ABSTRACT

Objective: To report the experience of surgical caravans for urogenital fistulas care. Methodology: This was a retrospective study covering the period from January 2014 to December 2014 and which took place on 7 sites of fistula care. The epidemiological, anatomoclinical, therapeutic and evolutionary aspects were studied. Results: 346 patients were operated during 14 caravans. Their average age was 33.11 years (range: 12 to 70 years). Most of these patients were without remunerative activities (80%) and without education (63.3%). The average duration of fistula progression was 6.08 years (range: 0 to 42 years). Obstetrical etiology was predominant (87.9%). According to the classification of Kees Waaldijk, fistulas were divided into type I (67.4%), type II (21.1%), and type III (11.5%). The most common surgical approach was the transvaginal route (82.1%). The vesicovaginal splitting with separated suture of the bladder and the vagina was the basic technique (94.7%). The therapeutic results were judged after a follow-up of 1 month and 3 months. Across the cohort, 80 patients (23.1%) were lost of sight for follow-up at 1 month and 245 (70%) at 3 months. The success rates evaluated in patients reviewed at 1 month and 3 months were respectively 70% and 64%. Conclusion: The incidence of urogenital fistulas is still high in Côte d'Ivoire. Various anatomoclinical varieties have been identified and treated with satisfactory results in poorly equipped local structures.

1. Introduction

Uro-genital fistulas (UGF) are a solution of continuity between the urinary and genital tracts in women [1] [2] . In developing countries, the social exclusion they create, as well as the unsufficient provision of care linked in part to the lack of local expertise, have dramatic physical and psychosocial consequences for the patients-mostly very young-affected with UGF [2] [3] . In Côte d’Ivoire, the management of the UGF was done in specialized departments of the University Hospital Centers, which are difficult to access for these poor and rural patients [4] [5] . In order to widen the provision of care, the Ivorian authorities, since 2007 with the support of the United Nations Population Fund (UNFPA), have launched free local surgical caravans in rural areas. These caravans also help to train health professionals and provide the regions visited with technical equip- ment for the care and repair of UGF. The purpose of this work is to report the experience of these surgical caravans.

2. Methodology

This was a descriptive, retrospective study of a cohort of patients carriers of UGF operated during surgical caravans of 10 days between 1^st January 2014 and 31^st December 2014. These caravans were held in 7 care sites erected by the Ministry of Public Health in collaboration with the UNFPA. These sites were located within existing hospital structures, namely the University Hospital Center of Bouaké, and the Regional Hospital Centers of Bondoukou, Man, Gagnoa, Séguéla, Korhogo and San Pédro (Figure 1).

The care of the patients during each caravan was composed of:

・ A mobile team of three trainers: an expert surgeon of the Fistula project and two university professors (urologists and gynecologists-obstetricians);

・ Professionals to be trained (Gynecologists-obstetricians, surgeons, nursing specialists and midwives) from the visited site (“local team”) and other health regions.

Patients were pre-selected by local surgical teams and then assessed by the entire caravan team.

The preoperative evaluation included a complete clinical examination, uro- gynecological examination using valves with or without methylene blue to determine the site of the fistula. No paraclinic diagnostic tests were performed.

The variables studied were socio-demographic, clinical, therapeutic and evolutionary. On the clinical side, we used the classification of Kees Waaldijk [6] . It distinguishes 3 types of UGF:

・ Type 1 or simple vesico-vaginal fistula (VVF): located at a distance from the bladder neck that does not touch the sphincter;

・ Type 2 or VVF with lesion of the sphincter:

・ Type 2a or complex VVF: does not completely destroy the urethra

・ Type 2b or severe VVF: total lesion of the urethra

・ Type 3: other including combined forms.

The post-operative follow-up was carried out by the local medical team. Therapeutic results were assessed after 1 month and 3 months follow-up.

All patients with closed fistula (dry patients) with no sphincter disorders or

urinary incontinence were cured.

3. Results

3.1. Epidemiological Characteristics

During the study period, 346 patients affected with fistula were operated in 14 caravans, an average of 24.8 patients (range: 14 and 34) per caravan. Their average age was 33.11 (range: 12 - 70 years). The majority (73.4%) lived in rural areas. Illiterates and housewives accounted for 63.3% (n = 219) and 80% (n = 277) of the cohort 49.1% of the patients were divorced or abandoned by their families. One hundred and forty-five patients (41.9%) were residing in the host city of the caravan. The other 201 (58.1%) had to travel an average of 192 km (extremes: 39 and 696 km) from their place of residence to access the caravan site.

3.2. Clinical Characteristics

The average duration of fistula progression was 6.08 years (range: 0 to 42 years). Fistula has been evolving for more than 10 years in 265 patients (76.6%). 245 patients (70.8%) had no prior treatment. The etiology of the fistula was obstetricin 304 patients (Table 1). The average duration of labor was 2.3 days (range 0 - 5 days) and had a low vaginal delivery in 31.9%, caesarean section in 62.2% and hysterectomy in 5.9%.

Table 2 gives the type of UGF according to the Kees Waaldijk classification. The average fistula size was 1.2 cm (range: 0.1 - 6 cm).

3.3. Therapeutic Characteristics

At the therapeutic level, spinal anesthesia was performed in 329 patients (95.10%). The surgical route was vaginal in 82.1% of cases (284 patients), abdominal in 11.6% of cases (40 patients) and mixed in 6.3% of cases (22 patients). The vesico-vaginal splitting with suture separated from the bladder and vagina was the basic technique (94.7%; n = 328); 25 patients had a colposuspension. In 18 patients (5.3%), an exclusive ureteral reimplantation was performed to treat uretero-vaginal fistulae.

The average urinary catheter ablation time was 27.27 days (range: 14 - 30 days).

Of the total cohort, 80 (23.1%) patients were lost of sight to follow-up at 1 month and 245 (70%) at 3 months. The cure rates evaluated in patients reviewed at 1 month and 3 months were respectively 70% and 64%. Figure 2 shows the operative results according to the type of fistula at 1 month.

4.1. Epidemiological Characteristics

The cohort of this study was composed of 346 fistula patients operated in one

year in seven towns (Figure 1). These figures, which appear to be high, are not very representative of the real needs to be met in terms of repairing UGF in the subregion countries in general. Indeed in these countries which already had the experience of the fistula caravan, many fistula patients are not treated at every caravan either for lack of information or difficulties to access to the caravan site [7] [8] [9] . The surgical caravans have had the merit of widening the provision of care. Therefore they must be perpetuated and above all extended to all the regions of Côte d’Ivoire. However, they must quickly give way to the establish- ment of permanent services able to manage a greater number of fistula patients [10] . However, the biggest challenge remains the active identification of the many fistula patients living in the community who are hiding and who are unaware of the existence of treatment [1] [8] [11] . They should be informed of thehealing possibilities and directed towards the care sites. A large-scale awareness of policy makers, health professionals, non-governmental organizations, religious and community leaders would make it possible to find one large number.

Regarding the epidemiological profile of the fistula patients found in the series, it was not different from that reported by most African authors [2] [7] [8] [12] [13] [14] . They were young, poor, uneducated, residing in rural areas and abandoned by their spouses or their entourage.

4.2. Diagnostic Characteristics

The majority of the patients of this study had a fistula which evolved over 10 years (76.6%), and 70.8% of cases didn’t received any care. This observation shows the importance of uncovered needs for fistula repair in Côte d’Ivoire.

As for the occurrence mechanism, obstetric factors were the main causes (87.9%) of the cases we had cared for (Table 1). Many authors have also reported that obstetric factors were the main causes of fistula (around 90%) in developing countries because of the difficulties to access to emergency obstetric care [2] [7] [8] [11] [12] [13] [14] [15] .

According to the seriousness, Table 2 shows that complex fistulae were common in the study series (21.1%) and many african authors also described these complex forms in their articles [2] [8] [12] .

Moreover 67.4% of simple fistulae were found in this study (Table 2) which could be linked to selection bias. Indeed, the punctual nature of the caravans and the lack of equipment at the sites proved to be unsuitable for the management of complex forms requiring more means, more important surgery and prolonged follow-up.

4.3. Therapeutic Characteristics

The majority of fistulas (82.1%) were surgically accessible through vaginal route and spinal anesthesia (95.10%) was the most common type of anesthesia which permitted to minimize the cost of care. The most performed surgical technique was the vesicovaginal splitting with separated suture of the bladder and the vagina, without the addition of neighborhood structure (Figure 2). This techni- que was carried out on fistulous orifices of size varying between 0.1 and 6 cm. It has also been performed by Wall and Dekou when the orifices had a diameter of between 0.2 and 8 cm [16] [17] . Therapeutic results were judged after one month and three months follow-up. They are characterized by a significant number of lost of sight. These facts point to another challenge in evaluating therapeutic outcomes: the difficulty of monitoring the patients undergoing surgery. At 1 month the results were characterized by a high rate of failure in type II fistulas and a 70% success rate in types I and III, and were consistent with data from the literature [15] [18] [19] . The care of type II fistulae is marked by a high rate of failure in relation to post-cure urinary incontinence even when sealing is achieved [10] [12] [18] [19] . Different techniques are proposed to treat post fistula urinary incontinence [14] [18] [19] . Among these techniques, we performed colposuspension (25 cases), described by Waaldijk [6] . Although these techniques seem to produce interesting results, it is difficult to draw conclusions from this because of the difficult follow-up of patients over a long term [18] [19] . Moreover, the high cost of synthetic strips makes it impossible to afford them in developing countries [18] .

5. Conclusion

This study showed that the incidence of urogenital fistula in our country is underestimated. They are mostly of obstetric origin and their diagnosis was essentially clinical. Various anatomo-clinical varieties were identified. The majority was treated by the vesicovaginal splitting with separated suture of the bladder and the vagina, with satisfactory results in poorly equipped local structures. Therefore, the UNFPA’s policy aiming to reinforce capacities of health professionals for the treatment of UGF should be perpetuated.
