Objective: This study aimed to identify risk criteria available before the point of treatment initiation that can be used to stratify the risk of obstruction in patients undergoing neoadjuvant chemotherapy (NAC) for high-risk colon cancer.
Background: Global implementation of NAC for colon cancer, informed by the FOxTROT trial, may increase the risk of bowel obstruction.
Methods: A case-control study, nested within an international randomized controlled trial (FOxTROT; ClinicalTrials.gov: NCT00647530). Patients with high-risk operable colon cancer (radiologically staged T3-4 N0-2 M0) that were randomized to NAC and developed large bowel obstruction were identified. First, clinical outcomes were compared between patients receiving NAC in FOxTROT who did and did not develop obstruction. Second, obstructed patients (cases) were age-matched and sex-matched with patients who did not develop obstruction (controls) in a 1:3 ratio using random sampling. Bayesian conditional mixed-effects logistic regression modeling was used to explore clinical, radiologic, and pathologic features associated with obstruction. The absolute risk of obstruction based on the presence or absence of risk criteria was estimated for all patients receiving NAC.
Results: Of 1053 patients randomized in FOxTROT, 699 received NAC, of whom 30 (4.3%) developed obstruction. Patients underwent care in European hospitals including 88 UK, 7 Danish, and 3 Swedish centers. There was more open surgery (65.4% vs 38.0%, P =0.01) and a higher pR1 rate in obstructed patients (12.0% vs 3.8%, P =0.004), but otherwise comparable postoperative outcomes. In the case-control-matched Bayesian model, 2 independent risk criteria were identified: (1) obstructing disease on endoscopy and/or being unable to pass through the tumor [adjusted odds ratio: 9.09, 95% credible interval: 2.34-39.66] and stricturing disease on radiology or endoscopy (odds ratio: 7.18, 95% CI: 1.84-32.34). Three risk groups were defined according to the presence or absence of these criteria: 63.4% (443/698) of patients were at very low risk (<1%), 30.7% (214/698) at low risk (<10%), and 5.9% (41/698) at high risk (>10%).
Conclusions: Safe selection for NAC for colon cancer can be informed by using 2 features that are available before treatment initiation and identifying a small number of patients with a high risk of preoperative obstruction.

Objective: The aim of this study was to assess indications for and report outcomes of pancreatic surgery in pediatric patients.
Background: Indications for pancreatic surgery in children are rare and data on surgical outcomes after pediatric pancreatic surgery are scarce.
Methods: All children who underwent pancreatic surgery at a tertiary hospital specializing in pancreatic surgery between 2003 and 2022 were identified from a prospectively maintained database. Indications, surgical procedures, and perioperative as well as long-term outcomes were analyzed.
Results: In total, 73 children with a mean age of 12.8 years (range: 4 mo to 18 y) underwent pancreatic surgery during the observation period. Indications included chronic pancreatitis (n=35), pancreatic tumors (n=27), and pancreatic trauma (n=11). Distal pancreatectomy was the most frequently performed procedure (n=23), followed by pancreatoduodenectomy (n=19), duodenum-preserving pancreatic head resection (n=10), segmental pancreatic resection (n=7), total pancreatectomy (n=3), and others (n=11). Postoperative morbidity occurred in 25 patients (34.2%), including 7 cases (9.6%) with major complications (Clavien-Dindo≥III). There was no postoperative (90-d) mortality. The 5-year overall survival was 90.5%. The 5-year event-free survival of patients with chronic pancreatitis was 85.7%, and 69.0% for patients with pancreatic tumors.
Conclusion: This is the largest single-center study on pediatric pancreatic surgery in a Western population. Pediatric pancreatic surgery can be performed safely. Centralization in pancreatic centers with high expertise in surgery of adult and pediatric patients is important as it both affords the benefits of pancreatic surgery experience and ensures that surgical management is adapted to the specific needs of children.

Objective: To critically examine the evidence-base for survival benefit of pulmonary metastasectomy (PM) for osteosarcoma (OS) in the pediatric population.
Background: PM for OS is recommended as the standard of care in both pediatric and adult treatment protocols. Recent results from the "Pulmonary Metastasectomy in Colorectal Cancer" trial demonstrate no survival benefit from PM in colorectal cancer in adults.
Methods: A systematic review was undertaken according to "Preferred Reporting Items for Systematic Reviews and Meta-Analysis" guidelines. Medline, Embase, and 2 clinical trial registers were searched for all studies detailing pediatric patients with OS (<18 years) undergoing PM with a comparison cohort group that did not receive PM.
Results: Eleven studies met inclusion criteria dating from 1984 to 2017. All studies were retrospective and none directly compared PM versus no PM in pediatric patients as its main objective(s). Three-year survival rates ranged from 0% to 54% for PM and 0% to 16% for no PM. No patients receiving PM were usually those with unresectable disease and/or considered to have a poor prognosis. All studies were at high risk of bias and there was marked heterogeneity in the patient selection.
Conclusions: There is a weak evidence base (level IV) for a survival benefit of PM for OS in pediatric patients likely due to selection bias of "favorable cases." The included studies many of which detailed outdated treatment protocols were not designed in their reporting to specifically address the questions directly. A randomized controlled trial-while ethically challenging in a pediatric population-incorporating modern OS chemotherapy protocols is needed to crucially address any "survival benefit."

Objective: The aim of this study was to develop a novel machine learning model to predict clinically relevant postoperative pancreatic fistula (CR-POPF) following pancreaticoduodenectomy (PD).
Background: Accurate prognostication of CR-POPF may allow for risk stratification and adaptive treatment strategies for potential PD candidates. However, antecedent models, such as the modified Fistula Risk Score (mFRS), are limited by poor discrimination and calibration.
Methods: All records entailing PD within the 2014 to 2018 American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) were identified. In addition, patients undergoing PD at our institution between 2013 and 2021 were queried from our local data repository. An eXtreme Gradient Boosting (XGBoost) model was developed to estimate the risk of CR-POPF using data from the ACS NSQIP and evaluated using institutional data. Model discrimination was estimated using the area under the receiver operating characteristic (AUROC) and area under the precision recall curve (AUPRC).
Results: Overall, 12,281 and 445 patients undergoing PD were identified within the 2014 to 2018 ACS NSQIP and our institutional registry, respectively. Application of the XGBoost and mFRS scores to the internal validation dataset revealed that the former model had significantly greater AUROC (0.72 vs 0.68, P <0.001) and AUPRC (0.22 vs 0.18, P <0.001). Within the external validation dataset, the XGBoost model remained superior to the mFRS with an AUROC of 0.79 (95% CI: 0.74-0.84) versus 0.75 (95% CI: 0.70-0.80, P <0.001). In addition, AUPRC was higher for the XGBoost model, compared with the mFRS.
Conclusion: Our novel machine learning model consistently outperformed the previously validated mFRS within internal and external validation cohorts, thereby demonstrating its generalizability and utility for enhancing prediction of CR-POPF.

Objective: To demonstrate that the creation of a Center for Trauma Survivorship (CTS) is not cost-prohibitive but is a revenue generator for the institution.
Background: A dedicated CTS has been demonstrated to increase adherence with follow-up visits and improve overall aftercare in severely injured patients discharged from the trauma center. A potential impediment to the creation of similar centers is its assumed prohibitive cost.
Methods: This pre and post-cohort study examines the financial impact of patients treated by the CTS. Patients in the PRE cohort were those treated in the year before CTS inception. Eligibility criteria are trauma patients admitted who are ≥18 years of age and have a New Injury Severity Score ≥16 or intensive care unit stay ≥2 days. Financial data were obtained from the hospital's billing and cost accounting systems for a 1-year time period after discharge.
Results: There were 176 patients in the PRE and 256 in the CTS cohort. The CTS cohort generated 1623 subsequent visits versus 748 in the PRE cohort. CTS patients underwent more follow-up surgery in their first year of recovery as compared with the PRE cohort (98 vs 26 procedures). Each CTS patient was responsible for a $7752 increase in net revenue with a positive contribution margin of $4558 compared with those in the PRE group.
Conclusions: A dedicated CTS increases subsequent visits and necessary procedures and is a positive revenue source for the trauma center. The presumptive financial burden of a CTS is incorrect and the creation of dedicated centers will improve patients' outcomes and the institution's bottom line.

Objective: To define recent trends in opioid prescribing after surgery and new persistent opioid use in the United States.
Summary background data: New persistent opioid use after surgery among opioid-naïve individuals has emerged as an important postoperative complication. In response, initiatives to promote more appropriate post-operative opioid prescribing have been adopted in recent years. However, current estimates of opioid prescribing and new persistent opioid use following surgery remain unknown.
Methods: A retrospective cohort study of opioid-naïve privately insured adult patients undergoing 17 common surgical procedures between 2013 and 2021 was conducted utilizing multi-payer claims data from the Health Care Cost Institute (HCCI). Initial opioid prescription size in oral morphine equivalents and new persistent opioid use were the outcomes of interest. Trends in opioid prescribing and rates of new persistent opioid use were evaluated across the study period. Mixed effects logistic regression was performed to evaluate independent predictors of new persistent opioid use while adjusting for patient-level factors and year.
Results: Among 989,354 opioid-naïve individuals, the adjusted initial opioid prescription size decreased from 282 mg OME to 164 mg OME, a reduction of 118 mg OME (95% CI: 116-120). The adjusted incidence of new persistent opioid use decreased from 2.7% in 2013 (95% CI: 2.6%-2.8%) to 1.1% in 2021 (95% CI: 1.0%-1.2%). For every 30 OME increase in initial opioid prescription size, new persistent opioid use increased by 3.1%. Other predictors of new persistent opioid use included preoperative non-opioid controlled substances fills (31-365 days: aOR=1.78, 95% CI: 1.70-1.86; 0-30 days: aOR=2.71, 95% CI: 2.59-2.84) and undergoing orthopedic procedures (total knee arthroplasty (aOR=3.43, 95% CI: 3.15-3.72); shoulder arthroscopy (aOR=2.39, 95% CI: 2.24-2.56)).
Conclusions: Both opioid prescription size after surgery and new persistent opioid use decreased over the last decade, suggesting that opioid stewardship practices had favorable effects on the risk of long-term opioid use.

Objective: To compare hospital surgical performance in older and younger patients.
Background: In-hospital mortality after surgical procedures varies widely among hospitals. Prior studies suggest that failure-to-rescue rates drive this variation for older adults, but the generalizability of these findings to younger patients remains unknown.
Methods: We performed a retrospective cohort study of patients ≥18 years undergoing one of 10 common and complex general surgery operations in 16 states using the Healthcare Cost and Utilization Projects State Inpatient Databases (2016-2018). Patients were split into 2 populations: patients with Medicare ≥65 (older adult) and non-Medicare <65 (younger adult). Hospitals were sorted into quintiles using risk-adjusted in-hospital mortality rates for each age population. Correlations between hospitals in each mortality quintile across age populations were calculated. Complication and failure-to-rescue rates were compared across the highest and lowest mortality quintiles in each age population.
Results: We identified 579,582 patients treated in 732 hospitals. The mortality rate was 3.6% among older adults and 0.7% among younger adults. Among older adults, high- relative to low-mortality hospitals had similar complication rates (32.0% vs 29.8%; P = 0.059) and significantly higher failure-to-rescue rates (16.0% vs 4.0%; P < 0.001). Among younger adults, high-relative to low-mortality hospitals had higher complications (15.4% vs 12.1%; P < 0.001) and failure-to-rescue rates (8.3% vs 0.7%; P < 0.001). The correlation between observed-to-expected mortality ratios in each age group was 0.385 ( P < 0.001).
Conclusions: High surgical mortality rates in younger patients may be driven by both complication and failure-to-rescue rates. There is little overlap between low-mortality hospitals in the older and younger adult populations. Future work must delve into the root causes of this age-based difference in hospital-level surgical outcomes.

Objective: The aim of this study was to compare rates and severity of recurrent acute diverticulitis in patients with and without solid organ transplant.
Background: Immunocompromised solid organ transplant recipients have been considered higher risk for both recurrence and severity of acute diverticulitis. Current guidelines recommend an individualized approach for colectomy in these patients, but these are based on single-center data.
Methods: We identified patients with acute diverticulitis using the Merative MarketScan commercial claims data from 2014 to 2020. Patients were classified by history of solid organ transplant. The primary outcome was recurrence of acute diverticulitis with an associated antibiotic prescription ≥60 days from the initial episode. Secondary outcomes included hospitalization, colectomy, and ostomy in patients with recurrence. Analyses used inverse probability weighting to adjust for imbalances in covariates.
Results: Of 170,697 patients with evidence of acute diverticulitis, 442 (0.2%) had a history of solid organ transplantation. In the weighted cohort, among people who had not been censored at 1 year (n=515), 112 (22%; 95% CI: 20%-25%) experienced a recurrence within the first year. Solid organ transplantation was not significantly associated with a risk of recurrence (hazard ratio=1.19; 95% CI: 0.94-1.50). There was also no statistically significant difference in the hospitalization rate for recurrent diverticulitis. Restricting the analysis to hospitalized recurrences, there was no statistically significant difference observed in either length of stay or discharge status.
Conclusions: In this national analysis of commercially insured patients with acute diverticulitis we found no statistically significant differences in recurrence between those with and without a history of solid organ transplant. We do not support an aggressive colectomy strategy based on concern for increased recurrence rate and severity in a solid organ transplant population.
目的:比较接受和未接受实体器官移植的急性憩室炎复发率和严重程度。摘要背景资料:免疫功能低下的实体器官移植受者被认为急性憩室炎复发和严重程度的风险更高。目前的指南建议对这些患者采用个体化的结肠切除术方法,但这些都是基于单中心数据。方法:我们使用2014-2020年的Merative MarketScan商业索赔数据识别急性憩室炎患者。患者按实体器官移植史进行分类。主要结局是急性憩室炎复发,且与初始发作相关的抗生素处方≥60天。次要结局包括复发患者住院、结肠切除术和造口术。分析使用逆概率加权来调整协变量的不平衡。结果:170,697例急性憩室炎患者中,442例(0.2%)有实体器官移植史。在加权队列中,在一年内未被审查的人中(n=515), 112人(22%;95% CI(20%-25%)在一年内复发。实体器官移植与复发风险无显著相关性(HR 1.19;95% ci 0.94-1.50)。复发性憩室炎的住院率也无统计学差异。限制对住院复发的分析,在住院时间和出院状态方面没有观察到统计学上的显著差异。结论:在这项对商业保险急性憩室炎患者的全国分析中,我们发现有和没有实体器官移植史的患者在复发方面没有统计学上的显著差异。基于对实体器官移植人群复发率和严重程度增加的担忧,我们不支持积极的结肠切除术策略。
