Prophylactic Use of Biologic Mesh in Ileal Conduit (PUBMIC): A Randomized Clinical Trial.

PURPOSE: We assessed the effect of prophylactic biologic mesh on parastomal hernia (PSH) development in patients undergoing cystectomy and ileal conduit (IC). MATERIALS AND METHODS: This phase 3, randomized, controlled trial (NCT02439060) included 146 patients who underwent cystectomy and IC at the University of Southern California between 2015 and 2021. Follow-ups were physical exam and CT every 4 to 6 months up to 2 years. Patients were randomized 1:1 to receive FlexHD prophylactic biological mesh using sublay intraperitoneal technique vs standard IC. The primary end point was time to radiological PSH, and secondary outcomes included clinical PSH with/without surgical intervention and mesh-related complications. RESULTS: The 2 arms were similar in terms of baseline clinical features. All surgeries and mesh placements were performed without any intraoperative complications. Median operative time was 31 minutes longer in patients who received mesh, yet with no statistically significant difference (363 vs 332 minutes, P = .16). With a median follow-up of 24 months, radiological and clinical PSHs were detected in 37 (18 mesh recipients vs 19 controls) and 16 (8 subjects in both arms) patients, with a median time to radiological and clinical PSH of 8.3 and 15.5 months, respectively. No definite mesh-related adverse events were reported. Five patients (3 in the mesh and 2 in the control arm) required surgical PSH repair. Radiological PSH-free survival rates in the mesh and control groups were 74% vs 75% at 1 year and 69% vs 62% at 2 years. CONCLUSIONS: Implementation of biologic mesh at the time of IC construction is safe without significant protective effects within 2 years following surgery.

Study protocol for the Intraoperative Complications Assessment and Reporting with Universal Standards (ICARUS) global cross-specialty surveys and consensus.

Annually, about 300 million surgeries lead to significant intraoperative adverse events (iAEs), impacting patients and surgeons. Their full extent is underestimated due to flawed assessment and reporting methods. Inconsistent adoption of new grading systems and a lack of standardization, along with litigation concerns, contribute to underreporting. Only half of relevant journals provide guidelines on reporting these events, with a lack of standards in surgical literature. To address these issues, the Intraoperative Complications Assessment and Reporting with Universal Standard (ICARUS) Global Surgical Collaboration was established in 2022. The initiative involves conducting global surveys and a Delphi consensus to understand the barriers for poor reporting of iAEs, validate shared criteria for reporting, define iAEs according to surgical procedures, evaluate the existing grading systems' reliability, and identify strategies for enhancing the collection, reporting, and management of iAEs. Invitation to participate are extended to all the surgical specialties, interventional cardiology, interventional radiology, OR Staffs and anesthesiology. This effort represents an essential step towards improved patient safety and the well-being of healthcare professionals in the surgical field.

Robotic Management of Complex Vesicourethral Anastomosis Stenosis With Transperineal Urethral Advancement: A Step-by-Step Technique.

BACKGROUND: Vesicourethral anastomosis stenosis (VUAS) refers to the diameter narrowing of a vesicourethral anastomosis (VUA). It is a known complication after radical prostatectomy that nowadays presents in less than 1% of these cases. When the lumen narrows sufficiently to impede urine flow, obstructive symptoms arise. While the incidence of VUAS used to be notably higher prior to the widespread use of the robotic approach, traditional procedures still fail in up to 42% of cases. Initial management typically involves endoscopic procedures, such as dilation, incision, or resection. If these approaches prove ineffective, VUA reconstruction is warranted. Following the resection of the unhealthy urethra, a potential drawback is the insufficient length of the healthy proximal urethral to reach the bladder without tension. In such cases, urinary diversion with an ileal conduit is an option. However, when the patient prefers to maintain an orthotopic urinary tract configuration, there is limited guidance in the literature regarding surgical techniques. OBJECTIVE: To outline the indications, describe the step-by-step technique, and evaluate the outcomes of transperineal urethral advancement to facilitate a tension-free VUA. MATERIALS: We first discuss the indications to identify which patients are candidates for this procedure. Then, a step-by-step description of the robotic VUA revision assisted by transperineal urethral mobilization is presented. Detailed steps and helpful hints are included. Finally, we outline the postoperative pathway and expected outcomes. RESULTS: This technique allows patients with VUAS to preserve the orthotopic configuration of the urinary tract when a tension-free anastomosis proves challenging. Although urinary incontinence is expected, an artificial urinary sphincter could be placed in the following months. CONCLUSION: The robotic management of complex vesicourethral anastomosis stenosis with transperineal urethral advancement is a feasible and safe procedure that requires the interdisciplinary management of robotic and reconstructive urologists.

Long-term oncological and surgical outcomes after Video Endoscopic Inguinal Lymphadenectomy (VEIL) in patients with penile cancer

ABSTRACT Objective: To report outcomes from the largest multicenter series of penile cancer patients undergoing video endoscopic inguinal lymphadenectomy (VEIL). Materials and Methods: Retrospective multicenter analysis. Authors of 21 centers from the Penile Cancer Collaborative Coalition-Latin America (PeC-LA) were included. All centers performed the procedure following the same previously described standardized technique. Inclusion criteria included penile cancer patients with no palpable lymph nodes and intermediate/high-risk disease and those with non-fixed palpable lymph nodes less than 4 cm in diameter. Categorical variables are shown as percentages and frequencies whereas continuous variables as mean and range. Results: From 2006 to 2020, 210 VEIL procedures were performed in 105 patients. Mean age was 58 (45-68) years old. Mean operative time was 90 minutes (60-120). Mean lymph node yield was 10 nodes (6-16). Complication rate was 15.7%, including severe complications in 1.9% of procedures. Lymphatic and skin complications were noted in 8.6 and 4.8% of patients, respectively. Histopathological analysis revealed lymph node involvement in 26.7% of patients with non-palpable nodes. Inguinal recurrence was observed in 2.8% of patients. 10y- overall survival was 74.2% and 10-y cancer specific survival was 84.8%. CSS for pN0, pN1, pN2 and pN3 were 100%, 82.4%, 72.7% and 9.1%, respectively. Conclusion: VEIL seems to offer appropriate long term oncological control with minimal morbidity. In the absence of non-invasive stratification measures such as dynamic sentinel node biopsy, VEIL emerged as the alternative for the management of non-bulky lymph nodes in penile cancer.

Severity Grading Systems for Intraoperative Adverse Events. A Systematic Review of the Literature and Citation Analysis.

INTRODUCTION: The accurate assessment and grading of adverse events (AE) is essential to ensure comparisons between surgical procedures and outcomes. The current lack of a standardized severity grading system may limit our understanding of the true morbidity attributed to AEs in surgery. The aim of this study is to review the prevalence in which intraoperative adverse event (iAE) severity grading systems are used in the literature, evaluate the strengths and limitations of these systems, and appraise their applicability in clinical studies. METHODS: A systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. PubMed, Web of Science, and Scopus were queried to yield all clinical studies reporting the proposal and/or the validation of iAE severity grading systems. Google Scholar, Web of Science, and Scopus were searched separately to identify the articles citing the systems to grade iAEs identified in the first search. RESULTS: Our search yielded 2957 studies, with 7 studies considered for the qualitative synthesis. Five studies considered only surgical/interventional iAEs, while 2 considered both surgical/interventional and anesthesiologic iAEs. Two included studies validated the iAE severity grading system prospectively. A total of 357 citations were retrieved, with an overall self/nonself-citation ratio of 0.17 (53/304). The majority of citing articles were clinical studies (44.1%). The average number of citations per year was 6.7 citations for each classification/severity system, with only 2.05 citations/year for clinical studies. Of the 158 clinical studies citing the severity grading systems, only 90 (56.9%) used them to grade the iAEs. The appraisal of applicability (mean%/median%) was below the 70% threshold in 3 domains: stakeholder involvement (46/47), clarity of presentation (65/67), and applicability (57/56). CONCLUSION: Seven severity grading systems for iAEs have been published in the last decade. Despite the importance of collecting and grading the iAEs, these systems are poorly adopted, with only a few studies per year using them. A uniform globally implemented severity grading system is needed to produce comparable data across studies and develop strategies to decrease iAEs, further improving patient safety.

Bibliometric analysis of academic journal recommendations and requirements for surgical and anesthesiologic adverse events reporting.

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.

Robotic-assisted repair of colovesical anastomosis after Hartmann's reversal procedure

ABSTRACT Purpose Hartmann's procedure is the resection of the rectosigmoid colon with an end colostomy formation and closure of the anorectal stump (1). Its reversal has a morbidity rate up to 58% (2, 3) with an incidence of fistulae formation of 4.08% (1). Herein, we present a robotic-assisted repair of a complex fistula that occurred as complication of Hartmann's reversal when the stapler was introduced inadvertently through the vaginal canal. Patient and methods Eighty-three-year-old female with past medical history of hysterectomy and ischemic colitis that required colectomy and colostomy placement in December 2020. In March 2022, the patient underwent a colostomy takedown, after which she reported fecaluria, urine leakage per vagina, and recurrent urinary tract infections. Cystoscopy and vaginoscopy revealed a large colovesical fistula, a staple in the bladder trigone, and several staples in the anterior vaginal wall. Robotically, extensive adhesiolysis was performed, the sigmoid was separated from the bladder, and the intact rectal stump was dissected free. The staple from the bladder trigone was removed. Bladder was closed in two layers with 3-0 V-Loc. Colorectal anastomosis was not feasible due to the short length of both ends. Therefore, a permanent colostomy was placed. Results Operative time was 454min., and estimated blood loss was 100cc. Discharged on postoperative day 4 with a JP drain and a 20Fr Foley catheter. Drain, and Foley were removed on postoperative days 9 and 23, respectively. No postoperative complications were reported. Conclusion Robotic-assisted repair represents an effective approach for the management of colovesical fistulae after Hartmann's reversal.

Robotic-assisted Simple Prostatectomy: An Intrafascial Approach for a Prostate of 470 g.

BACKGROUND: Simple prostatectomy has been established as a management option for lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) with glands larger than 80 cc.1 Robotic-assisted simple prostatectomy (RASP) has been established as a safe and effective management option. This has been reported in multiple studies comparing it with the open approach where no statistically significant differences in complication rates have been found.2 The intrafascial approach is intended to add multiple benefits, such as not requiring continuous bladder irrigation and resection of a larger percentage of the adenoma, potentially leading to a lower reoperation rate and diagnosis of prostate cancer in patients in which this was missed preoperatively.3 OBJECTIVE: To present the resection of a very large prostate can lead to significant intraoperative challenges. Therefore, we demosntrate our intrafascial robotic management of a 470g prostate. MATERIALS AND METHODS: A 56-year-old with LUTS (IPSS: 34) for over 6 years, complicated with multiple episodes of urinary retention. PSA: 20.6 ng/mL. MRI reported a 463 cc prostate volume without focal lesions. First, the retropubic space was developed. Cystotomy was performed at the anterior bladder neck. A plane between the prostatic capsule and the surrounding fascia was dissected while carefully preserving the neurovascular bundles. Due to its large size, the prostate was divided into segments to facilitate its extraction. Hemostatic control and vesicourethral anastomosis were performed. RESULTS: Discharged on postoperative day 1 with a Jackson-Pratt drain and Foley catheter removed on days 6 and 9, respectively. Pathology was negative for malignancy. Patient-reported improvement of LUTS (IPSS: 3) and preservation of erectile function (SHIM: 23) at the 3-month follow-up. CONCLUSION: The intrafascial technique can be useful in cases where a large-sized prostate hinders a transvesical approach. Additionally, it allows for an easier piecemeal of the gland. A larger series is needed to determine its potential benefits.

Recommendations for Intraoperative Adverse Events Data Collection in Clinical Studies and Study Protocols. An ICARUS Global Surgical Collaboration Study.

Introduction: Intraoperative adverse events (iAEs) occur and have the potential to impact the postoperative course. However, iAEs are underreported and are not routinely collected in the contemporary surgical literature. There is no widely utilized system for the collection of essential aspects of iAEs, and there is no established database for the standardization and dissemination of this data that likely have implications for outcomes and patient safety. The Intraoperative Complication Assessment and Reporting with Universal Standards (ICARUS) Global Surgical Collaboration initiated a global effort to address these shortcomings, and the establishment of an adverse event data collection system is an essential step. In this study, we present the core-set variables for collecting iAEs that were based on the globally validated ICARUS criteria for surgical/interventional and anesthesiologic intraoperative adverse event collection and reporting. Material and Methods: This article includes three tools to capture the essential aspects of iAEs. The core-set variables were developed from the globally validated ICARUS criteria for reporting iAEs (item 1). Next, the summary table was developed to guide researchers in summarizing the accumulated iAE data in item 1 (item 2). Finally, this article includes examples of the method and results sections to include in a manuscript reporting iAE data (item 3). Then, 5 scenarios demonstrating best practices for completing items 1-3 were presented both in prose and in a video produced by the ICARUS collaboration. Dissemination: This article provides the surgical community with the tools for collecting essential iAE data. The ICARUS collaboration has already published the 13 criteria for reporting surgical adverse events, but this article is unique and essential as it actually provides the tools for iAE collection. The study team plans to collect feedback for future directions of adverse event collection and reporting. Highlights: This article represents a novel, fully-encompassing system for the data collection of intraoperative adverse events.The presented core-set variables for reporting intraoperative adverse events are not based solely on our opinion, but rather are synthesized from the globally validated ICARUS criteria for reporting intraoperative adverse events.Together, the included text, figures, and ICARUS collaboration-produced video should equip any surgeon, anesthesiologist, or nurse with the tools to properly collect intraoperative adverse event data.Future directions include translation of this article to allow for the widest possible adoption of this important collection system.

A Urine-based DNA Methylation Marker Test to Detect Upper Tract Urothelial Carcinoma: A Prospective Cohort Study.

PURPOSE: We explored the accuracy of a urine-based epigenetic test for detecting upper tract urothelial carcinoma. MATERIALS AND METHODS: Under an Institutional Review Board-approved protocol, urine samples were prospectively collected from primary upper tract urothelial carcinoma patients before radical nephroureterectomy, ureterectomy, or ureteroscopy between December 2019 and March 2022. Samples were analyzed with Bladder CARE, a urine-based test that measures the methylation levels of 3 cancer biomarkers (TRNA-Cys, SIM2, and NKX1-1) and 2 internal control loci using methylation-sensitive restriction enzymes coupled with quantitative polymerase chain reaction. Results were reported as the Bladder CARE Index score and quantitatively categorized as positive (>5), high risk (2.5-5), or negative (<2.5). The findings were compared with those of 1:1 sex/age-matched cancer-free healthy individuals. RESULTS: Fifty patients (40 radical nephroureterectomy, 7 ureterectomy, and 3 ureteroscopy) with a median (IQR) age of 72 (64-79) years were included. Bladder CARE Index results were positive in 47, high risk in 1, and negative in 2 patients. A significant correlation was found between Bladder CARE Index values and tumor size. Urine cytology was available for 35 patients, of whom 22 (63%) results were false-negative. Upper tract urothelial carcinoma patients had significantly higher Bladder CARE Index values compared to the controls (mean 189.3 vs 1.6, P < .001). The sensitivity, specificity, positive predictive value, and negative predictive value of the Bladder CARE test for detecting upper tract urothelial carcinoma were 96%, 88%, 89%, and 96%, respectively.Conclusions:Bladder CARE is an accurate urine-based epigenetic test for the diagnosis of upper tract urothelial carcinoma, with much higher sensitivity than standard urine cytology.

Robotic Simultaneous Repair of Rectovesical Fistula With Vesicourethral Anastomotic Stricture after Radical Prostatectomy: Step-by-Step Technique and Outcomes.

OBJECTIVE: To report our experience and outcomes using a novel robotic technique for the simultaneous repair of rectovesical fistula (RVF) with vesicourethral anastomotic stricture (VUAS) after radical prostatectomy (RP). METHODS: Between 2019 and 2021, four consecutive patients who underwent robotic-assisted simultaneous repair of RVF with concurrent VUAS after RP were retrospectively reviewed. Baseline characteristics and perioperative outcomes were examined and reported. Complications were graded using the modified Clavien-Dindo classification system and the European Association of Urology Complications Panel Assessment and Recommendations. RESULTS: Four cases with a median age of 68.5 (63.3-72.3) years were treated. Interposition omentum flaps were used in all our cases. One case had perineal urethral mobilization to reach healthy urethral margins and tension-free vesicourethral anastomosis. Surgeries were uneventful, with no intraoperative complications reported. Median operative time, estimated blood loss, and length of hospital stay were 370 (291.3-453) minutes, 255 (175-262.5) mL, and 2.5 (2-3) days, respectively. Median Jackson-Pratt drains, Double-J stents and Foley catheter removal days were 6 (6-10), 38 (32-43), and 30 (27-41) days, respectively. No postoperative complications were reported. The median follow-up time was 16.25 (12-26) months, and no fistula recurrence was shown. CONCLUSION: Robotic-assisted laparoscopic repair could represent an effective approach for the simultaneous repair of RVF with concomitant VUAS. More studies and management standardization are needed to assess the role of the robotic platform in the simultaneous repair of RVF with VUAS after radical prostatectomy.

Obturator Nerve Injury in Robotic Pelvic Surgery: Scenarios and Management Strategies.

BACKGROUND: Obturator nerve injury (ONI) is an uncommon complication of pelvic surgery, usually reported in 0.2-5.7% of cases undergoing surgical treatment of urological and gynecological malignancies involving pelvic lymph node dissection (PLND). OBJECTIVE: To describe how an ONI may occur during robotic pelvic surgery and the corresponding management strategies. DESIGN, SETTING, AND PARTICIPANTS: We retrospectively analyzed video content on intraoperative ONI provided by robotic surgeons from high-volume centers. SURGICAL PROCEDURE: ONI was identified during PLND and managed according to the type of nerve injury. RESULTS AND LIMITATIONS: The management approach varies with the type of injury. Crush injury frequently occurs at an advanced stage of PLND. For a crush injury to the obturator nerve caused by a clip, management only requires its safe removal. Three situations can occur if the nerve is transected: (1) transection with feasible approximation and tension-free nerve anastomosis; (2) transection with challenging approximation requiring certain strategies for proper nerve anastomosis; and (3) transection with a hidden proximal nerve ending that may initially appear intact, but is clearly injured when revealed by further dissection. Each case has different management strategies with a common aim of prompt repair of the anatomic disruption to restore proper nerve conduction. CONCLUSIONS: ONI is a preventable complication that requires proper identification of the anatomy and high-risk areas when performing pelvic lymph node dissection. Prompt intraoperative recognition and repair using the management strategies described offer patients the best chance of recovery without sequelae. PATIENT SUMMARY: We describe the different ways in which the obturator nerve in the pelvic area can be damaged during urological or gynecological surgeries. This is a preventable complication and we describe how it can be avoided and different management options, depending on the type of nerve injury.

Superior Mesenteric Artery Injury during Robotic Radical Nephrectomy: Scenarios and Management Strategies.

Injury to the superior mesenteric artery (SMA) is a rare, underreported, and potentially devastating complication. This study aims to propose a systematic workup to describe how to prevent and manage SMA injury in a standardized stepwise manner. Three different instances of intraoperative injury to the SMA are described in an accompanying video. All three occurred when the SMA was misidentified as the left renal artery during left robotic radical nephrectomy. In the first case, the SMA was mistakenly identified as the renal artery, but after further dissection, the real renal artery was identified and SMA injury was prevented. In the second case, the SMA was clipped and the real left renal artery was subsequently identified, requiring clip removal. In the third case, the SMA was clipped and completely transected, requiring prompt repair by vascular surgery with a successful outcome. This study aims to propose a systematic workup to describe how to prevent and manage SMA injury in a standardized stepwise manner. The proper anatomic recognition of the SMA may prevent its injury. Intraoperative SMA injury should be promptly identified and repaired to avoid its devastating consequences.

Assessment and Reporting of Perioperative Adverse Events and Complications in Patients Undergoing Inguinal Lymphadenectomy for Melanoma, Vulvar Cancer, and Penile Cancer: A Systematic Review and Meta-analysis.

BACKGROUND: Inguinal lymph node dissection (ILND) plays a crucial role in the oncological management of patients with melanoma, penile, and vulvar cancer. This study aims to systematically evaluate perioperative adverse events (AEs) in patients undergoing ILND and its reporting. METHODS: A systematic review was conducted according to PRISMA. PubMed, MEDLINE, Scopus, and Embase were queried to identify studies discussing perioperative AEs in patients with melanoma, penile, and vulvar cancer following ILND. RESULTS: Our search generated 3.469 publications, with 296 studies meeting the inclusion criteria. Details of 14.421 patients were analyzed. Of these studies, 58 (19.5%) described intraoperative AEs (iAEs) as an outcome of interest. Overall, 68 (2.9%) patients reported at least one iAE. Postoperative AEs were reported in 278 studies, combining data on 10.898 patients. Overall, 5.748 (52.7%) patients documented ≥1 postoperative AEs. The most reported ILND-related AEs were lymphatic AEs, with a total of 4.055 (38.8%) events. The pooled meta-analysis confirmed that high BMI (RR 1.09; p = 0.006), ≥1 comorbidities (RR 1.79; p = 0.01), and diabetes (RR 1.81; p = < 0.00001) are independent predictors for any AEs after ILND. When assessing the quality of the AEs reporting, we found 25% of studies reported at least 50% of the required criteria. CONCLUSION: ILND performed in melanoma, penile, and vulvar cancer patients is a morbid procedure. The quality of the AEs reporting is suboptimal. A more standardized AEs reporting system is needed to produce comparable data across studies for furthering the development of strategies to decrease AEs.
