What is the Difference Between Anastomosis and Fistula?
🆚 Go to Comparative Table 🆚Anastomosis and fistula are two types of connections between different structures in the human body, but they have distinct differences:
- Anastomosis refers to a connection or link between two structures that usually diverge or branch. This connection can be normal or abnormal, natural or artificial, and can be present from birth or acquired over time. For example, a natural anastomosis is often seen in blood vessels, where it may occur between two arteries, two veins, or between an artery and a vein. Surgical anastomosis is done in segments of intestine or blood vessels either by stapling or sewing.
- Fistula is an abnormal connection between two structures, such as blood vessels, intestines, or other hollow organs. It is always abnormal and can be acquired or congenital. Fistulas usually occur between two internal organs or between an internal organ and a body surface. They can be caused by injury, surgery, infection, or inflammation.
In summary, anastomosis is a connection between two structures that can be either natural or surgically created, while a fistula is an abnormal connection between two structures that is always indicative of an abnormal condition.

Comparative Table: Anastomosis vs Fistula
Here is a table comparing the differences between anastomosis and fistula:
Feature | Anastomosis | Fistula |
---|---|---|
Description | A connection or attachment between two structures that are otherwise diverging. | An abnormal connection between two structures. |
Type | Can be normal or abnormal. | Is always abnormal. |
Occurrence | Can be natural, surgical, innate, or acquired. | Occurs due to injury, surgery, infection, or inflammation. |
Examples | Connection between two arteries, two veins, or an artery and a vein. | Connection between two segments of intestine after surgery. |
Anastomosis refers to a connection between two structures that are otherwise diverging, and it can be natural, surgical, innate, or acquired. A fistula, on the other hand, is an abnormal connection between two structures, which usually forms due to injury, surgery, infection, or inflammation.
