A comparative analysis of different reduced-port laparoscopic surgical procedures after non-curative endoscopic resection for early colorectal cancer.

Surgery serves as a salvage procedure for non-curative resection of early-stage colorectal cancer under endoscopy. A standard method for performing additional surgery after endoscopic submucosal dissection (ESD) for early colorectal cancer has yet to be established. To enhance the understanding of different surgical outcomes by discussing additional treatment strategies following non-complete curative endoscopic resection of early colorectal cancer. This retrospective study included 88 patients who were divided into three groups based on the surgical approach: conventional laparoscopic surgery (CLS), single-incision plus one-port laparoscopic surgery (SILS+1), and three-port laparoscopic surgery combined with natural orifice specimen extraction surgery (three-port NOSES). The study aimed to compare the surgical outcomes, safety, and postoperative recovery among these groups. The SILS+1 and three-port NOSES groups demonstrated comparable safety and efficacy to the CLS group in terms of blood loss, complications, number of lymph node dissections, and length of bowel resection. However, the SILS+1 and three-port NOSES groups had advantages in terms of incision length (7.11 ±0.38, 4.24 ±0.33, 3.16 ±0.22, p < 0.001), postoperative pain (4.000 [3.0,5.0], 3.500 [3.0,4.0], 3.000 [3.0,4.0]; p = 0.003), cosmetic result (4.000 [3.8,5.0], 7.000 [7.0,8.0], 7.000 [7.0,8.0]; p < 0.001), and hospital stay (8.000 [7.0,9.0], 7.000 [6.3,8.0.], 7.000 [6.3,8.0]; p = 0.035). Different strategies of reduced-port laparoscopic surgery have been demonstrated to be effective and safe in additional surgery after non-curative ESD. These techniques have shown reduced pain and increased satisfaction among patients. Reduced-port laparoscopic surgery is expected to become the preferred treatment option for these patients.

"Self-Designed Simulation-Based Laparoscopic Training Program for Urology Residents: Results After 6 Years of Experience".

Learning laparoscopy (LAP) is challenging and requires different skills to conventional open surgery. There is a recognized need for a standardized laparoscopic training framework within urology to overcome these difficulties and to shift learning curve from patient to skills laboratory. Simulation-based training has been widely commented, but implementation in real day practice is lacking. We present our "LAP training program for residents". Between 2017 and 2022, 11 residents participated in our self-designed program: Theoretical: (Moodle platform) basic knowledge and multimedia content for initiation into LAP. Evaluated through online exam. Practical: exercises for LAP skills acquisition were proposed and encouraged residents' practice in a box trainer available and experimental surgery sessions on a porcine model. On-site E-BLUS (European Basic Laparoscopic Urologic Skills) examination was performed annually. Feedback was obtained through an anonymous online survey. All residents positively evaluated the program. Theoretical: 82% passed the online exam. The most valued topics: LAP in special clinical situations, complications, instruments, and configuration of the operating room (OR). Practical: all residents increased dry-lab box practices. A total of 23 experimental surgical sessions were carried out. For 64%, simulation in the experimental OR was a necessary complement to achieve laparoscopic skills and allowed them to feel more confident. Forty-five percent considered it essential to improve their surgical technique. E-BLUS evaluation was valued as a means to achieve dexterity and safer surgery by 90%. Reduction in time and errors were observed through time, although only 2 passed the E-BLUS. Our program for learning LAP includes the acquisition of knowledge, training of basic skills and surgical technique in a safe environment, as well as an objective evaluation. Encouraged practice of basic skills and surgical technique simulation and improved objective evaluation. It is structured, reproducible, systematic and has been positively valued, although it requires commitment for success.

Clinical and Aesthetic Evaluation of Minimally Invasive Surgical Therapy for the Treatment of Gingival Recession Defects - A Systematic Review of Randomized Clinical Trials

Background: The concept of minimally invasive dentistry has seamlessly blended into the various fields of dentistry including periodontics. The past three decades have witnessed a paradigm shift from conventional surgical procedures to microsurgery in the field of periodontal plastic surgery. This entails the integration of microsurgical principles, refined surgical skills and magnification devices along with microsurgical instruments. This systematic review of the randomized clinical trials attempts to address the clinical question whether the application of minimally invasive surgical procedures for gingival augmentation and root coverage procedures for the treatment of gingival recession translate into superior clinical and patient oriented results as compared to conventional root coverage procedures. Materials and Methods: Science Direct and Ovid databases, PubMed, Scopus, and Product literature were accessed to review relevant literature evaluating minimally invasive surgery for treatment of gingival recession defects (GRDs). The search covered 13 studies published in medical and dental journals in English with a relevant impact factor and had a follow up of at least 6 months, up to and including June 2023. The results were based on parameters such as complete root coverage (CRC, expressed as percentage), mean root coverage (MRC, expressed as %) width of keratinized tissue (WKT), and variables such as esthetics and pain postsurgery. Results and Conclusion: The 13 studies pooled in 342 patients who underwent root coverage procedures for treatment of GRDs. The test group (microsurgical) and the control group (macrosurgical group) both resulted in overall improvement in parameters like MRC and CRC, WKT etc. at least 6 months postsurgery; however, statistical difference in between both the groups in these parameters was seen in only three studies. There was marked improvement found in the test group after surgery with respect to esthetics (root coverage aesthetic score) and pain scores (Visual Analog Scale score) as compared to the control group. This compels us to infer that although both conventional and microsurgical procedures are successful as root coverage procedures, microsurgical procedures are minimally invasive and produce superior esthetic and comfort parameters for the patient and are therefore highly recommended in surgical procedures.

Cryostripping Versus Conventional Safenectomy in Chronic Venous Disease Treatment: A Single Center Retrospective Cohort Study.

This study presents a comparative analysis of cryostripping to conventional saphenectomy. Materials and Methods: The study included 2191 patients admitted in the Phlebology Department, 1st Surgical Department, Emergency County Hospital Timisoara, between September 2013 and April 2023, between September 2013 and April 2023, who underwent saphenectomy by cryostripping (1327 patients) or conventionally (864 patients). We compared the duration and costs of the procedure, hospitalization period, post-operative results, method feasibility, as well as the technical advantages of cryostripping compared to conventional surgery. Results: A smaller proximal incision, compared to the classic operation, as well the fact that distal counter incision is not necessary, represents technical advantages of this procedure. Average duration of the intervention was 41 +- 12.8 minutes, consumables costs were about 52 +- 10 EUR/intervention, with an average hospitalization period was 1.05 +- 0.41 days. The post-operative results were favourable, early complications rate being reduced (ecchymoses Phi; 2 cm - 33.23%; hematoma - 2.11%; deep vein thrombosis - 0.15%; transient paresthesias 3.01%). Compared to classic saphenectomy, the costs of consumables/intervention are similar, intervention time, hospitalization period and complication rate being statistically significantly lower. An advantage of the method is the fact that the cryo-probes can be sterilized, being reusable; from the economic point of view, the technique perfectly fits in both public hospitals and private clinics. Conclusions: Cryostripping is a radical surgical procedure which bring a significant number of advantages compared to the classic saphenectomy, being an effective alternative in CVD treatment.

EUS-guided bridging technique for treatment of biliary-enteric anastomotic stenosis after pancreaticoduodenectomy.

Biliary-enteric anastomotic stenosis is one of the main long-term complications after pancreaticoduodenectomy, with an incidence of 2%-8%. Although the relevant reports and studies are relatively few, the consequences such as biliary obstruction and refractory cholangitis seriously affect the quality of life of patients. In this case, the patient is not willing to receive conventional surgery again. This paper provides a bridge technique of EUS-guided Biliary Drainage (EUS-BD) to treat biliary-enteric anastomotic stenosis and solve the problem of obstructive jaundice in the patient.

MISMARPE protocol: minimally invasive surgical and miniscrew-assisted rapid palatal expansion

ABSTRACT Objective: The purpose of this article is to present the MISMARPE technique, a new minimally invasive surgical procedure to treat maxillary transverse atresia in adult patients under local anesthesia and on an outpatient basis. Technique description: The technique consists of miniscrew-assisted rapid palatal expansion (MARPE) associated with a minimally invasive approach using maxillary osteotomies, latency and activation periods until the desired expansion is achieved. The present MISMARPE technique was performed in 25 consecutive cases with a success rate of 96%, yielding good skeletal outcomes with minimal trauma. The expander appliances, with their anchorage types, and a description of the surgical steps of the MISMARPE technique are presented. Conclusion: MISMARPE is a new and effective alternative for less invasive treatment of maxillary transverse deficiency in adults, compared to conventional surgery. Emphasis is placed on the importance of systematic and well-established protocols, for executing the procedures safely and predictably.

Human tracheal transplantation: A systematic review of case reports.

Patients with long-segment airway stenosis not amenable to conventional surgery may benefit from tracheal transplantation. However, this procedure has been only anecdotally reported, and its indications, techniques, and outcomes have not been extensively reviewed. We conducted a systematic Literature search to identify all original articles reporting attempts at tracheal transplantation in humans. Of 699 articles found by the initial search, 11 were included in the systematic review, describing 14 cases of tracheal transplantation. Patients underwent transplantation for benign stenosis in nine cases, and for malignancies in five cases. In 12 cases blood supply to the trachea was provided by wrapping the graft in a vascularized recipient's tissue, while in 2 cases the trachea was directly transplanted as a vascularized composite allograft. The transplantation procedure was aborted before orthotopic transplantation in two patients. Among the remaining 12 patients, there was 1 operative mortality, while 4 patients experienced complications. Immunosuppressants drugs were administered to the majority of patients postoperatively, and only one group of authors attempted their withdrawal, in five patients. At the end of follow-up, all 11 patients surviving the operation were alive, but 2 had a recurrent tracheal stenosis requiring an airway appliance for breathing. Human tracheal transplantation is still at an embryonic phase. Studies available in the Literature report different surgical techniques, and information on long-term outcomes is still limited. Future research is needed in order to understand the clinical value of this procedure.

Botulinum toxin augmented surgery versus conventional surgery in the management of large-angle concomitant esotropia: A randomized clinical trial.

The surgical management of large-angle concomitant esotropia is challenging with high reoperation rates. This study aims to assess the effectiveness and safety of intraoperative botulinum toxin A (BTA) augmentation compared to surgery alone in large angle concomitant esotropia. This is a prospective randomized interventional study. Patients with large angle concomitant esotropia (≥55 prism diopter [PD]) were randomly allocated to either surgery only (Group I) or BTA augmented surgery (Group II). The surgical effect in PD/mm was calculated and compared between the study groups at all follow up intervals. Treatment was considered successful if the patients had orthotropia ± 10 PD at their final examinations. A total of 23 patients were included in the study, 11 in Group I and 12 in group II. The surgical effect was significantly greater in Group II compared to Group I at all follow up durations. The 1-year surgical effect was 32.5% greater in Group II compared to Group I (5.99 ± 0.69 vs. 4.52 ± 0.91 PD/mm, respectively, P = 0.001). The success rate was greater for Group II compared to Group I (75% vs. 63.64%, respectively), but this difference was not statistically significant (P = 0.901). Botulinum toxin augmented surgery is a good alternative to surgery alone in the treatment of large angle concomitant esotropia. BTA injection exerts a significant augmentation effect on medial rectus muscle recessions.

Laser biomodification of the bone bed surface for placement of spiral dental implants: a study based on scanning electron microscopy.

Various rotary and mechanical instruments are used in conventional oral surgery for osteotomies. Despite the implementation of effective cooling systems, it is difficult to prevent thermal damage to the adjacent bone caused by heat generated during the procedure. A smear layer forms on the surface, which can impede the interaction of blood elements with the underlying tissue, resulting in a delayed healing process.

3D-printed antibiotic-loaded bone cement spacers as adjunctive therapy for hip periprosthetic infection after arthroplasty: A clinical assessment

ObjectiveTo explore the effect of 3D-printing technology in assisting the treatment of periprosthetic infection after total hip arthroplasty (THA) by using personalized antibiotic-loaded bone cement (ALBC) spacers. MethodsThe data of 40 patients with postoperative infection after THA were retrospectively analyzed. The patients were divided into 3D printing group (age 47-78 years) and conventional group (age 57-78 years), with 20 cases in each group. In the stage I surgery, the 3D printing group used 3D printed silicone molds to create ALBC spacers, while the conventional group used traditional manual methods. After the infection was controlled, both groups underwent conventional hip revision surgery in the stage II surgery. All patients were evaluated by Harris hip score (HHS) (primary outcome) for hip function. ResultsAll 40 patients had follow-up data, with 3 months after the first stage and 12 months after the second stage. HHS: The intergroup difference was 11.25 points (97.5% confidence interval (CI), 7.92 to 14.58; P <0.01) at 3 months after the first stage, and 9.15 points (97.5% CI, 4.82 to 13.48; P <0.01) at 12 months after the second stage, and the overall difference between the two groups was 9.55 points (97.5% CI, 5.83 to 13.27; P <0.01), which was statistically significant (P<0.05). ConclusionDuring the follow-up period, the hip functional of the 3D printing group were superior to those of the conventional group in the treatment of infections after THA.

Successful pneumovaginoscopic surgery for recurrent abscess of OHVIRA syndrome, preventing further recurrence and subsequent pregnancy

AbstractIntroductionOHVIRA syndrome is a rare congenital anomaly of Müllerian duct development characterized by uterine didelphys, obstructed hemivagina, and ipsilateral renal agenesis. The primary treatment is surgical excision of the obstructed hemivaginal septum and hematometrial drainage. In recent years, minimally invasive approaches such as hysteroscopic or vaginoscopic septum resection have been reported. Furthermore, we originally developed some novel pneumovaginoscopic gynecologic surgeries for years using a device that consists of a cylinder that fits into the vagina and a lid that mounts multiple ports, allowing the vagina to be dilated with carbon dioxide gas, similar to a single‐port laparoscope.Materials and Surgical TechniqueWe report a successful pneumovaginoscopic surgery for a complicated recurrent abscess in a patient with OHVIRA syndrome. Conventional surgery was performed with a single forceps in a liquid, as in cystoscopy or hysteroscopy. However, this new surgery allowed multiple forceps in a gas, as in laparoscopy. So pus and blood were aspirated and washed away without leaking into the abdominal cavity via fallopian tubes. The surgical smoke generated by thermal coagulation also aspirated to clean the field of vision immediately. And thick, complicated abscesses were drained successfully. The patient conceived through IVF with ICSI and delivered safely at full term.DiscussionPneumovaginoscopy could benefit complex vaginal surgery cases, such as abscess formation in patients with OHVIRA syndrome.

On Pump Beating Heart Coronary Artery Surgery in Patients Requiring Urgent Revascularization.

When acute coronary syndrome patients necessitate immediate revascularization, heart-on-pump coronary artery bypass grafting may be regarded as a viable substitute for conventional on-pump surgery. Our clinical experience and initial outcomes of heart-on-pump coronary surgery in patients with acute coronary syndrome are detailed in this article. This research endeavor was a retrospective analysis that spanned the years March 2011 to August 2023. The sample size comprised 2816 patients who had undergone coronary artery surgery. During this period, the same surgical team performed coronary artery bypass surgery on 411 of these patients, who underwent beating heart surgery while on cardiopulmonary bypass support and without cardioplegic arrest; this was done under emergency conditions. 9.3 ± 2.2 hours elapsed between the initiation of acute myocardial infarction and the commencement of coronary artery bypass grafting (CABG). A mean of 4.0 grafts was applied (2.2 ± 1.1). Mortality in hospitals was calculated for sixteen patients. Following surgery, twenty-six patients developed an inadequate cardiac output syndrome. Despite having renal dysfunction, none of the eight individuals needed hemodialysis. The mean duration of stay in intensive care was 3.2 (2.2 ± 1.1) days, while the mean length of hospitalization was 9.2 (4.3 ± 2.4) days. We believe that for high-risk patients with multivascular coronary artery disease who require an emergency coronary artery bypass graft, on-pump beating heart revascularization could be a viable option.

Gastric cancer and mesenchymal stem cell-derived exosomes: from pro-tumorigenic effects to anti-cancer vehicles.

Gastric cancer (GC) is one of the most prevalent malignancies in the world, with a high mortality rate in both women and men. Conventional treatments, like chemotherapy, radiotherapy and surgery, are facing some drawbacks like acquired drug resistance and various side effects, leading to cancer recurrence and increased morbidity; thus, development of novel approaches in targeted therapy would be very beneficial. Exosomes, extracellular vesicles with a size distribution of sub-150nm, interplay in physiological and pathophysiological cell-cell communications and can pave the way for targeted cancer therapy. Accumulating pieces of evidence have indicated that exosomes derived from mesenchymal stem cells (MSC-EXs) can act as a double-edged sword in some cancers. The purpose of this review is to assess the differences between stem cell therapy and exosome therapy. Moreover, our aim is to demonstrate how naïve MSCs transform into GC-MSCs in the tumor microenvironment. Additionally, the tumorigenic and anti-proliferation effects of MSC-EXs derived from different origins were investigated. Finally, we suggest potential modifications and combination options that involve utilizing MSC-EXs from the foreskin and umbilical cord as promising sources to enhance the efficacy of gastric cancer treatment. This approach is presented in contrast to bone marrow cells, which are more heterogeneous, age-related, andare also easily affected by the patient's circulation system.

A comparison of swallowing related quality of life in patients undergoing transoral endoscopic versus open thyroid surgery.

It is important for the endoscopic thyroid surgeon to understand the pros and cons of trans-oral endoscopic thyroidectomy-vestibular approach (TOETVA) vis-à-vis, open conventional thyroidectomy (OTx) so he/she can help patients in making informed choices regarding the type of procedure to opt for. Swallowing related quality of life (SWAL-QoL) has not been compared between the two approaches. Using a rigorous qualitative methodology and validated reliable tool, this study set out to compare the swallowing related quality of life in patients undergoing TOETVA versus OTx. Prospective study at 3 time points in patients planned for hemithyroidectomy (Preoperative, 1week and 12weeks). Data were collected on patients at a tertiary teaching institute in India. Participants ranged from age 18-60years with a diagnosis of benign euthyroid nodule undergoing hemithyroidectomy. Exclusion criteria were-(1) pre-existing vocal cord abnormalities, (2) undergoing surgery for recurrent nodules, and (3) any neuro-muscular disease affecting swallowing ability. Main outcome measure was comparison of swallowing related quality of life domain scores between patients undergoing hemithyroidectomy via either endoscopic trans-oral or open approach. Of the 82 included patients, 40 underwent TOETVA and 42 OTx. Both the groups were comparable in terms of demographic and clinicopathological profile. The mean preoperative SWAL-QOL scores were comparable in all domains. Mean SWAL-QoL scores for all domains on postoperative day 7 were significantly better in TOETVA group with domains burden, eating desire, mental health and communication having medium effect sizes. Physical symptom domain was better in the OTx group but had a small effect size. The difference in SWAL-QoL domains between the two groups persisted for 3months also. Swallowing related quality of life after trans-oral endoscopic thyroidectomy compared to conventional open surgery has not been reported in the literature. Our findings suggest that trans-oral endoscopic thyroidectomy results in significant superior swallowing related quality of life in the majority of domains.

Short-term and long-term efficacy in robot-assisted treatment for mid and low rectal cancer: a systematic review and meta-analysis

ObjectiveThis study aims to conduct a meta-analysis to evaluate the short-term and long-term therapeutic effects of robot-assisted laparoscopic treatment in patients with mid and low rectal cancer.MethodsA comprehensive search strategy was employed to retrieve relevant literature from PubMed, NCBI, Medline, and Springer databases, spanning the database inception until August 2023. The focus of this systematic review was on controlled studies that compared the treatment outcomes of robot-assisted (Rob) and conventional laparoscopy (Lap) in the context of mid and low rectal cancer. Data extraction and literature review were meticulously conducted by two independent researchers (HMW and RKG). The synthesized data underwent rigorous analysis utilizing RevMan 5.4 software, adhering to established methodological standards in systematic reviews. The primary outcomes encompass perioperative outcomes and oncological outcomes. Secondary outcomes include long-term outcomes.ResultA total of 11 studies involving 2239 patients with mid and low rectal cancer were included (3 RCTs and 8 NRCTs); the Rob group consisted of 1111 cases, while the Lap group included 1128 cases. The Rob group exhibited less intraoperative bleeding (MD = −40.01, 95% CI: −57.61 to −22.42, P < 0.00001), a lower conversion rate to open surgery (OR = 0.27, 95% CI: 0.09 to 0.82, P = 0.02), a higher number of harvested lymph nodes (MD = 1.97, 95% CI: 0.77 to 3.18, P = 0.001), and a lower CRM positive rate (OR = 0.46, 95% CI: 0.23 to 0.95, P = 0.04). Additionally, the Rob group had lower postoperative morbidity rate (OR = 0.66, 95% CI: 0.53 to 0.82, P < 0.0001) and a lower occurrence rate of complications with Clavien–Dindo grade ≥ 3 (OR = 0.60, 95% CI: 0.39 to 0.90, P = 0.02). Further subgroup analysis revealed a lower anastomotic leakage rate (OR = 0.66, 95% CI: 0.45 to 0.97, P = 0.04). No significant differences were observed between the two groups in the analysis of operation time (P = 0.42), occurrence rates of protective stoma (P = 0.81), PRM (P = 0.92), and DRM (P = 0.23), time to flatus (P = 0.18), time to liquid diet (P = 0.65), total hospital stay (P = 0.35), 3-year overall survival rate (P = 0.67), and 3-year disease-free survival rate (P = 0.42).ConclusionRobot-assisted laparoscopic treatment for mid and low rectal cancer yields favorable outcomes, demonstrating both efficacy and safety. In comparison to conventional laparoscopy, patients experience reduced intraoperative bleeding and a lower incidence of complications. Notably, the method achieves comparable short-term and long-term treatment results to those of conventional laparoscopic surgery, thus justifying its consideration for widespread clinical application.

Adolescent Idiopathic Scoliosis: Is the Feasible Option of Minimally Invasive Surgery using Posterior Approach?

The purpose of this systematic review and meta-analysis is to perform a systematic review and meta-analysis of previous studies on minimally invasive scoliosis surgery (MISS) in adolescents with idiopathic scoliosis (AIS). Some data on MISS in AIS compared with conventional open scoliosis surgery (COSS) are conflicting. A systematic literature search was conducted in Medline, Embase, and Cochrane Library, including studies reporting outcomes for MISS in AIS. The meta-analysis compared the operative, radiological, and clinical outcomes and complications between MISS and COSS in patients with AIS. Of the 208 records identified, 15 nonrandomized studies with 1,369 patients (reviews and case reports are excluded) were included in this systematic review and meta-analysis. The mean scale was 6.1, and eight of the 15 included studies showed satisfactory quality using the Newcastle-Ottawa scale. For operative outcomes, MISS had significant benefits in terms of estimated blood loss (standard mean difference [SMD], -1.87; 95% confidence interval [CI], -2.94 to -0.91) and hospitalization days (SMD, -2.99; 95% CI, -4.45 to -1.53) compared with COSS. However, COSS showed significantly favorable outcomes for operative times (SMD, 1.71; 95% CI, 0.92-2.51). No significant differences were observed in radiological outcomes, including Cobb's angle of the main curve and thoracic kyphosis. For clinical outcomes, MISS showed significant benefits on the visual analog scale score (SMD, -0.91; 95% CI, -1.36 to -0.47). The overall complication rates of MISS were similar to those of COSS (SMD, 0.96; 95% CI, 0.61-1.52). MISS using the posterior approach provides equivalent radiological and clinical outcomes and complication rates compared with COSS. Considering the lower estimated blood loss, shorter hospitalization days, and longer operative times in MISS, COSS is still the mainstay of surgical treatment in AIS; however, MISS using the posterior approach is also one of the surgical options of choice in the case of moderate AIS.

Ultrasonic Deep-Plane Neck Lift.

Ultrasonic deep-plane neck lift is a new approach for addressing both the subsuperficial musculoaponeurotic system and subplatysmal soft tissues during facial rejuvenation procedures. This innovative surgical approach utilizes 2.2, 2.9, and 3.7 stainless steel probes that are powered by high-frequency ultrasound. Using high-frequency ultrasound in the subcutaneous spaces has been accomplished for the past 20 years with a very suitable safety profile. In this technique, emulsification of the fat layer in both the superficial and deep planes is accomplished with tumescence of the soft tissues in the same fashion as subcutaneous liposuction. In ultrasonic deep-plane neck lift, the superficial and deep layers of fat are targeted for emulsification, and this creates a loosening of these spaces for lifting and repositioning. The procedure facilitates more accurate surgery, because the tissue effects include hemostasis and scalpel- and scissor-free undermining due to the emulsification of the fat layers of the face and neck. The other advantages of ultrasound-assisted facial contouring and rejuvenation include treatment of hard-to-treat areas like the perioral region and distal neck, which can be rapidly and safely undermined utilizing this technology. The third component of ultrasound- and energy-based facial rejuvenation surgery is the long-term remodeling and tightening that occurs beginning approximately 8 weeks after the procedure. When many conventional facelifts are beginning to fall at 3 to 4 months postoperatively, the energy-based facelifts are still tightening and this remodeling continues for up to a year after the procedure. Combining technology with conventional facelift procedures is a new approach to facial rejuvenation and is the result of 15 years of research and cooperation with the aesthetic device industry. The result of this merger of technology with conventional surgery is TESLA Facelifting, the facelift of the future.

UNEXPLAINED UNILATERAL LOWER LIMB NEUROLOGICAL DEFICITS AFTER POSTERIOR SPINAL DECOMPRESSION AND FUSION FOR DEGENERATIVE LUMBAR SPONDYLOLISTHESIS

The observational data from the Spine Patient Outcomes Research Trial (SPORT) confirm the superiority of surgical over conservative management of symptomatic degenerative spondylolisthesis. The most common reported neurologic complications after lumbar posterior decompression and fusion are implant malposition, contralateral foraminal stenosis, hematoma/seroma, arachnoiditis, and nerve root oedema or vascular underlying causes. The current study reported that the patient developed unexpected left side neurological deficit after conventional lumbar posterior spinal decompression surgery for degenerative spondylolisthesis. No intraoperative dural insult. The computer topography (CT) scan and magnetic resonance imaging (MRI) of the spine after index surgery show adequate canal and foraminal decompression. No hardware-related complications or compressive hematoma could explain the patient’s symptoms. The patient recovered completely after removing the redundant posterolateral bone graft. The theory behind that is aggressive posterolateral dissection over the transverse process and abundant application of the bone graft might compress or injure the lumbar plexus. So, we suggested a delicate dissection posterolaterally and only a reasonable amount of bone graft could be applied to prevent such a devastating neurological complication.

Assessing postoperative wound infection rates in ultrasound-guided microwave ablation versus conventional surgery for varicose veins.

Varicose veins are the prevalent vascular disorder that has conventionally been managed via risky postoperative wound infections and conventional surgery. While ultrasound-guided microwave ablation (UMA) has gained attention as a minimally invasive alternative, there is still a lack of research examining its comparative effectiveness. A prospective comparative investigation was undertaken in the Zhejiang region of China from January to November 2023, involving 140 patients who had received the diagnosis of primary varicose veins. An equal number of 70 patients underwent UMA and conventional surgery. Exclusion criteria for the study encompassed adult patients aged 18-65, with the exception of those who had undergone prior venous surgery, deep vein thrombosis or peripheral arterial disease. The demographical characteristics, procedural details and complication profiles of patients who developed postoperative wound infections within 30 days were analysed statistically. The outcomes demonstrated that postoperative wound infections were significantly diminished (5.7%) with UMA in comparison to conventional surgery (17.1%). In addition, the average duration of procedures and length of hospital stay for UMA patients were both reduced, although neither of these differences was found to be statistically significant (p > 0.05). Infection management, age and gender distribution of varicose veins were comparable between the two groups (p > 0.05). A significant inverse correlation was observed between the severity of varicose veins and postoperative outcomes, as determined by the regression analysis (p < 0.05). Using UMA to treat varicose veins showed promise as an alternative to conventional surgery, specifically in minimizing the incidence of postoperative wound infections. Additional research and clinical consideration are needed regarding the potential transition toward minimally invasive techniques in treatment of varicose veins, as suggested by these results.

A comparative study on the clinical efficacy of percutaneous endoscopic lumbar discectomy and conventional open surgery in the treatment of lumbar disc herniation.

To analyze the efficacy of single-channel percutaneous endoscopic lumbar discectomy (PELD) and conventional open surgery in the treatment of lumbar disc herniation (LDH). This is a retrospective study. A total of 66 patients with LDH admitted to Tianjin Medical University from June 2017 to June 2018 were divided into two groups: the observation group (single-channel PELD) and the control group (posterior lumbar interbody fusion), with 33 cases in each group. The two groups were compared in terms of visual analogue scale(VAS), oswestry disability index (ODI), Japanese Orthopaedic Association Score(JOA), perioperative indicators, clinical efficacy, postoperative complications, changes in inflammatory factors and serum T lymphocyte subsets. The operation time, incision length, intraoperative blood loss, time in bed, hospital stay in the observation group were all lower than those in the control group. At 7d after treatment, the improvement of ODI, VAS and JOA in the observation group were better than that in the control group. At the last follow-up, there was no significant difference in Cobb angle and lumbar lordosis angle between the two groups. The levels of serum IL-1, IL-6 and TNF-α in the observation group were lower than those in the control group. The degree of reduction of serum CD3+ and CD4+ in the observation group were higher than those in the control group. And the level of elevation of CD8+ in the observation group was lower than that in the control group. Moreover, there was no significant difference in CD4+/CD8+ level between the two groups. The excellent rate of surgical results in the observation group was higher than that in the control group. Complications occurred in both groups, with no significant difference between the two groups. Single-channel PELD can achieve superior clinical efficacy over conventional open surgery in the treatment of LDH.
