ORLANDO – Intraoperative and serious postoperative adverse events do not occur more frequently with concurrent urogynecologic and gynecologic oncology procedures versus the latter alone, but minor adverse events are more common, according to findings from a retrospective matched cohort study.
The study also showed that 10% of planned urogynecologic procedures are modified or abandoned at the time of gynecologic oncology surgery, Emily R. Davidson, MD, reported at the annual scientific meeting of the Society of Gynecologic Surgeons.
Intraoperative complications occurred in 10% of the 108 case patients and 216 matched controls undergoing only gynecologic oncology procedures, and included visceral injury, intraoperative transfusion, and estimated blood loss of 500 mL or more; the complication rates did not differ between the groups, said Dr. Davidson, a fellow at the Cleveland Clinic.“Concurrent cases were longer by 76 minutes, which is not surprising given that additional procedures were performed, and on univariate analysis there were differences in the frequency of multiple postoperative adverse events between the cohorts, including estimated blood loss, discharge with a Foley catheter, perioperative transfusion, postoperative pulmonary complications, ileus, renal failure, and urinary tract infection,” she said.
However, on multivariate analysis controlling for preoperative cardiovascular and pulmonary comorbidities, only urinary tract infection and discharge with a Foley catheter related to postoperative voiding dysfunction, which were significantly more common in the combined surgery group (26% vs. 7% and 35% vs. 1%, respectively), remained significantly different between the groups, she noted.
No differences were seen between the groups in length of hospital stay, reoperation, readmission within 1 month, surgical site infection, or death within 1 year of surgery, but patients undergoing concurrent procedures had more Clavien-Dindo grade 2 complications (44% vs. 19%), and this was primarily related to the prescription of antibiotics for urinary tract infections, she said.
As for the 11 cases (10%) with planned urogynecologic surgeries that were significantly changed or aborted at the time of gynecologic oncology surgery, 5 were because of intraoperative complications, 3 because of technical limitations, and 3 because of a change in oncologic care plan, including the need for postoperative radiation, she noted.
