Can the affected intestinal segment visualized on abdominal ultrasound predict gastrointestinal tract bleeding in immunoglobulin A vasculitis?

To evaluate immunoglobulin A vasculitis (IgAV) patients with gastrointestinal (GI) tract involvement and to reveal the relationship between the location and extent of the affected intestinal segment detected on the initial abdominal ultrasound (US) and GI tract bleeding. This medical record review study was conducted on 117 IgAV patients with GI tract involvement between January 2016- June 2023. Patients were divided into two groups as those with (n=28) and without (n=89) GI tract bleeding. Predictors of GI tract bleeding were investigated by comparing demographic, clinical characteristics and laboratory findings. Gender, age at diagnosis, symptoms at admission, rash distribution, GI tract complaints, and the elapsed time until the development of GI tract symptoms were similar in both groups. There was no difference between small intestinal, large intestinal or small+large intestinal involvement (p=0.89). The ileum was the most commonly affected intestinal segment in patients with and without GI tract bleeding (p=0.37). Jejunal wall thickening (p=0.04) and the number of affected intestinal segments (p=0.008) were higher in patients with GI tract bleeding. In IgAV patients, jejunum involvement and affected multiple intestinal segments shown by abdominal US are associated with GI tract bleeding.

Survey of Emergency Department Clinicians on the Utility of the Guaiac Fecal Occult Blood Test.

Emergency department (ED) clinicians utilize the guaiac fecal occult blood test (gFOBT) in their assessment of suspected gastrointestinal bleeding or unexplained anemia despite supporting evidence. ED clinicians' ability to predict the gFOBT results and how the gFOBT results could affect ED patient disposition has not been previously studied. Methods: From October 16, 2019, through September 15, 2020, we conducted a single-site survey of ED clinicians before and after performing gFOBTs during routine clinical care. Survey data were collected and retrospectively evaluated with unadjusted and multivariable regression analyses. We examined a total of 133 combined pre-gFOBT and post-gFOBT surveys. ED clinicians accurately predicted gFOBT results with an area under the receiver operating characteristic curve of 0.75 (95%CI, 0.66-0.85). Of clinician-predicted certain or very probable positive gFOBT results, only 79% were actually positive. In multivariable analyses, decreased hematocrit level (odds ratio (OR), 0.31/10% increase; 95%CI, 0.14-0.61), decreased red blood cell count (OR, 0.41/1x1012/L increase; 95%CI, 0.21-0.75), and absence of firm stool consistency (OR, 0.09; 95%CI, 0.01-0.42) were associated with positive gFOBT results (allP<.006). The most common reason for performing gFOBTs was black stool or suspected melena, followed by decreased hemoglobin level, red blood in stool, and suspected upper gastrointestinal tract bleeding. Before performing gFOBT, 50.8% of clinicians responded that the test results would change patient disposition, which decreased to 30.5% after the gFOBT result. We found that ED clinicians cannot predict the gFOBT results with high accuracy. A suspected GI bleed is the main reason for performing the test in the ED.

Unusual gastrointestinal bleeding - Small intestinal venous ectasias.

A 34-year-old man presented to our emergency department with a 6-day history of bloody stools. He had no complaints of alteration in bowel habits in the stool. He did not consume alcohol and was a non-smoker. The patient had no any previous notable medical history or family history of similar complaints. Physical examination was unremarkable. In the local hospital, laboratory studies showed a hemoglobin level of 6.0g per deciliter (normal range, 11.5 to 15.5). After blood transfusion, an upper gastrointestinal endoscopy and complete colonoscopy did not reveal any bleeding lesion. In our hospital, the patient underwent abdominal contrast-enhanced CT, small intestinal venous ectasias were detected. The selective angiography was performed, but no aneurysm or arteriovenous fistula was found. The gastrointestinal tract bleeding still occurred for an unknown reason. Subsequently, single-balloon enteroscopy was carried out. By oral approach enteroscopy, obvious jejunum venous ectasias were detected.

Abernethy Malformation and Gastrointestinal Bleeding: A Case Report and Literature Review.

Background: Congenital extrahepatic portosystemic shunt (CEPS), also termed Abernethy malformation (AF) is a rare anomaly of the splanchnic venous system. Several approaches, including shunt closures through surgical or radiological interventions and liver transplantations, have been proposed, but clear comparisons among different treatment strategies are still unavailable. Purpose: We report a case in which an unusual portosystemic shunt was present between the dilated inferior mesenteric vein (IMV) to the right ovarian vein. A mini literature review of AF patients presented with gastrointestinal (GI) tract bleeding. Research design: Case report and literature review. Data Collection: An electronic search of PubMed was performed from inception to December 2023. Results: 34 AF patients presented with GI tract bleeding were identified published in the literature. The proportion of type II AF patients presenting with GI bleeding is greater (79%). Conclusions: We regard that both surgical ligation and endovascular closure of the shunt are effective and safe treatments for these patients, but coils embolization alone may not be sufficient to completely close the shunt when the shunt flow is high.

Polypoid heterotopic gastric mucosa: in terminal ileum causing extensive lower gastrointestinal bleeding without Meckel’s diverticulum: a case report

BackgroundHeterotopic gastric mucosa (HGM) can be located in various parts of the gastrointestinal tract. As a rare anomaly in the small intestine, it can become complicated by intussusception, obstruction, gastrointestinal bleeding, and even peritonitis, leading to death.Case presentationThis case report focuses on a 12-year-old Middle Eastern boy who presented with hematochezia and abdominal pain for a couple of days. A tagged Red blood cell (RBC) scan and Technetium scan revealed gastrointestinal bleeding at the lower abdomen, highly suggestive of the diagnosis of Meckel’s diverticulum. Subsequently, exploratory laparotomy revealed contiguous and scattered mucosal lesions with multiple polyps of various sizes in the terminal ileum. Meckel’s diverticulum was absent, and the patient was treated with resection and primary anastomosis. The resected tissue revealed extensive ectopic gastric mucosa and polypoid tissues. The patient recovered uneventfully and was discharged four days after the surgery. The symptoms did not recur within six months after his surgery.ConclusionOur case demonstrated that despite the rarity of multiple polypoid gastric heterotopias in the terminal ileum, it should be considered as one of the differential diagnoses of gastrointestinal tract bleeding.

Endovascular embolization of a biliary–digestive loop bleeding

Delayed massive hemorrhage after biliary surgery is a severe complication and carries a high mortality rate. Upper gastrointestinal (GI) tract bleeding is usually managed endoscopically. However, the presence of altered anatomy following hepato-biliary surgery does preclude endoscopic exploration of the anastomoted loop. In our case of hemorrhage from biliodigestive anastomosis, CT angiography provides accurate information about the presence of active bleeding and its source. We present a case of bleeding from a biliary–digestive loop. The patient exhibited several bleeding risk factors, notably cirrhosis and dual antiplatelet therapy. Furthermore, the site of bleeding, the biliarydigestive loop, had experienced a fistula with a hepatic abscess 2 years earlier, following percutaneous thermoablation. Endovascular embolization with microparticles 300–500 µm and one microcoil 2mx4cm proved to be a safe and effective treatment in this high-risk patient with persistent bleeding. Developments in interventional radiology equipment and techniques, such as low-profile catheter systems and advanced embolic agents, validate embolization as a suitable therapeutic option.

Ultra-minimally invasive endoscopic techniques and colorectal diseases: Current status and its future

Colorectal diseases are increasing due to altered lifestyle, genetic, and environmental factors. Colonoscopy plays an important role in diagnosis. Advances in colonoscope (ultrathin scope, magnetic scope, capsule) and technological gadgets (Balloon assisted scope, third eye retroscope, NaviAid G-EYE, dye-based chromoendoscopy, virtual chromoendoscopy, narrow band imaging, i-SCAN, etc. ) have made colonoscopy more comfortable and efficient. Now in-vivo microscopy can be performed using confocal laser endomicroscopy, optical coherence tomography, spectroscopy, etc. Besides developments in diagnostic colonoscopy, therapeutic colonoscopy has improved to manage lower gastrointestinal tract bleeding, obstruction, perforations, resection polyps, and early colorectal cancers. The introduction of combined endo-laparoscopic surgery and robotic endoscopic surgery has made these interventions feasible. The role of artificial intelligence in the diagnosis and management of colorectal diseases is also increasing day by day. Hence, this article is to review cutting-edge developments in endoscopic principles for the management of colorectal diseases.

A case report of non hodgkin lymphoma presenting with upper gastrointestinal tract bleeding

Abstract: Initial evaluation of patients with acute gastrointestinal (GI) tract bleeding includes assessment of hemodynamic stability and resuscitation if necessary Case Report: A 48-year-old male patient was admitted to the emergency department with complaints of dizziness, intense weakness, vomiting in the form of coffee grounds and black diarrhea Conclusion: Aggressive non-hodgkin lymphoma may be among the etiologies of upper gastrointestinal bleeding. In cases where endoscopic and surgical methods are inadequate, chemotherapy may be a life-saving option considering the possible risks.

Meta-analysis: Over-the-scope clips in patients at high risk of re-bleeding following upper gastrointestinal tract bleeding.

Acute non-variceal upper gastrointestinal bleeding (UGIB) is challenging in patients at high risk of re-bleeding in whom standard endoscopic treatment (ST) has limited effectiveness. Over-the-scope clips (OTSC) have shown promise in these patients although their precise role remains uncertain. To confirm the role of OTSC in patients with UGIB at high risk of re-bleeding. We systematically searched CENTRAL, MEDLINE and Embase from January 1st, 1970 to April 24, 2024 for randomised controlled trials (RCTs) comparing OTSC and ST in acute non-variceal UGIB with high re-bleeding risk. The GRADE framework assessed evidence certainty, while trial sequential analysis (TSA) controlled random errors and evaluated conclusion validity. We analysed four RCTs (319 patients); pooled risk ratio (RR) for clinical success at initial endoscopy favoured OTSC (RR = 1.30, 95% CI = 1.08-1.56, p = 0.006, I2 = 58%, moderate certainty of evidence). TSA showed the desired sample size was 410 and the cumulative Z curve crossing the trial sequential monitoring boundary. The pooled RR for re-bleeding within 30 days favoured OTSC (RR = 0.53, 95% CI = 0.30-0.94, p = 0.03, I2 = 0%, moderate certainty of evidence). There was no significant difference in 30-day mortality, or length of hospital or ICU stay. Moderate certainty evidence supports OTSC as a superior initial treatment for acute non-variceal UGIB with high re-bleeding risk. Further large-scale studies are needed to confirm OTSCs' role by exploring other prognostic outcomes and assessing cost-effectiveness and potential complications.

Helicobacter pylori Infection in Children With Cerebral Palsy: A Cross-Sectional Study

BackgroundChildren with cerebral palsy (CP) frequently have associated disorders and complications, including gastrointestinal problems. Helicobacter pylori is a common infection worldwide, frequently associated with gastrointestinal manifestations. MethodsTo estimate the prevalence of H. pylori infection in children with CP, a cross-sectional study over an eight-month period was performed in the pediatric neurology outpatient clinic of Tanta University Hospital. The study included 100 patients with CP aged two to 17 years. All patients were tested for H. pylori antigen in stool by enzyme-linked immunosorbent assay. ResultsThe mean age of studied children with CP was 7.03 ± 4.1 years; there were 57 males and 43 females. Spastic quadriplegic CP was the most common type of CP (34%). Forty-five children with CP were positive for H. pylori antigen in stool. Intellectual disability (ID), low sociodemographic scoring system, semisolid diet, and Eating and Drinking Ability Classification System (EDACS) levels 4 and 5 were significant predictors of H. pylori infection (odds ratio of 1.86, 2.63, 12, and 1.77, respectively, P < 0.05). Vomiting, abdominal pain, and gastrointestinal tract bleeding were significantly more frequent in H. pylori-infected children with CP than noninfected children with CP (P value < 0.05) ConclusionH. pylori is a relatively common infection among children with CP. The main risk factors for H. pylori infection were low socioeconomic level, ID, semisolid diet, and EDACS levels 4 and 5.

NSAID-Induced Lower Gastrointestinal Bleeding: A Case Report

Abstract Nonsteroidal anti-inflammatory drugs (NSAIDs) are well known to cause ulcers and bleeding in the upper gastrointestinal tract. Furthermore, several studies to date have demonstrated that NSAIDs may also cause ulcers in the lower gastrointestinal tract, or the bowel, resulting in small bowel bleeding. The diagnosis and management of bleeding in the small bowel region pose a significant challenge. Here, we present the case of a 30-year-old female who presented to the hospital with lower gastrointestinal bleeding after taking an NSAID for a prolonged period. The results of all investigations, including computed tomography angiography, esophagogastroduodenoscopy, colonoscopy, and digital subtraction angiography, were negative. The patient was transferred to the operating room for an on-table colonoscopy and surgical intervention because of continuous bleeding and hemodynamic instability. During the operation, a suspected bleeding site was located in the terminal ileum, leading to the resection of the small bowel, which revealed ulcerative lesions. NSAIDs are believed to have caused the ulcer in this patient, as evidenced by all the available information, including the pathological results.

A comprehensive review on phytochemicals as potential therapeutic agents for stress-induced gastric ulcer

AbstractGastric ulcers are the most common chronic gastrointestinal tract disorders, marked by an inflamed break of the mucus membrane covering the alimentary tract. According to recent research, stress-induced ulcers are widespread in our society. A stress ulcer is a mucosal defect that may become complicated due to upper gastrointestinal tract bleeding. The underlying cause of this condition is pH. Physiological stress leads to severe sickness by triggering the excessive secretion of peptic juices or gastric acid. There is a never-ending quest for safe and affordable medication for this disorder. Nature offers many medicinal plants that can be used to treat a wide range of human ailments. Due to their relatively harmless and comparatively free of harmful effects, health-promoting features, pharmacological practices, and affordability to common people to regulate various diseases, medicinal plants, and herbal preparations are gaining a lot of interest in scientific communities these days. Many studies have recently been performed to classify extracts and their constituents that may have a therapeutic effect on peptic ulcers. Therefore, this review aims to address the molecular mechanisms and pharmacological effects of various phytochemicals related to stress-induced gastric ulcers. Combining phytochemical constituents with modern drugs and treatment methods can lead to the development of therapeutic drugs for gastric ulcers. Gastric ulcers and other related diseases may be treated permanently with this approach.

Histopathology and molecular pathology confirmed a diagnosis of atypical Caroli’s syndrome: a case report

Caroli’s syndrome is a congenital disease characterized by dilation of intrahepatic bile ducts and congenital hepatic fibrosis. It is a rare condition in clinical work. Typically, the diagnosis of this disease is confirmed through medical imaging. Here, we report a case of atypical Caroli’s syndrome in a patient who presented with recurrent upper gastrointestinal tract bleeding. The patient underwent imaging examinations, liver biopsy and whole exome sequencing. The results of the imaging examination were non-specific. However, with the aid of pathological examination, the patient was diagnosed with Caroli’s syndrome. In conclusion, for cases where the imaging presentation of Caroli’s syndrome is inconclusive, an accurate diagnosis should rely on pathology. By discussing this specific case, our aim is to enhance readers' understanding of this disease, provide valuable information that can aid in the early detection and appropriate management of Caroli’s syndrome, ultimately improving patient outcomes.

MONITORING OF MEDICINE THERAPY IN DM (Diabetes Mellitus) PATIENTS, MELENA, ANEMIA, HIPOALBUMIN AND SEPSIS IN HOSPITAL “ X ”

Diabetes Mellitus (DM) is a group of chronic metabolic diseases with hyperglycemia characteristics, this disease can attack several organs of the body causing various complaints. Diabetes Mellitus (DM) is a disease characterized by blood sugar levels. Physical activity is any body movement produced by skeletal muscles that requires energy. Lack of physical activity is an independent risk factor for chronic disease. This study aims to determine the effect of physical activity on blood sugar levels in patients with diabetes mellitus. Sepsis is the invasion of pathogenic microorganisms or their toxins into the blood or other tissues, resulting in an exaggerated systemic response to infection, which causes a collection of clinical symptoms and ends in a life-threatening state of organ dysfunction. Anemia is indeed not a direct complication caused by Type 2 DM, but in patients with diabetes, diabetes can damage blood vessels in the body and can cause kidney problems in the long term if not controlled. Impaired kidney function can cause anemia. Melena is a condition when the stool becomes dark or black in color, which is caused by bleeding in the upper gastrointestinal tract. Hypoalbuminemia in critical illness is an important marker of mortality. The pathophysiology of hypoalbuminemia in critical illness including decrease of production, inflammation marker, vascular leakage, and malnutrition. Administration of intravenous human albumin is needed to be considered for treatment of hypoalbuminemia in critical illness.This report was conducted to find out drug related problems (DRP's) in the treatment management of DM (Diabetes Melius) Patients, Melena Anemia, Hipoalbumin and Sepsis at “ X “ Hospital. The patient on behalf of Mrs.R.M was treated in the inpatient room. Drug Therapy Monitoring to ensure rational use of drugs, so that unwanted events do not occur.

Acute respiratory failure prognosis in prolonged ICU stays

Objective: This study aimed to assess the outcome of patients with acute respiratory failure and need of mechanical ventilation who stayed for more than 21 days in the ICU. Methods: All acute respiratory failure patients in King Saud Medical City, Riyadh Saudi Arabia and adults ICU who required a lengthy intensive care unit stay of more than 21 days between January 2022 and August 2023 were identified in this retrospective study. Information was extracted from the hospital database by trained physicians. Results: Total 121 patients (mean age 61.2±15.8 years) were included. Of which, 24.1% patients were more than 70 years. Sepsis was the most common cause of prolonged ICU stay both in survivors and non-survivors with 77.8% and 76.1%, respectively. Compared to patients who survived, non-survivors had higher acute physiology and chronic health evaluation (APACHE 4) scores were considerably older. Moreover, non-survivors were more likely than survivors to have renal failure, arrhythmia, hepatic failure, or significant gastrointestinal tract bleeding as reasons for a lengthy ICU stay. Patients who were admitted to ICU because they needed further surgery were more likely to survive. Conclusion: When acute respiratory fever (ARF) patients needed a lengthy stay in the ICU, their prognosis was not good. A high risk of in-hospital death was linked to older ages, more than 28 days ICU stay, more than 25 APACHE 4 score, unstable hemodynamic condition, hepatic failure, renal failure, major gastrointestinal tract bleeding, and needing FiO2 &amp;ge;40%.

Hypovolemic Shock Due to Lower Gastrointestinal Tract Bleeding Secondary to Primary Rectal Syphilitic Ulcer. Case Report and Literature Review

Syphilis is a sexually transmitted disease caused by the spirochete Treponema pallidum, it has a well-defined course with several stages throughout its natural history ranging from primary to tertiary. Rectal syphilis is a rare syphilis presentation and can occur in both primary and secondary syphilis, either in a syphilitic ulcer or proctitis. It's generally doesn't have symptoms, however it can cause rectal bleeding that in most cases tends to be self-limiting. The diagnosis is established when it's possible with direct observation studies; However, in cases of concomitant contamination by spirochetes of the usual rectal flora, the sensibility and specificity of direct observation tests decreases, so the diagnosis requires an adequate clinical, serological and, if necessary, histopathological correlation. The treatment and follow-up is the same as in other syphilis types and depends on the time of evolution and specific conditions of the patient in question. We present the case of a male patient with primary rectal syphilis that during his course triggered a state of hypovolemic shock secondary to massive rectal bleeding.

Role of Proton Pump Inhibitors in the Management of Peptic Ulcer

Proton pump inhibitors (PPIs) have been used to treat a variety of conditions affecting the upper gastrointestinal tract including gastroesophageal reflux disease (GERD), esophagitis, Zollinger-Ellison syndrome (ZES) and dyspepsia. PPIs are also useful in the treatment of Helicobacter pylori infection as well as the prevention of upper gastrointestinal tract ulcers and bleeding in patients who are taking non-steroidal anti-inflammatory drugs (NSAIDs). It is critical to get the best clinical response possible for people with an upper gastrointestinal peptic disorder. This is dependent on the PPI used. Although all members of this class suppress active parietal cell acid secretion in the same way, there are minor variations in pharmacokinetic characteristics, metabolism and FDA-approved therapeutic indications among PPIs. Regardless of this, each is successful in treating GERD and peptic ulcers. Despite their overall effectiveness, PPIs have certain drawbacks, including short plasma half-lives and the need for meal-associated dosing, which can cause breakthrough symptoms in some people, particularly at night. This article discusses the current indications for PPIs in the treatment of peptic ulcers, as well as their pharmacokinetics and pharmacodynamics.

Smíšený adenoneuroendokrinní karcinom žaludku – kazuistika

Neuroendocrine tumours represent a heterogeneous group of neoplasia arising from different anatomical locations, with approximately 50% of gastrointestinal origin. Main parameters in the evaluation of each case include tumour morphology, mitotic cell count, and Ki-67 index. Mixed adeno-neuroendocrine carcinomas (MANECs) are rare aggressive neoplasms consisting of both adenocarcinomatous and neuroendocrine cells, each component constituting at least 30% of the lesion. Our case represents 77-year-old polymorbid patient who, due to signs of acute bleeding in the upper gastrointestinal tract with anaemic syndrome, underwent a gastroscopic examination for melena with the finding of an ulcer lesion on the front wall of the stomach at the junction of the body and the antrum. The control gastroscopic examinations with biopsies, at first only signs of chronic gastritis with Helicobacter pylori positivity were histologically proven, then fragments of high-grade tubular to tubulovillous adenoma and structures of moderately differentiated tubular adenocarcinoma were found. Histological analysis of the gastric resection showed mixed adeno-neuroendocrine carcinoma with lymphangioinvasion.

Gastrointestinal tract bleeding in children with chronic cholestasis: Prevalence and risk factors in a tertiary referral hospital in Indonesia

Background Cholestasis can lead to several complications, including portal hypertension and risk of gastrointestinal bleeding. However, there is a paucity of studies on the risk factors and prevalence of gastrointestinal tract bleeding in children with chronic cholestasis, particularly in Indonesia.&#x0D; Objective To determine the prevalence and risk factors for gastrointestinal bleeding in children with chronic cholestasis in Cipto Mangunkusumo Hospital, Jakarta, Indonesia.&#x0D; Methods This was a retrospective cohort study in a national referral hospital in Indonesia. Medical records of children with chronic cholestasis who visited the gastroenterohepatology outpatient clinic were collected for five years. Data on clinical symptoms, etiologies, and complications were obtained.&#x0D; Results A total of 97 participants were recruited on this study. The median age of the group was 0.31 years old. The most common causes of chornic cholestasis were biliary atresia, toxoplasma, other infections, rubella, cytomegalovirus, and herpes simplex virus (TORCH) infection, and urinary tract infection. Gastrointestinal bleeding occurred in 27.8% of patients, with hematemesis-melena being the most prevalent symptom. We found that liver cirrhosis, splenomegaly, thrombocytopenia, portal hypertension, and esophageal varices were all highly related with gastrointestinal bleeding. Splenomegaly, thrombocytopenia, and esophageal varices were associated with an increased risk of gastrointestinal bleeding in children with chronic cholestasis (P=0.018, P=0.008, and P=0.039, respectively).&#x0D; Conclusions The prevalence of gastrointestinal tract bleeding in children with chronic cholestasis is 27.8%, with splenomegaly, thrombocytopenia, and esophageal varices as significant risk factors.
