Background:
Following blunt abdominal trauma, bowel injuries are often missed on admission computed tomography (CT) scan.
Methods:
Multicenter retrospective analysis of 176 adults with moderate-critical blunt abdominal trauma and admission CT scan who underwent operative exploration. Patients with a bowel injury missed on CT (n = 36, 20%) were compared to all other patients (n = 140, 80%).
Results:
The missed injury group had greater incidence free fluid without solid organ injury on CT scan (44% vs. 25%, p = 0.038) and visceral adhesions (28% vs. 6%, p = 0.001). Independent predictors of missed bowel injury included prior abdominal inflammation (OR 3.74, 95% CI 1.37-10.18), CT evidence of free fluid in the absence of solid organ injury (OR 2.31, 95% CI 1.03-5.19) and intraoperative identification of visceral adhesions (OR 4.46, 95% CI 1.52-13.13).
Conclusions:
Patients with visceral adhesive disease and indirect evidence of bowel injury on CT scan were more likely to have occult bowel injury.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Inflammatory Bowel Disease I: Ulcerative Colitis
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...
