The right diaphragm peritoneum and its adjacent anatomical structures are commonly involved in advanced ovarian cancer. The most affected area and characteristic fluid dynamics of peritoneal fluid circulation form the substance of this presentation. In the past, right diaphragmatic involvement was one of major obstacles to achieving no macroscopic residual disease. Currently, it is well known that diaphragmatic procedures in advanced ovarian cancer are safe and feasible and do not increase long-term morbidity.1 2
On that basis surgeons performing advanced operations for ovarian cancer may contribute to better surgical and oncological outcomes if they have solid anatomic knowledge and competency in the diaphragmatic surgical procedures applied in ovarian cancer surgery.
Not every patient presents with a similiar extent of diaphragmatic involvement. In some patients tumorous implants may obliterate the hepatico-phrenic sulcus and spread extensively to adjacent structures, such as the Glissonian capsule. Typically, liver mobilization is performed through dissection of the hepatico-phrenic sulcus adjacent to the liver parenchyma. Obliteration and agglutination of the sulcus may cause more bleeding, disruption of tumor integrity, and scattering of tumor cells while the classic liver mobilization approach is tried.
By approaching retroperitoneally,3 without disturbing the hepatico-phrenic sulcus and Glissonian implants, the diaphragm can be stripped and resected with no physical contact through tumoral incision (Figure 1). In addition, bleeding and tumorous scattering can be minimized, and Glissonian implants can be eradicated retrogradely.
Subperitoneal carbon dioxide insufflation and towel-aided dissection may facilitate and accelerate the procedure.4
For a case of glissonectomy, we present some tips and anatomical landmarks for extraperitoneal diaphragmatic stripping and partial resection (Video 1).

Patient consent for publication
Ethics approval
This study involves human participants but did not require approval as cytoreductive procedures (various peritonectomies) are performed regularly in our department. As routine, written consent is obtained from every patient for using part or parts of surgical procedures for educational purposes. Participants gave informed consent to participate in the study before taking part.
