The Palanivelu hydatid system (PHS) is a recently described device to remove the internal contents and the endocyst without excising the entire cyst.
The communicating type consists of a tear of the endocyst with escape of contents via biliary radicles or bronchioles.
Within the pericyst lies the external layer of the cyst itself (ectocyst) and the inner germinative membrane or the endocyst.
