Abstract
Atrial high-rate episodes (AHRE) are atrial tachyarrhythmias that are identified by the use of continuous rhythm monitoring devices such as pacemakers, defibrillators, or implantable cardiac monitors. Nevertheless, the therapeutic implications of these rhythm disturbances remain uncertain. The presence of AHRE is associated with an increased risk of stroke as compared to patients who do not exhibit AHRE. The utilisation of oral anticoagulation has the ability to mitigate the likelihood of stroke occurrence in patients with AHRE. However, it is important to note that this treatment approach is also linked to a severe bleeding rate of approximately 2% per year. The stroke rate among individuals diagnosed with AHRE appears to be comparatively lower when compared to patients diagnosed with atrial fibrillation. The efficacy and safety of anticoagulation in patients with AHRE have yet to be definitively established. Further research is required to provide a comprehensive understanding of the effectiveness and safety of oral anticoagulation in individuals with AHRE.

Abstract
Following heart surgery, postoperative atrial fibrillation (AF) is the most prevalent kind of secondary AF and the most frequent adverse event. Postoperative AF is related to a number of unfavorable cardiac outcomes, such as heart failure, stroke, and death. However, the pharmacological treatment for postoperative AF is only relatively efficient and is frequently linked to detrimental complications, including symptomatic bradycardia with atrioventricular block due to rate control drugs and elevated hemorrhage hazard attributable to the administration of anticoagulants. Ablation procedures also result in the irreversible damage of cardiac anatomic structures, which may have long-term negative implications on heart performance. As a result, there is an unmet demand for treatments that can minimize the incidence of postoperative AF in an effective and safe manner. Botulinum toxin is an established neurotoxin that has progressively gained use in every medical science domain. It hinders the propagation of impulses across nerve fibers without causing immediate damage to the cardiac tissue. The transient feature of botulinum toxin action and the eventual restoration of the autonomic nervous system transmission are undeniably advantageous and may render botulinum toxin a potential and feasible treatment approach for postoperative AF.

Abstract
Interventional electrophysiology represents a relatively recent subspecialty within the field of cardiology. In the past half-century, there has been significant advancement in the development and implementation of innovative ablation treatments and approaches. However, the treatment of arrhythmias continues to be inadequate. Several arrhythmias, such as ventricular tachycardia and atrial fibrillation, pose significant challenges in terms of therapeutic efficacy, whether through interventional procedures or the administration of antiarrhythmic drugs. Cardiologists are engaged in ongoing research to explore innovative methodologies, such as genome editing, with the purpose of effectively managing arrhythmias and meeting the growing needs of patients afflicted with rhythm disturbances. The field of genome editing has significant promise and has the potential to serve as a highly effective personalized therapy for rhythm disorders in patients. However, several ethical issues must be considered.

Abstract
It is well known that thyroid dysfunction increases the risk of cardiovascular mortality and morbidity. The pleiotropic effect of thyroid hormones has a profound effect on the cardiovascular system, influencing both the formation of a normal cardiac rhythm and rhythm disturbance. A number of research studies have demonstrated correlations between TSH and FT4 levels and significant cardiovascular events. The pathophysiological mechanisms underlying these complex associations are, however, inadequately defined. A system-based examination of the relationship between thyroid homeostasis and cardiovascular disease could pave the way for novel study areas and a more individualised strategy for the management of individuals at cardiovascular risk.

Abstract
Background External ventricular drainage (EVD) is one of the most common neurosurgical procedures. Complications are rather rare and mostly include hemorrhage and infection. Hematomas may form during placement or even after the removal of an EVD. Regarding the latter, the literature is scarce, with only nine clinically significant cases reported. Case Description We present the case of a young woman who suffered an extensive hemorrhage after removal of an EVD, in the setting of a posterior fossa stroke. We discuss the management and possible consequences of such an event and we emphasize the need for alertness to avoid such complications. Conclusion Removal of an EVD is a safe procedure, with rare cases of hemorrhagic complications being reported. A case of a large hematoma that formed after the removal of an EVD is presented. Stricter follow-up protocols should be implemented to better estimate the risk of hemorrhage.

Abstract
BACKGROUND/AIM Anastomotic leak (AL) remains one of the most troublesome complications in general surgery. The current review aimed to assess the level of C-reactive protein (CRP) in drainage fluid after entero-enteric, colonic, or colorectal anastomosis as a predictive biomarker for AL. MATERIALS AND METHODS Four medical databases (PUBMED-MEDLINE, Google Scholar, UpToDate, and Cochrane Library) were searched in January 2023 for prospective or retrospective studies on the role of acute-phase proteins in drainage fluid as a predictive biomarker of AL. Two independent researchers gathered and processed the data using MedCalc. The data were pooled and Student's t-test was used to compare the data between the AL and non-AL groups. RESULTS Overall, four studies were included in the current review, containing 753 patients in total, for whom various types of enteric and colonic anastomoses were constructed. Overall 79 (10.49%) of patients demonstrated AL and the mean CRP level (±standard deviation) on postoperative day 3 was 167.7±77.13 mg/l. On the contrary, the non-AL group (674/753) had a statistically significantly lower mean CRP level at 83.76±20.32 mg/l. CRP values were not related to mortality. It was not possible to propose a CRP cut-off indicating an increased risk for AL as the data were insufficient. CONCLUSION The CRP level in drainage fluid might be a valuable biomarker for predicting the possibility of AL in general surgery. However, further and larger-scale studies are needed to establish a CRP cut-off value and this variable would possibly be different for patients with different pathologies.

Abstract
BACKGROUND Since its outbreak in early 2020, the COVID-19 pandemic has diverted resources from non-urgent and elective procedures, leading to diagnosis and treatment delays, with an increased number of neoplasms at advanced stages worldwide. The aims of this study were to quantify the reduction in surgical activity for indeterminate thyroid nodules during the COVID-19 pandemic; and to evaluate whether delays in surgery led to an increased occurrence of aggressive tumours. METHODS In this retrospective, international, cross-sectional study, centres were invited to participate in June 22, 2022; each centre joining the study was asked to provide data from medical records on all surgical thyroidectomies consecutively performed from Jan 1, 2019, to Dec 31, 2021. Patients with indeterminate thyroid nodules were divided into three groups according to when they underwent surgery: from Jan 1, 2019, to Feb 29, 2020 (global prepandemic phase), from March 1, 2020, to May 31, 2021 (pandemic escalation phase), and from June 1 to Dec 31, 2021 (pandemic decrease phase). The main outcomes were, for each phase, the number of surgeries for indeterminate thyroid nodules, and in patients with a postoperative diagnosis of thyroid cancers, the occurrence of tumours larger than 10 mm, extrathyroidal extension, lymph node metastases, vascular invasion, distant metastases, and tumours at high risk of structural disease recurrence. Univariate analysis was used to compare the probability of aggressive thyroid features between the first and third study phases. The study was registered on ClinicalTrials.gov, NCT05178186. FINDINGS Data from 157 centres (n=49 countries) on 87 467 patients who underwent surgery for benign and malignant thyroid disease were collected, of whom 22 974 patients (18 052 [78·6%] female patients and 4922 [21·4%] male patients) received surgery for indeterminate thyroid nodules. We observed a significant reduction in surgery for indeterminate thyroid nodules during the pandemic escalation phase (median monthly surgeries per centre, 1·4 [IQR 0·6-3·4]) compared with the prepandemic phase (2·0 [0·9-3·7]; p<0·0001) and pandemic decrease phase (2·3 [1·0-5·0]; p<0·0001). Compared with the prepandemic phase, in the pandemic decrease phase we observed an increased occurrence of thyroid tumours larger than 10 mm (2554 [69·0%] of 3704 vs 1515 [71·5%] of 2119; OR 1·1 [95% CI 1·0-1·3]; p=0·042), lymph node metastases (343 [9·3%] vs 264 [12·5%]; OR 1·4 [1·2-1·7]; p=0·0001), and tumours at high risk of structural disease recurrence (203 [5·7%] of 3584 vs 155 [7·7%] of 2006; OR 1·4 [1·1-1·7]; p=0·0039). INTERPRETATION Our study suggests that the reduction in surgical activity for indeterminate thyroid nodules during the COVID-19 pandemic period could have led to an increased occurrence of aggressive thyroid tumours. However, other compelling hypotheses, including increased selection of patients with aggressive malignancies during this period, should be considered. We suggest that surgery for indeterminate thyroid nodules should no longer be postponed even in future instances of pandemic escalation. FUNDING None.

Abstract
Robot-assisted surgery is the gold standard of treatment in many fields of urology. In this systematic review, we aim to report its usage in andrology and to evaluate any advantages. A systematic search of the PubMed and Cochrane Library databases was conducted to identify articles referring to robotic-assisted microsurgery in andrology. The search strategy was in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the Cochrane Handbook. The articles were then reviewed by two authors. A qualitative analysis of the articles that met the inclusion criteria was performed. Thirty-one articles that met the inclusion criteria were reviewed. The first results for robot-assisted vasovasostomy (RAVV) are encouraging as excellent patency rates, short operative times, and learning curves were achieved. Interestingly, patency rates were greater in some case series for RAVV than for microsurgical vasovasostomy, with a statistically significant difference. In addition, robot has been shown to be of great use in bypassing fibrotic changes in cases of iatrogenic vasal injuries, difficulties encountered with traditional microsurgery. In addition, the feasibility of robot-assisted microsurgery has been proven for varicocelectomy and microsurgical denervation of the spermatic cord, with acceptable improvement in sperm parameters and pain, respectively. The current evidence suggests that there are potential advantages of the use of robots in andrology. However, for robotic surgery to become incorporated into the daily use of the andrologists, large, multicenter randomized trials are needed. As robotics systems are becoming standard in urology practice, it is reasonable for one to believe that they will also find their place in andrology.

Abstract
Coronary artery disease, autonomic neuropathy, and diabetic cardiomyopathy are the most common cardiovascular complications of diabetes. However, emerging evidence demonstrates that diabetes also affects the heart's electrical conduction system, culminating in lethal arrhythmias and sudden cardiac death. Diabetes and rhythm disturbances have a complex relationship, and arrhythmias cannot be attributed to ischemia and autonomic neuropathy only. Hypoglycemia, hyperglycemia, and glucose fluctuations can potentially induce arrhythmias by activating various pathways. Structural remodeling can accelerate and exacerbate disease development. Mitochondrial dysfunction can also alter the structure and metabolism of cardiomyocytes and contribute to disease progression through oxidative stress and inflammation.

Abstract
PURPOSE Review and efficacy assessment of techniques used for intraprocedural endophytic renal mass localization. MATERIALS AND METHODS Advanced search was carried out on PubMed, Cochrane Library, Web of Science and Google Scholar databases up to August 2020. Eligibility criteria were set, according to PRISMA statement. OR (95 % CI) for identification or technical success, positive margins and recurrence, were calculated for completely endophytic tumors. Risk of Bias was evaluated using ROBVIS tool. RESULTS 77 studies used for result synthesis, including 1,317 endophytic tumors, with 758 of them completely endophytic. 356 endophytic tumors treated laparoscopically and 598 robotically, using ultrasound-based methods, transarterial embolization, dual-source CT, invasive signage, 3D printing, and augmented reality variations. Identification success was 97.8-100%, positive margins 0-12.5 % (completely endophytic: 95 % CI; 0.255-1.971, OR 0.709 in laparoscopic, 95 % CI ; 0.379-3.109, OR 0.086 in robotic partial nephrectomy), recurrences 0-3.9 % (completely endophytic: 0 recurrences in laparoscopic, 95 % CI ; 0.0917-2.25, OR 0.454, in robotic partial nephrectomy), and complications 0-60 % . 363 were treated with ablation techniques using CT-based methods, thermal monitoring, transarterial embolization, ultrasound guidance and invasive signage. Technical success was 33.4-100 % (completely endophytic: 95 % CI ; 0.00157-2.060, OR 0.0569 for invasive and 95 % CI ; 0.598-13.152, OR 2.804 for non-invasive localization techniques) and recurrences were 0-20%. CONCLUSION Ultrasound-based techniques showed acceptable identification success and oncologic outcomes in laparoscopic or robotic setting. Augmented reality, showed no superiority over conventional techniques. Near infrared fluoroscopy with intravenous indocyanine green, was incapable of endophytic tumor tracking, although when administered angiographic, results were promising, along with other embolization techniques. Percutaneous hook-wire or embolization coil signage, aided in safe and successful tracking of parenchymal isoechoic masses, but data are inadequate to assess efficacy. CT-guidance, combined with ultrasound or thermal monitoring, showed increased technical success during thermal ablation, unlike ultrasound guidance that showed poor outcomes.

Abstract
Objective The pursuit of an esthetically pleasing scar following open thyroid surgery has led to the development of endoscopic thyroidectomy through remote incisions placed in several locations outside the neck. The objective of this study is to review the recent literature and compare the incision site appearance and patient satisfaction with the cosmetic outcome after extracervical and conventional thyroidectomy. Methods The English literature published since 2010 was searched through the PubMed/Medline database for studies comparing the cosmetic outcomes between remote-access endoscopic and conventional thyroidectomy using a form of scar assessment scale. Results A total of 9 relevant papers fulfilled the eligibility criteria including 1486 patients. Among them, 595 patients underwent endoscopic thyroidectomy through several remote-access approaches and 891 patients were assigned to the conventional group. Only one randomized-controlled trial was identified, whereas among the rest, four were prospective and four were retrospective nonrandomized cohorts. Regarding the extracervical modifications performed in the endoscopic groups, the axillary approach was performed in three studies and the breast approach in four studies, while the retroauricular facelift technique and the transoral vestibular method were applied in one study, respectively. Conclusions Evaluation of the wound appearance and patient satisfaction with the cosmetic outcome at various time points during the follow-up highlighted the superiority of the extracervical approaches over the conventional cervicotomy. Considering these findings, remote-access techniques could possibly be the ideal surgical method for patients with high esthetic requirements, providing an excellent appearance of the thoroughly exposed neck.

Abstract
BACKGROUND/AIM Laparoscopic colectomy is a procedure which is being performed for three decades and is gaining popularity continuously over the traditional open colectomy. This study was conducted in order to compare postoperative and oncologic results based on several factors in laparoscopic and open right colectomy for right colon cancer. PATIENTS AND METHODS This is a retrospective study of right colectomy at a single institution from 2015 until 2020. The factors that were studied included postoperative values of C-reactive protein (CRP), lactate dehydrogenase (LDH), creatine phosphokinase (CPK), the number of excised lymph nodes, the use of postoperative analgesics and the length of hospital stay. RESULTS We collected data from 21 open and 17 laparoscopic right colectomies through a 5-year period. Measurements on the second postoperative day revealed mean CRP and CPK values significantly lower in the laparoscopic group compared to the open group, while LDH levels did not affirm major differences between the two groups. The mean number of lymph nodes excised during the open procedure was superior to those harvested in the laparoscopic group. The use of analgesics throughout the entire hospital stay was a combination of pethidine and tramadol for the first three postoperative days in open procedures, while paracetamol and, occasionally, tramadol were administered upon patient request following laparoscopic procedures. The mean hospital stay was substantially shorter in the laparoscopic group compared to the open surgery group. CONCLUSION Laparoscopic right colectomy is superior compared to open right colectomy with regards to postoperative analgesia and length of hospital stay, but also in certain postoperative laboratory values. Despite these there was no supremacy considering oncologic clearance.

Abstract
Cardiovascular disease (CVD) remains the leading cause of death worldwide, representing a major health, social, and economic issue. Thyroid disorders are very common and affect >10% of the adult population in total. The aim of this review is to describe the physiologic role of thyroid hormones on cardiovascular system, to present cardiovascular manifestations in patients with thyroid disorders, emphasizing in molecular mechanisms and biochemical pathways, and to summarize current knowledge of treatment options. Thyroid hormone receptors are located both in myocardium and vessels, and changes in their concentrations affect cardiovascular function. Hyperthyroidism or hypothyroidism, both clinical and subclinical, without the indicated therapeutical management, may contribute to the progression of CVD. According to recent studies, even middle changes in thyroid hormones levels increase cardiovascular mortality from 20% to 80%. In more details, thyroid disorders seem to have serious effects on the cardiovascular system via plenty mechanisms, including dyslipidemia, hypertension, systolic and diastolic myocardial dysfunction, as well endothelial dysfunction. On top of clinical thyroid disorders management, current therapeutics focus on younger patients with subclinical hypothyroidism and elderly patients with subclinical hyperthyroidism.

Abstract
BACKGROUND Venous thromboembolism (VTE) is a term used to compositely describe deep vein thrombosis (DVT) and pulmonary embolism (PE). Overall, the incidence of VTE after major abdominal and pelvic surgery has been reported to be between 10% and 40%. OBJECTIVE To estimate the incidence of post-operative VTE in patients undergoing major abdominal surgery for cancer, to identify risk factors associated with VTE, and to assess available thromboprophylaxis tools. METHODS A Medline and Cochrane literature search from database inception until February 1st, 2021 was performed according to the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines. RESULTS Thirty-one studies met our eligibility criteria and were included in the current review. In total, 435,492 patients were identified and the overall incidence of VTE was 2.19%( 95% CI: 1.82-2.38). Τhe following risk factors were associated with VTE: smoking, advanced age (>70 years), a history of diabetes mellitus, American Society of Anesthesiologists' (ASA) classification of Physical Health class III or IV, a history of cardiovascular or pulmonary disease, a history of DVT or PE, elevated plasma fibrinogen level, c-reactive protein (CRP) level, cancer stage III or IV, postoperative acute respiratory distress syndrome (ARDS), prolonged postoperative hospital stay, previous steroid use, history of Inflammatory Bowel Disease (IBD), heart failure and neoadjuvant and adjuvant chemotherapy. CONCLUSION VTE remains an important complication after major abdominal surgery for cancer and seems to increase mortality rates.

Abstract
This review focuses on complications linked to trans-oral endoscopic thyroidectomy via vestibular approach (TOETVA) and aimed to elucidate the procedure's initial safety profile. According to the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA), Pubmed, Embase, and the Cochrane databases were screened till May 2021. Twenty-eight articles, nine cohorts and nineteen case series, met the inclusion criteria. Procedure-related complications were analyzed, the most important being hypoparathyroidism: transient (range=0.94-22.2%), permanent (range=1.33-2.22%), and recurrent laryngeal nerve injury: transient (range=1.9-8.8%) and permanent (range=0.59-1.42%). Surgical trauma related complications, the most prevalent being seroma, emphysema, and hematoma accounted for 2.91%. Null mortality was reported. Although current evolving experience indicates that TOETVA is safe and linked to acceptable complication rates, the method needs to be compared with the gold standard of traditional thyroidectomy in the context of sufficiently numbered cohorts and ultimately randomized controlled trials.

Abstract
OBJECTIVE Trigeminal neuralgia is a long-term facial pain syndrome. Our aim was to review the anatomy of the trigeminal nerve and its anatomical relationship with the adjacent structures that may contribute to the pathogenesis of trigeminal neuralgia METHODS: Eligible articles were identified by a search of the Medline Embase, Pubmed Cinahl and Google Scholar bibliographical databases. We checked all the references of the relevant reviews and eligible articles that our search retrieved, in order to identify potentially eligible conference abstracts. Titles of interest were further reviewed by abstract. Case reports were excluded. RESULTS Trigeminal neuralgia syndrome seems to be caused by anatomical variations of the trigeminal nerve and its adjacent anatomical structures, mainly through compression. We depict the causes, the pathogenesis, and the clinical manifestations of the syndrome. The classification, diagnostic approach, differential diagnosis, and treatment modalities are also presented and they may be personalized according to the anatomical variations of the trigeminal nerve present, which may lead to trigeminal neuralgia syndrome. CONCLUSION It is very important to be very careful in cases of new emerging neuralgia and to avoid the term "idiopathic" until proven otherwise by validating the newer and more appropriate tests and diagnostic criteria. Current data are insufficient and future research is needed in order to discover innovative and more effective treatments of trigeminal neuralgia, considering the anatomy and the anatomical variations of the trigeminal nerve.

Abstract
BACKGROUND/AIM The purpose of this article is to review the published literature on single-port laparoscopic (SPL) ovarian cystectomy and to assess whether the reduced port number affects the ovarian reserve in comparison with the conventional multiport laparoscopic (MPL) ovarian cystectomy. MATERIALS AND METHODS It has been suggested that the most accurate marker of ovarian reserve is the Serum anti-Müllerian hormone (AMH). A review of the current literature was performed based on the preoperative and postoperative AMH after SPL and MPL ovarian cystectomy in adult patients with benign ovarian cysts. RESULTS Ovarian cystectomy causes a non-statistically significant reduction in AMH levels four weeks postoperatively in the SPL group compared to the MPL group [MD = 0.11, 95% CI (-0.01, 0.24), P =0 .07]. Operative time was significantly longer, and blood loss was significantly higher in the SPL group. No difference was reported in terms of major or overall postoperative complications between the two groups. CONCLUSION SPL cystectomy may be offered as a minimally invasive surgical alternative for patients who want to preserve their fertility, at the cost of higher blood loss and longer operative time.

Abstract
OBJECTIVE Atherosclerosis is a chronic inflammatory disease promoted by pro-inflammatory cytokines produced by NOD-, LRR- and pyrin domain-containing protein 3 (NLRP 3) inflammasome. Colchicine is an anti-inflammatory agent that inhibits inflammasome's action and stabilizes atherosclerotic lesions. N-acetylcysteine (NAC) reduces low-density lipoprotein (LDL) oxidation, metalloproteinase levels, and foam cell count and volume. Fenofibrate also has antioxidant, anti-inflammatory, and anticoagulant properties while also having a beneficial effect on the vasomotor function of the endothelium. The purpose of this study is to investigate the effect of per os colchicine administration in combination with fenofibrate and NAC on triglyceride levels and the development of atherosclerotic lesions in cholesterol-fed rabbits. MATERIALS AND METHODS Twenty-eight male, 2 months old New Zealand White rabbits were separated into four groups and were fed with different types of diet for 7 weeks: standard, cholesterol 1% w/w, cholesterol 1% w/w plus colchicine 2 mg/kg body weight plus 250 mg/kg body weight/day fenofibrate, and cholesterol 1% w/w plus colchicine 2 mg/kg body weight plus 15 mg/kg body weight/day NAC. Blood samples were drawn from all animals. Lipid profiles were assessed, and interleukin 6 (IL-6) measurements were performed using an enzyme-linked immunosorbent assay (ELISA) kit. Histologic examination was performed on aorta specimens stained with eosin and hematoxylin. Aortic intimal thickness was evaluated using image analysis. RESULTS Colchicine administration in combination with fenofibrate or NAC statistically significantly reduced the extent of atherosclerotic lesions in aortic preparations. Co-administration of colchicine with NAC has a stronger anti-atherogenic effect than the colchicine plus fenofibrate regimen. Triglerycide levels were decreased in the colchicine plus fenofibrate group and the colchicine plus NAC group at the end of the experiment (p < 0.05), whereas the Cholesterol group had increased levels. A favorable significant lower concentration of IL-6 was detected in the colchicine plus NAC group vs. the other groups. CONCLUSIONS In an experimental rabbit model, it appears that colchicine statistically significantly reduces the development of atherosclerosis of the aorta, especially in combination with NAC. Colchicine, as an NLRP3 inflammasome inhibitor, and NAC, as an agent that directly targets IL-6 signaling, can reduce the inflammatory risk. Fenofibrate enhances the attenuating role of colchicine on triglyceride levels. Clinical studies should investigate whether similar effects can be observed in humans.

Oncol Lett 2021; 22:734. [PMID: 34429774 DOI: 10.3892/ol.2021.12995] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Accepted: 07/26/2021] [Indexed: 01/29/2023] Open
Abstract
Although the use of laparoscopic surgery is increasing, controversy still surrounds its application for malignant conditions. Gastrointestinal stromal tumours (GISTs) are less demanding in terms of lymphadenectomy, meaning that laparoscopic resection might have a more defined benefit when compared with open resection. To the best of our knowledge, no randomized study exists that compares the laparoscopic and open resection of GISTs. The current study aimed to examine the relevant literature by means of a systematic review. A systematic literature search was performed individually by two authors, in which three independent databases were searched using specific search-terms. Titles, abstracts and full texts were screened, as well as references to relevant articles, in order to comprise a comprehensive list of studies. Data were extracted using a detailed pre-agreed spreadsheet. Studies were evaluated according to the modified MINORS criteria. A total of 10 studies were included in the present review, yielding a total of 14 entries. The majority of studies reported significantly improved perioperative outcomes for the laparoscopic approach, including improved duration of operation, blood loss and length of hospital stay. Only four studies reported long-term outcomes and findings that were controversial, with some studies detecting no statistically significant differences, one reporting improved and one reporting worse disease-free and overall survival for the laparoscopic group. Three studies were deemed to be good quality, two of which had not reported significantly different long-term outcomes, while the third had reported significantly improved outcomes in the open resection group. While there is a clear benefit for performing laparoscopic surgery in patients with GIST with regards to perioperative outcomes, when it comes to long-term oncological outcomes, uncertainty over its application remains. The lack of randomized trials, as well as the poor reporting of retrospective studies, limits the amount of evidence that is currently available. Laparoscopic surgery for GIST is certainly safe, feasible and likely cost-effective; however, further studies are required to inform on whether this technique is superior to open resection.
