Ethical aspects of urinary diversion for women with irreparable obstetric fistulas in developing countries

Mainz II urinary diversion in low-resource settings: patient outcomes in women with irreparable fistula in Malawi

BACKGROUND

Obstructed labor leading to a vesicovaginal fistula remains a devastating outcome of childbirth in low-resource countries. Women with an irreparable vesicovaginal fistula may be candidates for a urinary diversion, such as the Mainz II modified ureterosigmoidostomy procedure. Previous reviews state that the procedure should be considered in low-resource countries. However, given the limited duration of postoperative follow-up, these studies do not adequately represent the long-term morbidity and mortality that is likely associated with this procedure. We present data that strongly support avoiding the procedure in low-resource countries.

OBJECTIVE

This study aimed to evaluate the postoperative status of the patient (dead, alive, lost to follow-up) and time to death following the Mainz II procedure.

STUDY DESIGN

This is a case series including 21 patients who underwent a Mainz II urinary diversion from April 2013 to June 2015 for management of irreparable vesicovaginal fistula at the Fistula Care Centre in Lilongwe, Malawi. Patients were seen postoperatively at 3, 6, 9, and 12 months, followed by every 6 to 12 months thereafter. Descriptive statistics were performed to summarize the data.

RESULTS

During the postoperative period, 8 (38.1%; 8/21) patients died, 5 (23.8%; 5/21) were lost to follow-up, and 8 (38.1%; 8/21) are currently alive and followed up at the Fistula Care Centre. We strongly suspect that 7 of the 8 deaths were related to the procedure given that the patients had illnesses that exacerbated the metabolic consequences of the procedure. The eighth patient died after being attacked by robbers. Unfortunately, the exact cause of death could not be determined for these patients. Given that most of the suspected illnesses would be treatable in an otherwise healthy patient, even in this low-resource setting, we surmised that the metabolic compromise from the Mainz II procedure likely contributed to their untimely death. The average time from procedure to death was 58 months, with the earliest death at 10 months and the most recent at 7 years after the procedure.

CONCLUSION

The Mainz II procedure is an option for patients with irreparable fistula. However, it should likely not be performed in low-resource countries given the long-term complications that often cannot be adequately addressed in these settings, leading to significant morbidity and mortality.

Complex circumferential obstetric fistula-a urologist's worst nightmare

INTRODUCTION AND HYPOTHESIS

Circumferential vesicourethrovaginal fistula is a severe form of obstetric injury that is challenging to repair and carries a poor prognosis related to eventual continence. Here, we report the successful repair of a circumferential vesicovaginal fistula associated with near total loss of the urethra. The use the anterior bladder flap technique along with an autologous rectus sheath sling resulted in the creation of an effective continence unit.

METHODS

A 31-year-old woman had a history of obstructed labor resulting in intrauterine death followed by trans-abdominal hysterectomy for postpartum hemorrhage. Since then she had had total urinary incontinence. She had an attempted repair through the vaginal route, which had failed. Physical examination and endoscopic evaluation revealed a large vesicourethrovaginal fistula with near total loss of the urethra leaving only the meatus. Intraoperatively, we found that it was a large circumferential defect in the infratrigonal region with no anterior bladder wall left at the site of the fistula.

RESULTS

We performed an anterior bladder flap procedure as described by Tanagho along with an autologous rectus sheath sling for additional support. Postoperatively, the patient was completely continent.

CONCLUSIONS

The anterior bladder onlay flap technique, which has been used extensively for female urethral reconstruction in developed countries, along with an autologous rectus sheath sling is an effective technique for management of circumferential fistulas allowing good continence. Incorporation of this technique into the armamentarium of surgeons managing fistulas in developing countries will go a long way toward helping this unfortunate group of women with this morbid complication of obstructed labor.

Ethical considerations in global surgery: a scoping review

Introduction

An unmet burden of surgical disease exists worldwide and is disproportionately shouldered by low-income and middle-income countries (LMICs). As the field of global surgery grows to meet this need, ethical considerations need to be addressed. Currently, there are no formal guidelines to help inform relevant stakeholders of the ethical challenges and considerations facing global surgical collaborations. The aim of this scoping review is to synthesise the existing literature on ethics in global surgery and identify gaps in the current knowledge.

Methods

A scoping review of relevant databases to identify the literature pertaining to ethics in global surgery was performed. Eligible articles addressed at least one ethical consideration in global surgery. A grounded theory approach to content analysis was used to identify themes in the included literature and guide the identification of gaps in existing literature.

Results

Four major ethical domains were identified in the literature: clinical care and delivery; education and exchange of trainees; research, monitoring and evaluation; and engagement in collaborations and partnerships. The majority of published literature related to issues of clinical care and delivery of the individual patient. Most of the published literature was published exclusively by authors in high-income countries (HICs) (80%), and the majority of articles were in the form of editorials or commentaries (69.1%). Only 12.7% of articles published were original research studies.

Conclusion

The literature on ethics in global surgery remains sparse, with most publications coming from HICs, and focusing on clinical care and short-term surgical missions. Given that LMICs are frequently the recipients of global surgical initiatives, the relative absence of literature from their perspective needs to be addressed. Furthermore, there is a need for more literature focusing on the ethics surrounding sustainable collaborations and partnerships.

Practical Bioethics for the Humanitarian Surgeon: The Development, Implementation and Assessment of an Ethics Curriculum for Residents Participating in Humanitarian Missions

BACKGROUND

Humanitarian surgeons face many ethical challenges. Despite increasing resident participation during humanitarian activities, minimal literature exists describing premission ethics training.

METHODS

A systematic literature review was conducted to identify publications on humanitarian surgery. A 3-tiered review was performed assessing for ethical conflicts and guidelines. A Humanitarian Ethics Curriculum (HEC) was developed based on these findings and administered to residents prior to a humanitarian mission. Postmission essays were assigned to describe an ethical dilemma they encountered. The HEC's value was evaluated by identifying the ACGME core competencies represented in the essays.

RESULTS

49 eligible publications were identified. Several areas of consensus were found. Controversies identified included: trainee involvement, surgical innovation, and operating on patients with dismal prognosis. All residents stated that the HEC was vital. 61% of ethical dilemmas involved surgical patients. Core competencies emphasized included systems-based practice, patient care, professionalism, interpersonal/communication skills, and medical knowledge.

CONCLUSIONS

There is consensus regarding ethical principles that surgeons should follow during humanitarian activities. However, areas of controversy persist. Premission HEC should be administered to residents participating in humanitarian missions.

Vesico-vaginal fistulae in the resource-limited setting: current status and the challenges that lie ahead, all you need to know for those practicing in a well-resourced setting

In this review we examine the incidence, aetiology, pathology and classification of vesico vaginal fistulae (VVF) in the resource poor setting. We compare the diagnosis, management and outcomes of VVF repair in resource-poor countries to current practice in the well-resourced setting, finally looking ahead to the future and the changes we need to make on a global scale in order to prevent this debilitating condition.

There is a clear need for more accurate data collection and classification systems appropriate to the setting. Lack of facilities such as radiology limit diagnostic capabilities and options for repair, however outcome data from resource poor countries is promising. Most importantly, a holistic approach, which examines not just the physical aspects of the condition but the social and cultural factors predisposing women to VVF, needs to be adopted when considering prevention and management of this injury.

Quality of life among women in Bangladesh following ileal conduit urinary diversion operations for irreparable vesicovaginal fistula and bladder exstrophy: observational study

OBJECTIVE

To determine the quality of life (QOL) of fistula patients in Bangladesh who have undergone ileal conduit (IC) urinary diversion operations, and to assess whether the risks and ethical challenges involved, outweigh the reality of leaving a woman with urinary incontinence for the rest of her life.

DESIGN

Observational study.

SETTING

LAMB Hospital, Bangladesh.

POPULATION

Seventeen women who had undergone IC between February 2012 and March 2016: 14 women previously had irreparable obstetric fistulas and three had bladder exstrophy.

METHODS

Demographic, obstetric, IC-related, stigma and discrimination information were collected by questionnaire. Univariate analysis was done using the two-sided t-test for comparison of differences before and after IC surgery.

MAIN OUTCOME METHODS

Change in stigma and discrimination scores. Health-related QOL assessed using the 36-item Short Form Health Survey.

RESULTS

Of the 17 women, 14 (82.3%) felt they were cured of their fistula disease. Three complained of occasional leakage due to insufficient seal of the bag, mainly at night, and all but one experienced no limits to their daily activities. Stigma and discrimination scores were significantly lower after having the IC surgery. The mean difference from when the woman had a fistula to when she had an IC for stigma score was 3.17 (1.12-4.16, P < 0.001), and for discrimination score was 3 (1.9-4.1, P < 0.001).

CONCLUSION

Overall, there has been improved QOL following IC among the women in this study and all would recommend IC to women in the same situation. They remain chronic patients with some physical symptoms, but are well re-integrated back into their communities.

TWEETABLE ABSTRACT

Improved QOL following ileal conduit in women with persistent fistula related disorder in Bangladesh.

Too Long to Wait: Obstetric Fistula and the Sociopolitical Dynamics of the Fourth Delay in Soroti, Uganda

Uganda has one of the highest obstetric fistula rates in the world with approximately 200,000 women currently suffering. Surgical closure successfully treats fistula in the majority of cases, yet there is a severe shortage of facilities and trained surgeons in low-resource countries. The purpose of this study was to examine Ugandan women's experiences of obstetric fistula with the aim of adding narrative depth to the clinical literature on this devastating birth injury. Data were collected through semistructured interviews, focus groups, and participant observation. Resulting narratives were consensus coded, and key themes were member-checked using reciprocal ethnography. Women who suffered from fistula described barriers in accessing essential obstetric care during labor-barriers that are consistent with the three delays framework developed by Thaddeus and Maine. In this article, we extend this scholarship to discuss a fourth, critical delay experienced by fistula survivors-the delay in the diagnosis and treatment of their birth injury.

Management of genitourinary fistula

PURPOSE OF REVIEW

To review current literature on the management of genitourinary fistulae, specifically, the techniques for diagnosis, timing to repair, surgical approach and recent advancements in surgical technique.

RECENT FINDINGS

Recent advancement in minimally invasive surgery has prompted surgeons to perform fistula repairs with laparoscopic or robotic-assisted laparoscopic techniques. Whereas there is a role for transabdominal fistula closure, the majority of fistulae are still best approached via a transvaginal route.

SUMMARY

Genitourinary fistulae from obstetric trauma have received increased attention and funding to treat and prevent this devastating condition in developing countries. Despite multiple classification systems, a standardized classification that accurately identifies predictors of successful repair is lacking. In industrialized nations, genitourinary fistulae are rare and are most frequently associated with pelvic surgery, pelvic radiation, cancer or trauma. Surgical techniques to repair these fistulae have shifted from transabdominal laparotomy to minimally invasive laparoscopic procedures. Vascularized tissue flaps can play an important role in successful closure of complex fistulae. Despite advancements in surgical technology, overarching principles of fistula closure remain. The majority of fistulae can be closed through a transvaginal approach, with a tension-free, watertight, multilayer closure.

Obstetric fistula in Burundi: a comprehensive approach to managing women with this neglected disease

BACKGROUND

In Burundi, the annual incidence of obstetric fistula is estimated to be 0.2-0.5% of all deliveries, with 1000-2000 new cases per year. Despite this relatively high incidence, national capacity for identifying and managing obstetric fistula is very limited. Thus, in July 2010, Medecins Sans Frontieres (MSF) set up a specialised Obstetric Fistula Centre in Gitega (Gitega Fistula Centre, GFC), the only permanent referral centre for obstetric fistula in Burundi. A comprehensive model of care is offered including psychosocial support, conservative and surgical management, post-operative care and follow-up. We describe this model of care, patient outcomes and the operational challenges.

METHODS

Descriptive study using routine programme data.

RESULTS

Between July 2010 and December 2011, 470 women with obstetric fistula presented for the first time at GFC, of whom 458 (98%) received treatment. Early urinary catheterization (conservative management) was successful in four out of 35 (11%) women. Of 454 (99%) women requiring surgical management, 394 (87%) were discharged with a closed fistula, of whom 301 (76%) were continent of urine and/or faeces, while 93 (24%) remained incontinent of urine and/or faeces. In 59 (13%) cases, the fistula was complex and could not be closed. Outcome status was unknown for one woman. Median duration of stay at GFC was 39 days (Interquartile range IQR, 31-51 days).

CONCLUSION

In a rural African setting, it is feasible to implement a comprehensive package of fistula care using a dedicated fistula facility, and satisfactory surgical repair outcomes can be achieved. Several operational challenges are discussed.

Ethical concerns regarding operations by volunteer surgeons on vulnerable patient groups: the case of women with obstetric fistulas

By their very nature, overseas medical missions (and even domestic medical charities such as "free clinics") are designed to serve "vulnerable populations." If these groups were capable of protecting their own interests, they would not need the help of medical volunteers: their medical needs would be met through existing government health programs or by utilizing their own resources. Medical volunteerism thus seems like an unfettered good: a charitable activity provided by well-meaning doctors and nurses who want to give of their time, skills, and resources to help those who would not otherwise be able to take care of their medical needs. In this article, I argue that if medical volunteerism is to be "good," however, it must always meet certain basic ethical requirements. These requirements may be (and perhaps often are) overlooked in the rush to organize and carry out short-term medical missions. I illustrate my point with special reference to short-term medical missions designed to provide surgical repair of obstetric vesico-vaginal fistula, a condition in which the tissues that normally separate the bladder from the vagina are destroyed by obstetric trauma, leading to continuous and unremitting incontinence in the affected woman.

Genitourinary fistula experience in Sierra Leone: review of 505 cases

PURPOSE

We reviewed cases of genitourinary fistula resulting from birth trauma in Sierra Leone to determine factors predictive of successful operative repair.

MATERIALS AND METHODS

A total of 505 operative repairs of genitourinary fistula were completed at 2 centers in Sierra Leone from 2004 to 2006. Statistical analysis of patient demographics, fistula characteristics, outcomes and surgical complications was performed.

RESULTS

Primary repairs, defined as the first repair, accounted for 68% of repairs in the population with 92% classified as vesicovaginal fistula alone. Only 56% of women were deemed to have an intact urethra at presentation and 68% were diagnosed with moderate or severe fibrosis surrounding the fistula. On univariate analysis parameters that demonstrated significant differences with primary operative success were patient age at fistula occurrence (p = 0.0192), index pregnancy (p = 0.0061), location (p <0.0001), surface area (p <0.0001), urethral status (p <0.0001) and fibrosis (p <0.0001). On multivariate analysis the fistula parameter that correlated with successful repair was the extent of fibrosis (severe fibrosis OR 3.7).

CONCLUSIONS

Genitourinary fistula as a result of prolonged obstructed labor is a cause of considerable morbidity in sub-Saharan Africa, including Sierra Leone. The most profound factor correlating with a positive operative outcome was the extent of fibrosis surrounding the fistula. These data are important to help predict the likelihood of successful repair and assist in selecting women for the appropriate surgical procedure.
