Ethnic Variation Trends in the Use of Ileal Pouch-Anal Anastomosis in Patients With Ulcerative Colitis.

Background: Approximately 15%-20% of patients with ulcerative colitis (UC) will require surgery during their lifetime. Ileal pouch-anal anastomosis (IPAA) is the preferred surgical option, which typically requires access to a specialist experienced in surgery for inflammatory bowel diseases (IBD). Methods: The aims of this study are the assessment of the comparative use of IPAA for UC among different racial/ethnic groups and observe trends over the past decade in the United States as well as the comparative assessment of their respective postoperative outcomes. This was an observational retrospective study using the National Inpatient Sample (NIS) 2009-2018 dataset. All patients with ICD-9/10CM codes for UC were included. The primary outcome was comparative trends in IPAA construction across races/ethnicities in the past decade, which was compared to White patients as reference. Multivariate regression analyses were used to adjust for age, gender, Charlson comorbidity index, income in patient zip code, insurance status, hospital region, location, size, and teaching status. Results: The number of patients discharged from US hospitals with an associated diagnosis of UC increased between 2009 and 2018, but the number of patients undergoing an IPAA decreased during that time period. Of 1 153 363 admissions related to UC, 60 688 required surgery for UC, of whom 16 601 underwent IPAA in the study period. Of all the patients undergoing surgery for UC, 2862 (4.7%) were Black, while 44 351 were White. This analysis indicated that Black patients were less likely to undergo IPAA both in 2009 and in 2018 compared to Whites. Hispanic patients were significantly less likely to receive IPAA in 2009 but were no longer less likely to receive IPAA in 2018 when compared to Whites. Conclusions: The use of IPAA among Black patients requiring surgery for UC remains less common than amongst their White counterparts. Further research is needed to determine if racial disparity is a factor in decreased access to specialized care.

Modified Bedside Index for severity in acute pancreatitis (BISAP) score validation in the national inpatient sample database.

PURPOSE: The aim of this study was to build and validate modified score to be used in the healthcare cost and utilization project databases for further classification of acute pancreatitis (AP). MATERIALS AND METHODS: The National Inpatient Sample database for the years 2016-2019 was queried for all primary adult discharge diagnoses of AP. An mBISAP score system was created utilizing the ICD-10CM codes for pleural effusion, encephalopathy, acute kidney injury, systemic inflammatory response, and age >60. Each was assigned a 1-point score. A multivariable regression analysis was built to test for mortality. Sensitivity and specificity analyses were performed for mortality. RESULTS: A total of 1,160,869 primary discharges for AP were identified between 2016 and 2019. The pooled mortality rate was: 0.1%, 0.5%, 2.9%, 12.7%, 30.9% and 17.8% (P â€‹< â€‹0.01), respectively for scores 0 to 5. Multivariable regression analysis showed increasing odds of mortality with each one-point increment: mBISAP score of 1 (adjusted odds ratio [aOR] 6.67; 95% confidence interval [CI] 4.69-9.48), score of 2 (aOR 37.87; 95% CI 26.05- 55.03), score of 3 (aOR 189.38; 95% CI 127.47-281.38), score of 4 (aOR 535.38; 95% CI 331.74-864.02), score of 5 (aOR 184.38; 95% CI 53.91-630.60). Using a cut-off of ≥3, sensitivity and specificity analyses reported 27.0% and 97.7%, respectively, with an area under the curve (AUC) of 0.811. CONCLUSION: In this 4-year retrospective study of a US representative database, an mBISAP score was constructed showing increasing odds of mortality with each 1-point increase and a specificity of 97.7% for a cut-off of ≥3.

Inpatient epidemiology, healthcare utilization, and association with comorbidities of Turner syndrome: A National Inpatient Sample study.

We aimed to investigate the prevalence, resource utilization, and comorbidities of patients with Turner syndrome (TS) hospitalized in the United States. We identified patients within the Nationwide Inpatient Sample database from the year 2017 to 2019. A propensity-matched cohort of non-TS patients from the same database was constructed to serve as comparators. There were 9845 TS patients, corresponding to inpatient prevalence of 10.4 per 100,000 admissions. The most common admission diagnosis was sepsis (27.9%). TS patients had higher inpatient mortality (adjusted odds ratio 2.16, 95% confidence interval 1.57-2.96) and morbidity, including shock, ICU admission, acute kidney injury, systemic inflammatory response syndrome, acute respiratory distress syndrome, and multi-organ failure. Increased risk of comorbidities, such as stroke, myocardial infarction, autoimmune diseases, and non-variceal gastrointestinal bleeding, was observed. TS patients had longer length of stay (LOS; 5.1 days vs. 4.5 days, p < 0.01) and displayed a mean additional $5382 (p < 0.01) in total hospital costs and a mean additional $20,083 (p < 0.01) in total hospitalization charges. In conclusion, hospitalization of patients with TS was associated with a significantly higher inpatient morbidity, mortality, expenditures, and longer LOS compared to non-TS patients. Patients with TS had a higher risk of cardiovascular complications, autoimmune diseases, and gastrointestinal bleeding.

Thromboembolic Events in Hospitalized Patients with Inflammatory Bowel Disease.

BACKGROUND: Inflammatory bowel disease (IBD) has been associated with an increased risk of thromboembolic vascular complications. Although studies from the National Inpatient Sample (NIS) examined this association to some extent, sub-stratification for Crohn's disease (CD) and ulcerative colitis (UC) in larger studies is lacking. The aims of this study were to utilize the NIS to determine the prevalence of thromboembolic events in inpatients with IBD compared to in patients without IBD and to explore the inpatient outcomes like morbidity, mortality, and resource utilization in patients with IBD and thromboembolic events as stratified by disease subtype. METHODS: This was a retrospective observational study using the NIS 2016. All patients with ICD10-CM codes for IBD were included. Patients with thromboembolic events were identified using diagnostic ICD codes and stratified into 4 categories: (1) Deep vein thrombosis (DVT), (2) Pulmonary embolism (PE), (3) Portal vein thrombosis (PVT), and (4) Mesenteric ischemia, which were then sub-stratified for CD and UC. The primary outcome was the inpatient prevalence and odds of thromboembolic events in patients with IBD compared to without IBD. Secondary outcomes were inpatient morbidity, mortality, resource utilization, colectomy rates, hospital length of stay (LOS), and total hospital costs and charges compared to patients with IBD and thromboembolic events. RESULTS: A total of 331,950 patients with IBD were identified, of who 12,719 (3.8%) had an associated thromboembolic event. For the primary outcome, after adjusting for confounders, inpatients with IBD had higher adjusted odds of DVT (aOR 1.59, p < 0.001), PE (aOR 1.20, p < 0.001), PVT (aOR 3.18, p < 0.001) and mesenteric ischemia (aOR 2.49, p < 0.001) compared to inpatients without IBD, an observation which was confirmed for both patients with CD and UC. Inpatients with IBD and associated DVT, PE and mesenteric ischemia had higher morbidity, mortality, odds of colectomy, cost, and charges. CONCLUSIONS: Inpatients with IBD have higher odds of associated thromboembolic disorders compared to patients without IBD. Furthermore, inpatients with IBD and thromboembolic events have significantly higher mortality, morbidity, colectomy rates and resource utilization. For these reasons, increased awareness and specialized strategies for the prevention and management of thromboembolic events should be considered in inpatients with IBD.

Outcomes of endoscopic retrograde cholangiopancreatography in patients with inflammatory bowel disease: a nationwide study.

PURPOSE: Endoscopic retrograde cholangiopancreatography (ERCP) has become a commonly utilized procedure for both diagnostic and therapeutic purposes. There is a paucity of data for patients with inflammatory bowel disease (IBD) who undergo ERCP. The aim of this study is to examine the indications, complications, and inpatient outcomes of patients with IBD undergoing ERCP. METHODS: For this retrospective cohort study, we utilized the National Inpatient Sample database for the years 2018-2019. We compared potential indications, outcomes, ERCP-related procedures, and resource utilization in patients who underwent ERCP and had a diagnosis of IBD to that of patients who underwent ERCP without a diagnosis of IBD. We utilized a multivariate regression model that accounted for several potential confounders. RESULTS: We identified 318,590 ERCP procedures. Among them, 3625 ERCP procedures were performed in patients with an associated diagnosis of IBD. Patients with IBD who underwent ERCP had higher odds of acute kidney injury (aOR 1.27; 95% CI: 1.01-1.60) and sepsis (aOR 1.33; 95% CI: 1.07-1.67) compared to patients without IBD. However, inpatient mortality and other complications were not statistically different between the two groups. Patients with IBD were also less likely to undergo biliary sphincterotomy (aOR 0.75; 95% CI: 0.62-0.88) but there were no other differences in performance of ERCP-related therapeutic interventions between the two groups. Adjusted costs and charges were not statistically different between the two groups. CONCLUSION: Our study shows that ERCP is, overall, a safe procedure in patients with IBD, as inpatient morbidity and mortality are similar to patients without IBD.

Incidence, Burden, and Predictors of 11-Month Readmission in Patients Undergoing Bariatric Surgery.

BACKGROUND: Bariatric surgery (BSx) is one of the most common surgical procedures performed in the USA. Nonetheless, data regarding 11-month period after BSx remain limited. METHODS: A retrospective cohort study using the 2016 National Readmission Database. Adult patients admitted for BSx in January were included. The follow-up period was 11 months (February-December). The primary outcome was all-cause 11-month readmission. Secondary outcomes were index admission (IA) and readmission in-hospital mortality rate and healthcare resource use associated with readmission. Multivariate regression was performed to identify independent risk factors for readmission. RESULTS: A total of 13,278 IA were included. The 11-month readmission rate was 11.1%. The mortality rate of readmission was 1.4% and 0.1% for IA (P < 0.01). The most common cause of readmission was hematemesis. Independent predictors were Charlson comorbidity index (CCI) score ≥ 3 (adjusted hazard ratio [aHR] 1.34; P = 0.05), increasing length of stay (aHR 1.01; P < 0.01), transfer to rehabilitation facilities (aHR 5.02; P < 0.01), undergoing laparoscopic Roux-en-Y gastric bypass (aHR 1.71; P = 0.02), adjustable gastric band (aHR 14.09; P < 0.01), alcohol use disorder (2.10; P = 0.01), and cannabis use disorder (aHR 3.37; P = 0.01). Private insurance as primary payer (aHR 0.65; P < 0.01) and BMI 45-49 kg/m2 (aHR 0.72; P < 0.01) were associated with less odds of readmission. The cumulative total hospitalization charges of readmission were $69.9 million. CONCLUSIONS: The 11-month readmission rate after BSx is 11.1%. Targeting modifiable predictors of readmission may help reduce the burden of readmissions on our healthcare system.

Factors That Influence the Speed and Completion of Double Balloon Enteroscopy in Patients with Arteriovenous Malformations.

BACKGROUND: Double balloon enteroscopy remains a resource and time-intensive procedure that is not available in many endoscopy units. AIMS: We aimed to identify variables impacting the speed and completion of double balloon enteroscopy. METHODS: We retrospectively reviewed 550 patients. Using a mean time and distance for both the antegrade and retrograde approach, we determined the procedure speed and assessed factors that influenced it. In addition, we assessed the factors that contributed to a complete double balloon enteroscopy. RESULTS: A total of 386 antegrade and 164 retrograde double balloon enteroscopies were performed. Greater than 10 AVMs requiring treatment was a negative predictor (AOR 0.25, CI 0.11-0.51, p < 0.001), whereas age greater than 60 years (AOR 2.66, CI 1.18-6.65, p = 0.025) was a positive predictor of a fast antegrade enteroscopy. For retrograde, prior abdominal surgery was the only factor that trended to significance (AOR 0.38, CI 0.14-0.99, p = 0.052). A total of 120 combined procedures were performed. Female gender (AOR 2.62, CI 1.16-6.24, p = 0.02), history of prior abdominal surgery (AOR 0.31, CI 0.13-0.70, p = 0.006) and Boston bowel pre-preparation score of greater than 6 (AOR 4.50, CI 1.59-14.30, p = 0.006) were the only significant predictors of a complete procedure. CONCLUSION: By applying double balloon enteroscopy speed, a novel method of measuring procedure efficiency, we were able to more reliably identify the factors that will negatively impact the speed and success of the procedure.

Splenic injury is an under-recognized adverse event of in-patient colonoscopy: a nationwide analysis.

Background and study aims Splenic injury (SI) during colonoscopy is an underappreciated adverse event. Our aim was to examine the occurrence and outcomes of patients who developed SI after inpatient colonoscopy using a nationwide dataset. Patients and methods Retrospective, observational study using the National Inpatient Sample (NIS) between 2012 and 2018. All patients with ICD9/10CM procedural codes for colonoscopy with or without SI were included. The primary outcome was the association between SI and inpatient colonoscopy. Secondary outcomes were inpatient morbidity, mortality, resource utilization, splenectomy rates, hospital length of stay and total hospital costs and charges. Comparative analyses were performed between patients with and without SI. Multivariate regression analyses were utilized. Results A total of 2,258,040 of inpatient colonoscopies were included. Of these, 240 had associated SI and 25 patients required splenectomy (10.4 %). The incidence of colonoscopy-associated SI remained relatively stable between 2012 and 2018 (0.033 % versus 0.020 %, respectively). The mean age of patients with and without SI was 63.7 and 64.1 years, respectively. The occurrence of SI was calculated as 10.63 cases per 100,000 inpatient colonoscopies. Patients who had associated SI displayed significantly higher odds of inpatient mortality (aOR: 14.45) and ICU stay (aOR: 10.11) compared to those without SI. Conclusions Splenic injury confers significantly higher odds of inpatient mortality, and resource utilization. The incidence of SI related to colonoscopy remained stable during the study period. Although uncommon, SI should be considered when encountering patients with abdominal pain after colonoscopy.

The Burden of Vaccine-preventable Diseases in Patients With Inflammatory Bowel Disease.

BACKGROUND: Patients with inflammatory bowel disease (IBD) are at an increased risk of infections, including vaccine-preventable diseases (VPDs). The aim of this study was to explore the inpatient prevalence of VPD in patients with IBD, as well as inpatient outcomes. METHODS: Retrospective study using the 2013-2017 Nationwide Inpatient Sample databases. All patients 18 years of age or older with International Classification of Diseases, Ninth and 10th Revisions , Clinical Modification (ICD-9/10 CM) codes for IBD were included, as well as patients with VPDs as a principal diagnostic code. The primary outcome was the occurrence and odds of VPD in patients with IBD compared with patients with no IBD. Secondary outcomes were inpatient mortality, morbidity, and economic burden compared with patients with IBD and non-vaccine-preventable infections (VPIs). Multivariate regression yielded adjusted odds ratios. RESULTS: Of 1,622,245 (0.9%) patients with a diagnosis of IBD, 3560 (0.2%) had associated VPDs, while 131,150 patients had non-VPI (8.1%). The most common VPDs were influenza, herpes zoster (HZ), pneumococcal pneumonia, and varicella. Only HZ and varicella had increased odds of occurrence in patients with IBD of all ages. Patients with IBD 65 years of age or older had increased odds of VPD compared with patients under 65 years. Patients with IBD and associated VPD had higher odds of intensive care unit stay, systemic inflammatory response syndrome, and multiorgan failure compared with patients with IBD and non-VPI. CONCLUSIONS: VPDs represent a clinically relevant cause of infectious disease-related hospital admissions in patients with IBD. Patients with IBD are at increased risk for hospitalization due to HZ and varicella. Those hospitalized for VPD have higher morbidity compared with patients with IBD and non-VPI. These findings echo the importance of instituting optimal immunization schedules in patients with IBD, particularly in patients 65 years or older.

Cytomegalovirus-related colitis in patients with inflammatory bowel disease.

PURPOSE: We aimed to examine the role of cytomegalovirus (CMV) infection in patients with inflammatory bowel disease (IBD), which remains highly debated. METHODS: Retrospective, observational study using the Nationwide Inpatient Sample (NIS) 2015-2017. Patients with ICD9/10CM codes for Crohn's disease (CD), ulcerative colitis (UC), and CMV colitis were included in the study. The primary outcome was the odds of CMV colitis in patients with IBD compared to patients without IBD. Secondary outcomes were differences in inpatient morbidity, mortality, resource utilization, colectomy rates, hospital length of stay (LOS), and inflation-adjusted total hospitalization costs. RESULTS: A total of 992,445 patients with IBD were identified, out of which 520 (0.05%) had associated CMV colitis. Patients with IBD had significantly higher odds of CMV colitis compared to patients without IBD (aOR: 19.76, p < 0.01), having an even greater association with UC (aOR: 31.13, p < 0.01). CMV colitis in patients with CD was associated with a significant increase in odds of mortality, shock, and ICU stay, while patients with UC had higher odds of colectomy. The patients with IBD and CMV colitis had higher odds of acute kidney injury, multiorgan failure, markedly increased additional hospital costs, and LOS compared to patients with IBD and no CMV colitis. CONCLUSION: IBD has a significant association with CMV colitis, and the presence of CMV colitis in patients with IBD was associated with higher mortality, morbidity, and hospital costs. Prospectively designed studies may better elucidate the risk factors and impact of CMV colitis on patients with IBD.

The use of ileal pouch-anal anastomosis in patients with ulcerative colitis from 2009 to 2018.

AIM: The existing literature was updated, assessing the use of surgery in patients with ulcerative colitis in more recent years. METHODS: This was a retrospective observational study identifying all patients with ulcerative colitis within the National Inpatient Sample, years 2009-2018. All patients with International Classification of Diseases, Ninth and Tenth Revisions, Clinical Modification diagnostic codes for ulcerative colitis were included. The primary outcome was the trend in total number of total abdominal colectomy, proctocolectomy and simultaneous versus delayed pouch construction. RESULTS: A total of 1 184 711 ulcerative-colitis-related admissions were identified. An increase of 18.6% in the number of patients was observed, while the number of surgeries decreased. A total of 40 499 patients underwent total colectomy, annually decreasing from 5241 to 3185. The number of proctocolectomies without pouch decreased from 1191 to 530, while the number of patients undergoing pouch construction decreased from 2225 to 1284. The proportion of patients undergoing initial pouch at time of proctocolectomy decreased from 995 (45%) to 265 (21%), while the proportion of patients undergoing delayed pouch construction in 2018 was 79% (n = 1120). CONCLUSION: Surgery use in ulcerative colitis has decreased in the last decade despite increasing numbers of hospital admissions in patients with this condition. While the overall proportion of patients undergoing pouch construction remained stable, the majority of patients were initially treated with total colectomy and their ileal pouches werre constructed in a delayed fashion.

Pancreatic Disorders in Patients with Inflammatory Bowel Disease.

Inflammatory bowel disease (IBD) can involve multiple organ systems, and pancreatic manifestations of IBD are not uncommon. The incidence of several pancreatic diseases is more frequent in patients with Crohn's disease and ulcerative colitis than in the general population. Pancreatic manifestations in IBD include a heterogeneous group of disorders and abnormalities ranging from mild, self-limited disorders to severe diseases. Asymptomatic elevation of amylase and/or lipase is common. The risk of acute pancreatitis in patients with IBD is increased due to the higher incidence of cholelithiasis and drug-induced pancreatitis in this population. Patients with IBD commonly have altered pancreatic histology and chronic pancreatic exocrine dysfunction. Diagnosing acute pancreatitis in patients with IBD is challenging. In this review, we discuss the manifestations and possible causes of pancreatic abnormalities in patients with IBD.

Confocal Laser Endomicroscopy in the Diagnosis of Biliary and Pancreatic Disorders: A Systematic Analysis.

BACKGROUND/AIMS: Endoscopic visualization of the microscopic anatomy can facilitate the real-time diagnosis of pancreatobiliary disorders and provide guidance for treatment. This study aimed to review the technique, image classification, and diagnostic performance of confocal laser endomicroscopy (CLE). METHODS: We conducted a systematic review of CLE in pancreatic and biliary ducts of humans, and have provided a narrative of the technique, image classification, diagnostic performance, ongoing research, and limitations. RESULTS: Probe-based CLE differentiates malignant from benign biliary strictures (sensitivity, ≥89%; specificity, ≥61%). Needlebased CLE differentiates mucinous from non-mucinous pancreatic cysts (sensitivity, 59%; specificity, ≥94%) and identifies dysplasia. Pancreatitis may develop in 2-7% of pancreatic cyst cases. Needle-based CLE has potential applications in adenocarcinoma, neuroendocrine tumors, and pancreatitis (chronic or autoimmune). Costs, catheter lifespan, endoscopist training, and interobserver variability are challenges for routine utilization. CONCLUSION: CLE reveals microscopic pancreatobiliary system anatomy with adequate specificity and sensitivity. Reducing costs and simplifying image interpretation will promote utilization by advanced endoscopists.

Esophageal Stricture Recalcitrant to Repeated Dilation in Complex Rheumatological Disease.

We report a case of severe refractory esophageal strictures in the setting of rheumatological disease found to be secondary to isolated esophageal autoimmune bullous disease. She had a history of Sjogren syndrome and esophageal strictures with many previous dilations. After rheumatological workup, she was diagnosed with mixed connective tissue disease. Biopsy showed complement and immunoglobulin G deposition in the basement membrane consistent with bullous lupus or bullous pemphigoid. She had no cutaneous bullae and was diagnosed with isolated esophageal bullous disease. She required multiple dilatations over several months of treatment and was started on mycophenolate mofetil with clinical improvement.

Artificial intelligence in gastroenterology: A state-of-the-art review.

The development of artificial intelligence (AI) has increased dramatically in the last 20 years, with clinical applications progressively being explored for most of the medical specialties. The field of gastroenterology and hepatology, substantially reliant on vast amounts of imaging studies, is not an exception. The clinical applications of AI systems in this field include the identification of premalignant or malignant lesions (e.g., identification of dysplasia or esophageal adenocarcinoma in Barrett's esophagus, pancreatic malignancies), detection of lesions (e.g., polyp identification and classification, small-bowel bleeding lesion on capsule endoscopy, pancreatic cystic lesions), development of objective scoring systems for risk stratification, predicting disease prognosis or treatment response [e.g., determining survival in patients post-resection of hepatocellular carcinoma), determining which patients with inflammatory bowel disease (IBD) will benefit from biologic therapy], or evaluation of metrics such as bowel preparation score or quality of endoscopic examination. The objective of this comprehensive review is to analyze the available AI-related studies pertaining to the entirety of the gastrointestinal tract, including the upper, middle and lower tracts; IBD; the hepatobiliary system; and the pancreas, discussing the findings and clinical applications, as well as outlining the current limitations and future directions in this field.
