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

Direct-Acting Antivirals in Chronic Hepatitis C Infection with Liver Cirrhosis

Chronic hepatitis C infection is a common cause of liver morbidity and mortality across the world, in part due to complications including cirrhosis and hepatocellular carcinoma. The advent of Direct-acting antiviral (DAA) therapy has the potential to change the outcome of HCV infection in the vast majority of patients. Unfortunately, the chronic nature of HCV infection means that many patients requiring direct-acting antiviral (DAA) therapy have already developed compensated cirrhosis. This chapter reviews the importance of DAAs in the treatment of HCV infection, particularly in patients with existing compensated cirrhosis. Both efficacy and safety are discussed as essential endpoints of DAA therapy. Decompensated cirrhosis, treatment failures, vitamin-D deficiency, HIV co-infection, and ethnic differences in the context of treatment response are also discussed in this chapter

Liver Assist Devices for Liver Failure

Historically, mortality rates for liver failure have been high, regardless of the type. With new advancements in liver transplantation (LTx), 1-year survival rates have improved up to 95% in most recent estimates. While some patients may live past the critical period, the majority of patients do not survive the interval period for awaiting LTx or liver regeneration. The function of the liver to detoxify and correct several biochemical parameters has been achieved to some extent through artificial liver support technology, although constant innovations are still being developed for the most optimal liver support device. The complex function of the liver makes it challenging since it does not only detoxify toxic by-products but also participates in numerous other synthetic and metabolic functions of the body. Liver support systems are divided into an artificial liver assist device (ALD) and a bioartificial liver assist device (BLD). ALDs include molecular adsorbent recirculating system (MARS), Prometheus, single-pass albumin dialysis, and selective plasma filtration therapy. These devices work as a blood purification system of the liver. On the other hand, BLD has hepatic cell lines incorporated in its equipment, which aims to function as a complex biological liver system providing support to its biochemical processes. Several clinical and randomized trials have conflicting results on the survival of the patients with acute liver failure (ALF), and the ideal liver support system still seems a far-off goal

Co-infection with Influenza A and COVID-19

COVID-19, also called severe acute respiratory distress syndrome coronavirus 2 (SARS-CoV-2), originated in Wuhan, China. It has caused significant morbidity and mortality worldwide and has been declared a global pandemic by the WHO. Influenza occurs mainly during the winter, with the burden of disease determined by several factors, including the effectiveness of the vaccine that season, the characteristics of the circulating viruses, and how long the season lasts. We describe the case of a 66-year-old woman who was diagnosed with influenza A and COVID-19 co-infection

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 \u3c.01) and mean total charges (37 054 $vs 18 080$, P \u3c.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

Early Detection of Colon Cancer Following Incidental Finding of Bacteremia

Clostridium septicum is a Gram-positive, anaerobic, spore-forming bacillus found in the intestine. It is linked to colon cancer and immunosuppression. Infection with C septicum may vary in manifestation and is associated with more than 60% mortality rate. In this article, we present a case of incidental isolation of C septicum in a patient who presented with fever and later on colonoscopy was found to have colon carcinoma. Bacteremia may be the unexpected initial presentation of undiagnosed colon carcinoma

Moderate Hypertriglyceridemia Causing Recurrent Pancreatitis: A Case Report and the Literature Review

Recurrent acute pancreatitis secondary to hypertriglyceridemia (HTG) with levels below 1000 mg/dL has been rarely reported in the literature. HTG is the third most common cause of acute pancreatitis and has been established in the literature as a risk factor when levels are greater than 1000 mg/dL. A 43-year-old patient presented to the hospital with severe epigastric abdominal pain. Initial laboratory investigations were significant for a lipase level of 4143 U/L and a triglyceride level of 600 mg/dL. Computed tomography (CT) of the abdomen showed diffuse enlargement of the pancreas consistent with pancreatitis. A diagnosis of severe acute pancreatitis secondary to high triglycerides was made based on the revised Atlanta classification 2012. The patient was initially managed with intravenous boluses of normal saline followed by continuous insulin infusion. Diabetic Ketoacidosis (DKA) was ruled out due to a past medical history of diabetes. Her clinical course was complicated by acute respiratory distress syndrome requiring intubation and mechanical ventilation. During the course, she improved symptomatically and was extubated. She was started on nasogastric feeding initially and subsequently switched to oral diet as tolerated. After initial management of HTG with insulin infusion, oral gemfibrozil was started for long-term treatment of HTG. Emerging literature implicates HTG as an independent indicator of poor prognosis in acute pancreatitis (AP). Despite the paucity of data, the risk of developing AP must be considered even at triglyceride levels lower than 1000 mg/dL
