Right Thoracoscopic Excision of an Esophageal Bronchogenic Cyst.

Bronchogenic cysts, first described in 1859, are rare congenital cystic malformations of the respiratory tract, with an incidence of one per 42,000-68,000 hospital admissions in one hospital series. They comprise 10-15% of mediastinal tumors and between 50% and 60% of mediastinal cystic lesions. Its clinical diagnosis is often challenging due to the absence of distinct imaging features. This case report focuses on the case of a 51-year-old female who initially received a misdiagnosis of esophageal leiomyoma. Subsequently, during exploration in the operating theater, right thoracoscopy revealed the presence of an esophageal bronchogenic cyst.

First impressions of Telesurgery robotic-assisted radical prostatectomy using the Edge medical robotic platform.

PURPOSE: We reported, as a referral center in prostate cancer, our perspectives and experience performing Telesurgery using robotic surgery and 5G network. MATERIAL AND METHODS: We described and illustrated the Telesurgery applications and outcomes to treat a patient with prostate cancer located 1300 kilometers away from the surgeon (Beijing-Harbin) in China. We used the Edge Medical Robot (MP1000) in November 2023 in a 71-year-old patient with Gleason 6 (ISUP 1) in 8 cores from 13, PSA of 14 ng/dL, and clinical stage cT2a. MRI described a PIRADS 5 nodule on the left peripheral zone at the base, and 20gr prostate. We described details about the connection between centers, perioperative outcomes, and our perspectives as a referral center in prostate cancer. RESULTS: We had no delays, or problems with network connection between the centers. The procedure was performed in 60 minutes, with no intra- or postoperative complications. Estimated blood loss was 100 mL. The patient was ambulating soon after anesthesia recovery. Final pathology described a Gleason 6 (ISUP 1) involving the left base and left seminal vesicle, negative surgical margins, and no lymph node involvement (pT3bN0). The patient was continent soon after catheter removal (7 days). CONCLUSION: As technological progress introduced novel robotic platforms and high-speed networks, the concept of Telesurgery became a tangible reality while 5G technology solved latency and transmission concerns. However, with these advancements, ethical considerations and regulatory frameworks should underline the importance of transparency and patient safety with responsible innovation in the field.

The 2012 Briganti nomogram not only predicts lymph node involvement but also disease progression in surgically treated intermediate-risk prostate cancer patients with PSA <10 ng/mL, ISUP grade group 3, and clinical stage up to cT2b

ABSTRACT Purpose We assessed the prognostic impact of the 2012 Briganti nomogram on prostate cancer (PCa) progression in intermediate-risk (IR) patients presenting with PSA <10ng/mL, ISUP grade group 3, and clinical stage up to cT2b treated with robot assisted radical prostatectomy eventually associated with extended pelvic lymph node dissection. Materials and Methods From January 2013 to December 2021, data of surgically treated IR PCa patients were retrospectively evaluated. Only patients presenting with the above-mentioned features were considered. The 2012 Briganti nomogram was assessed either as a continuous and a categorical variable (up to the median, which was detected as 6%, vs. above the median). The association with PCa progression, defined as biochemical recurrence, and/or metastatic progression, was evaluated by Cox proportional hazard regression models. Results Overall, 147 patients were included. Compared to subjects with a nomogram score up to 6%, those presenting with a score above 6% were more likely to be younger, had larger/palpable tumors, presented with higher PSA, underwent tumor upgrading, harbored non-organ confined disease, and had positive surgical margins at final pathology. PCa progression, which occurred in 32 (21.7%) cases, was independently predicted by the 2012 Briganti nomogram both considered as a continuous (Hazard Ratio [HR]:1.04, 95% Confidence Interval [CI]:1.01-1.08;p=0.021), and a categorical variable (HR:2.32; 95%CI:1.11-4.87;p=0.026), even after adjustment for tumor upgrading. Conclusions In IR PCa patients with PSA <10ng/mL, ISUP grade group 3, and clinical stage up to cT2b, the 2012 Briganti nomogram independently predicts PCa progression. In this challenging subset of patients, this tool can identify prognostic subgroups, independently by upgrading issues.

The surgical technique and protocol for dynamic sentinel node biopsy for penile cancer at a Southeast Asian regional hospital.

Lymph node status is a key prognostic factor in penile cancer. The European Association of Urology (EAU) recommends intermediate-risk (pT1a, Grade 2) or high-risk (pT1b or greater) penile cancer patients with clinically non-palpable inguinal lymph node (cN0) to undergo either an invasive bilateral modified inguinal lymph node dissection (ILND) or dynamic sentinel node biopsy (DSNB). DSNB has been reported to have acceptable false negative rates, and lower rates of long-term morbidity compared to ILND. We developed a protocol for DSNB at a regional hospital in Singapore that was adopted from St James's University Hospital, Leeds Teaching Hospitals Trust. Four patients with cN0 penile cancer underwent DSNB between November 2021 and October 2022 according to this protocol. Our surgical technique and protocol are described. The patients' oncological characteristics and their outcomes were evaluated. In this small case series, there was no complication attributable to the performance of DSNB, and there was no groin that was documented to be false negative over a median follow up of 15.5 months (range, 12 to 22 months). Using our protocol, 5 of 8 groins (62.5%) were able to avoid ILND in the cN0 setting. We recommend the adoption of DSNB for the surgical staging of inguinal lymph nodes for patients with intermediate to high-risk penile cancer and non-palpable inguinal nodes due to its significantly lower risks of long-term morbidity compared to ILND. Appropriate specialist training and a multi-disciplinary team is vital to ensure the success of the procedure.

Multiparametric-magnetic resonance imaging (mp-MRI) of the prostate and Urolift: Identifying artefact size, location and clinical implications.

Objectives: We sought to define the degree of artefact caused by prostatic urethral lift (PUL) on multiparametric-magnetic resonance imaging (mp-MRI) to determine the location, size of artefact and if the device could potentially obscure a diagnosis of prostate cancer. Methods: Ten patients were prospectively enrolled to undergo PUL for treatment of benign prostatic hyperplasia and follow-up imaging. A standard mp-MRI protocol using a 3.0 Tesla scanner was performed prior to and following Urolift insertion. Pre- and post-PUL images were compared to measure maximum artefact diameter around each implant in each MRI parameter. A transverse relaxation time weighted (T2) artefact reduction protocol was also evaluated. The location of each artefact was then compared to a separate database of 225 consecutive patients who underwent magnetic resonance guided prostate biopsies. Results: Artefact occurred around the stainless steel urethral implant component only. Mean T2 artefact maximum diameter was 7.7 mm (sd = 1.71 mm), with an artefact reduction protocol reducing this to 5.4 mm (sd = 1.43). Mean dynamic-contrast-enhancement artefact was 10 mm (sd = 2.5 mm), and mean diffusion-weighted-imaging artefact was 28.2 mm (sd = 7.8 mm). All artefacts were confined to the posterior transition zone only. In the 225 consecutive patients who had undergone magnetic resonance guided prostate biopsies, there were 55 positive biopsies with prostate cancer, with 13 cases found in the transition zones and no cancer identified solely in the posterior transitional zone. Conclusions: The stainless steel urethral component of the PUL does cause artefact, which is confined to the posterior transition zone only. PUL artefact occurs in an area of the prostate that has a very low incidence of a single focus of prostate cancer. If there is concern for prostate cancer in the posterior TZ (e.g. if every other area is clear with a high PSA), this area can undergo targeted biopsy.

The Lung Cancer Surgical Study Group of the Japan Clinical Oncology Group: outstanding contribution and entering a new phase.

The Lung Cancer Surgical Study Group (LCSSG) of the Japan Clinical Oncology Group (JCOG) was organized in 1986 and initially included 26 collaborative institutions, which has increased to 52 institutions currently. JCOG-LCSSG includes thoracic surgeons, medical oncologists, pathologists, and radiotherapists. In the early period, the JCOG-LCSSG mainly focused on combined modality therapies for lung cancer. Since the 2000s, the JCOG-LCSSG has investigated adequate modes of surgical resection for small-sized and peripheral non-small cell lung cancer and based on the radiological findings of whole tumor size and ground-glass opacity. Trials, such as JCOG0802, JCOG0804, and JCOG1211, have shown the appropriateness of sublobar resection, which has significantly influenced routine clinical practice. With the introduction of targeted therapy and immunotherapy, treatment strategies for lung cancer have changed significantly. Additionally, with the increasing aging population and medical costs, tailored medicine is strongly recommended to address medical issues. To ensure comprehensive treatment, strategies, including surgical and nonsurgical approaches, should be developed. Currently, the JCOG-LCSSG has conducted numerous clinical trials to adjust the diversity of lung cancer treatment strategies. This review highlights recent advancements in the surgical field, current status, and future direction of the JCOG-LCSSG.

Learning curve analysis for hand-assisted laparoscopic living donor nephrectomy: an analysis of 96 consecutive cases performed by a trained gastrointestinal surgeon.

Purpose: This study aims to analyze the learning curve of hand-assisted laparoscopic living donor nephrectomy (HLDN) conducted by a trained gastrointestinal surgeon. Methods: A retrospective analysis was performed on the perioperative clinical data of 96 consecutive patients who underwent HLDN from May 2013 to March 2023. The learning curve was evaluated using the cumulative sum (CUSUM) test based on operation time and risk-adjusted CUSUM for postoperative complications. Patients were divided into three groups (novice, development, and competency phases) based on changes in operation time. Patient demographics and perioperative outcomes were compared between each group. Results: Among the patients, 35 were male, with a mean age of 48.9 ± 11.3 years and a mean body mass index (BMI) of 24.5 ± 3.2 kg/m2. The novice phase (phase 1) included the first 30 cases, with the development phase (phase 2) up to the 65th case. Operation times were significantly different across phases, averaging 263.2 ± 33.4, 211.1 ± 34.4, and 161.1 ± 31.3 minutes for phases 1, 2, and 3, respectively (P < 0.001). Blood loss decreased gradually across phases (phase 1, 264.7 ± 144.4 mL; phase 2, 239.7 ± 166.3 mL; phase 3, 198.8 ± 103.5 mL), though not statistically significant. BMI impacted operation time only in phase 1. Overall postoperative complications occurred in 13 cases (Clavien-Dindo grade I, 4 cases; grade II, 9 cases), with no significant differences across phases. Conclusion: HLDN can be safely performed by a trained gastrointestinal surgeon, with approximately 30 cases needed to achieve proficiency.

Conservative versus Invasive Approaches in Temporomandibular Disc Displacement: A Systematic Review of Randomized Controlled Clinical Trials.

BACKGROUND: Temporomandibular disorders (TMDs) frequently cause orofacial pain and dysfunction, with treatment options spanning from conservative therapies to invasive surgical procedures. The aim of this systematic review was to analyze and compare the efficacy and safety profiles of conservative, minimally invasive interventions and surgical procedures in patients diagnosed with TMDs and disc displacement. METHODS: Following PRISMA recommendations, PubMed, Scopus, and Web of Science databases were searched for randomized clinical trials (RCT). Data were synthesized in a table and evaluated through the Cochrane risk of bias 2 (RoB 2) tool. RESULTS: Thirty-eight RCTs, most with moderate RoB, were selected. Conservative approaches, including physical therapy and occlusal devices, led to an improvement in symptoms and function. Pharmacological treatments demonstrated effectiveness in reducing pain and improving function; however, they can have undesirable side effects. Minimally invasive and invasive treatments also demonstrated efficacy, although most trials did not show their superiority to conservative treatments. CONCLUSION: The primary approach to TMDs should be a conservative, multimodal treatment plan tailored to patient complaints and characteristics. Treatment goals should focus on symptom control and functional recovery. Surgical treatment should be reserved for cases with a precise diagnosis and a clear etiology.

Standardization of robot-assisted radical nephroureterectomy via intraperitoneal approach: insights from a high-volume Japanese Center.

We present the trial-and-error process of standardizing robot-assisted radical nephroureterectomy (RANU) at a high-volume center in Japan. Our urology team performed 53 RANU cases using the Da Vinci Xi system, undergoing five major evolutionary stages. We performed RANU via transperitoneal approach in all cases and lymph-node dissection in selected cases. During the evolution, we adopted a lithotomy position and significantly modified port placement to facilitate lower ureter management. However, we ultimately arrived at a method that minimizes port and patient repositioning during lower ureter processing. By strategically placing ProGrasp™ forceps in the most caudal port, we effectively retracted the bladder and grasped the opened bladder wall during lower ureter manipulation. This approach also allowed us to perform pelvic, para-aortic, and renal portal lymph-node dissection without major changes in patient positioning or port placement. Nevertheless, we acknowledge that some variations in positioning and techniques may be necessary depending on specific case requirements.

Robotics in interventional endoscopy-evolution and the way forward.

The integration of robotics into gastrointestinal (GI) endoscopy represents a transformative advancement and bears the potential to bridge the gap between traditional limitations by offering unprecedented precision and control in diagnostic and therapeutic procedures. This review explores the historical progression, current applications and future potential of robotic platforms in GI endoscopy. Originally designed for surgical applications, robotic systems have expanded their reach into endoscopy, potentially enhancing procedural accuracy and reducing ergonomic strain on practitioners. Natural Orifice Transluminal Endoscopic Surgery (NOTES) emerged as a promising technique, leveraging natural orifices to perform minimally invasive surgeries. Despite its initial potential, several factors, including limitations of the available instrumentations and lack of reliable closure techniques, hindered its widespread adoption and progress. Conventional endoscopic tools often fall short in terms of triangulation, traction and degrees of freedom, necessitating the adoption of robotic interventions. Over recent decades, robotic endoscopy has significantly evolved, focusing on both diagnostic and complex therapeutic procedures such as endoscopic sub-mucosal dissection (ESD) and endoscopic full-thickness resection (EFTR). Various robotic platforms demonstrate enhanced safety and efficiency in GI procedures. As the field progresses, the emphasis on clinical validation, advanced training and the exploration of new applications remains crucial. Continuous innovation in robotic technology and endoscopic techniques promises to overcome existing limitations, further revolutionizing the management of GI diseases and improving patient outcomes.

Global scientific production on gasless laparoscopy: a bibliometric analysis.

Objectives: To characterize the bibliometric characteristics of the global scientific production of original research on gasless laparoscopy in the Web of Science Core Collection (WoSCC) platform. Materials and methods: A bibliometric study of original articles published up to the year 2023 was carried out. Articles were included following the selection criteria in the Rayyan web application, indexed in the Scopus database. The bibliometric analysis was performed using the Bibliometrix program in the R programming language and VOSviewer. The bibliometric characteristics evaluated were articles, journals, citations, publications, ten most mentioned articles, journals with the highest number of publications, authors and institutional affiliations; and cooccurrence of terms. Results: A total of 223 publications were included, with the highest number of articles being published in the years 1999 and 2014. The publication with the most citations was found to be a randomized trial by Galizia G in 2001 with 132 citations. We identified 846 authors involved in the production of articles on gasless laparoscopy, with Nakamura H being the most productive author with 15 articles between the years 2007 and 2020, followed by Takeda A and Imoto S, all three affiliated with "Gifu Prefectural Tajimi Hospital". The country with the highest production was Japan with 64 publications, followed by China and Italy with 46 and 18 publications, respectively. In the top 10 journals with the highest number of publications, "Surgical Endoscopy-Ultrasound and Interventional Techniques" is in first place with 20 articles published on gasless laparoscopy; in addition, most of these are located in Q1 and Q2. Regarding the terms or keywords, it was found that the initial studies had terms related to the disadvantages of pneumoperitoneum and later focused on more specific topics of the application of gasless laparoscopy. Conclusions: Production on gasless laparoscopy has stagnated, with the topics of interest currently being its application in new, less invasive techniques. The most productive countries are found in the Asian and European continents, with little information collected in Latin America. This fact makes it necessary to increase the production of studies to promote this technique and its possible advantages.

Minimally invasive pelvic exenteration for primary or recurrent locally advanced rectal cancer: A glimpse into the future.

Surgeons have grappled with the treatment of recurrent and T4b locally advanced rectal cancer (LARC) for many years. Their main objectives are to increase the overall survival and quality of life of the patients and to mitigate postoperative complications. Currently, pelvic exenteration (PE) with or without neoadjuvant treatment is a curative treatment when negative resection margins are achieved. The traditional open approach has been favored by many surgeons. However, the technological advancements in minimally invasive surgery have radically changed the surgical options. Recent studies have demonstrated promising results in postoperative complications and oncological outcomes after robotic or laparoscopic PE. A recent retrospective study entitled "Feasibility and safety of minimally invasive multivisceral resection for T4b rectal cancer: A 9-year review" was published in the World Journal of Gastrointestinal Surgery. As we read this article with great interest, we decided to delve into the latest data regarding the benefits and risks of minimally invasive PE for LARC. Currently, the small number of suitable patients, limited surgeon experience, and steep learning curve are hindering the establishment of minimally invasive PE.

Retroperitoneal Extension of a Fistula-in-Ano: A Case Report.

Fistula-in-ano and anorectal abscesses are commonly encountered in surgical departments, but their extension into the retroperitoneum and pelvis to form an extensive collection is rare. Here, we present the case of a 66-year-old diabetic male who presented with lower abdominal pain and fever for a day, with signs of sepsis. He had a simple fistula in the perianal region for the past 15 years. Radiological studies showed that the fistulous tract was complex which extended superiorly into the supralevator space and the retroperitoneum and formed a localized collection in the pelvis. The dependent part of the collection was drained using minimally invasive techniques, and the remnant collection was surgically drained through a perianal approach. The patient's condition improved with further treatment and local wound care, and he was subsequently discharged.

Impact of the endoscopic surgical skill qualification system on the oncological safety of laparoscopic gastrectomy for gastric cancer: A single-center retrospective cohort study.

BACKGROUND: This study aimed to investigate the laparoscopic gastrectomy (LG) performance of non-Endoscopic Surgical Skill Qualification System (ESSQS)-qualified surgeons under the ESSQS-qualified surgeon guidance and compare oncological outcomes of gastric cancer to LG performed by the ESSQS-qualified surgeons. METHODS: This study enrolled 1,030 patients diagnosed with both clinical and pathological stage ≤ III gastric cancer and undergoing LG from January 2009 to June 2019. ESSQS-qualified surgeons served as the operator or the instructive assistant in all LG procedures involving them. A propensity score-matched analysis was used to retrospectively compare the long-term outcomes between the ESSQS-qualified and non-ESSQS-qualified surgeons. RESULTS: Each group included 315 pairs after propensity score matching. The 3-year recurrence-free survival rates were 84.4% and 81.7% in the non-ESSQS and ESSQS groups, respectively. The difference was 2.7% (95% confidence interval: - 3.20%-8.44%, P < 0.001), and the non-ESSQS group statistically demonstrated noninferiority as the lower 95% confidence limit was greater than the prespecified margin of -10%, indicating the achieved primary endpoint. No significant differences in 5-year recurrence-free survival (non-ESSQS: 78.5% vs. ESSQS: 77.4%, P = 0.627) and 5-year overall survival (non-ESSQS: 80.9% vs. ESSQS: 79.3%, P = 0.475) were found between the two groups. The oncological outcomes stratified according to the presence of pathological stage I, II, and III disease did not significantly differ between the two groups. CONCLUSIONS: LG performed by non-ESSQS-qualified surgeons achieved comparable oncological outcomes to the ESSQS-qualified surgeons, as long as ESSQS-qualified surgeons provided intraoperative instructions, in a high-volume center.

The Application of Bidirectional Rapid Reductor in Minimally Invasive Plate Osteosynthesis for the Treatment of Proximal Humeral Fractures: A Case Series.

OBJECTIVE: Rapid and effective reduction is difficult for minimally invasive plate osteosynthesis (MIPO) surgery. This study aims to introduce a bidirectional rapid reductor (BRR) designed to assist in the reduction during MIPO surgery for proximal humeral fractures (PHFs). METHODS: This retrospective study was conducted between June 2021 and February 2022 in the Third Hospital of Hebei Medical University, involving patients diagnosed with PHFs. A detailed technical approach of BRR in MIPO surgery was described, and the patients' outcomes based on postoperative radiographic results including x-ray postoperative follow-up, and clinical outcome parameters including visual analogue scale (VAS) and constant-Murley score at last follow-up were reported. RESULTS: A total of 12 patients were included in this study, comprising three males and nine females, with an average age of 67.58 years. The mean operative time was 70.92 min (range 63-80 min). The mean blood loss was 102.27 mL (range 50-300 mL). The mean VAS and constant-Murley scores at final follow-up were 0.33 and 88, respectively. All patients had their fractures healed without secondary displacement at last follow-up. One patient experienced shoulder stiffness post-operation. There were no adverse events or complications following the use of this technique, such as acromion fracture, nerve or blood vessel injury. CONCLUSION: The BRR can assist MIPO for good reduction of PHFs. However, the efficacy should be validated with a large-sample randomized controlled trial and longer follow-up.

Use of Advanced Energy Devices and Fiberoptic Retractors in Single-Incision Breast-Conserving Surgery for Breast Cancer.

PURPOSE: The use of advanced energy devices for mastectomy and axillary lymph node dissection can reduce perioperative blood loss, seroma formation, and drainage duration/volume. Retraction using fiberoptic retractors can help visualize deep and narrow surgical fields. We aimed to compare the postoperative outcomes between single-incision breast-conserving surgery (SIBCS) and conventional breast-conserving surgery (CBCS) with axillary staging using advanced energy devices and conventional equipment, respectively. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 244 patients who underwent BCS with axillary surgery between March 2018 and September 2019 at Severance Hospital. The patients were grouped based on the device used to aid in axillary staging: CBCS group (n=117) used conventional electrocautery; and SIBCS group (n=127) used advanced energy devices and fiberoptic retractors. The two groups were compared for postoperative outcomes. RESULTS: The mean patient age was 55.9 and 53.1 years in the CBCS and SIBCS groups, respectively. Incision size was significantly smaller in the SIBCS group than in the CBCS group (6.3±2.1 cm vs. 7.5±2.5 cm, p=0.044). There were no significant differences between the two groups in terms of operating time (126.0±40.0 min vs. 127.0±63.0 min, p=0.828), operative blood loss (11.0±31.0 mL vs. 7.0±18.0 mL, p=0.100), drainage duration (7.0±3.0 d vs. 8.0±4.0 d, p=0.288), and complications (1.70% vs. 2.36%, p=0.523). CONCLUSION: Using advanced energy devices for SIBCS with axillary staging reduced incision size and provided better cosmetic outcomes compared to those using the conventional method. Advanced energy devices may offer better surgical outcomes in patients who undergo BCS with axillary staging.

Qualitative Evaluation of Paraspinal Musculature After Minimally Invasive Lumbar Decompression: A Prospective Study.

BACKGROUND: To quantify fatty infiltration and degree of paraspinal muscle degeneration in patients submitted to tubular microdiscectomy and conventional open microdiscectomy. METHODS: A prospective cohort of patients was submitted to microdiscectomy for lumbar disc herniation after failure of conservative treatment. Selection of the technique was based on the surgeon's preference. Analysis of the multifidus muscle was performed using the Goutallier system and the percentage of fat in the muscle. Preoperative and 1-year postoperative T2-weighted magnetic resonance imaging was used, and statistical analysis was carried out using the Wilcoxon test and Spearman correlation test using a significance level of 5%. RESULTS: Thirty-two patients were included in the study. The percentage of fatty infiltration in the muscle increased on both sides of the spine 1 year after surgery, although only the ipsilateral side presented statistical significance in patients submitted to conventional microdiscectomy (43.3% preoperative and 57.8% postoperative). Muscular degeneration increased significantly ipsilateral to the disc herniation according to the Goutallier classification (grades 1-2) for both interventions. No statistically significant difference was found for fatty infiltration scores or for the degree of muscular degeneration of the multifidus in the comparative analysis of the methods. CONCLUSIONS: Muscular damage resulting from surgery of lumbar disc herniation significantly increases fatty infiltration and degeneration of the multifidus. Muscular degeneration was associated with worsening back pain. CLINICAL RELEVANCE: While no significant difference was found between the techniques, the tubular minimally invasive approach shows a tendency for less muscle damage. These findings highlight the importance of minimizing muscle injury during surgery to improve postoperative recovery and long-term outcomes.

Minimally Invasive Glaucoma Surgery (MIGS) recommendations in Clinical Practice Guidelines for open angle glaucoma and MIGS procedures: A scoping review.

Introduction: To assess the recommendations of open angle glaucoma Clinical Practice Guidelines (CPG) addressing Minimally Invasive Glaucoma Surgery (MIGS) or MIGS procedures CPG. Methods: A scoping review of CPG was conducted, based on an ongoing systematic review (CRD42024510656). A systematic literature search of CPG was carried out in November 2023, with an update in January 2024. CPG published in the last 8 years, full text available and addressing MIGS were selected. CPG details and recommendations concerning MIGS were extracted. Results: 13 CPG addressing MIGS were selected (8 recovered from databases and 5 from registers). Four health Technology Assessments were assessed but recommendations were not considered. Finnish and Swedish guidelines, published in 2024, and Japanese guidelines, published in 2023, are English versions of their native language guidelines, but none of them make specific recommendations about MIGS. The Spanish Glaucoma Society - Advanced Glaucoma guideline (2023) describes the available techniques but does not make recommendations about MIGS. The European Glaucoma Society (2023) guideline only makes recommendations for 4 devices and the National Institute for Health and Care Excellence Interventional procedures guidance makes recommendations both for specific procedures and devices. Conclusion: MIGS is a relevant topic that has not been adequately addressed in terms of updated evidence, available procedures, and recommendations in open angle glaucoma CPG or MIGS procedures CPG.

Screw Stimulation Thresholds for Neuromonitoring in Minimally Invasive Oblique Lateral Lumbar Interbody Fusion (OLLIF): A Correlational Study.

INTRODUCTION: This study presents findings from an investigation into the correlation of neuromonitoring techniques in minimally invasive lumbar fusions and their open counterparts regarding acceptable thresholds for screw stimulation. The threshold for acceptable stimulation value for open surgery has been established. The study compared acceptable thresholds for open pedicle screws where there is more connection between the screw and the soft tissue. METHODS: The neuromonitoring data of 17 patients who underwent oblique lateral lumbar interbody fusion (OLLIF) procedures between September 2023 to May 2024 were reviewed. Neuromonitoring was conducted throughout surgeries, recording stimulation thresholds for pedicle screws insulated and uninsulated, to simulate the environment of a screw during open and minimally invasive surgery respectively. Patients' BMI was also collected for potential correlation analysis. RESULTS: Results indicate a discernible correlation between stimulation thresholds in open and minimally invasive surgeries, but no definitive correlation with BMI due to sample size limitations. Though a significant correlation between the two stimulating styles is apparent, there is a good correlation to suggest what threshold should determine a standard stimulation threshold for minimally invasive surgeries. CONCLUSION: The study emphasizes the need for refined neuromonitoring strategies in minimally invasive spinal fusion (MISF) surgeries to ensure patient safety and surgical effectiveness. Further research with larger cohorts is recommended to establish optimized protocols that have a clearly defined amplitude for MISF thresholds.

Salvage High-Intensity Focused Ultrasound for Prostate Cancer after Radiation Failure: A Narrative Review.

For patients diagnosed with localized prostate cancer, there are multiple treatment options available. The traditional treatment modalities include radical prostatectomy and radiotherapy. Nevertheless, focal therapy, including high-intensity focused ultrasound (HIFU) and cryotherapy, has emerged as a less-invasive method in this setting. Some patients undergoing primary radiation therapy experience recurrence, but there is currently no consensus on the optimal approach for salvage treatment in such cases. The lack of robust data and randomized controlled trials comparing different whole-gland and focal salvage therapies presents a challenge in determining the ideal treatment strategy. This narrative review examines the prospective and retrospective data available on salvage HIFU following radiation therapy. Based on the literature, salvage HIFU for radio-recurrent prostate cancer has promising oncological outcomes, with an overall 5-year survival rate of around 85%, as well as incontinence rates of about 30% based on the patient's risk group, follow-up times, definitions used, and other aspects of the study. Salvage HIFU for prostate cancer proves to be an effective treatment modality for select patients with biochemical recurrence following radiotherapy.
