ABSTRACT
OBJECTIVE: To investigate long-term and patient-reported outcomes, including sexual function, in women undergoing urogenital fistula (UGF) repair, addressing the lack of such data in Western countries, where fistulas often result from iatrogenic causes. PATIENTS AND METHODS: We conducted a retrospective analysis at a tertiary referral centre (2010-2023), classifying fistulas based on World Health Organisation criteria and evaluating surgical approaches, aetiology, and characteristics. Both objective (fistula closure, reintervention rates) and subjective outcomes (validated questionnaires) were assessed. A scoping review of patient-reported outcome measures in UGF repair was also performed. RESULTS: The study included 50 patients: 17 (34%) underwent transvaginal and 33 (66%) transabdominal surgery. History of hysterectomy was present in 36 patients (72%). The median (interquartile range [IQR]) operating time was 130 (88-148) min. Fistula closure was achieved in 94% of cases at a median (IQR) follow-up of 50 (16-91) months and reached 100% after three redo fistula repairs. Seven patients (14%) underwent reinterventions for stress urinary incontinence after transvaginal repair (autologous fascial slings). Patient-reported outcomes showed median (IQR) scores on the International Consultation on Incontinence Questionnaire Female Lower Urinary Tract Symptoms Modules (ICIQ-FLUTS) of 5 (3-7) for filling symptoms, 1 (0-2) for voiding symptoms and 4.5 (1-9) for incontinence symptoms. The median (IQR) score on the ICIQ Female Sexual Matters Associated with Lower Urinary Tract Symptoms Module (ICIQ-FLUTSsex) was 3 (1-5). The median (IQR) ICIQ Satisfaction (ICIQ-S) outcome score and overall satisfaction with surgery item score was 22 (18.5-23.5) and 10 (8.5-10), respectively. Higher scores indicate higher symptom burden and treatment satisfaction, respectively. Our scoping review included 1784 women, revealing mixed aetiology and methodological and aetiological heterogeneity, thus complicating cross-study comparisons. CONCLUSIONS: Urogenital fistula repair at a specialised centre leads to excellent outcomes and high satisfaction. Patients with urethrovaginal fistulas are at increased risk of stress urinary incontinence, possibly due to the original trauma site of the fistula.
ABSTRACT
BACKGROUND: Loiasis is a highly prevalent helminth infection found in distinct regions of sub-Saharan Africa. The disease has been considered to be of minor clinical significance, but this belief is being increasingly challenged by recent evidence. We aimed to prospectively quantify the overall burden of disease caused by loiasis in an endemic region of Gabon, using disability-adjusted life years (DALYs). METHODS: We did a cross-sectional survey during 2017 and 2018 in rural Gabon. Volunteers underwent diagnostic tests for loiasis and were given a standardised questionnaire on symptoms. Participants reporting eye worm migration or harbouring Loa loa microfilariae were defined as loiasis positive. Morbidity-based DALYs associated with loiasis were estimated for the rural population of Gabon. FINDINGS: Between Sept 1, 2017 and May 31, 2018, 1235 participants residing in 38 villages in the Gabonese departments of Tsamba-Magotsi and Ogooué et des Lacs were screened. 626 (50·8%) of 1232 eligible participants had loiasis. 520 (42·2%) of 1232 participants reported eye worm migration. 478 (93·9%) of 509 individuals with eye worm migration also reported associated pain, and 397 (78·6%) of 505 reported vision disturbances. After correcting for age and sex, loiasis was significantly associated with a variety of symptoms, including transient painful oedema (adjusted odds ratio 1·76 [95% CI 1·37-2·26]) and arthralgia (1·30 [1·01-1·69]). Application of attributable fractions of correlating symptoms resulted in 412·9 (95% CI 273·9-567·7) morbidity-based DALYs per 100â000 people in rural Gabon. INTERPRETATION: Loiasis, with the pathognomonic sign of eye worm migration, appears to not be benign, but severely impeding to affected individuals. Furthermore, loiasis is associated with substantial morbidity, comparable to that of other neglected tropical parasitic diseases. These findings call for reconsideration of L loa as a relevant pathogen in affected populations, with a need for more concerted research and control of these infections.
