    An Unusual Cause of Obstructive Jaundice and Acute Pancreatitis: Visceral Artery Pseudoaneurysm
    (Springer Nature, 2021-04-05) Saito, Akira; Fayad, Nabil; Medicine, School of Medicine
    Visceral artery pseudoaneurysm (VAPA) is an uncommon vascular disorder with a tendency to present with nonspecific signs and abdominal symptoms. This case describes a patient with severe atherosclerosis who developed multiple VAPAs including a hepatic artery pseudoaneurysm bleeding into a large hematoma, which resulted in obstructive jaundice and acute pancreatitis. Prompt diagnosis of VAPA is important due to the high risk of vessel wall perforation with associated increased mortality rate. Biliary obstruction with acute pancreatitis is not a well-described presentation for VAPAs.

    Defining adenoma detection rate benchmarks in average-risk male veterans
    (Elsevier, 2018) El-Halabi, Mustapha M.; Rex, Douglas K.; Saito, Akira; Eckert, George J.; Kahi, Charles J.; Medicine, School of Medicine
    Background and Aims Veterans have higher prevalence of colorectal neoplasia than non-veterans; however, it is not known whether specific Veterans Affairs (VA) adenoma detection rate (ADR) benchmarks are required. We compared ADRs of a group of endoscopists for colonoscopies performed at a VA to their ADRs at a non-VA academic medical center. Methods This was a retrospective review of screening colonoscopies performed by endoscopists who practice at the Indianapolis VA and Indiana University (IU). Patients were average-risk males aged 50 years or older. ADR, proximal adenoma detection rate, advanced adenoma detection rate, and adenomas per colonoscopy were compared between IU and the VA groups. Results Six endoscopists performed screening colonoscopies at both locations during the study period (470 at IU vs 608 at the VA). The overall ADR was not significantly different between IU and the VA (58% vs 61%; p =0.21). Advanced neoplasia detection rate (13% vs 17%; p=0.46), proximal adenoma detection rate (46% vs 47%; p=0.31), and adenoma per colonoscopy (1.59 vs 1.84; p=0.24) were not significantly different. There were no significant differences in cecal intubation rate (100% vs 99%; p=0.13) or withdrawal time (10.9 vs 11.1 min; p=0.28). In regression analysis, there was significant correlation between the attending-specific ADRs at IU and the VA (p=0.041, r-square=0.69). Conclusions In this study of average-risk males undergoing screening colonoscopies by the same group of endoscopists, the ADRs of VA and non-VA colonoscopies were not significantly different. This suggests that a VA-specific ADR target is not required for endoscopists with high ADR.

    Not FIT for Use: Fecal Immunochemical Testing in the Inpatient and Emergency Settings
    (Elsevier, 2022-01) Bhatti, Umer; Jansson-Knodell, Claire; Saito, Akira; Han, Andrew; Krajicek, Edward; Han, Yan; Imperiale, Thomas F.; Fayad, Nabil; Medicine, School of Medicine
    Background Fecal immunochemical testing (FIT) is widely used for colorectal cancer screening, its only indication. Its effect on clinical decision-making beyond screening is unknown. We studied the use of FIT in emergency and inpatient settings and its impact on patient care. Methods Using electronic medical records, we reviewed all non-ambulatory FITs performed from November 2017 to October 2019 at a tertiary care community hospital. We collected data on demographics, indications, gastroenterology consultations, and endoscopic procedures. Multivariate logistic regression was performed to determine the effect of FIT on gastroenterology consultation and endoscopy. Results We identified 550 patients with at least 1 FIT test. Only 3 FITs (0.5%) were performed for colorectal cancer screening. FITs were primarily ordered from the emergency department (45.3%) or inpatient hospital floor (42.2%). Anemia (44.0%), followed by gastrointestinal bleeding (40.9%), were the most common indications. FIT was positive in 253 patients (46.0%), and gastroenterology consultation was obtained for 47.4% (n = 120), compared with 14.5% (n = 43) of the 297 FIT-negative patients (odds ratio 3.28; 95% confidence interval, 2.23-4.82, P < .0001). A potential bleeding source was identified in 80% of patients with reported or witnessed overt gastrointestinal bleeding, a similar proportion (80.7%; P = .92) to patients who were FIT positive with overt gastrointestinal bleeding. Multivariate analysis showed that melena, hematemesis, and a positive FIT were associated with gastroenterology consultation (all P < .05), while only melena (odds ratio 3.34; 95% confidence interval, 1.48-7.54) was associated with endoscopy. Conclusions Nearly all emergency department and inpatient FIT use was inappropriate. FIT resulted in more gastroenterology consultation but was not independently associated with inpatient endoscopy.

    Palliative Care and Hospice Referrals in Patients with Decompensated Cirrhosis: What Factors Are Important?
    (Mary Ann Liebert, Inc., 2020-08) Holden, John H.; Shamseddeen, Hani; Johnson, Amy W.; Byriel, Benjamin; Subramoney, Kavitha; Cheng, Yao-Wen; Saito, Akira; Ghabril, Marwan; Chalasani, Naga; Sachs, Greg A.; Orman, Eric S.; Medicine, School of Medicine
    Background: Palliative care (PC) and hospice care are underutilized for patients with end-stage liver disease, but factors associated with these patterns of utilization are not well understood. Objective: We examined patient-level factors associated with both PC and hospice referrals in patients with decompensated cirrhosis (DC). Design: Retrospective cohort study. Setting/Subjects: Patients with DC hospitalized at a single tertiary center and followed for one year. Measurements: We assessed PC and hospice referrals during follow-up and examined patient-level factors associated with the receipt of PC and/or hospice, as well as associated clinical outcomes. We also examined late referrals (within one week of death). Results: Of 397 patients, 61 (15.4%) were referred to PC, 71 (17.9%) were referred to hospice, and 99 (24.9%) were referred to PC and/or hospice. Two hundred patients (50.4%) died during the one-year follow-up. In multivariable logistic regression, referral to PC was associated with increased comorbidity burden, ascites, increased MELD (Model for End-Stage Liver Disease)-Na score, lack of listing for liver transplant, and unmarried status. Hospice referral was associated with increased comorbidities, portal vein thrombosis, and hepatocellular carcinoma. PC referrals were late in 68.5% of cases, and hospice referrals were late in 62.7%. Late PC referrals were associated with younger age and married status. Late hospice referrals were associated with younger age and recent alcohol use. Conclusions: PC and hospice is underutilized in patients with DC, and most referrals are late. Patient-level factors associated with these referrals differ between PC and hospice.
