Effect of laparoscopic versus abdominal radical hysterectomy on major surgical complications in women with stage IA-IIB cervical cancer in China, 2004–2015

Abstract

ObjectivesTo report the trends in surgical approaches and compare the major surgical complication rates of laparoscopic and abdominal radical hysterectomy for cervical cancer. MethodsFrom the major surgical complications of cervical cancer in China (MSCCCC) database, we obtained the demographic, clinical, treatment hospital and complication data of patients with cervical cancer who underwent radical hysterectomy from 2004 to 2015 at 37 hospitals. The patients were assigned to the laparoscopic and abdominal surgery groups. The differences in the complication rates were analyzed using univariate and multivariable logistic regression models. ResultsWe identified a total of 18447 patients; 5491 (29.8%) underwent laparoscopic surgery and 12956 (70.2%) underwent abdominal surgery. The proportion of laparoscopic surgery rose from 0.35% in 2004 to 49.31% in 2015. In the multivariate analysis, the laparoscopic group had increased odds of intraoperative and postoperative complications (OR = 3.88, 95% CI = 2.47–6.11; OR = 1.42, 95% CI = 1.11–1.82). A more detailed analysis showed that laparoscopic surgery was associated with increased rates of intraoperative ureteral injury (OR = 3.83, 95% CI = 2.11–6.95), bowel injury (OR = 14.83, 95% CI = 1.32–167.25), vascular injury (OR = 3.37, 95% CI = 1.18–9.62), postoperative vesicovaginal fistula (OR = 4.16, 95% CI = 2.08–8.32), ureterovaginal fistula (OR = 4.16, 95% CI = 2.08–8.32), rectovaginal fistula (OR = 8.04, 95% CI = 1.63–39.53), and chylous leakage (OR = 10.65, 95% CI = 1.18–95.97), while abdominal surgery was more likely to cause bowel obstruction (OR = 0.55, 95% CI = 0.35–0.87). The two groups had similar rates of bladder injury, obturator nerve injury, pelvic hematoma, rectovaginal fistula and venous thromboembolism (P > 0.05). ConclusionLaparoscopic surgery was associated with more major surgical complications, especially intraoperative ureteral injury and postoperative fistula, than abdominal surgery among women with cervical cancer.
