Resection of diaphragmatic peritoneum and muscle: role in cytoreductive surgery for ovarian cancer.
Fourteen patients undergoing primary cytoreductive surgery for stage III ovarian malignancies had diaphragmatic peritoneum, muscle, or both resected in an attempt to remove all metastatic disease greater than 0.5 cm in diameter. Resection was completed in 13 of 14 patients (93%), all obtaining optimal cytoreduction. Size of resected specimens varied from 12 x 7 to 17 x 11 cm. The mediastinum was entered in two patients. Four patients had resection of diaphragmatic muscle. All defects were closed primarily and a thoracostomy tube was placed. One patient who did not have muscle resection had a 30% pneumothorax that spontaneously resolved. No subdiaphragmatic hematomas or abscesses occurred. Time (mean 65 min, range 40-150 min) and blood loss (mean 175 ml, range 100-1500 ml) for the surgery depended upon extent of disease. One procedure was terminated due to bleeding from a lacerated liver capsule. We conclude that diaphragmatic peritoneum/muscle resection can be completed successfully with acceptable morbidity.
