Introduction/Background Knowing that diaphragmatic involvement must be resected surgically for optimal cytoreduction in primary peritoneal or ovarian cancer, we performed diaphragmatic curettage instead of resective surgery, with follow-up of the patients to know the specific sites of recurrent disease when it happens.

Methodology Fifteen patients with primary peritoneal or ovarian carcinoma with diaphragmatic involvement were subjected to diaphragmatic curettage (one or both diaphragms) with a big and sharp curette after liver mobilization as a part of cytoreductive surgery. Eleven (73.3%) patients had suspicious imaging of diaphragmatic involvement preoperative at CT scan. In ten patients with recurrent disease (66.6%), none had suspect of diaphragm involvement at CT scan or intraoperative during secondary cytoreduction.

Results In all 15 patients the curettage left diaphragms free of disease. In 10 patients with recurrent disease according to the CT scan and/or a secondary cytoreduction, diaphragms were free of disease.

Conclusion The diaphragmatic curettage is a safe and effective procedure to treat diaphragm involvement during cytoreductive surgery.
