End-stage renal disease and lower gastrointestinal bleeding-A propensity-matched analysis of nationwide inpatient sample.

AIMS: We aim to determine the influence of lower gastrointestinal bleeding (LGIB) on mortality, morbidity, length of hospital stay and resource utilisation in end-stage renal disease (ESRD) patients. MATERIAL AND METHODS: The National Inpatient Sample database (2016 &2017) was used for data analysis using the International Classification of Diseases, Tenth Revision codes to identify the patients with the principal diagnosis of ESRD and LGIB. We assessed the all-cause in-hospital mortality, morbidity, predictors of mortality, length of hospital stay (LOS) and total costs between propensity-matched groups of ESRD patients with LGIB versus ESRD patients. RESULTS: We identified 2 187 954 ESRD patients, of whom 242 075 has LGIB, and 1 945 879 were ESRD patients. The in-hospital mortality was higher in ESRD with LGIB (OR 2.5, 95% CI 1.5-2.2; P = .00). ESRD with LGIB has higher odds of mechanical ventilation (OR 1.4, 95% CI 6.4-16.4; P = .00), and shock requiring vasopressor (OR 1.2, 95% CI 4.9-5.4; P = .002). Advanced age (OR 1.02 CI 1.02-1.03 P = .00), anaemia (OR 1.04 CI 1.59-1.91 P = .006), acute coronary syndrome (OR 1.8 CI 1.6-2.1, P = .00), acute respiratory failure (OR 1.29 CI 2.0-2.6, P = .00), mechanical ventilation (OR 1.9, CI 3.5-4.4, P = .00) and sepsis (OR 1.5, CI 4.1-5.08, P = .00) were identified as predictors of mortality in ESRD with LGIB. Mean LOS (10.8 ± 14.9 vs 6.3 ± 8.5, P < .01) and mean total charges (37 054 $ vs 18 080 $, P < .01) were also higher. CONCLUSIONS: In this propensity-matched analysis, ESRD with LGIB was associated with higher odds of in-hospital mortality, mechanical ventilation and shock requiring vasopressor. Mean LOS and resource utilisation were also higher.

The Incidence and Outcomes of Venous Thromboembolisms in Patients Admitted with Different Gastrointestinal Malignancies.

Introduction: Venous thromboembolism (VTE) is associated with significant morbidity and mortality in cancer patients. Our study compares the mortality in hospitalized VTE patients among the four most common gastrointestinal (GI) malignancies which include esophageal, gastric, pancreatic, and colorectal cancer. Methods: A retrospective study was conducted utilizing the Nationwide Inpatient Sample database (NIS) from 2016 to 2019. Patients with VTE were identified using ICD-10 codes from all primary discharge diagnoses. Only deep venous thrombosis (DVT) and pulmonary embolism (PE) were considered. Patients with VTE were further divided into groups: esophageal cancer, gastric cancer, pancreatic cancer, and colorectal cancer, and compared with patients who did not have these malignancies. The adjusted odds ratio (aOR) was calculated using multivariate regression analysis. Results: Among 999,559 patients discharged with a VTE diagnosis, 25,775 (2.6%) had one of the four GI malignancies. Among patients with one of the four included GI malignancy diagnosis, 18,816 (73%) patients had PE and 6,959 (27%) patients had DVT. The study shows that adults admitted to the hospitals for VTE have higher mortality when compared to patients who did not have GI malignancies, with esophageal cancer having the highest inpatient mortality with an aOR of 2.701; 95% confidence interval (CI) 1.989-3.669, p value <0.000. For the remaining GI cancers, gastric cancer had an aOR 1.576; CI: 1.094-2.269, p value 0.015, and pancreatic cancer had an aOR of 1.736; 95% CI: 1.445-2.085, p value <0.000. Patients with colorectal cancer had no significant increase in the odds of mortality with aOR of 1.213; 95% CI: 0.988-1.489, p value 0.066. Conclusions: This study demonstrates that VTE in hospitalized patients with esophageal cancer is associated with greater mortality compared to other GI malignancies.

Type A Aortic Dissection Presenting as Acute Coronary Syndrome in a Young Male Patient: A Case Report.

Type A aortic dissection (AD) is a devastating cardiovascular emergency requiring emergent surgical intervention. Most patients with AD have several risk factors for the disease including longstanding hypertension, smoking history, atherosclerosis, and old age. Younger patients may also present with AD if a genetic disorder affecting the integrity of the aorta is present. This case presents an otherwise healthy 36-year-old male with no known significant family history who presented with an atypical presentation of aortic dissection. He described a five-day history of chest pressure made worse with exertion followed by progressive dyspnea which prompted him to seek medical attention. His initial laboratory workup revealed an elevated troponin I level which prompted a cardiology consultation in the emergency department. Transthoracic echocardiography revealed dilatation of the aortic root and aortic regurgitation. CT angiography of the chest was performed revealing a type A dissection beginning at the aortic root and terminating proximal to the right brachiocephalic artery. Involvement of the coronary arteries was suspected due to the elevated troponin I. He was taken to the operating room and underwent aortic grafting, right coronary artery bypass, and repair of the left main artery. Unfortunately, at the end of the operation, the patient went into refractory ventricular fibrillation, which progressed to asystole. He was unable to be revived.

Massive Upper Gastrointestinal Bleeding Following LAMS (Lumen-Apposing Metal Stent) Placement.

Pancreatic pseudocyst is a common complication of pancreatitis. Pseudocysts may require decompression when they become painful, infected, or start compressing surrounding organs. Decompression is achieved by endoscopic cystogastrostomy. Recently, the use of lumen-apposing metal stent (LAMS) for cystogastrostomy has gained popularity due to ease of use and high technical success. LAMS has a wider lumen, which allows for direct endoscopic necrosectomy in the cases of walled-off necrosis. Our patient is a 30-year-old male who presented with massive hematemesis and dizziness. He had a history of chronic alcohol-induced pancreatitis. Three weeks before the presentation, he underwent a cystogastrostomy with LAMS placement to treat a 10-cm walled-off necrosis. Urgent computed tomography (CT) scan did not reveal any acute finding suggestive of bleeding. Esophagogastroduodenoscopy showed blood protruding from the LAMS with a large clot formation. Attempts to stop bleeding were unsuccessful. He underwent CT angiography of the abdomen. CT angiography showed a bleeding pseudoaneurysm (PA) believed to be a complication of the LAMS. Subsequently, multiple coils were placed in the splenic artery near the PA. The patient continued to improve without a further drop in hemoglobin and was eventually discharged. PA formation and subsequent rupture is a rare delayed complication of LAMS. It may lead to massive gastrointestinal bleeding with a high mortality rate. Diagnostic delays have resulted in increased mortality by 60%. In this article, we present a case of massive gastrointestinal bleeding due to a ruptured splenic artery PA presenting as a delayed complication of LAMS.

Dolosigranulum pigrum: Predicting Severity of Infection.

In this report, we describe a case of a 61-year-old male patient who had the bacterium Dolosigranulum pigrum growing in a blood culture. It was susceptible to ampicillin, ceftriaxone, levofloxacin, and vancomycin but was intermediately resistant to erythromycin. The patient did not have a negative outcome as a consequence of this bacterium, which retrospectively could have been predicted based on the epidemiological data within the patient's profile.
