Review
BACKGROUND
Achilles tenotomy (AT) forms an important aspect of Ponseti's casting method and is performed in 80-90% of idiopathic clubfoot cases to correct residual hindfoot equinus. Different techniques are described in the literature with no clarity on which method is superior. This review aims to analyse the various techniques described, anaesthesia preferences, and outcomes of AT.
METHODS
We searched PubMed, Embase, Scopus, and Ovid MEDLINE for articles describing idiopathic clubfoot cases undergoing primary AT during Ponseti's casting method. Data were extracted from eligible studies for qualitative and quantitative synthesis. The repeat tenotomy and complication rates were taken as outcome parameters.
RESULTS
Nineteen studies were included for systematic review. A percutaneous AT using a scalpel or needle is adequate in most cases and shows promising results. The out-patient department (OPD) tenotomies under local anaesthesia (LA) and operation room (OR) tenotomies under general anaesthesia (GA) were associated with a repeat tenotomy (RT) rate of 2.5% (95%CI, 0.4-5.4%) and 0.8% (95%CI, 0-1.6%), respectively. The difference between OPD and OR groups was not statistically significant (p = 0.875). The pooled analysis shows a failure/relapse rate of 4.2% (1.9-6.4%, p < 0.001) after AT. OPD and OR tenotomies were associated with a complication rate of 1.6% (95%CI, 0.2-3.0%) and 0.5% (95%CI, 0.1-0.8%), respectively, and the difference was not statistically significant (p = 0.807). Bleeding is the most common complication and is controlled in most cases by applying local pressure.
CONCLUSION
Performing Achilles tenotomy in OPD under LA is safe and cost-effective with similar success rates to those done under GA. With the lack of many comparative and higher-level evidence studies at present, we can't conclude if one technique is better than another.

Meta-Analysis
BACKGROUND
A systematic review and meta-analysis were made of the incidence of recurrences in patients with proliferative verrucous leukoplakia (PVL) subjected to different types of treatment.
METHODS
The study was carried out following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement guidelines. A literature search was made in the Medline (PubMed), EMBASE, and Web of Science databases, together with a manual search, covering the period from 1985 to January 2020, with no language restrictions. Studies were included if they described treatments applied to at least 10 patients with the corresponding outcomes. Methodological quality was evaluated using Jadad scale and Newcastle-Ottawa tool. Global incidence was calculated by random effects meta-analysis using the Comprehensive Meta-analysis version 3.0 software. Publication bias was assessed using funnel plots and the Duval and Tweedie trim and fill method.
RESULTS
Of the 922 identified articles, 12 were found to meet the inclusion criteria. Most of them presented moderate or low risk of bias. A total of 397 patients were analyzed. The mean age was 62.34 years and 248 were women (62.5%). The mean follow-up was 79.3 months. The most frequent treatment was surgical removal with a cold scalpel or laser (339 patients). A total of 232 subjects presented lesion recurrence. The combination of proportions global effect meta-analysis yielded a recurrence rate of 67.2% (95% CI: 48.3-81.8), with the absence of publication bias.
CONCLUSIONS
There is not enough scientific evidence to conclude that any treatment strategy is able to reduce the recurrence in PVL.

Meta-Analysis
Adolescents and Adults Undergoing Temperature-Controlled Surgical Instruments vs Electrocautery in Tonsillectomy: A Systematic Review and Meta-analysis of Randomized Clinical Trials.
IMPORTANCE
Several temperature-controlled surgical instruments (TCSIs) have been used in tonsillectomy. However, to our knowledge, a meta-analysis of the differences between modern TCSIs and electrocautery (EC) has not been conducted.
OBJECTIVE
To compare TCSIs with EC with regard to the intraoperative and postoperative parameters of tonsillectomy.
DATA SOURCES
PubMed (MEDLINE), Embase, and the Cochrane Library were searched independently by 2 authors for relevant articles.
STUDY SELECTION
A literature search identified randomized clinical trials comparing the outcomes of TCSIs vs EC. The search keywords were harmonic scalpel, ultracision, PlasmaBlade, coblation, radiofrequency ablation, and tonsillectomy. Studies of adult and adolescent patients were included.
DATA EXTRACTION AND SYNTHESIS
Data from each study were extracted. A random-effects model was used in the pooled analysis.
MAIN OUTCOMES AND MEASURES
Four outcomes were analyzed: postoperative pain level on days 1, 2, 7, and 14 after surgery; postoperative bleeding; operative time; and intraoperative blood loss.
RESULTS
This meta-analysis included 11 studies with a total of 629 unique patients. (Mean ages ranged from 16 to 55 years.) The studies were further categorized by the methods of comparison. Five articles used between-participant comparisons, and 6 used within-participant comparisons (of the left vs right sides of the participant's body). The pooled results of the studies with between-participant measures showed that postoperative pain scores were lower in the TCSI group on the first day (standardized mean differences [SMD], -0.41 [95% CI, -0.77 to -0.06]) and seventh day (SMD, -0.76 [95% CI, -1.47 to -0.04]). The pooled results of the studies with within-participant measures showed that the postoperative pain scores were lower in the TCSI group on the first day (SMD, -0.37 [95% CI, -0.63 to -0.12]) and second day (SMD, -0.60 [95% CI, -1.10 to -0.10]). The pooled analysis of overall bleeding, major bleeding, minor bleeding, primary bleeding, and secondary bleeding in both the types of studies with between-participant measures and those with within-participant measures showed no significant differences between the TCSI and EC groups. Intraoperative blood loss and operative time were not significantly different between the groups.
CONCLUSIONS AND RELEVANCE
Compared with EC, TCSIs were associated with significantly reduced pain on the first day after tonsillectomy, per this meta-analysis. The rates of overall bleeding, primary bleeding, secondary bleeding, major bleeding, and minor bleeding between TCSIs and EC were comparable. Intraoperative blood loss and operative time also showed no significant intergroup differences. Surgeons may consider using these modern instruments according to personal experiences, preferences, and cost-effectiveness criteria.

BACKGROUND
Ovarian endometriomas, resulting from the invasion of endometriosis into ovarian tissue, can significantly affect ovarian reserve, potentially leading to infertility. When conservative treatments fail, it may further aggravate ovarian reserve decline by invading the ovarian cortex and, in severe cases, result in premature ovarian failure and infertility.
OBJECTIVE
This study aimed to investigate the impact of various hemostasis methods on ovarian reserve function in cases of laparoscopic cystectomy for ovarian endometriomas.
METHODS
We conducted a systematic review and meta-analysis to assess the effects of different hemostasis techniques used during laparoscopic cystectomy for ovarian endometriomas. A comprehensive analysis of relevant literature was performed, focusing on the impact of bipolar electrocoagulation, ultrasonic scalpel, and suture hemostasis on ovarian reserve function. The evaluation criteria included Anti-Müllerian hormone levels and antral follicle counts.
RESULTS
Our analysis revealed significant variations in the impact of hemostasis methods on ovarian reserve function. While all methods aimed to stop bleeding during surgery, the thermal damage to surrounding tissues differed. Bipolar electrocoagulation, ultrasonic scalpel, and suture hemostasis showed varying effects on ovarian reserve, with implications for post-operative fertility.
CONCLUSIONS
The choice of the hemostasis method in laparoscopic cystectomy for ovarian endometriomas has a crucial influence on ovarian reserve function. Our findings emphasize the need to consider the potential consequences of thermal damage when selecting a hemostasis technique. Clinicians should weigh the benefits and risks of each method to protect ovarian reserve function effectively. This study offers valuable insights for guiding clinical practice, ensuring optimal outcomes for patients facing endometrioma-related fertility challenges.

Review
The objective of this study was to describe the histological artifacts caused by high-power laser use compared to cold scalpel surgery in oral soft tissue lesions. Clinical studies that evaluated and compared histological artifacts resulting from the use of high-power lasers and cold scalpels in oral soft tissue lesions biopsies were retrieved from seven databases and four grey literatures, up to July 2022. The risk of bias was investigated using the ROBINS-I tool. The certainty of the evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation approach. Seven studies were eligible for qualitative analysis. Based on the results obtained, those four studies had a low risk of bias, and three studies had an unclear risk of bias. The certainty of the evidence was classified as low. Limited evidence showed that epithelial artifacts such as loss of intraepithelial and subepithelial adhesions, accompanied by pyknotic, fusiform, and/or hyperchromic nuclei, were more common when a high-power laser device was used. Four articles reported that the use of high-power lasers did not interfere with the histopathological diagnosis of oral soft tissue lesions. Due to the heterogeneity of the data, a meta-analysis was not performed. Compared to the use of cold scalpels, histological artifacts, particularly those observed in epithelial tissue, are more common when high-powered lasers are used in oral lesions biopsies. The eligibility criteria and adequate indications of high-power lasers in different oral soft tissue lesion treatments must be respected to avoid tissue artifacts that impair precise histopathological diagnosis.

Review
Internal thoracic arteries (ITAs) are the gold standard conduits for coronary revascularization because of their long-term patency and anti-atherosclerotic properties. Harvesting and preparation of ITAs for revascularization is a technically demanding procedure with multiple challenges. Over the last few decades, various methods and techniques for ITAs harvesting have been introduced by different surgeons and applied in clinical practice with different results. Harvesting of ITAs in pedicled or skeletonized fashion, with electrocautery or harmonic scalpel, with open or intact pleura, with clipping the end or keeping it perfused; papaverine delivery with intraluminal injection, perivascular injection, injecting into endothoracic fascia, and papaverine topical spray are the different techniques introduced by the number of researchers. At the same time, access to the ITAs for harvesting has also been studied. Access and harvesting through median sternotomy, mini anterolateral thoracotomy, thoracoscopic, and robotic-assisted harvesting of ITAs are the different techniques used in clinical practice. However, the single standard method for harvesting and preparation of ITAs has yet to be determined. In this review article, we aimed to discuss and analyze all these techniques of harvesting and preparing ITAs with the help of literature to find the best way for ITAs harvesting and preparation for myocardial revascularization.

Meta-Analysis
BACKGROUND
A meta-analysis was performed to evaluate the effectiveness and safety of ultrasonic osteotomes in spine surgery to standard spinal surgery procedures.
METHODS
Using the search keywords "bone curette", "cutter", "scalpel", "bone shaver", "aspirator", "osteotome", "ultrasonic", "piezosurgery", and "dent " in the databases of PubMed (1966-2021.12), Cochrane Library, Embase (1986-2018.12), Web of Science (1978-2021.12), and China Academic Journals Full-Text Database (CNKI, 1979-2021.12). Two researchers reviewed the literature, extracted and extensively assessed the data, and included information on the study quality. RevMan v5.3.5.0 was used for the meta-analysis.
RESULTS
A total of 10 trials with a total of 911 patients were included. The meta-analysis findings revealed that, when compared to traditional methods, ultrasonic osteotomes could save operation time (OR = -18.83, 95 percent CI (-22.76, -14.99), = 0.03) and reduce intraoperative bleeding (OR = -66.73, 95 percent CI (-75.70, -57.76), = 0.04) and postoperative complications (OR = 0.38, 95 percent CI (0.21, 0.69), = 0.001). There was, however, no significant difference in the hospital stay (OR = -1.34, 95 percent CI (-1.90, -0.77), = 0.23) and symptom improvement rate (OR = 1.03, 95 percent CI (0.73, 1.45), = 0.86).
CONCLUSION
There is evidence that using an ultrasonic osteotome in spine surgery is safe and effective and may minimize intraoperative bleeding and save time. However, there is no significant difference in symptom improvement rate, hospital stay length, or postoperative complications compared to standard surgical equipment. Therefore, more high-quality investigations are needed to corroborate the initial results.

: Energy-based devices are widely used in thyroid surgery in order to achieve optimal hemostasis, while their role in the incidence of hypocalcemia and hypoparathyroidism comprises a topic evaluated in numerous studies.: The aim of this systematic review is to investigate the potential benefit of Ultrasonic Shears and Electrothermal Bipolar (Radiofrequency) System in thyroid surgery regarding the incidence of post-operative hypocalcemia and hypoparathyroidism. A systematic review of the literature in PubMed/Medline and Scopus databases was conducted. Forty-nine studies met the inclusion criteria and were analyzed. A statistically decreased rate of transient hypocalcemia and hypoparathyroidism was reported in 15 studies and 4 studies, respectively, when using energy-based devices. However, 18 and 13 surveys examined transient hypocalcemia and hypoparathyroidism, respectively, and demonstrated no statistical difference between energy-based devices and conventional hemostasis. No difference was observed between the groups concerning permanent hypocalcemia. Out of 13 studies, only 2 showed a significant reduction in the occurrence of permanent hypoparathyroidism in the energy-based device group.: Energy-based devices reduced the rate of transient hypocalcemia and hypoparathyroidism after thyroid surgeries in 42.8% and 23.5% of the included studies, respectively. Further studies are needed to evaluate their impact on permanent post-operative hypocalcemia and hypoparathyroidism.

Meta-Analysis Review
BACKGROUND
Surface modification of flow diverters (FDs) has been explored as a solution for reducing thrombotic risk of these devices, without necessarily using dual antiplatelet therapy (DAPT). If effective, this could pose a promising alternative for treatment of ruptured aneurysms not amenable to other modalities.
METHODS
We performed a comprehensive search of PubMed, MEDLINE, and Embase databases following Preferred Reporting Items for Systematic reviews and Meta-analyzes guidelines. We included articles reporting use of surface-modified FDs for treatment of ruptured aneurysms. Demographics, subarachnoid hemorrhage (SAH) severity, aneurysm characteristics, devices used, periprocedural complications, angiographic outcomes, and mortality were extracted for sample size-based weighted analysis.
RESULTS
Six studies comprising 59 patients with 64 aneurysms were included. Mean patient age was 56.6 ± 6.3 years and 60.6% (95% confidence interval [CI], 46.7-72.9%) were women. The anterior circulation was the location in 60.4% (95%CI, 45.5-73.5%) of aneurysms; 41.8% of the aneurysms were saccular (95%CI, 29.3-55.4%), 16.7% were fusiform (95%CI, 8.3-30.8%), 29.9% were dissecting (95%CI, 12.8-55.4%), 24.4% were blood-blister (95%CI, 15.2-36.7%), and 5.7% were mycotic (95%CI, 2-15.1%). Poor SAH grade was reported in 46.9% (95%CI, 33.3-60.9%). Adjunctive coiling was used in 33.2% (95%CI, 12.4-63.6%). Periprocedural thromboembolic and hemorrhagic complications occurred in 20% (95%CI, 7.1-45.1%) and 8.8% (95%CI, 3.7-19.5%), respectively. Complete occlusion was achieved in 76.4% (95%CI, 58.1-88.3%); no retreatments during follow-up were reported. Overall mortality was 15.1% (95%CI, 7.7-27.6%). There were no differences between single antiplatelet therapy (SAPT) and DAPT regimens with respect to periprocedural thromboembolic complications ( = 0.09), hemorrhagic ( = 0.834) complications, and mortality ( = 0.312).
CONCLUSION
Surface-modified FD treatment of ruptured aneurysms resulted in high rates of thromboembolic complications and acceptable rates of hemorrhagic complications. A considerable proportion of aneurysms were nonsaccular. Rates of complete occlusion were high and retreatment were low. Importantly, no statistically significant difference was found between SAPT and DAPT with respect to complications and mortality.

Meta-Analysis
BACKGROUND
Uterine leiomyomas, also referred to as myomas or fibroids, are benign tumours arising from the smooth muscle cells of the myometrium. They are the most common pelvic tumour in women. The estimated rate of leiomyosarcoma, found during surgery for presumed benign leiomyomas, is about 0.51 per 1000 procedures, or approximately 1 in 2000. Treatment options for symptomatic uterine leiomyomas include medical, surgical, and radiologically-guided interventions. Laparoscopic myomectomy is the gold standard surgical approach for women who want offspring, or otherwise wish to retain their uterus. A limitation of laparoscopy is the inability to remove large specimens from the abdominal cavity through the laparoscope. To overcome this challenge, the morcellation approach was developed, during which larger specimens are broken into smaller pieces in order to remove them from the abdominal cavity via the port site. However, intracorporeal power morcellation may lead to scattering of benign tissues, with the risk of spreading leiomyoma or endometriosis. In cases of unsuspected malignancy, power morcellation can cause unintentional dissemination of malignant cells, and lead to a poorer prognosis by upstaging the occult cancer. A strategy to optimise women's safety is to morcellate the specimens inside a bag. In-bag morcellation may avoid the dissemination of tissue fragments.
OBJECTIVES
To evaluate the effectiveness and safety of protected in-bag extracorporeal manual morcellation during laparoscopic myomectomy compared to intra-abdominal uncontained power morcellation.
SEARCH METHODS
On 1 July 2019, we searched; the Cochrane Gynaecology and Fertility Group Specialized Register of Controlled Trials, CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL, LILACS, PubMed, Google Scholar, and two trials registers. We reviewed the reference lists of all retrieved full-text articles, and contacted experts in the field for additional and ongoing trials.
SELECTION CRITERIA
We included all randomised controlled trials comparing in-bag extracorporeal manual morcellation versus intracorporeal uncontained power morcellation during laparoscopic myomectomy in premenopausal women.
DATA COLLECTION AND ANALYSIS
We followed standard Cochrane methods. Two review authors independently reviewed the eligibility of trials, extracted data, and evaluated the risk of bias. Data were checked for accuracy. The summary measures were reported as risk ratios (RR) or mean differences (MD) with 95% confidence interval (CI). The outcomes of interest were a composite of intraoperative and postoperative complications, operative times, ease of morcellation, length of hospital stay, postoperative pain, conversion to laparotomy, and postoperative diagnosis of leiomyosarcoma. Results for the five main outcomes follow.
MAIN RESULTS
We included two trials, enrolling 176 premenopausal women with fibroids, who underwent laparoscopic myomectomy. The experimental group received in-bag manual morcellation, during which each enucleated myoma was placed into a specimen retrieval bag, and manually morcellated with scalpel or scissors. In the control group, intracorporeal uncontained power morcellation was used to reduce the size of the myomas. No intraoperative complications, including accidental morcellation of the liver, conversion to laparotomy, endoscopic bag disruption, bowel injury, bleeding, accidental injury to any viscus or vessel, were reported in either group in either trial. We found very low-quality evidence of inconclusive results for total operative time (MD 9.93 minutes, 95% CI -1.35 to 21.20; 2 studies, 176 participants; I² = 35%), and ease of morcellation (MD -0.73 points, 95% CI -1.64 to 0.18; 1 study, 104 participants). The morcellation operative time was a little longer for the in-bag manual morcellation group, however the quality of the evidence was very low (MD 2.59 minutes, 95% CI 0.45 to 4.72; 2 studies, 176 participants; I² = 0%). There were no postoperative diagnoses of leiomyosarcoma made in either group in either trial. We are very uncertain of any of these results. We downgraded the quality of the evidence due to indirectness and imprecision, because of limited sites in high-income settings and countries, small sample sizes, wide confidence intervals, and few events.
AUTHORS' CONCLUSIONS
There are limited data on the effectiveness and safety of in-bag morcellation at the time of laparoscopic myomectomy compared to uncontained power morcellation. We were unable to determine the effects of in-bag morcellation on intraoperative complications as no events were reported in either group. We are uncertain if in-bag morcellation improves total operative time or ease of morcellation compared to control. Regarding morcellation operative time, the quality of the evidence was also very low and we cannot be certain of the effect of in-bag morcellation compared to uncontained morcellation. No cases of postoperative diagnosis of leiomyosarcoma occurred in either group. We found only two trials comparing in-bag extracorporeal manual morcellation to intracorporeal uncontained power morcellation at the time of laparoscopic myomectomy. Both trials had morcellation operative time as primary outcome and were not powered for uncommon outcomes such as intraoperative complications, and postoperative diagnosis of leiomyosarcoma. Large, well-planned and executed trials are needed.
