Oza, Veeral M; Mittal, Nitish; Winchester, Charles; Fazel, Yousef; Manvar, Amar; Goodman, Adam; Girotra, Mohit; Khara, Harshit S; Kothari, Shivangi; Kothari, Truptesh H
Treatment of anastomotic ulcers, also known as marginal ulcers, is challenging, especially when established techniques have failed. PuraStat is a biocompatible synthetic peptide gel that is indicated for hemostasis of bleeding in the gastrointestinal tract and vascular anastomoses. We aim to evaluate the feasibility of PuraStat in the setting of nonhealing anastomotic ulcers when used alongside standard therapies. This is a multicenter case series of adult patients who had PuraStat applied with a follow-up repeat endoscopy. Nine out of 10 patients showed clinical improvement. We concluded that PuraStat is an effective agent to aid in healing of anastomotic ulcer.

GOALS/OBJECTIVE:To investigate the outcomes of hospitalized patients with gastric antral vascular ectasia (GAVE) in the setting of aortic stenosis (AS). BACKGROUND:Although AS is associated with gastrointestinal arteriovenous malformations, its association with GAVE, a rare cause of upper gastrointestinal bleeding, remains unknown. STUDY/METHODS:The National Inpatient Sample database from the years 2016 to 2019 was searched for patients admitted with a diagnosis of GAVE, with and without a history of AS. Univariate and multivariate logistic regression analysis was performed to determine the risk of mortality and in-hospital complications in the GAVE/AS group compared with the GAVE-only group. RESULTS:Patients with AS had a 2-fold increase in the risk of GAVE [odds ratio (OR): 2.08, P < 0.001], with no statistically significant difference in inpatient mortality between the study groups (OR: 1.36, P = 0.268). Patients with GAVE-AS had a higher risk of hypovolemic shock (OR: 2.00, P = 0.001) and acute coronary syndromes (OR: 2.25, P < 0.001) with no difference in risk of cardiogenic shock (P = 0.695), acute kidney injury (P = 0.550), blood transfusion (P = 0.270), sepsis (P = 0.598), respiratory failure (P = 0.200), or in-hospital cardiac arrest (P = 0.638). The cost of care in patients with GAVE-AS was increased by a mean of $4729 (P = 0.022), with no increase in length of stay (P = 0.320) when compared with patients with GAVE-only. CONCLUSIONS:Patients with AS have a 2-fold increase in the risk of development of GAVE. Patients with AS admitted for GAVE-related bleeding are at higher rates of hypovolemic shock, acute coronary syndrome, and higher resource utilization when compared with admitted patients with GAVE without AS.

Aldiabat, Mohammad; Aleyadeh, Wesam; Rana, Tabeer; Ta'ani, Omar Al; Alahmad, Majd; Ayoub, Malek; Jaber, Fouad; Obeidat, Adham; Numan, Laith; Manvar, Amar; Alhuneafat, Laith
BACKGROUND/UNASSIGNED:Delirium is prevalent in elderly patients, linked to elevated mortality rates, heightened healthcare resource use, and caregiver burden. Inflammatory bowel disease (IBD) poses various delirium risk factors, yet the impact on geriatric IBD patient outcomes remains unexplored. METHODS/UNASSIGNED:Using 2016-2019 National Inpatient Sample data, we identified ≥65-year-old patients admitted for IBD (Crohn's, ulcerative colitis) management stratified by delirium presence as a secondary diagnosis. The study aimed to assess delirium's impact on geriatric IBD patient outcomes. RESULTS/UNASSIGNED: < 0.001) compared to those without delirium. CONCLUSION/UNASSIGNED:Elderly IBD patients with delirium face higher mortality risk, prolonged hospitalization, and increased healthcare costs. Clinicians should recognize delirium's detrimental effects in this vulnerable group and adhere to preventive protocols for improved care.

Aldiabat, Mohammad; Kilani, Yassine; Arshad, Iqra; Rana, Tabeer; Aleyadeh, Wesam; Al Ta'ani, Omar; Aljabiri, Yazan; Alsakarneh, Saqr; Abdelfattah, Thaer; Alhuneafat, Laith; Manvar, Amar
OBJECTIVES/OBJECTIVE:To examine the predictors and outcomes associated with the development of acute pancreatitis (AP) in patients hospitalized with Coronavirus Disease 2019 (COVID-19). METHODS:This is an observational analysis of the 2020 National Inpatient Sample Database. The study includes adult patients who were admitted with a confirmed diagnosis of COVID-19 and stratifies them based on the presence or absence of AP during their hospitalization. Predictors of AP development between the two groups and differences in outcomes are examined. Multivariate logistic regression analysis using Stata/BE 17.0 is conducted, with adjustments made for age, sex, race, and Charlson Comorbidity Index (CCI). Statistical significance is determined at a p-value of <0.05. RESULTS:Significant factors associated with an increased risk of AP in COVID-19 patients include Hispanic ethnicity, higher Charlson Comorbidity Index (CCI) score, residence in states located in the southern region, history of chronic kidney disease, chronic liver disease, malnutrition, portal hypertension, and alcohol use. COVID-19 patients who developed AP were also found to be at higher risk of adverse outcomes, including mortality, acute coronary syndrome, acute kidney injury, sepsis, septic shock, in-hospital cardiac arrest, invasive mechanical ventilation, upper gastrointestinal bleeding, prolonged length of stay, and increased healthcare cost. CONCLUSIONS:In hospitalized patients with COVID-19, the presence of AP is associated with increased mortality and morbidity. Risk factors for developing AP in this population include Hispanic ethnicity, residence in the southern region, higher Charlson Comorbidity Index (CCI) score, history of chronic kidney disease, chronic liver disease, malnutrition, portal hypertension, and alcohol use.

Thyroid Metastasis to the Colon [Case Report]
Lewine, Eliza B; Patel, Zinal; Forman, Jacqueline; Manvar, Amar; Hanna, Iman
Approximately 1% of colorectal cancers can be attributed to metastatic neoplasms originating from other primary sources typically the lung, ovary, breast, prostate, kidney, or skin. Metastasis to the colon from the thyroid however is exceedingly rare. We present a 76-year-old man with a history of papillary thyroid carcinoma WHO presented with colon polyps consistent with carcinoma from his papillary thyroid carcinoma. The findings in this report suggest prompt colorectal cancer screening after thyroid cancer diagnosis and regular screening thereafter.

Use of Lumen-apposing Metal Stents for Endoscopic Drainage of Intra-abdominal Fluid Collections in Pediatric Patients
Costa, Peter A; Ho, Sammy; Manvar, Amar; Rivas, Yolanda; Novak, Inna
INTRODUCTION:Intraabdominal fluid collections that previously required surgical intervention can now be drained with less invasive techniques. The use of lumen-apposing metal stents (LAMS) to treat pancreatic pseudocysts and perirectal abscesses has been shown to be a safe and effective technique in adults. We aim to evaluate the indications, outcomes, and complications of the use of LAMS in pediatric patients at our institution. METHODS:A retrospective chart review was performed to study patients up to 18 years of age at the Children's Hospital at Montefiore who underwent drainage of intraabdominal fluid collections with the use of LAMS. The main outcome measures were technical and clinical success and associated adverse events with LAMS placement. RESULTS:Seven patients (2 girls) ranging from 9 to 18 years were identified. Four patients had perirectal abscess postperforated appendicitis and 3 patients had pancreatic pseudocysts. All of the patients had complete resolution of the collections, with no recurrence, and our technical and clinical success rate was 100%. Only 1 patient had mild bleeding after placement that spontaneously resolved. DISCUSSION:Our study demonstrates the efficacy and safety of the use of LAMS for the drainage of intraabdominal fluid collections in pediatric patients, although the number of patients included is limited.

Endoscopic Ultrasound-Guided Hepaticogastrostomy With Lumen-Apposing Metal Stent for Management of Pyogenic Liver Abscess [Case Report]
Desai, Aditi; Manvar, Amar; Ho, Sammy
A 45-year-old man presented with abdominal pain, fever with chills, nonproductive cough, mild pleurisy, and anorexia. Computed tomography scan showed a heterogeneously enhancing mass in the left hepatic lobe with leukocytosis and elevated C-reactive protein. Interval growth of the lesion was noted on magnetic resonance imaging obtained several days after admission. Given the clinical suspicion for pyogenic liver abscess and favorable location in the left hepatic lobe, endoscopic ultrasound-guided drainage was pursued. The patient underwent endoscopic ultrasound-guided hepaticogastrostomy with a lumen-apposing metal stent. His symptoms gradually abated after procedure. Radiographic resolution of the abscess was noted 1 week after stent placement, and the stent was subsequently removed. He had no clinical or radiographic evidence of recurrence at 1-month follow-up.

Histologic Analysis of Endoscopic Ultrasound-Guided Through the Needle Microforceps Biopsies Accurately Identifies Mucinous Pancreas Cysts
Yang, Dennis; Trindade, Arvind J; Yachimski, Patrick; Benias, Petros; Nieto, Jose; Manvar, Amar; Ho, Sammy; Esnakula, Ashwini; Gamboa, Anthony; Sethi, Amrita; Gupte, Anand; Khara, Harshit S; Diehl, David L; El Chafic, Abdul; Shah, Janak; Forsmark, Christopher E; Draganov, Peter V
BACKGROUND & AIMS/OBJECTIVE:It is a challenge to accurately assess pancreatic cystic lesions (PCLs) and determine their risk. We compared the yield of tissue acquired with endoscopic ultrasound (EUS)-guided microforceps (through the needle tissue biopsy [TTNB]) with that of samples collected by EUS-guided fine-needle-aspiration (EUS-FNA), and the accuracy of analyses of each sample type in the diagnosis of mucinous PCLs. METHODS:We performed a prospective open-label study of 114 consecutive adults (56.1% women; mean age, 64.2 y) undergoing EUS-FNA evaluation of PCLs (mean size, 35 mm) at 7 centers, from June 20, 2016, through August 31, 2018. Samples were collected from each cyst by FNA and microforceps; samples collected by FNA were analyzed by cytology and samples collected by TTNB were analyzed by histology. Acquisition yield was defined as the percentage of specimens collected that were adequate for cytologic or histologic analysis. Diagnoses of mucinous cysts were made based on identification of pancreatic mucinous epithelium by cytology analysis of FNA samples or histologic analysis of TTNB samples. Surgical specimens were used as the reference standard when available. RESULTS:The EUS-guided microforceps were successfully inserted into 97.4% (111 of 114) of PCLs. Tissue acquisition yield was significantly higher with TTNB (95 of 114; 83.3%) than FNA (43 of 114; 37.7%) (P < .001). Sixty-one PCLs were determined to be mucinous based on TTNB analysis (53.5%) vs 11 with FNA analysis (9.6%) (P < .001). Among PCLs categorized as equivocal, based on the level of carcinoembryonic antigen, TTNB analysis found 50% (41 of 82) to be mucinous and FNA analysis found 8.5% (7 of 82) to be mucinous (P < .001). Findings from analyses of samples collected by TTNB were 100% concordant with findings from histologic analysis of surgical specimens (14 of 14), whereas only 3 of 14 findings from analysis of samples collected by FNA were in agreement with findings from surgical specimens (21.4%) (P < .001). Four of 5 mucinous PCLs with advanced neoplasia (80%) were detected with TTNB compared with none with FNA (PÂ = .04). Self-limited intracystic bleeding occurred in 7 patients (6.1%), and acute pancreatitis in 6 patients (5.3%). CONCLUSIONS:In a multicenter prospective study of patients undergoing EUS-FNA for evaluation of PCLs, we found TTNB collection of tissues for histologic analysis to be safe and feasible, with an acquisition yield of 83.3%. Histologic analysis of samples collected by TTNB identified a larger proportion of mucinous PCLs compared with cytologic analysis of samples collected by FNA-even among samples categorized as equivocal, based on the level of carcinoembryonic antigen. More samples collected by TTNB than FNA were found to have advanced neoplasia. Clinicaltrials.gov no: NCT02979509.

Afferent Loop Syndrome Due to Volvulus of the Afferent Limb [Case Report]
Desai, Aditi; Manvar, Amar; Ho, Sammy
A 78-year-old woman with a history of stage IIB gastric adenocarcinoma with previous Billroth II subtotal gastrectomy was admitted with pancreatitis, with subsequent development of fevers and acute jaundice. Transabdominal ultrasound demonstrated bile duct obstruction. An endoscopic retrograde cholangiopancreatography was attempted, but the lumen of the afferent limb appeared distorted without an obstructing lesion. A computed tomography scan demonstrated volvulus of the afferent limb near the gastrojejunal anastomosis, with afferent limb dilation and significant biliary dilation.
