RESUMEN
BACKGROUND: The exstrophy-epispadias complex is a spectrum of ventral wall malformations including classic bladder exstrophy (CBE) and cloacal exstrophy (CE). Patients undergo multiple soft-tissues procedures to achieve urinary continence. If unsuccessful bladder neck closure (BNC) is performed, muscle flaps may be used to reinforce BNC or afterwards for fistula reconstruction. In this study, patients reconstructed using a rectus abdominis or gracilis muscle flap were reviewed. METHODS: A retrospective cohort study of exstrophy-epispadias complex patients who underwent BNC and had a muscle fap was performed. Indication for flap use, surgical technique, risks for BNC failure including mucosal violations (MVs) were reviewed. MVs were prior bladder mucosa manipulation for exstrophy closure, repeat closure(s) and bladder neck reconstruction. Success was defined as BNC without fistula development. RESULTS: Thirty-four patients underwent reconstruction. Indications included during BNC (n=13), fistula closure after BNC (n=17), following BNC during open cystolithotomy (n=1) or fistula closure after open cystolithotomy (n=3). A vesicourethral fistula developed most frequently in CBE (88.9%) and vesicoperineal fistula in CE (87.5%). Thirty-three rectus flaps and 3 gracilis flap were used with success achieved in 97.1% and 66.7%, respectively. All 34 patients achieved success and 2 CE patients required a second flap. CONCLUSION: The rectus flap is preferred as it covers the antero-inferior bladder and pelvic floor to prevent urethral, cutaneous, and perineal fistula formation. The gracilis flap only reaches the pelvic floor to prevent urethral and perineal fistula development. Increased MVs, increase the risk of fistula formation and may influence the need for prophylactic flaps.
RESUMEN
BACKGROUND: Cloacal exstrophy (CE) is rare and challenging to reconstruct. In the majority of CE patients voided continence cannot be achieved and so patients often undergo bladder neck closure (BNC). Prior mucosal violations (MVs), a surgical event when the bladder mucosa was opened or closed, significantly predicted failed BNC in classic bladder exstrophy with an increased likelihood of failure after 3 or more MVs. The aim of this study was to assess predictors for failed BNC in CE. METHODS: CE patients who underwent BNC were reviewed for risk factors for failure including osteotomy use, successful primary closure, and number of MVs. Chi-squared and Fisher's exact tests were used for comparing baseline characteristics and surgical details. RESULTS: Thirty-five patients underwent BNC. Eleven patients (31.4%) failed BNC including a vesicoperineal fistula in nine, vesicourethral and vesicocutaneous fistula in one each. The fistula rate in patients with 2 or more MVs was 47.4% (p = 0.0252). Two patients subsequently developed a vesicocutaneous fistula after undergoing repeated cystolithotomies. A rectus abdominis or gracilis muscle flap were used to close the fistula in 11 and 2 patients, respectively. CONCLUSIONS: MVs have a greater impact in CE with an increased risk of failed BNC after 2 MVs. CE patients are most likely to develop a vesicoperineal fistula while a vesicocutaneous fistula is more likely after repeat cystolithotomy. A prophylactic muscle flap should be considered at time of BNC in patients with 2 or more MVs. LEVELS OF EVIDENCE: Prognosis Study, Level III.

INTRODUCTION: Restoration of genitourinary anatomy with functional urinary continence is the reconstruction aim is the exstrophy-epispadias complex (EEC). In patients who do not achieve urinary continence or those who are not a candidate for bladder neck reconstruction (BNR), bladder neck closure (BNC) is considered. Interposing layers including human acellular dermis (HAD) and pedicled adipose tissue are routinely placed between the transected bladder neck and distal urethral stump to reinforce the BNC and minimize failure due to fistula development from the bladder. OBJECTIVE: The aim of this study was to review classic bladder exstrophy (CBE) patients who underwent BNC to identify predictors of BNC failure. Specifically, we hypothesize that increased operations on the bladder urothelium leads to a higher rate of urinary fistula. STUDY DESIGN: CBE patients who underwent BNC were reviewed for predictors of failed BNC which was defined as bladder fistula development. Predictors included prior osteotomy, interposing tissue layer use and number of previous bladder mucosal violations (MV). A MV was defined as a procedure when the bladder mucosa was opened or closed for: exstrophy closure(s), BNR, augmentation cystoplasty or ureteral re-implantation. Predictors were evaluated using multivariate logistic regression. RESULTS: A total of 192 patients underwent BNC of which 23 failed. Patients were more likely to develop a fistula with a wider pubic diastasis at time of primary exstrophy closure (4.4 vs 4.0 cm, p=0.0016), have failed exstrophy closure (p=0.0084), or have 3 or more MVs before BNC (p=0.0002). Kaplan-Meier analysis of fistula-free survival after BNC, demonstrated an increased fistula rate with additional MVs (p=0.0004, Figure 1). MVs remained significant on multivariate logistic regression analysis with a per-violation odds ratio of 5.1 (p<0.0001). Of the 23 failed BNC's, 16 were surgically closed including 9 using a pedicled rectus abdominis muscle flap which was secured to the bladder and pelvic floor. CONCLUSION: This study conceptualized MVs and their role in bladder viability. Increased MVs confer an increased risk of failed BNC. When considering BNC, CBE patients with 3 or more prior MVs may benefit from a pedicled muscle flap, in addition to HAD and pedicled adipose tissue, to prevent fistula development by providing wellvascularized coverage to further reinforce the BNC.

BACKGROUND: Standards for reporting surgical adverse events (AEs) vary widely within the scientific literature. Failure to adequately capture AEs hinders efforts to measure the safety of healthcare delivery and improve the quality of care. The aim of the present study is to assess the prevalence and typology of perioperative AE reporting guidelines among surgery and anesthesiology journals. MATERIALS AND METHODS: In November 2021, three independent reviewers queried journal lists from the SCImago Journal & Country Rank (SJR) portal (www.scimagojr.com), a bibliometric indicator database for surgery and anesthesiology academic journals. Journal characteristics were summarized using SCImago, a bibliometric indicator database extracted from Scopus journal data. Quartile 1 (Q1) was considered the top quartile and Q4 bottom quartile based on the journal impact factor. Journal author guidelines were collected to determine whether AE reporting recommendations were included and, if so, the preferred reporting procedures. RESULTS: Of 1409 journals queried, 655 (46.5%) recommended surgical AE reporting. Journals most likely to recommend AE reporting were: by category surgery (59.1%), urology (53.3%), and anesthesia (52.3%); in top SJR quartiles (i.e. more influential); by region, based in Western Europe (49.8%), North America (49.3%), and the Middle East (48.3%). CONCLUSIONS: Surgery and anesthesiology journals do not consistently require or provide recommendations on perioperative AE reporting. Journal guidelines regarding AE reporting should be standardized and are needed to improve the quality of surgical AE reporting with the ultimate goal of improving patient morbidity and mortality.

BACKGROUND: Bladder cancer is the most expensive cancer to treat on a per-patient basis. Blue light cystoscopy with hexaminolevulinate (BLC) has demonstrated improved diagnostic accuracy compared with white light cystoscopy (WLC) in non-muscle invasive bladder cancer (NMIBC). With higher upfront costs, questions remain about long-term BLC cost outcomes. OBJECTIVE: This study seeks to investigate the 5-year cost comparison of BLC and WLC from the Medicare payer perspective. METHODS: A representative 5-year NMIBC management model was constructed and Medicare reimbursement values were overlaid. The primary outcome was mean year-over-year cumulative cost discounted to present value at a 3% annual percentage rate. The secondary outcome was the rate of clinical events. RESULTS: Patients in the BLC cohort experienced fewer recurrences. On a cumulative present value cost basis, BLC was more expensive per patient in years 1, 2, and 3 than WLC, however, in years 4 and 5, BLC was economically favorable. Year 5 BLC mean cumulative cost savings was $1,172 per patient. Overall, 31.6% of all patients in the BLC group generated cumulative cost savings compared to WLC at year 1 compared with 50.9% at the end of year 5. CONCLUSIONS: Despite a higher initial annual cost, a slight cumulative economic advantage of BLC is realized after surveillance year 3. Additionally, a greater proportion of patients who received BLC achieved cost savings at the end of year 5. As novel technology emerges, economic models can help health care systems predict associated costs and quality improvements.
RESUMEN
BACKGROUND: The addition of pelvic osteotomy to the armamentarium of tools for correction of classic bladder exstrophy (CBE) and cloacal exstrophy (CE) has undeniably served as one of the most effective advancements in improving the likelihood of successful primary bladder closure. Osteotomy-related complications have been studied and documented extensively in patients with CBE, yet evaluation remains limited in CE concordant with its relative rarity. OBJECTIVE: To compare orthopedic complications in patients with CBE and CE who underwent primary bladder closure with osteotomy. METHODS: A prospectively maintained, IRB-approved database of 1401 exstrophy-epispadias patients was reviewed for patients with CBE or CE after primary closure and pelvic osteotomy performed at a single institution from 1975 to 2021. Failed closure was defined as dehiscence, bladder prolapse, or vesicocutaneous fistula at any point. Surgery or anesthesia-related complications were captured within 6 weeks of osteotomy or closure. RESULTS: A total of 146 patients were included in the analysis with 109 and 37 patients with CBE and CE, respectively. Between the CBE and CE cohorts, there were significant differences in median age at primary closure (68 days [IQR 10-260] vs 597 [448-734]; p < 0.001), diastasis width (4 cm IQR [3.8-4.6] vs 6.1 [5.0-7.2]; p < 0.001), osteotomy at time of closure (99.1% vs 75.7%; p < 0.001), and utilization of external hip fixation (67.9% vs 89.2%; p = 0.011). There was no significant difference by gender, osteotomy technique, or hip immobilization technique. Regarding exstrophy closure outcomes, there were 5 failures in the CBE group and 1 in the CE group (p = 1.000). Complications were experienced in 38.5% and 56.8% of CBE and CE patients (p = 0.054) with a significant difference in orthopedic complications (primarily consisting of superficial pin-site infections) between the cohorts (4.6% vs 16.2%, p = 0.031). There was no significant difference in grade 3 or higher complications between cohorts (5.5% vs 13.5%, p = 0.147). DISCUSSION: This was the first study comparing orthopedic complications after osteotomy between CBE and CE, providing valuable insight into which factors vary among cohorts and which are associated with increased complication rates. Despite availability of high case numbers for these rare disorders, the analysis continued to be limited sample size and missing data for retrospective analysis. CONCLUSIONS: While exstrophy closure success and overall complications rates are similar in patients with CBE and CE, patients with CE experience more superficial pin-site infections after pelvic osteotomy. External hip fixation may be associated with the increase in orthopedic complications, though further research is required to elucidate the underlying cause of these complications.

Introduction and Objectives: In patients with localized prostate cancer, 5-fraction, stereotactic body radiation therapy (SBRT) has been found to offer comparable oncologic outcomes and potential for improved treatment compliance compared to conventional, 40-plus fraction radiation therapy (RT). Recent studies of oncologic patient experiences have highlighted both the impact of therapy-associated financial toxicity (FT) on treatment adherence and health-related quality of life (HRQOL). Methods: A cross-sectional assessment of FT after SBRT was performed using the 12-item COST questionnaire. The total questionnaire score (range 0-44) was used to evaluate the FT grade (0-3), with a higher COST value representing lower grade. The patient zip code was used to approximate the distance from the index hospital. Univariate and multivariate analyses of the average COST score (0-4) are performed. Results: The response rate was 57.5% (332 of 575 consented patients) with 90.7%, 8.2%, and 1.1% experiencing grade 0, 1, and 2 FT, respectively, with no grade 3. Unemployment or disability, non-white race, low income, and concurrent hormonal therapy were associated with a statistically significant worse FT (lower COST value) on univariate and multivariate analyses (p < 0.05). Education level and insurance status significant were evaluated on univariate analysis only. There was a non-statistically significant difference in age, marital status, time since treatment, and distance from the index hospital. Conclusions: SBRT was associated with low FT. However, statistically significant socioeconomic disparities in FT remain despite ultra-hypofractionated treatment.
RESUMEN
Introduction: Stereotactic Body Radiation Therapy (SBRT) has emerged as a definitive therapy for localized prostate cancer (PCa). However, more data is needed to predict patient prognosis to help guide which patients will benefit most from treatment. The FACIT-Fatigue (FACIT-F) is a well validated, widely used survey for assessing fatigue. However, the role of fatigue in predicting PCa survival has yet to be studied. Herein, we investigate the role of FACIT-F as a baseline predictor for overall survival (OS) in patients undergoing SBRT for localized PCa. Methods: A retrospective review was conducted of 1358 patients who received SBRT monotherapy between January 2008 to April 2021 at an academic, tertiary referral center. FACIT-F scores (range 0 to 52) were summed for patients who answered all 13-items on the survey. FACIT-F total scores of ≥35 represented severe fatigue. Patients receiving androgen deprivation therapy were excluded. Differences in fatigue groups were evaluated using chi-squared tests. OS rates were determined using the Kaplan-Meier method and predictors of OS were evaluated using Cox proportional hazard method. Results: Baseline full FACIT-F scores and survival data was available for 891 patients. 5-year OS was 87.6% and 95.2%, respectively, for the severely fatigued and non-fatigued groups. Chi-squared analysis of fatigue groups showed no significant difference in the following categories: D'Amico risk group, age, ethnicity, grade group, T-stage, or PSA density. Severe fatigue was associated with a significant decrease in OS (hazard ratio 2.76; 95%CI 1.55 - 4.89). The Cox proportional hazard model revealed that age and FACIT-F were both statistically significant (p <0.05). Conclusion: Baseline FACIT-F scores are significantly associated with OS. Higher FACIT-F scores, representing less fatigued patients, are associated with an overall survival benefit. These results indicate that the FACIT-F survey could serve as an additional metric for clinicians in determining prognostic factors for patients undergoing SBRT.
RESUMEN
Despite early detection and regular surveillance of non-muscle invasive bladder cancer (NMIBC), recurrence and progression rates remain exceedingly high for this highly prevalent malignancy. Limited visualization of malignant lesions with standard cystoscopy and associated false-negative biopsy rates have been the driving force for investigating alternative and adjunctive technologies for improved cystoscopy. The aim of our systematic review and meta-analysis was to compare the sensitivity, specificity, and oncologic outcomes of photodynamic diagnosis (PDD) fluorescence, narrow band imaging (NBI), and conventional white light cystoscopy (WLC) in detecting NMIBC. Out of 1,087 studies reviewed, 17 prospective non-randomized and randomized controlled trials met inclusion criteria for the study. We demonstrated that tumor resection with either PDD and NBI exhibited lower recurrence rates and greater diagnostic sensitivity compared to WLC alone. NBI demonstrated superior disease sensitivity and specificity as compared to WLC and an overall greater hierarchical summary receiver operative characteristic. Our findings are consistent with emerging guidelines and underscore the value of integrating these enhanced technologies as a part of the standard care for patients with suspected or confirmed NMIBC.
