B.
Ribbon-like stools.
C.
Hard stools positive for guaiac.
D.
“Currant jelly” stools.
The correct answer and Explanation is :
The correct answer is:
D. “Currant jelly” stools.
Explanation
Intussusception is a serious condition where a part of the intestine telescopes into an adjacent segment, leading to obstruction. This condition is most common in children but can also occur in adults. One of the hallmark signs of intussusception is the presence of “currant jelly” stools.
“Currant jelly” stools are characterized by their red or maroon color and mucous-like consistency, resembling the appearance of currant jelly. This stool type results from the combination of blood and mucus. The blood comes from the damaged and eroded blood vessels in the affected area of the intestine, and the mucus is produced as the intestine becomes inflamed and irritated.
This type of stool is significant because it reflects the underlying pathology of intussusception. As the telescoping of the intestine progresses, it causes ischemia (reduced blood flow) and necrosis (tissue death) of the affected bowel segment. The resultant bleeding and mucus production contribute to the characteristic “currant jelly” appearance of the stool.
In contrast:
- Loose, foul-smelling stools (Option A) are more indicative of infections or gastrointestinal disturbances rather than intussusception.
- Ribbon-like stools (Option B) might suggest a bowel obstruction but are more commonly associated with conditions like colorectal cancer rather than intussusception.
- Hard stools positive for guaiac (Option C) typically indicate the presence of occult blood and are more suggestive of chronic bleeding or hemorrhoids rather than the acute, acute symptoms of intussusception.
Recognizing “currant jelly” stools in a patient can be crucial for the timely diagnosis and treatment of intussusception, as this condition requires prompt medical intervention to prevent severe complications such as bowel necrosis or perforation.
