Background:
Little is known about training and the practice of vaginal hysterectomy in many sub-Saharan Africa countries.
Objective:
The aim of this study was to identify the clinical determinants of choice of hysterectomy route for benign conditions at the University Teaching Hospital in Yaoundé, Cameroon (UTHYC).
Methods:
This was a retrospective cross-sectional study at the UTHYC from January 1, 2000 to December 31, 2008. Non-emergency hysterectomies for benign conditions were divided into two surgical approaches: vaginal and abdominal. Patients' files and registers were used for data collection. Variables of interest were socio-demographic, reproductive health, and clinical characteristics, including indications and surgical route. Analysis was performed using Epi-Info version 3.5.1. Logistic regression analysis was conducted to determine the association between clinical variables and surgical routes. Odds ratios with their 95% confidence intervals (CI) were calculated. The level of significance was set up at P < 0.05.
Results:
One hundred and sixty-three women who underwent hysterectomy for benign conditions were included in the study. Thirty-seven (22.7%) were by vaginal route and 126 (77.3%) by abdominal route. Indications for hysterectomy were: cervical premalignant lesions, symptomatic uterine fibroids, prolapsed uterus, endometrial hyperplasia, recurrent cervical condyloma, and dysfunctional uterine bleeding. All 61 women with estimated uterine size of more than 12 weeks were operated on by abdominal route. At bivariate analysis, compared to women who had vaginal hysterectomy, factors associated with the choice of abdominal route were secondary/tertiary level of formal education, previous history of laparotomy/caesarean section, premenopausal status, age less than 50 years, and symptomatic uterine fibroids as surgical indication. At multivariate analysis, factors remaining independently associated with the choice of abdominal route were: age <50 years (AOR: 2.99 [1.9-4.71]), P < 0.001); previous laparotomy/cesarean section (AOR: 2.95[2.13-4.08], P = 0.001); premenopausal status (AOR: 1.55 [1.06-2.25]; P = 0.001); and myoma as surgical indication (AOR: 7.49.4[3.2-14.4]; P = 0.0001).
Conclusion:
Less than a quarter of hysterectomies for benign conditions were performed vaginally. All patients with uterine sizes larger than 12 weeks had laparotomy. The determinants of the choice of the abdominal route included age less than 50 years, previous laparotomy/caesarean section, premenopausal status, and fibroid as surgical indication.
