RESUMEN
BACKGROUND: Rectovaginal fistula (RVF) is an abnormal channel formed by epithelial tissue between the anterior wall of the rectum and the posterior wall of the vagina, which manifests as vaginal gassing and defecation. It is one of the common complications of female pelvic surgeries. With the increased number of proctectomies for rectal cancer, the number of postoperative rectovaginal fistulas also increases. Once RVF occurs, the failure rate is still high with various treatments available. RVF causes great suffering to women and is still a major problem in treatment. Therefore, it is significant for female rectal cancer patients to prevent RVF after rectal cancer surgery. In this study, we introduce a new method to prevent RVF during rectal cancer radical operation. METHODS: In this randomized controlled trial (RCT), all operations are performed according to the principle of total mesorectal excision (TME) radical resection in rectal cancer surgery. All eligible participants will be divided into two groups: the experimental group and the control group. Experimental group: the anterior rectal wall of about 1 cm distal to the anastomosis was dislocated. Before the anastomosis of the rectal end, a fat flap (usually left side) containing the ovarian vascular pedicle was dislocated, measured by 10-15 cm in length and 2 cm in width. The fat flap containing the ovarian vascular pedicle was packed and fixed anterior to the anastomotic stoma with fibrin glue. CONTROL GROUP: surgery will be carried out in accordance with the TME principle. Participants will be compared on several variables, including the incidence of RVF after operation (primary outcomes), the occurrence time of postoperative RVF, the occurrence time of RVF after stoma closure, and other postoperative complications, such as anastomotic leakage, chylous leakage, and intestinal obstruction (secondary outcomes). The follow-up data collection will be conducted according to the follow-up time point, and the baseline data will also be collected for follow-up analysis. By comparing the incidence of rectovaginal leakage between the experimental group and the control group, we aim to explore the feasibility of this method for the prevention of postoperative RVF. DISCUSSION: This RCT will explore the feasibility of packing with a laparoscopic dislocated fat flap containing an ovarian vascular pedicle anterior to the anastomotic stoma after rectal cancer surgery to prevent RVF.

STUDY OBJECTIVE: To assess whether a liberal policy of preventive stoma (LPS) reduces the rate of rectovaginal fistulas in women with excision of deep endometriosis requiring concomitant vaginal and rectal sutures in comparison with a more restrictive policy of preventive stoma (RPS) and to assess the risk factors for rectovaginal fistula. DESIGN: Retrospective before-and-after comparative study. SETTING: Two referral centers, one with an LPS and the other with an RPS. PATIENTS: A total of 363 patients with deep endometriosis infiltrating the rectum and the vagina. INTERVENTIONS: Rectal disc excision or colorectal resection concomitantly with vaginal excision. MEASUREMENTS AND MAIN RESULTS: Two hundred forty-one and 122 women received surgery at the LPS and RPS centers, respectively. The rate of preventive stomas was 71.4% at the LPS center (n = 172) and 30.3% at the RPS center (N = 37). Rectovaginal fistula was recorded in 31 cases (8.5%): nineteen women were managed at the LPS center, and 12 women underwent surgery at the RPS center. It occurred in, respectively, 9.4%, 10.8%, 10.1%, and 7% of the women managed without and with a stoma at the RPS center and of those managed without and with a stoma at the LPS center (p = .72). The height of the rectal stapled line was significantly lower in the women undergoing a stoma, particularly in those managed at the RPS center (5.4 ± 1.8 cm). Performing rectal sutures within 8 cm from the anal verge increased the risk of rectovaginal fistula more than 3-fold, independently of stoma creation, surgical procedure carried out on the rectum, size of vaginal infiltration, or associated excision of deep endometriosis involving the pelvic nerves (odds ratio 3.4; 95% confidence interval, 1.3-9.1). CONCLUSION: No statistically significant differences were found in terms of the risk of rectovaginal fistula between women with rectovaginal endometriosis managed by either an LPS or an RPS; however, these findings need to be confirmed by a randomized trial.

OBJECTIVE: To evaluate the risk of rectovaginal fistula after en bloc hysterectomy and colorectal resection (H-CR) for endometriosis using prevesical peritoneum interposition. STUDY DESIGN: A retrospective study conducted at Tenon University Hospital, expert center in endometriosis, from June 2016 to June 2018. Patients undergoing H-CR with prevesical peritoneum interposition without protective defunctioning stoma were included. RESULTS: Of the 160 patients who underwent surgery with colorectal resection for endometriosis during the study period, 27 had H-CR (15 with segmental and 12 with discoïd colorectal resection) and were included. The median age (range) was 45 years (41-47.5). Eight patients (13 %) were nulliparous. All procedures were performed by laparoscopy. Parametrial resection was performed in 14 cases (52 %). Associated bowel procedures were ileocecal resection (n = 5) and appendectomy (n = 2). Median follow-up (range) was 14.6 months (10.5-20.2). Nine (33.3 %) patients experienced intra- or postoperative complications including one grade I, four grade II, two grade IIIA and two grade IIIB complications (Clavien-Dindo classification). Seven patients (26 %) experienced postoperative voiding dysfunction. One suspicion of rectovaginal fistula associated with pelvic abscess was diagnosed 4 weeks after surgery but not confirmed during a second operation. CONCLUSION: Despite the small sample size, the present pilot study supports the practice of prevesical peritoneum interposition to limit the risk of rectovaginal fistula in patients who undergo H-CR for deep endometriosis.

INTRODUCTION AND HYPOTHESIS: Endometriosis is a gynecological condition characterized by endometrial tissue outside of the uterus. It affects up to 15% of women of reproductive age. In the case of bowel infiltration, about 90% of lesions are localized on the sigmoid colon or the rectum and may interfere with bowel function. Three surgical approaches are possible: (1) shaving technique, (2) discoid resection of the nodule, and (3) segmental resection with end-to-end anastomosis. A rectovaginal fistula is feared as a postoperative complication mainly in simultaneous resection of the vaginal and the rectosigmoid nodules. Its prevention is a two-step surgery (the first operation on the vagina and the second on the colon) or a preventive colostomy, both of which are often thought to be too invasive for a benign condition. Herein, we suggest a one-step surgery to prevent its development. METHODS: In three women, a concomitant laparoscopic resection of the vaginal and rectosigmoid endometrial nodule was completed with interposition of a mesorectal flap. RESULTS: All surgeries were uncomplicated with no rectovaginal fistula in the postoperative period. CONCLUSION: In the hands of skilled surgeons, this one-step technique can be used to prevent rectovaginal fistula development.

Although obstetric fistula has likely plagued women since the beginning of time, very little research proportionally exists. This article summarizes the most substantial research on the topic and delineates research gaps and future needs. Existing research demonstrates that access to care is the underlying cause of obstetric fistula and that the first attempt at closure holds the highest chance at success, ranging between 84% and 94%. For simple cases, 10 days of a catheter is sufficient, although what constitutes as simple is unclear. Circumferential fistulas are at high risk for ongoing urethral continence. Psychosocial programs are helpful for all women, but those who are "dry" tend to reintegrate into society, whereas those still leaking need additional support. Prenatal care and scheduled cesarean delivery are recommended to avoid another fistula. Gaps in research include accurate prevalence and incidence, interventions to improve access to care, surgical technique, especially for complex cases, and ways to prevent ongoing incontinence, among many others. In all areas, more rigorous research is needed.

OBJECTIVE: To assess the effect of early pregnancy on obstetric fistula. METHODS: A prospective observational study was conducted among patients with obstetric fistula caused by a long obstructed labor who presented at Selian Lutheran Hospital, Tanzania, or Kitovu Hospital, Uganda, between January 1, 2015, and January 31, 2016. Demographic and clinical variables were evaluated. RESULTS: Among 270 patients, 162 (60.0%) experienced their first pregnancy up to 2 years after menarche (early group) and 108 (40.0%) experienced their first pregnancy more than 2 years after menarche (late group). No significant differences between the early and late groups were found for median age at presentation (30.0 vs 28.0 years), median parity (both 2.0), stillbirth (n=145 [89.5%] vs n=95 [88.0%]), median duration of labor (both 2.0 days), home delivery (n=31 [19.1%] vs n=17 [15.7%]), cesarean delivery (n=79 [48.8%] vs 58 [53.7%]), median time from obstetric fistula formation to presentation (48.0 vs 24.0 months), and obstetric fistula classifications. Obstetric fistula occurred during the first pregnancy in 99 (61.1%) women in the early group and 71 (65.7%) in the late group (P=0.440). CONCLUSION: Frequency of obstetric fistula during the first pregnancy is not increased among women who experience their first pregnancy within 2 years of menarche.

BACKGROUND: Obstetric Fistula is a childbirth injury that disproportionately affects women in sub-Saharan Africa. Although poverty plays an important role in perpetuating obstetric fistula, sociocultural practices has a significant influence on susceptibility to the condition. AIM: This paper aims to explore narratives in the literature on obstetric fistula in the context of Hausa ethno-lingual community of Northern Nigeria and the potential role of nurses and midwives in addressing obstetric fistula. DISCUSSION: Three major cultural practices predispose Hausa women to obstetric fistula: early marriages and early child bearing; unskilled birth attendance and female circumcision and sociocultural constraints to healthcare access for women during childbirth. There is a failure to implement the International rights of the girl child in Nigeria which makes early child marriage persist. The Hausa tradition constrains the decision making power of women for seeking health care during childbirth. In addition, there is a shortage of nurses and midwives to provide healthcare service to women during childbirth. CONCLUSION: To improve health access for women, there is a need to increase political commitment and budget for health human resource distribution to underserved areas in the Hausa community. There is also a need to advance power and voice of women to resist oppressive traditions and to provide them with empowerment opportunities to improve their social status. The practice of traditional birth attendants can be regulated and the primary health care services strengthened.

BACKGROUND: Increasing births with skilled attendants and increasing health facilities with Emergency Obstetric Care (EmOC) can reduce maternal mortality and are considered critical interventions for ensuring safe motherhood. Despite Tanzania's policy to support women to give birth with the assistance of skilled personnel, some women do not access this care. This article uses women's stories to illustrate the challenges that caused them to fail to access adequate obstetric care in a timely manner, hence causing the development of fistulas. METHODS: This paper presents the narratives of 16 women who were conveniently selected based on their experiences of not being able to access adequate obstetric care in timely manner. The analysis was guided by recommendations for the identification and interpretation of narratives, and identified important components of women's experiences, paying attention to commonalities, differences and areas of emphasis. Semi-structured interviews were carried out at CCBRT hospital in Dar es Salaam. RESULTS: Four (4) general story lines were identified from women description of their inability to access quality obstetric care in a timely manner. These were; failing to decide on a health care facility for delivery, lacking money to get to a health care facility, lacking transportation to a health care facility and lacking quality birth care at the health care facility. CONCLUSION: Women were unable to reach to the health care facilities providing comprehensive emergency obstetric care (CEmOC) in time because of their lack of decision-making power, money and transportation, and those who did reach the facilities received low quality birth care. Empowering women socially and financially, upgrading primary health care facilities to provide CEmOC and increased numbers of skilled personnel would promote health care facility deliveries.

BACKGROUND: Obstetric fistula is a worldwide problem that is devastating for women in developing countries. The cardinal cause of obstetric fistula is prolonged obstructed labour and delay in seeking emergency obstetric care. Awareness about obstetric fistula is still low in developing countries. The objective was to assess the awareness about risk factors of obstetric fistulae in rural communities of Nabitovu village, Iganga district, Eastern Uganda. METHODS: A qualitative study using focus group discussion for males and females aged 18-49 years, to explore and gain deeper understanding of their awareness of existence, causes, clinical presentation and preventive measures for obstetric fistula. Data was analyzed by thematic analysis. RESULTS: The majority of the women and a few men were aware about obstetric fistula, though many had misconceptions regarding its causes, clinical presentation and prevention. Some wrongly attributed fistula to misuse of family planning, having sex during the menstruation period, curses by relatives, sexually transmitted infections, rape and gender-based violence. However, others attributed the fistula to delays to access medical care, induced abortions, conception at an early age, utilization of traditional birth attendants at delivery, and some complications that could occur during surgical operations for difficult deliveries. CONCLUSION: Most of the community members interviewed were aware of the risk factors of obstetric fistula. Some respondents, predominantly men, had misconceptions/myths about risk factors of obstetric fistula as being caused by having sex during menstrual periods, poor usage of family planning, being a curse.

UNLABELLED: An obstetric fistula is classically regarded as an "accident of childbirth" in which prolonged obstructed labor leads to destruction of the vesicovaginal/rectovaginal septum with consequent loss of urinary and/or fecal control. Obstetric fistula is highly stigmatizing and afflicted women often become social outcasts. Although obstetric fistula has been eliminated from advanced industrialized nations, it remains a major public health problem in the world's poorest countries. Several million cases of obstetric fistula are currently thought to exist in sub-Saharan Africa and south Asia. Although techniques for the surgical repair of such injuries are well known, it is less clear which strategies effectively prevent fistulas, largely because of the complex interactions among medical, social, economic, and environmental factors present in those countries where fistulas are prevalent. This article uses the Haddon matrix, a standard tool for injury analysis, to examine the factors influencing obstetric fistula formation in low-resource countries. Construction of a Haddon matrix provides a "wide angle" overview of this tragic clinical problem. The resulting analysis suggests that the most effective short-term strategies for obstetric fistula prevention will involve enhanced surveillance of labor, improved access to emergency obstetric services (particularly cesarean delivery), competent medical care for women both during and after obstructed labor, and the development of specialist fistula centers to treat injured women where fistula prevalence is high. The long-term strategies to eradicate obstetric fistula must include universal access to emergency obstetric care, improved access to family planning services, increased education for girls and women, community economic development, and enhanced gender equity. Successful eradication of the obstetric fistula will require the mobilization of sufficient political will at both the international and individual country levels to ensure that adequate resources are devoted to this problem and that maternal health becomes a high priority on national political agendas. TARGET AUDIENCE: Obstetricians & Gynecologists and Family Physicians. LEARNING OBJECTIVES: After participating in this CME activity, physicians should be better able to apply the Haddon matrix, a tool commonly used for injury analysis, to the field of obstetrics and gynecology; analyze the problem of obstructed labor and obstetric fistula formation in low-resource countries using the Haddon matrix, and implement possible strategies for the prevention of obstetric fistulas and the mitigation of harm in cases of obstructed labor that arise from the use of the Haddon matrix.

OBJECTIVE: The objective of the study is to assess the efficacy of vital bulbocavernosus graft transposition in the treatment of rectovaginal fistula. MATERIALS AND METHODS: From March 2003 to October 2007, nine consecutive patients diagnosed with rectovaginal fistula were refereed to our institute. All patients were treated using an interposing vital bulbocavernosus graft between rectum and vagina. RESULTS: Median patient age was 33 years (range, 19-61) and seven of the nine patients had undergone between one and six fistula repair sessions prior to this grafting procedure. The etiology included congenital in three, surgery injury in four, obstetric in one, and radiation in one. No wound infections or abscesses occurred postoperatively, and the in-hospital mortality rate was zero. No recurrence was reported during the follow-up period and all patients had normal fecal continence. Only one patient had mild dyspareunia and no further surgical treatment needed. CONCLUSION: Both simple and complex rectovaginal fistula can be reliably repaired using a bulbocavernosus graft.

BACKGROUND & AIMS: The ACCENT II study (A Crohn's Disease Clinical Trial Evaluating Infiximab in a New Long-term Treatment Regimen in Patients With Fistulizing Crohn's Disease) evaluated the efficacy and safety of infliximab maintenance treatment in patients with fistulizing Crohn's disease. This post hoc analysis was conducted to determine the efficacy and safety of infliximab therapy in women with rectovaginal fistulas. METHODS: All patients received 5 mg/kg infliximab intravenously at weeks 0, 2, and 6. Patients who achieved response at weeks 10 and 14 then were randomized as responders if they had at least 50% of baseline fistulas closed, or as nonresponders, to receive placebo or infliximab 5 mg/kg every 8 weeks through week 54. RESULTS: Of 282 patients in the ACCENT II study, 25 of 138 (18.1%) women had a total of 27 draining rectovaginal fistulas at baseline. After infusions of infliximab at weeks 0, 2, and 6, 60.7% (17 of 28) and 44.8% (13 of 29) of rectovaginal fistulas were closed at weeks 10 and 14, respectively. Among responders, 72.2% (13 of 18) of rectovaginal fistulas were no longer draining at week 14. The duration of rectovaginal fistula closure was longer in the infliximab 5-mg/kg maintenance group (median, 46 wk) than in the placebo group (33 wk). CONCLUSIONS: Infliximab is effective in short-term closure of rectovaginal fistulas and maintenance treatment was more effective than placebo in prolonging rectovaginal fistula closure.

Postpartum fistulas are frequent in the tropical environment. They are mostly found in very young women who live in remote areas. Without treatment women with fistulas will be condemned to the disconsolate life of social outcasts. Good operative treatment is crucial. The different operative methods are discussed. The operation through vaginal approach can be performed in any hospital. It does not need special surgical skill. More important than surgery is prevention of postpartum fistulas through a well-organised primary health care program which reaches out into the villages and which includes adequate prenatal controls and competent midwifery.
PIP: In tropical environments, fistulas between the vagina and the bladder or rectum are common in postpartum women. This condition is most frequent in very young women from remote rural areas whose deliveries are attended by midwives untrained in the management of obstructed labor. As a result of the continuous seepage of urine and/or feces associated with this condition, women with fistulas face social ostracism. Thus, the prevention and adequate treatment of postpartum fistulas are important tasks for health services in the tropics. Unlike complicated transperitoneal procedures, a vaginal approach to fistula treatment does not require special surgical skills and can be performed under spinal anesthesia. 75-85% of first surgeries for postpartum fistula are successful (defined as no leakage of urine or feces and resumption of normal sexual relations). The success rate depends, however, on factors such as the exact localization and extension of the fistula, involvement of the urethra, the closing mechanism of the bladder, and the experience of the surgeon. Prevention of postpartum fistula requires good prenatal care, including the referral of primiparas with small or abnormal pelvic proportions to a hospital for delivery, and adequate maternity facilities, especially the availability of midwifery staff trained in vacuum extractor use and symphysiotomy performance.
