Outcome prediction in bariatric surgery through video-based assessment.

INTRODUCTION: The relationship between intraoperative surgical performance scores and patient outcomes has not been demonstrated at a single-case level. The GEARS score is a Likert-based scale that quantifies robotic surgical proficiency in 5 domains. Given that even highly skilled surgeons can have variability in their skill among their cases, we hypothesized that at a patient level, higher surgical skill as determined by the GEARS score will predict individual patient outcomes. METHODS: Patients undergoing robotic sleeve gastrectomy between July 2018 and January 2021 at a single-health care system were captured in a prospective database. Bivariate Pearson's correlation was used to compare continuous variables, one-way ANOVA for categorical variables compared with a continuous variable, and chi-square for two categorical variables. Significant variables in the univariable screen were included in a multivariable linear regression model. Two-tailed p-value < 0.05 was considered significant. RESULTS: Of 162 patients included, 9 patients (5.5%) experienced a serious morbidity within 30 days. The average excess weight loss (EWL) was 72 ± 12% at 6 months and 74 ± 15% at 12 months. GEARS score was not significantly correlated with EWL at 6 months (p = 0.349), 12 months (p = 0.468), or serious morbidity (p = 0.848) on unadjusted analysis. After adjusting, total GEARS score was not correlated with serious morbidity (p = 0.914); however, GEARS score did predict EWL at 6 (p < 0.001) and 12 months (p < 0.001). All GEARS subcomponent scores, bimanual dexterity, depth perception, efficiency, force sensitivity, and robotic control were predictive of EWL at 6 months (p < 0.001) and 12 months (p < 0.001) on multivariable analysis. CONCLUSION: For patients undergoing sleeve gastrectomy, surgical skill as assessed by the GEARS score was correlated with EWL, suggesting that better performance of a sleeve gastrectomy can result in improved postoperative weight loss.

Systematic review of interventions that improve provider compliance to imaging guidelines for prostate cancer.

INTRODUCTION: Radiographic staging with bone scan or computed tomography is not indicated for men with low-risk prostate cancer. Physician compliance with these imaging recommendations has been widely variable, leading to inappropriate testing and increased costs. The purpose of this systematic review was to identify and learn from interventions associated with improved physician compliance to imaging guidelines for prostate cancer staging. METHODS: This systematic review followed Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. PubMed was searched through January 2022 for the following medical subject headings (MeSH) terms: ('practice patterns, physicians' or 'guideline adherence' or 'unnecessary procedures' or 'quality improvement') and ('prostatic neoplasms/diagnostic imaging'). Inclusion required discussion of an intervention for physician compliance to prostate cancer imaging guidelines and specific data describing associated outcomes. Publications focused on other malignancies or without this intervention, evaluation, or data were excluded. RESULTS: Of 82 papers screened, only five met inclusion criteria - representing 12 802 patients. Each focused on reducing unnecessary imaging and demonstrated statistically significant post-intervention improvement of physician compliance to imaging guidelines for staging prostate cancer. Four were multidimensional, with education, clinical champions, and performance feedback. One used the unidimensional intervention of an electronic medical record (EMR)-based clinical reminder order check (CROC). No studies used randomization or a control group. CONCLUSIONS: Post-intervention improvement in physician compliance to imaging guidelines for staging prostate cancer has been associated with EMR-based CROC and combination interventions using clinical champions, education, and feedback. This has been observed at individual institutions and larger organizations spanning a region or state.

Systematic review of telemedicine in pediatric urology.

INTRODUCTION: Telemedicine has bridged the distance gap between patients and pediatric urologists for over a decade, yet many pediatric urologists have not embraced it as a major part of their practice. The purpose of this systematic review is to evaluate and clarify the optimal role of telemedicine in pediatric urology, as well as the benefits, barriers, risks, and other important considerations that must be accounted for in its optimal adoption. METHODS: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, this systematic review utilized Medical Subject Headings (MeSH) to search PubMed through April 29, 2021 as follows: (Humans [MeSH]) AND ((Child [MeSH]) OR (Infant [MeSH])) AND ((Remote Consultation [MAJR]) OR (Telemedicine [MAJR]) OR (Videoconferencing [MAJR]) OR (Health Services Accessibility [MAJR])) AND ((Urology [MAJR]) OR (Postoperative Care [MAJR]) OR (Urologic Surgical Procedures [MAJR])). 73 resulting articles, plus 21 from manual searches (e.g. papers too recent to have MeSH terms), were screened. 17 met inclusion criteria by discussing telemedicine in context of pediatric urology in a full manuscript. Non-complete manuscripts and papers not specifically considering pediatric urology, or in which telemedicine was not a major focus, were excluded. RESULTS: 17 papers met inclusion criteria. Varied approaches to the topic included surveys, controlled studies, retrospective studies, and descriptive opinion pieces. Quality of evidence varied, representing at least 1851 virtual encounters, 409 in-person encounters, and 68 clinician opinions. Four papers included a comparison or control group, and none utilized randomization. All 17 papers support expanded application of telemedicine in pediatric urology with varied evidence that telemedicine improves patient access to pediatric urologic care, satisfies both patient families and clinicians, is safe, provides equivalent outcomes, and is practicable. CONCLUSIONS: Implementation of telemedicine in pediatric urology should be expanded as it can practicably and safely improve patient access to pediatric urologic care, satisfy both patient families and clinicians, and maintain outcomes.

Neonatal multicystic dysplastic kidney with mass effect: A systematic review.

INTRODUCTION: Multicystic Dysplastic Kidney (MCDK) is a common cause of palpable abdominal mass in a neonate, yet reports are few of resultant life-threatening extrinsic compression. This systematic review is the first to review all known neonatal MCDK cases complicated by external compression due to mass effect. Our aim is to foster communication about these unusual cases to inform management of future comparable cases. METHODS: This systematic review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Medical Subject Headings (MeSH) were used to search PubMed through June 8, 2021 as follows: ((((Polycystic Kidney Diseases/complications [MeSH Terms]) OR (Multicystic Dysplastic Kidney/complications [MeSH Terms])) AND (Humans [MeSH Terms]) AND (Infant, Newborn [MeSH Terms]) AND (Case Reports [Publication Type]) AND (("multicystic dysplastic kidney") OR ("multicystic kidney")))) OR ((unusual respiratory distress in newborn [Title]) AND (kidney)) OR (large MCDK). Resulting papers were screened and included if they reported neonatal MCDK complicated by external compression by mass effect. Excluded papers lacked an MCDK diagnosis, a neonatal patient, or clear indication of mass effect. Salient data was extracted from each case for comparison. RESULTS: Of 51 papers screened, seven met inclusion criteria, presenting eight neonatal MCDK patients exhibiting varied combinations of symptoms secondary to external compression, including respiratory distress, gastrointestinal obstruction, and contralateral ureteral obstruction. All eight cases, ultimately managed with neonatal nephrectomy, had positive outcomes. Unreported and undiagnosed cases are not included in this review, making it susceptible to publication bias. CONCLUSIONS: Large neonatal MCDK is typically managed conservatively, however it can be complicated by external compression due to mass effect. In this scenario, nephrectomy is a reasonable and definitive treatment. Less invasive management options may exist, e.g., aspiration with sclerotherapy. Communication about exceptional cases like these should be encouraged even when outcomes are poor.

Multicystic Dysplastic Kidney With Mass Effect in a Neonate Treated With Nephrectomy: Case Report.

Multicystic Dysplastic Kidney is a developmental disease that results in a lobulated kidney of noncommunicating cysts and abnormal parenchymal tissue. Dysplastic kidneys are usually benign and often involute over time with conservative management. The second most common cause of palpable abdominal mass in a neonate, Multicystic Dysplastic Kidney can cause respiratory distress secondary to extrinsic compression. However, such cases are sparse. Here we present the case of an otherwise healthy term newborn with an exceptionally large MCDK requiring CPAP support and intubation. His respiratory distress improved immediately after nephrectomy. Communication about cases like this will inform management of future comparable cases.

Polymicrobial abscess following ovariectomy in a mouse.

BACKGROUND: Ovariectomy is a common procedure in laboratory rodents used to create a post-menopausal state. Complications including post-surgical abscess are rarely reported, but merit consideration for the health and safety of experimental animals. CASE PRESENTATION: A female C57/black6 mouse was ovariectomized as part of a cohort study. At Day 14 post-surgery, she developed a visible swelling on the right side, which 7 days later increased in size over 24 h, leading to euthanasia of the animal. Gross pathology was consistent with abscess. A core of necrotic tissue was present in the uterine horn. Abscess fluid and affected tissue were collected for Gram stain and bacteriological culture. The abscess core and fluid yielded three distinct types of bacterial colonies identified by 16S ribosomal RNA sequencing as Streptococcus acidominimus, Pasteurella caecimuris, and a novel species in the genus Gemella. CONCLUSIONS: This is the first report of polymicrobial abscess in a rodent as a complication of ovariectomy, and the first description of a novel Gemella species for which we have proposed the epithet Gemella muriseptica. This presentation represents a potential complication of ovariectomy in laboratory animals.
