Evidence Basis for Hysterectomy

National trends and determinants of hospitalization for uterine leiomyomas - Portuguese public database analysis from 2000 to 2015

OBJECTIVE

To determine the trends of hospitalization (inpatients and outpatients) for uterine leiomyomas in Portugal, over a period of fifteen years.

STUDY DESIGN

We perform a population- and register-based retrospective study of women who were hospitalized with a primary diagnosis of uterine fibroid in public hospitals in continental Portugal, in the period between January 1, 2000 and December 31, 2015. Patient data regarding hospital codes, admission and discharge dates, patient age, diagnosis, procedures and complications were extracted from the national database of Administração Central do Sistema de Saúde (ACSS). All calculations were performed with the STATA software, version 13.1. Categorical data were analysed by the χ2 test and the means of continuous variables were analysed with Student's t-test. Statistical significance was set at p < 0.05.

RESULTS

Between 2000 and 2015, 102 476 patients were admitted to public hospitals in Portugal due to uterine leiomyomas. The majority were admitted to hospital for surgery: 73.6 % for hysterectomy and 13.0 % for myomectomy. During this period, the definitive treatment (hysterectomy) decreased from 83.2% to 63.0% (p < 0.001), with a change towards more conservative treatments such as myomectomies (6.4% to 22.6%, p < 0.001). Additionally, in women submitted to hysterectomy, laparoscopic and vaginal routes increased (1.1%-11.5%, p < 0.001 and 2.1%-4.0%, p < 0.001; respectively). Globally, there was a 14.3 % reduction in hospitalizations due to uterine fibroids and an increase in the outpatient rate (from 3.1% to 22.1%). The mean number of hospitalization days for inpatients also decreased (from 6.3 ± 4.1-4.0 ± 3.0, p < 0.001). Regarding urgently hospitalized women, 11.8 % required a blood transfusion. In women submitted to surgical procedures, 0.5 % had an intraoperative complication and 2.3 % a post-operative complication, directly related to the surgical procedure.

CONCLUSION

There was a reduction in hospitalizations due to uterine fibroids and a change towards more conservative treatments.

Overcoming barriers to vaginal hysterectomy: An analysis of perioperative outcomes

Objective

To determine perioperative outcome differences in patients undergoing vaginal hysterectomy based on uterine weight, vaginal delivery, and menopausal state.

Material and Methods

Retrospective chart review of 452 patients who underwent vaginal hysterectomy performed by a single surgeon. Patients’ age, vaginal delivery, uterine weight, previous pelvic surgery, previous cesarean delivery, removal of ovaries were compared, as well as estimated blood loss (EBL), operating room time (ORT), length of stay, intraoperative complications and postoperative complications. Multivariable logistic regression was used, and all data were analyzed at the level of p<0.05 statistical significance using SAS system software (SAS Institute Inc., Cary, NC), version 9.3.

Results

The mean age was 57.13±11.52 years and the median vaginal delivery was 2. The uterine weight range was 16.6-1174.5 g (mean 169.79±183.94 g). The incidences of blood transfusion and bladder injury were 3.03% and 0.66%, respectively. Factors shown to be associated with longer ORT included greater uterine weight, removal of ovaries, posterior repair, tension-free vaginal tape sling, prolapse, and EBL >500 mL (p<0.001). The factors associated with EBL >500 mL were greater uterine weight (p=0.001), uterine myomas (p=0.016) and premenopausal state (p=0.014). The factors associated with conversion to laparotomy were greater uterine weight (p<0.001) and premenopausal state (p<0.001).

Conclusion

Vaginal hysterectomy is a safe and feasible approach for patients desiring hysterectomy regardless of uterine weight and vaginal delivery.
