Abstract:

Hyperplastic gastric polyps are typically benign and asymptomatic, often found incidentally during endoscopy. However, rare cases may present with bleeding, especially when polyps are large, ulcerated, or pedunculated. We report a 69-year-old male with melena and symptomatic anemia who was found to have a 3.6 cm ulcerated, pedunculated gastric polyp on endoscopy. The lesion was resected with a snare, and hemostasis was achieved with hemoclips. Pathology confirmed a hyperplastic polyp without dysplasia or malignancy. This case highlights the importance of considering bleeding polyps in the differential diagnosis of upper gastrointestinal (GI) bleeding and the dual diagnostic-therapeutic role of endoscopic resection.

Bleeding in Fresh Concrete

Bleeding in Fresh Concrete

Bleeding in fresh concrete occurs when water from the mix rises to the surface. This happens because the mix's solid components fail to retain all the water as they settle, leading to separation where water collects at the top. The severity of bleeding can be measured by assessing the total settlement or by noting the decrease in height per unit height of concrete.
Bleeding can cause several issues in the concrete structure. Sometimes, the rising water gets trapped beneath large aggregate...

Antipsychotic Drugs: Typical and Atypical Agents

Antipsychotic Drugs: Typical and Atypical Agents

Antipsychotic drugs are classified into first-generation (typical) drugs including phenothiazines; and second-generation (atypical) drugs. Chlorpromazine hydrochloride (Thorazine), a phenothiazine derivative, broadly impacts the central, autonomic, and endocrine systems. This drug, along with typical agents like haloperidol (Haldol), primarily works by antagonizing D2 receptors, thus reducing dopaminergic neurotransmission. However, typical antipsychotics can cause side effects such as sedation...

Anatomy of the Gastrointestinal System

Anatomy of the Gastrointestinal System

The human digestive system is an intricate and essential network for nutrient absorption and waste elimination. It encompasses the gastrointestinal (GI) tract and several accessory organs.
Here's a detailed walkthrough of this complex system:

Arteries of the Upper Limbs

Arteries of the Upper Limbs

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Gastrointestinal Motility Disorders

Gastrointestinal Motility Disorders

Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...

Histology of the Gastrointestinal (GI) Tract

Histology of the Gastrointestinal (GI) Tract

The GI tract, from beginning to end, is made up of four continuous tissue layers that adjust their structure according to their specific roles. These layers, from innermost to outermost, are known as the mucosa, submucosa, muscularis, and serosa, which are continuous with the mesentery.
The mucosa is sometimes called a mucous membrane due to its mucus-secreting features. This membrane is composed of epithelium, which directly interacts with ingested substances, and the lamina propria, a layer...
