Investigating the Difference in Quality of Life Between Immediate and Delayed Breast Cancer Reconstruction: A Systematic Review.

Background/Aim: Immediate and delayed breast reconstruction remains a controversial topic. Apart from the clinical outcomes that have to be considered, there is a discrepancy of opinions regarding the potential differences in quality of life. It is essential to clarify this issue, in order to contribute to the reconstruction of the decision-making process. The aim of the study was to investigate potential differences in quality of life between immediate and delayed breast reconstruction patients. Materials and Methods: A systematic review of the literature was carried out, searching for case-control studies that have comparatively examined the effects of delayed and immediate reconstruction on quality of life. A literature search was carried out using the Medline, Scopus and Web of Science databases. The quality of the studies was evaluated using the STROBE checklist for case-control studies. Results: Three studies were found showing that immediate reconstruction led to benefits for the quality of life of patients, while one study showed the opposite. A relevant study revealed no statistically significant differences between the two groups, while another study, showed that immediate reconstruction entailed short-term benefits to quality of life. Four of the studies had debatable methodological approaches. Conclusion: The inconsistent study findings cannot lead to any reliable conclusions regarding differences between immediate and delayed reconstruction in quality of life. It is possible that the results vary due to the time point that the comparisons made. Future research to this direction is warranted.

Perioperative nutritional assessment and management of patients undergoing gastrointestinal surgery.

Malnutrition is a major issue in gastrointestinal perioperative situations, as only 40% of malnourished patients are finally treated. This literature review investigates the inconsistencies regarding the diagnostic approach to both preoperative and postoperative patients and the various underlying causes, as well as the efficiency of the various therapeutic regimens. A literature search was conducted until August 2023 in MEDLINE and Scopus. Clinical studies involving perioperative nutritional assessment in adult gastrointestinal surgery patients during the last 10 years were included in the present review. Finally, 19 articles were included in the study. Preoperative nutritional therapy is increasingly recognized as a key component of surgical care. Malnourished patients who are hospitalized and operated on, have significantly worse clinical results. Gastrointestinal postoperative malnutrition coexists with metabolic stress, as patients usually suffer from minor chronic inflammations; therefore, postoperative malnutrition is the result of a combination of the effects of inflammation and a lack of food intake. Postoperative malnutrition leads to prolonged hospitalizations and hospital complications and therefore the need to treat it is essential. There are many recognized tools for detecting malnutrition. However, all tools showed inconsistent results regarding their validity. Per os feeding after surgery, and dietary supplements when necessary, have been recommended. Therefore, it is very important to reduce malnutrition and define clear strategies towards that direction.

Laparoscopic parastomal hernia repair: keyhole, Sugarbaker, sandwich, or hybrid technique with 3D mesh? An updated systematic review and meta-analysis.

PURPOSE: Parastomal hernia is the most common complication after stoma formation with an incidence that approaches 50% at 2 years postoperatively. In the last decade, different approaches of minimally invasive procedures have been proposed for the treatment of parastomal hernia. Nevertheless, the superiority of one technique over the others remains still unclear. Our objective was to update and systematically analyze current state of research concerning the postoperative outcomes of the four most prevalent minimally invasive techniques. METHODS: A systematic literature search of three databases (Medline, Scopus, Google Scholar) was undertaken for articles published from January 2015 to November 2022. Fifteen studies from a previous meta-analysis on the topic were included. RESULTS: Thirty-three studies incorporating 1289 total patients were deemed eligible for inclusion in the final analysis. The keyhole technique was associated with the highest incidence of postoperative complications and recurrences (31.3% and 24.1%, respectively), followed by the Sugarbaker technique (27.6% and 9%, respectively). Operative time was among the lowest in patients operated with the 3D mesh technique, while patients undergoing the keyhole technique experienced the shortest cumulative length of hospital stay (6 days). CONCLUSION: Each technique demonstrates a unique profile of effectiveness offset by the propensity towards developing postoperative complications. While no conclusive evidence on the optimal technique exist to date, newer minimally invasive techniques show promising results, albeit based on limited data. The future of parastomal hernia repair seems to rely on a highly individualized approach, tailored to the distinctive characteristics of both the hernia and the patient.

CRP in Drain Fluid as a Predictive Marker of Anastomotic Leak in Colorectal Surgery: A Systematic Review of the Literature.

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.

Mechanisms and Therapeutic Approaches for Peritoneal Adhesions: A Comprehensive Review.

Peritoneal adhesions are responsible for several and sometimes severe clinical phenotypes remaining a major problem for many patients today. Adhesions are formed within the peritoneal cavity as a result of surgery, inflammation, or injury and can cause a range of clinical symptoms, including abdominal pain, small bowel obstruction, infertility, and other complications. The incidence of peritoneal adhesions remains high as it is estimated that more than 50% of patients who undergo abdominal surgery will develop adhesions. Although advancements in surgical techniques and perioperative management have been developed, the risk of adhesion formation cannot be eliminated, and thus, the development of effective prevention strategies and treatments remains a priority in the field of surgery. In this review, we summarize the cellular and molecular mechanisms involved in the peritoneal adhesions, but also the experimental therapy approaches that have been investigated toward a solution to their possible clinical phenotypes.

The effect of time since reconstruction on breast cancer patients' quality of life, self-esteem, shame, guilt, and pride.

OBJECTIVES: The aim of this study was to investigate the impact of breast reconstruction time (immediate/at a later time) on women's quality of life, self-esteem, feelings of guilt, and shame. In addition, the study aimed to investigate the association between time till reconstruction in women with later reconstruction on these parameters. METHODS: Data collection for the study was conducted from a sample of 150 women with breast cancer who had undergone reconstruction. Breast-Q, Rosenberg Self-Esteem Scale, and State Shame and Guilt Scale questionnaires were used to study the above variables. RESULTS: Immediate reconstruction was associated with higher psychosocial and sexual well-being scores (p = 0.014 and 0.016, respectively). No other quality of life parameters, neither self-esteem, nor feelings of guilt, shame, and pride, were associated with having a mastectomy and reconstruction at the same time or not. Furthermore, for women who did not have immediate reconstruction, the time elapsed until reconstruction was not associated with quality of life, self-esteem, feelings of guilt, shame, and pride. SIGNIFICANCE OF RESULTS: This study highlights the importance of simultaneous mastectomy and breast reconstruction, as it is associated with higher psychosocial and sexual quality of life. Therefore, simultaneous breast reconstruction is imperative to be provided by health systems.

Comparison of cosmetic outcomes between remote-access and conventional thyroidectomy: A review of the current literature.

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.

Robotic-assisted microsurgery in andrology: a systematic review.

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.

Short-Term Outcomes After Robotic Versus Open Liver Resection: A Systematic Review and Meta-analysis.

BACKGROUND: Robotic liver surgery is a novel technique expanding the field of minimally invasive approaches. An increasing number of studies assess the outcomes of robotic liver resections (RLR). The aim of our meta-analysis is to provide an up-to-date comparison of RLR versus open liver resections (OLR), evaluating its safety and efficacy. MATERIALS AND METHODS: A systematic search of MEDLINE, Scopus, Google Scholar, Cochrane, and Clinicaltrials.gov for articles published from January 2000 until January 2022 was undertaken. RESULTS: Thirteen non-randomized retrospective and one prospective clinical study enlisting 1801 patients met our inclusion criteria, with 640 patients undergoing RLR and 1161 undergoing OLR. RLR resulted in significantly lower overall morbidity (p < 0.001), shorter length of hospital stay (p = 0.002), and less intraoperative blood loss (p < 0.001). Operative time was found to be significantly higher in the RLR group (p < 0.001). Blood transfusion requirements, R0 resection, and mortality rates presented no difference among the two groups. The cumulative rate of conversion was 5% in the RLR group. CONCLUSION: The increasing experience in the implementation of the robot will undoubtedly generate more prospective randomized studies, necessary to assess its potential superiority over the traditional open approach, in a variety of hepatic lesions.

Platelet-rich Plasma Gel versus Hyaluronic Acid on Prevention of Peritoneal Abdominal Adhesion Formation in Rats.

Background: Intra-abdominal adhesion formation is still unavoidable and a cause of significant morbidity in abdominal surgery. Platelet-rich plasma gel and hyaluronic acid have been studied for their protective of therapeutic effects on adhesions. The aim of the present study is to compare Platelet-rich plasma and hyaluronic acid in adhesion prevention. Material and method: Twenty-seven Sprague-Dawley rats were randomly allocated into three equal groups(n=9). Surgical trauma was used to induce adhesion formation. After trauma, 1 ml normal saline was instilled in the peritoneal cavity in control group (n=9), 1 ml liquid Hyaluronic acid (25 mg/ml) was instilled in group A (n= 9) and 1 ml of platelet-rich plasma was instilled in group B (n = 9). Four weeks after the laparotomy, a repetitive laparotomy was performed and adhesions were examined microscopically and macroscopically. Results: Platelet-rich plasma gel and hyaluronic acid both reduce the extent and grade of adhesions macroscopically. Interestingly, PRP turns out to be superior in the reduction of tenacity and adhesion area. Moreover, platelet-rich plasma ameliorates abdominal adhesion formation by reducing neutrophils, fibrosis, and inflammation. Conclusion: The results indicate that platelet-rich plasma gel surpasses hyaluronic acid in abdominal adhesion prevention.

The effect of endometriosis on fertility in an animal model.

The present experimental model aimed to investigate the possible effect of endometriosis on ovarian function by altering follicular maturation and development. This single-blind, randomized study included twenty-four female Sprague Dawley mice, 2.5 months old, weighing 160-200 grams. The animals were randomly separated into four groups on the day of the surgery. Each group consisted of 6 mice. The first group (A) consisted of healthy female mice (control group). The second group (B) consisted of mice subjected to surgical insertion of ovarian endometrioma. The third group (C) consisted of mice subjected to surgically induced diffuse intraperitoneal endometriosis, and the fourth group (D) consisted of mice subjected to surgically induced extraperitoneal endometriosis. According to our experimental model, endometriosis may affect ovarian function by increasing the number of luteinized unruptured follicles (follicles that have undergone luteinization without prior rupture).

Mechanosensitive Stem-Cell Genes and Klotho in Atherosclerotic Aortas: Regulating Spatially Deranged Expression Patterns Using Colchicine Regimens.

AIMS: Inflammatory dysregulation of mechanosensitive developmental genes may be central to atherogenesis. In the present seven-week model, we utilized colchicine regimens to curtail aortic atherogenesis in New Zealand White rabbits. We also explored the effect of colchicine regimens on atheroprotective (Klotho, HOXA5, NOTCH1, and OCT4) and proatherogenic (HIF1a, SOX2, BMP4, and NANOG) genes. METHODS: The control (n = 6) and group A (n = 6) received standard and cholesterol-enriched chow, respectively. Groups B (n = 8) and C (n = 8) were fed hypercholesterolemic diet and were treated with colchicine plus fenofibrate or N-acetylcysteine (NAC), respectively. RESULTS: Group A developed significantly greater thoracic and abdominal aortic atherosclerosis compared to groups B (p < 0.001) and C (p < 0.001). Combining colchicine with NAC resulted in stronger atheroprotection both in the thoracic and the abdominal aorta. In group A thoracic aortas, Klotho was downregulated compared to controls (95% CI: 1.82-15.76). Both colchicine regimens upregulated Klotho back to baseline levels (p < 0.001). Colchicine/fenofibrate also significantly upregulated thoracic NOTCH1 compared to controls (95% CI: -8.09 to -0.48). Colchicine/NAC significantly reduced thoracic NANOG expression compared to hyperlipidemic diet alone (95% CI: 0.37-8.29). In the abdominal aorta, hypercholesterolemic diet resulted in significant downregulation of HOXA5 (95% CI: 0.03-2.74) which was reversed with colchicine/NAC back to baseline (95% CI: -1.19 to 1.51). Colchicine/fenofibrate downregulated HIF1a compared to baseline (95% CI: 0.83-6.44). No significant differences were noted in terms of BMP4, SOX2, and OCT4. CONCLUSIONS: Overall, the aortic expression pattern of mechanosensitive genes seems to be spatially influenced by a hyperlipidemic diet and can be modified using colchicine-based therapy.

Considering "Trifecta" as a Single Outcome when Comparing Robotic With Open Partial Nephrectomy: A Mathematical Model of Volume Conservation and Systematic Review.

BACKGROUND/AIM: Trifecta represents a composite outcome reflecting the quality level of treatment in nephron sparing surgery. However, there is substantial heterogeneity concerning the criteria required for its fulfilment. The present study aimed to highlight the potential of a unified view for the different definitions of trifecta when comparing robotic and open approaches in partial nephrectomy. MATERIALS AND METHODS: A systematic literature search was carried out for all relevant comparative studies published until April 2022. Trifecta definitions were clustered according to two criteria for postoperative renal function reduction. The first set as an upper limit the 10% decrease in the estimated glomerular filtration rate, while the second set as an upper limit 25 min of ischemia. To mathematically investigate the point of intersection between the above two groups, a suitable model of volume conservation equations was formulated. RESULTS: A total of 11 studies were investigated for their methodological features and grouped accordingly. The ischemic zone volume surrounding the tumor resection site emerged as the central parameter connecting the two main definitions. Specifically, for patients with solitary renal masses, a given change in the value of one parameter resulted in a fixed change in the value of the other. CONCLUSION: The two main definitions of the "trifecta outcome" extracted from the international literature represent the two sides of the same coin. Thus, trifecta achievement rates could be utilized by future studies as aggregate data to yield a quantitative estimate of the comparative effect between robotic and open approaches in partial nephrectomy procedures.

Stem cell genes in atheromatosis: The role of Klotho, HIF1α, OCT4, and BMP4.

During fetal development, shear stress regulates several aspects of vascular development. Alterations in signaling pathways due to disturbed flow in atheroprone regions closely mirror phenomena seen during embryogenesis. This flow-dependent dysregulation of developmental genes appears to promote atherogenesis by mediating inflammatory phenomena, cell cycle progression, apoptosis, cell migration, and oxidative stress. Indeed, several stem cell genes have been implicated in vascular health and atheromatosis. Klotho is key in maintaining endothelial integrity, reducing oxidative stress, and sustaining endothelial nitric oxide production. In atherosclerotic lesions, OCT4 mediates the conversion of vascular smooth muscle cells from contractile to a de-dedifferentiated proliferative phenotype with phagocytic ability. HIF1α drives atherosclerotic plaque progression by promoting intraplaque angiogenesis. BMP4 promotes osteochondrogenic development and arterial calcification. Strategic extracellular matrix changes are also seen during the various phases of atherosclerosis. The aforementioned conceptual framework explains how proatherogenic inflammation develops in response to low shear stress. In the present review, we explored the effect of cardinal atheroprotective (Klotho, OCT4) and proatherogenic (HIF1α, BMP4) genes in mediating proatherogenic inflammation.

A Novel Non-invasive Index of Cardiopulmonary Reserve for the Prediction of Failure of Weaning From Mechanical Ventilation.

PURPOSE: To develop an easy-to-implement prediction index of weaning failure for ICU patients. Materials and methods: We developed a prediction index modifying respiratory exchange ratio (RER), Mod-RER, a parameter measured during the cardiopulmonary exercise test (CPET) based on respiratory quotient. The Mod-RER index is the ratio of partial pressure of CO2 in central venous blood over the difference of partial pressure of O2 in arterial and central venous blood (Mod-RER=PcvCO2/PaO2-PcvO2, where PcvCO2 = partial pressure of CO2 in central venous blood, PaO2 = partial pressure of O2 in arterial blood, and PcvO2 = partial pressure of O2 in central venous blood). We prospectively tested its predictive value, compared to other indices of weaning outcome, in an observational study of difficult-to-wean ICU patients. RESULTS: Mod-RER index increased significantly only in failed trials and receiver operating characteristic (ROC) analysis for prediction of outcome based on Mod-RER index change had an area under the curve (AUC) 0.80 (p<0.001). Mod-RER change exhibited the highest sensitivity (84.6%) and specificity (78.1%) among the tested indices, with the optimal cut-off of 19.3%. Comparison of AUCs did not reach statistical significance (p=0.106). CONCLUSIONS: We conclude that Mod-RER index is an accurate, easy-to-use prediction tool of weaning failure, useful in decision making of timely extubation of ICU patients, especially in the demanding era of the coronavirus disease 2019 (COVID-19) pandemic.

The interplay between endometriosis and fertility in rats: a systematic review.

For the last decades, endometriosis has been a major gynecological problem and a significant cause of infertility for women worldwide. It is estimated that the disease affects about 10-15% of all women of reproductive age and 70% of women suffering from chronic pelvic pain. At the same time, the incidence is about 40-60% in women with dysmenorrhea and 20-30% in women with subfertility. Despite the high percentage of affected women, endometriosis is still characterized by insufficient knowledge of the pathogenic processes, leading to the development and continuity of the disease. For this reason, there is a significant need for insight and understanding of the pathogenesis of endometriosis. This systematic review aims to present the latest data on the use of rats in endometriosis research and to explore how fertility is affected in rats with endometriosis. The methodology included a review of the available publications retrieved by a search in various scientific databases, such as PubMed, Scopus, Medline, and Google Scholar. The initial search generated 30 titles, with 10 articles fulfilling the inclusion criteria. In conclusion, several surgical techniques have been proposed to induce endometriosis, mainly using rats as the appropriate animal model. Studies in rats showed that endometriosis causes infertility and that pregnancy rates are lower for rats with endometriosis than those without endometriosis. In addition, rats with endometriosis have significant abnormalities in the structure of their oocytes as well as in the development of their embryos (genetic abnormalities).

Endometriosis and Subfertility: A Literature Review.

Introduction: Endometriosis is a condition that mainly concerns women of reproductive age, which causes several problems, including subfertility. The phenotypic presentation of endometriosis is defined by a complex interplay between genetic profile, immunological and mechanical factors. In this literature review we examine the causality between endometriosis and subfertility, outlining possible mechanisms involved in the pathogenesis. Aim: The purpose of this study was to conduct a literature review in order to identify the correlation between endometriosis and subfertility through possible mechanisms involved in the pathogenesis of endometriosis-associated subfertility and treatment. Methods:A search in Medline/PubMed was done, using the terms "endometriosis" and "subfertility", to identify the most relevant studies that were published during the last six years. Results:Pathogenesis of endometriosis-associated subfertility is not clear yet, although some data indicate that there are several factors that could affect a patient's fertility. Involved mechanisms include mechanical obstruction such as ovarian tubal dysfunction and the abnormal peritoneal microenvironment, genetic, and epigenetic mechanisms, and immunological traits. It is fundamental to better understand these mechanisms in order to improve the therapeutic approach. Conclusions:The clinical management of endometiosis-related subfertility has to be improved. It is important to consider a change in the classification of endometriosis and, more importantly, an effort to avoid surgical procedures. There is a crucial need for effective protocols and novel targets for specific diagnosis and treatment. Consequently, the importance of understanding pathogenesis and genetic mechanisms is underlined. Future researchers should focus on novel non-invasive treatment methods that target specific pathogenic pathways.

Record and Appraisal of Endophytic Tumor Localization Techniques in Minimally Invasive Kidney-Sparing Procedures. A Systematic Review.

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.

Role and Efficacy of Robotic-assisted Radical Antegrade Modular Pancreatosplenectomy (RAMPS) in Left-sided Pancreatic Cancer.

Distal pancreatectomy with splenectomy is the gold-standard surgery for the treatment of left-sided pancreatic cancer. Margin negative resection accompanied by effective lymphadenectomy are the deciding factors affecting the outcome of tail-body pancreatic adenocarcinoma. Radical antegrade modular pancreatosplenectomy (RAMPS) is considered as a reasonable approach for margin-negative and systemic lymph node clearance. Herein, we aim to present all existing data regarding this novel approach including surgical technique and comparison with standardized procedures. RAMPS has shown oncological superiority comparing to distal pancreatectomy with splenectomy due to radical lymphadenectomy and improved dissection of the posterior pancreatic aspects. Robotic-assisted RAMPS has recently been described as a valuable alternative to open RAMPS. With this novel technique, anterior, posterior or modified approaches can be achieved; favorable clinical and oncological outcomes have been reported in the current literature, with reduced conversion rates compared to other minimally invasive approaches, as well as vastly improved maneuverability, accuracy and vision. Robotic-assisted RAMPS is not only technically feasible but also oncologically safe in cases of well-selected, left-sided pancreatic cancer.
