Laryngeal leiomyoma: A case report and review of literature.

BACKGROUND: Leiomyomas (LMs) are mesenchymal tumors that arise from smooth muscle cells. LMs most commonly arise in organs with an abundance of smooth muscle such as the uterus and gastrointestinal tract. Conversely, LMs are rarely detected in the head and neck region. In this study, we report a rare case of laryngeal LM (LLM) and summarized the clinical characteristics of reported LLMs to help clinicians better understand this rare disease and improve its diagnosis, treatment, and postoperative course. CASE SUMMARY: A 49-year-old man was admitted to our ENT outpatient clinic with a chief complaint of pharynx discomfort for 2 months. Laryngoscopy performed under topical anesthesia revealed a solitary, pink mass at the tubercle of epiglottis. Surgery via laryngeal endoscopy was performed under general anesthesia, and the lesion was excised easily. Positive immunohistochemical staining for desmin and smooth-muscle actin indicated a smooth muscle origin and the diagnosis was laryngeal leiomyoma. After surgery, the patient's condition was stable, and he was discharged 2 d after surgery. During the 1-year postoperative period, the patient's condition remained stable without evidence of recurrence. CONCLUSION: Surgical resection is the preferred treatment for LLMs, its early diagnosis and differential diagnosis have important clinical significance.

Effect of nursing intervention on rehabilitation of patients with chronic sinusitis and nasal polyps after nasal endoscopy.

BACKGROUND: Chronic sinusitis is a kind of chronic suppurative inflammation of the sinus mucosa. Nasal endoscopy is a good method to treat nasal polyps. However postoperative rehabilitation and care should not be neglected. AIM: To investigate the Effect of nursing intervention on the rehabilitation of patients with chronic sinusitis and nasal polyps (CSNPS) after nasal endoscopy. METHODS: A total of 129 patients with CSNPS hospitalized from February 2017 to February 2019 were studied. Using the digital parity method, we investigated nursing cooperation strategies for endoscopic surgery. The comparison group (64 cases): Surgical nursing was carried out with traditional nursing measures; experimental group (65 cases): Surgical nursing was carried out by traditional nursing countermeasures + comprehensive nursing measures. We compared postoperative recovery rates, nursing satisfaction rates, and nasal cavity ratings between the two groups. RESULTS: Experimental group patients with CSNPS had a significantly higher recovery rate (98.46%) compared to the control group (79.69%). This difference was statistically significant (χ 2 = 11.748, P < 0.05). Additionally, the satisfaction rate with treatment was also significantly higher in the experimental group (98.46%) compared to the control group (79.69%), with a statistically significant difference (χ 2 = 11.748, P < 0.05). Before nursing, there was no significant difference in sinus nasal cavity scores between the experimental group (20.29 ± 7.25 points) and the control group (20.30 ± 7.27 points) (t = 0.008, P > 0.05). However, after nursing, the sinus nasal cavity score in the experimental group (8.85 ± 3.22 points) was significantly lower than that in the control group (14.99 ± 5.02 points) (t = 8.282, P < 0.05). CONCLUSION: Comprehensive nursing intervention in patients with CSNPS can significantly improve the total recovery rate after endoscopic surgery.

Adoption of vaginally assisted natural orifice transluminal endoscopic surgery for hysterectomy: A single tertiary experience.

BACKGROUND: Vaginal hysterectomy (VH) rate is declining despite being considered as the optimal minimally invasive option for hysterectomy with reduced operative time and length of stay compared with laparoscopic hysterectomy (LH). Vaginal assisted natural orifice transluminal endoscopic surgery hysterectomy (VANH) combines the advantages of both vaginal and endoscopic approach to surgery. AIMS: To report feasibility and early experience of a single surgeon adopting VANH at a tertiary Australian hospital. MATERIALS AND METHODS: Prospective review of the first 20 VANH cases with complete data set collected retrospectively including patient demographics, indication for surgery and perioperative outcomes. RESULTS: The median age of the first 20 participants was 51.5 years (47-57 years of age) and the median body mass index was 33.5 kg/m2 (27.8-38.3 kg/m2). The predominant indication was complex hyperplasia with atypia (12/20, 60%). The median parity was two (1-3) where four patients were nulliparous. The median blood loss was 125 mL (100-200 mL) with an operative time of 149 min (138-198 min) and median weight of the specimen of 181.5 g (66.5-219 g). The mean length of stay was 1.4 days (1-2 days). Five cases had conversion to laparoscopy and the majority (80%) occurred within the first ten cases. CONCLUSIONS: VANH is feasible but there is a learning curve to achieve competence in this technique, which requires adequate training in the early stages of adoption with careful case selection. Until further robust data is available to determine the clinical benefit and safety profile of VANH, patients should be carefully counselled and the decision on mode of hysterectomy be individualised.

A Case of Endoscopic Partial Transverse Process and Sacral Alar Resection for Bertolotti's Syndrome and Continued Basketball Playing Two Years After Surgery.

Bertolotti's syndrome is a syndrome in which the transverse process of the most caudal lumbar vertebra becomes enlarged and articulates with the sacral alar, causing back pain. Here, we report a case of an adolescent basketball player with Bertolotti's syndrome who was unable to resume playing despite conservative treatment and underwent an endoscopic partial transverse process and sacral alar resection. A 16-year-old male basketball player presented to our hospital with a chief complaint of left low back pain during exercise and prolonged sitting for over one month. No obvious neurological abnormality was found. X-rays and CT showed lumbosacral transitional vertebrae, and the left transverse process of the sixth lumbar vertebra articulated with the sacrum and iliac, which was the Castellvi classification IIA. A block injection into the articulated surface produced improvement in pain, but the effect was not sustained. Since the patient was refractory to conservative treatments, such as medication and physiotherapy, surgery was performed. During surgery, the articulated transverse process and sacral alar were partially resected endoscopically. Because of the proximity of the resection site to the S1 nerve root, intraoperative electromyography (free-run EMG) was used to detect nerve root irritation symptoms in real time. The patient had no postoperative complications, his low back pain improved immediately, and he returned to play basketball three months after surgery. One year after surgery, the bone resection site showed gradual bone regeneration, and two years after surgery, the transverse process and sacral alar showed a bony bridge. The transverse process was enlarged compared to immediately after surgery but remained smaller than that before surgery. The patient continued to play basketball for two years after surgery without back pain, and no symptoms due to bone regeneration appeared. In the present case, a partial resection of the transverse process and sacral alar was performed with good results. Because the bone resection site was close to the S1 nerve root, the use of an endoscope and intraoperative free-run EMG allowed for a safer procedure during the bone resection. In addition, the patient did not present with symptoms that would affect his basketball performance, although the bone regenerated and bridging occurred between the transverse process and sacral alar over a two-year postoperative course.

A Convoy of Magnetic Millirobots Transports Endoscopic Instruments for Minimally-Invasive Surgery.

Small-scale robots offer significant potential in minimally invasive medical procedures. Due to the nature of soft biological tissues, however, robots are exposed to complex environments with various challenges in locomotion, which is essential to overcome for useful medical tasks. A single mini-robot often provides insufficient force on slippery biological surfaces to carry medical instruments, such as a fluid catheter or an electrical wire. Here, for the first time, a team of millirobots (TrainBot) is reported to generate around two times higher actuating force than a TrainBot unit by forming a convoy to collaboratively carry long and heavy cargos. The feet of each unit are optimized to increase the propulsive force around three times so that it can effectively crawl on slippery biological surfaces. A human-scale permanent magnetic set-up is developed to wirelessly actuate and control the TrainBot to transport heavy and lengthy loads through narrow biological lumens, such as the intestine and the bile duct. The first electrocauterization performed by the TrainBot is demonstrated to relieve a biliary obstruction and open a tunnel for fluid drainage and drug delivery. The developed technology sheds light on the collaborative strategy of small-scale robots for future minimally invasive surgical procedures.

Surgical therapy in advanced sinonasal carcinomas - retrospective study.

BACKGROUND AND AIM: Sinonasal tumors are a rare and heterogeneous group of malignant tumors with different histopathological characteristics and clinical presentation. These tumors are usually treated through surgery. The aim of this study is to present our results of surgical therapy in patients with an advanced sinonasal tumor. METHODS: This retrospective study included patients with an advanced sinonasal tumor who were surgically treated. The surgical technique combined both a frontal transbasal approach together with an endoscopic endonasal approach. The parameters used for evaluation were the histological type of tumor, the radicality of resection (complete vs. incomplete), the frequency of recurrence, the surgical and postoperative complications, the type of subsequent oncological therapy and the overall survival. RESULTS: The group consisted of ten patients seven were men and three were women. Complete resection (defined as R0) was achieved in 8 (80%) of the cases, subcomplete resection was achieved in 2 (20%) of the cases. The overall survival period was 28.7 months (95% confidence interval 15.9-41.6). CONCLUSION: The combination of the frontal transbasal approach with the endoscopic endonasal approach is a suitable surgical strategy that enables easier achievement of complete tumor resection, reconstruction of the anterior skull base and reduces the need for extensive surgical approaches.

Analysis of quality of life in patients after transgastric natural orifice transluminal endoscopic gallbladder-preserving surgery.

BACKGROUND: At present, laparoscopic cholecystectomy (LC) is the main surgical treatment for gallstones. But, after gallbladder removal, there are many complications. Therefore, it is hoped to remove stones while preserving the function of the gallbladder, and with the development of endoscopic technology, natural orifice transluminal endoscopic surgery came into being. AIM: To compare the quality of life, perioperative indicators, adverse events after LC and transgastric natural orifice transluminal endoscopic gallbladder-preserving surgery (EGPS) in patients with gallstones. METHODS: Patients who were admitted to The First Affiliated Hospital of Xinjiang Medical University from 2020 to 2022 were retrospectively collected. We adopted propensity score matching (1:1) to compare EGPS and LC patients. RESULTS: A total of 662 cases were collected, of which 589 cases underwent LC, and 73 cases underwent EGPS. Propensity score matching was performed, and 40 patients were included in each of the groups. In the EGPS group, except the gastrointestinal defecation (P = 0.603), the total score, physical well-being, mental well-being, and gastrointestinal digestion were statistically significant compared with the preoperative score after surgery (P < 0.05). In the LC group, except the mental well-being, the total score, physical well-being, gastrointestinal digestion, the gastrointestinal defecation was statistically significant compared with the preoperative score after surgery (P < 0.05). When comparing between groups, gastrointestinal defecation had significantly difference (P = 0.002) between the two groups, there was no statistically significant difference in the total postoperative score and the other three subscales. In the surgery duration, hospital stay and cost, LC group were lower than EGPS group. The recurrence factors of gallstones after EGPS were analyzed: and recurrence was not correlated with gender, age, body mass index, number of stones, and preoperative score. CONCLUSION: Whether EGPS or LC, it can improve the patient's symptoms, and the EGPS has less impact on the patient's defecation. It needed to, prospective, multicenter, long-term follow-up, large-sample related studies to prove.

Anatomical Measurement as a Reference for Functional Endoscopic Sinus Surgery Based on CT Scans and Dissections.

Introduction Diseases of the paranasal sinuses, nasal cavities, and those related to the skull base can be treated with nasal endoscopic surgery. Anatomical references are essential to safely perform these surgeries. Objective To measure and compare the distance from the posterior wall of the maxillary sinus to the anterior skull base in cadavers and on computed tomography (CT) scans to determine a measurement as an anatomical reference in imaging exams for sinus and anterior skull base surgery. Methods In dissections and CT scans, we took measurements from the most upper and medial point of the posterior wall of the maxillary sinus (point A) to the point where the skull base deflects and the anterior sphenoid wall is formed (Δ 90°; point B), in the right and left nasal cavities. We used 51 cadavers aged ≥ 18 years in the present research. Results The measurements obtained from CT scans and dissections were greater than 1.5 cm in all cadavers, and they were positively correlated. The 1-cm increase in the AB-tomography measurement corresponded to the 1.08-cm increase to the right and 1.07-cm to the left in the AB-dissection measurement. Conclusion The CT measurements may be considered a reliable tool to promote safe and effective access to the paranasal sinuses, matching the distance that should be dissected until the anterior base of the skull.

Endoscopic trans-orbital approach for the tumor-related epilepsy at the temporal tip.

Minimally invasive surgery is gaining increasing interest in epilepsy surgery. In this video, the authors present the endoscopic transorbital approach for an epileptogenic lesion located at the temporal tip. The patient was a man in his 40s who has had intractable focal impaired awareness seizures and focal to bilateral tonic-clonic seizures since he was 31 years of age. According to the preoperative examination, including stereotactic electroencephalography, a cavernous angioma located at the tip of the right temporal lobe was diagnosed as an epileptogenic lesion. Lesionectomy for this lesion was performed using the endoscopic transorbital approach as minimally invasive surgery and a favorable outcome was achieved. The video can be found here: https://stream.cadmore.media/r10.3171/2024.4.FOCVID2414.

Full endoscopic percutaneous stenoscopic lumbar decompression and discectomy: An outcome and efficacy analysis on 606 lumbar stenosis patients.

Introduction: Laminectomy has long been a "gold standard" to treat symptomatic lumbar spinal stenosis (LSS). Minimal invasive spine surgery (MISS) is widely developed to overcome the limitations of conventional laminectomy to achieve a better outcome with minimal complications. Full endoscopic percutaneous stenoscopic lumbar decompression (FE-PSLD) is the newest MISS technique for spinal canal decompression. We aimed to evaluate and analyze the significance of FE-PSLD in reducing pain and its association with age, duration of symptoms, stenosis level, and operative time (OT). Materials and Methods: A longitudinal cross-sectional study was conducted on 606 LSS patients who underwent FE-PSLD and enrolled from 2020 to 2022. Three-month evaluation of the Visual Analog Scale (VAS) and the modified MacNab criteria were assessed. The significance of changes was analyzed using the Wilcoxon signed-ranks test. Spearman's correlation test was performed to evaluate the significant correlation of several variables (pre-PSLD-VAS, age, symptoms duration, OT, and level of LSS) to post-PSLD-VAS, and multiple regression analysis was conducted. Results: The reduction of VAS was statistically significant (P ≤ 0.005) with an average pre-PSLD-VAS of 6.75 ± 0.63 and post-PSLD-VAS of 2.24 ± 1.04. Pre-PSLD-VAS, age, and stenosis level have a statistically significant correlation with post-PSLD-VAS, while the duration of the symptoms and OT have an insignificant correlation. Multiple regression showed the effect of pre-PSLD-VAS (ß =0.4033, P = 0.000) and stenosis level (ß =0.0951, P = 0.021) are statistically significant with a positive coefficient. Conclusions: FE-PSLD is an efficacious strategy with favorable outcomes for managing LSS, shown by a significant reduction of pain level with a relatively short follow-up time after the procedure. Preoperative pain level, age, and stenosis level are significantly correlated with postoperative pain level. Based on this experimental study, PSLD can be considered a good strategy for treating lumbar canal stenosis in all age groups and all LSS levels.

Transoral snare removal of subepiglottic cysts.

OBJECTIVE: The objective of this demonstration was to describe and simulate a surgical technique for removing subepiglottic cysts in horses via an oral approach under endoscopic guidance using a cadaver model for simulation and clinical data. The technique aims to provide a minimally invasive method for the removal of these cysts. ANIMALS: 2 clinical case images from the Washington State University Teaching Hospital were used in the video. In a third horse euthanized for reasons unrelated to the study, the procedure was simulated after the head was frozen and transected transversally. METHODS: Files from 2 horses were reviewed, and the relevant parts were selected. The horse head was set on a stand, and a simulated cyst was implanted under the mucosa, made of the fingertip from a glove filled with carboxymethyl cellulose gel, and sutured. The procedure was performed by one of the authors (CAR) and recorded. A bronchoesophageal grasping forceps and cautery snare were used to simulate a clinical situation in dorsal recumbency. RESULTS: The cyst was successfully removed as in the real procedure, and the demonstration was recorded for educational use. The review of the videos shows that the simulated procedure is also achievable in a real clinical environment. CLINICAL RELEVANCE: This technique provides a minimally invasive method for the removal of subepiglottic cysts in horses. The demonstration of this procedure is crucial for the training of surgeons, as it allows the visualization of the procedure in a controlled setting, free from the complications of real clinical situations.

Endoscopic and exoscopic surgery for brain tumors.

Nerves and blood vessels must be protected during brain tumor surgery, which has traditionally relied on microscopes. In the 2000s, endoscopes and related equipment were developed for neurosurgery. In this review, we aim to outline the role of endoscopes in brain tumor surgery and discuss the emerging use of exoscopes. The primary use of endoscopes in brain tumor surgery is in endoscopic endonasal surgery for pituitary tumors. By using the space within the sphenoid sinus, surgeons can insert an endoscope and instruments such as forceps or scissors through the nose to access and remove the tumor. Compared to microscopes, endoscopes can get closer to tumors, nerves, and blood vessels. They enable wide-angle observation of the skull base, making them valuable for skull base tumors as well as pituitary tumors. Endoscopes are also used in cases where a brain tumor is associated with hydrocephalus, allowing surgeons to correct obstructive hydrocephalus and perform tumor biopsies simultaneously. Exoscopy, a newer technique introduced in recent years, involves surgeons wearing special glasses and removing the tumor while viewing a three-dimensional monitor. This approach reduces surgeon fatigue and allows for more natural positioning during lengthy brain tumor surgeries. Future brain tumor surgeries will likely involve robotic surgery, which is already used for other organs. This is expected to make brain tumor removal safer and more accurate.

Multiportal Retrograde Endoscopy to Enhance Surgical Target Visualization: A Pilot Study.

Objective Current transnasal endoscopic techniques for sinus and skull base surgery use a single endoscope to provide visualization from one perspective curtailing depth perception and compromising visualization of the instrument-target interface. The view can be blocked by instruments, and collisions between instruments often occur. The objective of this study was to investigate the use of multiportal retrograde endoscopy to provide more accurate manipulation of the surgical target. Design Maxillary antrostomy and frontal sinusotomy were performed on three different cadavers by three different surgeons. A zero-degree rigid endoscope was introduced through the nose for the standard transnasal approach. A flexible endoscope was introduced transorally, directed past the palate superiorly, and then flexed 180 degrees for the retrograde view. Videos of the standard transnasal view from the rigid endoscope and retrograde view from the flexible endoscope were recorded simultaneously. Results All surgeries were able to be performed with dual-screen viewing of the standard and retrograde view. The surgeons noted that they utilized the retrograde view to adjust the location of ends/tips of their instruments. Four surgeons reviewed the videos and individually agreed that the visualization achieved provided a perspective otherwise not attainable with rigid transnasal endoscopy alone. Conclusion High-quality visualization of surgical targets such as the frontal or maxillary ostia can be challenging with rigid endoscopes alone. Multiportal retrograde endoscopy provides proof of concept that additional views of a surgical target can be achieved. Additional work is needed to further develop indications, techniques, and generalizability to targets beyond those investigated here.

The impact of obesity on rates of post-operative CSF leak following endoscopic skull base surgery: results from a prospective international multi-centre cohort study.

Aims: Post-operative CSF leak is the major source of morbidity following transsphenoidal approaches (TSA) and expanded endonasal approaches (EEA) to lesions of the sella turcica and the ventral skull base. There are conflicting reports in the literature as to whether obesity (BMI ≥30) is a risk factor for this complication. We aimed to evaluate data collected as part of prospective multi-centre cohort study to address this question. Methods: The CRANIAL (CSF Rhinorrhoea After Endonasal Intervention to the Skull Base) study database was reviewed and patients were divided into obese and non-obese cohorts. Data on patient demographics, underlying pathology, intra-operative findings and skull base repair techniques were analysed. Results: TSA were performed on 726 patients, of whom 210 were obese and 516 were non-obese. The rate of post-operative CSF leak in the obese cohort was 11/210 (5%), compared to 17/516 (3%) in the non-obese cohort, which was not statistically significant (χ2 = 1.520, p=0.217). EEA were performed on 140 patients, of whom 28 were obese and 112 were non-obese. The rate of post-operative CSF leak in the obese cohort was 2/28 (7%), which was identical to the rate observed in the non-obese cohort 8/112 (7%) Fisher's Exact Test, p=1.000). These results persisted following adjustment for inter-institutional variation and baseline risk of post-operative CSF leak. Conclusion: CSF leak rates following TSA and EEA, in association with modern skull base repair techniques, were found to be low in both obese and non-obese patients. However, due to the low rate of post-operative CSF leak, we were unable to fully exclude a small contributory effect of obesity to the risk of this complication.

Can we encourage the endoscopic treatment for external snapping hip (ESH)? A systematic review of current concepts.

BACKGROUND: Snapping hip syndrome (SHS) is characterized by snapping sensation and pain and affects up to 10% of the general population. External snapping hip syndrome (ESHS), the most common form, is often due to repetitive movements in sports or anatomical predispositions. Conservative treatment includes physiotherapy and corticosteroid injections, while surgery is considered if conservative measures fail. Open surgical techniques carry several risks, while modern arthroscopic techniques offer less invasive options, such as endoscopic iliotibial band release (ITB) and gluteus maximus tenotomy. MATERIALS AND METHODS: A systematic review was conducted adhering to the PRISMA guidelines. Relevant studies were searched in four databases: Pubmed, Scopus, Embase, and Medline. The selected articles were evaluated according to the criteria of levels of evidence. The Risk of Bias In Non-randomized Studies of Interventions (ROBINS-I) was used to analyze the retrospective studies. This paper was registered in the International Prospective Registry of Systematic Reviews (PROSPERO). RESULTS: Out of 9 included studies, 403 patients with 689 hips underwent endoscopic treatment. ITB release and his variations were the main surgical techniques. Gluteus maximus tenotomy was also used in some studies. Postoperative rehabilitation protocols varied. Patients generally experienced significant improvements in symptoms and functional outcomes, with low rates of recurrence (1.02%) and revision (0.15%). Complications were minimal. CONCLUSIONS: Endoscopic treatment of ESH shows favorable results, improving functional outcomes and returning patients to pre-injury activity levels. Long-term efficacy and costeffectiveness need to be evaluated, emphasizing the importance of large-scale prospective randomized trials to clarify surgery's benefits in refractory ESH cases.

Sentinel Lymph Node Mapping by Retroperitoneal vNOTES for Uterus-Confined Malignancies: A Standardized 10-Step Approach.

(1) Background: Sentinel lymph node (SLN) mapping represents an accurate and feasible technique for the surgical staging of endometrial and cervical cancer. This is commonly performed by conventional laparoscopy or robotic-assisted laparoscopy, but in recent years, a new retroperitoneal transvaginal natural orifice transluminal endoscopic surgery (vNOTES) approach has been described and developed by Jan Baekelandt. This technique provides easy visualization of lymphatic afferent vessels and pelvic lymph nodes, early SLN assessment, and a coherent mapping methodology following the lymphatic flow from caudal to cranial. However, only a few publications have reported it. Following the IDEAL (Idea Development Exploration Assessment Long-term follow-up) framework, research concerning this technique is in Stage 2a, with only small case series as evidence of its feasibility. Its standardized description appears necessary to provide the surgical homogeneity required to move further. (2) Methods: Description of a standardized approach for retroperitoneal pelvic SLN mapping by vNOTES. (3) Results: We describe a 10-step approach to successfully perform retroperitoneal vNOTES SLN mapping, including pre-, intra-, and postoperative management. (4) Conclusions: This IDEAL Stage 2a study could help other surgeons approach this new technique, and it proposes a common methodology necessary for evolving through future IDEAL Stage 2b (multi-center studies) and Stage 3 (randomized controlled trials) studies.

Minimally invasive surgeries for spontaneous hypertensive intracerebral hemorrhage (MISICH): a multicenter randomized controlled trial.

BACKGROUND: Intracerebral hemorrhage (ICH) is a common stroke type with high morbidity and mortality. There are mainly three surgical methods for treating ICH. Unfortunately, thus far, no specific surgical method has been proven to be the most effective. We carried out this study to investigate whether minimally invasive surgeries with endoscopic surgery or stereotactic aspiration (frameless navigated aspiration) will improve functional outcomes in patients with supratentorial ICH compared with small-bone flap craniotomy. METHODS: In this parallel-group multicenter randomized controlled trial conducted at 16 centers, patients with supratentorial hypertensive ICH were randomized to receive endoscopic surgery, stereotactic aspiration, or craniotomy at a 1:1:1 ratio from July 2016 to June 2022. The follow-up duration was 6 months. Patients were randomized to receive endoscopic evacuation, stereotactic aspiration, or small-bone flap craniotomy. The primary outcome was favorable functional outcome, defined as the proportion of patients who achieved a modified Rankin scale (mRS) score of 0-2 at the 6-month follow-up. RESULTS: A total of 733 patients were randomly allocated to three groups: 243 to the endoscopy group, 247 to the aspiration group, and 243 to the craniotomy group. Finally, 721 patients (239 in the endoscopy group, 246 in the aspiration group, and 236 in the craniotomy group) received treatment and were included in the intention-to-treat analysis. Primary efficacy analysis revealed that 73 of 219 (33.3%) in the endoscopy group, 72 of 220 (32.7%) in the aspiration group, and 47 of 212 (22.2%) in the craniotomy group achieved favorable functional outcome at the 6-month follow-up (P = .017). We got similar results in subgroup analysis of deep hemorrhages, while in lobar hemorrhages the prognostic outcome was similar among three groups. Old age, deep hematoma location, large hematoma volume, low preoperative GCS score, craniotomy, and intracranial infection were associated with greater odds of unfavorable outcomes. The mean hospitalization expenses were ¥92,420 in the endoscopy group, ¥77,351 in the aspiration group, and ¥100,947 in the craniotomy group (P = .000). CONCLUSIONS: Compared with small bone flap craniotomy, endoscopic surgery and stereotactic aspiration improved the long-term outcome of hypertensive ICH, especially deep hemorrhages.

Shaping the curve from the microscopic transsphenoidal to the endoscopic endonasal approach for the sellar region.

OBJECTIVE: This study aimed to investigate the limitations, barriers, and complications in the early transition from the microscopic transsphenoidal approach (MTA) to the endonasal endoscopic approach (EEA) to the skull base in our institution. METHODS: Technical challenges, as well as clinical features and complications, were compared between MTA, EEA, and mixed cases during the early surgical curve. RESULTS: The period from the early learning curve was 1 year until the EEA protocol was used routinely. A total of 34 patients registered a resection using a transsphenoidal approach. Eighteen patients underwent EEA, 11 underwent MTA, and five underwent a mixed endonasal and microscopic approach. Non-significant differences were found in endocrine outcomes between the three groups. Patients with unchanged or improved visual function were higher in the EEA group (p = 0.147). Non-significant differences were found in terms of the extent of resection (EOR) between groups (p = 0.369). Only 1 (2.9%) patient in the whole series developed a post-operative CSF leaking that resolved with medical management, belonging to the EEA group (5.5%). CONCLUSIONS: The early phase of the learning curve did not affect our series significantly in terms of the EOR, endocrine status, and visual outcomes.

OBJETIVO: Investigar las limitaciones, las barreras y las complicaciones en la transición del abordaje transesfenoidal microscópico (ATM) al abordaje endonasal endoscópico (AEE) para la base del cráneo en nuestra institución. MÉTODO: Se compararon las características clínicas y las complicaciones entre ATM, AEE y casos mixtos durante la curva quirúrgica temprana. RESULTADOS: El periodo desde la curva de aprendizaje inicial fue de 1 año hasta que se utilizó el protocolo AEE de forma sistemática. Un total de 34 pacientes tuvieron una resección por vía transesfenoidal. A 18 pacientes se les realizó AEE, a 11 ATM y a 5 abordaje mixto endonasal y microscópico. Se encontraron diferencias no significativas en los resultados endocrinos entre los tres grupos. Los pacientes con función visual sin cambios o mejorada fueron más en el grupo AEE (p = 0.147). No se encontraron diferencias significativas respecto a la extensión de la resección (p = 0.369). Solo 1 (2.9%) paciente desarrolló una fístula de líquido cefalorraquídeo que se resolvió con manejo médico, perteneciente al grupo AEE (5.5%). CONCLUSIONES: La fase inicial de la curva de aprendizaje no afectó significativamente a nuestra serie en términos de extensión de la resección, estado endocrino y resultados visuales.

Endoscopic management of greater trochanteric pain syndrome (GTPS): a comprehensive systematic review.

BACKGROUND: Greater trochanteric pain syndrome (GTPS) presents challenges in clinical management due to its chronic nature and uncertain etiology. Historically attributed to greater trochanteric bursitis, current understanding implicates abductor tendinopathy as the primary cause. Diagnosis usually involves a clinical examination and additional tests such as imaging and provocative testing. Surgical intervention may be considered for cases refractory to conservative therapy, with endoscopic techniques gaining ground over open procedures. MATERIALS AND METHODS: A systematic review was conducted adhering to the PRISMA guidelines. Relevant studies were searched in four databases: Pubmed, Scopus, Embase, and Medline. The selected articles were evaluated according to the criteria of levels of evidence (LoE). The Coleman methodology score (mCMS) was used to analyze the retrospective studies. This systematic review was registered in the International Prospective Registry of Systematic Reviews. RESULTS: Surgical success rates ranged from 70.6-100%, significantly improving pain and function. Complications were generally mild, mainly hematomas and seromas, while recurrence rates were low. However, limitations such as the retrospective design and the absence of control groups warrant cautious interpretation of the results. CONCLUSIONS: Endoscopic surgery emerges as a promising option for refractory GTPS, offering effective symptom relief and functional improvement. Despite limitations, these results suggest a favorable risk-benefit profile for endoscopic procedures. Further research is needed, particularly prospective randomized trials, to confirm these findings and optimize surgical techniques to improve patient outcomes.
