Efficacy and Safety of Variable Treatment Options in the Prevention of Hepatic Encephalopathy: A Systematic Review and Network Meta-Analysis

There are no guidelines for the most effective medication to reduce hepatic encephalopathy (HE) or the associated mortality. The purpose of this study is to determine the most effective possible treatment among the single treatment options or the combined treatment options for decreasing the morbidity and mortality of HE. We evaluated the outcomes by various parameters such as the quality of life, reduction in ammonia, all causes of mortality, adverse events, reversal of minimal HE, and development of overt HE. We systematically searched PubMed, Cochrane, Web of Science, and Scopus till the 19th of January 2023 for studies that assess various treatment options for HE. Data were extracted from eligible studies and pooled in a frequentist network meta-analysis as standardized mean difference (SMD) and their 95% confidence interval (CI) using the MetaInsight web-based tool. The Cochrane Tool was used to assess the randomized controlled trials' quality (RCT), while the NIH tool was used to assess the quality of the included cohort studies. Utilizing the R software, the network meta-analysis was conducted. In addition to a significant variation in cases of (Lactulose and Rifaximin) compared with Rifaximin (RR= 0.39, 95% CI [0.17; 0.89]), the results demonstrated a significantly lower incidence of overt HE in (Lactulose and Rifaximin) compared with placebo (RR=0.19, 95% CI [0.09; 0.40]). Most arms demonstrated a statistically significant reduction in the incidence of overt HE compared to albumin and placebo. The results also demonstrated a significant reduction in ammonia between L-ornithine-L-aspartate (LOLA) and probiotics (MD= -19.17, 95% CI [-38.01; -0.32]), as well as a significant difference in the incidence of LOLA compared to placebo (MD= -22.62, 95% CI [-39.16; -6.07]). This network meta-analysis has significant data for managing subclinical HE in people without a history of overt HE. Our analysis showed that (Lactulose and Rifaximin), followed by (Rifaximin and L-carnitine), followed by (Lactulose and Rifaximin with zinc) were the best combinations regarding overt HE. LOLA reduced ammonia best, followed by Nitazoxanide and finally Lactulose. (Lactulose and Nitazoxanide) have the least adverse effects, followed by (Rifaximin and L-carnitine), then Probiotics. Yet, all mortality outcomes and quality of life changes yielded no useful findings. Future studies like RCTs must be done to compare our therapies directly.

Physician-scientists or celebrities? Kardashian-index of gastroenterologists

BACKGROUND

The coronavirus disease 2019 pandemic unleashed a flood of untrustworthy information on social media platforms, resulting in the unfortunate consequence of expert scientists' opinions getting lost amidst the chaotic sea of misinformation. The question of how much influence these esteemed scientists hold on social media platforms remains elusive. To address this scientific quandary, we sought to explore the concept of the Kardashian index (K-index), a term introduced by Hall in 2014. This metric provides a rudimentary means of evaluating whether a physician scientist's popularity on social media aligns with their significant scientific contributions.

AIM

To evaluate if a Gastroenterologist physician's popularity on social media is at par with their scientific contributions (research articles and publications).

METHODS

We conducted an extensive search to identify all gastroenterologists actively practicing and associated with the top 100 hospitals as reported by the United States News. We collected specific data on a sub-group including their names, affiliations, degrees, and sub-specializations. To gauge their social media popularity, we utilized the K-index calculation which is determined by dividing the actual number of Twitter followers by the number of researcher's citations. The expected number of followers (F) is calculated using the formula F = 43.3 C ^ 0.32, where C represents the number of citations.

RESULTS

Physicians affiliated with the Mayo Clinic emerged as the most prominent presence on Twitter, constituting 16% of the total. They were followed closely by physicians from Mount Sinai Hospital (9%) and the University of Michigan Hospital (9%). Surprisingly, 76% of the physicians evaluated exhibited a low K-index, falling within the range of 0 to less than 2. This suggests that a significant number of highly influential physician-scientists are not receiving due recognition, as indicated by their relatively low number of followers. On the other hand, 24% of the physicians had an inflated K-index, exceeding 5, which positioned them as the "Kardashians". These individuals enjoyed greater social media popularity than their actual scientific contributions. Interestingly, our analysis revealed no discernible association between sex and K-index (P value of 0.92).

CONCLUSION

In the gastroenterology field, our study estimated that a majority (76%) of highly researched physicians are undervalued despite their significant scientific contributions.

Trends in Hospitalizations of Esophageal Varices From 2011 to 2018: A United States Nationwide Study

Background

Prevalence of gastroesophageal varices is around 50% of patients with cirrhosis. In compensated cirrhosis they are present in 30-40%. Progression from small to large varices occurs at rate of 10-12% annually. That percentage increases significantly in decompensated liver cirrhosis with gastroesophageal varices found in 85% of patients. Variceal hemorrhage occurs at a rate around 10-15% per year. The outcome of variceal hemorrhage depends on the severity of liver disease, size of varices, and presence of stigmata of recent bleeding (red whale sign). Six-week mortality of variceal hemorrhage ranges between 15% and 25%. Without treatment, variceal hemorrhage tends to recur in 60% of patients within 1 - 2 years. The aim of the study was to assess demographics of esophageal varices with and without bleeding, geographic distribution, comorbidities, outcomes, main payers, and cost of hospitalizations.

Methods

The National Inpatient Sample (NIS) database from year 2011 to 2018 was used. Patients who had a primary diagnosis of esophageal varices with or without bleeding were identified using the International Classification of Diseases, Ninth Revision (ICD-9) codes (456.0 for esophageal varices with bleeding, and 456.1 for esophageal varices without bleeding), and International Classification of Diseases, 10th Revision (ICD-10) codes (I85.01 for esophageal varices with bleeding, and I85.00 for esophageal varices without bleeding) in the first two discharge diagnoses. The propensity score to calculate the inverse probability treatment weighting (IPTW) to adjust between the differences of the compared groups was implemented. Two groups were compared in terms of their hospitalization outcomes, including LOS, hospital charges, hospital mortality, and disposition.

Results

A total of 322,761 patients were admitted with esophageal varices between 2011 and 2018, with 236,802 (73.6%) had bleeding esophageal varices and 85,959 (26.4%) had nonbleeding esophageal varices. The majority of the patients from both groups were white (66%), covered with Medicare (38% in the esophageal varices with bleeding vs. 41% in the nonbleeding group). There was a steady increase of patients admitted with nonbleeding esophageal varices. Most common comorbidities were liver diseases, alcohol abuse, uncomplicated hypertension and depression in both groups. There were no significant changes in OLS over the years in both groups, but there was a significant increase in hospital charges, especially in the patients with bleeding esophageal varices starting in 2015, and no change in mortality throughout the years. Regarding hospital disposition, there was a notable decline in rehab discharge in the bleeding esophageal varices group.

Conclusions

Esophageal varices with and without bleeding have been steadily increasing since the beginning of this century. This may result in a substantial impact on increasing health care costs and utilization due to acute variceal hemorrhage. Odds of death, transfer to urban hospital, and transfer to visiting nursing assistance remained unchanged.

A Rare Case of Severe Jaundice in a Panhypopituitarism Patient

Hyperbilirubinemia and transaminitis are rarely associated with a disorder of endocrine function. It mostly manifests as a cholestatic pattern of liver injury. Herein, a 25-year-old female patient with a past medical history of congenital hypopituitarism due to pituitary ectopia presented with serum direct bilirubin level of 9.9 mg/dL and aspartate transaminase (AST)/alanine transaminase (ALT) of 60/47 U/L. All tests for chronic liver disease imaging and liver biopsy were normal. She was found to have central hypothyroidism and low cortisol level. She was started on intravenous (IV) levothyroxine 75 µg daily and IV hydrocortisone 10-5 mg AM/PM. She was discharged on oral levothyroxine 88 µg daily and hydrocortisone orally 10 mg twice daily. Follow-up labs 1 month later showed completely normal liver function test. In conclusion, hyperbilirubinemia due to congenital hypopituitarism can occur in adults. Delayed recognition of underlying endocrine disorder as a cause of hyperbilirubinemia and hepatocellular inflammation can result in end-stage liver damage due to prolonged cholestasis.

A Rare Case of Anterograde Gastroduodenal Intussusception Caused by Migrated Percutaneous Endoscopic Gastrostomy Feeding Tube

Gastroduodenal intussusception is a critical condition in which stomach protrudes into the duodenum. It is a very rare condition in adults. Most common causes include intra luminal lesions in the stomach including benign or malignant tumors of the stomach. Most common tumors included are gastrointestinal stromal tumors (GISTs), gastric carcinoma, gastric lipoma, gastric leiomyoma, and gastric schwannoma. It is extremely rare to be caused by migration of percutaneous feeding tube. A 50-year-old woman with a past medical history (PMH) of dysphagia status post percutaneous endoscopic gastrostomy (PEG) tube, history of spastic quadriplegia, presented with acute nausea, vomiting and abdominal distention, and was found to have gastroduodenal intussusception in computed tomography (CT) scan. Condition resolved after retracting PEG tube. Endoscopy did not reveal any intra luminal lesions. External fixation using Avanos Saf-T-Pexy T-fasteners was performed to prevent recurrence of this condition. Most common of causes of gastroduodenal intussusception are GIST tumors of stomach. CT abdomen is the most accurate test and upper endoscopy is needed to rule out any intra luminal causes. Treatment of choice is either endoscopic or surgical resection. External fixation is essential to prevent recurrence.

Endoscopic stricturotomy with pulsed argon plasma and balloon dilation for refractory benign colorectal strictures: a case series

Benign strictures of the colon and rectum affect a sizable portion of patients who have an underlying inflammatory disease or who have undergone recent surgery. Etiologies include inflammatory bowel disease (IBD), post-surgical ischemia, anastomotic strictures, non-steroidal anti-inflammatory drugs (NSAIDs), and complicated diverticulitis. Refractory colorectal strictures are very difficult to manage and often require repeated and different treatment options. We report a novel technique using argon plasma coagulation (APC) with endoscopic balloon dilation (EBD) as a safe and effective treatment modality for refractory benign colorectal strictures. Four patients with symptomatic benign colorectal strictures were referred for endoscopic treatment. In all cases (two females and two males; average age 62 years), the endoscopic and radiographic assessment showed significant strictures (diameter, 4-13 mm). The stricture was secondary to Crohn's disease in one patient and anastomotic strictures in the other three patients. Endoscopic stricturotomy through fulguration and tissue destruction using argon plasma at 1.5 liters/minute, effect 2, and 40 watts was performed, followed by EBD. All patients were treated by one advanced endoscopist. The primary outcomes were the efficiency and safety of endoscopic stricturotomy with pulsed argon plasma and balloon dilation. The resolution of stricture was achieved in all patients. No complications were reported. We believe that combined APC with EBD is a safe and effective technique in the treatment of benign colonic stricture.

The Tale of a Bleeding Tree: A Rare Case of Peripancreatic Variceal Hemorrhage Causing Hemosuccus Pancreaticus

Hemosuccus pancreaticus (HP) is a rare cause of upper gastrointestinal bleeding. It was described by Lawal and Farrel in 1931. This disorder has also been referred to as pseudohemobilia or wirsungorrhagia, caused by bleeding into the pancreatic duct. The rarity of this condition can pose a diagnostic challenge. HP is life-threatening and requires immediate attention. The commonly used treatment modality is coil embolization. Surgery is considered in the case of failed embolization or uncontrolled bleeding. Described below, is a case of a 72-year-old female with a history of chronic pancreatitis who presented with anemia secondary to bleeding peripancreatic varices.

Two Patients With Difficulty in Swallowing due to Dysphagia Lusoria

Dysphagia lusoria (DL) is a rare clinical entity caused by compression of the esophagus by an aberrant right subclavian artery. It is coined from the Latin word meaning freak or jest of nature, with an estimated prevalence of approximately 0.5%. Before the term DL was known, the artery abnormality was referred to as luxus nature. Most patients are asymptomatic. In 30-40% of cases, DL results in tracheoesophageal symptoms like dysphagia to solid foods, chest pain, cough, and Horner’s syndrome. Symptoms presenting later in life have been linked to arteriosclerosis and diminishing esophageal compliance resulting in compression. Another reason why people become symptomatic is due to Kommerell’s diverticulum, a disorder that was first described by Kommerell, a German radiologist in 1936. It is also known as lusoria diverticulum, remnant diverticulum or lusoria root. This disorder represents a remnant of the left dorsal arch which forms a vascular ring behind the esophagus, leading to external compression. The key to diagnosis of DL is a barium esophagogram which may show extrinsic compression. Computed tomography or magnetic resonance imaging can be used for definite delineation of the vascular anatomy. Treatment approach is dietary modification or surgical intervention for unresponsive cases. Here, we present cases of dysphagia in two middle-aged women caused by compression effect on the esophagus by an aberrant right subclavian artery who did not respond to dietary modification.

Closure of recurrent colovaginal fistulas using AMPLATZER occluder device

A 79-year-old woman and a 92-year-old woman were referred to the gastroenterology department for management of persistent colovaginal fistula despite surgical and non-surgical management. Both patients had several hospitalisations for recurrent urinary tract infections. After failed surgical management and endoscopy using over-the-scope clipping, both patients underwent endoscopic closure using the Amplatzer cardiac septal occluder device. Both patients underwent successful closure and had no recurrence of symptoms at 6-month follow-up. Although there are several therapies available for persistent colovaginal fistulas, most involve multiple sessions and have high recurrence rate. There have been reports in the literature of cardiac septal occluders being used in the management of upper gastrointestinal tract fistulas, but few cases exist explaining their role in the management of colovaginal fistulas. Our cases demonstrate that cardiac septal occluders may be a viable option for management of fistulas and warrants further studies to reproduce its effectiveness and safety.

A Complicated Parenchymal-Esophageal Fistula in Non-Small Cell Lung Cancer

Respiratory digestive fistula (RDF) is an abnormal communication between the airway and the digestive tract. Only 3-11% of RDF communications are parenchymal-esophageal fistulas. We present a case of a 58-year-old male who presented to the emergency department with dysphagia and cough after swallowing. He was diagnosed with stage III/B non-small cell lung cancer. The patient was previously treated with chemotherapy, radiation, and immunotherapy. Computed tomography (CT) scan of the chest with contrast showed a chronic cavitary right upper lobe lesion in the previously treated malignancy area. New right paratracheal adenopathy, right esophageal wall thickening, and bilateral lung infiltrates were also shown. Upper endoscopy with bronchoscopy and endobronchial ultrasound (EBUS) was done to evaluate mediastinal lymphadenopathy as well as dysphagia. A tract was found extending from the right lung cavity into the esophagus through the mediastinum. Esophagoscopy was subsequently performed, and a fistula was observed on the right wall of the mid-esophagus. The defect was favorable for clipping, which was successfully closed with an 11/6 traumatic over the scope clip, followed by a fully covered esophageal stent. The patient’s respiratory and gastrointestinal symptoms improved after the procedure. Follow-up barium swallow was negative for any esophageal leak. At three-month follow-up, the patient was free of recurrent pulmonary and gastrointestinal symptoms that he presented with. Palliative therapy is the targeted therapy for RDF management. RDF is either managed conservatively or with radiation, chemotherapy, or surgery to obliterate the connection. Surgical correction usually is not an option since patients typically have a poor functional status at the time of diagnosis. Considering the survival and recurrence rate medical intervention is the mainstay of treatment. Parallel dual (esophageal-bronchial) stenting has been proven to provide the best outcomes. Self-expanding metal stents (SEMS), either covered or partially covered, are used extensively to manage malignant RDF.

Ascending Cholangitis Caused by Methicillin-Resistant Staphylococcus aureus Species in a Patient With Cystic Fibrosis

Ascending cholangitis is a bacterial infection of the extra-hepatic biliary system and presents as a life-threatening systemic condition. Increased bacterial loads and biliary obstruction favor bacterial translocation into the vascular and lymphatic systems. Common organisms isolated are Escherichia Coli, Klebsiella, Enterococcus species, and Enterobacter species. Methicillin-resistant Staphylococcus aureus (MRSA) is a rare isolate in ascending cholangitis. We present a case of a 24-year-old patient with cystic fibrosis who presented with epigastric abdominal pain, low-grade fever, jaundice, dark urine, and nausea for two days. Initial workup revealed elevated liver enzymes, hyperbilirubinemia, leukocytosis, and an ultrasound which showed common bile duct dilation to 14 mm with choledocholithiasis. He underwent endoscopic retrograde cholangiopancreatography (ERCP) with stone extraction and bile fluid culture. Cultures grew out MRSA and the patient was treated with appropriate antibiotic therapy. The mainstay of therapy for ascending cholangitis is adequate hydration, antibiotics, and biliary decompression. Early recognition of the offending organism is critical in guiding therapy. Current guidelines focus on the empiric treatment of Gram-negative and anaerobic bacteria. Clinicians should be aware of the possibility of less common pathogens (such as MRSA), especially in a patient who is decompensating despite antibiotic therapy.

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.

Exploring the Excluded Stomach: A Case Series of Novel Endoscopic Techniques to Diagnose Gastric Cancer in the Excluded Stomach After Roux-en-Y Gastric Bypass Surgery

Gastric cancer is the fifth most common malignancy worldwide and the fourth leading cause of cancer-related deaths. The diagnosis is usually made by direct visualization with supporting histopathology. However, patients with gastric bypass surgery pose a challenge in diagnosis due to the difficulty in the evaluation of the excluded stomach. We present two cases of gastric cancer in the excluded stomach after Roux-en-Y gastric bypass (RYGB) surgery was diagnosed using two different endoscopic approaches.

Lumen-apposing metal stents for drainage of pancreatic fluid collections: When and for whom?

BACKGROUND AND AIM

Although lumen-apposing metal stents (LAMS) are increasingly being used for drainage of pancreatic fluid collections (PFC), their advantage over plastic stents is unclear.

METHODS

In this retrospective case-control study, 20 patients who underwent PFC drainage using LAMS were matched with 40 patients treated with plastic stents according to PFC type (walled-off necrosis [WON] vs pseudocyst) and procedural technique (conventional vs multi-gate). Main outcome measures were treatment success, reintervention, clinical and stent-related adverse events, procedural duration, length of hospital stay (LOS) and hospital costs.

RESULTS

At median follow up of 570 days, except for median procedural duration (8.5 vs 25 min, P < 0.001), there was no significant difference in treatment success (95.0 vs 92.5%, P = 0.99), reintervention (25.0 vs 30.0 %, P = 0.77), clinical (10.0 vs 12.5 %, P = 0.99) and stent-related adverse events (10.0 vs 2.5 %, P = 0.26) or median LOS (2 [IQR 1-5] vs 2 [IQR 1-7] days, P = 0.58) between patients treated with LAMS versus plastic stents. Although there was no difference for WON ($16 708 for LAMS vs $17 221 for plastic stents, P = 0.90), mean hospital costs were significantly lower for pseudocysts using plastic stents ($18 996 vs $58 649, P = 0.03).

CONCLUSIONS

Although there is no difference in clinical outcomes, treating pseudocysts using plastic stents is less expensive. It is also possible that the short procedural duration is a surrogate marker for procedural complexity and this may drive the use of LAMS in sicker patients.

Superior mesenteric artery-duodenal fistula secondary to a gunshot wound

Arterioenteric fistulas are a rare cause of massive gastrointestinal hemorrhage. We present a patient who developed a fistula between a middle colic artery pseudoaneurysm, a proximal branch of the superior mesenteric artery (SMA), and the third part of the duodenum 2 weeks after a self-inflicted gunshot wound to the abdomen. The patient's presentation, evaluation, treatment, and prognosis are discussed. All prior published cases of SMA-duodenal fistulas are reviewed.

Left ventricular assist devices and gastrointestinal bleeding: a narrative review of case reports and case series

BACKGROUND

The use of left ventricular assist devices (LVADs) has become a state-of-the-art therapy for advanced cardiac heart failure; however, multiple reports in the literature describe an increased risk for gastrointestinal (GI) bleeding in these patients. We characterized this association by reviewing recent studies on this topic.

HYPOTHESIS

GI bleeding occurs frequently in patients with LVADs, especially with devices with nonpulsatile flow patterns.

METHODS

We performed a comprehensive literature review to identify articles that reported GI bleeding in patients with LVADs. Databases used included PubMed, EMBASE, Scopus, Web of Knowledge, and Ovid. Baseline and outcome data were then ed from these reports.

RESULTS

We identified 10 case reports and 22 case series with 1543 patients. The mean age was 54.2 years. Most patients had nonpulsatile LVADs (1316, 85.3%). Three hundred and seventeen patients (20.5%) developed GI bleeding; this occurred more frequently in patients with nonpulsatile LVADs. Multiple procedures were performed without complications but often did not identify a definite bleeding site. Suspect lesions occurred throughout the GI tract but were more frequent in the upper GI tract. Many patients had arteriovenous malformations. All patients received medical therapy. None of the patients had their LVAD replaced. The use of anticoagulation did not appear to predispose these patients to more GI bleeding episodes.

CONCLUSIONS

Patients with LVADs have frequent GI bleeds, especially from arteriovenous malformations, which can occur throughout the GI tract. Most diagnostic and therapeutic interventions can be used safely in these patients. The pathogenesis of the GI bleeding in these patients may involve the use of anticoagulant medications, the formation of arteriovenous malformations, loss of von Willebrand factor activity, and mucosal ischemia.

Oropharyngeal flora in patients admitted to the medical intensive care unit: clinical factors and acid suppressive therapy

Acid suppression therapy in critically ill patients significantly reduces the incidence of stress ulceration and gastrointestinal (GI) bleeding; however, recent studies suggest that proton pump inhibitors (PPIs) increase the risk of pneumonia. We wanted to test the hypothesis that acid suppressive therapy promotes alteration in the bacterial flora in the GI tract and leads to colonization of the upper airway tract with pathogenic species, potentially forming the biological basis for the observed increased incidence of pneumonia in these patients. This was a prospective observational study on patients (adults 18 years or older) admitted to the medical intensive care unit (MICU) at a tertiary care centre. Exclusion criteria included all patients with a diagnosis of pneumonia at admission, with infection in the upper airway, or with a history of significant dysphagia. Oropharyngeal cultures were obtained on day 1 and days 3 or 4 of admission. We collected data on demographics, clinical information, and severity of the underlying disease using APACHE II scores. There were 110 patients enrolled in the study. The mean age was 49±16 years, 50 were women, and the mean APACHE II score was 9.8 ± 6.5. Twenty per cent of the patients had used a PPI in the month preceding admission. The first oropharyngeal specimen was available in 110 cases; a second specimen at 72-96 h was available in 68 cases. Seventy-five per cent of the patients admitted to the MICU had abnormal flora. In multivariate logistic regression, diabetes mellitus and PPI use were associated with abnormal oral flora on admission. Chronic renal failure and a higher body mass index reduced the frequency of abnormal oral flora on admission. Most critically ill patients admitted to our MICU have abnormal oral flora. Patients with diabetes and a history of recent PPI use are more likely to have abnormal oral flora on admission.

Patterns of Use of Prophylaxis for Stress-Related Mucosal Disease in Patients Admitted to the Intensive Care Unit

Background:

Morbidity associated with stress ulcer–related bleeding, the cost of medications, and the possible complications associated with stress ulcer prophylaxis are important considerations when prescribing prophylaxis. We prospectively studied the prescription patterns for stress ulcer prophylaxis in patients admitted to our ICU.

Methods:

We prospectively recorded the indications for stress ulcer prophylaxis and prescription patterns for use based on the American Society of Healthcare Pharmacists criteria and other indications for 99 new intensive care unit (ICU) admissions to a tertiary referral center.

Results:

In all 51 patients had no indication for stress ulcer prophylaxis, 32 had 1 indication, 14 had 2 indications, and 2 patients had 3 indications for receiving stress ulcer prophylaxis in the ICU. Eighty-two percent of patients without any indications received stress ulcer prophylaxis; 81% of patients with 1 indication, 79% of patients with 2 indication, and 50% of patients with 3 indications received stress ulcer prophylaxis. Overall, 53% of patients either received stress ulcer prophylaxis when none was indicated or did not receive stress ulcer prophylaxis when it was indicated. We also review the recent literature on stress-related mucosal disease and the use of prophylaxis for stress-related mucosal disease.

Conclusions:

Stress ulcer prophylaxis administration in this ICU is inconsistent and includes both underutilization and overutilization. Educating physicians and implementing hospital protocols could improve use patterns.
