anastomosis
Pronunciation: /əˌnæstəˈmoʊsɪs/
Surgical connection created between two tubular structures such as blood vessels or bowel segments.
Full Definition
An anastomosis is a surgically created connection between two hollow or tubular structures, commonly performed in oncologic surgery when portions of organs must be removed and continuity restored. Types include end-to-end, end-to-side, and side-to-side configurations, with selection based on anatomical constraints and functional requirements. In cancer surgery, anastomoses are frequently performed after bowel resections, vascular reconstructions, or urinary tract procedures. The integrity and healing of anastomoses are critical for successful outcomes and patient recovery.
Usage
Usage note: Plural is anastomoses; distinguish from anastomotic leak (complication) and angioplasty (vessel dilation).
