An incomplete fistula refers to a condition where a passage or connection between two body parts or organs is partially formed or unfinished. There are various synonyms that can be used to describe this medical condition. One such term is "imperfect fistula", which signifies that the connection is not entirely formed or functioning correctly. Another synonym is "partial fistula", indicating that only a portion of the expected passage has developed. Additionally, the term "uncompleted fistula" can be used to describe this condition, emphasizing that the connection remains unfinished or unresolved. These synonyms help medical professionals communicate and diagnose cases of an incomplete fistula, enabling appropriate treatment and management.
