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

Answer options

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

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.
