A patient presents with an acute attack of cholelithiasis. Laboratory examination of the patient’s feces will show the following in this case:

Answer options

1. Positive reaction to stercobilin
2. Connective tissue
3. Negative reaction to stercobilin
4. Starch granules
5. Partially digested cellulose

Explanation

Cholelithiasis: blockage of the bile duct, hence bile (conjugated bilirubin) is not released in the duodenum, therefore stercobilin is not formed in the colon and is absent in feces.
