Summary
Acute lower gastrointestinal bleeding from the appendix is uncommon. This case report details a successful laparoscopic appendectomy for a patient with hematochezia due to solitary appendiceal bleeding.
Area of Science:
- Gastroenterology
- Surgical Oncology
Background:
- Acute lower gastrointestinal hemorrhage is a common clinical presentation.
- Appendiceal bleeding is an exceedingly rare cause of acute lower gastrointestinal hemorrhage.
Observation:
- A 42-year-old male presented with hematochezia.
- Abdominal computed tomography revealed active contrast leakage in the distal appendix.
- Colonoscopy identified active bleeding from the appendiceal orifice.
Findings:
- A solitary appendiceal bleeding source was identified.
- Laparoscopic appendectomy was performed for treatment.
- Postoperative follow-up showed no recurrence of hematochezia.
- Histopathological examination revealed eroded appendiceal mucosa and focal inflammation without vascular malformations.
Implications:
- This case highlights the appendix as a potential source of acute lower gastrointestinal bleeding.
- Laparoscopic appendectomy is an effective treatment for solitary appendiceal bleeding.
- Early diagnosis and surgical intervention can lead to favorable outcomes.

01:19Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
01:22Appendicitis-I: Introduction
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

01:27Peptic Ulcer
Peptic ulcers are erosive lesions of the gastric or duodenal lining, most commonly caused by Helicobacter pylori infection. This Gram-negative, helical bacterium has adapted to survive the stomach’s acidic environment by producing urease, which converts urea into ammonia and carbon dioxide. The ammonia neutralizes gastric acid in the bacterium’s immediate environment, allowing colonization of the gastric mucosa. H. pylori attaches to mucus-secreting epithelial cells, penetrates the mucus...
01:28Esophageal Varices-II: Clinical Features and Management
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.

01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

01:24Esophageal Varices-I: Introduction
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...
