Surgical procedures and morbidities of diaphragmatic surgery in patients undergoing initial or interval debulking surgery for advanced-stage ovarian cancer.

摘要

BACKGROUND: Surgical management of advanced-stage ovarian cancer (ASOC) can require diaphragmatic surgery (DS) to achieve complete cytoreduction. The aim of this study was to evaluate modalities and morbidities of DS at the time of initial surgery (INS) and interval debulking surgery (IDS; performed after neoadjuvant chemotherapy). STUDY DESIGN: Retrospective review of patients undergoing (unilateral or bilateral) DS at the time of INS or IDS for ASOC. RESULTS: Between 2005 and 2008, 63 patients were studied. Treatment of the diaphragm was unilateral in 31 patients and bilateral in 32 patients. DS was performed respectively at the time of INS in 22 patients (35%) and IDS in 41 (65%) patients. Complete cytoreductive surgery was achieved in 95% (21 of 22 in the INS group and 39 of 41 in the IDS group). Surgical procedures used during DS were (in the INS and IDS groups, respectively) stripping in 14 (64%) and 16 (39%), coagulation in 2 (9%) and 10 (24%), and both procedures in 6 (27%) and 15 (37%). An intraoperative chest tube was placed in 14% of patients in each group. Postoperative chest complications requiring treatment occurred in 6 cases: pulmonary embolism (3 cases), symptomatic pleural effusion requiring chest drainage (1 case), and pneumothorax necessitating chest drainage (2 cases). CONCLUSIONS: Rate of overall morbidity related to DS was not statistically different in patients undergoing INS and IDS. Surgical treatment of this upper part of the abdomen is key to achieving complete cytoreductive surgery in ASOC.
