Ultrasound of an indirect hernia containing fat, with testicle seen at right. T2 weighted MRI of the same case (done for another purpose), also demonstrating fat content. Ultrasound showing an indirect inguinal hernia [18] Incarcerated inguinal hernia [19] An indirect inguinal hernia results from the failure of embryonic closure of the deep ...
A small bowel obstruction as seen on CT Average inner diameters and ranges of different sections of the large intestine. [15] The main diagnostic tools are blood tests, X-rays of the abdomen, CT scanning, and ultrasound. If a mass is identified, biopsy may determine the nature of the mass. [citation needed]
This is a medical emergency, as the loss of blood supply to the bowel can result in necrosis (tissue death) followed by gangrene (tissue decay). This is a life-threatening condition requiring immediate surgery. [3] The term incarcerated femoral hernia is sometimes used, but may have different meanings to different authors and physicians.
Through the abdominal wall, organs inside the pelvis can be seen, such as the urinary bladder or the ovaries and uterus in women. Because water is an excellent conductor for ultrasound waves, visualizing these structures often requires a well-filled urinary bladder (this means the patients has to drink plenty of water before the examination).
The treatment of intestinal ischemia depends on the cause and can be medical or surgical. However, if bowel has become necrotic, the only treatment is surgical removal of the dead segments of bowel. [34] In non-occlusive disease, where there is no blockage of the arteries supplying the bowel, the treatment is medical rather than surgical ...
Barium X-ray examinations are useful tools for the study of appearance and function of the parts of the gastrointestinal tract. They are used to diagnose and monitor esophageal reflux, dysphagia, hiatus hernia, strictures, diverticula, pyloric stenosis, gastritis, enteritis, volvulus, varices, ulcers, tumors, and gastrointestinal dysmotility, as well as to detect foreign bodies.
The small bowel feces sign results from stagnation of enteric contents within dilated segments of the small intestine. [1] When intestinal motility is impaired due to obstruction, progressive dehydration of luminal contents occurs, leading to the formation of solid particulate matter that mimics feces. [ 3 ]
A Richter's hernia occurs when the antimesenteric wall of the intestine protrudes through a defect in the abdominal wall. This is distinct from other types of abdominal hernias in that only one intestinal wall protrudes through the defect, such that the lumen of the intestine is incompletely contained in the defect, while the rest remains in the peritoneal cavity.
