Background: Fecaloma is a mass of hardened feces impacted in the rectum and sigmoid. When the colonic mucosal wall and vasculature are compressed, stercoral colitis, a rare type of inflammatory colitis, may occur. Despite being connected to psychiatric patients and antipsychotic medications in the literature, fecaloma remains a significant, yet often overlooked, cause of morbidity and mortality in this population.

Introduction: Crohn's disease (CD) is a chronic inflammatory condition of the digestive tract, characterized by a noncontinuous pattern of transmural inflammation, leading to a significant decline in quality of life and productivity. For biologic-naïve patients, anti-tumor necrosis factor (TNF)-α and anti-interleukin (IL)-12/23 therapies are commonly recommended. This study compares anti-IL-12/23 and anti-TNF-α for clinical remission, corticosteroid-free remission, endoscopic remission, and endoscopic response in biologic-naïve patients.

Gastroduodenal artery (GDA) pseudoaneurysm is a rare complication of gastric and pancreatic surgery. The presentation is often severe gastrointestinal (GI) bleeding with up to a 90% mortality rate. Proper identification of past gastrectomy based on history or endoscopic appearance is essential for timely embolization or surgery, given that endoscopic management often fails.

Acute acalculous cholecystitis refers to inflammation of the gallbladder without the presence of gallstones or obstruction of the cystic duct. Heart failure is recognized for causing congestive hepatopathy and can lead to gallbladder swelling, often challenging to distinguish from acalculous cholecystitis. Here, we present a case of a patient whose symptoms initially resembled acalculous cholecystitis but were instead caused by acute severe heart failure and cardiogenic shock.

While , , and species traditionally account for most cases of spontaneous bacterial peritonitis (SBP), atypical pathogens can be found. , typically known for causing gastroenteritis, rarely manifests as SBP, while , a zoonotic pathogen, presents a unique challenge in the context of peritoneal infection. In this report, we present two cases of SBP caused by these atypical organisms.

Metronidazole-induced encephalopathy (MIE) is a rare but reversible condition that can present with nonspecific neurological symptoms, making early recognition and diagnosis challenging. Magnetic resonance imaging (MRI) is crucial in identifying typical brain lesions associated with MIE. Prompt discontinuation of metronidazole typically results in symptom resolution and improvement in MRI findings.

Key Clinical Message: It is important to consider the diagnosis of Sump syndrome in patients with a history of open cholecystectomy, particularly in those who migrate from developing countries where alternative biliary interventions may be limited. The presentation may range from acute severe, mimicking acute ascending cholangitis, to chronic recurrent abdominal pain without evidence of inflammation. Management is a case-by-case decision, with principal management aims to decompress the biliary tract and address any underlying sepsis.

Article Synopsis
  • - This study investigates the risk of liver cancer in cirrhotic patients with indeterminate liver nodules, aiming to identify potential predictors for developing hepatocellular carcinoma (HCC).
  • - Over a seven-year follow-up of 116 patients, 16% developed HCC, with significant associations found between HCC incidence and factors like smoking, nodule size over 2 cm, and specific LI-RADS scores.
  • - The results highlight a concerning trend, with up to 30% of patients at risk for HCC after seven years, emphasizing the need for more intensive monitoring and clearer management strategies for these patients.

Article Synopsis
  • Terlipressin, a drug used for conditions like portal hypertension, can cause rare but serious skin necrosis in patients with cirrhosis.
  • Clinicians need to monitor cirrhotic patients closely for this complication and recognize it early to improve outcomes.
  • More research is required to identify risk factors for this adverse effect and to create preventive measures, prompting healthcare providers to balance its benefits against potential risks.

Article Synopsis
  • - Infectious mononucleosis (IM) is a viral illness mainly caused by the Epstein-Barr virus (EBV), commonly affecting teens and young adults, with symptoms like fever, swollen lymph nodes, and sore throat.
  • - A case study describes a 32-year-old woman who developed a rash after taking ibuprofen, which led to the discovery of her undiagnosed IM, confirmed by lab tests for EBV.
  • - This case is significant as it is the first to link NSAIDs with the presentation of IM symptoms, highlighting the importance of being aware of such associations for proper diagnosis and treatment, especially in patients with unexplained skin reactions to medications.

Doxycycline is one of the medications that cause drug-induced esophagitis. This condition occurs due to prolonged contact of the medications with the esophageal mucosa, leading to erosion, ulcers, and, in some cases, stricture of the esophagus. Chest pain, dysphagia, and odynophagia are the most common symptoms.

Sustained low-efficiency dialysis (SLED) is usually performed over 6-12 h among hemodynamically unstable patients. Conduction of 4-h SLED may spare time and manpower during hospitalization. Therefore, we conducted a retrospective observational study to explore the appropriateness and clinical outcomes of 4-h SLED among critically ill patients admitted to our center from 1/06/2016 to 1/06/2020.

TB itself is considered an independent risk factor for VTE; however, developing pulmonary embolism after medical thoracoscopy is extremely rare. Herein, we describe a 30-year-old previously healthy male with pleural tuberculosis developed a massive pulmonary embolism with subsequent cardiac arrest after a diagnostic medical thoracoscopy. Computed tomography pulmonary angiogram (CTPA) showed major right pulmonary embolism (PE).

Introduction: Although ascites is a common complication of congestive heart failure, the association between heart failure and hemorrhagic ascites is quite rare.

Patient Concerns: A 64-year-old woman with recurrent large bloody ascites secondary to heart failure.

Diagnosis: Ascitic fluid assessment revealed red blood cells of 75,125/mm3 and white blood cells of 225/mm3.

Tumor lysis syndrome (TLS) is a hematological emergency. This syndrome is characterized by metabolic derangements such as hyperkalemia and hypocalcemia, which result from rapid lysis of cells, especially rapidly growing tumors, after the initiation of chemotherapy. It is rarely seen in chronic myeloid leukemia (CML) and has not been previously reported to be triggered by coronavirus disease 2019 (COVID-19) infection.

Background: Cost, adverse events, and long treatment duration can be significant obstacles in treating hepatitis C virus (HCV)-infected individuals. Shortening the treatment regimen can minimize these barriers, thereby enhancing adherence and increasing medication availability to more patients.

Methods: This is a single-centre, single-arm, open-label, phase 3 clinical trial on treatment naïve, non-cirrhotic, HCV genotype 4 patients.

Background And Aims: As the pig model has similar gastrointestinal anatomy and physiology to humans, we used pigs to create a gastric mucosal devitalization (GMD) model in preparation for clinical translation of this technique as an endoscopic bariatric therapy (EBT). The aims of this study were to determine the ablation parameters and technique for a successful, safe, and feasible large surface area GMD that produces weight loss.

Methods: We performed GMD using argon plasma coagulation (APC) in 3 phases.

Background And Aim: Despite widespread adoption and encouraging results seen over the last 5 years, no consensus exists regarding the endoscopic sleeve gastroplasty (ESG) technique, training, or preprocedure and postprocedure management of the patient. The aim of our survey was to assess practice trends and preferences of bariatric endoscopists with respect to ESG.

Methods: Using a digital platform, we conducted a worldwide survey by emailing a link with an electronic questionnaire to 1200 bariatric endoscopists trained to perform endoscopic suturing using the Apollo Overstitch suturing device (Apollo Endosurgery).
