Virtual Education in Urogynecology: Enhancing Understanding and Management of Pelvic Fistulas.

Pelvic fistulas affect a significant number of patients globally, with a relatively low prevalence in the United States. Virtual education offers an effective, scalable solution to bridge this educational gap and lead to a deeper understanding of more common conditions, such as urinary and fecal incontinence. We developed two virtual cases on rectovaginal and vesicovaginal/ureterovaginal fistulas to enhance medical students' exposure, knowledge, and confidence regarding assessment of pelvic fistulas. The cases could be completed in approximately 30 minutes, asynchronously, and at students' own pace. The cases were integrated into an OB/GYN clerkship. We conducted a survey among students receiving the cases to gather feedback on usability, acceptability, and educational value, which guided subsequent improvements. Forty medical students, ranging from first to third year, participated in the urogynecology elective; 21 (53%) completed the survey. Ninety-one percent agreed or strongly agreed they were satisfied with the cases. All respondents found the format easy to use and appropriate for their level of learning. Most reported the cases improved their confidence in nonsurgical and surgical management options for pelvic fistulas. Offering virtual and interactive patient cases on e-learning platforms represents an innovative approach to increasing clinical exposure to urogynecologic disorders. By providing medical students with the opportunity to interact with pelvic fistulas virtually, these cases can help bridge a gap in clinical education. Future exploration is valuable for examining knowledge deficiencies and developing cost-effective, self-paced, easily accessible educational resources to advance medical training and optimize patient care.

Added Value of Contrast-enhanced US for Evaluation of Female Pelvic Disease.

Since the first application of contrast-enhanced US (CEUS) in the late 1960s, the use of US contrast agents has grown tremendously, and this examination has proved to be a valuable adjunct to diagnostic US for detection and characterization of disease. Also, CEUS has emerged as an excellent option for evaluation of indeterminate lesions that require additional imaging, given its excellent safety profile, including that in patients with end-stage renal disease or allergies to contrast material who are unable to undergo contrast-enhanced CT or MRI. US traditionally has been considered the imaging modality of choice for evaluation of the female pelvis, followed by MRI and rarely fluoroscopy, CT, PET, or angiography. CEUS has the potential to add significant value in imaging gynecologic disease, and indications for its use in the female pelvis are expected to continue evolving. It can aid in evaluation of nonvascular structures, such as assessment of tubal patency, uterine cavity morphology, and pelvic fistulas. CEUS can help characterize poorly vascularized gynecologic tumors or tissues with slow flow by using qualitative and quantitative parameters and aid in image-guided interventions or biopsies by facilitating visualization of lesions that are difficult to see with other imaging modalities. The authors provide an overview of current applications of US contrast agents in the female pelvis and discuss associated factors such as technique, interpretation, and image optimization. They also discuss the limitations of CEUS and describe its utility in the evaluation of female pelvic disease by using an organ system case-based approach. © RSNA, 2024 Test Your Knowledge questions for this article are available in the supplemental material.

Pelvic exenteration for late complications of radiation-induced pelvic injury: a preliminary study

Objective: To investigate the safety and efficacy of total pelvic exenteration (TPE) for treating late complications of radiation-induced pelvic injury. Methods: This was a descriptive case series study. The inclusion criteria were as follows: (1) confirmed radiation-induced pelvic injury after radiotherapy for pelvic malignancies; (2) late complications of radiation-induced pelvic injury, such as bleeding, perforation, fistula, and obstruction, involving multiple pelvic organs; (3) TPE recommended by a multidisciplinary team; (4) patient in good preoperative condition and considered fit enough to tolerate TPE; and (5) patient extremely willing to undergo the procedure and accept the associated risks. The exclusion criteria were as follows: (1) preoperative or intraoperative diagnosis of tumor recurrence or metastasis; (2) had only undergone diversion or bypass surgery after laparoscopic exploration; and (3) incomplete medical records. Clinical and follow-up data of patients who had undergone TPE for late complications of radiation-induced pelvic injury between March 2020 and September 2022 at the Sixth Affiliated Hospital of Sun Yat-sen University were analyzed. Perioperative recovery, postoperative complications, perioperative deaths, and quality of life 1 year postoperatively were recorded. Results: The study cohort comprised 14 women, nine of whom had recto-vagino-vesical fistulas, two vesicovaginal fistulas, one ileo-vesical fistula and rectal necrosis, one ileo-vesical and rectovaginal fistulas, and one rectal ulcer and bilateral ureteral stenosis. The mean duration of surgery was 592.1±167.6 minutes and the median blood loss 550 (100-6000) mL. Ten patients underwent intestinal reconstruction, and four the Hartmann procedure. Ten patients underwent urinary reconstruction using Bricker's procedure and 7 underwent pelvic floor reconstruction. The mean postoperative hospital stay was 23.6±14.9 days. Seven patients (7/14) had serious postoperative complications (Clavien-Dindo IIIa to IVb), including surgical site infections in eight, abdominopelvic abscesses in five, pulmonary infections in five, intestinal obstruction in four, and urinary leakage in two. Empty pelvis syndrome (EPS) was diagnosed in five patients, none of whom had undergone pelvic floor reconstruction. Five of the seven patients who had not undergone pelvic floor reconstruction developed EPS, compared with none of those who had undergone pelvic floor reconstruction. One patient with EPS underwent reoperation because of a pelvic abscess, pelvic hemorrhage, and intestinal obstruction. There were no perioperative deaths. During 18.9±10.1 months of follow-up, three patients died, two of renal failure, which was a preoperative comorbidity, and one of COVID-19. The remaining patients had gradual and significant relief of symptoms during follow-up. QLQ-C30 assessment of postoperative quality of life showed gradual improvement in all functional domains and general health at 1, 3, and 6 months postoperatively (all P<0.05). Conclusions: TPE is a feasible procedure for treating late complications of radiation-induced pelvic injury combined with complex pelvic fistulas. TPE is effective in alleviating symptoms and improving quality of life. However, the indications for this procedure should be strictly controlled and the surgery carried out only by experienced surgeons.

Percutaneous nephrostomy catheter-related infections in patients with gynaecological cancers: a multidisciplinary algorithmic approach

Percutaneous nephrostomy catheters (PCNs) are commonly utilized in patients with gynaecological cancers due to intrinsic or extrinsic urinary obstruction. Unfortunately, these foreign medical devices may be associated with several infectious complications, including: pyelonephritis, renal abscess, and bacteraemia, which may lead to further delay of life-saving cancer therapy. To evaluate the performance of our multidisciplinary algorithm for diagnosis and treatment of PCN-related infections (PCNIs) and identify risk factors for recurrent urinary device-related infections. Patients with gynaecological cancers having PCNIs were prospectively evaluated at our institution from July 2019 to September 2021. All patients were managed by our standardized algorithm and followed-up until reinfection or routine PCN exchange. Of 100 consecutive patients with PCNIs, 74 had adequate follow-up, and were analysed in three groups according to clinical outcome: reinfection with the same organism (26%), reinfection with a different organism (23%), and no reinfection (51%). Their median age was 54 years, and the most common cancers were cervical (65%), and ovarian (19%) with 53% being metastatic. The most frequently recovered micro-organisms were Pseudomonas (32%), Enterococcus (27%), and Escherichia (24%) species. The main risk factors for recurrent PCNI with the same organism were pelvic radiation therapy (P=0.032), pelvic fistulas (P=0.014), and a PCNI with the same pathogen within the previous year (P = 0.012). Our algorithm has allowed for accurate diagnosis, staging, and treatment of and identification of several key risk factors for recurrent PCNIs. These results may lead to further preventive measures for these infections.

Turnbull-Cutait Pull-Through Procedure Is an Alternative to Permanent Ostomy in Patients With Complex Pelvic Fistulas.

A permanent stoma is frequently recommended in the setting of complex or recurrent rectovaginal fistulas because of the high failure rate of reconstructive procedures. The Turnbull-Cutait pull-through procedure is a salvage operation for motivated patients desiring to avoid permanent fecal diversion. To analyze the cure rates of complex rectovaginal fistulas after the Turnbull-Cutait pull-through procedure based on cause. After the institutional review approval board, a retrospective review of women who underwent the procedure (1993-2018) for a rectovaginal fistula was conducted. Patients' demographics, cause, and postoperative outcomes were analyzed. Colorectal surgery department at a tertiary center in the United States. Adult women with a rectovaginal fistula who underwent a colonic pull-through procedure were included. Recurrence after the colonic pull-through procedure. There were 81 patients who underwent colonic pull-through; of those, 26 patients had a rectovaginal fistula, had a median age of 51 (43-57) years, and had a mean BMI of 28 ± 3.2 kg/m 2 . A total of 4 patients (15%) had a recurrence and 85% of the patients healed. Ninety-three percent of the patients healed after the prior anastomotic leak. Patients with a Crohn's disease-related fistula had a 75% cure rate. The Kaplan-Meier analysis showed a cumulative incidence of recurrence of 8% (95% CI, 0%-8%) within 6 months after surgery and 12% at 12 months. Retrospective design. The Turnbull-Cutait pull-through procedure may be the last option to preserve intestinal continuity and successfully treat rectovaginal fistulas in 85% of cases.

Aggressive angiomyxoma of the pelvis and abdominal wall: Dramatic response to chemical ablation therapy.

Aggressive angiomyxoma (AAM) is a rare, locally aggressive soft tissue neoplasm with a marked tendency for local recurrence after surgery. Although hormone therapy, radiation therapy, and vascular embolization can be performed, we investigated the safety and efficacy of a new chemical ablation protocol for AAM. This study included two female AAM patients from 2012 to 2016. The patients' clinical and imaging data were collected. The amount of anhydrous ethanol and glacial acetic acid used for chemical ablation was documented, and the management of any complications was detailed. The maximum dimensions of the residual tumor were 12.6cm and 14.0cm. In one case, the lesion was in the pelvis and protruded into the vulva. Eighty milliliters of liquid with a mixture of glacial acetic acid, anhydrous ethanol, and iohexol (10:9:1) was used for chemical ablation therapy via multipoint injections with a single needle. However, a pelvic fistula developed 1 month later. In another case, the lesion was located in the abdominal wall. The ablation procedure was improved by performing chemical ablation therapy with multiple needles for multi-point injections of smaller than 30ml injections for each procedure. To date, no recurrence or metastasis has been observed in the two cases. The preferred treatment for AAM is complete resection. Chemical ablation therapy is a novel adjuvant therapy for AMM. Nonetheless, more research is needed to confirm these findings.

Role of Multidetector Computed Tomography in Diagnosis of Acquired Gastrointestinal Fistulas

Abstract Introduction Fistulas are abnormal communication between two epithelialized surfaces. Gastrointestinal fistulas are communication between the gut and another epithelialized surface. Fistulas are classified according to anatomic (internal or external), physiologic (output volume), and etiologic characteristics. In the case of clinical suspicion of a fistula, a multidisciplinary approach helps in diagnosing and management. Multidetector computed tomography (MDCT) has an advantage over other imaging modalities due to its ability to reconstruct high-resolution images in seconds, which limits motion or peristalsis artifacts, and is ideal for patients who are uncooperative or who are seriously ill. Aim Evaluation of MDCT as an initial tool in the diagnosis and characterization of gastrointestinal fistulas. Methods During this prospective observational study, MDCT was used to assess patients with clinical suspicion of gastrointestinal fistulas. When necessary, contrast agents were used to identify the enteric fistulous tract. The etiology and characterization of the fistulas were determined. Further, the gastrointestinal fistulas were confirmed via endoscopy, cystoscopy, or surgery. Results The most common type of gastrointestinal fistula is enterocutaneous fistula (ECF) (39%) and the most common cause of gastrointestinal fistulas is postoperative (47%). ECFs were classified according to their etiology, anatomy, and favorable characteristics (85% favorable) along with complexity (64% complex) to aid in the management process. In addition to pancreaticopleural fistulas (22%), biliary (11%), esophageal (8%), and pelvic fistulas (19%) were also observed. There were 19% of fistulas (esophageal and biliary) that were asymptomatic. Endoscopy confirmed such asymptomatic fistulas that were not convincingly detected on CT. Conclusion In this study, we concluded that with the appropriate clinical history, MDCT can accurately depict enteric fistulas. In addition to characterizing fistulas, MDCT is equally useful for detecting secondary complications like inflammation, obstruction, or abscesses.

2030. Risk Factors for Recurrent Percutaneous Nephrostomy Tube Infections in Patients with Gynecological Malignancies

Abstract Background Percutaneous nephrostomy tube infections (PCNIs) are complex, affect quality of life, necessitate implant exchanges, and increase health care costs. Here, we analyzed risk factors for recurrent PCNIs in patients treated with our standardized institutional algorithm. Methods At our institution, we prospectively evaluated consecutive patients with gynecological malignancies who developed PCNIs between July 2019 to September 2021. All patients were treated using our institutional algorithm for PCNI, which consists of obtaining blood cultures plus urine analyses and cultures from each percutaneous nephrostomy tube (PCN); utilizing ultrasound or abdominal pelvic computed tomography scans to rule out obstructive hydronephrosis, pyelonephritis, or renal abscess; exchanging the PCN once patients are receiving concordant antimicrobial therapy; and having patients complete an adequate course of targeted antimicrobials. Thereafter, patients were followed up until reinfection, routine PCN exchange at 3 months, being lost to follow-up, or death. Results We treated 100 patients. Their median age was 54 years; 53% were White. The most common malignancies were cervical (61%), ovarian (23%), and endometrial (13%), with 60% being metastatic. To analyze the risk factors for developing a recurrent PCNI, patients were placed in 3 different groups: those reinfected with the same organism (19%), reinfected with a different organism (17%), and not reinfected (64%). Overall, there were no differences among the patient groups regarding demographics, comorbidities, clinical presentation, infection timing, PCN exchange (Table 1) or microorganisms encountered (Table 2). However, patients with prior radiation therapy or pelvic fistulas (urinary-vaginal-rectal or their permutations) had higher rates for developing a recurrent PCNIs with the same organism (P&amp;lt; .002). Conclusion Patients with prior radiation therapy and underlying pelvic fistulas have an increased risk for reinfection with the same pathogen. Therefore, further studies should be performed to mitigate this increased risk of recurrent infections with more frequent PCN exchanges or, more invasive procedure such as ureteral embolization, sclerosis, or ligation to dissociate the upper and lower urinary tracts.

Incidence of fistula occurrence in patients with cervical cancer treated with bevacizumab: data from real-world clinical practice

BackgroundThis study aimed to determine the incidence of pelvic fistulas in cervical cancer patients treated with bevacizumab in Japanese clinical practice.MethodsA post-marketing surveillance (PMS) study was conducted between June 2016 and February 2018 to survey physicians who treated advanced or recurrent cervical cancer patients with bevacizumab (according to the product label). The clinical/treatment status of patients with pelvic fistulas was assessed in an additional retrospective case series study.Results142 patients were included in the PMS study (median age 51 years; 66.9% squamous cell carcinoma; 66.2% recurrent cervical cancer; 64.1% previous radiotherapy). Patients received a median of seven bevacizumab doses. Six patients, all of whom had a history of pelvic irradiation, developed seven fistulas (4.2%; 95% confidence interval, 1.56–8.96), and five patients had also undergone pelvic surgery. The case series study of the patients who developed fistulas indicated that three patients had high cumulative bladder and rectal doses of radiation, and two of them had undergone salvage re-irradiation for pelvic recurrence. The other three patients underwent both radical hysterectomy and adjuvant radiotherapy, but did not receive an excessive radiation dose to the bladder or rectum.ConclusionsThis study found that the upper limit of the 95% confidence interval for pelvic fistula incidence did not exceed the incidence reported in the GOG 240 study. To ensure an adequate benefit-risk assessment of bevacizumab in cervical cancer patients, a comprehensive evaluation of prior treatment is essential and the possibility of unexpected fistulas, even after careful evaluation, should be considered.

Turnbull-Cutait abdominoperineal pull-through operation: The Cleveland Clinic experience in the 21st century.

The Turnbull-Cutait pull-through procedure (TCO) restores intestinal continuity in the setting of chronic pelvic sepsis, colorectal anastomotic leak, complex pelvic fistulas and technical challenges related to complicated rectal cancer. The aim of this study was to evaluate the outcomes of the TCO for salvaging complex pelvic conditions and to compare it to hand-sewn immediate coloanal anastomosis (CAA). This is a retrospective single-institution study where we searched a prospectively maintained database to identify patients who underwent the TCO. Patient demographics, operative indications and outcomes were analysed. TCO success was defined as maintenance of intestinal continuity and being stoma-free. Kaplan-Meier analysis was employed for stoma-free survival analysis. A total of 81 patients with TCO and 129 patients with CAA were included. The TCO success rate was 69% at a median of 1.4 years' follow-up with 25 (31%) patients ending up with a permanent stoma compared to 22 (17%) in the CAA group with a median follow-up of 4 years (P=0.03). The Kaplan-Meier cumulative incidence of TCO success at 1, 3 and 5 years was 79%, 60% and 51%, respectively, compared to 91%, 81% and 73% after CAA. The TCO has a high success rate for patients with complex pelvic conditions who may be facing a permanent stoma as their only option.

Rehabilitative care practices in the management of childbirth-related pelvic fistula: A systematic review.

Childbirth-related pelvic fistula (CRF) often requires surgery, yet even with successful repair, mental health conditions, musculoskeletal impairments, urinary and fecal incontinence and sexual dysfunction persist for many women. Postoperative rehabilitation, (i.e., physiotherapy, mental health counseling) may address these concerns and has been reported for this population. This review aims to summarize the literature and level of evidence of rehabilitative care practices in fistula care to inform clinical practice, research and policy recommendations. A systematic literature review was conducted using Africa-Wide Information, CINAHL, Cochrane, Embase, Global Health, PAIS Index, PubMed and SCOPUS searching keywords and MeSH terms to identify women with CRF admitted for surgery. Two researchers progressively screened titles, abstracts and full-text articles. Eligible articles were classified primary if intervention details and outcomes were reported or secondary if rehabilitation was described, but no specific outcomes reported. Relevant study details, strengths and limitations, and key findings were extracted. Eighteen articles were included: eight primary, ten secondary. Primary articles reported on urethral plugs for postoperative urinary incontinence (UI) (2/8), menstrual cup to manage UI (1/8), physiotherapy and health education (3/8) and mental health counseling (2/8). Secondary articles describe rehabilitation components in the context of program descriptions, qualitative analyses or reviews. All evidence was low or very low quality. Research on rehabilitative care is very limited and highlights inconsistencies in practice. This review provides support for the feasibility of rehabilitation and establishes the need for future interventional studies that involve a comparator and reliable outcome measures.

P268 Ileal Pouch-Anal Anastomosis Complications and Pouch Failure: A Systematic Review and Meta-Analysis

Abstract Background Previous studies demonstrated wide variation in postoperative complication rates following ileal pouch-anal anastomosis (IPAA). This systematic review aims to assess the incidence of pouch failure and the correlation between IPAA-related complications and pouch failure. Methods A systematic review was performed by searching the MEDLINE, EMBASE, and Cochrane Library databases for studies reporting on pouch failure published from 1 January 2010 to 6 May 2020. A meta-analysis was performed using a random effects model. The relationship between pouch-related complications and pouch failure was assessed using Spearman’s correlations. Results Thirty studies comprising 22,978 patients were included. Included studies contained heterogenic patient populations, different procedural stages, varying definitions for IPAA-related complications, and different follow-up periods. The pooled pouch failure rate was 7.7% (95%CI5.56–10.59) and 10.3% (95%CI7.24–14.30) for studies with a median follow-up of ≥5 years and ≥10 years, respectively. Observed IPAA-related complications were anastomotic leakage (1–17%), pelvic sepsis (2–18%), fistula (1–30%), stricture (1–34%), pouchitis (11–61%) and Crohn’s disease of the pouch (0–18%). Pelvic sepsis (r=0.51, p&amp;lt;0.05) and fistula (r=0.63, p&amp;lt;0.01) were correlated with pouch failure. A sensitivity analysis including studies with a median follow-up of ≥5 years indicated that only fistula was significantly correlated with pouch failure (r=0.77, p&amp;lt;0.01). Conclusion Long-term pouch failure was correlated with fistula, suggesting that early septic complications may result in fistula formation during long-term follow-up, leading to increased risk of pouch failure. Pouch survival may be improved through standardized assessment of anastomotic integrity for early identification and adequate management of anastomotic leaks.

EFFECTIVENESS OF RADIOLOGICAL IMAGING TECHNIQUES (X-RAYS, MDCT, AND MRI) FOR DIAGNOSIS OF PELVIC FISTULA: A SYSTEMATIC REVIEW

This study aimed to evaluate the diagnostic performance of different imaging techniques for preoperative detection of pelvic fistula. Imaging and classification of female genital abnormalities considerably pelvic floor fistulas are significant. We conducted a systematic review of the available literature to highlight the effectiveness of different radiological imaging techniques (X-RAY,U/S,CT,MRI) for the diagnosis of different types of pelvic fistulas to see the limitations of conventional scanning and testing over modern imaging techniques and to show the effectiveness of choosing one imaging modality over other depending upon multiple dynamics e.g., site and types of fistula. The controlled and regular research cases (n= 9) available in English from 2011 to 2020 were included in criteria of research. The evidence databases were used for assessment of certain studies analytically by way of PEDro scale and explicated under decision guidelines. In all relevant articles were identified and included in this systematic review. The radiological techniques showed improved diagnostic performance that established the effectiveness of imaging advancement for administration and treatment of pelvic fistula. Conventional methods have less sensitivity and specificity as compared to modern techniques. X-RAY fistulography and ultrasonography has less sensitivity and specifity as compared to CT scan but still found beneficial in the diagnosis of colovaginal, uterovesical fistula and considered as the most basic clue about the existence of a malignant fistula respectively.it is verified that MDCT is the safer accurate and offered more detailed defects in diagnosis of urogenital, urethrorectal, lower urogenital tract fistulas, upper and middle vaginal fistulas colovesical fistulas(along with X-RAY) and prostate symphyseal fistula(along with MRI).It has been concluded that MRI can access colovesical fistulas inherited vaginal fistulas and prostate symphyseal fistulas(along with CT) more efficiently. It has been concluded that diagnostic imaging for all pelvic fistula is useful, to help the physicians, particularly radiologists, in diagnosis of pelvic fistulas. The choice of imaging technique is dependent upon multiple factors. Advanced medical imaging techniques XRAY,MDCT MRI) are considered more recommended choices as compared to conventional imaging.

Case Study: Infected Disrupted Perineal Wound Treatment with Negative Pressure Wound Therapy (NPWT) and Wound Reconstruction Using Gracilis Muscle Flap Following the Abdominoperineal Excision (APE) in Patient with Rectum Injury Due to Motorcycle Accident

Blunt trauma sustained in traffic accidents can cause significant rectum injury, either intra or extraperitoneal. Severe injuries have high mortality rates and many complications, including pelvic absesses, sepsis, rectal fistulas, stenosis, and rectal incontinence. Following the initial surgical procedure, many reconstructive methods can be used to treat perineal wounds, including gracilis myocutaneus flap, rectus abdominis flap, gluteal flap, perforator flap, posterior thigh flap, groin flap, and pudendal fasciocutaneous flap. NPWT is used to promote formation of granulation tissue, reduce and prepare tissue gap to be covered, improve perfusion through removal of excessive fluid, and reduce bacterial wound colonization. Some of the complications of this method are pain, skin irritation and maceration, tissue necrosis, bleeding, and infection. The success rate of NPWT depends on multiple factors, including patient characteristics, effectiveness of primary surgical procedure and need for further surgical interventions, size and depth of the wound, and proper NPWT application technique. NPWT has shown to reduce total treatment cost due to shorter patient hospital stay, reduction of complication rates, reduction of further surgical interventions, and lower frequency of dressing change compared with standard dressings. In this case study, I present a 53-year-old motorcyclist who was injured in a traffic accident and sustained fracture of the sacrum, rupture of the pubic symphysis, fracture of L5 vertebrae, and penetrant injury to the rectum. Multiple explorative laparotomies, colostomy, and supportive and drug treatment methods were carried out to obtain a successful outcome.

Ultrasound in the Diagnosis of Malignant Pelvic Fistulas: Sonographic Findings in Correlation with Computed Tomography Imaging

Even though ultrasound is an extensively used imaging modality, it has not been effectively utilized in the evaluation and diagnosis of malignant pelvic fistulas. In this study, we tried to correlate the accuracy of sonographic findings in identifying malignant fistulas with that of computed tomography (CT) imaging. Thirty-five patients with advanced pelvic malignancies were examined over a period of 2 y. Patients underwent CT of the abdomen and pelvis with intravenous and oral/rectal contrast followed by ultrasound of the abdomen. Sonographic examinations were performed using a standardized protocol with a full bladder. Real-time ultrasound images of the abdomen and pelvis in multiple planes were acquired and stored as both image files and audio-video interleaves (AVIs). On ultrasound, the majority of the fistulas were visualized either as a continuous hyper-echoic tract within a hypo-echoic neoplastic mass (“air contrast sign”) or as multiple discontinuous hyper-echoic foci with “ring down” artifacts. The sensitivity and specificity of ultrasound in the detection of malignant fistulas were 72% (confidence interval [CI]: 52%–87%) and 66% (CI: 22%–95%), respectively. We also reviewed the literature and compared the sensitivities of ultrasound in the detection of various types of pelvic fistulas obtained in previous studies with those in the present study. Results suggest that although ultrasound cannot be used as a primary imaging modality for the detection of fistulas, it can provide the earliest clue to the presence of a malignant fistula.

Evaluation of genitourinary fistulas in pelvic malignancies with etiopathologic correlation: role of cross sectional imaging in detection and management.

Genitourinary fistulas in pelvic malignancies are abnormal communications occurring due to either locally advanced tumours invading the surrounding organs or post-therapeutic complications of malignancies. In this article we review and describe the role of cross-sectional imaging findings in the management of genitourinary fistulas in pelvic malignancies. A retrospective study, for the period January 2012 to December 2018, was undertaken in patients with pelvic malignancies having genitourinary fistulas. The cross-sectional (CT and MRI) imaging findings in various types of fistulas were reviewed and correlated with the primary malignancy and the underlying etiopathology. Genitourinary fistulas were observed in 71 patients (6 males, 65 females). 11 types of fistulas were identified in carcinomas of cervix, rectum, ovary, urinary bladder, sigmoid colon, vault, endometrium and prostate. The commonest were rectovaginal and vesicovaginal fistulas. 13 patients had multiple fistulas. The sensitivity, specificity, positive and negative predictive values of CT and MRI are 98%, 100%, 66%, 98% and 95%, 25%, 88% and 50% respectively. Contrast-enhanced CT with oral and rectal contrast is more sensitive and specific than MRI in the evaluation of genitourinary fistulas. Imaging findings significantly influence the management and outcome of genitourinary fistulas in pelvic malignancies. Contrast-enhanced CT is the imaging modality of choice in the evaluation of pelvic fistulas associated with malignancies and MRI is complimentary to it. To our knowledge, this study is the first of its kind wherein the mean duration of occurrence of fistulas in pelvic malignancies is correlated with the underlying etiopathology.

Martius labial fat pad graft (use in rectovaginal fistula repair).

The objective is to demonstrate the utility of the Martius labial fat pad graft in pelvic fistula repair. An incision is made over the labium majus from the level of the clitoral hood superiorly and extending inferiorly to the level of the labiocrural fold. The fibrofatty graft is then mobilized from the adjacent labium majus. The flap can be divided either at its anterior or at its posterior pedicle. A subepithelial defect is created through which the flap will be passed. The flap is sewn into place by attaching it to the underlying rectovaginal fascia without associated tensioning. Next, the posterior vaginal wall is closed over the graft with a series of everting subepithelial mattress sutures followed by a reinforcing layer of interrupted #1 Vicryl through the vaginal epithelium. The advantages of the Martius flap in fistula repair include low morbidity, lack of a cosmetic defect, and the need for only a single surgical field. Its prominent fibrous component makes it a stronger graft than adipose tissue from other areas and its abundant blood supply promotes rapid neovascularization and lends itself well to many surgical modifications that can be utilized in even the most difficult of fistula repairs.

Martius Labial Fat Pad Graft (use in RVF Repair)

Video Objective To demonstrate the utility of the Martius Labial Fat Pad Graft in pelvic fistula repair. Setting We present a minimally invasive surgical approach for a patient with recurrent rectovaginal fistula. Interventions An incision is made over the labium majus exposing the yellow fibrofatty graft. This graft is first retracted medially where a natural tissue plane facilitates dissection from the adjacent labium majus. It is then retracted laterally where a plane between it and the bulbocavernosus muscle is developed. To avoid devascularization of adjacent skin, a thin fatty layer is left attached at its undersurface. The division of the flap is begun in this case, at its anterior pedicle. It is important to develop a flap that easily covers the defect with a good degree of overlap. Once the flap has been sufficiently mobilized, a shellcross is used to create the subepithelial defect to enable passage of the flap through the levator plate. This defect is widened enough to prevent compression on the pedicled blood supply. After appropriate positioning, the flap is sewn into place by attaching it to the adjacent, underlying rectovaginal fascia with interrupted 2-0 Vicryl suture. It is important to note that no tensioning of the flap is required to approximate it to the adjacent tissue. The posterior vaginal wall is next closed over the graft in two layers followed by closure of the labial defect. Conclusion The Martius flap has multiple minimally invasive advantages in fistula repair to include low morbidity, lack of a cosmetic defect and the need for only a single surgical field. Its’ abundant blood supply promotes rapid neovascularization of the transplanted graft and lends itself well to a variety of surgical modifications that can be utilized in the repair of even the most difficult of fistulas.

Bangladesh Fistula Mission Partnership: Leveraging Assets from the United States Agency for International Development and the Department of Defense to Address a Health Care Crisis in a Developing Nation.

Obstetric fistulae are a leading scourge for women in developing countries resulting, in severe individual suffering and devastating socio-economic repercussions for her family and community. The underlying causes of obstetric fistula stem from multiple factors to include poor nutrition, early marriage, insufficient education and inferior social status of women as well as substandard medical care. The US Agency for International Development (USAID) has invested more than $100 million globally since 2004 to address these factors as well as support women suffering with fistulae. The ultimate goal is to eradicate obstetric fistula in Bangladesh in the next 20 years. Despite these efforts, nearly 20,000 women in Bangladesh, still suffer with this malady. To close this gap, USAID and the Department of Defense (DOD) developed a novel Interagency Agreement (IAA) leveraging the surgical skills of military health professionals to scale-up the ongoing fistula care program. The agreement outlined three lines of effort: (1) treat existing fistulae by bolstering surgical capacity of the existing USAID fistula care program; (2) promote fistula mitigation with lectures and hands-on teaching of obstetric care as well as safe gynecologic surgery; and (3) assist with advocacy at higher levels of the Bangladesh government. A Bangladesh Fistula Mission Partnership working group was formed to design and implement this IAA. Critical partners from the US Embassy in Dhaka included USAID (Health, Legal, Contracting), the DOD (Office of Defense Cooperation), and Department of State (Regional Security Officer). Partners from the US Army included United States Army-Pacific Command (Surgeon, Legal, Finance, Security Cooperation, Contracting), Regional Health Command-Pacific (Operations, Legal, Public Affairs), and Tripler Army Medical Center (Department of OBGYN, Operations, Public Affairs). Institutional Review Board approval was not required as the treatments offered were standard of care. The Tripler Army Medical Center (TAMC) health professionals executed the IAA with one pre-deployment site survey and two surgical missions in 2016-2017. The military team supported the surgical repair of 40 pelvic fistulae and perineal tears and provided operative management for an additional 25 patients with pelvic organ prolapse. Furthermore, the team conducted 19 professional lectures and multiple educational forums at hospitals in Kumudini, Khulna and the premier medical university in Dhaka for over 800 attendees including physicians, nurses and students to help prevent obstetric and surgical fistulae. Importantly, the team assisted USAID as subject matter experts in its advocacy to the Bangladesh Ministry of Health for improved maternity care and regulatory oversight. During the missions, the team enhanced their readiness by exercising individual and collective tasks while exposing personnel to the cultural context of the region. This IAA was the first USAID funded and DoD-executed health mission in the US Indo-Pacific Command Area of Responsibility. Direct participation in the IAA enabled TAMC to support the US Indo-Pacific Command Theater Campaign Plan, the Department of Defense Instruction 2000.30 on Global Health Engagements, the USAID Country Development Cooperation Strategy, and the US Ambassadors Integrated Country Strategy Objectives in Bangladesh. This effort can serve as a model for future cooperation between USAID and the DoD.
