Background

Frailty has been recognized as an independent risk factor for adverse postoperative outcomes. Coding based frailty instruments such as the Modified Frailty Index (mFI-5) are increasingly incorporated into risk models to provide better prediction of mortality, and complications. However, few have examined the large-scale utility of mFI-5 in the context of mastectomy and breast reconstruction.

Methods

All elective adult (≥ 18 years) hospitalizations in women for mastectomy, with and without immediate breast reconstruction (IBR) were identified in the 2016–2022 National Inpatient Sample. Patients with an mFI-5 score ≥ 2 were considered Frail. Multivariable regression models were constructed to evaluate the association of frailty with major complications, length of stay (LOS) and inpatient costs.

Results

Of an estimated 150,215 patients, 14 % were considered Frail. The proportion of frail patients was increased from 13 % to 16 % during the study period. Relative to others, Frail had a greater mean Elixhauser Index (4.49 ± 1.51 vs 1.89 ± 1.29, P < 0.001), was more commonly of Black race (23.7 vs 11.8 %, P < 0.001) and of the lowest income quartile (29.8 vs 17.1 %, P < 0.001).
Following comprehensive risk adjustment, frailty was associated with increased odds of infectious (AOR 2.36, CI 1.35–4.13), respiratory (AOR 2.05, CI 1.44–2.92), and renal (AOR 5.62, CI 4.16–7.60) complications. Moreover, frailty was associated with greater length of stay, but no difference in hospitalization costs.

Conclusions

Frailty remains associated with greater postoperative complications and length of stay. Status of frailty as ascertained by the mFI-5 may be useful in stratifying patient risk among those receiving mastectomy.
背景:虚弱已被认为是术后不良结果的独立危险因素。基于编码的脆弱性工具,如修正脆弱性指数(mFI-5)越来越多地被纳入风险模型,以更好地预测死亡率和并发症。然而,很少有人研究mFI-5在乳房切除术和乳房重建中的大规模应用。方法在2016-2022年全国住院患者样本中确定所有选择性成年(≥18岁)住院的女性乳房切除术,伴或不伴立即乳房重建(IBR)。mFI-5评分≥2的患者被认为虚弱。我们构建了多变量回归模型来评估虚弱与主要并发症、住院时间(LOS)和住院费用的关系。结果在150,215名患者中,14%被认为虚弱。在研究期间,体弱患者的比例从13%增加到16%。相对于其他人,体弱者的平均Elixhauser指数更高(4.49±1.51 vs 1.89±1.29,P < 0.001),更常见于黑人(23.7 vs 11.8%, P < 0.001)和最低收入四分位数(29.8 vs 17.1%, P < 0.001)。综合风险调整后,虚弱与感染(AOR 2.36, CI 1.35-4.13)、呼吸(AOR 2.05, CI 1.44-2.92)和肾脏(AOR 5.62, CI 4.16-7.60)并发症的发生率增加相关。此外,虚弱与更长的住院时间有关,但住院费用没有差异。结论虚弱仍与术后并发症和住院时间有关。由mFI-5确定的虚弱状态可能有助于对接受乳房切除术的患者进行风险分层。

Objective

To evaluate the efficacy and safety of timely staged hepatectomy (SH) following transarterial embolization (TAE) versus emergency hepatectomy (EH) for spontaneous rupture of hepatocellular carcinoma (SR-HCC).

Methods

Between January 2018 and December 2023, 109 patients with SR-HCC were admitted to our center receive SH (34 cases) or EH (75 cases). Performing 1:1 optimal matching propensity score matching (PSM) analysis, resulting in 34 patients in SH group and 34 patients in EH group. We compared perioperative data, peritoneal metastasis rates, recurrence rates, complication rates, and long-term survival outcome between the two matched groups.

Results

After PSM, baseline characteristics were well balanced between the SH and EH groups (standardized mean difference [SMD] < 0.1). Compared with the matched EH group, the SH group had a shorter intraoperative hepatic vascular clamping time, significantly less perioperative blood loss and transfusion volume, and a lower in-hospital mortality rate (P < 0.05). No significant differences were observed between the two groups in postoperative complication rates and peritoneal metastasis rates (P > 0.05). The SH group exhibited a trend toward improved recurrence-free survival (RFS) (Log-rank χ2 = 3.2, P = 0.074), although this did not reach statistical significance. Similarly, overall survival (OS) was comparable between the groups (Log-rank χ2 = 1.78, P = 0.183).

Conclusion

Compared with EH, SH demonstrates superior perioperative safety, characterized by less surgical trauma and lower in-hospital mortality, without increasing postoperative complications and the risk of peritoneal metastasis. Therefore, SH may be considered the preferred treatment for SR-HCC, especially in cases of hemodynamic instability or impaired hepatic functional reserve.
目的评价经动脉栓塞(TAE)后及时分期肝切除术(SH)与急诊肝切除术(EH)治疗自发性肝癌(SR-HCC)的疗效和安全性。方法2018年1月至2023年12月,109例SR-HCC患者接受SH(34例)或EH(75例)治疗。进行1:1最优匹配倾向评分匹配(PSM)分析,SH组34例,EH组34例。我们比较了两组患者的围手术期数据、腹膜转移率、复发率、并发症发生率和长期生存结果。结果经PSM后,SH组和EH组的基线特征平衡良好(标准化平均差[SMD] <; 0.1)。与匹配的EH组相比,SH组术中肝血管夹持时间更短,围术期出血量和输血量明显减少,住院死亡率更低(P < 0.05)。两组术后并发症发生率及腹膜转移率比较差异无统计学意义(P > 0.05)。SH组无复发生存率(RFS)有改善趋势(Log-rank χ2 = 3.2, P = 0.074),但差异无统计学意义。同样,两组间总生存期(OS)具有可比性(Log-rank χ2 = 1.78, P = 0.183)。结论与EH相比,SH具有更强的围手术期安全性,手术创伤小,住院死亡率低,术后并发症和腹膜转移风险无增加。因此,SH可能被认为是SR-HCC的首选治疗方法,特别是在血流动力学不稳定或肝功能储备受损的情况下。

Background

Peptic ulcer disease continues to be a major health concern. Surgical intervention is usually reserved for complications, such as pyloric stenosis, leading to gastric outlet obstruction. We compared the outcomes of laparoscopic and open surgery.

Materials and methods

This is a retrospective study comparing Laparoscopic Truncal vagotomy and Gastrojejunostomy with open procedure. We examined the medical records of 151 patients treated for peptic pyloric stenosis at La Rabta Hospital in Tunis, Tunisia, from January 2000 to December 2018. The study focused on benign gastric outlet obstruction due to peptic ulcer disease, with patient progress monitored for over 24 months.

Results

A hundred and fifty-one patients treated for peptic ulcer stenosis by gastojejunostomy and truncal vagotomy were included in the study, featuring 52 cases of LTVGJ 99 cases ofOTVGJ. The male-to-female ratio was 5.2, with a mean age of 48 years for both groups. Perioperative outcomes revealed that OTVGJ had a shorter mean operative time (95 min) compared to LTVGJ (115 min), while the median hospital stay was longer for OTVGJ (7.9 days) versus LTVGJ (5.5 days). Both groups exhibited similar rates of delayed gastric emptying and postoperative gastrointestinal symptoms, with no cases of leakage or operative mortality. Diabetes was the only significant risk factor for delayed gastric emptying.

Conclusion

Laparoscopic truncal vagotomy and gastrojejunostomy for gastric outlet obstruction secondary to peptic ulcer disease is a safe and effective modality, offers low morbidity and satisfactory clinical status on long term follow up.
背景:消化性溃疡疾病一直是一个主要的健康问题。手术干预通常用于并发症,如幽门狭窄,导致胃出口梗阻。我们比较了腹腔镜和开放手术的结果。材料与方法回顾性比较腹腔镜下迷走神经截切和胃空肠吻合术与开放式手术的疗效。我们检查了2000年1月至2018年12月在突尼斯突尼斯La Rabta医院治疗的151例消化性幽门狭窄患者的医疗记录。该研究的重点是消化性溃疡引起的良性胃出口梗阻,对患者的进展进行了超过24个月的监测。结果纳入经胃空肠吻合术加迷走神经截尾术治疗消化性溃疡狭窄患者151例,其中LTVGJ 52例,otvgj 99例。男女比例为5.2,两组的平均年龄为48岁。围手术期结果显示,与LTVGJ(115分钟)相比,OTVGJ的平均手术时间(95分钟)较短,而OTVGJ的中位住院时间(7.9天)较LTVGJ(5.5天)更长。两组均表现出相似的胃排空延迟率和术后胃肠道症状,无漏或手术死亡病例。糖尿病是胃排空延迟的唯一显著危险因素。结论腹腔镜迷走神经截尾联合胃空肠吻合术治疗消化性溃疡继发性胃出口梗阻是一种安全有效的手术方式,发病率低,长期随访效果满意。

Diversity and inclusion are increasingly recognized as critical components of effective surgical practice and team dynamics. Despite growing awareness, structural barriers continue to limit the entry and advancement of individuals from underrepresented groups in surgery. At the annual meeting of the Dutch Surgical Society in 2025, a dedicated symposium on diversity and inclusion was organized to explore the relevance, urgency, and potential impact of these topics in surgery. Drawing from lived experience, research evidence, and a multidisciplinary panel discussion, this event underscored the necessity of shifting from performative diversity toward meaningful inclusion. Key insights from the symposium and actionable strategies to foster sustainable change within surgical education and practice are discussed in this paper. Future directions would include concrete policy development by the Dutch Surgical Society to achieve sustainable change, incorporating these topics in national education programs and development of structured mentorship networks and facilitating a continuous open dialogue.

Reconstruction of the digestive tract after extended left colectomy is a common challenge for colorectal surgeons. The main difficulty lies in lowering the colon into the pelvis to achieve a tension-free and well-vascularized anastomosis. We report our 10-year retrospective experience, in which a counterclockwise colonic transposition according to Lillehei and Wangensteen was performed in more than half of the cases. This technique differs from the more widely known Deloyers procedure solely by its axis of rotation. It offers the advantage of being more anatomical, easily reproducible, and functionally equivalent.
长时间左结肠切除术后消化道重建是结肠外科医生面临的一个共同挑战。主要的困难在于降低结肠进入骨盆,以实现无张力和血管通畅的吻合。我们报告了我们10年的回顾性经验,其中一半以上的病例根据Lillehei和Wangensteen进行了逆时针结肠转位。这种技术不同于更广为人知的Deloyers手术,唯一的区别是旋转轴。它具有解剖性更强、易于复制和功能等效的优点。

Background

Esophagectomy remains the cornerstone treatment for esophageal cancer but is associated with significant perioperative morbidity and mortality, even in specialized centers. Accurate preoperative risk assessment is crucial to improve patient outcomes, and various predictive models are available for risk stratification. This study aimed to validate and compare the performance of nine established predictive models in forecasting 30-day mortality following esophagectomy in a high-volume esophageal cancer center.

Methods

We retrospectively analyzed of 101 patients who underwent esophagectomy between January 2020 and December 2023 was performed. Clinicopathological characteristics and mortality data were obtained. The predictive accuracy of nine risk models, including the Esophageal-POSSUM (O-POSSUM), Charlson Comorbidity Index (Charlson), Postoperative Estimation of Risk (PER), and Fuchs scores, was assessed using logistic regression, Hosmer-Lemeshow tests for calibration, and the area under the receiver operating characteristic curve (AUC) for discrimination. Mann-Whitney U tests were used to evaluate significant differences between survivors and non-survivors.

Results

The 30-day mortality rate was 8.91 %. The O-POSSUM and Charlson scores demonstrated the highest predictive accuracy with AUCs of 0.832 and 0.806, respectively. The PER and Fuchs models also showed significant associations with mortality but with moderate predictive ability. Models such as the American Society of Anesthesiologists (ASA) and Philadelphia scores demonstrated limited predictive utility. Significant differences in predictive performance were noted across patient subgroups.

Conclusions

The O-POSSUM and Charlson scores were reliable tools for predicting 30-day mortality after esophagectomy. Other models require further validation and refinement. Tailoring risk assessment models in specific clinical settings may enhance their predictive accuracy and contribute to improved patient outcomes.
背景食管癌切除术仍是食管癌的基础治疗方法,但其围手术期发病率和死亡率较高,即使在专业中心也是如此。准确的术前风险评估对改善患者预后至关重要,各种预测模型可用于风险分层。本研究旨在验证和比较九种已建立的预测模型在预测食管癌大容量中心食管癌切除术后30天死亡率方面的表现。方法回顾性分析2020年1月至2023年12月行食管切除术的101例患者。获得临床病理特征和死亡率数据。9种风险模型,包括食道- possum (O-POSSUM)、Charlson共病指数(Charlson)、术后风险估计(PER)和Fuchs评分的预测准确性,采用logistic回归、Hosmer-Lemeshow检验进行校准,以及受试者工作特征曲线下面积(AUC)进行区分。使用Mann-Whitney U检验来评估幸存者和非幸存者之间的显著差异。结果30 d死亡率为8.91%。O-POSSUM和Charlson评分的预测准确率最高,auc分别为0.832和0.806。PER和Fuchs模型也显示出与死亡率的显著关联,但预测能力一般。美国麻醉师协会(ASA)和费城评分等模型显示出有限的预测效用。不同患者亚组在预测表现上存在显著差异。结论O-POSSUM和Charlson评分是预测食管切除术后30天死亡率的可靠工具。其他模型需要进一步验证和细化。在特定的临床环境中定制风险评估模型可以提高其预测的准确性,并有助于改善患者的预后。

Background

The impact of patient sex and race on clinical in-hospital outcomes and expenditures of falls in older adults remain underexplored. This study examines sex- and race-based disparities of fall-related hospitalizations.

Study design

All hospitalizations for adults (≥65 years) from falls were identified (National Inpatient Sample, 2017–2021). Patients were stratified into sex and racial groups (White and Non-White). Multivariable logistic (dichotomous variables) and linear (continuous variables) regression modeling compared clinical in-hospital outcomes, resource utilization, and hospital costs stratified by sex and race.

Results

An estimated 5,870,482 (survey-weighted) older adults experienced a fall-related hospital admission, with annual incidence rising from 1,108,024 to 1,210,547 (P < 0.001). Unadjusted in-hospital mortality was lower for females compared to males (2.5 vs 4.5 %, P < 0.001). Following risk-adjustment, females had lower odds of in-hospital mortality (AOR: 0.59, 95 %CI: 57–0.60, P < 0.001) and costs (β = −$1344, 95 %CI: −1321 to −1267, P < 0.001).
On crude analysis, in-hospital mortality was higher in Non-White patients (3.4 vs 3.2 %, P < 0.001). Mean LOS was longer for Non-White (6.31 ± 7.69 days) compared to White patients (5.65 ± 5.93 days, P < 0.001). Following risk-adjustment, Non-White patients had higher odds of in-hospital mortality compared to White patients (AOR: 1.16, 95 %CI: 1.08–1.24, P < 0.001) and higher median costs (β = $2304, 95 %CI: 1897.90-2710.16, P < 0.001).

Conclusion

Sex and race are associated with differences in clinical in-hospital outcomes and expenditures in older adult fall hospitalizations, suggesting potential variations in treatment, recovery, and access to care. Further research is needed to better understand these disparities and inform strategies for more equitable care.
患者性别和种族对老年人跌倒的临床住院结果和支出的影响仍未得到充分研究。本研究考察了因跌倒而住院的性别和种族差异。研究设计确定所有因跌倒住院的成人(≥65岁)(2017-2021年全国住院患者样本)。患者被分为性别和种族组(白人和非白人)。多变量logistic(二分类变量)和线性(连续变量)回归模型比较了按性别和种族分层的临床住院结果、资源利用和医院成本。结果估计有5,870,482名(调查加权)老年人因跌倒而住院,年发病率从1,108,024上升到1,210,547 (P < 0.001)。与男性相比,女性未经调整的住院死亡率较低(2.5% vs 4.5%, P < 0.001)。经过风险调整后,女性住院死亡率(AOR: 0.59, 95% CI: 57-0.60, P < 0.001)和费用(β = - 1344美元,95% CI: - 1321至- 1267,P < 0.001)较低。粗略分析,非白人患者的住院死亡率更高(3.4% vs 3.2%, P < 0.001)。非白人患者的平均LOS(6.31±7.69天)比白人患者(5.65±5.93天,P < 0.001)更长。风险调整后,非白人患者的住院死亡率高于白人患者(AOR: 1.16, 95% CI: 1.08-1.24, P < 0.001),中位成本较高(β = 2304美元,95% CI: 1897.90-2710.16, P < 0.001)。结论:性别和种族与老年人跌倒住院的临床住院结果和费用差异有关,提示在治疗、康复和获得护理方面存在潜在差异。需要进一步的研究来更好地了解这些差异,并为更公平的护理策略提供信息。

Colorectal cancer with synchronous metastatic disease to the liver represents a particular challenge in multidisciplinary cancer care. Optimal management involves a combination of surgical resection, systemic, regional and/or targeted therapies; however, the order of and timing of specific therapies requires a nuanced understanding of the disease biology including tumor genomics. In the following article, we conducted a narrative review of the literature to critically examine existing data on the impact of tumor genomics in synchronous colorectal liver metastasis management. We provide a qualitative synthesis of the available literature and identify areas of particular interest for investigation moving forward.

结直肠癌伴肝脏同步转移是多学科癌症治疗的一个特殊挑战。最佳治疗包括手术切除、全身、局部和/或靶向治疗的结合;然而,特定治疗的顺序和时机需要对包括肿瘤基因组学在内的疾病生物学有细致入微的了解。在下一篇文章中,我们对文献进行了叙述性回顾,以批判性地检查肿瘤基因组学在同步结直肠癌肝转移治疗中的影响的现有数据。我们提供了一个定性的综合现有文献,并确定了特别感兴趣的领域进行调查。
