To determine which of the following is not a common disorder associated with the digestive system, we will analyze each option provided.

### Step-by-Step Solution:

1. **Identify the Options**: We need to look at the list of options provided in the question (though they are not explicitly mentioned here, we will assume they include tetanus, diarrhea, jaundice, and dysentery based on the transcript).

2. **Analyze Tetanus**:
- Tetanus is a medical condition characterized by prolonged contraction of skeletal muscle fibers.
- It is primarily a neurological disorder caused by a toxin produced by the bacterium *Clostridium tetani*.
- **Conclusion**: Tetanus is not associated with the digestive system.

3. **Analyze Diarrhea**:
- Diarrhea is defined as an abnormal frequency of bowel movements, often accompanied by increased fluidity of fecal discharge.
- It is a common digestive disorder that affects the absorption of food.
- **Conclusion**: Diarrhea is associated with the digestive system.

4. **Analyze Jaundice**:
- Jaundice is a condition that indicates liver malfunction, where bile is not excreted properly.
- It results in yellowing of the skin and eyes due to the accumulation of bile pigments in the blood.
- **Conclusion**: Jaundice is associated with the digestive system, as the liver is a crucial organ in digestion.

5. **Analyze Dysentery**:
- Dysentery is an inflammatory disorder of the intestine, particularly the colon, resulting in severe diarrhea that may contain blood and mucus.
- It is often accompanied by abdominal pain and fever.
- **Conclusion**: Dysentery is associated with the digestive system.

6. **Final Conclusion**:
- After analyzing all the options, we find that tetanus is the only condition that is not related to the digestive system.
- Therefore, the correct answer to the question is **tetanus**.
