It is largely unknown how acutely ill surgical patients and their next of kin have perceived the hospital care during the ongoing pandemic. Therefore, we aimed to explore their experiences. Material and methods: We performed 12 interviews with patients who had undergone acute abdominal surgery in a public acute care hospital in Sweden during March to June 2020. In addition, we interviewed 10 of the patients’ next of kin. We analyzed the interviews using content analysis. Results: Our analysis resulted in two themes: “Worries about seeking acute care” and “The surgical care worked adequately, even though the system was overloaded.” The participants experienced that the hospital maintained its functionality during the ongoing pandemic. Both the patients and their next of kin experienced insufficient information by the hospital, especially during the initial acute phase and at discharge, which led to a perceived loss of control. The implemented ban on visitors was found to have had both positive and negative effects for the patients, whereas the next of kin's experiences focused on the difficulties with not being able to visit. Conclusions: Our findings indicate that the challenges of communication with patients and their next of kin are exacerbated during a crisis such as a pandemic. In addition, a ban on visitors might have both positive and negative aspects. Therefore, we propose individualized routines for visits to acute surgical patients when possible.

We hypothesized that risk factors for febrile complications may be identified with data available at the time of initial fever episode and that a significant proportion of patients exists in which additional testing is of minimal utility. Methods: We performed a retrospective case-control study of patients undergoing elective colorectal resection at a single institution between 2015 and 2020 with postoperative fever ≥38.0°C. Febrile patients with a clinically significant fever source requiring a change in management were compared to patients with fever that resolved spontaneously. An additive risk score from 0 to 3 was generated from selected characteristics with P-value <0.001. Multivariable logistic regression was used to model the odds of infection with the risk score entered as a binary variable (0-1 versus 2-3 risk factors). Results: Of 1036 elective colectomy patients, 143 (13.8%) had postoperative fever ≥38.0°C. Among the febrile patients, 27 had a positive evaluation (18.9%). Active smoking status (P = 0.018), time from surgery to fever, fever ≥38.5°C, other vital sign changes, and documented localizing signs/symptoms (all, P < 0.001) were associated with an identifiable source of fever. On multivariable regression, the presence of 2-3 risk factors and fever onset after postoperative day 1 were associated with a positive fever evaluation. Conclusions: Few patients with fever after colectomy required a change in clinical management. Those without multiple risk factors elicited from an interval history and physical exam are unlikely to benefit from additional testing.

This study aimed to explore the effect of dexmedetomidine (DEX) on intestinal barrier function and its mechanism in critically ill patients undergoing gastrointestinal surgery. Methods: Patients undergoing gastrointestinal surgery were randomized into the DEX group (n = 21) or midazolam (MID) group (n = 21). Sufentanil was used for analgesia in both groups. In the DEX group, DEX was loaded (1 μg/kg) before sedation and infused (0.7 μg/kg/h) during sedation. In the MID group, MID was loaded (0.05 mg/kg) before sedation and infused (0.1 mg/kg/h) during sedation. The mean arterial pressure, heart rate, borborygmus resumption time, first defecation time, length of intensive care unit stay, and length of hospital stay were observed. The diamine oxidase (DAO), D-lactate, TNF-α, IL-6, and α7nAChR levels in plasma or hemocytes were detected before the start of sedation (0 h) and after sedation (24 h). Results: No significant differences in age, sex, body mass index, Acute Physiology and Chronic Health Evaluation II and Sequential Organ Failure Assessment scores were noted (P > 0.05). The mean arterial pressure between 0 h and 24 h showed no significant difference between the groups (P > 0.05), but the heart rate was significantly lower in the DEX group (P = 0.042). The borborygmus resumption time was significantly earlier in the DEX group (P = 0.034). The lengths of intensive care unit stay (P = 0.016) and hospital stay (P = 0.031) were significantly shorter in the DEX group. The TNF-α level in the DEX group was lower at 24 h than 0 h. The D-lactate level was significantly lower in the DEX group than the MID group at 24 h (P = 0.016). The expression of α7nAChR in the DEX group was significantly higher at 24 h than 0 h (P < 0.05). Conclusions: DEX maintained intestinal barrier integrity in patients undergoing gastrointestinal surgery through the cholinergic anti-inflammatory pathway.

Whether hemodynamic variability occurs in patients with undiagnosed PPGL undergoing unrelated, non-neuroendocrine, operations is unknown. Methods: We identified patients who underwent non-neuroendocrine surgical procedures up to 5 y before pathologic diagnosis of PPGL. For each PPGL, two non-PPGL patients were matched based on sex, age, type, and year of operation. Electronic medical records were reviewed for intraoperative blood pressures, heart rates, and hemodynamic variability was assessed with range (maximum-minimum), standard deviation, coefficient of variation, and average real variability. Results: Thirty-seven PPGL patients underwent operations preceding the diagnosis of PPGL: 25 pheochromocytomas, 11 paragangliomas, and one metastatic pheochromocytoma. Median interquartile range tumor size at diagnosis was 35 mm (23 to 60). The time from index operation to PPGL diagnosis was ≤12 mo in 21 (56.8%) patients. In 23 (62.2%) patients, the subsequently diagnosed PPGL was functional. Fifteen (40.5%) PPGL and 20 (27.0%) control patients were preoperatively treated for hypertension (P = 0.149). Maximum intraoperative systolic BP was >180 mmHg for 4 (10.8%) PPGL patients and 3 (4.1%) controls (P = 0.219). Two PPGL patients had intraoperative systolic BP >230 mmHg. No significant differences were found with all other measures of intraoperative hemodynamic variability. Similarly, in secondary analysis there was no significant difference in intraoperative hemodynamic variability between biochemically active PPGL and their respective controls. Conclusions: Patients with undiagnosed PPGL undergoing a wide variety of non-neuroendocrine operations had intraoperative hemodynamic variability comparable to non-PPGL patients undergoing the same type of procedures.

However, the relationship between registration and the reporting quality of systematic reviews on surgical interventions remains unclear. Methods: MEDLINE was searched for relevant systematic reviews of randomized controlled trials investigating surgical interventions published in 2020. Data concerning general characteristics and registration information were independently extracted. The reporting quality was evaluated in accordance with pre-established evaluation criteria. Univariate and multivariate linear regression were performed to identify factors associated with improved reporting quality. Results: A total of 135 systematic reviews were analyzed, of which 50 (37%) were registered. Registered systematic reviews achieved a significantly higher compliance rate on all items compared with non-registered reviews. Registered reviews also demonstrated significantly higher proportions of the reporting of seven items. Multivariate regression analysis showed that registration status and funding support were associated with better reporting quality. Conclusions: Although prospective registration associates with higher reporting quality in systematic reviews, the number of prospective registrations remains low. Therefore, prospective registration should be encouraged among authors, peer reviewers, and journal editors, as well as institutions, to enhance the value of systematic reviews in evidence-based surgical practice.
查看更多>>摘要：? 2022 Elsevier Inc.Introduction: The precise mechanism through which excessive tension confers poor outcomes in nerve gap repair is yet to be elucidated. Furthermore, the effect of tension on gene expression in regenerating nerves has not been characterized. This study investigated differential gene expression in transected nerves repaired under high and minimal tension. Methods: Male Lewis rats underwent right sciatic nerve transection with either minimal-tension or high-tension repair. Fourteen weeks postoperatively, segments of the right sciatic nerves were harvested along with equal-length segments from the contralateral, healthy nerve to serve as internal controls (na?ve nerve). Differentially expressed genes (DEGs) and differentially regulated biochemical pathways between the samples were identified. Results: Seventeen animals were studied. The gene expression profiles of na?ve nerve and minimal-tension repair demonstrated minimal within-group variation, whereas that of high-tension repair demonstrated heterogeneity. Relative to na?ve nerve, high-tension repair samples had 4276 DEGs (1941 upregulated and 2335 downregulated) and minimal-tension repair samples had 3305 DEGs (1479 upregulated and 1826 downregulated). High-tension repair samples had 360 DEGs relative to minimal-tension repair samples (68 upregulated and 292 downregulated). Upregulated biological pathways in all repaired nerves included steroid biosynthesis, extracellular matrix–receptor interaction, and ferroptosis. Finally, upregulated pathways in high-tension repair samples relative to minimal-tension repair samples included tumor necrosis factor signaling, interleukin-17 signaling, cytokine-cytokine receptor interaction, and mitogen-activated protein kinase signaling. Conclusions: The improved outcomes achieved with minimal-tension nerve repair may take root in a favorable gene expression profile. Future elucidation of biochemical pathways in nerve regeneration may identify potential therapeutic targets to optimize primary nerve repair outcomes.

Objective: To develop and validate (face, content, response process, and construct) the performance metrics for a robotic dissection task using a chicken model. Methods: In a procedure characterization, we developed the performance metrics (i.e., procedure steps, errors, and critical errors) for a robotic dissection task, using a chicken model. In a modified Delphi panel, 14 experts from four European Union countries agreed on the steps, errors, and critical errors (CEs) of the task. Six experienced surgeons and eight novice urology surgeons performed the robotic dissection task twice on the chicken model. In the Delphi meeting, 100% consensus was reached on five procedure steps, 15 errors and two CEs. Novice surgeons took 20 min to complete the task on trial 1 and 14 min during trial two, whereas experts took 8.2 min and 6.5 min. On average, the Expert Group completed the task 56% faster than the Novice Group and made 46% fewer performance errors. Results: Sensitivity and specificity for procedure errors and time were excellent to good (i.e., 1.0-0.91) but poor (i.e., 0.5) for step metrics. The mean interrater reliability for the assessments by two robotic surgeons was 0.91 (Expert Group inter-rater reliability = 0.92 and Novice Group = 0.9). Conclusions: We report evidence which supports the demonstration of face, content, and construct validity for a standard and replicable basic robotic dissection task on the chicken model.
查看更多>>摘要：? 2022 The Author(s)Introduction: The aging process places the elderly, a worldwide increasing age group, at an increased risk for trauma. This study aims to explore changes over time in admission rates, sociodemographical, clinical, and injury-related data in elderly patients (aged ≥65 y) admitted to the Puerto Rico Trauma Hospital (PRTH) during 2000-2019. Materials and methods: A time-series analysis was conducted. Admission rates were analyzed by fitting an exponential growth curve model. Trends were assessed using the Cochrane-Armitage and Cuzick tests for categorical and continuous data, respectively. Results: Elderly admission rates to the PRTH have shown growth over the past 2 decades, from 6.2 cases per 100 overall admissions in 2000 to 18.2 in 2019. This trend is projected to continue with estimated 24.8 (95% CI: 21.7-27.8) cases per 100 overall admissions in 2023. Trends for mechanisms of injury such as motor vehicle accidents and pedestrians showed a significant decrease, whereas falls presented a clear positive trend, showing an increase from 25.6% in 2000-2004 to 46.2% in 2015-2019. Both Injury Severity Score ≥25 and Glasgow Coma Scale ≤8 declined significantly through time. Finally, in-hospital mortality presented a decreasing trend from 31.7% in 2000-2004 to 21.5% in 2015-2019. Conclusions: Our analysis demonstrates an increase over time in elderly admissions, especially fall-related trauma. Also, it projects this upward trend will continue. This imposes new challenges for PRTH and other healthcare services and is a gateway for the implementation of adapted clinical management.
查看更多>>摘要：? 2022 Elsevier Inc.Introduction: The minimally invasive step-up approach to pancreatitis improves outcomes. Multidisciplinary working groups may best facilitate this approach. However, support for these working groups requires funding. We hypothesize that patients requiring surgical debridement generate sufficient revenue to sustain these working groups. Furthermore, patients selected for surgical debridement by the working group will have a higher rate of percutaneous and endoscopic intervention in adherence to the step-up approach. Methods: We conducted an observational cohort study of all patients with severe acute and/or necrotizing pancreatitis whose care was overseen by our multidisciplinary working group (October 2015 through January 2019). Patient demographics, hospital treatments, and outcomes data were compared between those who underwent surgical debridement and those who did not. Hospital billing data were also collected from those who are undergoing surgical debridement and compared to institutional benchmarks for financial sustainability. Results: A total of 108 patients received care overseen by the working group, 10 of which progressed to surgical debridement. The mean contribution margin percentages for each patient in the surgical debridement group were higher than the threshold value for financial sustainability, 39% (60.34% ± 16.66%; P = 0.004). Patients in the surgical debridement group were more likely to undergo intervention by interventional radiologist (odds ratio, 1.58; P = 0.005). The mortality was higher in the nonsurgical debridement group (odds ratio, 15; P = 0.008). Conclusions: Our multidisciplinary working group delivered step-up care to patients with pancreatitis. Patients requiring surgical debridement generated a significantly positive contribution margin that could be used to help support the costs associated with providing multidisciplinary care.
查看更多>>摘要：? 2022 Elsevier Inc.Introduction: Surgical excision of substernal thyroid goiters (STG) can be challenging while minimizing postoperative morbidity. Postoperative complication rates associated with transcervical and transthoracic approaches (i.e., partial or total sternotomy) for STG compared to multinodular goiters (MNG) limited to the neck (i.e., non-substernal) remains unclear. This study examines postoperative morbidity related to surgical approaches in the removal of STG and MNG. Methods: A retrospective review of prospectively collected data of 988 patients with STG and non-substernal MNG from a single institution between 2010 and 2021 was performed. Patients were stratified by STG and conventional non-substernal MNG limited to the neck excised by transcervical and transthoracic approach. Postoperative complications including neck hematoma requiring return to the operating room, permanent recurrent laryngeal nerve injury and hypocalcemia, and transient or temporary recurrent laryngeal nerve injury and hypocalcemia were identified. Demographics including age, sex, and race, among others, were analyzed. Results: Of the 988 cases, there were 887 (90%) MNG and 101 (10%) STG. Of the STG cohort, 11 (11%) required a partial sternotomy and 4 (4%) required a total sternotomy. Permanent complication rates for non-substernal MNG and STG patients were 1.5% and 0.9%, respectively. Only transient or temporary hypocalcemia rates were statistically different between the STG and MNG cohorts (9.9% versus 3.8%, P < 0.001). Conclusions: Regardless of transcervical or transthoracic approach, postoperative complications associated with the surgical removal of STG are low in the hands of experienced, high-volume thyroid surgeons.
