Normothermic Machine Perfusion and Normothermic Regional Perfusion of DCD Kidneys Before Transplantation: A Systematic Review.

To overcome organ shortages, donation after circulatory death (DCD) kidneys are being increasingly used for transplantation. Prior research suggests that DCD kidneys have inferior outcomes compared with kidneys donated after brain death. Normothermic machine perfusion (NMP) and normothermic regional perfusion (NRP) may enhance the preservation of DCD kidneys and improve transplant outcomes. This study aimed to review the evidence surrounding NMP and NRP in DCD kidney transplantation. Two independent reviewers conducted searches for all publications reporting outcomes for NMP and NRP-controlled DCD kidneys, focusing on delayed graft function, primary nonfunction, graft function, graft survival, and graft utilization. Weighted means were calculated for all relevant outcomes and controls. Formal meta-analyses could not be conducted because of significant heterogeneity. Twenty studies were included for review (6 NMP studies and 14 NRP studies). Delayed graft function rates seemed to be lower for NRP kidneys (24.6%) compared with NMP kidneys (54.3%). Both modalities yielded similar outcomes with respect to primary nonfunction (NMP 3.3% and NRP 5.6%), graft function (12-mo creatinine 149.3 μmol/L for NMP and 129.9 μmol/L for NRP), and graft utilization (NMP 83.3% and NRP 89%). Although no direct comparisons exist, our evidence suggests that both modalities have good short- and medium-term graft outcomes and high graft survival rates. Current literature demonstrates that both NMP and NRP are feasible strategies that may increase donor organ utilization while maintaining acceptable transplant outcomes and likely improved outcomes compared with cold-stored DCD kidneys. Further research is needed to directly compare NRP and NMP outcomes.

Juvenile hallux valgus: Comparison of three types of osteotomy and medium-term postoperative results

BackgroundThere is no consensus on the treatment of juvenile hallux valgus (JHV). Numerous surgical techniques have been described, none of which has been proven to be superior and the mid-term results of these methods are not well known. Our objective was to compare the mid-term clinical, radiographic, and functional results of three metatarsal osteotomy techniques. MethodsPatients under 18 years of age operated on for JHV between January 2010 and December 2019 were included in this multicenter retrospective study. Patients were excluded if they had non-idiopathic hallux valgus or if their postoperative follow-up was less than 3 years. The surgical techniques used were metatarsal osteotomies: basimetatarsal, scarf, or distal. During follow-up visits, we collected HMIS-AOFAS (Hallux Metatarsophalangeal Interphalangeal Scale–American Orthopedic Foot and Ankle Society) and Visual Analogue Scale (VAS) scores, acquired radiographs, and recorded complications and recurrences. Secondarily, the study population was stratified according to physis status (open vs. closed). ResultsDuring the study period, 18 patients (26 feet) met the inclusion criteria. The median postoperative follow-up was 6.5 (4.1) years. At the end of follow-up, the median HMIS score was 79.0 (20.0), the mean hallux valgus angle (HVA) improvement was 13.2° (16.8), and the complication and recurrence rates were 31 % and 23 %, respectively. There was no significant difference in the outcome measures between the three techniques or any difference according to physis status at the time of surgery. Discussion and conclusionThe functional and radiographic results of metatarsal osteotomies are good in the medium term, regardless of the osteotomy site. Our results are comparable to those published in the literature. As our sample size was limited, it did not lead to the identification of statistically significant differences.

Medium-term outcomes after magnetic sphincter augmentation vs. fundoplication for reflux disease due to hiatal hernia: a propensity-score matched comparison in 282 patients.

An increasing number of reflux patients opt for magnetic sphincter augmentation (MSA) instead of fundoplication. However, few studies comparethe medium-term efficacy and safety of the procedures. We conducted a retrospective single-center analysis of consecutive MSA and Nissen fundoplication cases between 01/2015 and 06/2020. Patients underwent surgery, including hiatoplasty, for medical treatment-resistant reflux due to hiatal hernia. Surgical revision and proton pump inhibitor (PPI) reuptake rates were the primary outcomes. We also compared adverse event rates. Patients with severe preoperative dysphagia/motility disorders were assigned different treatment pathways and excluded from the analysis. We used propensity-score matching to reduce confounding between treatments. Out of 411 eligible patients, 141 patients who underwent MSA and 141 with fundoplication had similar propensity scores and were analyzed. On average, patients were 55 ± 12years old and overweight (BMI: 28 ± 5). At 3.9years of mean follow-up, MSA was associated with lower surgical revision risk as compared to fundoplication (1.2% vs 3.0% per year, respectively; HR: 0.38; 95% CI 0.15-0.96; p = 0.04), and similar PPI-reuptake risk (2.6% vs 4.2% per year; HR: 0.59; 95% CI 0.30-1.16; p = 0.12). Adverse event rates during primary stay were similar (MSA vs. fundoplication: 1% vs. 3%, p = 0.68). Fewer patients experienced adverse events in the MSA group after discharge (24% vs. 33%, p = 0.11), driven by higher rates of self-limiting dysphagia (1% vs. 9%, p < 0.01) and gas/bloating (10% vs. 18%, p = 0.06) after fundoplication. Differences between MSA and fundoplication in dysphagia requiring diagnostic endoscopy (11% vs. 8%, p = 0.54) or surgical revision (2% vs. 1%, p = 1.0) were non-significant. The device explantation rate was 4% (5/141). MSA reduces the re-operation risk compared to fundoplication and may decrease adverse event rates after discharge. Randomized head-to-head studies between available surgical options are needed.

Preparation and validation of the instrument "QualiAPS digital-Brazil" for assessing digital health care in primary health care: a required tool.

The use of Information and Communication Technologies in the field of health is increasing across the world, demarcating the field of digital health. The goal of this study is to formulate and validate a matrix of indicators, design assessment scripts and indicate data collection techniques for assessing the quality of digital health care in Brazilian Primary Health Care (PHC). This is a validation study divided into three phases: preparation of the instrument, analysis of validity and pilot study. The instrument was prepared based on the PHC assessment model from a literature review; the analysis of validity used the Delphi technique associated with the nominal group and the evidence from the literature reference. In the pilot study, audio-recorded interviews were conducted with strategic primary care actors. The matrix of indicators "QualiAPS Digital-Brazil" introduces a set of 37 indicators, distributed into three distinct components and their respective dimensions. The component "Structure" includes the dimension "Resources"; the component "Processes" includes the dimensions "Technical," "Organizational" and "Relational"; and the component "Results" includes the dimensions "Short-Term Results" and "Medium-Term Results." The general values obtained for CVI and IRR were 0.89 and 1.00; respectively. Therefore, it was possible to design assessment scripts and indicate qualitative data collection techniques for assessing digital health in Brazilian PHC. The instrument presented was validated regarding its relevance, content and theoretical support to evaluate the quality of digital health care, supporting decision-making by managers and health professionals in the search for improving remote primary care provided to the population.

Risk factors associated with radiological and clinical recurrences after laparoscopic repair of large hiatal hernia with TiO2Mesh™ reinforcement.

Laparoscopic repair of large para-esophageal hiatal hernias (LPHH) remains controversial. Several meta-analyses suggest hiatus reinforcement with mesh has better outcomes over cruroplasty in terms of less recurrence. The aim of this study was to evaluate the medium-term results of treating LPHH with a biosynthetic monofilament polypropylene mesh coated with titanium dioxide to enhance biocompatibility (TiO2Mesh™). A retrospective observational study, using data extracted from a prospectively collected database was performed at XXX from December 2014 to June 2023. Included participants were all patients who underwent laparoscopic repair of large (> 5cm) type III hiatal hernia in which a TiO2Mesh™ was used. The results of the study, including clinical and radiological recurrences as well as mesh-related morbidity, were analyzed. Sixty-seven patients were finally analyzed. Laparoscopic approach was attempted in all but conversion was needed in one patient because of bleeding in the lesser curvature. With a median follow-up of 41months (and 10 losses to follow-up), 22% of radiological recurrences and 19.3% of clinical recurrences were described. Regarding complications, one patient presented morbidity associated with the mesh (mesh erosion requiring endoscopic extraction). Recurrent hernia repair was an independent factor of clinical recurrence (OR 4.57 95% CI (1.28-16.31)). LPHH with TiO2Mesh™ is safe and feasible with a satisfactory medium-term recurrence and a low complication rate. Prospective randomized studies are needed to establish the standard repair of LPHH.

Self-expanding intracranial drug-eluting stent system in patients with symptomatic intracranial atherosclerotic stenosis: initial experience and midterm angiographic follow-up.

Symptomatic intracranial atherosclerotic stenosis (ICAS) is a major cause of ischemic stroke worldwide. In patients undergoing endovascular treatment for ICAS, in-stent restenosis (ISR) is associated with ischemic stroke recurrence. Intracranial drug-eluting self-expanding stent systems (COMETIU; Sinomed Neurovita Technology Inc., CHN) are new devices for treating ICAS. This study evaluated the perioperative experience and medium-term outcomes of COMETIU in 16 patients. We prospectively analyzed 16 patients with ICAS (≥ 70% stenosis) who underwent intravascular therapy between September 4, 2022, and February 1, 2023. The primary outcome was the incidence of ISR at 6 months postoperatively. The secondary efficacy outcomes were device and technical success rates. The secondary safety outcomes included stroke or death within 30 days after the procedure and the cumulative annual rate of recurrent ischemic stroke in the target-vessel territory from 31 days to 6 months and 1 year. A total of 16 patients with 16 intracranial atherosclerotic lesions were treated with 16 COMETIUs. All procedures were performed under general anesthesia with 100% device and technical success rates, with no cases of periprocedural stroke or death. The mean radiographic follow-up duration was at least 6 months postoperatively, and all patients presented for radiographic and clinical follow-up. There were no reported ischemic or hemorrhagic strokes. Angiographic follow-up for all patients revealed no cases of ISR. COMETIU is safe and effective for treating ICAS, with minimal risk during the procedure and a low rate of ISR during medium-term follow-up.

Minimally invasive ureteral reimplantation: trends in regions of the Russian Federation and The Republic of Belarus. Multi-center study

Introduction. Until recently, open ureteral reimplantation was considered the gold standard for the surgical treatment of ureterovesical junction (UVJ) pathologies. The introduction of minimally invasive ureteral reimplantation (MIUR) for the treatment of vesicoureteral reflux (VUR) and primary obstructive megaureter (POM) in children started in the 1990s. However, studies describing national trends in the use of minimally invasive and open approaches in the surgical treatment of UVJ pathology in children are limited.Objective. To describe changes in the use of MIUR and open ureteral reimplantation (OUR) between 2007 and 2022 in some regions of the Russian Federation and the Republic of Belarus and compare the results and complication rates of the two surgical approaches. Materials &amp; methods. The study includes 1273 patients (1793 ureters), operated on for UVJ pathology in the period from 2007 to 2022. MIR was performed in 1356 (75.6%) ureters (913 for VUR and 443 for POM). The studied parameters included an annual amount of reimplantation, the age of patients, the frequency of intra- and postoperative complications, as well as the medium-term results of operations.Results. The use of MIUR techniques has increased significantly over time, and in 2022, seventy-five percent of surgeries were performed using MIUR. Analysis of the rate of adoption of MIUR by clinics showed that those that began using it first experienced a significant increase in frequency of use after 4 to 6 years, while those that started later took 2 to 3 years to achieve a significant positive trend. There were 5 (0.4%) intraoperative complications in the MIUR group. All these complications were classified as grade I according to the Satava grading system. There was no significant difference between MIUR and OUR in terms of postoperative complication rates (6.6% vs. 7.6%, p = 0.8). The efficiency of reimplantation was 96.6% in the MIUR group compared to 95.9% in the OUR group for POM and 96.2% in the MIR group compared to 94.6% in the OUR for VUR.Conclusion. In the regions of Russia involved in the study, there has been a trend towards completely replacing open surgery with minimally invasive techniques. Regarding complication rates and efficacy, MIUR is not significantly different from OUR.

[Translated article] Total hip arthroplasty with second generation dual mobility system as a treatment for primary coxarthrosis, medium-term results

IntroductionOsteoarthritis is a disabling pathology characterised by joint pain and stiffness. A prevalence of coxarthrosis of 7.4% is reported in our country. Total hip joint replacement is indicated in advanced stages, a procedure that is not free of complications, the most frequent being prosthetic dislocation, which can be prevented with dual mobility systems. The following study aims to determine the rate of complications and clinical outcomes in dual mobility systems in primary coxarthrosis. Materials and methodsA retrospective study included 120 cases in 114 patients diagnosed with grade III coxarthrosis, mean age was 62.43 years, with a mean follow-up of 4.5 years. Joint replacement was performed by Hardinge approach. All cases were assessed clinically using the Harris Hip Score (HHS) and radiologically to demonstrate mid-term results. ResultsThe preoperative value on the HHS scale had a mean of 56.45, postoperative at one month 74.23; 6 months 85.40; 1 year 94.01 and at 5 years 94.84 points, representing a functional improvement of 17.78 postoperative month; 28.95 at 6 months postoperative; 37.56 at one year postoperative and 38.39 points at 5 years postoperative. A complication rate of 3.44%; 0.86% of complications were associated with the prosthetic components. ConclusionThe dual mobility system should be considered as a therapeutic option in primary hip joint replacement due to excellent functional results and low complication rates. Evidence levelIV. Retrospective observational case series study.

Effectiveness of 3D visualization technologies in planning and performing reconstructive plastic surgeries in patients with elbow contractures caused by ossification

Background. Open reconstructive plastic surgeries are the most radical method of treating patients with elbow contractures caused by ossification. However, these surgeries pose a serious problem due to the large number of unsatisfactory results. The aim of the study is a comparative assessment of the effectiveness between standard techniques and 3D visualization technologies in the surgical treatment of patients with elbow contractures caused by ossification. Methods. Using random number generation, all patients (n = 71) were randomized into two groups. The first group included 34 patients with elbow contractures caused by ossification that underwent surgical intervention using 3D technologies to assess the ossification process. The second group enrolled 37 patients with a similar nosology that underwent standard examination and surgical treatment. The results were evaluated intraoperatively and 180 days after the surgery. The data were obtained from primary medical records and further survey. Results. The application of new planning technology and tactics for onstructive plastic surgeries made it possible to reduce the surgery time by 1.2 times (p0.05), reduce blood loss by 1.3 times (p0.05) and increase the relative number of patients with sufficient movement volume by 10.6% (p0.05). The assessment of various performance parameters (range of motion, pain syndrome, quality of life etc.) showed that after 6 months in the main group, the relative number of patients with problems related to the operated joint was significantly lower than in the control group: 20.5% vs 84.7% (p0.05). Conclusions. The data obtained indicate that the use of the new technique for planning and performing reconstructive plastic surgery in patients with elbow contractures caused by ossification contributes to a less invasive intervention and achievement of better intraoperative and medium-term treatment results.

Cardiopulmonary Complications after Pulmonary Embolism in COVID-19.

Although pulmonary embolism (PE) is a frequent complication in COVID-19, its consequences remain unknown. We performed pulmonary function tests, echocardiography and computed tomography pulmonary angiography and identified blood biomarkers in a cohort of consecutive hospitalized COVID-19 patients with pneumonia to describe and compare medium-term outcomes according to the presence of PE, as well as to explore their potential predictors. A total of 141 patients (56 with PE) were followed up during a median of 6 months. Post-COVID-19 radiological lung abnormalities (PCRLA) and impaired diffusing capacity for carbon monoxide (DLCOc) were found in 55.2% and 67.6% cases, respectively. A total of 7.3% had PE, and 6.7% presented an intermediate-high probability of pulmonary hypertension. No significant difference was found between PE and non-PE patients. Univariate analysis showed that age > 65, some clinical severity factors, surfactant protein-D, baseline C-reactive protein, and both peak red cell distribution width and Interleukin (IL)-10 were associated with DLCOc < 80%. A score for PCRLA prediction including age > 65, minimum lymphocyte count, and IL-1β concentration on admission was constructed with excellent overall performance. In conclusion, reduced DLCOc and PCRLA were common in COVID-19 patients after hospital discharge, but PE did not increase the risk. A PCRLA predictive score was developed, which needs further validation.

Retrospective analysis of medium-term outcomes following anterior lumbar interbody fusion surgery performed in a tertiary spinal surgical centre.

Anterior lumbar interbody fusion (ALIF) can treat spondylolisthesis, degenerative disc disease and pseudoarthrosis. This approach facilitates complete discectomy, disc space distraction, indirect decompression of neural foramina and placement of large interbody devices. Several intra- and postoperative complications can be attributed to the anterior approach: vascular/visceral injury, hypogastric plexus injury and urogenital consequences. Spine-specific complications include implant migration, graft failure, pseudoarthrosis and persistent symptomology. This retrospective study reviewed patient demographics, medium-term outcomes and complication rates following ALIF surgery performed over a 5-year period. A total of 110 consecutive patients had undergone ALIF surgery at a single tertiary spinal centre. The database was reviewed with a primary outcome of identifying postoperative 90-day complications and whether a revision anterior operation was required after primary ALIF. No patients required revision anterior operation after their primary ALIF surgery by final follow-up. Out of 110 patients, 11 (10%) recorded a complication attributed to the anterior stage of their operation within 90 days. Our 90-day complication rate of 10% lies within the 2.6% acute complication and 40% overall complications rates described in previous literature. The risk of vascular/visceral injury is significant (3%) and we recommend that ALIF be performed as a dual surgeon procedure with a vascular-trained access surgeon accompanying the spinal surgeon. ALIF is a valid revision surgical option for failed posterior approaches leading to complications such as pseudoarthrosis. In our sample, 89% of patients were managed with posterior fixation to augment the anterior fusion as, biomechanically, this is a proven construct.

Surgical management of combined osteoarthritis knee and proximal tibial stress fracture via long tibial stem total knee arthroplasty: assessment of medium-term results

Background The combined osteoarthritis knee and proximal tibial stress fracture is an uncommon condition that increases the complexity of the management for both. No common consensus among surgeons regarding management guidelines. We assessed the medium-term results (minimum 5 years) of using long tibial stem total knee arthroplasty (TKA) to restore limb alignment, achieve fracture union, and resurface the arthritic joint in a single procedure. Methods Total of 23 patients with combined osteoarthritis knee and proximal tibial stress fracture were enrolled in this study. Of those 23 patients, 18 were females and five were males. All patients were managed surgically by TKA (PCL sacrificing) with a long tibial stem (straight or with offset). Assessments of union and tibiofemoral alignment were carried out using radiographs. Clinically, patients were evaluated by assessment of knee range of motion, knee society score (KSS), and knee injury and OA outcome score. Results The average follow-up period was 6.5 ± 2.3 years (range from 5 to 9 years) all fractures united in 3–8 months (average 3.2 months), and mean range of motion improved from 89°±8° to 119°±6°, mean knee society score improved from 32 ± 8 to 87 ± 5, mean knee injury osteoarthritis outcome score improved from 27 ± 6 preoperatively to 79 ± 5 after a minimum of 5 years follow-up. no complications (instability, infection, or patella mal-tracking) were reported, although 1 case had a femoral intraoperative condyle fracture which was fixed by screws with no effect on the outcome. Conclusion The use of a long tibial stem TKA is an effective and reproducible single surgical procedure in the management of combined osteoarthritis knee and proximal tibial stress fracture. Satisfactory clinical scores and radiological outcomes were achieved and proper limb alignment was restored obviating the need for further fixation or grafting.

Ventral Onlay Buccal Mucosa Graft Urethroplasty for Female Urethral Stricture: Medium-term Results in a Single Surgeon Experience

ObjectiveTo describe our own approach using buccal mucosal grafting and to assess the outcome of this approach. Materials and MethodsA total of 42 patients underwent ventral onlay BMG by a single surgeon between 2017 and 2022. A longitudinal incision along the length of the urethra was made through the anterior vaginal wall and the peri-urethral fascia was incised to create two flaps. This ventral urethrotomy ran from the meatus into the proximal health urethra above the level of the stricture.A buccal mucosal graft was harvested and sutured to the margins of the urethral mucosa itself and the flaps of peri-urethral fascia. The vaginal wall was then closed. ResultsThe mean age of the patients was 53.6 ± 12.8 years. There were no perioperative or postoperative complications. At a mean follow-up of 38.1 months, 41 patients (98%) were stricture-free. Peak flow rate improved from a mean of 7.7 ± 3.2 ml/s preoperatively to 25.9 ± 5.9 ml/s postoperatively. No patient developed incontinence. One patient developed a recurrent urethral stricture which was treated by redo urethroplasty. ConclusionsThe surgical technique applied has proved efficiency. The ventral BMG preserves the urethral sphincter and so avoids postoperative incontinence. The use of peri-urethral fascia represents a good vascular and mechanical support for the graft.

Surgical Management of Massive Irreparable Cuff Tears/Management of Rotator Cuff Disease: Interpositional Graft for Irreparable Posterosuperior Rotator Cuff Tears.

Increasingly, massive irreparable rotator cuff tears present a treatment challenge due to their high re-tear rates. The reparability of such tears depends on factors like tear size, the number of involved tendons, tendon retraction extent, muscular atrophy, fatty infiltration, and the presence or absence of arthritis. There are non-surgical and several surgical treatment options described each with their specific indications, contraindications, pros, and cons. Bridging reconstruction restores the superior rotator cuff tissue and arrests humeral head superior migration. The purpose of his review is to explore the existing literature on interpositional graft mechanics, indications, surgical technique, and clinical outcomes. It aims to understand how these parameters can facilitate the incorporation of bridging reconstruction using interpositional grafts into a surgeon's practice for managing massive irreparable rotator cuff tears. Interpositional grafts for irreparable massive rotator cuff tears can either be auto-, allo-, xenografts, or synthetic material and are best suited for patients who are relatively younger, no glenohumeral arthritis, and minimal to no fatty infiltration and muscle atrophy. Short to medium term outcome studies available report good functional, clinical, and radiological improvements with bridging reconstruction utilizing acellular dermal matrix allograft. Interpositional grafts for management of irreparable posterosuperior cuff tears provides improved clinical and radiological outcomes with minimal complications and thus a viable and valuable surgical technique for a shoulder surgeon's armamentarium.

Evaluating bacterial contamination and surgical site infection risks in intracorporeal anastomosis: Role of bowel preparation.

We recently read the study by Kayano et al on intracorporeal anastomosis (IA) for colon cancer, which assessed bacterial contamination and medium-term oncological outcomes and affirmed that IA is analogous to extracorporeal anastomosis in reducing intraperitoneal bacterial risk and achieving similar oncological results. Our commentary addresses gaps, particularly concerning bowel preparation and surgical site infections (SSIs), and highlights the need for comprehensive details on the bowel preparation methods that are currently employed, including mechanical bowel preparation, oral antibiotics (OA), their combination, and specific OA types. We emphasize the necessity for further analyses that investigate these methods and their correlation with SSI rates, to enhance clinical protocol guidance and optimize surgical outcomes. Such meticulous analyses are essential for refining strategies to effectively mitigate SSI risk in colorectal surgeries.

Medium-Term Patient-Reported Outcomes after Surgical Management of Perilunate Injury: A Multiinstitutional Experience

Abstract Background There is a lack of consensus on the optimal treatment of perilunate injuries (PLIs). Open reduction with internal fixation with scapholunate (SL) ligament repair is recommended; however, procedures such as lunotriquetral (LT) ligament repair, carpal tunnel release (CTR), proximal row carpectomy, denervation, and arthrodesis may also be used. Purpose The purpose of this study was to assess patient-reported outcomes (PROs) after surgical management of PLIs. Methods A retrospective review of surgically treated PLIs at two institutions in a major metropolitan city from 2014 to 2020 was conducted. Demographics, radiographic data, and details of surgical management were reviewed. PROs were prospectively collected and analyzed. Results Eighty-seven patients with surgically managed PLIs were identified. The average time to surgery was 4 ± 7days. Twenty-six percent of patients presented with acute median neuropathy. Thirty-seven patients provided PROs for analysis. Patient-Rated Wrist Evaluation scores were 22 ± 12.9, 14.4 ± 11.3, and 37 ± 22 for pain, function, and total scores, respectively. Satisfaction was 7 ± 3 Sixteen percent of patients were unable to maintain employment due to their injury. The interval to return to work was 6.3 ± 7.7 months. Conclusion PLIs cause significant morbidity and affect patients' ability to return to work. While open reduction with SL repair is routinely performed to treat PLIs, additional procedures may be considered. Undergoing concurrent CTR in the absence of neurological symptoms showed no differences in outcomes. Level of Evidence Level III, retrospective cohort study.

Endoscopic excision of breast fibroadenoma through inframammary fold: Feasibility, safety and medium-term outcomes.

Endoscopic-assisted surgery for breast tumors has the advantage of inconspicuous scars, less breast volume loss, and nipple areolar distortion. A novel endoscopic-assisted technique through inframammary fold for excision of fibroadenomas is presented. Endoscopic-assisted excision of fibroadenoma(s) through inframammary fold was performed in four patients after informed written consent via three ports (12, 5, and 5 mm). Breast Cancer Treatment Outcome Score-12 (BCTOS-12) was used to evaluate patient satisfaction after surgery. No intraoperative and wound complication was noted. On median follow-up of 26.5 months, patients reported satisfactory responses to aesthetic and functional outcomes. No scar related complications were noted. Endoscopic-assisted excision of fibroadenoma through inframammary fold can be a safe and feasible option with good aesthetic outcomes.

Prognostic factors for recurrent instability in recreational athletes following arthroscopic Bankart repair: a retrospective study with an average 4.1-year follow-up

BackgroundExtensive research has been conducted to investigate the short-term and long-term outcomes of arthroscopic Bankart repair, yielding varying results across different populations. However, there remains a dearth of studies specifically focused on evaluating outcomes in recreational athletes.MethodsA retrospective case series study was conducted on recreational athletes who underwent isolated arthroscopic Bankart repair between 2013 and 2021. The primary outcome assessed was recurrent instability, defined as dislocation or subluxation. Secondary outcomes included patient satisfaction, rates of returning to the same sports (RTS) and RTS at preinjury level, and patient-reported outcomes. Evaluation of the Rowe score, Constant score, American Shoulder and Elbow Surgeons score, and VAS pain score were performed. Prognostic factors for recurrent instability, including demographic and clinical characteristics, as well as postoperative magnetic resonance imaging (MRI) appearance of the labrum were analyzed.ResultsA total of 191 patients met the selection criteria, with 150 (78.5%) available for the final follow-up. Recurrent instability occurred in 10.7% of patients, with a mean follow-up duration of 4.1 years. Younger age at surgery and more critical glenoid bone loss were significantly associated with recurrent instability (p = .038 and p = .011, respectively). The satisfaction rate regarding surgery was 90.0%. Rates of return to the same sports (RTS) and RTS at preinjury level were 82.0% and 49.3%, respectively. Clinical outcomes measured at the final follow-up were as follows: Rowe score − 92.8; Constant score − 98.0; ASES score − 98.3; VAS pain score − 0.2. Patients with recurrent instability had significantly inferior outcomes in terms of satisfaction rate, RTS at preinjury level rate, Rowe score, and Constant score (p = .000, p = .039, p = .000, and p = .015, respectively). A total of thirty-seven patients underwent MRI examination six months after surgery in our institution. The T2-weighted anterior labrum morphology was found to be poorer in patients with recurrent instability. No significant difference was observed between patients with or without recurrent instability in terms of anterior Slope, anterior labral glenoid height index (LGHI), inferior Slope, inferior LGHI, and T2-weighted inferior labrum morphology.ConclusionArthroscopic Bankart repair can yield satisfactory medium-term outcomes for recreational athletes. Younger age at surgery, more critical glenoid bone loss, and poorer T2-weighted anterior labrum morphology assessed six months postoperatively were significantly associated with recurrent instability.

Learning curve in tibial and pedal bypass with autologous vein graft.

The 2019 Global Vascular Guidelines recommended open bypass for patients at average risk with greater limb severity and anatomical complexity. However, the outcomes of tibial and pedal bypass (TPB) are inferior to those of above-the-knee surgical revascularization. This may be due to the technical difficulty and need for development of skills to perform TPB. However, there is a limited knowledge on the learning curve in TPB. Thus, the aim of the study is to assess this learning curve in a single-center retrospective analysis. Cases treated with TPB with an autologous vein conduit in patients with chronic limb-threatening ischemia (CLTI) at a Japanese single center from 2009 to 2022 were analyzed retrospectively. The primary endpoint was the learning curve for TPB. The study included 449 TPB procedures conducted by a single main surgeon in patients with CLTI (median age, 75 years; 309 males; diabetes mellitus, 73%; end stage renal failure with hemodialysis, 44%). The operative time decreased significantly as the number of cases accumulated (p < .001). Using the cumulative sum (CUSUM) operative time, the learning curve was estimated to be phase 1 (initial learning curve) for 134 cases (1-134); phase 2 (competent period) for 179 cases (135-313); and phase 3 (mastery and challenging period) for 136 cases (314-449). The mean follow-up period was 34 ± 31months. The 1- and 3-year limb salvage rates of 97% and 96% in phase 3 were significantly higher than those in phases 1 and 2 (p < .001, p = .029). Major adverse limb events (MALE) occurred in 117 (26%) patients, and the 1- and 3-year MALE rates of 10% and 17% in phase 3 were significantly lower than those in phases 1 and 2 (p < .001, p = .009). In the study, vascular surgeon required a learning curve of 134 TPB cases to Overcoming the learning curve for bypass was associated with improvement of medium-term outcomes for limb salvage and freedom from MALE.

Utilizing Single-Branched Stent in Combination With Fenestration or Chimney for Endovascular Repair of Aortic Arch Lesions With Aberrant Subclavian Artery.

The study was to figure out the feasibility, efficacy, and safety of a single-branched stent graft, namely Castor, in combination with fenestration or chimney in the context of aortic arch lesions presenting with aberrant subclavian artery (ASA) and/or Kommerell's diverticulum (KD). All consecutive patients with aortic arch lesions and ASA and/or KD receiving Castor from June 2018 to June 2023 were investigated. Incorporating 18 patients, the study encompassed 11 cases with KD, 3 cases with dysphagia; 2 cases of right-sided aortic arch with left-sided aberrant left subclavian artery (ALSA), and 16 cases of left-sided aortic arch with right-sided aberrant right subclavian artery (ARSA). The mean operation time was 132±23 minutes. The mean measured proximal aortic diameter was 30.9±1.6 mm, and proximal diameter of Castor stent was 34 (32, 34.5) mm, with oversize of 9.1±1.6%; the mean measured branch diameter was 8.8±0.97 mm, and branch diameter of Castor stent was 10 (8, 10) mm, with oversize of 0.86±0.57 mm. Technical success rate was 100%, and no in-hospital mortality, no stroke, and no endoleak were identified. One (5.6%) case with spinal cord ischemia and one (5.6%) case with poor healing of operative site were identified. During the follow-up period, no aortic-related death or secondary intervention was recorded. The maximal aortic diameter was significantly reduced at the sixth postoperative month (padj=0.031); KD diameter was significantly reduced at the third (padj=0.001) and sixth (padj<0.001) postoperative month. Totally endovascular repair of aortic arch lesions with ASA and KD via Castor stent in combination with fenestration or chimney is feasible, effective, and safe, which can achieve an encouraging medium-term outcome and provide excellent remodeling at the lesions. Single branched stent in combination with fenestration or chimney achieved a sufficient proximal landing zone and provided an encouraging medium-term outcome in this retrospective review of 18 patients receiving endovascular treatment of pathological aortic arch with aberrant subclavian artery and/or Kommerell's diverticulum. The authors suggest this time-saving and efficient technique to establish systematic experience for the treatment in this kind of patients.
