Quantifying Perioperative Risks for Antireflux and Hiatus Hernia Surgery: A Multicenter Cohort Study of 4301 Patients.

OBJECTIVE: Using a comprehensive Australian cohort, we quantified the incidence and determined the independent predictors of intraoperative and postoperative complications associated with antireflux and hiatus hernia surgeries. In addition, we performed an in-depth analysis to understand the complication profiles associated with each independent risk factor. BACKGROUND: Predicting perioperative risks for fundoplication and hiatus hernia repair will inform treatment decision-making, hospital resource allocation, and benchmarking. However, available risk calculators do not account for hernia anatomy or technical aspects of surgery in estimating perioperative risk. METHODS: Retrospective analysis of all elective antireflux and hiatus hernia surgeries in 36 Australian hospitals over 10 years. Hierarchical multivariate logistic regression analyses were performed to determine the independent predictors of intraoperative and postoperative complications accounting for patient, surgical, anatomic, and perioperative factors. RESULTS: A total of 4301 surgeries were analyzed. Of these, 1569 (36.5%) were large/giant hernias and 292 (6.8%) were revisional procedures. The incidence rates of intraoperative and postoperative complications were 12.6% and 13.3%, respectively. The Charlson Comorbidity Index, hernia size, revisional surgery, and baseline anticoagulant usage independently predicted both intraoperative and postoperative complications. These risk factors were associated with their own complication profiles. Finally, using risk matrices, we visualized the cumulative impact of these 4 risk factors on the development of intraoperative, overall postoperative, and major postoperative complications. CONCLUSIONS: This study has improved our understanding of perioperative morbidity associated with antireflux and hiatus hernia surgery. Our findings group patients along a spectrum of perioperative risks that inform care at an individual and institutional level.

A Practical Approach to Interpreting Circulating Tumor DNA in the Management of Gastrointestinal Cancers.

BACKGROUND: There is accumulating evidence supporting the clinical use of circulating tumor DNA (ctDNA) in solid tumors, especially in different types of gastrointestinal cancer. As such, appraisal of the current and potential clinical utility of ctDNA is needed to guide clinicians in decision-making to facilitate its general applicability. CONTENT: In this review, we firstly discuss considerations surrounding specimen collection, processing, storage, and analysis, which affect reporting and interpretation of results. Secondly, we evaluate a selection of studies on colorectal, esophago-gastric, and pancreatic cancer to determine the level of evidence for the use of ctDNA in disease screening, detection of molecular residual disease (MRD) and disease recurrence during surveillance, assessment of therapy response, and guiding targeted therapy. Lastly, we highlight current limitations in the clinical utility of ctDNA and future directions. SUMMARY: Current evidence of ctDNA in gastrointestinal cancer is promising but varies depending on its specific clinical role and cancer type. Larger prospective trials are needed to validate different aspects of ctDNA clinical utility, and standardization of collection protocols, analytical assays, and reporting guidelines should be considered to facilitate its wider applicability.

Early Elbow Flexion Contracture Predicts Shoulder Contracture in Infants with Brachial Plexus Birth Injury.

OBJECTIVE: To determine if children who present with an elbow flexion contracture (EFC) from brachial plexus birth injury (BPBI) are more likely to develop shoulder contracture and undergo surgical treatment. STUDY DESIGN: Retrospective review of children <2 years of age with BPBI who presented to a single children's hospital from 1993 to 2020. Age, elbow and shoulder range of motion (ROM), imaging measurements, and surgical treatment and outcome were analyzed. Patients with an EFC of ≥10° were included in the study sample. Data from 2445 clinical evaluations (1190 patients) were assessed. The final study cohort included 72 EFC cases matched with 230 non-EFC controls. Three patients lacked sufficient follow-up data. RESULTS: There were 299 included patients who showed no differences between study and control groups with respect to age, sex, race, ethnicity, or functional score. Patients with EFC had 12° less shoulder range of motion (95% CI, 5°-20°; P < .001) and had 2.5 times the odds of shoulder contracture (OR, 2.5; 95% CI, 1.3-4.7; P = .006). For each additional 5° of EFC, the odds of shoulder contracture increased by 50% (OR, 1.5; 95% CI, 1.2-1.8; P < .001) and odds of shoulder procedure increased by 62% (OR, 1.62; 95% CI, 1.04-2.53; P = .03). Sensitivity of EFC for predicting shoulder contracture was 49% and specificity was 82%. CONCLUSIONS: In patients with BPBI <2 years of age, presence of EFC can be used as a screening tool in identifying shoulder contractures that may otherwise be difficult to assess. Prompt referral should be arranged for evaluation at a BPBI specialty clinic, because delayed presentation risks worsening shoulder contracture and potentially more complicated surgery.

Vagal sparing gastrectomy: A systematic review and meta-analysis.

Radical gastrectomy is associated with significant functional complications. In appropriate patients may be amenable to less invasive resection aimed at preserving the vagal trunks. The aim of this systematic review and meta-analysis is to assess the functional consequences and oncological safety of vagal sparing gastrectomy (VSG) compared to conventional non-vagal sparing gastrectomy (CG). A systematic review of four databases was undertaken for studies published between 1/11990 and 15/122021, comparing patients who underwent VSG to CG. We meta-analysed the following outcomes: operative time, blood loss, nodal yield, days to flatus, body weight changes, as well as the incidence of post-operative cholelithiasis, diarrhoea, delayed gastric emptying, and dumping syndrome. Thirty studies were included in the meta-analysis with a selection of studies qualitatively analysed. VSG was associated with a lower rate of cholelithiasis (OR 0.25, 95% CI 0.15-0.41, p<0.010) and early dumping syndrome (OR 0.42, 95% CI 0.21 - 0.86; p=0.02), less blood loss (MD -51 ml, 95% CI -89.11 to -12.81 ml, p=0.009), less long term weight loss (MD 2.03%, 95% CI 0.31-3.76%, p=0.02) and a faster time to flatus (MD -0.42 days, 95% CI -0.48 - 0.36, p<0.001). There was no significant difference in nodal harvest, overall survival, and all other endpoints. VSG significantly reduces the incidence of post-operative cholelithiasis and dumping syndrome, decreases weight loss and facilitates an earlier return of gut motility. Although technically more challenging, VSG should be considered for prophylactic surgery.

Telehealth Potential in Pediatric Orthopaedics and Sports Medicine Care is Comparable to In-Person Care But Disparities Remain.

BACKGROUND: Understanding the challenges and potential of telehealth visits (THVs) in a large population can inform future practice and policy discussion for pediatric orthopaedic and sports medicine (OSM) care. We comprehensively assess telehealth challenges and potential in a large pediatric OSM population based on access, visit completion, patient satisfaction, and technological challenges. METHODS: Demographics, address, insurance, visit information, patient feedback, experience with video visits, and technical challenges of all 2019 to 2020 visits at our hospital were assessed (3,278,006 visits). We evaluated the differences in rate of telehealth utilization, rate of patient adherence, disparities in care access and patient satisfaction, and technological issues. RESULTS: Compared with in-person prepandemic visits, THVs had lower ratios of non-White patients (by 5.8%; P <0.001), Hispanic patients (by 2.8%; P <0.001) and patients with public insurance (by 1.8%; P <0.001), and a higher mean distance between the patient's residence and clinic (by 18.8 miles; P <0.001). There were minimal differences in median household income (average $2297 less in THV; P <0.001) and social vulnerability index (average 0.01 points lower in THV; P <0.001) between groups. THVs had comparable patient satisfaction to in-person visits. Non-White patients, Hispanics, and those with public insurance had lower ratings for both in-person visits and THVs and had more technical difficulties during their THV. CONCLUSIONS: Telehealth is a viable method of care for a range of pediatric OSM conditions, providing a similar quality of care as in-person visits with a greater geographic reach. However, in its current format, reduced disparities were not observed in pediatric OSM THVs. LEVEL OF EVIDENCE: Level III.

Pediatric and Adolescent Distal Radius Fractures: Current Concepts and Treatment Recommendations.

Distal radius fractures are the most common skeletal injuries requiring intervention in children. These injuries are classified by fracture pattern, location, displacement, and angulation. While each unique fracture pattern warrants slightly modified treatment plans and follow-up, the goals of treatment remain constant. Successful outcomes depend on restoration of motion and function, and attaining acceptable sagittal and coronal alignment is a necessary first step. For displaced fractures, closed reduction is often necessary to restore alignment; well-molded cast application is important to maintain fracture alignment. Fractures with bayonet apposition, if well aligned, may not need formal reduction in some patients. Special attention should be paid to the physis-not only for physeal-involving fractures but also for all distal radius fractures-given that the proximity to the physis and amount of remaining skeletal growth help guide treatment decisions. Casting technique is essential in optimizing the best chance in maintaining fracture reduction. Surgical intervention may be indicated for a subset of fractures when acceptable alignment is not achieved or is lost at subsequent follow-up. Even among experts in the field, there is little consensus as to the optimal treatment of displaced metaphyseal fractures, illustrating the need for prospective, randomized studies to establish best practices.

Occipital condyle fracture in the pediatric population: A management algorithm and systematic review.

Purpose: This study aims to develop an accessible stepwise management algorithm for pediatric presentations of occipital condyle fractures (OCFs) based on a systematic review of the published literature regarding diagnostic evaluation, treatment, and outcomes. Methods: A systematic review of the literature was conducted on PubMed to locate English language studies reporting on the management of pediatric OCFs. Data extraction of clinical presentation, management strategies, imaging, and treatment outcome was performed. Results: A total of 15 studies reporting on 38 patients aged 18 years and younger presenting with OCFs were identified. Loss of consciousness (LOC), depressed level of consciousness, neck pain, decreased neck range of motion (ROM), and cranial nerve injury were the most common presenting symptoms. Diagnostic imaging included radiographs, computed tomography (CT) scans, magnetic resonance imaging (MRI), and functional radiographs to assess cervical stability. Treatment options varied and included soft collar, hard collar, and halo vest. All studies resulted in a complete healing of the OCF, with resolution of associated pain. Conclusion: The proposed treatment algorithm suggests a framework for the management of pediatric OCFs based on the available evidence (levels of evidence: 3, 4). This review of the literature indicated that a stepwise approach should be utilized in the management of isolated pediatric OCFs.

Peritoneal Tumor DNA as a Prognostic Biomarker in Gastric Cancer: A Systematic Review and Meta-Analysis.

PURPOSE: Gastric cancers commonly spread to the peritoneum. Its presence significantly alters patient prognosis and treatment-intent; however, current methods of peritoneal staging are inaccurate. Peritoneal tumor DNA (ptDNA) is tumor-derived DNA detectable in peritoneal lavage fluid. ptDNA positivity may indicate peritoneal micrometastasis and may be more sensitive than cytology in staging the peritoneum. In this meta-analysis, we evaluated the prognostic potential of ptDNA in gastric cancer. METHODS: PubMed, Embase, Scopus, and Web of Science databases were searched using PRISMA guidelines. Studies published between January 1, 1990, and April 30, 2023, containing quantitative data relating to ptDNA in gastric cancer were meta-analyzed. RESULTS: Six studies were analyzed. Of the total 757 patients with gastric adenocarcinoma, 318 (42.0%) were stage I, 311 (41.0%) were stage II/III, 116 (15.3%) were stage IV, and 22 (2.9%) were undetermined. Overall, ptDNA detected cytology-positive cases with a sensitivity and specificity of 85.2% (95% CI, 66.5 to 100.0) and 91.5% (95% CI, 86.5 to 96.6), respectively. Additionally, ptDNA was detected in 54 (8.5%) of 634 cytology-negative patients. The presence of ptDNA negatively correlated with pathological stage I (relative risk [RR], 0.29 [95% CI, 0.13 to 0.66]) and positively correlated with pathological stage IV (RR, 8.61 [95% CI, 1.86 to 39.89]) disease. Importantly, ptDNA positivity predicted an increased risk of peritoneal-specific metastasis (RR, 13.81 [95% CI, 8.11 to 23.53]) and reduced 3-year progression-free (RR, 5.37 [95% CI, 1.39 to 20.74]) and overall (hazard ratio, 4.13 [95% CI, 1.51 to 11.32]) survival. CONCLUSION: ptDNA carries valuable prognostic information and can detect peritoneal micrometastases in patients with gastric cancer. Its clinical utility in peritoneal staging for gastric cancer deserves further investigation.

Cost burden following esophagectomy: A single centre observational study.

BACKGROUND: Cost analyses of patients undergoing esophagectomy is valuable for identifying modifiable expenditure drivers to target and curtail costs while improving the quality of care. We aimed to define the cost-complication relationship after esophagectomy and delineate the incremental contributions to costs. AIM: To assess the relationship between the hospital costs and potential cost drivers post esophagectomy and investigate the relationship between the cost-driving variables (predicting variables) and hospital costs (dependent variable). METHODS: In this retrospective single center study, the severity of complications was graded using the Clavien-Dindo (CD) classification system. Key esophagectomy complications were categorized and defined according to consensus guidelines. Raw costing data included the in-hospital costs of the index admission and any unplanned admission within 30 postoperative days. We used correlation analysis to assess the relationship between key clinical variables and hospital costs (in United States dollars) to identify cost drivers. A mediation model was used to investigate the relationship between these variables and hospital costs. RESULTS: A total of 110 patients underwent primary esophageal resection. The median admission cost was $47822.7 (interquartile range: 35670.2-68214.0). The total effects on costs were $13593.9 (95%CI: 10187.1-17000.8, P < 0.001) for each increase in CD severity grade, $4781 (95%CI: 3772.7-5789.3, P < 0.001) for each increase in the number of complications, and $42552.2 (95%CI: 8309-76795.4, P = 0.015) if a key esophagectomy complication developed. Key esophagectomy complications drove the costs directly by $11415.7 (95%CI: 992.5-21838.9, P = 0.032). CONCLUSION: The severity and number of complications, and the development of key esophagectomy complications significantly contributed to total hospital costs. Continuous institutional initiatives and strategies are needed to enhance patient outcomes and minimize costs.

The Troubling Rise of Scurvy: A Review and National Analysis of Incidence, Associated Risk Factors, and Clinical Manifestations.

INTRODUCTION: In the era of modern medicine, scurvy has been thought of as a rare disease of ancient times because of improved emphasis on diet and nutrition; however, isolated case reports are plentiful. This investigation presents a comprehensive review of scurvy, including an analysis on its rising incidence, with specific focus on its orthopaedic manifestations and commonly associated diagnoses. METHODS: This comprehensive review includes a retrospective analysis of 19,413,465 pediatric patients in the National Inpatient Sample database from 2016 through 2020. Patients with scurvy were identified by the ICD-10 code, and an estimated incidence of scurvy in the inpatient pediatric population was calculated. Concurrent diagnoses, musculoskeletal reports, and demographic variables were collected from patient records. Comparisons were made using analysis of variance or chi-square with Kendall tau, where appropriate. RESULTS: The incidence of scurvy increased over the study period, from 8.2 per 100,000 in 2016 to 26.7 per 100,000 in 2020. Patients with scurvy were more likely to be younger (P < 0.001), male (P = 0.010), in the lowest income quartile (P = 0.013), and obese (P < 0.001). A majority (64.2%) had a concomitant diagnosis of autism spectrum disorder. Common presenting musculoskeletal reports included difficulty walking, knee pain, and lower limb deformity. Burden of disease of scurvy was markedly greater than that of the average inpatient population, with these patients experiencing greater total charges and longer hospital stays. CONCLUSION: Clinicians should be aware of the increasing incidence of scurvy in modern medicine. In cases of vague musculoskeletal reports without clear etiology, a diagnosis of scurvy should be considered, particularly if risk factors are present. TRIAL REGISTRATION NUMBER: NA.

A Novel Design-Thinking, Hospital Innovation Core Certificate Curriculum for Radiologists and Trainees: Creation, Implementation, and Multiyear Results.

RATIONALE AND OBJECTIVES: Innovation is a crucial skill for physicians and researchers, yet traditional medical education does not provide instruction or experience to cultivate an innovative mindset. This study evaluates the effectiveness of a novel course implemented in an academic radiology department training program over a 5-year period designed to educate future radiologists on the fundamentals of medical innovation. MATERIALS AND METHODS: A pre- and post-course survey and examination were administered to residents who participated in the innovation course (MESH Core) from 2018 to 2022. Respondents were first evaluated on their subjective comfort level, understanding, and beliefs on innovation-related topics using a 5-point Likert-scale survey. Respondents were also administered a 21-question multiple-choice exam to test their objective knowledge of innovation-related topics. RESULTS: Thirty-eight residents participated in the survey (response rate 95%). Resident understanding, comfort and belief regarding innovation-related topics improved significantly (P < .0001) on all nine Likert-scale questions after the course. After the course, a significant majority of residents either agreed or strongly agreed that technological innovation should be a core competency for the residency curriculum, and that a workshop to prototype their ideas would be beneficial. Performance on the course exam showed significant improvement (48% vs 86%, P < .0001). The overall course experience was rated 5 out of 5 by all participants. CONCLUSION: MESH Core demonstrates long-term success in educating future radiologists on the basic concepts of medical technological innovation. Years later, residents used the knowledge and experience gained from MESH Core to successfully pursue their own inventions and innovative projects. This innovation model may serve as an approach for other institutions to implement training in this domain.

Offering nurse care management for opioid use disorder in primary care: Impact on emergency and hospital utilization in a cluster-randomized implementation trial.

BACKGROUND: Patients with opioid use disorder (OUD) have increased emergency and hospital utilization. The PROUD trial showed that implementation of office-based addiction treatment (OBAT) increased OUD medication treatment compared to usual care, but did not decrease acute care utilization in patients with OUD documented pre-randomization (clinicaltrials.gov/study/NCT03407638). This paper reports secondary emergency and hospital utilization outcomes in patients with documented OUD in the PROUD trial. METHODS: This cluster-randomized implementation trial was conducted in 12 clinics from 6 diverse health systems (March 2015-February 2020). Patients who visited trial clinics and had an OUD diagnosis within 3 years pre-randomization were included in primary analyses; secondary analyses added patients with OUD who were new to the clinic or with newly-documented OUD post-randomization. Outcomes included days of emergency care and hospital utilization over 2 years post-randomization. Explanatory outcomes included measures of OUD treatment. Patient-level analyses used mixed-effect regression with clinic-specific random intercepts. RESULTS: Among 1988 patients with documented OUD seen pre-randomization (mean age 49, 53 % female), days of emergency care or hospitalization did not differ between intervention and usual care; OUD treatment also did not differ. In secondary analyses among 1347 patients with OUD post-randomization, there remained no difference in emergency or hospital utilization despite intervention patients receiving 32.2 (95 % CI 4.7, 59.7) more days of OUD treatment relative to usual care. CONCLUSIONS: Implementation of OBAT did not reduce emergency or hospital utilization among patients with OUD, even in the sample with OUD first documented post-randomization in whom the intervention increased treatment.

Posterior Tibiotalar Impingement After Pediatric Ankle Fracture Surgical Fixation: A Case Report.

CASE: A 13-year-old healthy, nearly skeletally mature, female patient presented to an outpatient clinic after sustaining a bimalleolar ankle fracture-dislocation, which was subsequently treated with open reduction and internal fixation and casting. Postoperatively, the patient had significant limitations to ankle range of motion. Imaging revealed posterior tibiotalar impingement. The patient underwent arthroscopic debridement and osteoplasty, and she was able to return to previous levels of activity. CONCLUSIONS: Complications from pediatric ankle fractures are rare, so further diagnostic workup is warranted for patients with persistent pain and limitations.
