skin and soft tissue infection, intra-abdominal abscess, anastomotic leak, and mucocutaneous separation of the stoma. RESULTS Forty-four patients received ustekinumab and 169 patients received anti-TNF therapy within the 12 weeks prior to surgery. The two groups were similar, except anti-TNF patients were more likely to have received combination therapy with an immunomodulator [P = 0.006]. There were no significant differences in postoperative SSI [13% in ustekinumab versus 20% in anti TNF-treated patients, p = 0.61] or hospital readmission rates [18% versus 10%, respectively, p = 0.14], but ustekinumab-treated patients had a higher rate of return to the operating room [16% versus 5%; P = 0.01]. There were no significant predictors identified on multivariable analysis. CONCLUSIONS Of the 44 patients with CD who received ustekinumab within the 12 weeks prior to a major abdominal operation, 13% experienced a 30-day postoperative SSI, not statistically different from the 20% found in the anti-TNF cohort. Ustekinumab treatment within 12 weeks of surgery does not appear to increase the risk of postoperative SSI above that of CD patients treated with anti-TNF medications.

Abstract
Many Crohn’s disease (CD) patients develop intestinal strictures, which are difficult to prevent and treat. Cationic steroid antimicrobial 13 (CSA13) shares cationic nature and antimicrobial function with antimicrobial peptide cathelicidin. As many functions of cathelicidin are mediated through formyl peptide receptor-like 1 (FPRL1), we hypothesize that CSA13 mediates anti-fibrogenic effects via FPRL1. Human intestinal biopsies were used in clinical data analysis. Chronic trinitrobenzene sulfonic acid (TNBS) colitis-associated intestinal fibrosis mouse model with the administration of CSA13 was used. Colonic FPRL1 mRNA expression was positively correlated with the histology scores of inflammatory bowel disease patients. In CD patients, colonic FPRL1 mRNA was positively correlated with intestinal stricture. CSA13 administration ameliorated intestinal fibrosis without influencing intestinal microbiota. Inhibition of FPRL1, but not suppression of intestinal microbiota, reversed these protective effects of CSA13. Metabolomic analysis indicated increased fecal mevalonate levels in the TNBS-treated mice, which were reduced by the CSA13 administration. CSA13 inhibited colonic HMG-CoA reductase activity in an FPRL1-dependent manner. Mevalonate reversed the anti-fibrogenic effect of CSA13. The increased colonic FPRL1 expression is associated with severe mucosal disease activity and intestinal stricture. CSA13 inhibits intestinal fibrosis via FPRL1-dependent modulation of HMG-CoA reductase pathway.

Abstract
The majority of colorectal cancers (CRC) harbor somatic mutations and epigenetic modifications in the tumor tissue, and some of these mutations can be detected in plasma as circulating tumor DNA (ctDNA). Precancerous colorectal lesions also contain many of these same mutations. This study examined plasma for ctDNA from patients undergoing a screening or diagnostic colonoscopy to determine the sensitivity and specificity of the ctDNA panel for detecting CRC and precancerous lesions. Two hundred patients without a history of nonskin cancer had blood drawn before a colonoscopy. Plasma ctDNA was measured with a 96 mutation panel for nine cancer driver genes. The ctDNA results were correlated with the findings at colonoscopy. Of the 200 patients, 176 (88%) had wild‐type DNA, 12 (6%) had mutations detected, and 12 (6%) had indeterminate results. Colonoscopy was normal in 80% of the patients and 20% were found to have polyps. No CRC was found in this study, precluding a determination of true‐positive rate for CRC detection. Our ctDNA panel was positive in 13.2% of patients with colonic polyps found at colonoscopy, while 4.7% of patients with normal colonoscopy also had ctDNA detected, which may represent ctDNA released from a benign process, an occult tumor, or an acquired somatic mutation from clonal hematopoiesis.
