It is the most common gynaecological surgery in the world. Objective: To describe the epidemio-clinical and prognostic aspects of gynaecological hysterectomies. Patients and methods: This was an 18-month retrospective prospective descriptive study with a six-month follow-up period from 1 December 2020 to 31 May 2022 carried out in the gynaecology department of the Segou regional hospital. Results: Fifty-six (56) hysterectomies were performed out of 118 gynaecological surgical procedures (47.45%). The mean age was 47 ± 11.77 years. Large multiparous women were the most common (50%), with an average parity of 4.58. The main indications were uterine fibroids (30.4%), precancerous lesions of the cervix (17.85%) and uterine prolapse (17.85%). The abdominal route was the most commonly used surgical route (82.14%). Hysterectomy was total in 100% of cases and associated with bilateral adnexectomy in 48.2% of cases. The intra- and post-operative prognosis was satisfactory in 94.6% of cases. No deaths were recorded. The average length of stay was 3.28 days, irrespective of the surgical approach. Three cases of dyspareunia were noted among those who had resumed sexual activity.展开更多

Surgery is the primary treatment modality when the disease is diagnosed at early stage. Radical hysterectomy in cervical cancer has not been evaluated in recent years in Cameroon. The purpose of this study is thus to evaluate the epidemiological and clinical features and short term outcomes of patients who underwent surgery. Patients and methods: This retrospective study was conducted at the Douala Gynaeco-obstetric and Pediatric Hospital and the Douala General Hospital. Cervical cancer patients who underwent Radical hysterectomy between January 2015 and December 2020 were included. A pre-established data collection tool was used to record socio-demographic, clinical and outcomes information from patients’ files;additional outcome information was obtained from phone calls. Descriptive analysis was done using the SPSS version 26. Bivariate analysis was used to determine associations between disease and patients characteristics and occurrence of adverse postoperative outcome. P value of 0.05 was considered. Results: Sixty one patients were enrolled. Their ages ranged from 33 to 74 years with a mean age of 51.95 ± 10.29 years. Over 85% of women were married, 65.57% were unemployed and 86.88% were multiparous. Only 28% had never done cervical cancer screening. Most patients had stage IB1 to IB2 stage disease (57.1%). Less than 9% underwent radical hysterectomy and 8 of those (13.11%) suffered intraoperative complications. Twenty-five patients (40.98%) presented immediate and short term complications. There was no significant association between the disease or patients’ characteristics and adverse outcomes. Conclusion: Cervical cancer patients are relatively young in our settings and only 9% of them reach the hospital at early stage. Postoperative adverse outcomes rate is higher than that reported in the literature. Sensitization on screening and awareness of early symptoms can reverse the situation.展开更多

Objective: The objective of this study was to determine the incidence, socio-demographic profile of patients, indications, management and maternal-fetal outcomes of EOH in a maternity hospital with limited resources in Niger. Methodology: This was an eight-year retrospective cohort study involving the analysis of medical records from patients who underwent emergency obstetric hysterectomies between 1 January 2015 and 31 December 2022 at the Mother and Child Health Centre (MCHC) in Maradi, Niger. The epidemiological data, indications, and outcomes of EOH were collated and subjected to analysis using the statistical software package SPSS 21.0. Comparisons were made using the Chi-squared test. A p-value of less than 0.05 was considered statistically significant. Results: During the study period, 239 cases of emergency obstetric hysterectomy were recorded out of 269,710 deliveries, representing a frequency of 0.89%. The mean age of the patients was 32.41 years (range: 17 - 50 years). The patients were identified as married (239 cases, 100%), unemployed (228 cases, 95.4%), and not attending school (215 cases, 90%). The largest number of cases were observed in large multiparous women (i.e., those with more than five children), representing 58.6% of the total number of cases (140 patients). The average parity among this group was 6.15 children. The majority of patients (229 patients, 95.82%) had undergone in utero transfer, with 169 patients (70.71%), originating from peripheral maternity units in the Maradi region. Upon admission, 116 patients (48.53%) exhibited active genital haemorrhage, while 58 patients (24.26%) were in shock. The primary indications for hysterectomy were uterine rupture (153 patients, 64%), uterine atony (77 patients, 32.2%), and placental accreta (six patients, 2.5%). Hysterectomy was performed by an obstetric gynaecologist (230 patients, 96.2%), an obstetric gynaecology resident (six patients, 2.5%), or a general practitioner with district surgical expertise (three patients, 1.3%). In the majority of cases (180 patients, 75.3%), total hysterectomy was performed. The incidence of maternal mortality (26 patients, 10.9%), and perinatal mortality (223 newborns, 93.4%) was notably elevated in our series. Conclusion: Our findings are in close alignment with those previously documented in the literature. The practice of emergency obstetric hysterectomy is a common occurrence in our region. It is considered a last resort when conservative procedures have failed or are not an option. Improved obstetric management would result in a reduction in the number of cases of haemostatic hysterectomy. The availability of blood products is expected to improve maternal prognosis.展开更多

In ...Obstetric hysterectomy is a surgical procedure most often performed in a context of extreme emergency in an obstetric environment. The incidence of obstetric hysterectomy is differently expressed around the world. In the CHU-SO maternity ward, hemorrhagic obstetric emergencies are common. The extreme urgency in which patients are admitted, the insufficiency of the technical platform, associated with the challenge of the availability of blood products, often leads to performing an obstetric hysterectomy for hemostasis. It is responsible for high maternal morbidity and mortality. Since 2000 no study has been carried out on this practice in the service. Objective was to describe the practice of obstetric hysterectomy at the CHU-SO and specifically to determine the prevalence, the prognostic factors to be able to act to reduce maternal mortality. Method: A descriptive, cross-sectional, and analytical study was carried out at the Gynecology-Obstetrics clinic of the CHU-SO;from January 1, 2021, to June 30, 2022. All hysterectomies performed in an obstetric emergency context (during pregnancy, perpartum or postpartum) in the department were included in our study. We did not include cases of obstetric hysterectomies outside the SO hospital or planned non-obstetric hysterectomies. Results: We recorded 75 cases of obstetric hysterectomy and 15,625 deliveries (0.48%). The average age was 32.89 ± 5.93. The age group between 30 and 35 years old was the most affected with a rate of 37.33%. Labor and third trimester hemorrhage were the main reasons for admission, patients were referred in 80% of cases. The average parity was 3.25 ± 1.92 with utmost of 0 and 11. The pauciparous (41.67%) and multiparous (32%) were the most affected. The indications frequently found were uterine atony (44%);uterine rupture (33.33%). Subtotal inter adnexal hysterectomy was performed in 94.67%. General anesthesia practiced in 69%. They were all polytransfuses. Three poor prognostic factors were observed during our study, namely: uterine atony;the state of hemodynamic shock before the operation;lack of blood transfusion. The maternal death rate was 21.33%. Conclusion: Obstetric hysterectomy is a very mutilating and complicated surgical procedure and is still common practice in Africa. The maternal prognosis is still reserved with a very high mortality rate in Togo.展开更多
