Change in Lumbar Lordosis after Decompressive Surgery in Lumbar Spinal Stenosis Patients and Associations with Patient Related Outcomes 2 Years after Surgery. Radiological and Clinical Results from the NORDSTEN Spinal Stenosis Trial.

A prospective cohort study. The aim was to investigate changes in lumbar lordosis (LL) and its association to changes in patient reported outcome measures (PROMs) after decompressive surgery for lumbar spinal stenosis (LSS). Few studies have addressed change in LL after decompression surgery for LSS in relation to outcomes. Pre- and postoperative data from 310 patients having standing x-ray both before and 2 years after surgery were included. The patients were grouped based on the change in LL preoperatively to 2 years after surgery; group 1: <5 degrees (n=196), group 2: ≥5 <10 degrees (n=55) or group 3: ≥10 degrees (n=59) of change in LL. The changes in function, disability and pain were assessed by the Oswestry Disability Index (ODI), Numeric Rating Scale (NRS), and the Zurich claudication questionnaire (ZCQ). The three groups were compared regarding baseline variables using the ANOVA test for continuous variables and the chi-square test for categorical variables. The groups were further compared with a likelihood ratio test in relation to changes in PROMs 2 year after surgery and outcomes were adjusted for respective baseline PROMs, age, sex, smoking, BMI, Schizas and Pfirrmann scores. LL was significantly changed at group level 2 years after surgery with a mean difference of 2.2 (SD 9.4) degrees ( P =0.001). The three LL change groups did not show any significant differences in patient characteristics, function, disability, and pain at baseline. The two groups with a change of more than 5 degrees in LL 2 year after surgery (group 2 and 3) had significantly greater improvements in ODI ( P =0.022) and ZCQ function ( P =0.016) in the adjusted analyses, but was not significant for back and leg pain. Changed LL after decompressive surgery for LSS was associated with improved ODI and physical function.

Delayed gastric emptying after laparoscopic pancreaticoduodenectomy: a single-center experience of 827 cases

BackgroundDelayed gastric emptying (DGE) commonly occurs after pancreaticoduodenectomy (PD). Risk factors for DGE have been reported in open PD but are rarely reported in laparoscopic PD (LPD). This study was designed to evaluate the perioperative risk factors for DGE and secondary DGE after LPD in a single center.MethodsThis retrospective cohort study included patients who underwent LPD between October 2014 and April 2023. Demographic data, preoperative, intraoperative, and postoperative data were collected. The risk factors for DGE and secondary DGE were analyzed.ResultsA total of 827 consecutive patients underwent LPD. One hundred and forty-two patients (17.2%) developed DGE of any type. Sixty-five patients (7.9%) had type A, 62 (7.5%) had type B, and the remaining 15 (1.8%) had type C DGE. Preoperative biliary drainage (p = 0.032), blood loss (p = 0.014), and 90-day any major complication with Dindo-Clavien score ≥ III (p < 0.001) were independent significant risk factors for DGE. Seventy-six (53.5%) patients were diagnosed with primary DGE, whereas 66 (46.5%) patients had DGE secondary to concomitant complications. Higher body mass index, soft pancreatic texture, and perioperative transfusion were independent risk factors for secondary DGE. Hospital stay and drainage tube removal time were significantly longer in the DGE and secondary DGE groups.ConclusionIdentifying patients at an increased risk of DGE and secondary DGE can be used to intervene earlier, avoid potential risk factors, and make more informed clinical decisions to shorten the duration of perioperative management.

Robotic-Assisted Management of Ureteral Complications in Post-Renal Transplant Patients: A Case Series and Literature Review.

Introduction: Urologic complications are thought to be the most common surgical complication of renal transplantation. Ureteral pathology, including stenosis, urine leak, and vesicoureteral reflux, predominates. Although endourologic and interventional radiological management may be utilized, failure rates remain relatively high and surgical reconstruction remains the definitive management. Robotic ureteral reconstruction has been demonstrated to provide patient benefit in nontransplant populations, but the literature on transplant reconstruction is very limited. This study reports an additional series of patients with a focus on surgical technique, as well as reviews the available evidence for robotic reconstruction for post-transplant ureteral complications. Methods: All institutional patients undergoing robotic-assisted reconstruction for post-transplant ureteral complications for the years 2019-2022 were included. Intra- and postoperative variables, patient demographics, and follow-up data were obtained retrospectively from parsing of patient records. Statistics were tabulated descriptively. Results: Eleven patients underwent ureteral reconstruction. Of the 11, 9 (81%) were male with a mean age of 51.9 years (16-70) and BMI of 33.8 (24.3-49.1). The most common (10/11) indication for reconstruction was stricture; the most common (10/11) technique used was Lich-Gregoir reimplantation. Mean operative time was 288 minutes (143-500). There were no intra- or immediate postoperative complications. Median length of stay was 2 days (1-22). There were two incidences of mortality at 2 and 5 months postoperatively unrelated to surgery. There were four readmissions within 30 days, three for urinary tract infection (UTI) and one for a pelvic abscess which required washout. The remainder of the cohort has been followed for a mean of 14.6 months (6-41) without any incidences of graft loss or recurrence of ureteral pathology. Conclusions: Robotic-assisted ureteral reconstruction is a technically challenging but highly feasible technique that may provide the benefits of minimally invasive surgery while still allowing definitive reconstruction. Centers with extensive robotic capabilities should consider the technique.

Analysis of the 1-year efficacy of four different surgical methods for treating Chinese super obese (BMI ≥ 50 kg/m2) patients

This study aimed to retrospectively analyze the perioperative and postoperative follow-up data of patients with super obesity who had undergone RYGB, SG, BPD/DS, and SADI-S. A retrospective observational study was conducted to analyze the perioperative and postoperative follow-up data of 60 patients with super obesity who had undergone bariatric surgery. A total of 34 men and 26 women were included in this study. The participants had an average preoperative BMI of 53.81 ± 3.25 kg/m2. The body weight and BMI of all four patient groups decreased significantly at 3, 6, and 12 months postoperatively compared with the preoperative values. Additionally, the TWL (%) and EWL (%) of all four groups increased gradually over the same period. Compared with the preoperative values, the systolic and diastolic blood pressure, glycosylated hemoglobin, uric acid, triglycerides, and total cholesterol decreased to varying degrees in the four groups 1 year postoperatively. RYGB, SG, BPD/DS, and SADI-S are all safe and effective in treating super obese patients and improving their metabolic diseases to a certain extent.

Prediction of ATFM impact for individual flights: A machine learning approach

Air Traffic Flow Management regulations consist of issuing pre-departure ground delays to deal with demand-capacity imbalances in the airspace, smoothing out the demand at congested infrastructures. This results in discrepancies between the initially planned and executed (regulated) flights, negatively impacting operational efficiency and economic performance. To mitigate downstream effects, airspace users need to assess the severity and impact of these regulations when defining their operational plan. It is crucial to anticipate these potential network issues and plan for mitigation measures during the pre-tactical phase (the day before operations (D−1)). This article presents four independent machine learning models to estimate the impact of Air Traffic Flow Management regulations for individual flights during this pre-tactical phase. An integrated view is proposed to combine the results of the different models, displaying the appropriate level of information. Two models are designed to provide information about the probability of a given flight being affected by Air Traffic Flow Management regulations and the reason for this regulation (airport or airspace congestion). These models have reported accuracy levels between 82% and 87%. The remaining models estimate the impact of the delay (amount of Air Traffic Flow Management delay issued to the flight if regulated), with a Mean Absolute Error of 9.5 min when predicting this amount of delay. The SHapely Additive exPlanations analysis is used to identify the most important factors for detecting Air Traffic Flow Management regulations for individual flights during the pre-tactical phase from a data-driven perspective. An integrated view is proposed to create a system which combines the results of the four different models, displaying the appropriate level of information and avoiding an overload of information. Finally, the results are compared against models considering only static or post-operational data.

Early outcomes of the oxford unicompartmental knee arthroplasty: 140 cases from a single institute in Taiwan.

The clinical and radiologic outcomes of the Oxford Unicompartmental Knee Arthroplasty utilizing Microplasty® instrumentation have not been extensively investigated in Taiwanese patients. Despite the efficacy of this treatment for unicompartmental knee diseases, its specific impact on this population remains unknown. We retrospectively analyzed prospectively collected data of patients who underwent OUKA with MP between 2018 and 2021, including demographic information, component position, pre- and postoperative knee range of motion (ROM), numeric rating scale (NRS), and 2011 Knee Society Score-functional activity score (2011 KSS-FAS). We compared pre- and postoperative data and analyzed the correlation between clinical and radiographic outcomes. Among 140 patients with an average age of 66.8 years, predominantly female, the majority exhibited components that fell within the radiographically acceptable tolerance ranges. The mean 2.5-year follow-up revealed significant improvements in knee ROM from 102.6° ± 12.9° to 127.3° ± 9.8° (p < 0.05), pain reduction from 7.7 ± 0.8 to 0.4 ± 0.7 (p < 0.001), and KSS-FAS from 30.7 ± 10.5 to 94.3 ± 5.2 (p < 0.001). Notably, a tibial component medial overhang within tolerance predicted shorter hospital stays, and a higher preoperative KSS correlated with lower postoperative NRS. No independent variables were identified as predictors of a higher postoperative KSS. Our study on OUKA with MP in Taiwanese patients reveals promising early clinical and radiographic outcomes. Tibial component medial overhang <3 mm is associated with shorter hospital stays, and a higher preoperative KSS predicts lower NRS at 1 year postoperatively.

Mesentery-Sparing Technique: a New Intracorporeal Approach for Urinary Diversion in Robot-Assisted Radical Cystectomy.

Robotic-assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) is associated with significant morbidity and mortality. We present an alternative technique that preserves the complete mesenteric vascularization during the isolation of the intestinal segment used in ICUD, including distal vessels. This approach aims to minimize the risk of ischemia in both the ileal anastomosis and the isolated loop at the diversion site. This cohort study included 31 patients, both male and female, who underwent RARC with ICUD from February 2018 to November 2023, performed by a single surgeon. Intraoperative and postoperative complications data were retrieved for analysis, employing our proposed mesentery-sparing technique in all cases. The primary endpoint was the incidence of intraoperative and postoperative complications directly attributable to the mesentery-sparing approach in ICUD. Secondary endpoints included other postoperative variables not directly related to mesentery preservation, such as the incidence of postoperative ileus requiring parenteral nutrition and the duration of hospitalization. None of the patients experienced intraoperative or postoperative complications directly related to mesentery-sparing, such as intestinal fistulae or internal hernias. The median duration of hospitalization was 6 days, and postoperative ileus necessitating total parenteral nutrition occurred in 19% of the patients. Minor complications (Clavien-Dindo grades I-II) accounted for 27.6% of the cases and major complications (grades III-V) accounted for 20.6%. The mesentery-sparing technique outlined herein offers an alternative method for preserving the vascularization of intestinal segments and reducing the risk of intestinal complications in ICUD during RARC.

Safety and Efficacy of Surgical Implantation of Intrathecal Drug Delivery Pumps in Patients With Cancer With Refractory Pain.

Pain management in patients with cancer is a critical issue in oncology palliative care as clinicians aim to enhance quality of life and mitigate suffering. Most patients with cancer experience cancer-related pain, and 30%-40% of patients experience intractable pain despite maximal medical therapy. Intrathecal pain pumps (ITPs) have emerged as an option for achieving pain control in patients with cancer. Owing to the potential benefits of ITPs, we sought to study the long-term outcomes of this form of pain management at a cancer center. We retrospectively reviewed medical records of all adult patients with cancer who underwent ITP placement at a tertiary comprehensive cancer center between 2013 and 2021. Baseline characteristics, preoperative and postoperative pain control, and postoperative complication rate data were collected. A total of 193 patients were included. We found that the average Numerical Rating Scale (NRS) score decreased significantly by 4.08 points (SD = 2.13, P < .01), from an average NRS of 7.38 (SD = 1.64) to an average NRS of 3.27 (SD = 1.66). Of 185 patients with preoperative and follow-up NRS pain scores, all but 9 experienced a decrease in NRS (95.1%). The median overall survival from time of pump placement was 3.62 months (95% CI: 2.73-4.54). A total of 42 adverse events in 33 patients were reported during the study period. The 1-year cumulative incidence of any complication was 15.6% (95% CI: 10.9%-21.1%) and for severe complication was 5.7% (95% CI: 3.0%-9.7%). Eleven patients required reoperation during the study period, with a 1-year cumulative incidence of 4.2% (95% CI: 2.0%-7.7%). Our study demonstrates that ITP implantation for the treatment of cancer-related pain is a safe and effective method of pain palliation with a low complication rate. Future prospective studies are required to determine the optimal timing of ITP implantation.

Abstract PO5-22-08: Comparison of long-term oncological outcomes in young women with breast cancer between BRCA-mutation carriers versus non-carriers: How genetic risk factors and tumor characteristics influence the prognosis

Abstract Objectives and rationale: Breast cancer (BC) arising at a young age is relatively uncommon; however, approximately 6 to 10% of women diagnosed with BC are younger than the age 40. This subgroup of young women presents different risk factors, tumor biology, and clinical outcomes. Moreover, the interpretation of the effects of inherited genetic factors on the prognosis of young patients with BC remains a subject of debate. The primary aim of this study was to evaluate the characteristics of young patients with BC and to compare the long-term oncological results between BRCA-mutation carriers and non-carriers. We retrospectively reviewed all the consecutive young (≤ 40 years old) BC patients treated at the Breast Unit of IRCCS Humanitas Research Hospital (Milan, Italy). All young patients underwent BRCA-mutation analysis. For further analysis young BC patients were divided into two groups: BRCA-mutation carriers versus non-carriers. Tumor, surgical treatment, and post-operative data were compared between the two groups. Primary end-points were: disease-free survival (DFS), distant disease-free survival (DDFS), and overall survival (OS). The Kaplan-Meier method was used to generate the recurrence and survival curves. Multivariate analyses were performed using the Cox proportional hazards model to identify independent risk and protective factors for DFS, DDFS, and OS. Results: The characteristics of 63 young BC patients with BRCA-mutation were compared with 339 young BC patients without BRCA-mutation. BRCA-mutation carriers tend to be younger (60.3% versus 34.8% if age ≤ 35 years, odds ratio (OR) = 17.699, 95% confidence interval (95%CI) = 33.871-35.568, p = 0.001) and present more aggressive tumors (66.7% versus 40.7% if G3, OR = 17.119, 95%CI = 2.549-2.828, p = 0.001; 57.2% versus 12.4% if biological subtype triple negative, OR = 52.727, 95%CI = 2.042-2.417, p = 0.001; 73.0% versus 39.2% if Ki67 ≥ 25%, OR = 58.981, 95%CI = 47.135-58.505, p = 0.001). Young BC patients without BRCA-mutation presented significantly better long-term oncological results in terms of DFS, DDFS, and OS compared with young BRCA-mutation carriers (10-years DFS rate 91.1% versus 58.1%, p &amp;lt; 0.001; 10-year DDFS rate 91.2% versus 76.1%, p = 0.003; 10-year OS rate 98.0% versus 87.8%, p = 0.002, respectively). Neo-adjuvant chemotherapy was found to be an independent protective factor for OS in young BRCA-mutated BC patients (hazard radio = 14.885, 95%CI = 2.343-94.566, p = 0.004). Conclusions: Breast cancer is more likely to present at a younger age (≤ 35 years) and with more aggressive characteristics (G3, triple negative, Ki67 ≥ 25%) in patients with BRCA-mutation compared with their non-mutated counterpart. Young BRCA-mutation carriers show a poorer prognosis in terms of recurrence and survival compared with non-carriers. The implementation of neo-adjuvant chemotherapy may improve survival in young BC patients with BRCA-mutation.

The Evolution of Enhanced Recovery After Surgery: Assessing the Clinical Benefits of Developments Within Enhanced Recovery After Surgery Protocols in Adult Cervical Deformity Surgery.

Retrospective cohort. To investigate the impact of evolving Enhanced Recovery After Surgery (ERAS) protocols on outcomes after cervical deformity (CD) surgery. ERAS can help accelerate patient recovery and assist hospitals in maximizing the incentives of bundled payment models while maintaining high-quality patient care. However, there remains a paucity of literature assessing how developments have impacted outcomes after adult CD surgery. Patients with operative CD 18 years or older with pre-baseline and 2 years (2Y) postoperative data, who underwent ERAS protocols, were stratified by increasing implantation of ERAS components: (1) early (multimodal pain program), (2) intermediate (early protocol + paraspinal blocks, early ambulation), and (3) late (early/intermediate protocols + comprehensive prehabilitation). Differences in demographics, clinical outcomes, radiographic alignment targets, perioperative factors, and complication rates were assessed through Bonferroni-adjusted means comparison analysis. A total of 131 patients were included (59.4 ± 11.7 y, 45% females, 28.8 ± 6.0 kg/m 2 ). Of these patients, 38.9% were considered "early," 36.6% were "intermediate," and 24.4% were "late." Perioperatively, rates of intraoperative complications were lower in the late group ( P = 0.036). Postoperatively, discharge disposition differed significantly between cohorts, with late patients more likely to be discharged to home versus early or intermediate cohorts [χ 2 (2) = 37.973, P < 0.001]. In terms of postoperative disability recovery, intermediate and late patients demonstrated incrementally improved 6 W modified Japanese Orthopedic Association scores ( P = 0.004), and late patients maintained significantly higher mean Euro-QOL 5-Dimension Questionnaire and modified Japanese Orthopedic Association scores by 1 year ( P < 0.001, P = 0.026). By 2Y, cohorts demonstrated incrementally increasing SWAL-QOL scores (all domains P < 0.028) domain scores versus early or intermediate cohorts. By 2Y, incrementally decreasing reoperation was observed in early versus intermediate versus late cohorts ( P = 0.034). The present study demonstrates that patients enrolled in an evolving ERAS program demonstrate incremental improvement in preoperative optimization and candidate selection, greater likelihood of discharge to home, decreased postoperative disability and dysphasia burden, and decreased likelihood of intraoperative complications and reoperation rates.

COLPOSACROPEXIA ROBÓTICA PARA EL TRATAMIENTO DEL PROLAPSO DE ÓRGANOS PÉLVICOS EN MUJERES DE EDAD AVANZADA: ANÁLISIS COMPARATIVO DE LA SEGURIDAD Y EFICACIA FRENTE A MUJERES JÓVENES

INTRODUCTION: Pelvic organ prolapse is a condition with high prevalence in elderly women. With increasing life expectancy and a desire for improved quality of life, a rise in the frequency of surgical treatments for these women is anticipated. The aim is to compare complication, success, and satisfaction rates among elderly patients (aged >70 years) in comparison to younger women undergoing robotic sacrocolpopexy, thereby assessing the safety and efficacy of this surgery in this group of patients.METHOD: A prospective observational comparative study of 123 robotic sacrocolpopexies conducted between December 2016 and June 2022. Patients were stratified by age (cutoff point: 70 years). Baseline characteristics, type, and grade of prolapse, intra and postoperative data, complications, functional and anatomical outcomes, and satisfaction levels were collected.RESULTS: Among the 123 patients, 62.6% were under 70 years old, while 37.4% were 70 years or older, exhibiting similar baseline characteristics, prolapse grade, and type. The percentages of intraoperative (6.5%) and postoperative complications (4.4-9%) were comparable in both age groups. Furthermore, success and satisfaction rates exceeded 90%, with no significant differences between women under and over 70 years during a two-year follow-up.CONCLUSION: Robotic sacrocolpopexy is at least as effective and safe in women aged 70 years or older as in younger individuals, with no higher rates of intra and postoperative complications and similar rates of anatomical and subjective success.

The safety and feasibility Assessment of Overlap Esophagojejunostomy with Self-pulling and Latter Transection Technique in Totally Laparoscopic Total Gastrectomy

BackgroundThis study presents an innovative technique in totally laparoscopic total gastrectomy (TLTG) for Overlap esophagojejunostomy, termed self-pulling and latter transection (Overlap SPLT). It evaluates the effectiveness and short-term outcomes of this novel method through a comparative analysis with the established functional end-to-end esophagojejunostomy incorporating self-pulling and latter transection (FETE SPLT). MethodsFrom September 2018 to September 2023, this study enrolled 68 gastric cancer patients who underwent totally laparoscopic total gastrectomy (TLTG) with Overlap SPLT anastomosis and 120 patients who underwent TLTG with FETE SPLT anastomosis. Clinicopathological characteristics, surgical and postoperative outcomes data for Overlap SPLT cases were gathered and retrospectively compared with those from FETE SPLT TLTG to evaluate the effectiveness and clinical safety. ResultsThe duration of anastomosis for Overlap SPLT was 25.3 ± 7.4minutes, significantly longer than that for the FETE SPLT (18.1 ± 4.0minutes, P = 0.031). Perioperatively, one anastomosis-related complication occurred in each group, but this did not constitute a statistically significant difference (P = 0.682). No statistically significant differences were found between the two groups in terms of operative time, postoperative hospital stay, operative cost, surgical margins, or number of lymph nodes removed. Postoperative morbidity rates were similar between the groups (4.4% vs. 5.8%, P = 0.676). ConclusionThe Overlap SPLT technique is regarded as a safe and feasible method for anastomosis. There were no apparent differences in complications between Overlap SPLT and FETE SPLT, but Overlap SPLT costed one additional stapler cartridge and required a longer duration.

Acetabular Distraction: Promising 5-Year Outcomes for the Treatment of Chronic Pelvic Discontinuity

Acetabular Distraction: Promising 5-Year Outcomes for the Treatment of Chronic Pelvic Discontinuity

The application of a single-hand-operated hepatic pedicle clamping clamp in laparoscopic hepatectomy.

In this paper, a single-hand-operated hepatic pedicle clamp was introduced, and its application value in laparoscopic liver tumor resection was preliminarily discussed. The clinical data of 67 patients who underwent laparoscopic liver tumor resection at the First Affiliated Hospital of Wannan Medical College from March 2019 to October 2023 were retrospectively analyzed. The Pringle maneuver was performed with a hepatic pedicle clamp during the operation. The preoperative, intraoperative and postoperative clinical data were observed and recorded. Sixty-seven patients had a median block number, block time, intraoperative blood loss, and postoperative length of hospital stay of 4, 55 min, 400 ml, and 7 days, respectively. The average operation time was 304.9±118.4 min, the time required for each block was 3.2±2.4 s, and the time required for each removed block was 2.6±0.7 s.None of the patients developed portal vein thrombosis or hepatic artery aneurysm formation. The hepatic pedicle clamping clamp is simple to use in laparoscopic hepatectomy, optimizes the operation process, and has a reliable blocking effect. It is recommended for clinical application.

Patient Satisfaction and Healthcare Utilization with the Transition to Virtual Care in a Multidisciplinary Bariatric Program.

The COVID-19 pandemic saw an acceleration in virtual-visits (VV) for healthcare delivery. However, the impact of virtual care in metabolic/bariatric surgery (MBS) programs is not well described. Appointment data from three time-points: pre-pandemic (1/1/19-3/15/20, n = 19,290), pandemic (3/16/20-10/31/21, n = 29,459) and current-state (11/1/21-12/31/2022, n = 24,270) was retrieved in our multi-hospital ambulatory MBS program. Appointments were grouped by health care provider (HCP) (MD, dietician, and psychologist) and type (VV and in-person). Surveys assessing patient satisfaction were distributed electronically. All pre-op and post-op appointment data was analyzed for the time-points above. Appointment completion rates and patient reported preferences were described. Our data showed an increase in scheduled VV from 0.5% for all HCP visits to 81% during the pandemic and a current VV visit of 77%. The number of completed VV increased for all HCPs, most prominently for dieticians. Parallel to this, the percentage of no-show visits also improved for all HCP, with MDs having the lowest no-show rate currently. Survey data revealed 89% of patients experience added benefits with VV and > 90% reported their VV experience as very good. VV were preferred over in-person visits for psychologists and dietitians (> 61%), but the majority preferred to see MDs in-person (70%). Our findings reveal significant changes in healthcare utilization trends since the transition to virtual care. While overall satisfaction with virtual care is high, most patients prefer in-person visits with MDs. Thus, multi-disciplinary MBS care can be performed effectively using a hybrid model to ensure efficient distribution of resources.

Enhanced recovery urinary protocol for patients undergoing hip surgery: a quasi-experimental study.

Postoperative urinary retention (POUR) is a common complication after hip surgery. The enhanced recovery urinary protocol (ERUP) is a tool that employs several perioperative strategies to facilitate optimal conditions for surgery and recovery. The aim of this study was to evaluate the effect of ERUP on POUR in patients undergoing hip surgery. A controlled pre- and post-quasi-experimental study was conducted. Data was collected between May 2018 and January 2019 at the orthopedic department of one of the largest teaching hospitals affiliated with Menoufia University in Egypt. A convenience sample of 100 Egyptian patients (of both genders) undergoing elective hip surgery was equally allocated into two groups. The control group (n = 50) was given traditional routine perioperative nursing care, while the intervention group (n = 50) was subjected to ERUP. Data was collected from socio-demographic, medical, and surgical data sheets, preoperative medication assessment sheets, postoperative data sheets, and fluid balance charts. ERUP application significantly reduced the length of hospital stay and the incidence of POUR in the intervention group. Implementation of the ERUP is recommended for patients undergoing hip surgery, as it has a significantly positive effect on reducing the incidence of POUR.

Клапанозбережне протезування кореня аорти: результати операції Девіда І

The aim – to determine the long-term results and quality of life of patients who underwent David І valve-sparing operation.Materials and methods. The one-center study included 53 patients who underwent planned and urgent David I procedure (valve-sparing replacement of the aortic root and ascending aorta) from 2015 to 2023. The mean age of the 53 patients (among them, 47 (88.68 %) males) was 49.11 ± 1.54 years. We analyzed basic characteristics of the patients, intraoperative and postoperative data. The quality of life was assessed before and in the long-term period after operations by the Medical Outcomes Study Short Form 36 (MOS SF-36) questionnaire.Results and discussion. An average duration of the follow-up period was 2.59 ± 0.27 years ranging from 1.0 to 9.0 years. Overall in-hospital mortality and 30-day mortality was 1.89 % (n 1). Estimated 5-year survival rate was 95.7 ± 1.45 % for all patients. The average duration of the operations was 291.23 ± 12.67 minutes, the total duration of artificial blood circulation was 170.28 ± 8.77 minutes, aorta clamping time – 122.02 ± 5.92 minutes. The mean duration of stay in the hospital was 13.81 ± 0.54 days, intensive care unit – 2.94 ± 0.03 days. The number of patients extubated up to 8 hours after surgery was 48 patients (90.57 %). The performed operation significantly improved the indicators. Patients positively perceived the information about the absence of an artificial heart valve and need of concomitant use of anticoagulants. The patients had a good psycho-social component, which probably affected the assessment of other scales.Conclusions. Patients after David I operation have a low overall in-hospital mortality and 30-day mortality, with a short period of time in intensive care unit and hospital at all. Long-term results in indicator of 5-year survival are excellent. The operation significantly improves quality of life parameters.

Robotic thymectomy in thymic tumors: a multicenter, nation-wide study.

Robotic thymectomy has been suggested and considered technically feasible for thymic tumors. However, because of small-sample series and the lack of data on long-term results, controversies still exist on surgical and oncological results with this approach. We performed a large national multicenter study sought to evaluate the early and long-term outcomes after robot-assisted thoracoscopic thymectomy in thymic epithelial tumors. All patients with thymic epithelial tumors operated through a robotic thoracoscopic approach between 2002 and 2022 from 15 Italian centers were enrolled. Demographic characteristics, clinical, intraoperative, postoperative, pathological and follow-up data were retrospectively collected and reviewed. There were 669 patients (307 men and 362 women), 312 (46.6%) of whom had associated myasthenia gravis. Complete thymectomy was performed in 657 (98%) cases and in 57 (8.5%) patients resection of other structures was necessary, with a R0 resection in all but 9 patients (98.6%). Twenty-three patients (3.4%) needed open conversion, but no perioperative mortality occurred. Fifty-one patients (7.7%) had postoperative complications. Median diameter of tumor resected was 4cm (interquartile range 3-5.5cm), and Masaoka stage was stage I in 39.8% of patients, stage II in 56.1%, stage III in 3.5% and stage IV in 0.6%. Thymoma was observed in 90.2% of patients while thymic carcinoma occurred in 2.8% of cases. At the end of the follow-up, only 2 patients died for tumor-related causes. Five and ten-year recurrence rates were 7.4% and 8.3%, respectively. Through the largest collection of robotic thymectomy for thymic epithelial tumors we demonstrated that robot-enhanced thoracoscopic thymectomy is a technically sound and safe procedure with a low complication rate and optimal oncological outcomes.

Short-term lumbar disc and lumbar stability changes of one-hole split endoscope technique treatment of spinal stenosis

ObjectiveInvestigating the early biomechanical effects of the one-hole split endoscope (OSE) technique on lumbar spine after decompression surgery.MethodsA retrospective analysis was conducted on 66 patients with lumbar spinal stenosis (LSS) who underwent OSE technique surgery at the affiliated hospital of Binzhou Medical University from September 2021 to September 2022. The patients had complete postoperative follow-up records. The mean age was (51.73 ± 12.42) years, including 33 males and 33 females. The preoperative and postoperative imaging data were analyzed, including disc height (DH), foraminal height (FH), lumbar lordosis angle (LLA), changes in disc angle, anterior-posterior translation distance, and lumbar intervertebral disc Pfirrmann grading. The visual analogue scale (VAS) was applied to evaluate the severity of preoperative, postoperative day 1, postoperative 3 months, and final follow-up for back and leg pain. The Oswestry Disability Index (ODI) was applied to assess the functionality at all the listed time points. The modified MacNab criteria were applied to evaluate the clinical efficacy at the final follow-up.ResultsIn 66 patients, there were statistically significant differences (p < 0.05) in DH and FH at the affected segments compared to preoperative values, whereas no significant differences (p > 0.05) were found in DH and FH at the adjacent upper segments compared to preoperative values. There was no statistically significant difference in the LLA compared to preoperative values (p > 0.05). Both the affected segments and adjacent upper segments showed statistically significant differences in Pfirrmann grading compared to preoperative values (p < 0.05). There were no statistically significant differences in the changes in disc angle or anterior-posterior translation distance in the affected or adjacent segments compared to preoperative values (p > 0.05). The VAS scores for back and leg pain, as well as the ODI, significantly improved at all postoperative time points compared to preoperative values. Among the comparisons at different time points, the differences were statistically significant (p < 0.05). The clinical efficacy was evaluated at the final follow-up using the modified MacNab criteria, with 51 cases rated as excellent, 8 cases as good, and 7 cases as fair, resulting in an excellent-good rate of 89.39%.ConclusionsThe OSE technique, as a surgical option for decompression in the treatment of LSS, has no significant impact on lumbar spine stability in the early postoperative period. However, it does have some effects on the lumbar intervertebral discs, which may lead to a certain degree of degeneration.
