Background and aims: There is no consensus on which Lisfranc injuries can be treated non-operatively. The aim of the study was to compare non-operative treatment and open reduction and internal fixation (ORIF) in the treatment of non-displaced Lisfranc injuries.

Materials and methods: This study was a multicenter randomized controlled trial (RCT) conducted at two hospitals in Finland between 19 March 2012, and 20 December 2022, with a target sample size of 60 patients. The primary outcome was Visual Analogue Scale Foot and Ankle (VAS-FA) at 2 years. The secondary outcomes included VAS-FA pain, function, and other complaints subscales and the American Orthopedic Foot & Ankle Society (AOFAS) Midfoot Scale. All outcomes were measured at 6 months, 1 and 2 years.

Results: Altogether 27 patients with computed tomography (CT)-confirmed non-displaced Lisfranc injuries were enrolled in this trial resulting in an underpowered trial. In patients with non-displaced Lisfranc injuries, the mean VAS-FA overall score in the non-operative group was 96.1 [confidence interval (CI): 91.5-100] and 91.8 [86.9-96.7] in the ORIF group at 2 years with no statistically significant difference between the groups (mean between-group difference (MD) 4.3 [CI, -2.4 to 11], Cohen's d = 0.706) in this underpowered RCT.

Conclusion: There was no difference in VAS-FA between non-operative and ORIF in patients with non-displaced Lisfranc injuries, but the trial is underpowered to draw robust conclusions.

Background and objective: Assessing surgical outcomes, notably postoperative complications (PCs), is crucial for healthcare systems. However, reliance on International Classification of Diseases, 10th revision (ICD-10) codes, may be suboptimal. This study aims to compare the accuracy of ICD-10 codes against manual curation of electronic healthcare records (EHRs) for identifying 13 individual PCs and evaluate associated resource utilization.

Methods: EHR data from 11,827 surgical cases across 18 Danish hospitals in November 2021 were analyzed. PCs were identified and extracted through both manual curation and ICD-10 codes. Outcomes such as readmission, admission days, intensive care unit (ICU) stays, reoperations, and radiology procedures were assessed as proxies for resource consumption. Statistical and economic analyses quantified resource utilization and associated costs.

Results: In total, 1047 PCs were found through manual curation and 439 PCs were found through ICD-10 codings. Only 218 of the PCs found through ICD-10 codes were retrieved during manual curation-corresponding to a correct ICD-10 coding of 20.8% of PCs. Patients with PCs experienced significantly higher resource utilization, including a 6.6 times higher readmission rate, 6 additional admission days, 2 extra ICU days, 7.7 times more reoperations. PCs incurred substantial economic costs, with additional admission days alone accounting for €25.5 million annually, over four times higher than estimates from ICD-10 codes.

Conclusions: ICD-10 codes inadequately capture early PCs highlighting the need for improved detection strategies. The actual costs associated with PCs far exceed current estimates, emphasizing the necessity for enhanced monitoring for informed decision-making. In the Danish healthcare system, ICD-10 codes only capture approximately 21% of PCs, making it inadequate for surgical quality monitoring. The actual costs related to PCs, based on study assumptions, are more than four times higher than estimated from current standard. This calls for novel strategies for PC detection to improve healthcare as well as political and financial decision-making.

Background and aims: To investigate whether, alongside aortic dilatation, ascending aortic (AA) elongation is associated with the increased risk for aortic dissection.

Methods: This retrospective study included patients treated for Stanford type A aortic dissection (n = 102) in Kuopio University Hospital between 2009 and 2022, patients with AA dilatation (maximal diameter > 40 mm) (n = 134), and healthy controls (n = 191). AA length and dimensions were measured from aortic computed tomography angiography (CTA) images. AA length was defined as the distance between the aortic annulus and the origin of the brachiocephalic trunk.

Results: After adjusting the AA length to the patients' age, height, body surface area (BSA), sex, and maximal diameter, the dissected aortas were 14 mm longer than in the healthy controls and 5 mm longer than in the dilated non-dissected aortas (p < 0.001). The dilated non-dissected aortas were 8 mm longer than in the healthy controls (p < 0.001). In the dissection cohort, 25/102 (25%) patients had maximal AA diameter < 55 mm and 16/102 (16%) patients had maximal AA diameter ⩾ 55 mm together with AA length > 110 mm. By combining 110 mm AA length and < 55 mm diameter, 58% of the dissection patients would have been identified instead of using solely AA diameter ⩾ 55 mm as a cut-off criterion, based on which only 33% patients met the indication for elective surgery.

Conclusion: AA length seemed to have an association with acute type A dissection, and therefore, it could be an additional tool in identifying patients who may benefit from preventive aortic surgery.[Formula: see text].

Background: Carotid endarterectomy (CEA) carries a risk of perioperative stroke, particularly during carotid cross-clamping. While neurological monitoring is reliable for patients under regional anesthesia, alternative options are needed for those unsuitable for regional anesthesia. Near-infrared spectroscopy (NIRS) is commonly used during CEA, but its diagnostic accuracy varies, particularly under general anesthesia.

Methods: A systematic review with meta-analysis was performed to assess the diagnostic accuracy of intraoperative NIRS in detecting clamp-associated hemodynamic cerebral ischemia in patients under general anesthesia. MEDLINE, Google Scholar, and Web of Science were searched for studies that compared NIRS with the occurrence of immediate or early postoperative neurological deficits in patients undergoing CEA under GA. Meta-regression was performed to explore causes of heterogeneity.

Results: A total of 28 studies involving 5729 patients were included. The results show that NIRS has a summary sensitivity of 47.5% and a summary specificity of 90.3% in diagnosing clamp-associated cerebral ischemia under general anesthesia, with an area under the ROC curve (AUC-ROC) of 0.85. The presence of a contralateral carotid occlusion (CCO) increased summary sensitivity while smoking history the presence of CCO and smoking history decreased summary specificity. For postoperative stroke prediction, NIRS has a summary sensitivity of 49.5% and summary specificity of 88.5%, with an AUC-ROC of 0.85.

Conclusions: NIRS is a specific but not highly sensitive tool for detecting cerebral ischemia during CEA, and its use in combination with more sensitive neuromonitoring methods is recommended, in order to guide intraoperative neuroprotective strategies.

Frailty is a common phenomenon in older adult population and associated with an elevated risk of adverse health outcomes. Recent studies have demonstrated that patients with frailty undergoing surgery had a significantly higher morbidity and mortality compared to those without frailty. This is particularly important in patients with cancer because the prevalence of frailty is persistently high across a spectrum of primary cancers. Identifying frailty in oncological patients undergoing surgery may provide an important preoperative intervention opportunity to mitigate operative risks. In this review, we provide an overview of frailty and its association with other geriatric syndromes. We will also review the impact of frailty on postoperative outcomes focusing on the field of surgical oncology. We then describe currently available tools to objectively measure frailty to provide clinicians with various practical tools that may be adopted in their clinical practice. Finally, we will describe potential interventional programs, including the recently introduced Geriatric Surgery Verification program by the American College of Surgeons, that may be institutionally adopted to mitigate postoperative complications and improve meeting patient-centered goals in the frail patient population.

Background and aims: Evidence suggests that female surgeons achieve comparable or even more favorable outcomes than male surgeons. It is currently unclear what factors contribute to these potential differences. Possible explanations might be differences in personality traits, communication style, attitude, and risk-taking behavior. This cross-sectional study aimed to examine disparities in personality traits between male and female general surgeons in Sweden.

Methods: The research was conducted as a cross-sectional study of personality traits. Between August 29, 2022, and December 15, 2023, Swedish specialists in general surgery were invited to participate in an online survey. The survey, assessed with the Big Five Inventory, collected information on self-reported surgeon gender, years in practice, employment data, and differences in personality traits.

Results: The analysis encompassed responses from 223 Swedish general surgeons: 121 (54%) males and 102 (46%) females. In contrast to female surgeons, male surgeons were older and had longer surgical experience. A higher proportion of male surgeons were employed in rural hospitals. Higher mean scores were observed in all personality traits among female surgeons. The adjusted analysis showed significantly higher scores for conscientiousness (p < 0.001), extraversion (p < 0.001), agreeableness (p = 0.006), and neuroticism (p < 0.001); however, no such change was observed for openness.

Conclusion: This cross-sectional study demonstrates that Swedish female and male surgeons differ in personality traits. The implications of these results could lead to a deeper understanding of the variations in surgical outcomes based on the gender of the surgeon.

Background: Tailoring surgical treatment is mandatory to optimize outcomes in chronic pancreatitis. Total pancreatectomy (TP) offers pain relief in a subset of patients. TP with islet autotransplantation (IAT) has the potential to reduce the burden of postsurgical diabetes. We present the first Scandinavian prospective study assessing outcomes following total pancreatectomy and islet autotransplantation (TPIAT) in chronic pancreatitis. Our aim was to assess short- and long-term outcomes following implementation of a nationwide program of TPIAT at a tertiary reference center for pancreatic surgery in Norway.

Methods: A prospective, observational single-center study enrolling consecutive patients undergoing TPIAT for chronic pancreatitis at Oslo University Hospital. The selection of potential candidates for TPIAT was based on discussions at multidisciplinary team (MDT) meetings, focusing on tailored surgery in chronic pancreatitis. Patients were finally evaluated in a dedicated TPIAT team. The outcome measures included pain relief, quality of life (QoL) assessed by EORTC QLQ-C30, complications, and glycemic control.

Results: Between August 2017 and November 2022, 15 patients underwent TPIAT. The follow-up rate was 87% with a median follow-up of 26 months (range = 14-65). Pain relief was achieved in 92%. EORTC QLQ-C30 analysis revealed clinically significant improvements in 28 of 30 domains, particularly in pain and role- and social-functioning. The Clavien-Dindo ≥IIIa complications occurred in one patient. There was no 90 days mortality. All patients maintained C-peptide positivity, although none of the patients reached insulin independence.

Conclusion: TPIAT was as a safe and effective treatment for a selected group of patients with chronic pancreatitis, providing substantial pain relief and enhanced QoL. Islet autotransplantation prevented complete insulin deficiency, reducing diabetes severity postpancreatectomy. Dedicated chronic pancreatitis MDT meetings were key factor in the success of the program.

International and national guidelines recommend metabolic and bariatric surgery (MBS) as a treatment option for adolescents with severe obesity, but few countries offer MBS to adolescents in routine clinical care. This narrative review summarizes existing adolescent MBS guidelines and the available underpinning evidence. Two randomized trials and additional prospective studies have demonstrated efficacy and safety in adolescent MBS, and the health benefits appear to be similar or superior to outcomes in adults. However, there are specific challenges regarding the intervention during adolescence related to decision-making capacity and a peak in risk-taking behavior. Adolescents with severe obesity have-as a group-a mental health vulnerability, and specific nutritional concerns need to be addressed in relation to MBS. This review also describes how study findings can be translated into clinical care. We use Sweden as an example, where the National Board of Health and Welfare recommends MBS for selected adolescents with severe obesity aged 15 years or older. We present practical advice for implementing and integrating MBS in adolescents in the framework of multidisciplinary pediatric and adolescent care for obesity.
