Genitourinary Fistula: epidemiology, changing trends in etiology and management: A tertiary care institute's perspective.

INTRODUCTION: Urogenital fistula is a physically, socially and psychologically devastating condition for the patient. In developed countries, these fistulae are typically related to gynecological surgery, pelvic pathology like malignancy or post radiation therapy. In contrast, classical teaching is that urogenital fistulae in the developing countries like India are usually associated with prolonged labor and obstetric complications. This retrospective study conducted at a tertiary care health Institute shows a paradigm shift in epidemiology, etiology and management of genitourinary fistulae in India in recent times. METHODS: This retrospective study included patients undergoing surgical repair for various genitourinary fistulae at our institute from 2016 to 2022. Epidemiology, etiology, site, size and number of fistulae, clinical presentation, and management records of these patients were recorded and reviewed retrospectively. RESULTS: In our study, the mean age of the patients was 38.4 ± 10.2 years. Vesicovaginal Fistula (VVF) was found to be most common fistula in the study population (87.5%) followed by vesicouterine (7.1%) and urethrovaginal fistula (5.4%). The causes of genitourinary fistula were iatrogenic (73.2%), carcinoma of cervix (16.1%), obstructed prolonged labor (7.1%), and genitourinary tuberculosis (3.57%). Among the 48 vesicovaginal fistulas that underwent surgery, 45.8% were treated using a transvaginal approach, 29.2% were managed through a laparoscopic transabdominal repair, and 25% were addressed using a robotic approach. Recurrence occurred in 7.1% of the operated patients. CONCLUSION: Enhanced healthcare services in the country have contributed to a decrease in the incidence of obstructed labor, subsequently reducing related injuries. Iatrogenic injuries resulting from gynecological surgeries and carcinoma cervix have given rise to more complex fistulas, necessitating the implementation of advanced treatment strategies.

Diagnosis and treatment of primary ileal pouch leaks: a 27-year experience at a referral center.

BACKGROUND: Ileal pouch-anal anastomosis (IPAA) is considered the preferred restorative surgical procedure for patients with ulcerative colitis and familial adenomatous polyposis requiring proctocolectomy. Unfortunately, postoperative leaks remain a complication with potentially significant ramifications. This study aimed to provide a comprehensive description of the evaluation, management, and outcomes of leaks after primary IPAA procedures. METHODS: Between 1995 and 2022, a total of 4058 primary IPAA procedures were performed at Cleveland Clinic. From a prospectively maintained pouch registry, we retrospectively reviewed the data of 237 patients who presented to the pouch center for management. Of these, 114 (3%) had undergone the index IPAA procedure at our clinic (de novo cases), whereas 123 patients had their index IPAA performed elsewhere. Data were missing for 43 patients, resulting in a final cohort of 194 patients. RESULTS: Our cohort had an average age of 41 years (range, 16-76) at the time of leak diagnosis. Overall, 55.2% were males, average body mass index was 24.4 kg/m2, and pain was the most prevalent presenting symptom (61.8%), followed by fever (34%). Leaks were confirmed through diagnostic testing in 141 cases, whereas 27.3% were detected intraoperatively. The most common initial diagnoses were pelvic abscess (47.4%) and enteric fistulas (26.8%), including cutaneous (9.8%), vaginal (7.2%), and bladder fistulas (3.1%). By location, leaks occurred at the tip of the "J" (52.6%), at the pouch-anal anastomotic site (35%), and in the body of the pouch (12.4%). A nonoperative management approach was initially attempted in 49.5% of cases, including antibiotic therapy, drainage, endoclip, and endo-sponge, with a success rate of 18.5%. Surgery was eventually required in 81.4% of patients, including (1) sutured or stapled pouch repair (52.5%), with diversion performed in 87.9% of these cases either before or during the salvage surgery; (2) pouch excision with neo-IPAA (22.7%), including 9 patients from the first group; and (3) pouch disconnection, repair, and reanastomosis (9.3%). Pouch failure occurred in 8.4%, with either pouch excision (11.1%) or permanent diversion (4.5%). Ultimately, 12.4% of patients (24 of 194) required permanent diversion, with all necessitating pouch excision. In the 30-day follow-up after salvage surgery, short-term complications arose in 38.7% of patients. The most common complications observed were ileus, pelvic abscess/sepsis, and fever. CONCLUSION: Leaks after primary IPAA procedures represent an infrequent, yet challenging, complication. Despite attempts at nonoperative management, the success rate is limited. Salvage surgery is associated with a high pouch retention rate, underscoring its importance in the management of post-IPAA leaks.

Gracilis muscle interposition for pouch-vaginal fistulas: a single-centre cohort study and literature review.

BACKGROUND: First described by Parks and Nicholls in 1978, the ileal pouch-anal anastomosis (IPAA) has revolutionized the treatment of mucosal ulcerative colitis (MUC) and familial adenomatous polyposis (FAP). IPAA is fraught with complications, one of which is pouch-vaginal fistulas (PVF), a rare but challenging complication noted in 3.9-15% of female patients. Surgical treatment success approximates 50%. Gracilis muscle interposition (GMI) is a promising technique that has shown good results with other types of perineal fistulas. We present the results from our institution and a comprehensive literature review. METHODS: A retrospective observational study including all patients with a PVF treated with GMI at our institution from December 2018-January 2000. Primary outcome was complete healing after ileostomy closure. RESULTS: Nine patients were included. Eight of nine IPAAs (88.9%) were performed for MUC, and one for FAP. A subsequent diagnosis of Crohn's disease was made in five patients. Initial success occurred in two patients (22.2%), one patient was lost to follow-up and seven patients, after further procedures, ultimately achieved healing (77.8%). Four of five patients with Crohn's achieved complete healing (80%). CONCLUSION: Surgical healing rates quoted in the literature for PVFs are approximately 50%. The initial healing rate was 22.2% and increased to 77.8% after subsequent surgeries, while it was 80% in patients with Crohn's disease. Given this, gracilis muscle interposition may have a role in the treatment of pouch-vaginal fistulas.

The reintegration of obstetric fistula survivors in Malawi: Perspectives of healthcare providers.

OBJECTIVE: In Malawi, women face a high risk of obstetric fistulas. There are many socio-cultural implications for women suffering from the condition, many of which continue to affect them even after they have undergone treatment and attempt to reintegrate into their lives. The focus of this study was to explore the socio-cultural factors that influence the reintegration of obstetric fistula survivors in Malawi from the perspectives of healthcare providers. DESIGN: This qualitative study was conducted at a hospital in Central Malawi, which houses a non-governmental organization (NGO) that is wholly dedicated to the treatment and reintegration of obstetric fistula patients and survivors. In total, in-depth interviews was conducted with 15 healthcare providers. FINDINGS: After surgery, survivors are given economic and social empowerment assistance to allow them to gain independence from their families. Counselling interventions help patients overcome their isolation and depression so they may begin to interact with others. In some circumstances, the initial surgeries may be unsuccessful, causing anxiety and doubt among the women. Some survivors no longer desired to bear children in the future, which negatively impacted their marriages and social status. KEY CONCLUSION: It is imperative to overcome the socio-cultural beliefs that impact the treatment of obstetric fistula. The perspectives of healthcare providers involved in obstetric fistula treatment can assist policy makers to conceptualize and implement effective policies and programmes that will improve the quality of care offered to obstetric fistula survivors after their treatment. IMPLICATIONS FOR PRACTICES: These first-hand experiences and knowledge of healthcare providers are significant in identifying challenges and barriers that fistula survivors encounter during the reintegration process.

"Labia Majora Fasciocutaneous Flap Reconstruction in Complex Urogynecological Fistulas With Vaginal Deficit - A Versatile Approach".

OBJECTIVE: To appraise the pivotal points of different modifications of labia majora fasciocutaneous flap in combating the challenges of complex urogynecological fistula repair in the form of 7 cases. METHODS: Seven patients with complex urogynecological fistulas with vaginal deficit were treated over last 3 years. The challenges associated with them were non-capacious rigid vagina, irradiated and inflamed surrounding tissues, inelasticity, long-standing fistula with radiation-induced vesicovaginal fistula(VVF), an iatrogenic urethrovaginal fistula with anterior vaginal wall loss with vaginal stenosis, and a case of vesicolabial fistula with a history of forceps delivery and transvaginal VVF repair. Transvaginal repair with labia majora fasciocutaneous flap along with fat pad with relevant technical modifications was contemplated in all. RESULTS: All radiation-induced VVF patients demonstrated no leak in the postoperative period barring one who became dry after transvaginal colpocleisis later. The patient with urethrovaginal fistula and vaginal stenosis was continent, had capacious vagina, and without any leak with regular menstrual periods. The female with vesicolabial fistula remained dry at the end of 6-month follow-up. CONCLUSION: Transvaginal repair using the labia majora fasciocutaneous flap and the demonstrated technical modifications can be a feasible option in repairing complex urogynaecological fistulas associated with vaginal wall deficit.

Anatomical and functional outcomes of non-obstetric urogenital fistula repair.

INTRODUCTION AND HYPOTHESIS: Studies on non-obstetric urogenital fistulas (NOUGFs) provide limited information on predictive outcome factors. This study was aimed at specifying and analyzing the risk factors for long-term anatomical and functional results. METHODS: A cross-sectional study of surgical repair for non-obstetric urogenital fistula was performed. From 2012 to 2020, a total of 479 patients with urogenital fistulas were treated in two tertiary centers. Patients with isolated ureteral fistulas and rectal injuries were excluded. For evaluation of the long-term results, patients with vesicovaginal and urethrovaginal fistulas with at least 12 months of follow-up were identified and contacted by phone and/or examined in the clinic. The anatomical outcome was assessed by resolution of symptoms and/or clinical examination. The Urinary Distress Inventory (UDI-6) was used for the functional outcomes. RESULTS: Overall, 425 patients were studied (mean age was 49.8; BMI 27.5; mean fistula size 1.4 cm, mean follow-up was 12 months). Vesicovaginal fistula affected 73% of patients. Hysterectomy without radiation was the most common etiology (66.3%), followed by hysterectomy with subsequent radiation (16%) and pelvic radiotherapy (12.2%). The transvaginal approach was used in 54.4%, abdominal in 12.4%, transvesical in 22.4%, and a combined approach in 10.8%. The successful closure rate was 92.9% for primary cases, 71.6% for secondary cases, and 66.7% for radiation fistulas. A high risk for relapse was found for NOUGFs with ureteral involvement (RR 2.5; 95% CI 1.3-4.5; p = 0.003), radiation fistulas (RR 2.1; 95% CI 1.3-3.5, p = 0.003); and combined radiation and hysterectomy cases (RR 2.9; 95% CI 1.8-4.6; p = 0.0001). In multifactorial analysis, fistula size >3.0 cm, pelvic radiation, and previous vaginal surgeries were associated with a higher risk for failure or lower urinary symptoms. CONCLUSIONS: Factors for successful NOUGF closure are fistula size less than 3.0 cm, absence of pelvic radiation, and previous vaginal surgeries.

Uretero-vaginal fistulas - clinical presentation, treatment and literature overview.

A uretero-vaginal fistula (UVF) describes an abnormal connection between the ureter and vagina causing urinary incontinence, frequent infection, and discomfort. Although UVF might be diagnosed after vaginal delivery, infertility treatment or pelvic radiation therapy, gynecological operations, especially total abdominal hysterectomy, remain the leading cause of ureteral injury and formation of UVF. Traditional ureteroneocystostomy was usually the treatment of choice in patients with UVF. Nevertheless, it is now frequently replaced by less invasive endoscopic and percutaneous procedures which are also highly effective and feasible. That is why, ureteral stenting became the first-line treatment in uncomplicated UVF. The aim of this review is to present clinical presentation of UVF and to assess the current state of knowledge about the diagnosis and management of uretero-vaginal fistula with special interest on minimally-invasive methods.

Management strategies and outcome of ureterovaginal fistulae: A systematic review and meta-analysis.

BACKGROUND: Genitourinary fistula is a distressful condition involving mental, social, marital, and financial repercussions. OBJECTIVE: The objective of this study is to systematically evaluate etiology, clinical presentation, diagnosis, the timing of repair, and perform a meta-analysis evaluating the success rate of various treatment modalities with respect to time taken to seek treatment. SEARCH STRATEGY: We performed a critical review of PubMed/Medline, Embase, and the Cochrane Library in April 2020 according to the PRISMA statement. Seventeen studies were included in the final analysis and all were retrospective in design. SELECTION CRITERIA: Each article was rated by the evidence-based medicine levels of evidence scale and the Methodological Index for Nonrandomized Studies scale for assessment of bias among nonrandomized studies. MAIN RESULTS: Of the 799 fistulae reported in 17 studies, endoscopic management was done in 35.6% (12 studies), whereas surgical management was preferred in 85.6% fistulae (15 studies). The pooled success of endoscopic stenting was 32% (95% confidence interval [CI]: 7-64) and 100% (95% CI: 98-100) in operated patients. Patients who underwent stenting within 2 weeks (20%), 2-6 weeks (21%), and >6 weeks (40%) had pooled success rates of 95% (95% CI: 87-100), 46% (95% CI: 0-100), and 20% (95% CI: 1-49), respectively. Patients who underwent surgical management <6 weeks (15.9%) and >6 weeks (22%) of diagnosis had pooled success rates of 100% (95% CI: 99-100) and 100% (95% CI: 99-100), respectively. CONCLUSIONS: Stent placement as early as <6 weeks (preferably < 2 weeks) had better outcomes as compared to >6 weeks. Proceeding to surgery regardless of timing in cases of stent failure seems to be a feasible option.

Vaginal Complications after Cystectomy: Results from a Medicare Sample.

PURPOSE: Cystectomy with a vaginal-sparing approach may be associated with unique complications specific to the female population. The objective of this study was to estimate the incidence of vaginal complications (defined to include vaginal prolapse, vaginal fistula, dyspareunia and vaginal cuff dehiscence/evisceration) after cystectomy and to determine risk factors for these complications. MATERIALS AND METHODS: Women 65 years or older undergoing cystectomy for any indication were identified by procedural codes in the Medicare Limited Data Set 5% sample from January 1, 2011 to December 31, 2017. Patients experiencing a vaginal complication after cystectomy were compared to those who did not. Demographic and biological factors that could increase likelihood of complications were identified and time to development of complications determined. Cumulative incidence was calculated using cumulative incidence function. Multivariable cause-specific Cox proportional hazards model assessed risk factors for vaginal complications. RESULTS: In all, 481 women undergoing cystectomy were identified during the study period, and 37.2% were younger than 70 years old. The majority (378, 79%) had bladder cancer, and 401 (83.4%) underwent an incontinent conduit or catheterizable channel diversion. Within 2 years of cystectomy, 93 patients (19.5%) had 1 or more complications on record. Vaginal cuff dehiscence had the highest cumulative incidence, occurring in 49 patients (10.2%). Over the entire study period (2011-2017), 102 women (21.2%) were diagnosed with a vaginal complication, and 27 (5.6%) received an intervention. CONCLUSIONS: Among women who undergo cystectomy, vaginal complications occur at rates higher than expected with over 20% of women experiencing a complication and over a quarter of those diagnosed undergoing intervention.

Transvaginal primary layered repair of postsurgical urethrovaginal fistula.

INTRODUCTION AND HYPOTHESIS: Urethrovaginal fistula (UVF) is a rare disorder, which implies the presence of an abnormal communication between the urethra and the vagina. METHODS: Surgical repair options include transurethral, transabdominal and transvaginal procedures, either with or without tissue interposition. The vaginal route is considered a safe and effective option to correct UVF. This video is aimed to present a case of direct transvaginal layered repair of urethrovaginal fistula, without the use of tissue interposition. The featured patient is a 66-year-old woman who developed a symptomatic UVF after a complicated laparoscopic hysterectomy for endometrial cancer 3 years before. Cystoscopy demonstrated the presence of a 7 mm urethral orifice a few millimeters caudal from the bladder neck. After proper informed consent, the patient was admitted to transvaginal primary layered repair, according to the technique demonstrated in the video. The featured procedure was completed in 60 min and blood loss was < 100 ml. No surgical complications were observed. RESULTS: The procedure was successful in restoring the anatomy and relieving the symptoms. CONCLUSION: Transvaginal layered repair without tissue interposition represents a safe and effective procedure for the surgical management of postsurgical urethrovaginal fistula.

Vaginal repair of nonradiogenic urogenital fistulas.

INTRODUCTION AND HYPOTHESIS: In developed countries urogenital fistulas are rare and usually a complication of surgery or radiation therapy. Surgical repair can be accomplished transvaginally or by laparotomy, laparoscopy, robotic-assisted laparoscopy, or transurethral endoscopy. Closure can be achieved with or without tissue interposition. The vaginal approach is the least invasive and a variety of techniques with or without tissue interpositions and flaps have been described. This study reviews surgical approaches and techniques for the repair of nonradiogenic urogenital fistulas. METHODS: We identified and reviewed records from all patients treated for urogenital fistulas at our unit between 2008 and 2018. We analyzed fistula location, etiology, type and duration of corrective surgery, length of hospitalization, as well as complication and success rates. RESULTS: Fifty patients (mean age 52 years) were identified. 49 fistulas were related to previous gynecological surgery, 3 were related to obstetric trauma. Thirty-four patients had vesicovaginal, 11 urethrovaginal, 3 ureterovaginal, and 2 neobladder-vaginal fistulas. Forty-eight patients (96%) were operated on using a vaginal approach; a modified Sims-Simon repair was used in 47 cases (94%). No flaps or tissue interpositions were used. In 48 patients (96%) successful closure was achieved with one operation; the modified Sims-Simon technique was successful in all 47 cases. The median operation time was 40 min (range, 20-100 min); the complication rate was 14%. CONCLUSIONS: This series demonstrates the feasibility and advantages of vaginal repair of benign gynecological fistulas. The success rate was high and extensive procedures were avoided.

Feasibility of robotic radical hysterectomy (RRH) with a new robotic system. Experience at Galaxy Care Laparoscopy Institute.

The main objective of this study was to assess in a series of 30 patients, the feasibility, oncological safety and efficacy of radical hysterectomy by a new robotic system. Prospective study design. Galaxy Care Laparoscopy Institute and Multispeciality Hospital. We performed Robotic Radical Hysterectomy in patients from August 2019 through February 2020. All the surgeries were performed by a single surgeon (Puntambekar S). Since August 2019, 30 patients with early cervical cancer/endometrial cancer were selected for radical hysterectomy. All patients were in good general condition with controlled medical comorbidities. The mean operative time was 104 min, with mean total lymph node yield of 24.7. The average blood loss was 60 ml and the hospital stay was 2.1 days, and majority of the patients were catheter free by 1 week. Two patients developed uretero-vaginal fistula on the 8th day of surgery. One was managed with Double J stenting and in the other we did laparoscopic ureteroneocystostomy. Our study has demonstrated the feasibility, safety and efficacy of RRH by the Versius robotic systems.

Early detection and endoscopic management of post cesarean section ureterovaginal fistula: a case series study.

INTRODUCTION AND HYPOTHESIS: The aim of this study was to evaluate the endourologic management of post-cesarean section ureterovaginal fistula. METHODS: Between February 2016 and March 2019, eight patients presented because of vaginal leakage after cesarean section. All presented within 15 days from their original operations. Three of the patients had a vague lower abdominal pain, and five had ipsilateral flank pain; all had vaginal leakage. Physical examination, ultrasonography, and IVP were done to confirm the diagnosis. Ureteroscopy was the first treatment attempt, using two or three guide wires to find the proximal part of the ureter and insert a JJ stent. RESULTS: In six patients, we could insert guide wires, find the proximal part of the ureter, and finally insert a JJ stent. In two patients, we could not even pass a guide wire, so we changed the position, and ureteral reimplantation was done. The stents were removed after 6 weeks, and after 3 months an IVP was planned again that showed all fistulae had resolved with no evidence of ureteral stricture. CONCLUSION: In cases of ureterovaginal fistula after cesarean section, ultrasonography and IVP with lateral view x-ray films may confirm the diagnosis. The traditional treatment for ureterovaginal fistula is ureteral reimplantation, but endoscopic management may be a viable technique with less invasiveness and faster results and recovery. Thus, retrograde stenting can be accomplished in selected patients with ureterovaginal fistula after cesarean section and may eliminate the need for reimplantation of the ureter.

Systematic review on the management of ileoanal pouch-vaginal fistulas after restorative proctocolectomy in the treatment of ulcerative colitis.

AIM: Ileoanal pouch-vaginal fistula (PVF) is a relatively common complication of restorative proctocolectomy with ileal pouch-anal anastomosis. There are several operative approaches in the management of PVF. There is currently no consensus as to which approach is the most effective or which should be attempted first. METHOD: A systematic review was undertaken following a publicly available protocol registered with PROSPERO (CRD42019133750) in accordance with PRISMA guidelines. Online searches of databases MEDLINE and Embase, Cochrane Library, ClinicalTrials.gov, EU Clinical Trials and ISRCTN registry were performed. RESULTS: Twenty-seven articles met the criteria for inclusion in the study: 13 retrospective cohort studies, two prospective cohort studies, eight case series, three case reports and a case-control study. A narrative synthesis was performed due to heterogeneity between included articles. Our study included 577 PVFs, and the incidence rate was 2.1%-17.1%. Both local and abdominal approaches were used in the management of PVF. The overall success of local and abdominal procedures was 44.9% and 60.2% respectively. ROBINS-I assessment revealed a critical risk of bias. GRADE assessment indicated a very low certainty in effect size and evidence quality. CONCLUSION: Local interventions and abdominal approaches have a high failure rate. The results of this review will aid the counselling of patients with this condition. Furthermore, we provide an algorithm for discussion on the management of PVF based on experience at our local centre. The studies available on the management of PVF are low quality; a large prospective registry and Delphi consensus are required to further this area of research.

Transvaginal repair of neobladder vaginal fistula with martius flap

ABSTRACT Introduction: Neobladder vaginal fistula (NVF) is a known complication after cystectomy and orthotopic diversion in women, occurring in 3-5% of women. Possible risk factors for fistula formation include compromised tissue vascularity due to surgical dissection and/or radiotherapy, suture line proximity, local tissue recurrence, and injury to the vaginal wall during dissection. The surgical repair of a NVF can be challenging secondary to vaginal shortening, atrophy, local inflammation from chronic exposure to urinary leakage, and the proximity of the neobladder to the anterior vaginal wall. In this video, we present transvaginal repair of a NVF with Martius flap interposition. Materials and Methods: This is the case of a 47 year old woman with a history of radical cystectomy and creation of a Studer pouch secondary to bladder cancer two years prior who subsequently developed a NVF. Evaluation included an office cystoscopy which demonstrated a 3-4mm left-sided neobladder vaginal fistula at the level of the ileal-urethral anastomosis. No pelvic organ prolapse or evidence of bladder cancer recurrence was appreciated. Results: A vaginal approach for the NVF repair was performed with a Martius flap interposition. A water-tight closure was achieved without any intraoperative or immediate postoperative complications. The urethral Foley was removed at 2 weeks and by 4 weeks the patient did not report any urinary leakage. Conclusions: Neobladder vaginal fistula is a rare complication following cystectomy and orthotopic urinary diversion that can be repaired using a transvaginal approach. A Martius flap interposition is important to augment success of the repair. If a transvaginal approach fails a transabdominal approach or conversion to cutaneous diversion may be necessary.

Primary results from CECILIA, a global single-arm phase II study evaluating bevacizumab, carboplatin and paclitaxel for advanced cervical cancer.

OBJECTIVE: Adding bevacizumab to cisplatin-paclitaxel for advanced cervical cancer significantly improves overall and progression-free survival. We evaluated bevacizumab with a widely used carboplatin-paclitaxel backbone. METHODS: Patients with metastatic/recurrent/persistent cervical cancer not amenable to curative surgery and/or radiotherapy received 3-weekly bevacizumab 15 mg/kg, paclitaxel 175 mg/m2, and carboplatin AUC 5 until progression or unacceptable toxicity. Maintenance bevacizumab was allowed. Patients with ongoing bladder/rectal involvement, prior cobalt radiotherapy, a history of fistula/gastrointestinal perforation, or recent bowel resection/chemoradiation were excluded. The primary objective was to determine incidences of gastrointestinal perforation/fistula, gastrointestinal-vaginal fistula, and genitourinary fistula. RESULTS: Among 150 treated patients, disease at study entry was persistent in 21%, recurrent in 56%, and newly diagnosed metastatic in 23%. After 27.8 months' median follow-up, median bevacizumab duration was 6.7 months; 57% received maintenance bevacizumab. Seventeen patients (11.3%; 95% CI: 6.7-17.5%) experienced ≥1 perforation/fistula event: gastrointestinal perforation/fistula in 4.7% (1.9-9.4%), gastrointestinal-vaginal fistula in 4.0% (1.5-8.5%), and genitourinary fistula in 4.7% (1.9-9.4%). Of these, 16 were previously irradiated, several with ongoing radiation effects. The most common grade 3/4 adverse events were neutropenia (25%), anemia (19%), and hypertension (14%). Five patients (3%) had fatal adverse events. Objective response rate was 61% (95% CI: 52-69%), median progression-free survival was 10.9 (10.1-13.7) months, and median overall survival was 25.0 (20.9-30.4) months. CONCLUSIONS: Bevacizumab can be combined with carboplatin-paclitaxel in the CECILIA study population. The fistula/gastrointestinal perforation incidence is in line with GOG-0240; efficacy results are encouraging. TRIAL REGISTRATION NUMBER: NCT02467907 (ClinicalTrials.gov).
