    Introduction: Elective therapeutic endoscopy is an important component of care of cirrhotic patients, but there are concerns regarding the risk of bleeding. This study examined the incidence, risk factors, and outcomes of bleeding after endoscopic variceal ligation (EVL), colonoscopic polypectomy, and endoscopic retrograde cholangiopancreatography with sphincterotomy in cirrhotic patients. Methods: A cohort study of patients with cirrhosis who underwent the above procedures at a single center between 2012 and 2014 was performed. Patients with active bleeding at the time of procedure were excluded. Patients were followed for 30 days to assess for postprocedural bleeding and for 90 days for mortality. Results: A total of 1,324 procedures were performed in 857 patients (886 upper endoscopies, 358 colonoscopies, and 80 endoscopic retrograde cholangiopancreatograpies). After EVL, bleeding occurred in 2.8%; after polypectomy, bleeding occurred in 2.0%; and after sphincterotomy, bleeding occurred in 3.8%. Independent predictors of bleeding after EVL and polypectomy included younger age and lower hemoglobin. For EVL, bleeding was also associated with infection and model for end-stage liver disease-Na. International normalized ratio was associated with bleeding in univariate analysis only, and platelet count was not associated with bleeding in any procedure. Bleeding after EVL was associated with 29% 90-day mortality, and bleeding after polypectomy was associated with 14% mortality. Of the 3 patients with postsphincterotomy bleeding, none were outliers regarding their baseline characteristics. Discussion: In patients with cirrhosis, bleeding occurs infrequently after elective therapeutic endoscopy and is associated with younger age, lower hemoglobin, and high mortality. Consideration of these risk factors may guide appropriate timing and preprocedural management to optimize outcomes.

    Colonic Myeloid Sarcoma as a Rare Presentation of Relapsed Acute Myeloid Leukemia
    (Wolters Kluwer, 2020-06-15) Phatharacharukul, Parkpoom; Fayad, Nabil; Siwiec, Robert; Medicine, School of Medicine
    Myeloid sarcoma (MS), an extramedullary tumor of immature granulocytic cells, affects the gastrointestinal tract in approximately 10% of cases. MS involvement of the colon and rectum is considered to be extremely rare. We present a 36-year-old woman with acute myeloid leukemia and allogenic hematopoietic stem cell transplant 2 years before who was admitted with abdominal pain and nonmucous, nonbloody diarrhea. Colonoscopy revealed an ulcerated mass in the proximal colon, and biopsies showed MS compatible with acute myeloid leukemia relapse.

    Delayed Removal of Entrapped Snare in Colonoscopic Polypectomy
    (Wolters Kluwer, 2021-01-27) Phatharacharukul, Parkpoom; Wajid, Maryiam; Fatima, Hala; Medicine, School of Medicine
    Snare entrapment is a rare complication of hot snare polypectomy of large colon polyps. We report a case of snare entrapment in our unit and its management. This report highlights the method of delayed removal of snare followed by repeat colonoscopy.

    Improvement of Osteoporosis Screening among Inflammatory Bowel Disease Patients at Gastroenterology Fellows’ Clinics
    (Hindawi, 2020-06-19) Wehbeh, Antonios; Phatharacharukul, Parkpoom; Fayad, Nabil F.; Medicine, School of Medicine
    Introduction Individuals with inflammatory bowel disease (IBD) have an increased risk of osteoporosis compared to the general population. We aimed to improve the osteoporosis screening rate in the IBD patient population of the gastroenterology (GI) fellows' continuity clinics. Methods Baseline preintervention data were collected on patients seen from July through September of 2018. Four simplified criteria for osteoporosis screening were extrapolated from 3 national guidelines. Among patients who met any of these criteria, we determined the baseline screening rate. Fellows were then educated with a didactic session and handout material, and a standardized template was incorporated into clinic notes. Following this intervention, screening rates were reassessed from December 2018 through February 2019. Results During the preintervention phase, fellows saw 80 patients with IBD. Dual-energy X-ray absorptiometry (DEXA) scan was obtained in 44% of IBD patients who qualify for screening at the county hospital clinic compared to 21% of veterans' clinic IBD patients. In the postintervention period, screening rates remarkably improved to 100% in the county hospital clinic and to 75% in the veterans' clinic. Overall, the screening rate increased by 56% (P < 0.001). Conclusions A large percentage of IBD patients at risk for osteoporosis did not have appropriate bone mass density testing. Educating GI fellows and adding a template to clinic notes were effective in significantly improving the number of patients at risk of osteoporosis to receive appropriate screening test, a DEXA scan. Similar educational interventions should be considered for providers caring for IBD patients to prevent complications of osteoporosis in these patients.

    Incidence and Risk Factors of Recurrent Clostridioides difficile Infection in Patients With Cirrhosis
    (Wolters Kluwer, 2020-07-13) Phatharacharukul, Parkpoom; Purpura, Russell D.; Gandhi, Devika; Xu, Huiping; Bickett-Burkhart, Katie; Chalasani, Naga; Fischer, Monika; Orman, Eric S.; Biostatistics, School of Public Health
    INTRODUCTION: Clostridioides difficile infection (CDI) is common in patients with cirrhosis and is associated with poor outcomes. CDI risk factors in this population have been well characterized; however, risk factors of recurrent CDI (R-CDI) after treatment have not been explored. We sought to estimate the incidence of R-CDI and its associated risk factors in patients with cirrhosis. METHODS: We performed a cohort study of patients with cirrhosis hospitalized with CDI between 2012 and 2016. We collected patient characteristics, including detailed information on the CDI, features of the underlying liver disease, and outcomes including R-CDI, hospital readmission, and mortality. R-CDI was defined as CDI occurring 2–8 weeks after the initial episode. Cox proportional hazards model was used to identify variables independently associated with the outcomes. RESULTS: A total of 257 hospitalized patients with cirrhosis and CDI were included. CDI was community associated in 22.6%. The incidence of R-CDI was 11.9%. R-CDI was not significantly associated with medications at hospital admission or discharge. Independent risk factors of R-CDI included increased Charlson Comorbidity Index (hazard ratio [HR] 1.30; 95% confidence interval [CI]: 1.09–1.55) and use of lactulose (HR 2.58; 95% CI: 1.09–6.09). The 30-day readmission rate was 37%, and readmission was associated with increased Charlson Comorbidity Index (HR 1.12; 95% CI: 1.03–1.23) and Model for End-Stage Liver Disease score (HR 1.04; 95% CI: 1.01–1.07). The 90-day mortality was 22.8%. DISCUSSION: In patients with cirrhosis, R-CDI is associated with comorbidity burden and lactulose use. Attention to these factors might aid clinicians in efforts to prevent R-CDI and improve outcomes in this population.
