UNASSIGNED: The Da Vinci Surgical System (DVSS) has the advantages of minimal invasion, rapid recovery, safety, and reliability. Although the DVSS has been widely used in various abdominal surgeries, descriptions of its use in robot-assisted retroperitoneal tumor resection (RRTR) are limited to case reports; large-sample systematic studies are lacking. The present study was performed to analyze the data of RRTR in our center, summarize our experience, and provide a reference for other retroperitoneal tumor centers.
UNASSIGNED: We retrospectively analyzed the clinical data of 105 patients who underwent RRTR at the Affiliated Hospital of Qingdao University from January 2015 to December 2022. Logistic univariate and multivariate analyses were performed to identify independent risk factors affecting RRTR. A receiver operating characteristic curve was used to find the cut-off value, which was then included in the logistic multivariate analysis for verification.
UNASSIGNED: Among the 105 patients, 87 successfully underwent RRTR (DVSS group) and 18 underwent conversion to open surgery (conversion group). There was no significant difference in sex, age, body mass index, history of abdominal surgery, or tumor location between the two groups (P > 0.05). The maximum tumor diameter [odds ratio (OR), 1.041; 95% confidence interval (CI), 1.015-1.067; P = 0.002] and pathological property (OR, 8.646; 95% CI, 2.370-31.544; P = 0.001) were independent risk factors for conversion to open surgery. Further analysis confirmed that the success rate of RRTR was higher for tumors with a maximum diameter of ≤64 mm and benign tumors. Based on our experience and statistical results, we believe that retroperitoneal tumors that meet the following criteria have a higher success rate of DVSS resection: maximum tumor diameter of ≤64 mm, benign tumors, the tumor has relatively clear boundary, no obvious invasion of surrounding tissues and organs, and no need for combined organ resection.
UNASSIGNED: RRTR is safe and effective in the treatment of RPT, and the clinical prognosis is similar to that of open surgery. The success rate of RRTR in patients with appropriate surgical indications for this procedure is higher.

UNASSIGNED: As the demand for kidney transplants continues to increase globally, healthcare institutions face a challenge to bridge the gap between patients waitlisted for kidney transplants and the number of donors. A major factor influencing the donor\'s decision is the operative risk and potential complications of the surgery. Open surgical approaches have been vastly replaced with laparoscopic donor nephrectomies as the standard of practice. However, there is a growing body of evidence pointing towards its potential superiority over laparoscopic methods. In this study, we aim to present our experience on outcomes of Robotic-Assisted Live Donor Nephrectomies (RALDN), the first series of its kind in the United Arab Emirates (UAE).
UNASSIGNED: We retrospectively collected data from patients who underwent RALDN at Mediclinc City Hospital. Demographic data, laboratory investigations, and operative details were collected and analyzed.
UNASSIGNED: Seven patients underwent RALDN between 2021 and April 2022 at our facility. Four donors were male while three were female. Median length of hospital stay was 4 days. In our study, one of the patients suffered from a Clavien-Dindo grade IV complication which necessitated prolonged admission.
UNASSIGNED: We conclude that RALDN is a safe method for donor kidney procurement, carrying a low risk of morbidity and mortality. This method could potentially evolve the number of kidney donors to address the issue of high kidney transplant demand.

UNASSIGNED: Accelerated orthodontic treatment has gained popularity in recent years as patients seek shorter treatment durations. Microosteoperforations (MOPs) have emerged as a minimally invasive technique to expedite tooth movement. This study aims to compare the effectiveness of MOPs in accelerating orthodontic treatment with conventional methods.
UNASSIGNED: A randomized controlled trial was conducted on 60 orthodontic patients requiring dental alignment. The participants were divided into two groups: Group A (MOPs) and Group B (conventional orthodontic treatment). In Group A, MOPs were performed at the beginning of the treatment. Both groups received monthly orthodontic adjustments. Treatment duration, rate of tooth movement, and patient discomfort were measured and compared between the two groups.
UNASSIGNED: The study found that in Group A, the treatment duration was reduced by 30% compared to Group B (P < 0.05). The rate of tooth movement in the MOPs group was 1.5 times higher than the conventional group (P < 0.01). Additionally, patient-reported discomfort levels were similar between the two groups. No adverse events related to MOPs were observed during the study.
UNASSIGNED: MOPs significantly accelerate orthodontic treatment, reducing treatment duration by 30% and increasing the rate of tooth movement by 1.5 times compared to conventional methods. Importantly, MOPs are well-tolerated by patients, making them a valuable option for expediting orthodontic treatment with minimal discomfort. This study highlights the potential benefits of integrating MOPs into orthodontic practice to improve treatment efficiency and patient satisfaction.

BACKGROUND: Pilonidal disease (PD) is a common condition for which the global incidence is increasing. Surgery is the currently preferred approach to treatment but there is a growing interest in new minimally invasive techniques, such as sinus laser therapy (SiLaT).
OBJECTIVE: Our primary objective was to assess the efficacy of SiLaT for the treatment of pilonidal disease. The secondary objectives were to evaluate morbidity and patient satisfaction and identify predictive factors of success.
METHODS: All adult patients, who underwent SiLaT in our department for a primary or recurrent pilonidal sinus from June 1, 2018, to December 31, 2020, were included in the study. Healing was defined as the closure of cutaneous orifices and the absence of seepage or abscesses.
RESULTS: In total, 111 consecutive patients, for whom the male/female sex ratio was 2.1 and the mean age 28.8 (± 9.4) years, were included in this study. Eighteen (16.2%) patients had already undergone prior surgery for PD. The mean follow-up was 339.2 (± 221.4) days. A healing rate of 78.4% was observed, with a median time to healing of 20.0 days (15.0-30.0). The median time to return to usual activities was three days (1-7). The only postoperative complication was bleeding, which occurred for two patients (1.8%). Eighty-two patients (88.2%) reported being \"very satisfied\" with the treatment. Multivariate analysis showed no predictive factors for healing among the studied variables.
CONCLUSIONS: SiLaT is an efficient and safe procedure for the treatment of PD, with a high level of patient satisfaction. It will now be necessary to position it within the therapeutic algorithm.

BACKGROUND: Currently, parathyroidectomy is the standard treatment for Primary Hyperparathyroidism (PHPT). Surgical treatment is often effective, although not free of complications and relapses. Minimally invasive techniques, such as Microwave Ablation (MWA) and Radiofrequency Ablation (RFA), are an alternative to surgery in selected patients. We have, herein, reported on the successful use of RFA in a patient with post-surgical persistent hyperparathyroidism.
METHODS: A 54-year-old woman was referred to our Center for mild hypercalcemia with exams revealing Primary Hyperparathyroidism (PHPT). Neck ultrasound and Technetium- 99 Methoxy-isobutyl-isonitrile (99mTc-MIBI) scintigraphy scanning revealed a suspicious right parathyroid hyperplasia/adenoma. She underwent parathyroidectomy and histological examination showed a parathyroid nodular hyperplasia. During the follow-up, she suffered from persistent hyperparathyroidism due to the treatment of left parathyroid hypoplasia with RFA. Blood tests after the procedure showed the remission of the disease 7 months post-treatment.
CONCLUSIONS: A minimally invasive technique for PHPT may represent a valid alternative to surgery, especially in patients with an elevated surgery-related risk. More studies are necessary to investigate the benefit of RFA as a first-line treatment in PHPT.

Currently, there are no standards in surgical treatment of dumbbell-shaped tumors of lumbo-foraminal region.
OBJECTIVE: To evaluate the effectiveness and long-term results of minimally invasive resection of dumbbell-shaped lumbar schwannomas Eden type 2 and 3 combined with transforaminal lumbar interbody fusion and transpedicular stabilization.
METHODS: A retrospective study included 13 patients (8 men and 5 women) with lumbar dumbbell tumors Eden type 2 and 3 who underwent minimally invasive facetectomy through posterolateral anatomical corridor, microsurgical tumor resection and MI TLIF. We analyzed intraoperative parameters, neurological functions (ASIA scale), clinical characteristics (ODI, SF-36), and complications. Resection quality and area of the multifidus muscle were assessed according to MRI data. All patients were followed-up throughout at least 3-year.
RESULTS: Surgery time was 147 min, blood loss - 118 ml, hospital-stay - 7 days. Clinical parameters significantly improved in the follow-up period: ODI score decreased from 72 to 12 (p=0.004), SF-36 PCS increased from 26.24 to 48.51 (p=0.006) and MCS score increased from 29.13 to 53.68 (p=0.002). According to MRI data, no tumor recurrences and severe muscle atrophy (>30%) were observed after 3 years in all cases. Superficial wound infection occurred in 1 (7.7%) case. There were normal neurological functions (ASIA type E) in all patients.
CONCLUSIONS: Minimally invasive facetectomy through posterolateral approach with MI TLIF technology can be used for safe and effective resection of dumbbell-shaped schwannomas Eden type 2 and 3.
В настоящее время отсутствуют стандарты в выборе способа оперативного лечения гантелеообразных опухолей, расположенных в пояснично-фораминальной области.
UNASSIGNED: Оценка эффективности и отдаленных результатов минимально инвазивного удаления гантелеобразных шванном поясничного отдела 2-го и 3-го типов по классификации Eden в сочетании с трансфораминальным поясничным спондилодезом и транспедикулярной стабилизацией (MI TLIF).
UNASSIGNED: В ретроспективное исследование включены 13 пациентов (8 мужчин и 5 женщин) с гантелеобразными опухолями поясничной локализации 2-го и 3-го типов по классификации Eden, которым осуществлялись минимально инвазивная фасетэктомия через заднебоковой анатомический коридор, микрохирургическое удаление опухоли и MI TLIF. Изучались операционные параметры, неврологические функции по шкале ASIA, клинические характеристики (ODI, SF-36), наличие осложнений. По результатам магнитно-резонансной томографии (МРТ) оценивали степень радикальности удаления опухоли и изменения площади многораздельной мышцы. Все пациенты находились под минимальным 3-летним наблюдением.
UNASSIGNED: Средние значения периоперационных данных составили: продолжительность операции 147 мин, объем кровопотери 118 мл, длительность госпитализации 7 дней. В катамнезе установлено значимое улучшение клинических параметров в среднем: функционального состояния по ODI c 72 до 12 (p=0,004), SF-36 PCS с 26,24 до 48,51 (p=0,006) и MCS с 29,13 до 53,68 (p=0,002). По данным МРТ, через 3 года после операции во всех случаях не выявлено рецидивов опухоли, а также выраженной мышечной атрофии (>30%). В 1 (7,7%) случае зарегистрирована поверхностная раневая инфекция. У всех пациентов сохранены нормальные неврологические функции (тип E по шкале ASIA).
UNASSIGNED: Для безопасного, эффективного и радикального удаления гантелеобразных шванном 2-го и 3-го типов по классификации Eden может быть использована минимально инвазивная фасетэктомия из заднебокового доступа с технологией MI TLIF.

Bevezetés: A kéztőalagút-szindróma hazánkban is gyakran előforduló megbetegedés, akár minden 10. embert érintheti. Korai tüneteinek felismerése elengedhetetlen az időben történő diagnózishoz és a beavatkozáshoz. Súlyos vagy konzervatív kezelésekre nem reagáló esetekben sebészeti beavatkozás válhat szükségessé. Célkitűzés: A jelen közlemény célja egy hazánkban újonnan meghonosított, ultrahangvezérelt dekompressziós műtét bemutatása és eredményeinek taglalása. Módszer: A műtét egynapos sebészeti ellátás keretében történik, lokális érzéstelenítésben. Ultrahang segítségével azonosítjuk a medianus ideg lefutását, a fontosabb érképleteket, biztonsági határokat. 2 mm-es bőrmetszésen keresztül folyamatos ultrahangkontroll alatt vezetjük be a műtéti eszközöket. A sarlós szikével alulról metsszük át a ligamentum carpi transversumot, így dekomprimálva a medianus ideget. A teljes dekompressziót igazoljuk ultrahanggal és segédeszközökkel is. A sebet a legtöbb esetben ragasztjuk. Eredmények: A módszert 44 beteg esetében végeztük 2022. október és 2023. november között. A műtétet megelőzően minden esetben ultrahangvizsgálat is történt a szekunder okok és a kontraindikáló tényezők (például egyedi éranatómia) kizárására. Műtéti indikációnak az elektrofiziológiailag igazolt, közepes vagy súlyos fokú idegi károsodást, továbbá a betegek által jelzett, az életminőséget jelentősen rontó, tűrhetetlen panaszokat tekintettük. Intraoperatív vagy major komplikációt egyetlen esetben sem tapasztaltunk. 2 esetben jelentkezett kisebb komplikáció (bőrpír, hosszabb gyógyulás a kéz túl korai erőltetése miatt). A betegek már a műtétet követő 2. naptól a tünetek jelentős csökkenését tapasztalták, és az operált kezüket a mindennapokban használhatták. A zsibbadásos panaszok megszűnése átlagosan 2,5 hét alatt következett be. Következtetés: Az ultrahangvezérelt dekompresszió kiváló és biztonságos lehetőséget nyújt a kéztőalagút-szindróma minimálisan invazív kezelésére. A technika fő előnyei közül kiemelhető az apró vágásból származó kisebb fokú hegesedés, valamint a rövid ideig tartó rehabilitáció és munkába való gyors visszatérés lehetősége.

OBJECTIVE: Single-position surgery with patients in a lateral position, which involves inserting percutaneous pedicular screws (PPS) and lateral interbody fusion (LIF) to avoid changing the position, has been reported. The purpose of the present study was to evaluate the utility and appropriateness of single-position LIF-PPS using O-arm-based navigation in the innovative oblique position.
METHODS: This study involved a retrospective analysis of 92 consecutive patients with lumbar spondylolisthesis who underwent LIF-PPS using O-arm-based navigation. Thirty-five subjects demonstrated surgery with repositioning, as well as 24 in the lateral decubitus position, and 33 in the oblique during PPS, where the position was changed to the lateral decubitus position using bed rotation without resetting. We compared these three groups in terms of the surgery time, blood loss, and the accuracy of the screw placement.
RESULTS: The operative time was significantly shorter in the single-position surgery, both in the lateral and oblique positions, compared to surgery in a dual position. The blood loss was significantly increased in the lateral position compared to the dual and oblique positions. The screw trajectory angle on the downside was significantly smaller in the lateral position, and the accuracy of the screw placement on the downside was significantly lower in the lateral position compared to the dual and oblique positions.
CONCLUSIONS: Single-position surgery could reduce the average surgery time by about 60 min. The present study indicated the oblique position during PPS insertion might make single-position surgery more useful to improve the accuracy of PPS on the downside, with less blood loss.

OBJECTIVE: To comprehensively compare and assess the effects of different lumbar fusion techniques in patients with lumbar spinal stenosis (LSS).
METHODS: PubMed, Embase, Cochrane Library, and Web of Science databases were systematically searched up to December 24, 2022 in this network meta-analysis. Outcomes were pain (pain, low back pain, and leg pain), Japanese Orthopaedic Association (JOA), Oswestry Disability Index (ODI), complications, reoperation, and fusion. Network plots illustrated the direct and indirect comparisons of different fusion techniques for the outcomes. League tables showed the comparisons of any two fusion techniques, based on both direct and indirect evidence. The efficacy of each fusion technique for LSS was ranked by rank probabilities.
RESULTS: Totally 29 studies involving 2,379 patients were eligible. For pain, percutaneous endoscopic transforaminal lumbar interbody fusion (Endo-TLIF) was most likely to be the best technique, followed by minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF), extreme lateral interbody fusion (XLIF), and transforaminal lumbar interbody fusion (TLIF). Percutaneous endoscopic posterior lumbar interbody fusion (Endo-PLIF) had the greatest likelihood to be the optimal technique for low back pain, followed sequentially by MIS-TLIF, minimally invasive posterior lumbar interbody fusion (MIS-PLIF), XLIF, Endo-TLIF, TLIF, oblique lumbar interbody fusion (OLIF), posterior lumbar interbody fusion (PLIF), and posterolateral lumbar fusion (PLF). MIS-PLIF was ranked the most effective technique concerning leg pain, followed by Endo-TLIF, MIS-TLIF, TLIF, Endo-PLIF, PLIF, OLIF, PLF, and XLIF. As regards JOA scores, Endo-TLIF had the maximum probability to be the best technique, followed by MIS-TLIF and TLIF. Endo-PLIF had the greatest likelihood to be the optimum technique for complications, followed by TLIF, MIS-TLIF, Endo-TLIF, OLIF, and XLIF.
CONCLUSIONS: Minimally invasive fusion techniques may be effective in the treatment of LSS, compared with traditional techniques. Minimally invasive techniques were likely non-inferior with regards to postoperative complications.

UNASSIGNED: To assess the effectiveness of a novel minimally invasive Achilles tendon suture instrument in the treatment of fresh closed Achilles tendon rupture.
UNASSIGNED: A retrospective study was conducted on 150 patients who underwent surgical intervention for fresh closed Achilles tendon rupture. Eighty patients were treated with the novel minimally invasive Achilles tendon suture instrument (minimally invasive group) and 70 patients with traditional open surgery (traditional group). The two groups were comparable in terms of gender, age, injured side, cause of injury, the interval between injury and operation, and the distance from the fracture end to the calcaneal tuberosity ( P>0.05). The operation time, intraoperative blood loss, incision length, hospital stays, hospitalization expenses, and complications were recorded and compared. At 1 year after operation, the ankle joint function was evaluated by the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score.
UNASSIGNED: The minimally invasive group demonstrated significantly shorter operation time, smaller incision length, and lower intraoperative blood loss when compared with the traditional group ( P<0.05). However, there was no significant difference in terms of hospital stays and hospitalization expenses between the two groups ( P>0.05). All patients were followed up 12-24 months after operation (mean, 15.5 months). In the traditional group, 6 cases of incision necrosis and 7 cases of Achilles tendon adhesion occurred, while in the minimally invasive group, all incisions healed at first intention and no Achilles tendon adhesion occurred. The differences in the incidences of the two complications between the two groups were significant ( P<0.05). At 1 year after operation, the AOFAS ankle-hindfoot score in the minimally invasive group was superior to that of the traditional group ( P<0.05).
UNASSIGNED: In comparison with traditional open surgery, the use of self-designed novel minimally invasive Achilles tendon suture instrument proves to be an ideal technique for treating fresh closed Achilles tendon ruptures. This approach offers the benefits of smaller incisions, fewer complications, and better postoperative functional recovery, without increasing hospital costs.
UNASSIGNED: 介绍一种新型跟腱微创缝合器械，观察其用于修复新鲜闭合性跟腱断裂的临床疗效。.
UNASSIGNED: 回顾分析2017年9月—2022年5月150例符合选择标准的新鲜闭合性跟腱断裂患者临床资料，其中80例采用新型跟腱微创缝合器械修复跟腱（微创组），70例采用传统切开缝合手术（开放组）。两组患者性别、年龄、损伤侧别、致伤原因、受伤至手术时间及断端与跟骨结节距离等基线资料比较，差异均无统计学意义（ P>0.05）。记录并比较两组患者手术时间、术中出血量、切口长度、住院时间、住院费用及并发症发生情况。术后1年采用美国矫形足踝协会（AOFAS）踝-后足评分评价踝关节功能。.
