The incidence of major complications after the performance of extensive upper abdominal surgical procedures during primary cytoreduction of advanced ovarian, tubal, and peritoneal carcinomas.

Objective: To assess the morbidity and mortality associated with extensive upper abdominal surgery (EUAS) performed during primary cytoreduction for advanced ovarian carcinoma.
Methods: We identified all patients who underwent EUAS during primary cytoreduction for advanced ovarian, tubal, or peritoneal cancer at our institution from 1/01 to 12/06. Major grade 3-5 complications were those that led to invasive radiologic intervention, re-operation, unplanned ICU admission, chronic disability, or death within 30 days of surgery.
Results: There were 141 eligible patients, with a median age of 60 years (range, 38-82). The majority of patients had stage IIIC disease, 103 (73%); serous histology, 131 (93%); and ascites, 118 (84%). There were 229 EUAS procedures performed-diaphragm peritonectomy, 101 (72%); splenectomy, 45 (32%); full-thickness diaphragm resection, 19 (14%); partial hepatectomy, 18 (13%); distal pancreatectomy, 17 (12%); cholecystectomy, 15 (11%); and resection of porta hepatis tumor, 14 (10%). Cytoreductive outcomes were: no gross residual, 42 (30%); residual ≤ 1cm, 85 (60%); and residual >1cm, 14 (10%). Grade 3-5 complications occurred in 31 (22%) patients, including 2 mortalities (1.4%). In 21/31 (68%), the complication was successfully managed with percutaneous drainage of infected or non-infected collections. Overall median survival for all patients was 57 months.
Conclusions: Rates of major morbidity and mortality following EUAS for primary cytoreduction were 22% and 1.4%, respectively. Approximately two-thirds of complications were readily managed by percutaneous drainage of collections. With an overall median survival of 57 months in a cohort of patients with a large tumor burden, this rate of morbidity and mortality appears acceptable.
