Clinical Decision Making in Inflammatory Bowel Disease Mimics: Practice Management from Inflammatory Bowel Disease LIVE.

Background: Since 2009, inflammatory bowel disease (IBD) specialists have utilized "IBD LIVE," a weekly live video conference with a global audience, to discuss the multidisciplinary management of their most challenging cases. While most cases presented were confirmed IBD, a substantial number were diseases that mimic IBD. We have categorized all IBD LIVE cases and identified "IBD-mimics" with consequent clinical management implications. Methods: Cases have been recorded/archived since May 2018; we reviewed all 371 cases from May 2018-February 2023. IBD-mimics were analyzed/categorized according to their diagnostic and therapeutic workup. Results: Confirmed IBD cases made up 82.5% (306/371; 193 Crohn's disease, 107 ulcerative colitis, and 6 IBD-unclassified). Sixty-five (17.5%) cases were found to be mimics, most commonly medication-induced (n = 8) or vasculitis (n = 7). The evaluations that ultimately resulted in correct diagnosis included additional endoscopic biopsies (n = 13, 21%), surgical exploration/pathology (n = 10, 16.5%), biopsies from outside the GI tract (n = 10, 16.5%), genetic/laboratory testing (n = 8, 13%), extensive review of patient history (n = 8, 13%), imaging (n = 5, 8%), balloon enteroscopy (n = 5, 8%), and capsule endoscopy (n = 2, 3%). Twenty-five patients (25/65, 38%) were treated with biologics for presumed IBD, 5 of whom subsequently experienced adverse events requiring discontinuation of the biologic. Many patients were prescribed steroids, azathioprine, mercaptopurine, or methotrexate, and 3 were trialed on tofacitinib. Conclusions: The diverse presentation of IBD and IBD-mimics necessitates periodic consideration of the differential diagnosis, and reassessment of treatment in presumed IBD patients without appropriate clinical response. The substantial differences and often conflicting treatment approaches to IBD versus IBD-mimics directly impact the quality and cost of patient care.

Judicious Use of Ozanimod for Ulcerative Colitis and Multiple Sclerosis.

Clinical trials have demonstrated the efficacy of ozanimod, an oral sphingosine-1-phosphate receptor modulator, for the treatment of moderate-to-severe ulcerative colitis. Infrequently does an opportunity present itself to use one drug for two simultaneous disease states, proving especially beneficial in the case of this patient intolerant of numerous established therapies for ulcerative colitis. This case report describes the successful use of ozanimod for both ulcerative colitis and multiple sclerosis, achieving clinical remission in both diseases.

Far From Home: The Role of Travel Distance and Care Fragmentation in Surgical Outcomes for Inflammatory Bowel Disease.

Background: Fragmented care for inflammatory bowel disease (IBD) is known to correlate negatively with outcomes, but it is unclear which aspects of care fragmentation are relevant and potentially modifiable. Furthermore, there is little data on the relationship between travel distance and the benefits of integrated care models. Hypothesizing care coordination in the preoperative period may have a significant impact on surgical outcomes, we explored associations between integrated care, travel distance, and surgical outcomes. Methods: A single-center retrospective cohort study of patients undergoing index abdominal surgery was done to compare the rate of surgical complications with and without long travel distance and nonintegrated preoperative care. Multivariable logistic regression was used to identify factors independently associated with complications. Results: One hundred and fifty-seven patients were included. Complications were more common among patients with travel distance >75 miles (47.6% vs 27.4%, P = .012). Integrated preoperative care was not significant on bivariate (P = .381) or multivariable analysis but had a stronger association among patients with travel distance <75 miles (20.9% integrated vs 36.7%, P = .138). After adjustment, new ileostomy, open surgical approach, and distance >75 miles were independently associated with complications. Conclusions: Patients with longer travel distances to the hospital were twice as likely to have a surgical complication after adjusting for other risk factors. Without significant accommodations for remote patients, potential benefits of an integrated model for IBD care may be limited to patients who live close to the medical center. Future efforts addressing continuity of care should consider tactics to mitigate the impact of travel distance on outcomes.

Challenges in the Management of and Biologic Use in Incarcerated Patients With Inflammatory Bowel Disease.

Background: Therapy and management of inflammatory bowel disease (IBD) require commitment from both the provider and patient to ensure optimal disease management. Prior studies show vulnerable patient populations with chronic medical conditions and compromised access to health care, such as incarcerated patients, suffer as a result. After an extensive literature review, there are no studies outlining the unique challenges associated with managing prisoners with IBD. Methods: A detailed retrospective chart review of 3 incarcerated patients cared for at a tertiary referral center with an integrated patient-centered IBD medical home (PCMH) and a review of literature was performed. Results: All 3 patients were African American males in their 30s with severe disease phenotypes requiring biologic therapy. All patients had challenges with medication adherence and missed appointments related to inconsistent access to clinic. Two of the 3 cases depicted better patient-reported outcomes through frequent engagement with the PCMH. Conclusions: It is evident there are care gaps and opportunities to optimize care delivery for this vulnerable population. It is important to further study optimal care delivery techniques such as medication selection, though interstate variation in correctional services poses challenges. Efforts can be made to focus on regular and reliable access to medical care, especially for those who are chronically ill.

COVID-19 Pandemic Increased Anxiety Among Patients with Inflammatory Bowel Disease: A Patient Survey in a Tertiary Referral Center.

BACKGROUND: COVID-19 is the first global pandemic in more than 100 years, and at its onset, the effects were largely unknown. Immunocompromised patients, including IBD, were presumed to have higher risk. AIMS: We hypothesized patients with IBD would have higher-than-baseline anxiety, high perceived vulnerability and significant lifestyle impacts as a result of the pandemic. We sought to assess the impact of these changes on disease and management. METHODS: A cross-sectional study of patients with Crohn's disease, ulcerative colitis and IBD-unspecified was conducted. Patients were invited to participate by email in an IRB-approved brief, voluntary survey. Survey questions focused on disease characteristics, healthcare access and self-reported psychological well-being. RESULTS: Responses from 492 (CD = 337, UC = 141,IC = 14) patients were included in the analysis. The majority of patients with IBD had increased anxiety since the pandemic, which correlated with an increase in GI symptoms. This risk of symptoms was mitigated by communication with their provider. Many patients had lifestyle changes including requesting time off work due to perceived vulnerability and changes in eating habits. CONCLUSIONS: Our findings support an increase in illness-associated anxiety and perceived vulnerability among patients with IBD during the COVID-19 pandemic. Open communication with providers is important to maintain adequate control of disease and reduce symptoms of flares triggered by ongoing stress.

Towards Equitable Surgical Management of Inflammatory Bowel Disease: A Systematic Review of Disparities in Surgery for Inflammatory Bowel Disease.

BACKGROUND: Existing evidence for disparities in inflammatory bowel disease is fragmented and heterogenous. Underlying mechanisms for differences in outcomes based on race and socioeconomic status remain undefined. We performed a systematic review of the literature to examine disparities in surgery for inflammatory bowel disease in the United States. METHODS: Electronic databases were searched from 2000 through June 11, 2021, to identify studies addressing disparities in surgical treatment for adults with inflammatory bowel disease. Eligible English-language publications comparing the use or outcomes of surgery by racial/ethnic, socioeconomic, geographic, and/or institutional factors were included. Studies were grouped according to whether outcomes of surgery were reported or surgery itself was the relevant end point (utilization). Quality was assessed using the Newcastle-Ottawa Scale for observational studies. RESULTS: Forty-five studies were included. Twenty-four reported surgical outcomes and 21addressed utilization. Race/ethnicity was considered in 96% of studies, socioeconomic status in 44%, geographic factors in 27%, and hospital/surgeon factors in 22%. Although study populations and end points were heterogeneous, Black and Hispanic patients were less likely to undergo abdominal surgery when hospitalized; they were more likely to have a complication when they did have surgery. Differences based on race were correlated with socioeconomic factors but frequently remained significant after adjustments for insurance and baseline health. CONCLUSIONS: Surgical disparities based on sociologic and structural factors reflect unidentified differences in multidisciplinary disease management. A broad, multidimensional approach to disparities research with more granular and diverse data sources is needed to improve health care quality and equity for inflammatory bowel disease.

Existing evidence for disparities in inflammatory bowel disease management is fragmented. In reviewing the surgical literature, differences in outcomes by race and socioeconomic status reveal opportunities for improving equity while highlighting continued knowledge gaps in understanding disparities.

Endoscopic ultrasound-directed transgastric ERCP (EDGE): a systematic review describing the outcomes, adverse events, and knowledge gaps.

BACKGROUND : Endoscopic ultrasound-directed transgastric endoscopic retrograde cholangiopancreatography (EDGE) has emerged as a viable completely endoscopic method for performing pancreaticobiliary interventions in patients with Roux-en-Y gastric bypass anatomy. The aims of this systematic review were: (1) to describe the indications, outcomes, and complications of EDGE; and (2) to identify deficiencies in our knowledge of important technical approaches and clinical outcomes. METHODS : A systematic review was conducted via comprehensive searches of Medline, Scopus, CINAHL, and Cochrane to identify studies focusing on EDGE outcomes. Simple descriptive statistics were derived from case series only. Case reports were only included to qualitatively describe additional indications, techniques, and adverse events. RESULTS : The initial search identified 2143 abstracts. Nine case series and eight case reports were included. In the nine case series, 169 patients underwent EDGE. The technical success rate was 99 % (168 /169) for gastrogastrostomy/jejunogastrostomy creation and 98 % (166 /169) for subsequent ERCP. Minor adverse events specifically related to EDGE occurred in 18 % (31/169) and included intraprocedural stent migration/malposition (n = 27) and abdominal pain (n = 4). Moderate adverse events specific to EDGE occurred in 5 % (9/169): including bleeding (2 %), persistent fistula (1 %), and perforation (1 %). Severe adverse events occurred in one patient with a perforation requiring surgery. Deficiency in reporting on the clinical significance of adverse events was identified. CONCLUSION : Based on limited observational data, in expert hands, EDGE has a high rate of technical success and an acceptable rate of adverse events. As a novel procedure, many knowledge gaps need to be addressed to inform the design of meaningful comparative studies and guide informed consent.

Development of an automated ERCP Quality Report Card using structured data fields.

BACKGROUND AND AIMS: Measuring adherence to ERCP quality indicators (QIs) is confounded by variability in indications, maneuvers, and documentation styles. We hypothesized that incorporation of mandatory, structured data fields within reporting software would permit accurate measurement of QI adherence rates and facilitate generation of a provider ERCP report card. METHODS: At two referral centers, endoscopy documentation software was modified to generate provider alerts prior to finalizing the note. The alerts reminded the provider to document the following components in a standardized manner: indication, altered anatomy, prior interventions, and QIs deemed high priority by society consensus, study authors, or both. Adherence rates for each QI were calculated in aggregate and by provider via data extraction directly from the procedure documentation software. Medical records were reviewed manually to measure the accuracy of automated data extraction. Accuracy of automated measurement for each QI was calculated against results derived by manual review. RESULTS: During the 9-month study period, 1,376 ERCP procedures were completed by 8 providers. Manual medical record review confirmed high (98-100%) accuracy of automatic extraction of ERCP QIs from the endoscopy report, including cannulation rate of the native papilla and complete extraction of common bile duct stones. An ERCP report card was generated, allowing for individual comparison of adherence to ERCP QIs with colleagues at their institution and others. CONCLUSION: In this pilot study, use of mandatory, structured data fields within clinical ERCP reports permit the accurate measurement of high priority ERCP QIs and the subsequent generation of interval report cards.

Single-pass 1-needle actuation versus single-pass 3-needle actuation technique for EUS-guided liver biopsy sampling: a randomized prospective trial (with video).

BACKGROUND AND AIMS: Several reports have validated EUS-guided liver biopsy sampling (EUS-LB) as safe and effective. Nineteen-gauge EUS aspiration (FNA) or core (fine-needle biopsy [FNB]) needles are used, but different needle techniques can yield variable outcomes. Some data show that 1 pass (single liver puncture) with 1 actuation (1 to-and-fro needle movement) may be enough to obtain a satisfactory specimen. However, there has not been a head-to-head comparison of single versus multiple needle actuations for EUS-LB. METHODS: This was a prospective randomized trial of EUS-LB in 40 patients comparing tissue yields and adequacy using 1 pass, 1 actuation (1:1) versus 1 pass 3 actuations (1:3) of an FNB needle. The primary outcome was number of complete portal triads (CPTs). Secondary outcomes were length of the longest piece, aggregate specimen length, number of cores >9 mm, and adverse events (AEs). Computerized randomization determined selection (either 1:1 or 1:3 with fanning technique). Sample lengths were measured before pathologic processing. RESULTS: Both groups had similar demographics and indications for EUS-LB. All biopsy samples were adequate for pathologic interpretation. Compared with 1:1, biopsy sampling with 1:3 yielded more CPTs (mean [standard deviation], 17.25 [6.2] vs 24.5 [9.88]; P < .008) and longer aggregate specimen length (6.89 cm [1.86] vs 12.85 cm [4.02]; P < .001). AEs were not statistically different between the techniques. No severe AEs were noted. CONCLUSIONS: EUS-LB using the 1:3 technique produced longer liver cores with more CPTs than the 1:1 technique with an equivalent safety profile. Two needle passes are more likely to provide tissue adequacy according to the American Association for the Study of Liver Diseases guidelines. (Clinical trial registration number: UMIN 000040101.).

P068 Racial and Socioeconomic Disparities in Acute Care Utilization in a National Cohort of Veterans With IBD.

BACKGROUND: Hospitalizations for Black patients with inflammatory bowel disease (IBD) have increased in recent decades though our understanding of disease behavior in Black patients remains limited and concerns related to healthcare equity persist. Existing data are largely drawn from small case series at IBD referral centers or national registries lacking granular longitudinal outpatient data. Our aim was to determine whether there are racial or socioeconomic disparities in acute care utilization as measured by hospitalizations and emergency department (ED) visits within a large national cohort of IBD patients. METHODS: National Veterans Heath Administration (VHA) data were used to examine baseline disease characteristics and two years of utilization following an index outpatient gastroenterology visit for Crohn's disease (CD) or ulcerative colitis (UC) in 2017. To account for patients more likely to access care outside the VHA, we excluded those with less than four unique VHA encounters per year. We compared differences in comorbidity burden [Charlson comorbidity index, (CCI)], disease duration, surgical history and modifiable IBD severity risk factors (opioid use, tobacco use, biologic agent use, anemia, malnutrition) based on race and area deprivation index (ADI), a multidimensional marker for regional socioeconomic status (SES). Negative binomial regression was used to model demographic and clinical risk factors associated with hospitalization and ED visits. RESULTS: 19,442 patients (47.4% with CD and 52.6% with UC) were included: 14% Black, 5% Hispanic and 76% White. Compared to White patients, Black patients were younger, more likely to have anemia, perianal disease, and be in the bottom quartile of ADI; they were less likely to have a history of intestinal resection. IBD type, disease duration, CCI, and rates of tobacco use, opioid use, and malnutrition were not different between Black and White patients. On bivariate analysis, Black patients had increased mean and median ED visits compared to White patients (mean 4.48 vs 3.32; p < 0.001) though no differences were seen in hospitalizations (mean 0.96 vs 0.92; p=NS). On stepwise multivariable modeling, hospitalization and ED utilization were significantly higher among Black patients when controlling for age, sex, type of IBD, and disease duration [OR for hospitalization: 1.114 (95% CI: 1.046-1.199); OR for ED visit: 1.191 (95% CI: 1.125-1.261)]. After sequential adjustment for CCI and modifiable IBD severity risk factors, no differences in hospitalizations were seen between Black and White patients. In the full model for ED visits including adjustments for modifiable IBD severity risk factors (all significant), Black race was significantly associated with increased frequency of ED access [OR: 1.261 (95% CI: 1.19-1.336)], while ADI was not. CONCLUSION: In this analysis of a large national outpatient cohort of patients with IBD, we identified significant racial differences in IBD disease behavior, anemia and subsequent acute care utilization. Racial differences in hospitalization were not significant after controlling for modifiable IBD risk factors suggesting actionable targets to mitigate the observed disparities. However, Black race was independently associated with ED utilization even in a healthcare system where access to care is theoretically similar. Future studies should investigate factors underlying increased ED utilization among Black IBD patients in further detail.

P076 The Role of Dual Biologic Therapy in Inflammatory Bowel Disease.

BACKGROUND: As the prevalence of complex inflammatory bowel disease and extraintestinal manifestations continue to rise, more patients are requiring complex treatment regimens. In some cases, patients may require more than one biologic agent to target different areas in the inflammatory cascade. Although a body of data is emerging, there is currently no consensus on patient and agent selection for dual therapy or adverse outcomes of therapy. METHODS: A retrospective chart review of all patients receiving dual biologic therapy for IBD at a single tertiary care center was conducted. This was exempted by the IRB. Data regarding the patient and disease course, indication for dual biologic use, other concurrent therapies, infections and any adverse events was collected from the EMR. RESULTS: Ten patients (9 Crohn's Disease, 1 Ulcerative Colitis) were identified as receiving dual biologic therapy. The most common combination therapy was ustekinumab with vedolizumab (5) or an anti-TNF (4); one patient was receiving adalimumab with vedolizumab. Nine patients were also on an immunomodulator (6 methotrexate, 2 6-mercaptopurine, 1 azathioprine) and three required steroids in addition to dual biologic therapy. The majority (8) of the patients were started on dual biologic therapy due to refractory GI symptoms, the others were due to extraintestinal manifestations (EIMs) with psoriatic arthritis and ankylosing spondylitis. Nine patients had significant symptomatic improvement on dual biologic regimen and all six patients with follow-up endoscopy demonstrated improvement. Two patients developed infectious diarrhea (C.difficile and e. coli), no other significant infections were noted. No patients were found to have malignancy or any other adverse effects of treatment during the reviewed period. CONCLUSION: Dual biologic therapy can be used with improvement in symptomatic and endoscopic findings of IBD. The combination use of two biologic agents does not appear to have additional infectious risk compared to single agent and no other adverse events were described. Longer follow-up and larger patient populations are needed to verify the combination of biologic mechanisms for therapy of refractory IBD and EIMs.

Comparison of Urologist- vs Gastroenterologist-Directed Extracorporeal Shock Wave Lithotripsy for Pancreaticolithiasis.

BACKGROUND & AIMS: Extracorporeal shock wave lithotripsy (ESWL) for pancreaticolithiasis is most commonly performed by urologists. We investigated the effects of transitioning from urologist- to gastroenterologist-directed ESWL on case complexity, process measures, and duct clearance. METHODS: We performed a retrospective study of patients who underwent ESWL for pancreaticolithiasis from 2014 through 2019 at a single center. We collected demographic, clinical, radiographic, and procedural data in duplicate and compared case complexity and process measures between the periods the procedure was performed by urologists (January 2014 through February 2017; 18 patients, 0.47 patients/month) vs gastroenterologists (March 2017 through December 2019; 61 patients; 1.79 patients/month). We also compared data on pancreatic duct stone characteristics and technical success (duct clearance, determined by imaging analysis). RESULTS: There were no differences in patient demographics, comorbidities, pancreatic stone morphology, or time from referral to ESWL during the period the procedure was performed by urologists vs gastroenterologists. Patients received a higher mean number of ESWL shocks per session during the gastroenterology period (4341) than during the urology period (3117) (P < .001). A higher proportion of patients underwent same-session endoscopic retrograde cholangiopancreatography during the gastroenterology time period (66%) than the urology time period (6%) (P < .001). A higher proportion of patients had partial or complete duct clearance during the gastroenterology period (71%) than during the urology period (44%) (P = .04). During the urology period, a higher proportion of patients were hospitalized following ESWL, although there was no difference in captured adverse events between the periods. CONCLUSIONS: Transition from urologist- to gastroenterologist-directed ESWL did not affect case complexity or wait times for ESWL. However, the transition did result in increased procedure volume, more shocks per ESWL session, and improved duct clearance.

Advanced techniques for pancreaticobiliary stone extraction.

BACKGROUND AND AIMS: Pancreaticobiliary stone extraction during endoscopic retrograde cholangiopancreatography can be challenging when working space is limited or the duct is irregular and strictured. We aimed to demonstrate several difficult anatomic scenarios in which stone extraction was accomplished by ductoscopic grasping and retrieval using miniature devices. METHODS: In 2 cases, a miniature retrieval basket and snare are used during cholangioscopy to grasp refractory stones in the intrahepatic and cystic ducts, respectively. In cases 3 and 4, a miniature basket and snare are used during pancreatoscopy to facilitate stone extraction from stenotic and tortuous pancreatic ducts. In case 5, a miniature forceps is used to extract a stone from within a dilated pancreatic side branch. RESULTS: Stone extraction was successful in all cases without adverse events. CONCLUSIONS: Miniature grasping accessories that fit through the working channel of the cholangioscope/pancreatoscope may allow stone retrieval in difficult anatomic scenarios and thus represent a meaningful addition to our therapeutic armamentarium for the treatment of this condition.

Hepatocellular Carcinoma in a Patient With Hepatic Steatosis.

Hepatocellular carcinoma (HCC) has historically developed in the setting of known risk factors-chronic liver disease from viral hepatitis and cirrhosis. In the absence of a risk factor, the development of HCC was rare. However, the increasing prevalence of nonalcoholic liver disease and nonalcoholic steatohepatitis, the paradigm is shifting. Currently, no HCC screening guidelines exist for these patients. We report a 30-year-old man with a medical history of treated nonseminomatous germ cell testicular cancer who presented with asymptomatic transaminitis. Subsequent workup was notable for a 1.6-cm liver lesion. The patient underwent a left lobe wedge resection with pathology demonstrating a well-differentiated HCC in a background of hepatic steatosis.

Lactulose to the Rescue: A Case of Toxic Hepatic Encephalopathy Caused by Portosystemic Shunting and Epistaxis in a Patient with Hereditary Hemorrhagic Telangiectasia.

Hereditary hemorrhagic telangiectasia (HHT) is an uncommon autosomal dominant disorder characterized by telangiectasias and arteriovenous malformations. Multiple organ systems are involved including the skin, lungs, gastrointestinal tract, and brain. Hepatic encephalopathy is an extremely rare complication of HHT and early diagnosis and treatment can be life-saving. We present a rare case of hepatic encephalopathy caused by HHT-induced portosystemic shunting treated with lactulose.
