The Utility of the Platelet-Albumin-Bilirubin Score as a Non-invasive Predictor of Esophageal Varices and Variceal Hemorrhage in Patients With Liver Cirrhosis Compared to Child-Turcotte-Pugh and Model of End-Stage Liver Disease-Sodium Scores.

Introduction Research on non-invasive tools for detecting gastro-esophageal varices is underway. We investigated the Platelet-Albumin-Bilirubin (PALBI) score in comparison with the Child-Turcotte-Pugh (CTP) and MELD-Na (MELD-Na) scores in patients with liver cirrhosis. Methods Three hundred and twenty-three patients with liver cirrhosis were studied. The PALBI, CTP and MELD-Na scores were calculated and analyzed for gastroesophageal varices and their characteristics using SPSS version 26 (IBM Corp., Armonk, NY, USA). Results Two hundred and sixty-four patients had esophageal varices and 102 presented with variceal hemorrhage. Mean PALBI, CTP and MELD-Na scores were significantly higher for patients with varices versus without varices (p < 0.05). Unlike the mean MELD-Na score, the mean PALBI and CTP scores were significantly higher in patients with large high-risk varices as compared to patients with small low-risk varices (p < 0.05). The mean CTP scores were significantly higher in patients with variceal hemorrhage than those without hemorrhage (p < 0.05), while the difference between mean PALBI and MELD-Na was insignificant, in this regard. The PALBI score had better sensitivity than the CTP and MELD-Na scores in indicating the presence of varices but was similar to the CTP score in predicting high-risk varices. Conclusion The PALBI score proves to have good utility and efficiency in predicting varices in comparison to CTP and MELD-Na scores. It can determine high-risk stigmata of variceal hemorrhage with similar performance as the CTP Score.

When Two Syndromes Collide: Managing Fanconi and Refeeding Syndrome in a Single Patient.

Refeeding syndrome is the potentially fatal shift in fluids and electrolytes that may occur in malnourished patients after receiving artificial refeeding. Its hallmark feature is hypophosphatemia, although other electrolytes might also be affected. Fanconi syndrome is a generalized dysfunction of the proximal tubule characterized by proximal renal tubular acidosis (RTA), phosphaturia, glycosuria, aminoaciduria, and proteinuria. The etiology of Fanconi syndrome can be either acquired or inherited, and drugs, among them tenofovir, are a common acquired cause of this disease. We present the case of a patient with AIDS and polysubstance abuse who was admitted due to pneumonia, completed treatment, was then started on antiretroviral medication (ART) that included tenofovir alafenamide (TAF) and began presenting severe episodes of hypophosphatemia along with other electrolyte imbalances, leading the workup denoted in the case, severe complications and finally to the patient's demise. Most cases of tenofovir-related Fanconi syndrome are related to tenofovir disoproxil fumarate, but very few cases have been reported with TAF. Our case highlights this rare complication of therapy with TAF and how artificial feeding can contribute to severe electrolyte abnormalities and worsen outcomes.

The Role of Endoscopy in Investigating the Causes of Persistent Anaemia in Post-operative Fractured Neck of Femur Patients.

Introduction Post-operative anaemia in hip fracture patients has been associated with increased risk of blood transfusion, poorer functional outcomes, increased morbidity and mortality. Patients with persisting drop in haemoglobin after fractured neck of femur with no obvious source of blood loss are often referred for endoscopy to find the cause of anaemia. The reported incidence of perioperative acute upper gastrointestinal bleeding varies from 1 to 15%. Objective The aim of our study is to find out the usefulness of endoscopy in finding gastrointestinal causes leading to the occult loss of blood causing irreversible anaemia in post-operative neck of femur fractures. Material and methods The orthogeriatric unit conducted a study using retrospective data on neck of femur fracture patients from January 2015 to December 2020. Out of 1863 cases, 918 (49.3%) developed post-operative anaemia. Forty-five patients (5%) with refractory anaemia underwent endoscopy referral. Patient demographics, fracture patterns, pre-existing anaemia, and co-morbidities (anaemia, heart disease, chronic kidney disease, oral anticoagulant usage) were recorded. The recorded information also included the type of procedure undergone by each patient. Intra-operative tranexamic acid injections were administered to all patients. Results Male patients accounted for 24% (11) and females for 76% (34). The average age was 82.3 years (range: 73-94). In terms of fracture type, 60% (27) were intracapsular and 40% (18) were extracapsular. Iron deficiency anaemia was present in 24% (11), oral anticoagulants in 20% (9), and systemic malignancy in 12% (6) of patients. The mean post-operative hemoglobin level during endoscopy referral was 7.3 g/dL. Endoscopy revealed normal findings in 60% (27), esophagitis/gastritis in 20% (8), and hiatus hernia in 16% (7) of patients. No patients were diagnosed with active gastrointestinal bleeding or malignancy as the cause of post-operative hemoglobin drop. Conclusion The study did not show evidence of any gastrointestinal bleeding in patients with resistant and refractory post-operative anaemia following fractured neck of femur surgery using endoscopy procedure. The value of such difficult, expensive and time-consuming procedure may be reviewed further.

Isolated Proximal Black Esophagus in a COVID-19 Patient.

Black esophagus or acute esophageal necrosis (AEN) is a rare cause of upper gastrointestinal (UGI) bleeding usually involving distal esophagus. Proximal esophageal involvement is quite rare. We present an 86-year-old female with active coronavirus disease 2019 (COVID-19) infection who came in with newly diagnosed atrial fibrillation and was started on anticoagulation. She subsequently developed a UGI bleed, which was complicated by inpatient cardiac arrest. Following resuscitation and stabilization, UGI endoscopy showed circumferential black discoloration of proximal esophagus, with distal esophageal sparing. Conservative management was instituted and fortunately, repeat UGI endoscopy two weeks later showed improvement. This describes the first case of isolated proximal AEN in a COVID-19 patient.

Mucosa-Associated Lymphoid Tissue Lymphoma Masked as Gastric Varices With Acute Upper Gastrointestinal Bleeding: A Case Report.

Extra-nodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) is uncommon and difficult to diagnose due to varied clinical presentations and endoscopic appearances masquerading as other pathology. Rarely, it has been associated with acute upper gastrointestinal (GI) bleeding. We report on a 60-year-old male who presented with an acute upper GI bleed and endoscopic findings suggestive of isolated gastric varices (GV), ultimately determined to be MALT lymphoma. Complete remission was achieved with radiation therapy, with no recurrence at a 12-month follow-up. This case highlights a unique clinical and endoscopic presentation of MALT lymphoma which providers should be aware of. We emphasize the use of endoscopic ultrasound (EUS) evaluation for accurate diagnosis.

Gastric Outlet Obstruction Caused by a Duodenal Clot.

Gastric outlet obstruction (GOO) is a mechanical obstruction usually located in the gastric pylorus or duodenum. After the introduction of proton pump inhibitors (PPIs) in the late 1980s, most cases of gastric outlet obstruction are now caused by malignancy and peptic ulcer disease rarely leads to obstruction. We present a case of GOO caused by a large clot in the pylorus, preventing visualization of the source of bleeding. As the removal of the obstructing clot was deemed too high risk, the patient was treated with promotility agents that relieved the obstruction and allowed for the identification of the etiology of his upper gastrointestinal bleeding. Bleeding was definitively managed with embolization of the gastroduodenal artery.

Necrotizing Pancreatitis: To Anticoagulate or Not to Anticoagulate?

Necrotizing pancreatitis is an inflammatory process that poses a strong risk of systemic venous thromboembolism. However, it is often challenging to opt for systemic anticoagulation since the disease is also associated with an increased risk of hemorrhage. Given these opposing complications, a risk versus benefit analysis has to be employed in the management of necrotizing pancreatitis on a case-by-case basis. We discuss a case where the team was faced with a dilemma regarding anticoagulation in a patient with newly developed atrial fibrillation in the setting of necrotizing pancreatitis. We found that there is a lack of guidelines that address the time of initiation and the type of systemic anticoagulation that should be administered in such patients.

Should we routinely prescribe proton pump inhibitors peri-operatively in elderly patients with hip fractures? A review of the literature.

Elderly hip fracture patients are at risk of stress-related gastric mucosal damage, and upper gastrointestinal bleeding is one of the underrecognized but devastating complications.Proton pump inhibitors (PPIs) offer effective prophylaxis against stress-related gastric mucosal damage.Systematic analysis of the literature revealed numerous articles on PPIs and hip fractures, but only three articles dedicated to the analysis of prophylactic use of PPIs in patients with a hip fracture.There is significant reduction in upper gastrointestinal bleeding following PPI prophylaxis and reduced 90-day mortality in elderly hip fracture patients on prophylaxis.PPIs are generally safe, cost-effective and based on available evidence. Their prophylactic use is justifiable in elderly patients with hip fractures.We suggest that PPIs be prescribed routinely peri-operatively in elderly hip fracture patients. Further level-one studies on the subject will allow for firmer recommendations. Cite this article: EFORT Open Rev 2021;6:686-691. DOI: 10.1302/2058-5241.6.200053.

A Benign Ulcerating Gastric Mass Presenting as Acute Gastrointestinal Hemorrhage.

Gastrointestinal lipomas are rare, often colonic tumors. The stomach is an unusual site of involvement of lipomas, accounting for less than 5% of all gastrointestinal lipomas and less than 3% of all benign gastric neoplasms. They are usually asymptomatic, and symptoms develop as the tumor grows. Gastric lipomas can present with massive bleeding from an ulcerating tumor and can be life-threatening if left untreated. We present a case of an ulcerating gastric lipoma that presented as an acute upper gastrointestinal hemorrhage. The patient was treated with Billroth II procedure and final pathology showed an ulcerating submucosal lipoma. The diagnosis of gastric lipoma is often suspected incidentally on imaging, then confirmed via biopsy. Definitive treatment of large lesions typically requires surgery, however, newer endoscopic techniques are being utilized for resection of these benign tumors.

Proton Pump Inhibitors: Exploring Cardiovascular Complications and Prescription Protocol.

Proton pump inhibitors (PPIs) are among the most extensively prescribed medications internationally for gastroesophageal reflux disease treatment and the prevention of gastrointestinal bleeding. Their efficiency, ease of availability, and low side effect profile offer several advantages over other treatment modalities. Long-term use and inappropriate prescribing habits have increased the presence of this class of drugs, prompting several studies to reassess their adverse effects. This article explored the possibility of a relationship between PPIs and cardiovascular adverse effects while highlighting the current prescription guidelines for PPIs. We further examined the need for more research into the etiology of PPI-related cardiovascular adverse effects and strategies to alleviate these risks.

Late Manifestation of Massive Jejunal and Cecal Varices Post Liver and Small Bowel Transplantation in a Patient With Microvillus Inclusion Disease.

We report the case of an 18-year-old male with a medical history of microvillous inclusion disease (MID) and notable surgical history of small bowel, liver, and pancreas transplant who presented with massive jejunal and cecal varices. Endoscopy findings demonstrated a large grape-like cluster, with subsequent CT angiography (CTA) showing other variceal lesions in the cecum. The patient was transferred to the original transplant center for recommended open surgical evaluation and combined interventional radiology (IR) embolization of varices. MID is a rare genetic disorder caused by mutations in the Myosin VB (MYO5B) gene leading to a lack of myosin Vb. Patients subsequently develop liver damage at birth, which necessitates a small bowel/liver transplant in childhood.

Strongyloides Hyperinfection Causing Gastrointestinal Bleeding and Bacteremia in an Immunocompromised Patient.

Strongyloidiasis is a parasitic infestation caused by Strongyloides stercoralis (S. stercoralis). Most cases are asymptomatic or mildly symptomatic with respiratory, gastrointestinal, or non-specific cutaneous symptoms. However, in immunocompromised patients, such as patients on chronic corticosteroids, malignancy, or human immunodeficiency virus (HIV) infection, hyperinfection syndrome can occur. The following is a case of Strongyloides hyperinfection in an individual taking prednisone for uveitis who developed upper gastrointestinal (GI) bleed and gram-negative bacteremia.

A Rare Case of a Life-Threatening Massive Upper Gastrointestinal Bleed and Airway Obstruction in a Patient With a Megaesophagus Secondary to Longstanding Achalasia.

Achalasia is a relatively rare motor disorder characterized by esophageal aperistalsis and incomplete relaxation of the lower esophageal sphincter. In only 10% of patients, untreated or poorly managed achalasia can progress to esophageal dilation and eventual loss of total functionality resulting in a characteristic sigmoid dolichomegaesopahagus. In extremely rare instances, this sigmoid dolichomegaesopahagus can present clinically as acute airway obstruction or a fatal, life-threatening hemorrhage requiring immediate intervention. We present the case of a 65-year-old female with a past medical history of long-standing achalasia who had complaints of shortness of breath, chest pain, and two episodes of life-threatening hematemesis requiring a blood transfusion. An angiography illustrated significant distention of the esophagus occupying most of the right hemithorax and non-specific intraluminal fluid with a small amount of gas. Emergent esophagogastroduodenoscopy showed fibrosis and necrosis of the esophageal mucosa with food debris, suggesting that the bleeding was likely coming from an ulcer caused by pressure necrosis. The patient was hemodynamically unstable after the procedure and was transferred to another facility the next day for an esophagectomy. Patients with achalasia have an increased susceptibility to develop pressure ulcers due to increased shear force on the esophageal wall, increased moisture of the esophageal wall from prolonged contact of food boluses, and underlying malnutrition and weight loss from the indigestion of food causing atrophy of the mucosal barriers. The management of these ulcers is to treat and manage the underlying cause. Although there are no curative treatments for achalasia, symptomatic relief through both surgical and medical therapies are the mainstay of management, with an esophagectomy reserved for refractory cases or in patients who develop end-stage complications.

Delayed Recurrence of Chromophobe Renal Cell Carcinoma Presenting as Metastatic Duodenal Ulcer.

Renal cancers are one of the common causes of cancer-related morbidity and mortality worldwide. Most primary cases are localized at presentation and are treated with partial or radical nephrectomy with curative intent. However, renal cell carcinoma (RCC) is known for its potential recurrence, sometimes several years after initial management. Many of these recurrent cases commonly metastasize to the liver, kidney, or bone and herald a poor prognosis. We present a case study of nonclear cell RCC, which recurred 33 years after nephrectomy and masqueraded as a duodenal ulcer -- an extremely rare site for metastasis. This is unique as it describes a presentation only sparingly documented in the medical literature and highlights a more extended period of recurrence than currently reported. Moreover, our patient's tumor was chromophobe cell variety, a rare sub-type of nonclear cell RCC, which to our knowledge has never been known to cause duodenal metastasis. Studies have implicated a prognostic role of lymph node involvement at the time of initial diagnosis to predict future recurrence. This case is a drop in the mighty ocean to prompt further investigation on the utility of life-long surveillance protocols and further research evaluating the role of lymph node dissection in preventing such recurrences and high mortality.
