A Rare Case of Gastric Outlet Obstruction With Severe Reflux Esophagitis Due to a Percutaneous Endoscopic Gastrostomy Tube Balloon Displacement

In patients with a functional gastrointestinal (GI) tract, enteral feeding is preferred over parenteral feeding as it has fewer complications and a relatively lower cost. Nasogastric and nasoenteric feeding tubes are available options but when long-term enteral feeding is desired, a percutaneous endoscopic gastrostomy (PEG) tube is more convenient. PEG tube can be associated with multiple complications; however, its displacement which causes gastric outlet obstruction (GOO) is a rare one. Here we present a case of an 81-year-old woman with dementia who presented with upper GI bleeding and was found to have GOO causing reflux esophagitis due to PEG tube displacement

Pre-Diagnosis Aspirin Use Has No Effect on Overall Survival in Patients With Colorectal Cancer: A Study of a Multi-Racial Population

Introduction Aspirin has been associated with a reduction in mortality in patients diagnosed with colorectal cancer (CRC). A possible mechanism for this is related to the programmed cell death 1 (PD-1) immune checkpoint pathway. Aspirin may have a synergistic effect with PD-1 inhibitors via inhibition of prostaglandin E2 (PGE2) production, which can reverse the ability of tumor cells to evade the immune system. This appears to be strongest in cancers that express PI3 kinase (PI3K) signaling activity, which aspirin downregulates. However, the benefit of pre-diagnosis aspirin use on CRC overall survival (OS) and cancer-specific survival is still controversial, and most studies have been performed in racially homogenous populations. Our study examines the effect of pre-diagnosis aspirin therapy on OS in a racially diverse group of patients with CRC. Methods This is a retrospective chart review of 782 patients diagnosed with CRC from January 2007 to December 2020. Kaplan-Meier curve was created to study the association of aspirin exposure compared to no exposure on OS. In addition, univariate and multivariate binary logistic regression analyses were done to investigate potential predictors of survival. Results Of the 782 patients with CRC, 55.1% were males, 22.2% whites, 58.5% Asians, and 17.7% Pacific-Islanders. Moreover, 38.4% of the patients had a history of aspirin use, 79% of them used it for more than one year. There were more patients with hypertension (HTN), hyperlipidemia (HLD), diabetes mellitus (DM), and chronic kidney disease (CKD) among those with a history of aspirin use. There was no difference in one, three, and five-year OS among aspirin users compared to non-users, p-value = 0.63. Age, grade, and stage were potential predictors of worsened OS. However, treatment with chemotherapy and CKD were potential predictors of worsened OS on univariate analysis only. No significant association was noticed with gender, tumor location, or other associated comorbidities. Conclusion The effect of pre-diagnosis aspirin use on CRC survival is not clear. In this retrospective analysis of a racially diverse population of CRC patients, we found that aspirin use was not associated with improved OS. Therefore, physicians should be careful about using aspirin as adjuvant therapy in CRC patients until high-quality prospective data are available, given the potential associated complications

Clinical Characteristics and Outcomes of Decompensated Cirrhosis Patients Admitted to Hospitals With Acute Pulmonary Embolisms: A Nationwide Analysis

INTRODUCTION: Cirrhosis is a significant cause of mortality and morbidity worldwide. Recent studies suggested that cirrhosis is associated with an increased risk of venous thromboembolism (VTE), which disproves the old belief that chronic liver disease coagulopathy is considered protective against VTE. We conducted a retrospective study which is to our knowledge the first of its kind to assess clinical characteristics and outcomes of decompensated cirrhosis (DC) patients admitted with acute pulmonary embolism (APE). METHODOLOGY: We used the National Inpatient Sample database for the years 2016-2019. All adults admitted to the hospitals with a primary diagnosis of APE were included. Patients less than 18 years old, missing race, gender, or age were excluded. Patients were divided into two groups, either having DC or not. A multivariate logistic regression model was built by using only variables associated with the outcome of interest on univariable regression analysis at P \u3c 0.05. RESULTS: 142 million discharges were included in the NIS database between the years 2016 and 2019, of which 1,294,039 met the study inclusion criteria, 6,200 patients (0.5%) had DC. For adult patients admitted to the hospitals with APE, odds of inpatient all-cause mortality were higher in the DC group than in patients without DC; OR of 1.996 (95% CI, 1.691-2.356, P-value \u3c 0.000). Also, vasopressor use, mechanical ventilation, and cardiac arrest were more likely to occur in the DC group, OR of 1.506 (95% CI, 1.254-1.809, P-value \u3c 0.000), OR of 1.479 (95% CI, 1.026-2.132, P-value 0.036), OR of 1.362 (95% CI, 1.050-1.767, P-value 0.020), respectively. In addition, DC patients tend to have higher total hospital charges and longer hospital length of stay, coefficient of 14521 (95% CI, 6752-22289, P-value \u3c 0.000), and a coefficient of 1.399 (95% CI, 0.848-1.950, P-value \u3c 0.000), respectively. CONCLUSION: This study demonstrates that DC is a powerful predictor of worse hospital outcomes in patients admitted with APE. An imbalance between clotting factors and natural anticoagulants produced by the liver is believed to be the primary etiology of thrombosis in patients with DC. The burden of APE can be much more catastrophic in cirrhotic than in non-cirrhotic patients; therefore, those patients require closer monitoring and more aggressive treatment

Post-Endoscopic Retrograde Cholangiopancreatography Pancreatitis: What We Already Know

Acute pancreatitis is the most common serious complication of endoscopic retrograde cholangiopancreatography (ERCP) resulting in significant morbidity and occasional mortality. Post-ERCP pancreatitis (PEP) has been recognized since ERCP was first performed, and many studies have shown a consistent risk that must be balanced against the many benefits of this procedure. This review will discuss the pathogenesis, epidemiology, potential risk factors, and clinical presentation of PEP. Moreover, it will discuss in detail the most recent updates of PEP prevention and management

The Relationship Between Obstructive Sleep Apnea (OSA) and Gastroesophageal Reflux Disease (GERD) in Inpatient Settings: A Nationwide Study

INTRODUCTION: Several studies identified a link between gastroesophageal reflux disease (GERD) and obstructive sleep apnea (OSA). GERD is a condition in which acid reflux from the stomach to the esophagus causes troublesome symptoms. On the other hand, OSA is defined as a sleep-related breathing disorder in which airflow significantly decreases or ceases due to upper airway obstruction, leading to arousal from sleep. OSA was found to be associated with GERD. In this study, we aim to study the characteristics and concurrent risk factors associated with GERD and OSA in a large population-based study. METHODS: Patients with the diagnosis of GERD were extracted from the National Inpatient Database (NIS) for the years 2016 to 2019. Patients\u27 age, gender, race, and hospital information, including region and bed size, were extracted and considered as baseline characteristics. The comorbidities included are hypertension (HTN), atrial fibrillation (AFib), congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), pulmonary hypertension (PHTN), obesity, and smoking. Patients younger than 18 years old were excluded from this study. Results: Out of 22,677,620 patients with the diagnosis of GERD, 12.21% had a concurrent diagnosis of OSA (compared to 4.79% in patients without GERD, p-value \u3c0.001). The mean age of patients with GERD and OSA was 64.47 years vs 65.42 years in patients without OSA (p-value \u3c0.001). The GERD and OSA group had almost identical gender distribution compared to the GERD only group, as it was predominantly female patients. The white and black races were slightly more prevalent in the GERD and OSA group compared to the GERD only group. Regarding comorbidities, the prevalence of obesity was more clear in the GERD and OSA group. It was noted that the group of patients who carry a diagnosis of GERD and OSA have more prevalence of diabetes (DM), hypertension (HTN), obesity, atrial fibrillation (Afib), congestive heart failure (CHF), and pulmonary hypertension (PHTN). Patients with GERD and OSA were 21% less likely to be older than 65 years rather than younger (95% CI: 0.79-0.8, p-value \u3c0.001), 35% less likely to be females (95% CI: 0.65-0.65, p-value \u3c0.001), and 22% less likely to be non-white (95% CI: 0.77-0.8, p-value \u3c0.001). Obesity was found to be the strongest association with this population, followed by PHTN, CHF, DM, HTN, Afib, and lastly smoking. CONCLUSION: Patients with GERD and OSA were found more likely to be female, white, living in the southern part of the United States, obese, diabetes mellitus type 2, and being active smokers

Pancreatic surgery outcomes: multicentre prospective snapshot study in 67 countries

Background: Pancreatic surgery remains associated with high morbidity rates. Although postoperative mortality appears to have improved with specialization, the outcomes reported in the literature reflect the activity of highly specialized centres. The aim of this study was to evaluate the outcomes following pancreatic surgery worldwide.Methods: This was an international, prospective, multicentre, cross-sectional snapshot study of consecutive patients undergoing pancreatic operations worldwide in a 3-month interval in 2021. The primary outcome was postoperative mortality within 90 days of surgery. Multivariable logistic regression was used to explore relationships with Human Development Index (HDI) and other parameters.Results: A total of 4223 patients from 67 countries were analysed. A complication of any severity was detected in 68.7 percent of patients (2901 of 4223). Major complication rates (Clavien-Dindo grade at least IIIa) were 24, 18, and 27 percent, and mortality rates were 10, 5, and 5 per cent in low-to-middle-, high-, and very high-HDI countries respectively. The 90-day postoperative mortality rate was 5.4 per cent (229 of 4223) overall, but was significantly higher in the low-to-middle-HDI group (adjusted OR 2.88, 95 per cent c.i. 1.80 to 4.48). The overall failure-to-rescue rate was 21 percent; however, it was 41 per cent in low-to-middle-compared with 19 per cent in very high-HDI countries.Conclusion: Excess mortality in low-to-middle-HDI countries could be attributable to failure to rescue of patients from severe complications. The authors call for a collaborative response from international and regional associations of pancreatic surgeons to address management related to death from postoperative complications to tackle the global disparities in the outcomes of pancreatic surgery (NCT04652271; ISRCTN95140761)
