Ablative minimally invasive surgical therapies for benign prostatic hyperplasia: A review of Aquablation, Rezum, and transperineal laser prostate ablation.

INTRODUCTION: Benign prostatic hyperplasia (BPH) is one of the most common diseases affecting men and can present with bothersome lower urinary tract symptoms (LUTS). Historically, transurethral resection of the prostate (TURP) has been considered the gold standard in the treatment of LUTS due to BPH. However, TURP and other traditional options for the surgical management of LUTS secondary to BPH are associated with high rates of sexual dysfunction. In the past decade, several novel technologies, including Aquablation therapy, convective water vapor therapy (Rezum), and transperineal prostate laser ablation (TPLA), have demonstrated promising evidence to be safe and effective while preserving sexual function. METHODS: In this review, we discuss three ablative minimally invasive surgeries: Aquablation, Rezum, and TPLA. We review their techniques, safety, as well as perioperative and functional outcomes. We go into further detail regarding sexual function after these ablative minimally invasive surgical therapies. RESULTS: Aquablation is a surgeon-guided, robot-executed, heat-free ablative waterjet procedure with sustained functional outcomes at 5 years while having no effect on sexual activity. Rezum is an innovative office-based, minimally invasive surgical option for BPH that delivers convective water vapor energy into prostate adenoma to ablate obstructing tissue. Rezum leads to significant improvements in Qmax, IPSS while preserving sexual function. TPLA is another office-based technology which uses a diode laser source to produce thermoablation. It leads to improvement in Qmax, IPSS, and QoL while preserving ejaculatory function. CONCLUSIONS: Overall, ablative minimally invasive surgical therapies have demonstrated excellent safety and efficacy profiles while preserving sexual function. These modalities should be discussed with patients to ensure informed and shared decision-making. Ablative minimally invasive surgical therapies may be particularly interesting to patients who value the preservation of their sexual function.

Transanal minimally invasive surgery for benign and malignant rectal lesions: midterm outcomes from a tertiary center.

BACKGROUND: Although transanal minimally invasive surgery (TAMIS) for rectal neoplasia has gained wide acceptance, the mid-term and long-term outcomes are not widely reported in the literature. OBJECTIVE: Describe the mid-term outcomes of patients who underwent TAMIS for benign and malignant rectal lesions in a single center. DESIGN: Retrospective cohort study. SETTINGS: Tertiary referral center. PATIENTS AND METHODS: Demographic, clinical, and oncological outcomes of patients who underwent TAMIS between January 2015 and December 2022 were prospectively collected. The indication for TAMIS was based on the National Comprehensive Cancer Network guidelines. The follow up for the cancer patients included clinical examination, tumor markers every 6 months and MRI rectum at the end of one year. In addition, colonoscopy and CT scan at years one and three and a final CT scan and colonoscopy at year five. MAIN OUTCOME MEASURES: Mid-term oncological and clinical outcome. RESULTS: Thirty elective TAMIS procedures included adenocarcinoma for 33.3% (n=10) of the patients, 20% (n=6) neuroendocrine tumor and the 40% (n=12) were adenomatous lesions. Negative resection margins were achieved in all malignant lesions. Perioperative complications occurred in 2 patients (6.6%), one patient had breaching into the peritoneal cavity, and postoperative hypotension occurred in another patient. The median follow-up time was 23 months (range: 5-72 months). Two patients with adenoma and positive margins developed recurrent adenoma (6.6%) and one patient with initial polypectomy biopsy of adenocarcinoma, had TAMIS with histopathology of adenoma and distant metastasis had developed. CONCLUSIONS: TAMIS for local excision of rectal neoplasia is a valid option with favorable mid-term outcomes provided there is adherence to careful selection criteria. LIMITATIONS: Retrospective nature and small number of the patients.

Clinical Study of Percutaneous Endoscopic Large-channel Fusion and Transforaminal Lumbar Interbody Fusion in the Treatment of Degenerative Lumbar Spinal Stenosis.

Context: Degenerative changes in the lumbar spine more commonly cause spinal stenosis and with the aging of society, its incidence is on the rise. Endoscopic spinal surgery is a minimally invasive technique for decompression. The efficacy of percutaneous, endoscopic, large-channel fusion and transforaminal lumbar interbody fusion (TLIF) need confirmation by more studies. Objective: The study intended to investigate the clinical efficacy of percutaneous endoscopic large-channel fusion and TLIF in the treatment of degenerative lumbar spinal stenosis, to find the best treatment plan. Design: The research team performed a retrospective study. Setting: The study took place at Nanjing Lishui People's Hospital in Nanjing, Jiangsu Province, PR China. Participants: Participants were 100 patients with degenerative, lumbar, spinal stenosis who had been admitted to the hospital between October 2018 and October 2022. Intervention: The research team randomly divided participants into an intervention group and a control group, with 50 participants in each group. The intervention group received percutaneous, endoscopic, large-channel fusion and internal fixation, and the control group received foraminal, lumbar, interbody fusion. Outcome Measures: The research team measured: (1) perioperative indexes, (2) clinical efficacy at a postoperative follow-up at 6 months postintervention, (3) indexes for inflammatory responses at baseline and postintervention, (4) postoperative pain at baseline and at months 3 and 6 postintervention using a visual analog scale (VAS), (6) lumbar function at baseline and months 3 and 6 postintervention using the Oswestry Disability Index (ODI) and the Japanese Orthopedic Association (JOA) scale, and (7) complications. Results: Compared with the control group, the intervention group's perioperatively related and inflammatory-response indexes were significantly better: (1) amount of bleeding- 112.67 ± 17.38 for the control group and 78.62 ± 10.52 for the intervention group (P = .002); (2) volume of drainage-79.63 ± 14.21 for the control group and 52.18 ± 8.21 for the intervention group (P = .001); (3) ESR at baseline and postintervention-22.41 ± 5.62 and 15.18 ± 5.26, respectively, for the control group and 22.58 ± 5.82 and 10.54 ± 3.18, respectively, for the intervention group, with P = .013 postintervention; and (4) CRP at baseline and postintervention-17.42 ± 3.52 and 13.98 ± 3.65 for the control group, respectively, and 18.65 ± 3.78 and 10.14 ± 2.78 for the intervention group, with P = .008 postintervention; Also, compared to the control group, the intervention group's: (1) total effective rate was significantly higher (P = .018); (2) incidence of postoperative complications was significantly lower (P = .006); (3) VAS pain score was significantly lower at months 3 and 6, with P = .028 and P = .021, respectively; (4) Oswestry Disability Index (ODI) function score was significantly lower at months 3 and 6, with P = .016 and P = .014, respectively; and (5) postoperative JOA function score was significantly higher at months 3 and 6, with P = .011 and P = .007, respectively. Conclusions: Both percutaneous, endoscopic, large-channel fusion and TLIF had good therapeutic effects in the treatment of degenerative lumbar spinal stenosis. However, compared with the latter, the former was more effective, with better comprehensive efficacy and more obvious benefits for patients, so it's worthy of clinical promotion and use.

Comparison of Minimally Invasive Valve Surgery: Hemi-Sternotomy vs. Right Anterolateral Thoracotomy Incision.

Objective: This study aims to compare patient data from two different surgical approaches for minimally invasive valve surgery: hemi-sternotomy and right anterolateral thoracotomy. The primary objective is to determine the safety and efficacy of both surgical incisions. Methods: Between December 2019 and December 2022, a total of 90 patients underwent minimally invasive valve surgery at our center. Among them, 36 patients received the hemi-sternotomy incision with an average age of 45.86 ± 14.83, and 54 patients received the right anterolateral thoracotomy with an average age of 56.77 ± 14.83 years. In the hemi-sternotomy group, 21 patients underwent aortic valve surgery, and 15 had mitral valve surgery, while in the right anterolateral thoracotomy group, 30 patients underwent aortic valve surgery, and 15 patients had mitral valve surgery. Results: No deaths or significant bleeding occurred in the hemi-sternotomy group. However, in the right anterolateral thoracotomy group, one patient died from continuous low cardiac output syndrome after surgery, and one patient suffered a femoral artery dissection. All other patients were discharged without complications. The aortic clamp time and the cardiopulmonary bypass time were significantly lower in the hemi-sternotomy group compared to the right anterolateral thoracotomy group. Conversely, the two groups had no significant differences in intubation time, 24-hour drainage, hospitalization time, and blood transfusion. On the second day after surgery, serum c-TNT and NT-PROBNP levels significantly increased in both groups, but they were significantly higher in the right anterolateral thoracotomy group than in the hemi-sternotomy group. However, on the fifth day after surgery, serum c-TNT and NT-PROBNP levels decreased significantly in both groups, with no significant differences between them. Conclusions: Minimally invasive valve surgery, whether performed with right anterolateral thoracotomy or hemi-sternotomy, is safe and effective after the learning curve. Patients can benefit from these advances in minimally invasive cardiac surgery, and surgeons can easily master these techniques.

Comparison of 270-degree percutaneous transforaminal endoscopic decompression under local anesthesia and minimally invasive transforaminal lumbar interbody fusion in the treatment of geriatric lateral recess stenosis associated with degenerative lumbar spondylolisthesis.

PURPOSE: Various lumbar decompression techniques have been used for the treatment of degenerative lumbar spondylolisthesis (DLS). Few studies have compared the clinical efficacy of percutaneous transforaminal endoscopic decompression (PTED) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) in the treatment of lateral recess stenosis associated with DLS (LRS-DLS) in geriatric patients. The objective of the study was to compare the safety and short-term clinical efficacy of 270-degree PTED under local anesthesia and MIS-TLIF in the treatment of LRS-DLS in Chinese geriatric patients over 60 years old. MATERIALS AND METHODS: From January 2017 to August 2019, the data of 90 consecutive geriatric patients with single-level L4-5 LRS-DLS were retrospectively reviewed, including those in the PTED group (n = 44) and MIS-TLIF group (n = 46). The patients were followed up for at least 1 year. Patient demographics and perioperative outcomes were reviewed before and after surgery. The Oswestry Disability Index (ODI), visual analog scale (VAS) for leg pain, and modified MacNab criteria were used to evaluate the clinical outcomes. X-ray examinations were performed 1 year after surgery to assess the progression of spondylolisthesis in the PTED group and bone fusion in the MIS-TLIF group. RESULTS: The mean patient ages in the PTED and MIS-TLIF groups were 70.3 years and 68.6 years, respectively. Both the PTED and MIS-TLIF groups demonstrated significant improvements in the VAS score for leg pain and ODI score, and no significant differences were found between the groups at any time point (P > 0.05). Although the good-to-excellent rate of the modified MacNab criteria in the PTED group was similar to that in the MIS-TLIF group (90.9% vs. 91.3%, P > 0.05), PTED was advantageous in terms of the operative time, estimated blood loss, incision length, drainage time, drainage volume, length of hospital stay, and complications. CONCLUSIONS: Both PTED and MIS-TLIF led to favorable outcomes in geriatric patients with LRS-DLS. In addition, PTED caused less severe trauma and fewer complications. In terms of perioperative quality-of-life and clinical outcomes, PTED could supplement MIS-TLIF in geriatric patients with LRS-DLS.

[Minimally Invasive Treatment of Benign Prostate Enlargement]. / Minimalinvasive Therapie der gutartigen Prostatavergrösserung.

Minimally Invasive Treatment of Benign Prostate Enlargement Abstract: Minimally invasive techniques are becoming increasingly important treatment options for benign prostate enlargement. With regard to the available evidence, UroLift has a high level of evidence with two prospective randomized studies compared to sham surgery or TUR-P (Transurethral resection of the prostate). The technique is characterized by a significantly higher rate of ejaculation preservation compared to TUR-P, while the improvement in objective voiding parameters is inferior to TUR-P. With regard to Rezum water vapor ablation of the prostate, data from a randomized study compared to sham surgery and several cohort studies are available, which show a significant improvement in urinary symptoms with a high rate of sexual function preservation. The iTIND (temporary implantable nitinol device) procedure has the least amount of evidence, with only one randomized study versus sham surgery with a follow-up of one year. This technique also shows a significant improvement in urinary symptoms with a low rate of comorbidities. Prostatic stents have been on the market for many years, but data from randomized trials are still lacking. When selecting minimally invasive techniques, one should balance the wishes and expectations of the patient with respect to less comorbidities and impact on sexual function against potentially inferior improvement of symptoms and micturition parameters compared to standard techniques.

Minimally Invasive Surgery for the Treatment of Moderate to Critical Acute Pancreatitis: A Case-matched Comparison With the Traditional Open Approach Over 10 years.

PURPOSE: The purpose of this study is to compare short-term and midterm outcomes between patients with acute pancreatitis (AP) treated with minimally invasive surgery (MIS) and patients treated with open necrosectomy (ON). MATERIALS AND METHODS: We compared data of all patients who had undergone MIS for AP with a similar group of patients with ON patients between January 2012 and June 2021 using a case-matched methodology based on AP severity and patient characteristics. Inhospital and midterm follow-up variables, including quality-of-life assessment, were evaluated. RESULTS: Starting from a whole series of 79 patients with moderate to critical AP admitted to our referral center, the final study sample consisted of 24 patients (12 MIS and 12 ON). Postoperative (18.7±10.9 vs. 30.3±21.7 d; P =0.05) and overall hospitalization (56.3±17.4 vs. 76.9±39.4 d; P =0.05) were lower in the MIS group. Moreover, the Short-Form 36 scores in the ON group were statistically significantly lower in role limitations because of emotional problems ( P =0.002) and health changes ( P =0.03) at 3 and 6 months and because of emotional problems ( P =0.05), emotional well-being ( P =0.02), and general health ( P =0.007) at 1 year. CONCLUSIONS: MIS for the surgical management of moderate to critical AP seems to be a good option, as it could provide more chances for a better midterm quality of life compared with ON. Further studies are needed to confirm our findings.

A triple minimally invasive surgery combination for subacute osteoporotic lower lumbar vertebral collapse with neurological compromise: a potential alternative to the vertebral corpectomy/expandable cage strategy.

OBJECTIVE: Acute/subacute osteoporotic vertebral collapses (OVCs) in the lower lumbar spine with neurological compromise, although far less well documented than those in the thoracolumbar junction, may often pose greater treatment challenges. The authors clarified the utility of 3 familiar combined techniques of minimally invasive surgery for this condition as an alternative to the corpectomy/expandable cage strategy. METHODS: This report included the authors' first 5 patients with more than 2 years (range 27-48 months) of follow-up. The patients were between 68 and 91 years of age, and had subacute painful L4 OVC with neurological compromise and preexisting lumbar spinal stenosis. The authors' single-stage minimally invasive surgery combination consisted of the following: step 1, balloon kyphoplasty for the L4 OVC to restore its strength, followed by L4-percutaneous pedicle screw (PPS) placement with patients in the prone position; step 2, tubular lateral lumbar interbody fusion (LLIF) at the adjacent disc space involved with endplate injury, with patients in the lateral position; and step 3, supplemental PPS-rod fixation with patients in the prone position. RESULTS: Estimated blood loss ranged from 20 to 72 mL. Neither balloon kyphoplasty-related nor LLIF-related potentially serious complications occurred. With CT measurements at the 9 LLIF levels, the postoperative increases averaged 3.5 mm in disc height and 3.7 mm in bilateral foraminal heights, which decreased by only 0.2 mm and 0 mm at the latest evaluation despite their low bone mineral densities, with a T-score of -3.8 to -2.6 SD. Canal compromise by fracture retropulsion decreased from 33% to 23% on average. As indicated by MRI measurements, the dural sac progressively enlarged and the ligamentum flavum increasingly shrank over time postoperatively, consistent with functional improvements assessed by the physician-based, patient-centered measures. CONCLUSIONS: The advantages of this method over the corpectomy/expandable cage strategy include the following: 1) better anterior column stability with a segmentally placed cage, which reduces stress concentration at the cage footplate-endplate interface as an important benefit for patients with low bone mineral density; 2) indirect decompression through ligamentotaxis caused by whole-segment spine lengthening with LLIF, pushing back both the retropulsed fragments and the disc bulge anteriorly and unbuckling the ligamentum flavum to diminish its volume posteriorly; and 3) eliminating the need for segmental vessel management and easily bleeding direct decompressions. The authors' recent procedural modification eliminated step 3 by performing loose PPS-rod connections in step 1 and their tight locking after LLIF in step 2, reducing to only once the number of times the patient was repositioned.

Enhancement of gold nanorods-assisted photothermal treatment on cancer with laser power in stepwise modulation.

OBJECTIVES: Photothermal therapy (PTT) is a minimally invasive or noninvasive method by destructing cancer cells through selective thermal decomposition. However, a long period of laser irradiation to achieve coagulative necrosis often causes unfavorable thermal damage to the surrounding healthy tissue. The current study aims to evaluate the feasibility of temporal power modulation to improve the treatment efficacy of gold nanorods-assisted PTT against tumor tissue. MATERIALS AND METHODS: A total of 25 µg/ml of PEGylated gold nanorods (PEG-GNR) was used as an absorbing agent during 1064 nm laser irradiation for PTT. Temperature monitoring was conducted on the aqueous solution of PEG-GNR for dosimetry comparison. For in vivo tests, CT-26 tumor-bearing murine models with PEG-GNR injected were treated with three irradiation conditions: 3 W/cm2 for 90 s, 1.5 W/cm2 for 180 s, and 3 W/cm2 for 60 s followed by 1.5 W/cm2 for 60 s (modulated). Ten days after the treatments, histology analysis was performed to assess the extent of coagulation necrosis in the treated tissues. RESULTS: The temporal power modulation maintained the tissue temperature of around 50°C for a longer period during the irradiation. Histology analysis confirmed that the modulated group entailed a larger coagulative necrosis area with less thermal damage to the peripheral tissue, compared to the other irradiation conditions. CONCLUSION: Therefore, the power-modulated PTT could improve treatment efficacy with reduced injury by maintaining the constant tissue temperature. Further studies will examine the feasibility of the proposed technique in large animal models in terms of acute and chronic tissue responses and treatment margin for clinical translations.

[Minimally Invasive Therapy: What Is The Status In 2021 - What's Coming, What's Going?] / Minimal-invasive Therapie: Wie ist der Stand im Jahre 2021 ­ was kommt, was geht.

Due to the large number of men affected and a variable clinical presentation, the widespread disease "benign prostatic syndrome" requires individual treatment options tailored to the patient's specific clinical characteristics and wishes. If surgical treatment is indicated, there is a wide range of invasive procedures available. For a long time, transurethral resection of the prostate and simple prostatectomy were considered the gold standard, but these procedures are associated with increased morbidity and limitations in sexual function. Therefore, there is now an increasing call for minimally invasive treatment options that will provide effective and safe treatment in the outpatient setting. Over the past years, a variety of technologies and procedures have been developed and tested, but only a few of them have found their way into clinical practice, mostly due to insufficient functional results. For instance, transurethral needle ablation, transurethral microwave thermotherapy, intraprostatic botulinum toxin A or PRX302 injections as well as prostatic stents are no longer recommended. In contrast, the European Association of Urology is currently recommending UroLift, Aquablation and prostatic artery embolisation, which achieve significant long-term improvements in functional parameters while providing a good safety profile and preserved sexual function. Promising data are also available for the temporarily implanted nitinol device (iTIND), Rezum, intraprostatic injection of fexapotide triflutate and transperineal laser ablation of the prostate, but the efficacy and safety of these procedures need to be confirmed in further studies.

Minimal Pilonidal Surgery vs. Common Wide Excision Operations: Better Well-Being and Comparable Recurrence Rates.

BACKGROUND: Pilonidal disease in the natal cleft is treated traditionally by a wide and deep excision of the affected area. There is growing awareness, however, to the advantages of minimally invasive surgeries. OBJECTIVES: To compare the efficacy of wide excision operations and minimal trephine surgery in patients with primary pilonidal disease. METHODS: In this retrospective study we examined surgical and inpatient records of 2039 patients who underwent surgery for primary pilonidal disease in five private hospitals between 2009 and 2012. Most procedures were of lay-open, primary midline closure, and minimal surgery types. Pilonidal recurrence rates were evaluated in a subset of 1260 patients operated by 53 surgeons each performing one type of surgery, regardless of patient characteristics or disease severity. RESULTS: With a mean follow-up of 7.2 years, 81.5%, 85%, and 88% of patients were disease-free after minimally invasive surgery, wide excision with primary closure, and lay-open surgery, respectively, with no statistically significant difference in recurrence rates. Minimal surgeries were usually performed under local anesthesia and involved lower pain levels, less need for analgesics, and shorter hospital stays than wide excision operations, which were normally performed under general anesthesia. The use of drainage, antibiotics, or methylene blue had no effect on recurrence of pilonidal disease. CONCLUSIONS: Minimally invasive surgeries have the advantage of reducing the extent of surgical injury and preserving patient's quality of life. They should be the treatment of choice for primary pilonidal disease.

Online Engagement with Surgical Treatments for Benign Prostatic Hyperplasia: Are Minimally Invasive Surgical Therapies Outpacing the Gold Standard?

Background: Patients suffering from progressive symptoms of benign prostatic hyperplasia (BPH) increasingly turn to the internet for information on invasive and minimally invasive surgical therapies (MIST). This study aimed to identify online articles accessed by patients seeking guidance on said options and to evaluate the quality and readability of their content. Methods: Social media analytics tool Buzzumo was used to identify the most shared articles on Facebook, Twitter, Reddit, and Pinterest related to BPH surgical treatments from 2016 to 2021. The content quality was graded using the DISCERN tool; a questionnaire that assesses the quality of written information on treatment choices for a health problem. An online Automatic Readability Checker was used to evaluate the readability of the written transcripts. Google Trends data were used to evaluate search term popularity for BPH procedures from 2016 to 2021. Google Trends data and DISCERN ratings were analyzed with ANOVA and paired t-test, respectively. Results: Thirty-nine percent of identified articles were rated as low quality, 39% as moderate quality, and 22% as high quality using the DISCERN tool, with no significant difference among reviewer ratings (p = 0.0561). The median reading level of all articles was 12th grade. Google Trends data illustrated a rising popularity of MIST such as Rezum and urethral lift (Urolift), exceeding interest in more invasive procedures such as Holmium laser enucleation of the prostate (HoLEP) and laser surgery. Transurethral resection of the prostate (TURP) remained popular with no significant difference between MIST and TURP on Google Trends (p = 3.46). Conclusions: The most accessed articles on BPH treatments have important shortcomings, including risks of treatment and other available options for treatment. Article transcripts exceed the reading level of the average adult patient. TURP has remained a popular procedure online, but there is a notable rising interest in MIST, especially Urolift.

Adoption of minimally invasive surgery after neoadjuvant chemotherapy in women with metastatic uterine cancer.

OBJECTIVE: Utilization of neoadjuvant chemotherapy (NACT) for advanced stage uterine cancer is increasing. We analyzed the use and outcomes of open versus minimally invasive surgery (MIS) for women with stage IV uterine cancer who received NACT and underwent IDS. METHODS: The National Cancer Database was used to identify women with stage IV uterine cancer diagnosed from 2010 to 2017 and treated with NACT. Among women who underwent IDS, overall survival (OS) was compared between those who underwent laparotomy vs a minimally invasive approach. To account for imbalances in confounders, a propensity score analysis using inverse probability of treatment weighting (IPTW) was performed. RESULTS: A total of 1618 women were identified. Minimally invasive IDS was performed in 31.1% and increased from 16.2% in 2010 to 40.4% in 2017 (P < 0.001). More recent year of diagnosis and performance of surgery at a comprehensive cancer center were associated with increased use of MIS (P < 0.05). Women with serous and clear cell tumors, and carcinosarcomas (compared to endometrioid tumors), as well as Medicaid coverage (compared to commercial insurance) were less likely to undergo an MIS approach (P < 0.05). The median OS was 28 months (95% CI 23.7-30.7) and 24.3 months (95% CI 22.3-26.1) for MIS and laparotomy, respectively. After propensity score balancing, there was no association between the use of MIS and survival (HR = 0.90, 95% CI 0.71-1.14). CONCLUSIONS: Among women with stage IV uterine cancer treated with NACT performance of minimally invasive debulking surgery is increasing. Compared to laparotomy, MIS does not appear to negatively impact survival.

Surgical Treatment for Spasticity: Selective Dorsal Rhizotomy ­ Technique and Literature Review

Spasticity is amotor disorder that leads to a resistance to passive jointmovement. Cerebral palsy is the most important cause of spasticity and can be caused by several factors, including multiple gestations, alcoholism, infections, hemorrhages, drowning, and traumatic brain injuries, among others. There aremany scales that help tomeasure andmonitor the degree of impairment of these patients. The initial treatment should focus on the causal factor, such as tumors, inflammation, degenerative diseases, hydrocephalus, etc. Subsequently, the treatment of spastic musculature includes oral or intrathecal myorelaxants, spinal cord electrostimulation, neurotomies, Lissauer tract lesion, dentatotomy and selective dorsal rhizotomy. The latter is a safetechnique, possibleto beperformed inmost centers with neurosurgical support, and it is effective in the treatment of severe spasticity. In this article, the authors describe the surgical technique and conduct a review the literature.

Ultrasound-guided surgery for lateral snapping hip: a novel ultraminimally invasive surgical technique.

BACKGROUND: Greater trochanteric pain syndrome encompasses a range of causes of lateral hip pain including greater trochanteric bursitis, tendinopathy and tears of the gluteus minimus and medius, and lateral snapping hip (LSH). Surgical options for LSH range from open surgery to endoscopic surgery, including a diamond-shaped cut or a simple transversal release to gluteus maximus tendon release. Resection of an area of proximal iliotibial band (ITB) and step-cut or z-plasty lengthening have not proven superior to transverse release of the ITB. Therefore, making a complete and effective transverse cut guided by ultrasound may represent a potential advance over endoscopic surgery. PURPOSE: In this case series study, we describe how to perform proximal release of the ITB guided by ultrasound. METHODS: The surgical technique-either z-plasty or transverse section of the ITB-was first validated on 10 cadaver specimens and then used in clinical practice. Fourteen patients (5 males and 9 females) were operated from 2014 to 2018. Mean age was 43 years (29-62). RESULTS: The snap resolved in all patients, as verified actively during the surgical procedure as the patient has only local anesthesia. The VAS score for sports activity improved from 7 (5-9) before surgery to 0 (0-2) after 1 year. The HSS score improved from 58 points (47-72) to 96 at 1-2 years. There were no complications other than minor hematomas nor recurrences. CONCLUSION: Ultrasound-guided release of the LSH is a novel surgical option with encouraging results in patients for whom conservative protocols have failed. It can be performed under local anesthesia in an outpatient setting with minimal aggressiveness. It is relatively easy, quick, and painless; no stitches are required. Weight bearing is immediate, and patients usually need crutches for only 2-3 days. Although complete recovery may take 3 months, the rehabilitation protocol is fast and painless.

US-guided percutaneous microwave ablation (MWA) of submandibular gland: A new minimal invasive and effective treatment for refractory sialorrhea and treatment response evaluation with contrast-enhanced imaging techniques.

A 33 years' old male complained of excessive salivation with frequent swallowing and spitting, which resulted in communication disturbance, reduced quality of life, and social embarrassment for 19 years. He had been diagnosed as sialorrhea and submandibular gland hyperfunction by stomatologist, then had unilateral submandibular gland resection 13 years ago, but the symptom relief was not satisfactory. After that, he had been treated with glycopyrrolate for less than a year, which was withdrawn because of the short duration of symptomatic control after each tablet take-in and intolerable side effects. With the wish to receive a new treatment with long term effectiveness, low re-operation risk and normal preserved saliva secretion function, the patient was subject to MWA for the right submandibular gland. After systematic clinical evaluation, US-guided percutaneous MWA was successfully performed with an uneventful post-operative course. The volume of the right submandibular gland and ablated area were measured precisely by an ablation planning software system with automatic volume measurement function based on three-dimensional reconstruction of the pre-operative and post-operative enhanced magnetic resonance imaging (MRI) raw data. Finally, the ablated volume was calculated as 62.2% of the whole right submandibular gland. The patient was discharged 1 day after the operation, with symptoms relieved significantly, the mean value of whole saliva flow rate (SFR) decreased from 11 ml to 7.5 ml per 15 minutes. During the follow up by phone three months after operation, the patient reported that the treatment effect was satisfactory, whereas the SFR value became stable as 7 ml per 15 minutes, drooling frequency and drooling severity (DFDS) score decreased from 6 to 5, drooling impact scale (DIS) score decreased from 43 to 26. US-guided percutaneous MWA of submandibular gland seems to be an alternative, minimal invasive, and effective treatment for refractory sialorrhea.We described a patient with refractory sialorrhea treated successfully with ultrasound (US) guided percutaneous microwave ablation (MWA).

Percutaneous rhinolift procedure for droopy tip.

OBJECTIVE: Droopy tip may lead to functional impairment due to nasal valve insufficiency. There are several techniques available in order to correct under rotated tip, including sutures, resection and grafting. The major drawback of these standart procedures is the correction of nasal cartilage framework rather than droopy skin envelope. In this study, we demonstrated the long-term results of percutaneous rhinolift procedure which aids in the correction of cartilage framework position and droopy skin at the same time, in patients who had isolated nasal tip ptosis. METHODS: Seventeen patients with nasal tip ptosis who underwent rhinolift procedure under local anesthesia, between September 2016 and February 2017, included in the study. Nasal obstruction was evaluated by Nasal Obstruction Symptom Evaluation (NOSE) Scale and Visual Analog Scale (VAS) before the procedure, and 1st month and 3rd month after the procedure. Long-term follow-up scores were also analyzed. RESULTS: There was a significant difference between preoperative NOSE scores and 1st, 3rd month and long-term follow-up scores (p < 0.001). When we analyzed the VAS scores of patients, there was significant difference between preoperative scores and 1st month, 3rd month and long-term follow-up scores (p < 0.001). DISCUSSION: Suspension sutures have been used to hang and lift the ptotic tissues of nasal tip. In this study, we found that rhinolift procedure is an effective method for droopy nasal tip cases especially with excess skin volume who cannot undergo a major invasive surgical operation. IMPLICATIONS FOR PRACTICE: It is a conservative and cheap method which does not require general anesthesia.

Functional Outcome After Minimally Invasive Endoscopic Evacuation of Thalamic Intracerebral Hemorrhage.

BACKGROUND: Intracerebral hemorrhage (ICH) is the most devastating form of stroke, with thalamic hemorrhages carrying the worst outcomes. Minimally invasive (MIS) endoscopic ICH evacuation is a promising new therapy for the condition. However, it remains unclear whether therapy success is location dependent. Here we present long-term functional outcomes after MIS evacuation of spontaneous thalamic hemorrhages. METHODS: Patients presenting to a single urban health system with spontaneous ICH were triaged to a central hospital for management of ICH. Operative criteria for MIS evacuation included hemorrhage volume ≥15 mL, age ≥18, National Institutes of Health Stroke Scale ≥6, and baseline modified Rankin Score (mRS) ≤3. Demographic, radiographic, and clinical data were collected prospectively, and descriptive statistics were performed retrospectively. Functional outcomes were assessed using 6-month mRS scores. RESULTS: Endoscopic ICH evacuation was performed on 21 patients. Eleven patients had hemorrhage confined to the thalamus, whereas 10 patients had hemorrhages in the thalamus and surrounding structures. Eighteen patients (85.7%) had intraventricular extension. The average preoperative volume was 39.8 mL (standard deviation [SD]: 31.5 mL) and postoperative volume was 3.8 mL (SD: 6.1 mL), resulting in an average evacuation rate of 91.4% (SD: 11.1%). One month after hemorrhage, 2 patients (9.5%) had expired and all other patients remained functionally dependent (90.5%). At 6-month follow-up, 4 patients (19.0%) had improved to a favorable outcome (mRS ≤ 3). CONCLUSION: Among patients with ICH undergoing medical management, those with thalamic hemorrhages have especially poor outcomes. This study suggests that MIS evacuation can be safely performed in a thalamic population. It also presents long-term functional outcomes that can aid in planning randomization schemes or subgroup analyses in future MIS evacuation clinical trials.

Rezum therapy for patients with large prostates (≥ 80 g): initial clinical experience and postoperative outcomes.

PURPOSE: Rezum is a minimally invasive surgery for benign prostatic hyperplasia. Current guidelines recommend Rezum for prostates < 80 cc, but little data exist describing outcomes in patients with prostates ≥ 80 cc. We compare outcomes after Rezum between men with small < 80 cc (SP) and large ≥ 80 cc prostates (LP). METHODS: Patients undergoing Rezum between Jan 2017-Feb 2020 were subdivided by prostate volume (< 80, ≥ 80 cc). Outcomes were documented pre- and postoperatively. Descriptive analyses of urodynamics data (Qmax, PVR), symptom scores (AUA-SS, SHIM), disease management (medications, catheterization, retreatments), and clinical outcomes were conducted. RESULTS: 36 (17.6%) men had prostates ≥ 80 cc (LP mean prostate size 106.8 cc). LP men had improved Qmax and PVR postoperatively; those with longitudinal follow-up exhibited improved Qmax, PVR, and AUA-SS. After one year, alpha-blocker usage decreased significantly (LP 94.44-61.11%, p = 0.001, SP 73.96-46.15%, p = 0.001); other medication usage and self-catheterization rates remained unchanged. Compared to SP patients, differences in passing trial void (LP 94.44%, SP 93.45%), postoperative UTI (LP 19.44%, SP 10.12%), ED visits (LP 22.22%, SP 17.86%), readmissions (LP 8.33%, SP 4.76%), and retreatment (LP 8.33%, SP 4.76%) were insignificant. However, mean days to foley removal (LP 9, SP 5.71, p = 0.003) and urosepsis rates (LP 5.56%, SP 0.00%, p = 0.002) differed. CONCLUSION: In select LP patients, Rezum provided short-term symptomatic relief and improved voiding function comparable to SP patients. Postoperatively, though alpha-blocker usage decreased significantly, use of other medications did not change, and nearly two-thirds of patients still needed alpha-blockade. Further efforts should explore the possibility of expanding Rezum's inclusion criteria.

Intra-operative parathyroid hormone evaluation is superior to frozen section analysis in parathyroid surgery.

BACKGROUND: Surgery is currently the only treatment option for patients with primary hyperparathyroidism (PHPT). Recently, minimally invasive parathyroidectomy (MIP) has begun to replace traditional bilateral neck exploration (BNE). OBJECTIVE: The aim of this study is to compare the results of parathyroidectomies performed in our hospital over the past decade that were guided by intra-operative parathyroid hormone (IOPTH) sampling or frozen section (FS) analysis. MATERIAL AND METHODS: Data on 697 patients who underwent parathyroidectomies in the Department of Endocrine Surgery, Dokuz Eylul University between January 2005 and 2018 were included in this study. Patients with malignancies other than thyroid papillary microcarcinoma and parathyroid cancer were excluded from the study. RESULTS: The concomitant use of neck ultrasound (US) and technetium 99m Sestamibi (99mTc MIBI) scintigraphy successfully localized the hyperfunctioning parathyroid glands in nearly 96% of cases. As compared with the IOPTH group, the operation time was longer in the FS group (p < 0.001), and the need for postoperative calcium (Ca) supplementation was higher (p < 0.001). The duration of hospitalization (days) was significantly higher in the FS group (4.2 ± 3.4 vs. 2.6 ± 1.9) as compared with that in the IOPTH group (p < 0.001). In addition, the recurrence rate in the FS group was significantly higher than that in the IPOTH group (p = 0.002). CONCLUSION: IOPTH sampling is a safe and effective method when performed by experienced surgeons and with appropriate preoperative screening. This study emphasizes that IOPTH sampling. We believe that the success in parathyroid surgery is due to three factors: correct indication, accurate localization and experienced surgeon.
