Effects of Glucagon-like Peptide-1 Receptor Agonists on Upper Endoscopy in Diabetic and Non-Diabetic Patients.

BACKGROUND AND AIMS: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) promote weight loss by suppressing appetite, enhancing satiety, regulating glucose metabolism and delaying gastric motility. We sought to determine whether GLP-1 RA use could impact sedated medical procedures like esophagogastroduodenoscopy (EGD). METHODS: We conducted a retrospective study on 35,183 patients who underwent EGD between 2019 and 2023, 922 of which were using a GLP-1-RA. Data were collected regarding demographics, diabetes status, retained gastric contents during EGD (RGC), incidence of aborted EGD, and necessity for repeat EGD. RESULTS: GLP-1 RA use was associated with a fourfold increase in the retention of gastric contents (p<0.0001), fourfold higher rates of aborted EGD (p<0.0001), and twice the likelihood of requiring repeat EGD (p=0.0001), even after stratifying for presence of diabetes. CONCLUSIONS: GLP-1 RA use can lead to delayed gastric emptying, affecting EGD adequacy regardless of the presence of diabetes, and may warrant dose adjustment to improve safety and efficacy of these procedures.

The Effect of Surgical Approach on the Outcomes of Same-Day Discharge Outpatient Total Hip Arthroplasty at a Single Ambulatory Surgery Center.

BACKGROUND: Primary total hip arthroplasty (THA) is increasingly being performed in the outpatient setting. However, there is little known regarding the differences in same-day discharge (SDD) rates and complications of operative approach in same-day total hip arthroplasty in the ambulatory surgery center (ASC) setting. METHODS: A retrospective chart review was performed between July 2019 and October 2021 for all patients who underwent primary THA in a single freestanding ASC. Successful SDDs, surgical approaches, lengths of surgery, estimated blood losses (EBL), complications, and readmission events were recorded for each patient. Complications were compared using Pearson Chi-Squares, while EBL and surgery lengths were compared with 1-way analysis of variances (ANOVA) (alpha = 0.5). There were 17 total complications in 326 total hip arthroplasties (5.2%), including direct admissions to the emergency department, 30-day and 90-day readmissions, wound complications, instability, infection, and revision surgery. Among all complications, there were 5 direct admissions, making the successful SDD rate 98.5%. RESULTS: Complications and direct admissions were not associated with approach. The 30-day readmission rates were associated with approach, with no readmissions in the direct anterior approach (DAA) or the antero-lateral approach (AL) cohorts and 3 (4.3%) in the posterior approach (PA) cohort. CONCLUSIONS: In the ASC setting, patients undergoing THA regardless of approach showed no difference in successful SDDs or complications aside from 30-day readmissions. Same-day THA can be safely performed in the DAA, AL, and PA to the hip.

Predicting Positive Margins in Pancreatic Head Adenocarcinoma After Neoadjuvant Therapy: Investigating Disparities in Quality Care Using the National Cancer Database.

BACKGROUND: In pancreatic cancer, surgical resection with neoadjuvant therapy improves survival, but survival relies significantly on the margin status of the resected tissue. This study aimed to develop a model that predicts margin positivity, and then to identify facility-specific factors that influence the observed-to-expected (O/E) ratio for positive margins among facilities. METHODS: This retrospective review analyzed patients in the National Cancer Database (2004-2016) with pancreatic head adenocarcinoma [tumor-node-metastasis (TNM) stage 1 or 2] who received neoadjuvant therapy for a pancreaticoduodenectomy. Logistic regression was used to develop a model that predicts margin positivity. This model then was used to identify outlier facilities with regard to the O/E ratio. Hospital volume was defined as the total number of pancreaticoduodenectomies per year. RESULTS: The study enrolled 4085 patients, and 16.8% of these patients had positive margins. Most of the patients (64%) had a tumor size of 2 to 4 cm, and approximately 51% of the patients did not have positive lymph nodes at resection. A logistic regression model showed that the predictors of positive margins after resection with neoadjuvant therapy were male sex, larger tumor size, and positive lymph nodes. This model was validated to yield a bootstrap-corrected concordance index of 0.632. The study calculated O/E ratios with the model, identifying 12 low- and 17 high O/E-ratio outlier facilities among 401 studied hospitals. The outlier hospitals did not differ in facility type (i.e., academic vs integrated network), but did differ significantly in terms of yearly hospital volume (low outlier of 20.6 vs high outlier of 10.7; p = 0.008). CONCLUSIONS: An association of lower-volume facilities with higher than expected rates of positive margins was found to indicate a disparity in care. This disparity was identified via an O/E ratio as a quality indicator for facilities. Facilities can gauge the efficiency of their own practices by referencing their O/E ratios, and they also can improve their practices by analyzing the framework of low O/E-ratio facilities.

Identifying Outlier Hospitals in Gastric Cancer Lymph Node Yield Using the National Cancer Database.

BACKGROUND: Lymph node (LN) yield is a key quality indicator that is associated with improved staging in surgically resected gastric cancer. The National Comprehensive Cancer Network recommends a yield of ≥15 LNs for proper staging, yet most facilities in the United States fail to achieve this number. The present study aimed to identify factors that could affect LN yield on a facility level and identify outlier hospitals. METHODS: This was a retrospective review of adults (aged ≥18 y) with gastric cancer (Tumor-Node-Metastasis Stages I-III) who underwent gastrectomy. Data were analyzed from the National Cancer Database (2004-2016). Multivariate analysis identified patient and tumor characteristics, whereas an observed-to-expected ratio of identified outlier hospitals. Facility factors were compared between high and low outliers. RESULTS: A total of 26,590 patients were included in this study. Of these patients, only 50.3% had an LN yield ≥15. The multivariate model of patient and tumor characteristics demonstrated a concordance index was 0.684. A total of 1245 facilities were included. There were 198 low outlier LN yield hospitals and 135 high outlier LN yield hospitals (observed-to-expected ratio of 0.42 ± 0.24 versus 1.38 ± 0.19, P < 0.0001). There was a difference in facility type between low and high outliers (P < 0.0001). High LN yield hospitals had a larger surgical volume than low LN yield hospitals (median 8.4 [4.9, 13.5] versus 3.5 [2.4, 5.2]; P < 0.0001). CONCLUSIONS: Nearly half of the population exhibited low compliance to National Comprehensive Cancer Network recommendations. Facility-level disparities exist as high yearly surgical volume and academic facility status distinguished high-performing outlier hospitals.

A 3-Year MBSAQIP propensity-matched analysis of Roux-en-Y gastric bypass with concomitant cholecystectomy: Is the robotic or laparoscopic approach preferred?

BACKGROUND: The primary objective of this study was to compare outcomes of patients undergoing minimally invasive RYGB (MIS/RYGB) versus MIS/RYGB with concomitant Cholecystectomy (CCY). A secondary objective was to compare the outcomes for laparoscopic RYGB (LRYGB) and robotic RYGB (RRYGB) with concomitant CCY. METHODS: Outcomes of 117,939 MIS/RYGB with and without CCY were propensity-matched (Age, Gender, BMI, Comorbidities), 10:1, using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database from 2015-2017. The MIS/RYGB with CCY were then separated into LRYGB and RRYGB cases for comparison. Exclusion criteria included emergency cases, conversions to open, and age less than 18. RESULTS: The operative time and length of stay (LOS) was significantly increased with addition of concomitant CCY. There was no significant difference in readmission, reoperation, intervention, morbidity, or mortality. The RRYGB with CCY approach was associated with a significantly longer operative times compared to the LRYGB with CCY (177 vs. 135 min, p < 0.0001). The laparoscopic and robotic groups demonstrated no significant difference LOS, readmission, reoperation, intervention, morbidity, or mortality rates. CONCLUSIONS: Our study demonstrates that concomitant cholecystectomy increased the operative time and length of stay. However, concomitant CCY was not associated with any increased morbidity. The study demonstrated no significant difference in morbidity between robotic and laparoscopic approach. The robotic approach, however, was associated with a significantly longer operative time compared to the laparoscopic approach. While the indications for CCY remain controversial, concomitant CCY does not convey additional risk regardless of operative approach.

Emergency department overutilization following cholecystectomy and inguinal hernia repair.

BACKGROUND: Emergency Department (ED) utilization following general surgery procedures is poorly understood and places immense strain on the healthcare system. Inefficient ED utilization is responsible for up to $38 billion in wasteful spending annually. Nearly 56% of ED visits may be avoidable. The aim of our study was to quantify ED utilization following elective cholecystectomy (CCY) and inguinal hernia repair (IHR), to characterize the impact and identify causes. MATERIALS AND METHODS: This retrospective study included patients across eight hospitals in a single health system undergoing elective CCY and IHR between January 2018 to June 2019. Patients who returned to the ED within 30 and 90 days were analyzed for hospital readmission, preventability (based on the Goldfield criteria), relation to index surgery and clinician communication within 48 h of presentation. RESULTS: In total, 3678 patients had elective surgery in this timeframe. Of these, 476 patients (13.1%) visited the ED at least once within 90 days from their surgical admission discharge date and 114 were readmitted to the hospital (23.9%). Average length from discharge to ED presentation was 27.1 days. The mean cost associated with these ED visits was $974 per visit. 31.9% communicated with their clinician within 48 h of ED presentation. 73.9% of ED visits occurred between Monday - Friday and 51.5% took place between the hours of 8 am-5 pm. 46.6% of ED visits were related to the index operation and 40.7% of ED visits were deemed preventable. CONCLUSIONS: While hospital readmissions have been scrutinized in the literature, relatively little is known about postoperative ED utilization. Our study is one of the first to document postoperative ED utilization up to 90 days after surgery. For just two common elective general surgery procedures, we found these visits were financially burdensome and led to ED discharge in > 75% of patients. Numerous opportunities to improve care were identified. Most ED visits occurred on weekdays and during daylight hours, suggesting an opportunity to utilize outpatient clinics in lieu of the ED. Nearly 50% were related to the operation and nearly 40% were preventable. Revamping the discharge instructions and post-discharge communication-including novel strategies leveraging telemedicine-by providers has the potential to dramatically decrease postoperative ED utilization.

Application Factors May Not Be Predictors of Success Among General Surgery Residents as Measured by ACGME Milestones.

BACKGROUND: Can factors within the Electronic Residency Application Service application be used to predict the success of general surgery residents as measured by the Accreditation Council for Graduate Medical Education (ACGME) general surgery milestones? METHODS: This is a retrospective study of 21 residents who completed training at a single general surgery residency program. Electronic Residency Application Service applications were reviewed for objective data, such as age, US Medical Licensing Examination scores, and authorship of academic publications as well as for letters of recommendation, which were scored using a standardized grading system. These factors were correlated to resident success as measured by ACGME general surgery milestone outcomes using univariate and multivariate analyses. This study was conducted at a single academic tertiary care and level 1 trauma facility. Residents who completed general surgery residency training from the years of 2012-2018 were included in the study. RESULTS: There were few correlations between application factors and resident success determined by the ACGME milestones. CONCLUSIONS: Application factors alone do not account for ongoing growth and development throughout residency. Unlike the results presented in the literature for other surgical subspecialties, predicting general surgery resident success based on application factors is not straightforward.

External Validation of a Survival Nomogram for Non-Small Cell Lung Cancer Using the National Cancer Database.

PURPOSE: Survival nomograms offer individualized predictions using a more diverse set of factors than traditional staging measures, including the American Joint Committee on Cancer Tumor Node Metastasis (AJCC TNM) Staging System. A nomogram predicting overall survival (OS) for resected, non-metastatic non-small cell lung cancer (NSCLC) has been previously derived from Asian patients. The present study aims to determine the nomogram's predictive capability in the US using the National Cancer Database (NCDB). METHODS: This was a retrospective review of adults with resected, non-metastatic NSCLC entered into the NCDB between 2004 and 2012. Concordance indices and calibration plots analyzed discrimination and calibration, respectively. Multivariate analysis was also used. RESULTS: A total of 57,313 patients were included in this study. The predominant histologies were adenocarcinoma (48.2%) and squamous cell carcinoma (31.3%), and patients were diagnosed with stage I-A (38.3%), stage I-B (22.7%), stage II-A (14.2%), stage II-B (11.5%), and stage III-A (13.3%). Median OS was 74 months. 1-, 3- and 5-year OS rates were 89.8% [95% confidence interval (CI) 89.5-90.0%], 71.1% (95% CI 70.7-71.6%), and 55.7% (95% CI 54.7-56.6%), respectively. The nomogram's concordance index (C-index) was 0.804 (95% CI 0.792-0.817). AJCC TNM staging demonstrated higher discrimination (C-index 0.833, 95% CI 0.821-0.840). CONCLUSIONS: The nomogram's individualized estimates accurately predicted survival in this patient collective, demonstrating higher discrimination in this population than in the developer's cohorts. However, the generalized survival estimates provided by traditional staging demonstrated superior predictive capability; therefore, AJCC TNM staging should remain the gold standard for the prognostication of resected NSCLC in the US.

Patency and limb salvage after femoral endarterectomy and iliac stenting are not affected by severity of iliac disease.

OBJECTIVE: The hybrid procedure of femoral endarterectomy and iliac artery stenting (FEIS) has been used as an alternative to traditional open surgical repair of iliofemoral arterial occlusive disease, but whether the severity of the iliac disease component affects long-term results is not well understood. METHODS: This was a retrospective cohort study of patients undergoing FEIS at Geisinger Health System from January 1, 2004, through December 31, 2013, for the treatment of symptomatic iliofemoral atherosclerotic occlusive disease. The cohort was stratified according to the severity of the iliac occlusive disease component into patients with mild iliac disease (group 1) and patients with severe iliac disease (group 2). RESULTS: Between January 1, 2004, and December 31, 2013, 99 patients underwent 111 total FEIS procedures. The mean age of the cohort was 67.4 years. Men composed 61% of patients. Indications for surgery were claudication (41%), ischemic rest pain (36%), and tissue loss (23%). At 5 years of follow-up, there was no difference in primary patency (73% in group 1 vs 68% in group 2 [P = .67]) and limb salvage (90% in group 1 vs 92% in group 2 [P = .51]). There was a trend toward higher overall mortality in group 2 patients vs group 1 patients (53% vs 81%; P = .08), but this did not reach statistical significance. Univariate analysis did not identify any device-related or anatomic factors predictive of patency. CONCLUSIONS: When combined iliofemoral arterial occlusive disease is treated with FEIS, the severity of the iliac disease component does not affect long-term patency or limb salvage.

Analgesic Choice in Management of Rib Fractures: Paravertebral Block or Epidural Analgesia?

BACKGROUND: Rib fractures are commonly encountered in the setting of trauma. The aim of this study was to assess the association between the clinical outcome of rib fracture and epidural analgesia (EA) versus paravertebral block (PVB) using the National Trauma Data Bank (NTDB). METHODS: Using the 2011 and 2012 versions of the NTDB, we retrieved completed records for all patients above 18 years of age who were admitted with rib fractures. Primary outcome was in-hospital mortality. Secondary outcomes were length of stay (LOS), intensive care unit (ICU) admission, ICU LOS, mechanical ventilation, duration of mechanical ventilation, development of pneumonia, and development of any other complication. Clinical outcomes were first compared between propensity score-matched EA and PVB patients. Then, EA and PVB patients were combined into the procedure group and the outcomes were compared with propensity score-matched patients that received neither intervention (no-procedure group). RESULTS: A total of 194,766 patients were included in the study with 1073 patients having EA, 1110 patients having PVB, and 192,583 patients having neither procedure. After propensity score matching, comparison of primary and secondary outcomes between EA and PVB patients showed no difference. Comparison of propensity score-matched procedure and no-procedure patients showed prolonged LOS and more frequent ICU admissions in patients receiving a procedure (both P < .0001), yet having no procedure was associated with a significantly increased odds of mortality (odds ratio: 2.25; 95% confidence interval, 1.14-3.84; P = .002). CONCLUSIONS: Using the NTDB, EA and PVB were not found to be significantly different in management of rib fractures. There was an association between use of a block and improved outcome, but this could be explained by selection of healthier patients to receive a block. Prospective study of this association is recommended.

Value of delayed duplex ultrasound assessment after endothermal ablation of the great saphenous vein.

OBJECTIVE: Endothermal ablation (ETA) of the great saphenous vein (GSV) is associated with a small but definite risk of endothermal heat-induced thrombosis (EHIT) extending into the common femoral vein. Follow-up duplex ultrasound imaging to detect EHIT after ETA is considered standard of care, although the exact timing of duplex ultrasound imaging to detect EHIT after ETA remains unclear. We hypothesized that an additional duplex ultrasound assessment 1 week after ETA would not identify a significant number of patients with EHIT and would significantly increase health care costs. METHODS: This was a retrospective review of consecutive ETA GSV procedures from 2007 to 2014. All patients were evaluated with duplex ultrasound imaging on postprocedure day 1, and 79% of patients underwent a second ultrasound assessment 1 week postprocedure. EHIT was considered present when proximal GSV closure progressed to level ≥4, based on a six-tier classification system. RESULTS: From January 1, 2007, until December 31, 2014, 842 patients underwent GSV ETA. Patients with EHIT were more likely to have had a prior deep venous thrombosis (DVT; P = .002) and a larger GSV (P = .006). Forty-three procedures (5.1%) were classified as having EHIT requiring anticoagulation, based on a level ≥4 proximal closure level. Of the 43 patients with EHIT, 20 (47%) were found on the initial ultrasound assessment performed 24 hours postprocedure, but 19 patients (44%) with EHIT would not have been identified with a single postoperative ultrasound scan performed 24 hours after intervention. These 19 patients had a level ≤3 closure level at the duplex ultrasound scan performed 24 hours postprocedure and progressed to EHIT on the delayed duplex ultrasound scan. Lastly, thrombotic complications in four patients (9%), representing three late DVT and one DVT/pulmonary embolism presenting to another hospital, would not have been identified regardless of the postoperative surveillance strategy. Maximum GSV diameter was the only significant predictor of progression to EHIT on multivariate analysis (P = .007). Based on 2014 United States dollars, the two-ultrasound surveillance paradigm is associated with health care charges of $31,109 per identified delayed venous thromboembolism event. CONCLUSIONS: Delayed duplex ultrasound assessment after ETA of the GSV comes with associated health care costs but does yield a significant number of patients with progression to EHIT. Better understanding of the timing, risk factors, and significance of EHIT is needed to cost-effectively care for patients after ETA for varicose veins.

Utility of Prophylactic Antibiotics in Nonoperative Facial Fractures.

Facial fractures are commonly managed nonoperatively. Patients with facial fractures involving sinus cavities commonly receive 7 to 10 days of prophylactic antibiotics, yet no literature exists to support or refute this practice. The aim of this study was to compare the administration and duration of antibiotic prophylaxis on the incidence of soft tissue infection in nonoperative facial fractures. A total number of 289 patients who were admitted to our level I trauma center with nonoperative facial fractures from the beginning of 2012 to the end of 2014 were studied. Patients were categorized into 3 groups: no antibiotic prophylaxis, short-term antibiotic prophylaxis (1-5 days), and long-term antibiotic prophylaxis (>5 days). The primary outcome was the incidence of facial soft tissue infection and Clostridium difficile colitis. Fifty patients received no antibiotic prophylaxis. Sixty-three patients completed a short course of antibiotic prophylaxis and 176 patients received long-term antibiotics. Ampicillin/sulbactam, amoxicillin/clavulanic acid, or a combination of both were used in 216 patients. Twenty-three patients received clindamycin due to penicillin allergy. Short and long courses of antibiotic prophylaxis were administered more commonly in patients with concomitant maxillary and orbital fractures (P <0.0001). No mortality was found in any group. Soft tissue infection was not identified in any patient. C. difficile colitis was identified in 1 patient who had received a long course of antibiotic prophylaxis (P = 0.7246). There was no difference in the outcome of patients receiving short-term, long-term, and no antibiotic prophylaxis. Prospective randomized studies are needed to provide further clinical recommendations.

The Correlation of Thyroid Hormone Levels and Anti-Thyroidal Drugs on Thyroid Size, Weight, and Ease of Surgical Dissection for Thyroidectomy for Graves' Disease.

BACKGROUND: Patients with Graves' Disease often have a larger thyroid size than patients without thyroid disease. These patients also have elevated T3 and T4 with decreased TSH. PURPOSE: We evaluate whether these thyroid labs, the use of antithyroid agents, or the size of a thyroid on ultrasound, correlate with the pathological size of a thyroid in patients who undergo total thyroidectomy for Graves' Disease. We further determine whether these parameters affect perioperative complications. RESEARCH DESIGN: A retrospective review of patients undergoing total thyroidectomy for Graves' Disease was performed from January 2004 to December 2016 in a single institution. STUDY SAMPLE: 392 patients were included in the study. DATA COLLECTION AND/OR ANALYSIS: Univariate analyses were performed to compare thyroid size on US and pathology as well as weight to preoperative thyroid hormone values and medical comorbidities. Spearman rank correlation and ANOVA were used to identify factors associated with thyroid weight, total pathology size, and differences in size. Multivariate analysis was also performed to evaluate for correlation between thyroid function and perioperative complications. RESULTS: We found that elevated pre-operative T3 levels were associated with larger pathologic size (P = .027) and a greater difference in pathology vs. US thyroid volumes (P = .005), but not increased thyroid weight (P = .286). No significant differences were found for thyroid weight, pathology size, or difference in size for TSH, T4, or any specific preoperative ATD given. Only postoperative calcium levels were found to be statistically significant for TSH < 0.27 (P = .024) for peri-operative complications. CONCLUSIONS: These findings may allow for more accurate preoperative planning and intraoperative expectations in patients with Graves' Disease.

Arm Health in Elite Collegiate Summer League Baseball Players Assessed by the Kerlan-Jobe Orthopaedic Clinic Score.

CONTEXT: Collegiate baseball players with professional aspirations often participate in summer leagues; foremost among them is the Cape Cod Baseball League (CCBL). Injuries acquired during the collegiate baseball season can be carried into the CCBL season and vice versa. OBJECTIVE: To assess the history of throwing arm injury and current functionality in midseason CCBL players. DESIGN: Cross-sectional study. SETTING: Online questionnaire. PATIENTS OR OTHER PARTICIPANTS: A total of 123 CCBL players participated. Qualifying athletes were ≥18 years old and were rostered CCBL players with remaining collegiate eligibility. MAIN OUTCOME MEASURE(S): After collecting background information, we used the Kerlan-Jobe Orthopaedic Clinic (KJOC) Shoulder and Elbow questionnaire to assess the history of throwing arm injury and current functionality. The maximum KJOC score is 100.0; higher scores correspond with greater functionality. RESULTS: The mean KJOC score was 86.6 ± 14.5 (n = 92); 24.5% (23/94) of players reported a prior diagnosis of throwing arm injury other than a strain or sprain. A total of 49 (49/96, 51.0%) players had undergone rehabilitation for a throwing arm injury, and 7 (7/96, 7.3%) had experienced a medical procedure. Players with no previous treatment (n = 41, mean KJOC score = 88.9 ± 19.0) more frequently demonstrated KJOC scores of ≥90 than players with such treatment (n = 55, 80.9 ± 17.1; P < .001). The 18 players with time-loss arm injury in the last year had lower mean KJOC scores (71.3 ± 20.0) than players with no injury or time loss (90.3 ± 9.8; P < .001). Similarly, players who reported current arm trouble (n = 15) had lower KJOC scores (71.6 ± 17.5) than players with healthy arms (89.5 ± 11.9; P < .001). CONCLUSIONS: The average KJOC score of the CCBL players was <90, with particularly low scores in athletes with prior arm injury and treatment.

Genome-first approach of the prevalence and cancer phenotypes of pathogenic or likely pathogenic germline TP53 variants.

Pathogenic or likely pathogenic (P/LP) germline TP53 variants are the primary cause of Li-Fraumeni syndrome (LFS), a hereditary cancer predisposition disorder characterized by early-onset cancers. The population prevalence of P/LP germline TP53 variants is estimated to be approximately one in every 3,500 to 20,000 individuals. However, these estimates are likely impacted by ascertainment biases and lack of clinical and genetic data to account for potential confounding factors, such as clonal hematopoiesis. Genome-first approaches of cohorts linked to phenotype data can further refine these estimates by identifying individuals with variants of interest and then assessing their phenotypes. This study evaluated P/LP germline (variant allele fraction ≥30%) TP53 variants in three cohorts: UK Biobank (UKB, n = 200,590), Geisinger (n = 170,503), and Penn Medicine Biobank (PMBB, n = 43,731). A total of 109 individuals were identified with P/LP germline TP53 variants across the three databases. The TP53 p.R181H variant was the most frequently identified (9 of 109 individuals, 8%). A total of 110 cancers, including 47 hematologic cancers (47 of 110, 43%), were reported in 71 individuals. The prevalence of P/LP germline TP53 variants was conservatively estimated as 1:10,439 in UKB, 1:3,790 in Geisinger, and 1:2,983 in PMBB. These estimates were calculated after excluding related individuals and accounting for the potential impact of clonal hematopoiesis by excluding heterozygotes who ever developed a hematologic cancer. These varying estimates likely reflect intrinsic selection biases of each database, such as healthcare or population-based contexts. Prospective studies of diverse, young cohorts are required to better understand the population prevalence of germline TP53 variants and their associated cancer penetrance.

Post-Discharge Outcomes After Pancreatic Necrosectomy: A Single Institution Experience Following Endoscopic vs Open Debridement.

BACKGROUND: Pancreatic necrosectomy outcomes have been studied extensively; however, long-term results of these procedures have not been well characterized. Our study aimed to assess the outcomes at and after discharge for patients following necrosectomy. METHODS: Data from patients undergoing pancreatic necrosectomy at a single tertiary referral hospital from January 1, 2007, to June 1, 2019 were retrospectively analyzed. Patients were stratified into an open pancreatic necrosectomy (OPN) and an endoscopic pancreatic necrosectomy (EPN) group. RESULTS: Cohorts were composed of an OPN (n = 30) and EPN (n = 31) groups with a mean follow-up of 22 and 13.5 months, respectively. There was no statistically significant difference in the demographics or etiology of disease; however, the presence of severe sepsis and elevated BISAP scores was significantly higher in the OPN group (40% vs 13% p = .016, 37% vs 10% p = .012, respectively). There was no significant difference in discharge parameters or disposition other than a higher need for wound care in the OPN group (14% vs 0% p =< .0001). No significant difference in the number of patients who returned to baseline, 12-month ED visits, 12-month readmissions, medical comorbidities, or long-term survival was noted. CONCLUSIONS: Previous studies have demonstrated that OPN patients have a higher severity of disease and higher inpatient mortality; however, this does not hold true once the acute phase of the illness has passed. Long-term medical comorbidities and survival of patients with necrotizing pancreatitis who endure the primary insult do not differ in long term, regardless of the debridement modality performed for source control.

Resilience in Residency and Beyond.

¼ Distinct from the burnout and wellness continuum, resilience is a developed and refined characteristic that propels an individual toward personal and professional success.¼ We propose a clinical resilience triangle consisting of 3 components that define resilience: grit, competence, and hope.¼ Resilience is a dynamic trait that should be built during residency and constantly fortified in independent practice so that orthopaedic surgeons may acquire and hone the skills and mental fortitude required to take on the overwhelming challenges that we all inevitably face.

Older age and smaller joint space width are associated with conversion to total hip arthroplasty following hip arthroscopy.

Purpose: The goal of this study was to define the outcomes of patients following hip arthroscopy and to identify potential factors, found during hip arthroscopy, that were associated with patients' eventual conversion to total hip arthroplasty (THA). Methods: Patients who had undergone hip arthroscopy from January 2010 to January 2015 were retrospectively reviewed and patients were reported if they had a THA in the same hip. Patients were followed up to December 2022 resulting in between 7 and 12 years of follow-up. Measures from the hip scope including joint space width and cartilage grades were reported. Differences in these measures and demographics were compared between patients who had THA after hip arthroscopy and those who did not with T-tests. Results: Patients who had hip arthroscopy and were then converted to THA were significantly older than those patients who did not have THA (50.3 vs 42.0 years) (p = 0.039). The average time of conversion to THA from index hip arthroscopy was 3.59 years with a range of 0.48-8.91 years. Joint space width in patients converted to THA was significantly less, 3.08 mm ± 1.93 mm, compared to non-THA converted patients, 3.62 mm ± 0.88 mm (p < 0.001). Conclusions: Older age and smaller joint space width of the hip was associated with patients who were converted to THA following hip arthroscopy. Level of evidence: Level III.

Bilateral Tibial Tubercle Avulsion Fractures With an Associated Patellar Tendon Avulsion in an Adolescent Patient.

Tibial tubercle fractures in pediatric patients are increasing in frequency as more children participate in sports. These injuries are often seen in boys engaging in jumping activities before closure of their proximal tibial physis. Bilateral tibial tubercle fractures have been reported in the literature, but less frequent are associated patellar tendon ruptures with fracture of the tubercle. In this case report, we present an 11-year-old girl who sustained bilateral tibial tubercle fractures, including an associated patellar tendon rupture from the tubercle on the right lower extremity. We describe our technique for the management of both injuries, which included a primary patellar tendon repair for the right leg and Kirschner wire fixation of the displaced tubercle for the left leg. The patient ultimately had a successful outcome at the final follow-up with healed fractures and full range of motion of both knees. In this case report, we also present similar cases from the literature and the differing treatment strategies.

Lack of Consensus in Rehabilitation Protocols After Posterior Shoulder Stabilization.

Background: Posterior shoulder instability is being identified and treated more frequently by orthopaedic providers. After posterior shoulder stabilization, long-term outcomes in function and mobility are largely dependent on the postoperative rehabilitation period. Thus, it is important to assess the consistency between protocols at different institutions. Purpose/Hypothesis: The purpose of this study was to investigate the variability among rehabilitation protocols published by academic orthopaedic programs and their affiliates. It was hypothesized that there would be little consistency in the duration of immobilization, timing of functional milestones, and start dates of various exercises. Study Design: Cross-sectional study. Methods: Rehabilitation protocols after posterior shoulder stabilization that were published online from Accreditation Council for Graduate Medical Education (ACGME)-accredited orthopaedic surgery programs and their affiliates were evaluated for recommendations on immobilization, exercises, activities, range of motion (ROM), and return-to-sport goals. Results: Of the 204 ACGME-accredited orthopaedic surgery programs, 22 programs and 17 program affiliates had publicly available rehabilitation protocols that were included for review. There were 37 programs (94.9%) that recommended the use of sling immobilization for a mean of 4.7 ± 1.8 weeks postoperatively. Active ROM of the elbow, wrist, and hand was the most common early ROM exercise to be recommended (36 programs; 92.3%). The goal of 90° passive external rotation demonstrated the widest range of recommended start dates (0-12 weeks postoperatively). Late ROM exercises and start dates varied between protocols, with the largest standard deviation found in achieving full active ROM (13.5 ± 3.6 weeks). Resistance exercises showed a wide range of recommended start dates. Bench presses and push-ups began, on average, at 13.1 ± 3.4 and 15.3 ± 3.2 weeks, respectively. Return to sport was recommended at 21.7 ± 3.6 weeks. Conclusion: There was a high level of variability in postoperative rehabilitation protocols after posterior shoulder stabilization among orthopaedic programs and their affiliates, suggesting that a standard protocol for rehabilitation has yet to be established.
