Small Bowel Adenocarcinoma: a Nationwide Population-Based Study.

PURPOSE: Small intestinal cancers have a non-specific clinical presentation and hence a delayed diagnosis. The prevalence of small intestinal cancers is low, and there are no cost-effective methods of screening. This study aimed to identify clinical characteristics of duodenal and jejunal adenocarcinomas that can assist in the early detection and diagnosis of disease. METHODS: Duodenal adenocarcinoma and jejunal adenocarcinoma in Explorys database (1999-2019) were compared using odds ratio (OR) with 95% confidence intervals. Data on demographic characteristics, risk factors, clinical features, and treatment were collected. RESULTS: Out of a total of 8100 patients with a diagnosis of primary adenocarcinoma of the small intestine, 5110 are primary adenocarcinoma of duodenum (63%), and 600 are primary adenocarcinoma of jejunum (7.4%). Patients with jejunal adenocarcinoma when compared with patients with duodenal adenocarcinoma are more obese (OR, 1.36) and have a significantly higher prevalence of malignant neoplasm of colon (OR, 3.07), Crohn's disease (OR, 4.42), and celiac disease (OR, 2.48). Jejunal adenocarcinoma patients presented more frequently with intestinal obstruction (OR, 1.99), whereas duodenal adenocarcinoma patients more commonly presented with iron deficiency anemia (OR, 0.16). Patients with jejunal adenocarcinoma are less likely to undergo therapy with anti-neoplastic agents when compared with duodenal adenocarcinoma (OR, 0.81). There are no differences in patients undergoing surgical intervention or a combination of surgical intervention and antineoplastic therapy. CONCLUSIONS: Jejunal adenocarcinoma is more commonly associated with colorectal cancer, celiac disease, and Crohn's disease. They also had lower odds of requiring chemotherapeutic agents.

Disparities in Hepatocellular Cancer Screening in Cirrhotic Patients With Psychiatric Disorders.

Background Patients with psychiatric disorders are at an increased risk of developing liver diseases, including hepatocellular carcinoma (HCC). HCC is a leading cause of cancer-related deaths in the United States. The aim of this study was to re-examine the association of psychiatric illness with HCC and assess its impact on screening practices and the outcomes of HCC. Materials and methods We performed a retrospective manual chart review of all patients diagnosed with HCC at a major safety-net hospital in Cleveland, Ohio, from January 2010 to December 2019. Patients were divided into two groups, those with and those without psychiatric illness. The patient characteristics recorded included psychiatric illnesses, etiology of liver disease, radiographic screening intervals, and tumor board recommendations upon initial diagnosis. We analyzed data using Statistical Product and Service Solutions version 26.0 (IBM Corp., Armonk, NY). We analyzed the qualitative and quantitative differences between the groups using the chi-square or Fisher's exact tests for categorical variables and t-test for continuous variables. Results There were a total of 393 patients with a diagnosis of HCC. Among them, 128 (32.5%) were diagnosed with at least one psychiatric illness. Fewer patients with psychiatric illness (33.6%) underwent screening within six months before being diagnosed with HCC compared to those without psychiatric illness (49.8%) (p = 0.002). Patients with psychiatric illness (71.1%) were more likely to have been seen by a gastroenterologist or hepatologist before their diagnosis of HCC compared to those without psychiatric illness (55.1%) (p =0.002). Patients with psychiatric illness were more likely to be offered systemic chemotherapy or hospice (39.1%) compared to those without psychiatric illness (29.1%) (p =0.039). Discussion A significant number of HCC patients in our study group have an underlying psychiatric illness. Patients with psychiatric disorders are prone to high-risk behaviors, likely predisposing them to chronic liver disease and HCC. Patients with psychiatric disorders are less compliant with screening practices. Our findings suggest that psychiatric illnesses tend to be diagnosed with more extensive HCC, which is less amenable to curative treatment. Significant efforts need to be made to identify barriers to HCC screening in cirrhotic patients with psychiatric disorders.

Quantifying risk factors for microscopic colitis: A nationwide, retrospective cohort study.

BACKGROUND: Microscopic colitis (MC) is associated with several risk factors; however, their relative risk has been variable and not thoroughly evaluated. We aimed to quantify the risk of medical comorbidities and medications associated with MC and treatment offered to these patients. METHODS: A population-based retrospective analysis in International Business Machines (IBM) Explorys (1999-2018), a pooled, de-identified database of 63 million patients in the USA, was performed. Odds ratios (OR) were calculated between MC and other diseases/medications. MC patients were also stratified by age to assess trends of MC in different age groups. RESULTS: A total of 1130 patients had MC in the database. Among medications, non-steroidal anti-inflammatory agents (OR, 20.2) and proton pump inhibitors (OR, 12.1) were associated with highest odds of MC. Among medical comorbidities, infectious gastroenteritis (OR, 26.6) and celiac disease (OR, 22.5) had the highest odds of being associated with MC. Tobacco smoking, psoriasis, Sjogren's syndrome, Clostridium difficile infection, and malabsorption syndromes all conferred odds greater than 10. CONCLUSION: Early identification of MC is critical for minimizing morbidity and mortality. Epidemiologic information can be integrated with current clinical algorithms to more rapidly identify patients at risk.

Pneumatic dilation for esophageal achalasia: patient selection and perspectives.

Achalasia is an esophageal motility disorder characterized by esophageal aperistalsis and impaired relaxation of the lower esophageal sphincter. Treatment is palliative, aimed at decreasing the lower esophageal sphincter pressure. Pneumatic dilation (PD) is a safe and effective treatment for achalasia. Several other invasive and minimally invasive treatment modalities, such as Laparoscopic Heller Myotomy (LHM) and Peroral Endoscopic Myotomy (POEM), also have a comparable safety and efficacy profile to PD. The current review focuses on the indications, contraindications, techniques, and outcomes of PD in various patient populations and its comparison to LHM and POEM. This review also provides relevant information to help endoscopists identify those patients who will benefit the most from PD.

Primary follicular lymphoma of colon: A case series and review of literature.

Follicular lymphoma of the colon is rare, accounting for 1% to 2% of cases in the gastrointestinal tract. Despite the absence of randomized clinical trials, NCCN stage III and IV colonic follicular lymphomas are routinely treated with chemotherapy with good clinical response. We present 2 cases of advanced stage follicular lymphoma of colon that were effectively treated with bendamustine-based chemotherapy regimens.

Pseudomelanosis coli, its relation to laxative use and association with colorectal neoplasms: A comprehensive review.

Pseudomelanosis coli is historically associated with anthraquinone laxatives and is often used as a surrogate marker for chronic laxative use. The opioid epidemic has seen an increase in laxative use for chronic constipation. Anthraquinone laxatives have demonstrated tumorigenic potential in animal studies due to their apoptotic effects on colonic epithelial cells. Colorectal cancer is associated with significant mortality and morbidity worldwide. Human studies have not shown a significant correlation between anthraquinone laxative use, pseudomelanosis coli, and colorectal carcinoma. The characteristic pigmentation of pseudomelanosis also appears to be absent macroscopically and on histology of neoplastic epithelium. However, there appears to be a slightly higher risk of adenoma development. This has been attributed to a higher polyp detection rate during endoscopy on account of the color contrast between the polyp against a darker background of pseudomelanosis.

COVID-19 in Chronic Liver Disease and Liver Transplantation: A Clinical Review.

The coronavirus disease 2019 (COVID-19) pandemic has brought challenges to clinicians caring for patients with chronic liver disease. In the past 6 months, COVID-19 has led to over 150,000 deaths in the United States and over 660,000 deaths around the world. Mounting evidence suggests that chronic liver diseases can have an adverse effect on the clinical outcomes of patients with COVID-19. We present a comprehensive review of the latest literature on preexisting liver diseases and its interrelationship with COVID-19 infection in cirrhosis, hepatocellular carcinoma, nonalcoholic fatty liver disease, autoimmune hepatitis, and viral hepatitis B. As social distancing and telemedicine gain new footing, we synthesize recommendations from 3 major hepatology societies [American Association for the Study of Liver Disease (AASLD), the European Association for the Study of Liver (EASL), and the Asian Pacific Association for the Study of Liver (APASL)] to present the best approaches for caring for patients with liver diseases as well as those requiring liver transplantation.

Endoscopic sleeve gastroplasty versus laparoscopic sleeve gastrectomy: a case-matched study.

BACKGROUND AND AIMS: Endoscopic sleeve gastroplasty (ESG) reduces the gastric lumen to a size comparable with that of laparoscopic sleeve gastrectomy (LSG). However, there is a paucity of research comparing outcomes between the 2 procedures. Our study compared the 6-month weight loss outcomes and adverse events of ESG with LSG in a case-matched cohort. METHODS: We retrospectively reviewed prospectively collected data for patients undergoing ESG or LSG at a single academic center. Weight was recorded at 1 and 6 months postprocedure, and percent total body weight loss (%TBWL) was calculated. Adverse events and new-onset Gastroesophageal Reflux Disease (GERD) were also recorded. RESULTS: A total of 54 ESG patients were matched with 83 LSG patients by age, sex, and body mass index. The proportion of patients with GERD at baseline was similar in the 2 groups (16.7% in ESG group vs 25.3% in LSG group, P = .27). At the 6-month follow-up, %TBWL (compared with baseline) was significantly lower in the ESG group compared with the LSG group (17.1% ± 6.5% vs 23.6% ± 7.6%, P < .01). ESG patients had significantly lower rates of adverse events compared with LSG patients (5.2% vs 16.9%, P < .05). New-onset GERD was also significantly lower in the ESG group compared with the LSG group (1.9% vs 14.5%, P < .05). CONCLUSIONS: ESG, a minimally invasive same-day procedure, achieved less weight loss at 6 months than LSG, with the caveat that LSG caused more adverse events and new-onset GERD than ESG.

All that glitters is not gold: A case of lanthanum carbonate aspiration.

INTRODUCTION: Foreign body aspiration is a significant cause of morbidity and mortality in elderly hospitalized patients. These are typically small items that patients have access to, including small coins. CASE PRESENTATION: This is a case report of a 75-year-old man recently bedridden from a large hemispheric stroke with sudden onset of hoarseness, cough and dysphagia. A chest X-ray was obtained which showed a radiopaque coin-shaped foreign body, presumably a coin in his aerodigestive tract. He was promptly taken to the endoscopy suite for upper endoscopy. During endoscopy, it was determined that the foreign body was a radiopaque medication that he had been given. It was easily and safely able to be crushed and lavaged down into his stomach and later determined to be lanthanum carbonate, a commonly used phosphate binder. Following endoscopy, the patient's cough, hoarseness and dysphagia resolved with no long-term complications. DISCUSSION: Lanthanum carbonate is a phosphate-binding medication used in the management and treatment of hyperphosphatemia commonly seen in patients with end-stage renal disease, which is radiopaque. There are few published reports and images of radiopaque fragments of medication in the gastrointestinal tract but none causing aspiration by masquerading as a coin-like density in the aerodigestive tract as we present here.

Primary versus redo paraesophageal hiatal hernia repair: a comparative analysis of operative and quality of life outcomes.

INTRODUCTION: We compared patient outcomes after initial versus redo paraesophageal hernia (PEH) repair at two high-volume GI surgery centers. MATERIALS AND METHODS: Retrospective review analyzed one-year outcomes after initial versus redo elective laparoscopic PEH repair, including wound/non-wound-related complications and quality of life benefits as measured by four validated instruments: reflux symptom index, gastroesophageal reflux disease health-related, laryngopharyngeal reflux, and swallowing scales. RESULTS: Three hundred and seventeen patients (271 initial and 46 redo) underwent laparoscopic PEH repair. Groups differed with respect to age (64.6 vs. 60.2 years, p = 0.027), but were comparable in gender (71.2 vs. 67.4% female, p = 0.596), BMI (29.0 vs. 27.6 kg/m2, p = 0.100), and ASA score (2.3 vs. 2.3 p = 0.666). Redo surgery was more complex with longer mean operative times (112.2 vs. 139.1 min, p < 0.001). Groups did not statistically differ with respect to 30-day wound (0.7 vs. 2.2%, p = 0.363) and non-wound (6.0 vs. 8.7%, p = 0.511)-related complications. After one year of follow-up, QOL analysis revealed that initial versus redo groups significantly benefited from operative intervention. CONCLUSIONS: Although redo PEH repairs are more complex, patients enjoy equivalent operative outcomes and quality of life benefits compared to initial surgery lending support to the significance of surgeon experience and high-volume centers in optimizing outcomes.

Characterization of ascites in cardiac cirrhosis: the value of ascitic fluid protein to screen for concurrent cardiac cirrhosis.

Abstracts Objectives: Cardiogenic ascites has been well described regarding its pathophysiology and fluid characteristics in prior literatures. However, ascites in patients with cardiac cirrhosis has not been characterized as a separate entity despite its unique pathophysiology and clinical aspects. This study aims to describe the fluid profile of ascites of cardiac cirrhosis and explore the utility of ascitic fluid protein (AFP) to predict concurrent cardiac cirrhosis. METHODS AND MATERIALS: We retrospectively selected and reviewed samples from the patients with cardiogenic ascites with and without concurrent cardiac cirrhosis. Epidemiologic characters, serum laboratory values, and fluid characteristics were directly compared between the groups. RESULTS: We analyzed 20 samples of ascitic fluid from the patients of cardiac cirrhosis and compared with 48 samples of non-cirrhotic cardiac ascites. The AFP was significantly lower in patients with cardiac cirrhosis (3.66g/dl) as compared to non-cirrhotic patients (4.31g/dl, p < .01); while there was no difference in serum-ascites albumin gradient (1.48g/dl vs. 1.47g/dl, p = .95). AFP equal to or less than 4.3g/dl predicted cirrhosis with a sensitivity of 95% and negative likelihood ratio of 0.10; the corresponding ROC curve of AFP has an AUC of 0.777, higher than AUC of other noninvasive prediction models. CONCLUSIONS: We presented the first fluid characterization of ascites in patients with cardiac cirrhosis. AFP was significantly lower than that from non-cirrhotic cardiac ascites, likely secondary to decreased serum protein level. AFP equal to or less than 4.3g/dl could be utilized to screen for concurrent cardiac cirrhosis with high sensitivity in patients with cardiogenic ascites without other predisposing factors for liver injury.

A Nationwide Study of the Impact of Dysphagia on Hospital Outcomes Among Patients With Dementia.

OBJECTIVES: To assess the impact of dysphagia on clinical and operational outcomes in hospitalized patients with dementia. DESIGN: Retrospective cohort study. SETTING: 2012 Nationwide Inpatient Sample. PARTICIPANTS: All patients discharged with a diagnosis of dementia (N = 234,006) from US hospitals in 2012. MEASUREMENTS: Univariate and multivariate regression models, adjusting for stroke and patient characteristics, to assess the impact of dysphagia on the prevalence of comorbidities, including pneumonia, sepsis, and malnutrition; complications, including mechanical ventilation and death; and operational outcomes, including length of stay (LOS) and total charges for patients with dementia. RESULTS: Patients having dementia with dysphagia (DWD) had significantly higher odds of having percutaneous endoscopic gastrostomy placement during the admission (odds ratio [OR]: 13.68, 95% confidence interval [CI]: 12.53-14.95, P < .001), aspiration pneumonia (OR: 6.27, 95% CI: 5.87-6.72, P < .001), pneumonia (OR: 2.84, 95% CI: 2.67-3.02, P < .001), malnutrition (OR: 2.5, 95% CI: 2.27-2.75, P < .001), mechanical ventilation (OR: 1.69, 95% CI: 1.51-1.9, P < .001), sepsis (OR: 1.52, 95% CI: 1.39-1.67, P < .001), and anorexia (OR: 1.29, 95% CI: 1.01-1.65, P = .04). Mean LOS was 2.16 days longer (95% CI: 1.98-2.35, P < .001), mean charge per case was US$10,703 higher (95% CI: US$9396-US$12,010, P < .001), and the odds of being discharged to a skilled nursing, rehabilitation, or long-term facility was 1.59 times higher (95% CI: 1.49-1.69, P < .001) in the DWD cohort compared to patients having dementia without dysphagia. CONCLUSION: Dysphagia is a significant predictor of worse clinical and operational outcomes including a 38% longer LOS and a 30% increase in charge per case among hospitalized patients with dementia. Although these findings may not be surprising, this new evidence might bring heightened awareness for the need to more thoughtfully support patients with dementia and dysphagia who are hospitalized.
