The clinical application value of mixed reality in robotic laparoscopic partial nephrectomy

PurposeRobot-assisted laparoscopic partial nephrectomy (RAPN) has become a key technology in the treatment of renal tumors. Effective preoperative planning and precise intraoperative navigation are critical to a successful surgical outcome. This study aimed to evaluate the clinical application value of mixed reality (MR) in robotic nephron-sparing partial nephrectomy for patients with renal tumors of different complexity based on the R.E.N.A.L. score.Patients and methodsA retrospective analysis was conducted on 68 eligible patients with renal cancer who underwent RAPN at The Second Affiliated Hospital of Nanchang University from January 2021 to December 2023, with postoperative pathology confirmation. Patients were divided into two groups: the MR group, with 28 cases, and the traditional imaging (control) group, with 40 cases. All patients underwent mid-abdominal CT plain scans and enhancements. The MR group utilized three-dimensional reconstruction of CT data and employed 3D tablets and HoloLens glasses for preoperative discussions, surgical planning, and intraoperative guidance. Collect clinical data and metrics to assess surgical outcomes, as well as evaluate performance in areas such as preoperative discussions, doctor-patient communication, surgical planning, and intraoperative navigation.ResultsCompared to robot-assisted partial nephrectomy in the control group, the MR group experienced a reduction in operation time by approximately 30 min [(135.89 ± 23.494) min vs. (165.00 ± 34.320) min, P< 0.001)] and a decrease in ischemia time by around 2.5 min [(20.36 ± 3.956) min vs. (23.80± 6.889) min, P = 0.02)]. Within the subgroup with a R.E.N.A.L. score of less than 7 points, the MR group only showed a significant reduction in operation time [(134.55 ± 150.190) min vs. (150.19 ± 28.638) min, P = 0.045], with no notable differences in other parameters. For the subgroup with a R.E.N.A.L. score of 7 points or higher, the MR group exhibited shorter operation time [(140.83 ± 25.183) min vs. (195.77 ± 23.080) min, P< 0.001] and reduced warm ischemia time [(21.17 ± 2.714) min vs. (28.85 ± 7.570) min, P = 0.029]. Additionally, there was less estimated blood loss [(53.33 ± 5.164) min vs. (114.62 ± 80.376) min, P = 0.018]. All patients had negative resection margins, indicating equivalent therapeutic outcomes between the two groups.ConclusionIn comparison to traditional RAPN, MR technology demonstrates the ability to decrease operation time and warm ischemia time all the while maintaining equivalent curative outcomes. Additionally, it enhances preoperative discussions, doctor-patient interactions, preoperative strategizing, and intraoperative navigation, particularly excelling in complex renal tumor cases of RAPN, where its benefits are most pronounced.

Extended Reality Applications in Otolaryngology Beyond the Operating Room: A Scoping Review

Objective: Extended reality (XR) has increasing usage in medicine, especially surgical fields, but the scope of applications is largely limited to intraoperative navigation. The aim of this scoping review is to evaluate all the available literature on how XR technologies have been applied to otolaryngology—head and neck surgery (OHNS) beyond the operating room for applications such as patient education and interdisciplinary communication. Review Methods: Using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines, we systematically searched PubMed and Scopus. Studies were reviewed without temporal restriction. Inclusion criteria comprised English-language, peer-review papers or conference abstracts studying XR technologies for non-operative uses such as patient education, physician training, or interdisciplinary preoperative planning in the field of OHNS. Results: Database searching initially identified 1607 records. After filtering for duplicates, screening for relevance, and applying the inclusion criteria, 10 studies were ultimately included. This study identifies gaps in the existing literature and describes future applications and key areas of research. XR is a novel strategy for increasing patients’ comprehension of their procedures and can facilitate improved communication and planning amongst a multidisciplinary surgical team during preoperative discussions. However, the existing literature is small in scale and has low statistical power for demonstrating clinical benefits. Conclusions: More robust studies are required to determine the true value of implementing XR. XR is a promising new technology with potential to advance education and patient care in OHNS. Ongoing research will continue to optimize the use of XR technology, ensuring safe and effective integration into clinical practice.

Surgical Approach and Recurrence Risk in Struma Ovarii: A Retrospective and Systematic Analysis.

Struma ovarii (SO) represents a rare subset of ovarian germ cell tumors, with approximately 5% transforming into malignant SO (MSO). This study retrospectively analyzed clinical data from 23 SO patients treated at the Cancer Hospital of the Chinese Academy of Medical Sciences between January 2013 and December 2023, including 17 benign SO (BSO) and 6 MSO cases. Additionally, a systematic review of 164 cases of MSO confined to the ovary, reported in the literature from 1946 to 2024, was conducted. Data on pathological type, treatment, and prognosis were extracted, and univariate and multivariate Cox regression analyses were performed to identify risk factors for recurrence in stage I MSO. The median age at diagnosis was higher for BSO compared to MSO (58 vs. 42.5 years), with 70.6% of patients being postmenopausal. BSO commonly presented with abdominal distension or mass, with more than half having ascites, while MSO patients were asymptomatic and lacked ascites. Cox regression analyses revealed that ovarian cystectomy was adversely associated with recurrence risk in stage I MSO, likely due to surgically induced capsular rent and potential tumor spillage. Significantly lower recurrence risks were observed in patients who underwent unilateral or bilateral salpingo-oophorectomy (HR = 0.36, P = 0.019; HR = 0.19, P = 0.004, respectively). This study highlights the importance of the surgical approach in the management of stage I MSO. A thorough preoperative discussion of the benefits and risks of different surgical approaches is recommended for patients desiring fertility preservation. Postoperative adjuvant therapy has not been shown to have a significant impact on prognosis. For the treatment of recurrent MSO, selecting appropriate surgical and adjuvant therapeutic strategies is essential to improve the long-term prognosis of MSO patients.

Predictors of symptomatic relief in water vapor thermal therapy for prostatic hyperplasia: 36-month prospective study.

Existing literature lacks an analysis of factors predicting the achievement of minimum clinically important differences (MCID) after water vapor thermal therapy (WVTT) for prostatic hyperplasia. This study aims to identify these predictors over a 36-month post-WVTT period. This prospective single surgeon case series assessed male patients receiving WVTT. Eligibility criteria included being at least 45 years old, having an estimated prostate volume (EPV) of 30-80cc, an International Prostate Symptom Score (IPSS) of 12 points or more, and a maximum urinary flow rate (Qmax) under 16 mL/sec. MCID, representing the smallest symptomatic improvement perceived by patients, was calculated using the distribution-based method, considering half a standard deviation of baseline IPSS scores. Correlation and linear regression analyses assessed MCID attainment. Multivariable logistic regression evaluated MCID achievement, considering multicollinearity, heteroskedasticity, and normality. Of 206 men with a median 29.1-month follow-up (Range: 24-36), 13.6% didn't achieve MCID for IPSS, and 7.2% for QoL scores. Significant hindrances to MCID attainment for IPSS were a large median lobe (> 10mm protrusion) (OR = 3.01, 95% CI: 2.3-3.72), increased median lobe treatments (OR = 1.73, 95% CI: 1.23-2.35), and high preoperative irritative IPSS scores (OR = 1.25, 95% CI: 1.13-1.38). Factors for QoL MCID non-achievement included age over 75 (OR = 1.25, 95% CI: 1.13-1.38), a large median lobe (OR = 1.87, 95% CI: 1.62-2.01), and EPV over 60cc (OR = 1.55, 95% CI: 1.16-1.97). A 6.3% surgical re-intervention rate was noted. The characteristics of the median lobe as well as the severity of lower urinary tract symptoms are crucial for treatment success. These should be integral to preoperative assessments and patient discussions on treatment options.

Anesthesia Providers' Knowledge of Medication Interference with Hormonal Contraception: A Multisite Survey.

Sugammadex, aprepitant, and fosaprepitant are increasingly used perioperatively. These medications may interfere with the effectiveness of hormonal contraception. This study assessed anesthesia providers' use of sugammadex and aprepitant, their knowledge of interactions with hormonal birth control, and patient counseling practices to identify possible knowledge gaps or opportunities for practice improvement. In January 2023, an electronic survey was distributed to all anesthesia providers at Mayo Clinic sites (Mayo Clinic Rochester, Mayo Clinic Arizona, Mayo Clinic Florida, and Mayo Clinic Health System hospitals). The survey included 32 questions assessing providers' use of sugammadex and aprepitant, their knowledge of the medications' interactions with hormonal contraceptives (HC), their perceptions regarding education of these interactions during training, and their perioperative patient counseling practices. The collected data were analyzed using descriptive statistics. A total of 337 of 1092 (31%) providers completed the survey. While almost all respondents (324; 96%) knew that sugammadex may interfere with oral contraceptive effectiveness, only 158 (47%) knew about aprepitant's potential contraceptive interference. Only 176 providers (52%) knew the recommended duration for alternative contraceptive methods after use after sugammadex, and 119 providers (35%) knew the recommended duration after aprepitant exposure. Most respondents considered the interference of these perioperative drugs with HCs to be clinically relevant (sugammadex, 217, 64%; aprepitant, 191, 58%). Despite the common belief that the decision between these medications and alternatives should be shared between provider and patient, most providers reported rarely engaging in such shared decision-making (SDM) in practice. Most providers recognized the need for preoperative discussions on sugammadex (280, 83%) and aprepitant (257, 76%), yet 184 providers (73%) never or rarely discussed contraception use before surgery for aprepitant, and 135 (36%) never or rarely did so for sugammadex. Lastly, many providers believed that the interference between sugammadex, aprepitant, and HC was poorly taught during training. The results of this study highlight the need for increased education and awareness among anesthesia providers regarding drug interactions with HCs during the perioperative period. To facilitate SDM, it is imperative that providers discuss alternative medications and the potential need for additional contraception methods after drug administration and communicate the risks with patients preoperatively to enable informed and SDM. The patient's preferences should be accounted for, especially if they are unwilling or unable to use an alternative contraceptive for 7 to 30 days, thereby avoiding the complexities and burdens of altering birth control methods.

Excision of large median and ulnar nerve schwannomas: a case series

ObjectiveSchwannomas are benign, slow-growing tumors originating from Schwann cells in peripheral nerves, commonly affecting the median and ulnar nerves in the forearm and wrist. Surgical excision is the gold standard treatment. This study presents our treatment strategies and outcomes for large-sized ulnar and median nerve schwannomas at the forearm and wrist level.MethodsFrom 2012 to 2023, we enrolled 15 patients with schwannomas over 2 cm in size in the median or ulnar nerve at the forearm and wrist. The study included 12 patients with median nerve schwannomas (mean age: 61 years) and 3 with ulnar nerve schwannomas (mean age: 68 years), with a mean follow-up of 26.9 months.ResultsAfter surgery, all patients with median nerve schwannomas experienced mild, transient numbness affecting fewer than two digits, resolving within six months without motor deficits. Ulnar nerve schwannoma excision caused mild numbness in two patients, also resolving within six months, but all three developed ulnar claw hand deformity, which persisted but improved at the last follow-up. Despite this, patients were satisfied with the surgery due to relief from severe tingling pain.ConclusionsSchwannomas of the median, ulnar, and other peripheral nerves should be removed by carefully dissecting the connecting nerve fascicles to avoid injury to healthy ones. Sensory deficits may occur but are unlikely to significantly impact quality of life. However, in motor-dominant nerves like the ulnar nerve, there is a risk of significant motor deficits that could affect hand function, though not completely. Therefore, thorough preoperative discussion and consideration of interfascicular nerve grafting are essential.

Is Opioid Consumption Impacted by Study Participation? Maintenance of Fewer Opioid Refills With Reduced Prescription Quantity After Posterior Spinal Fusion in Adolescents With Idiopathic Scoliosis.

Opioid overprescribing can lead to nonmedical opioid use. In a previous prospective study (STUDY), we showed that a standardized protocol involving preoperative education and reduced opioid prescription quantity decreased opioid use in idiopathic scoliosis patients following posterior spinal fusion (PSF). A potential limitation was the Hawthorne effect, where participant behavior changes due to observation. At STUDY conclusion, we continued the reduced opioid prescriptions but discontinued the formal preoperative education. This retrospective study (post-STUDY) assessed if opioid refill requests increased outside of a study setting. Post-STUDY included patients aged 10 to 17 years who underwent PSF for idiopathic scoliosis between January 2022 and December 2023 and were discharged with a prescription of ≤30 oxycodone doses. Patients were excluded if they had previous spine surgery or were discharged with an opioid other than oxycodone. Demographics, perioperative variables, and opioid refill requests were compared with the data from STUDY, in which patients were aware their opioid use would be tracked. Patient-reported outcomes were collected via Scoliosis Research Society-22r (SRS-22r) surveys. The post-STUDY cohort included 67 patients (69% female). The average age at the time of PSF was 13.9 years (range, 11 to 17y). The mean number of levels fused was slightly higher (10.9 vs. 10.0, P=0.04), and intraoperative estimated blood loss was lower (211 vs. 303mL, P<0.01) compared with the STUDY cohort. Demographics, preoperative major curve magnitude, surgery duration, and length of hospital stay were similar. The percentage of patients who requested and received opioid refills between the post-STUDY and STUDY cohorts was also similar [6/67 (9%) vs. 3/49 (6%), P=0.30]. SRS-22r showed improvements in self-image, satisfaction, and mean total score from preoperative to postoperative. Reduced opioid prescriptions did not result in increased opioid refill requests in adolescents undergoing PSF for idiopathic scoliosis outside of a study setting. While formal preoperative discussions about postoperative pain control are important, other factors likely influence opioid use. Further research should explore characteristics that predispose patients to require higher amounts of postoperative opioids. Level III-therapeutic.

Intraoperative Incidental Internal Carotid Artery Injury in Extended Endoscopic Endonasal Approaches—Causes, Prevention, and Management: A Technical Note

AbstractIn spite of good anatomical awareness, the position of internal carotid artery (ICA) can be tricky in an intraoperative setup with disease causing very significant distortion of anatomy and shift of carotid artery and its branches. A 45-year-old gentleman presented with complaints of left hemicranial headache and painless progressive vision loss in both eyes (left more than right) for 8 months. A probable clinico-radiological diagnosis of meningioma was reached. Intraoperatively, bleeding occurred from left side ICA, control of which was achieved using a long gauze piece used as conventional nasal pack with crushed muscle beneath the gauze piece along with abdominal fat, which was further reinforced with Surgicel. The parasellar ICA is the most common segment injured. Dehiscent or bulging canal of ICA, presence of pseudoaneurysm, attachment of sphenoid septae to the canal, displacement by the lesion, nonenlarged sella because of small size of lesion or vertically oriented lesions, and vessel wall abnormalities increase the risk of injury. It is very essential to have a preoperative discussion involving the skull base surgeons (neurosurgeons and otorhinolaryngologists), neuroradiologists, and neuroanesthetists regarding the complications expected in the case. In case of ICA bleed, the target should be to achieve a temporary hemostasis. In small tears, cottonoids for pressure and bipolar for cauterization will help stop the bleeding, while in larger tears, giving moderate pressure using crushed muscle and cottonoids to achieve intra-operative hemostasis should be tried. After intraoperative hemostasis, the patient needs to be shifted to angiography suite for endovascular stent placement.

Parathyroidectomy and the Development of New Depression Among Adults With Primary Hyperparathyroidism

Primary hyperparathyroidism (PHPT) is a common endocrine disorder associated with neuropsychiatric symptoms. Although parathyroidectomy has been associated with improvement of preexisting depression among adults with PHPT, the effect of parathyroidectomy on the development of new depression is unknown. To determine the effect of early parathyroidectomy on the incidence of new depression among adults with PHPT compared with nonoperative management. Analyzed data included observational national Veterans Affairs data from adults with a new diagnosis of PHPT from 2000 through 2019 using target trial emulation with cloning, a biostatistical method that uses observational data to emulate a randomized clinical trial. New depression rates were compared between those treated with early parathyroidectomy vs nonoperative management using an extended Cox model with time-varying inverse probability censoring weighting, adjusted for patient demographics, comorbidities, and depression risk factors. Eligible adults with a new biochemical diagnosis of PHPT, excluding those with past depression diagnoses, residing in an assisted living/nursing facility, or with Charlson Comorbidity Index score higher than 4 were included. These data were analyzed January 4, 2023, through June 15, 2023. Early parathyroidectomy (within 1 year of PHPT diagnosis) vs nonoperative management. New depression, including among subgroups according to patient age (65 years or older; younger than 65 years) and baseline serum calcium (11.3 mg/dL or higher; less than 11.3 mg/dL). The study team identified 40 231 adults with PHPT and no history of depression of whom 35896 were male (89%) and the mean (SD) age was 67 (11.3) years. A total of 3294 patients underwent early parathyroidectomy (8.2%). The weighted cumulative incidence of depression was 11% at 5 years and 18% at 10 years among patients who underwent parathyroidectomy, compared with 9% and 18%, respectively, among nonoperative patients. Those treated with early parathyroidectomy experienced no difference in the adjusted rate of new depression compared with nonoperative management (hazard ratio, 1.05; 95% CI, 0.94-1.17). There was also no estimated effect of early parathyroidectomy on new depression in subgroup analyses based on patient age or serum calcium. In this study, there was no difference in the incidence of new depression among adults with PHPT treated with early parathyroidectomy vs nonoperative management, which is relevant to preoperative discussions about the benefits and risks of operative treatment.

Identifying Prevalence and Potential Predictors of Do-Not-Attempt-Resuscitation Orders to Facilitate Preoperative Discussions on Code Status.

Do Not Attempt Resuscitation (DNAR) orders allow patients with life-threatening conditions to decline resuscitation efforts should the need arise. The American Society of Anesthesiologists (ASA) recommends discussions with patients on their code status to clarify and honor their goals of care perioperatively. This project sought to determine the prevalence of DNAR orders and to identify the demographics and potential clinical predictors of DNAR status at the beginning and end of admission, which would help anesthesiologists at our center facilitate these discussions. Factors associated with DNAR status at beginning and at end of hospital stay were determined through univariate logistic regressions. For DNAR status at beginning and end of hospital admission, variables assessed were age at arrival, race, sex, palliative consult, use of palliative care service, length of stay in days, presence of surgery, presence of emergent surgery, care level, and medical service. Approximately 2.4 percent of the sample had an active DNAR order at the beginning of their hospital admission compared to 7.4 percent at the end of hospital admission. Factors significantly associated with DNAR status at the beginning of the hospital stay were consistent with prior literature (age, palliative care consult or service). However, factors significantly associated with DNAR status at the end of hospital stay that were notable included length of stay, undergoing emergent surgery, higher level of care, and being on the oncology service and medical respiratory intensive care unit. This retrospective study allows anesthesiologists at our institution to identify patients who may benefit from a more comprehensive perioperative discussion about code status based on certain clinical characteristics, which may improve quality of care by preventing unwanted resuscitative measures that do not align with a patient's goals of care.

Utility of the mFI-5 as a predictor of post-operative outcomes following gastrectomy for gastric cancer: an ACS-NSQIP analysis

BackgroundGastric cancer is the 5th most common malignancy worldwide. Surgical treatment for the disease can often be highly morbid, especially in elderly patients. The modified 5-item frailty index (mFI-5), a recently developed tool for assessing patient frailty, has been shown to be an effective predictor of post-operative outcomes in various surgical fields. This study aims to assess the utility of the mFI-5 in predicting adverse postoperative outcomes following gastrectomy for gastric cancer.MethodsThe National Surgical Quality Improvement Program (NSQIP) database was queried for patients who underwent partial or total gastrectomy for gastric cancer between 2011 and 2021. The mFI-5 score was calculated based on the presence of hypertension, congestive heart failure, diabetes mellitus, chronic obstructive pulmonary disease, and partially or fully dependent functional status. Patients were stratified into 3 groups according to mFI-5 score (mFI-5 = 0, mFI-5 = 1, mFI-5 ≥ 2). Univariate analysis and multivariate logistic regression were used to evaluate the association between mFI-5 score and post-operative outcomes.Results7438 patients were identified (mFI-5 = 0: 3032, mFI-5 = 1: 2805, mFI-5 ≥ 2: 1601). mFI-5 ≥ 2 was an independent predictor of overall complications (OR 1.43, p < 0.001), serious complications (OR 1.42, p < 0.001), pneumonia (OR 1.43, p = 0.010), MI (OR 2.91, p = 0.005), and readmission within 30 days (OR 1.33, p = 0.008). Patients with higher frailty were more likely to experience unplanned intubation (OR 2.06, p < 0.001; OR 2.47, p < 0.001), failure to wean from the ventilator (OR 1.68, p = 0.003; OR 2.00, p < 0.001), acute renal failure (OR 3.25, p = 0.003; OR 3.27, p = 0.005), 30-day mortality (OR 1.73, p = 0.009; OR 1.94, p = 0.004), and non-home discharge (OR 1.34, p = 0.001; OR 1.74, p < 0.001) relative to non-frail patients.ConclusionHigher frailty, as indicated by an increased mFI-5 score, raises the risk of serious post-operative complications in patients with gastric cancer undergoing gastrectomy. The mFI-5 has the potential to help identify high-risk patients and enhance pre-operative discussions and optimization.Graphical abstract

Frailty is Superior to Age at Predicting Extended Length of Stay and Immediate Postoperative Complications Following Total Wrist Arthrodesis

Abstract Hypothesis The modified five-factor frailty index (mFI-5) is a better predictor than age alone of increased risk of extended length of stay (LOS) and postoperative complications in patients undergoing total wrist arthrodesis (TWA). Methods The National Inpatient Sample database was queried for patients undergoing elective TWA. Patients were identified using the International Classification of Diseases, 10th Revision procedure codes, excluding nonelective cases, hardware removal, and patients with cerebral palsy or seizure disorders. Frailty was assessed by identifying the variables used in the mFI-5 and patients were categorized as nonfrail (mFI-5 = 0), prefrail (mFI-5 = 1), and frail (mFI-5 ≥ 2). Outcomes assessed included LOS and immediate postoperative complications such as nausea and vomiting requiring admission, acute kidney injury, postoperative hypotension, postoperative hypothyroidism, and urinary tract infection. Logistic regression was used to analyze the association between frailty status and both extended LOS and immediate postoperative complications. Results Between 2015 and 2019, 685 patients underwent TWA, with 49.6% not frail, 33.5% prefrail, and 16.7% frail. Prefrail and frail patients were at increased risk of undergoing extended LOS (OR 2.182, p = 0.001; OR 2.312, p = 0.002, respectively). Age over 65 (OR 1.995, p &lt; 0.001) and female sex (OR 1.605, p = 0.029) were also independent risk factors. Frail patients were found to have an increased likelihood of acquiring any postoperative complication (OR 3.865, p &lt; 0.001), while elderly age was not a significant risk factor (OR 1.361, p = 0.298). Using receiver operating characteristic (ROC) curve analysis, the mFI-5 demonstrated superior discriminatory ability compared with age for extended LOS (Area under the curve (AUC) 0.729 vs. 0.542) and postoperative complications (AUC 0.712 vs. 0.673). Conclusion Our study demonstrates that both elderly age and frailty are independent predictors of extended hospitalization following TWA, while frailty but not age, is a significant predictor of immediate postoperative complications. To our knowledge, our study is the first to report an association between frailty status and immediate postoperative complications following TWA. Incorporating a preoperative frailty screening can allow for more open and informed preoperative discussion about surgical risk for elective procedures such as TWA, as well as allow for enhanced postoperative planning.

When does patient function "Plateau" after total joint arthroplasty? A cohort study.

With over 100,000 procedures completed per year, hip and knee arthroplasty are two of the most common surgical procedures performed in Canada. There has been literature indicating that patient reported outcome measures (PROM) will start to plateau between sixand 12months. The purpose of this paper was to analyze the trajectory of PROMs following total hip and knee arthroplasty (THA and TKA), as well as assess the impact of any potential confounders on this trajectory. The central research question was: At what point do PROMS plateau among patients that undergo elective THA and TKA? This study was a retrospective analysis of data from a prospective database. Patients were eligible if they had undergone an elective, primary THA/TKA with Oxford Scores recorded pre-operatively, and at least at two of the following four time points: six weeks, six months, one year, and two years. Mean pre-operative Oxford scores were 18.0 (7.8) for THA, and 20.1 (7.5) for TKA. For both THA and TKA, there were statistically significant interval improvements in Oxford scores from six weeks [THA: 33.8 (7.9)/TKA: 28.7 (7.8)] to six months [THA: 40.2 (7.3)/TKA: 35.9 (8.3)], and from six months to one year [THA: 41.0 (7.3)/TKA: 37.3 (8.4)], but not from one to two years [THA: 40.0 (8.5)/TKA: 36.4 (9.6)]. Patients undergoing either primary THA or TKA can expect clinically meaningful improvements in the first six months after surgery. Beyond this time point, there is a plateau in PROMs. These findings are important for both setting patient expectations in pre-operative discussions, and allowing surgeons to have a realistic understanding of their patients' expected post-operative course.

Analysis of the Perioperative Course of Cardiac Surgery Patients with Coronary Artery Disease and Heart Valve Dysfunction

The aim. To analyze the perioperative course of cardiac surgery patients with coronary artery disease (CAD) and heart valve dysfunction. Materials and methods. Retrospective analysis of 41 consecutive cardiac surgery patients (mean age 61.6 ± 7.8 years) with CAD and heart valve dysfunction who were operated on and discharged from the National Amosov Institute of Cardiovascular Surgery of the National Academy of Medical Sciences of Ukraine. All the patients underwent standard clinical and laboratory examinations, coronary angiography, on-pump cardiosurgical intervention. Results. The patients were divided into three subgroups: patients with post-infarction left ventricular aneurysm (LVA) combined with insufficiency of atrioventricular valves, n = 15 (36.6%); those with ischemic mitral insufficiency (MI), n = 11 (26.8%); and patients with CAD combined with aortic valve disease, n = 15 (36.6%). During echocardiographic study, decreased left ventricular ejection fraction was found in patients with LVA and with ischemic MI: 33 ± 6.4% and 39.4 ± 7.8%, respectively, and in patients with aortic valve disease, left ventricular ejection fraction averaged 48.2 ± 9.9% (p &lt; 0.0001). According to the EuroSCORE II scale, the average risk was 11.8 ± 7.3%. All the patients were discussed by the heart team to choose the optimal method of cardiosurgical correction. In order to reduce the ischemic time, off-pump coronary bypass surgery was performed at the first stage, and the second stage was on-pump correction of valvular dysfunction. The average number of grafts was 2.8 ± 1.4, but the largest number of grafts was in the subgroup of ischemic MI: 4 ± 0.9 (p &lt; 0.005). Mitral valve replacement in patients with LVA was performed through LVA in 12 patients. Acute heart failure, acute renal failure often developed in patients after correction of ischemic MI (p &lt; 0.005). On the 1st day after the operation, there was an increase in average glucose values from 6.6 ± 2.8 to 10.3 ± 2.9 mmol/L (p &lt; 0.0001), a decrease in glomerular filtration rate from 72.1 ± 15.3 to 57 ± 18.8 mL/min/1.73 m2 (p = 0.0001), the above indicators returned to the initial level at discharge (p &lt; 0.0001). Conclusions. Off-pump myocardial revascularization in patients with CAD and dysfunction of the heart valves can significantly reduce the ischemic time. The method of mitral valve replacement through LVA developed in the department allowed to reduce the perfusion time (p = 0.0023) and the duration of the operation (p &lt; 0.005). Preoperative discussion of examination data of patients by the heart team, thorough preparation for cardiac surgery, timely response to changes in laboratory parameters with correction of drug treatment avoid complications.

Optimizing Morbidity in Unplanned Soft Tissue Sarcoma Excisions: Should We Skip the Reconstructive Ladder?

Soft tissue sarcomas (STSs) are rare and diverse primary malignant tumors that comprise approximately 1% of all malignancies. Misdiagnoses and unplanned excisions of STSs are common due to the tumor's rarity, leading to secondary tumor bed excisions (TBEs). Reconstructive outcomes for TBEs remain poorly understood, prompting this study to address the knowledge gap and inform preoperative discussions. This was a retrospective cohort study of patients who underwent STS excisions at a quaternary cancer center. Patients were categorized into mass excision (ME) and TBE groups. Reconstructive approaches were divided into simple (primary closure, complex repair, skin grafts, local flaps) and advanced (pedicled or free flaps). The groups were compared for postoperative outcomes, including complications, recurrence, and death. When simple reconstructive techniques were used, TBEs exhibited higher rates of overall and major complications, whereas MEs had higher rates of overall and minor complications. Intergroup analysis revealed that with simple reconstruction, rates of overall and major complications were higher in TBEs than in MEs, and rates of minor complications were higher in MEs than in TBEs. Regression analyses revealed that simple reconstruction of TBEs had 90% and 180% higher odds of major complications and reoperation compared to simple reconstruction of MEs (P < 0.05). TBEs, despite their smaller size, exhibited a heightened susceptibility to overall and major complications, challenging the notion that simpler techniques suffice in these cases. Our findings encourage the consideration of advanced reconstructive techniques for TBEs that may seem amenable to simple reconstructive techniques.

Associations between surgeons' preoperative expectations of lumbar surgery and patient-reported 2-year outcomes.

Surgeons' preoperative expectations of lumbar surgery may be associated with patient-reported postoperative outcomes. Preoperatively spine surgeons completed a validated Expectations Survey for each patient estimating amount of improvement expected (range 0-100). Preoperative variables were clinical characteristics, spine-specific disability (ODI), and general health (RAND-12). Two years postoperatively patients again completed these measures and global assessments of satisfaction. Surgeons' expectations were compared to preoperative variables and to clinically important pre- to postoperative changes (MCID) in ODI, RAND-12, and pain and to satisfaction using hierarchical models. Mean expectations survey score for 402 patients was a 57 (IQR 44-68) reflecting moderate expectations. Lower scores were associated with preoperative older age, abnormal gait, sensation loss, vacuum phenomena, foraminal stenosis, prior surgery, and current surgery to more vertebrae (all p ≤ .05). Lower scores were associated postoperatively with not attaining MCID for the ODI (p = .02), RAND-12 (p = .01), and leg pain (p = .01). There were no associations between surgeons' scores and satisfaction (p = .06-.27). 55 patients (14%) reported unfavorable global outcomes and were more likely to have had fracture/infection/repeat surgery (OR 3.2, CI 1.6-6.7, p = .002). Surgeons' preoperative expectations were associated with patient-reported postoperative improvement in symptoms and function, but not with satisfaction. These findings are consistent with clinical practice in that surgeons expect some but not complete improvement from surgery and do not anticipate that any particular patient will have markedly unfavorable satisfaction ratings. In addition to preoperative discussions about expectations, patients and surgeons should acknowledge different types of outcomes and address them jointly in postoperative discussions.

Optimizing Safe Opioid Prescribing: A Paradigm Shift in Buprenorphine Management for Orthopaedic Surgery

The worsening opioid epidemic in the United States, exacerbated by the COVID-19 pandemic, necessitates innovative approaches to pain management. Buprenorphine, a long-acting opioid, has gained popularity due to its safety profile and accessibility. Orthopaedic surgeons, encountering an increasing number of patients on buprenorphine, face challenges in perioperative management. This article will update orthopaedic surgeons on new developments in the understanding of buprenorphine as a pain reliever and share evidence-based practice guidelines for buprenorphine management. For patients on buprenorphine for opioid use disorder or chronic pain, the updated recommendation is to continue their home dose of buprenorphine through the perioperative period. The patient’s buprenorphine prescriber should be contacted and notified of any impending surgery. The continuation of buprenorphine should be accompanied by a multimodal approach to analgesia, including a preoperative discussion about expectations of pain and pain control, regional anesthesia, standing acetaminophen, Nonsteroidal anti-inflammatory drugs when possible, gabapentinoids at night for patients under 65 years, cryotherapy, elevation, and early mobilization. Patients can also be prescribed short-acting, immediate-release opioids for breakthrough pain. Transdermal buprenorphine is emerging as an excellent option for the management of acute perioperative pain in both elective and nonelective orthopaedic patients. A single patch can provide a steady dose of pain medication for up to 1 week during the postoperative period. A patch delivery method can help combat patient nonadherence and ultimately provide better overall pain control. In the future, transdermal buprenorphine patches could be applied in virtually all fracture surgery, spinal surgery, total joint arthroplasty, ligament reconstructions with bony drilling, etc. As the stigma surrounding buprenorphine decreases, further opportunities for perioperative use may develop.

The Reconstructive Metaverse - Collaboration in Real-Time Shared Mixed Reality Environments for Microsurgical Reconstruction.

Plastic surgeons routinely use 3D-models in their clinical practice, from 3D-photography and surface imaging to 3D-segmentations from radiological scans. However, these models continue to be viewed on flattened 2D screens that do not enable an intuitive understanding of 3D-relationships and cause challenges regarding collaboration with colleagues. The Metaverse has been proposed as a new age of applications building on modern Mixed Reality headset technology that allows remote collaboration on virtual 3D-models in a shared physical-virtual space in real-time. We demonstrate the first use of the Metaverse in the context of reconstructive surgery, focusing on preoperative planning discussions and trainee education. Using a HoloLens headset with the Microsoft Mesh application, we performed planning sessions for 4 DIEP-flaps in our reconstructive metaverse on virtual patient-models segmented from routine CT angiography. In these sessions, surgeons discuss perforator anatomy and perforator selection strategies whilst comprehensively assessing the respective models. We demonstrate the workflow for a one-on-one interaction between an attending surgeon and a trainee in a video featuring both viewpoints as seen through the headset. We believe the Metaverse will provide novel opportunities to use the 3D-models that are already created in everyday plastic surgery practice in a more collaborative, immersive, accessible, and educational manner.

Establishment of a scoring model for predicting clinical outcomes in patients with unilateral primary aldosteronism after superselective adrenal artery embolization.

Superselective adrenal arterial embolization (SAAE) is a potential alternative treatment for patients with unilateral primary aldosteronism (PA) who refuse unilateral adrenalectomy. Therefore, we aimed to establish a scoring model to differentiate between hypertensive remission after SAAE. This prospective cohort study involved 240 patients who underwent SAAE for unilateral PA. Patients were randomly divided into a model training set and a validation set at a ratio of 7:3. The clinical outcome was a response to hypertension remission, defined as complete, partial, or absent success at 6 months after SAAE. Multivariate logistic regression was performed to identify independent parameters and develop a nomogram to predict clinical outcomes after SAAE. The discrimination, calibration efficacy, and clinical utility of the predictive model were assessed. Five independent predictors were identified: female sex, duration of hypertension, defined daily dose of antihypertensive medication, diabetes, and target organ damage. The above five independent predictors were put into a predictive model that was presented as a nomogram. Using bootstrapping for internal validation, the C-statistic for the predictive model was 0.866 (95% confidence interval [CI]: 0.834 to 0.898). In the validation cohort, the area under the curve (AUC) of the nomogram for predicting hypertension remission after SAAE was 0.809. The present model is the first nomogram-based score that specifically predicts hypertension remission after SAAE in patients with unilateral PA using conventional parameters. This is an effective risk stratification tool that can be used by clinicians for timely and tailored preoperative risk discussions.
