Ileal conduit-vaginal fistulas are a rare but challenging complication of urinary diversion. Here we identify risk factors and summarize the workup and conservative management strategies for this complication. We present two cases of elderly women with remote history of cancer who presented with persistent urinary leakage from the vagina several years after ileal conduit creation. Fistulas may be identified using dye or imaging with a loopogram and looposcopy. Correction of obstruction such as stomal stenosis or urinary diversion should be pursued to relieve pressure off the conduit. Minimally invasive management such as fulguration can result temporary relief; however, the recurrence rate is high.

Background: Within component therapy of massive transfusion protocol (MTP) in trauma, thawed plasma is particularly susceptible to expiring without use given its short 5-day shelf life. Optimizing the number of thawed products without compromising safety is important for hospital resource management. The goal is to examine thawed plasma utilization rates in trauma MTP events and optimize the MTP cooler content at our Level I trauma center. Methods: Trauma MTP activations from 01/2019 to 12/2022 were retrospectively reviewed. During the study period, blood products were distributed in a 12:12:1 ratio of packed red blood cells (pRBC): plasma: platelets per cooler, with up to 4 additional units of low-titer, group O whole blood (LTOWB) available. The primary measure was percent return of unused, thawed plasma. Results: There were 367 trauma MTP activations with amedian (IQR) activation call-to-first cooler delivery time of 8 (6-10) minutes. 73.0% of thawed plasma was returned to the blood bank unused. In one third of MTP activations, all dispensed plasma was returned. The majority (74.1%) of patients required 6 or fewer units of plasma. In 81.5% of activations, 10 or fewer units of plasma and 10 or fewer units of pRBC were used. Discussion: The majority of trauma MTP requirements may be accommodated with a reduced cooler content of 6 units pRBC, 6 units plasma, and 1 pheresis platelets, buffered by up to 4 units LTOWB (approximates 4 units of pRBC/4 units plasma), in conjunction with a sub-10min cooler delivery time. Follow-up longitudinal studies are needed. [ABSTRACT FROM AUTHOR]

Introduction: The role of robotic surgery in the nonelective setting remains poorly defined. Accessibility, patient acuity, and high turn-over may limit its applicability and utilization. The goal is to characterize the role of robotic cholecystectomy (CCY) in a busy acute care surgery (ACS) practice at a quaternary medical center, and compare surgical outcomes and resource utilization between robotic and laparoscopic CCY. Methods: Adult patients who underwent robotic (Da Vinci Xi) or laparoscopic CCY between 01/2021-12/2022 by an ACS attending within 1 week of admission were included. Primary outcomes included time from admission to surgery, off hour (weekend and 6p-6a) cases, operation time, and hospital costs, to reflect "feasibility" of robotic compared to laparoscopic CCY. Secondary outcomes encompassed surgery-related outcomes and complications. Results: The proportion of robotic CCY increased from 5% to 32% within 2 years. In total 361 laparoscopic and 89 robotic CCY were performed. Demographics and gallbladder disease severity were similar. Feasibility measures--operation time, case start time, time from admission to surgery, proportion of off-hour cases, and cost--were comparable between robotic and laparoscopic CCY. There were no differences in surgical complications, common bile duct injury, readmission, or mortality. Conversion to open surgery occurred more often in laparoscopic cases (5% vs 0%, P = .02, OR = 1.05). Discussion: Robotic CCY is associated with fewer open conversions and otherwise similar outcomes compared to laparoscopic CCY in the non-elective setting. Incorporation of robotic CCY in a busy ACS practice model is feasible with available resources. [ABSTRACT FROM AUTHOR]

Introduction: Small bowel obstruction (SBO) is a common cause of hospital admission leading to resource utilization. The majority of these patients require non-operative management (NOM) which can lead to increased length of stay (LOS), readmissions, resource utilization, and throughput delays. Early surgical consultation (SC) for SBO may improve efficiency and outcomes. Methods: We implemented an institution-wide intervention (INT) to encourage early SC (<1 day of diagnosis) for SBO patients in July 2022. A retrospective analysis was performed on all patients with SBO requiring NOM from January 2021 to June 2023, categorized into pre- and post-INT groups. The primary outcome was the number of SC's and secondary outcomes were early SC (<1 day of diagnosis), utilization of SBFT, LOS, 30-day readmission, and costs of admission. Results: A total of 670 patients were included, 438 in the pre-INT and 232 in the post-INT group. Overall, SBFT utilization was significantly higher in cases with SC (17.2% vs 41.4%, P < .001). Post-INT patients were more likely to receive SC (94.0% vs 83.3%, P < .001) and increased SBFT utilization (47.0% vs 33.6%, P = .001). Additionally, early SC improved significantly in the post-INT group (74.3% vs 65.7%, P = .03). There was no difference in LOS between groups (4.0 vs 3.8 days, P = .48). There was a trend toward decreased readmission rates in the INT group at 30 days (7.3% vs 11.0%, P = .13) and reduced direct costs in the INT group (US$/admission = 8467 vs 8708, P = .1). Conclusion: Hospital-wide interventions to increase early surgical involvement proved effective by improving early SC, increased SBFT utilization, and showed a trend towards decreased readmission rates and direct costs.

Purpose: Our clinical understanding of the relationship between 3D bone morphology and knee osteoarthritis, as well as our ability to investigate potential causative factors of osteoarthritis, has been hampered by the time‐intensive nature of manually segmenting bone from MR images. Thus, we aim to develop and validate a fully automated deep learning framework for segmenting the patella and distal femur cortex, in both adults and actively growing adolescents. Methods: Data from 93 subjects, obtained from on institutional review board–approved protocol, formed the study database. 3D sagittal gradient recalled echo and gradient recalled echo with fat saturation images and manual models of the outer cortex were available for 86 femurs and 90 patellae. A deep‐learning–based 2D holistically nested network (HNN) architecture was developed to automatically segment the patella and distal femur using both single (sagittal, uniplanar) and 3 cardinal plane (triplanar) methodologies. Errors in the surface‐to‐surface distances and the Dice coefficient were the primary measures used to quantitatively evaluate segmentation accuracy using a 9‐fold cross‐validation. Results: Average absolute errors for segmenting both the patella and femur were 0.33 mm. The Dice coefficients were 97% and 94% for the femur and patella. The uniplanar, relative to the triplanar, methodology produced slightly superior segmentation. Neither the presence of active growth plates nor pathology influenced segmentation accuracy. Conclusion: The proposed HNN with multi‐feature architecture provides a fully automatic technique capable of delineating the often indistinct interfaces between the bone and other joint structures with an accuracy better than nearly all other techniques presented previously, even when active growth plates are present.

Background: Timing of venous thromboembolism chemoprophylaxis (VTEPPx) in traumatic brain injury (TBI) is complex given concerns for potential worsening of hemorrhage. While timing of VTEPPx for TBI patients is known to vary at the patient level, to our knowledge, variation at the hospital level and correlation with quality metrics have not been quantified in a cohort of nonneurosurgical patients., Methods: This was a retrospective cohort study of the Trauma Quality Improvement database from 2018 to 2021. The primary outcome was variation in VTEPPx timing. This was ascertained by empirical Bayesian methodology using multilevel mixed-effects logistic regression. Secondary outcomes included the association of risk-adjusted VTEPPx timing and hospital characteristics such as volume and risk-adjusted mortality, which was assessed through Pearson's correlation coefficient (r). Risk-adjusted mortality was similarly calculated using multilevel mixed-effects modeling., Results: Of 132,028 patients included in the current study, 38.7% received care at centers in the earliest quartile of VTEPPx timing, classified as Early (others labeled Delayed). Patients receiving care at Early centers presented with severe TBI at a similar rate to Delayed (17.4% vs. 19.0%; absolute standardized mean difference, 0.04). Early center patients more commonly received unfractionated heparin as opposed to low-molecular-weight heparin compared with Delayed (40.5% vs. 27.6%; absolute standardized mean difference, 0.28). At the center level, 12% of observed variation in VTEPPx was attributable to differential hospital practices. Overall trauma volume (r = -0.22, p < 0.001) and TBI volume (r = -0.19, p < 0.001) were inversely associated with risk-adjusted VTEPPx timing. In addition, centers initiating VTEPPx earlier had lower overall (r = 0.17, p < 0.001) and TBI-related mortality (r = 0.17, p < 0.001)., Conclusion: There is significant center-level variation in timing of VTEPPx among TBI patients. Earlier VTEPPx was associated with improved center outcomes overall and among TBI patients, supporting usage of VTEPPx timing as a holistic measure of quality., Level of Evidence: Prognostic and Epidemiological; Level III., (Copyright © 2024 Wolters Kluwer Health, Inc.
