Summary
Paradiverticulitis, minor bleeding from colonic diverticula, is a source of fecal occult blood. This study identifies three types of paradiverticulitis, clarifying its role in positive occult blood tests.
Area of Science:
- Gastroenterology
- Colorectal Surgery
Background:
- Colonic diverticula are known causes of massive gastrointestinal bleeding.
- The contribution of colonic diverticula to fecal occult blood loss remains poorly understood.
Purpose of the Study:
- To investigate the potential for minor bleeding from colonic diverticula and diverticulosis.
- To identify and characterize sources of fecal occult blood loss in patients with diverticula.
Main Methods:
- Retrospective analysis of 737 cases of colonic diverticula diagnosed between April 1989 and May 1994.
- Colonoscopic evaluation to identify sources of positive fecal occult blood tests.
- Prospective study of 595 diverticula cases over two years.
Main Results:
- Thirty-seven cases (5%) of diverticula were identified as sources of positive occult blood tests.
- Three types of bleeding were identified: intradiverticular, peridiverticular, and interdiverticular.
- Prospective study identified 67 cases (11.3%) of paradiverticulitis.
Conclusions:
- Paradiverticulitis, encompassing bleeding from intradiverticulitis, peridiverticulitis, and interdiverticulitis, is a significant cause of fecal occult blood loss.
- This research clarifies the role of colonic diverticula in minor gastrointestinal bleeding.

01:25Endocarditis II: Clinical Features of Infective Endocarditis
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
01:22Pericarditis I: Introduction
Pericarditis is defined as the inflammation of the pericardium, the thin, sac-like membrane surrounding the heart. This condition can cause significant chest pain and other symptoms, often necessitating medical intervention. The pericardium has two layers: the inner visceral layer and the outer parietal layer, separated by a small amount of fluid that reduces friction during heartbeats.Types of PericarditisPericarditis can be classified into several types based on the duration and nature of the...
01:19Pericarditis II: Clinical Features and Diagnostic Tests
Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...
01:18Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
01:19Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
01:27Diverticular Disease of the Colon
Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...
