Summary
Ultrasonography (US) can identify right-sided colonic diverticulitis. Key US findings include wall thickening and echogenic material, aiding differentiation from appendicitis and preventing unnecessary surgery.
Area of Science:
- Gastroenterology
- Radiology
- Abdominal Imaging
Background:
- Right-sided colonic diverticulitis is less common than left-sided.
- Accurate diagnosis is crucial to differentiate from appendicitis.
Purpose of the Study:
- To evaluate ultrasonography (US) findings in patients with right-sided colonic diverticulitis.
- To identify characteristic US features for diagnosis.
Main Methods:
- Retrospective analysis of 14 patients with right-sided colonic diverticulitis diagnosed by US.
- Documentation of demographic data, clinical features, and US imaging characteristics.
Main Results:
- Common symptoms included right lower abdominal tenderness, leukocytosis, and fever.
- US findings revealed diverticular wall thickening, surrounding echogenic fat, and intradiverticular echogenic material in 50% of cases.
- Complications included abscess formation (14.3%) and perforation (7.1%); most patients (85.7%) were treated conservatively.
Conclusions:
- Characteristic US features of right-sided colonic diverticulitis include wall thickening, surrounding echogenic fat, and intradiverticular echogenic material.
- Recognizing these US findings aids in differentiating diverticulitis from appendicitis.
- Accurate US diagnosis may help avoid unnecessary emergent surgery.

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.

Appearance is a multidimensional aspect of self-presentation that encompasses observable attributes such as clothing, grooming, speech, and nonverbal behavior. These elements are often strategically managed to align with socially constructed expectations in different settings. For instance, individuals tailor their appearance during job interviews, social gatherings, or athletic events to meet the perceived norms of those environments.Contextual Adaptation and Social SignalsThe research...

1.9K
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
