RESUMO
The aim of this study is to compare the diagnostic performance of magnetic resonance imaging (MRI) against computed tomography (CT) in various aspects of local staging in colon cancer patients. This study was a prospective single arm diagnostic accuracy study. All consecutive adult patients with confirmed colon cancer that met the current criteria for surgical resection were considered as eligible. Diagnostic performance assessment included T (T1/T2 vs T3/T4 and < T3ab vs > T3cd) and N (N positive) staging, serosa and retroperitoneal surgical margin (RSM) involvement and extramural vascular invasion (EMVI). Imaging was based on a 3 Tesla MRI system and the evaluation of all sequences (T1, T2 and diffusion-weighted imaging-DWI series) by two independent readers. CT scan was performed in a 128 row multidetector (MD) CT scanner (slice thickness: 1 mm) with intravenous contrast. Pathology report was considered as the gold standard for local staging. Sensitivity (SE), specificity (SP), and area under the curve (AUC) were calculated for both observers. MRI displayed a higher diagnostic performance over CT in terms of T1/T2 vs T3/T4 (SE: 100% vs 83.9%, SP: 96.6% vs 81%, AUC: 0.825 vs 0.983, p < 0.001), N positive (p < 0.001) and EMVI (p = 0.023) assessment. An excellent performance of MRI was noted in the T3ab vs T3cd (CT AUCReader1: 0.636, AUCReader2: 0.55 vs MRI AUCReader1: 0.829 AUCReader2 0.846, p = 0.01) and RSM invasion diagnosis. In contrast to these, MRI did not perform well in the identification of serosa invasion. MRI had a higher diagnostic yield than CT in several local staging parameters.

PURPOSE: Magnetic anal sphincter (MAS) augmentation is a novel surgical option for the treatment of fecal incontinence. Current clinical evidence is conflicting. The purpose of this meta-analysis was to report the safety profile, potential benefits, and the functional efficacy of this device. METHODS: The study followed the PRISMA guidelines. Literature databases (Medline, Scopus, Web of Science, CENTRAL) were screened for eligible articles. The primary endpoint was the pooled effect of MAS in the Cleveland Clinic Incontinence Score (CCIS) score. Quality evaluation was based on the ROBINS-I and Risk of Bias 2 tool. RESULTS: Overall, 8 studies with 205 patients were included. MAS resulted in a significant reduction of CCIS values (p = 0.019), and improvement only in the embarrassment domain of FIQoL scores (p = 0.034). The overall morbidity rate was 61.8%. Postoperative adverse events included MAS explantation in 12%, infection in 5.1%, pain in 10% and obstructed defecation in 5.8% of patients. CONCLUSION: The application of MAS in patients with fecal incontinence results in the improvement of some clinical parameters with a notable morbidity rate. Due to several study limitations, further, high-quality RCTs are required to delineate the efficacy and safety of MAS.

This meta-analysis was conducted to provide updated evidence regarding perioperative safety and efficacy, of IC and EC anastomosis in laparoscopic right colectomies. In this study, the Cochrane Handbook for Systematic Reviews of Interventions and the PRISMA guidelines were applied. The study protocol received a PROSPERO registration (CRD42020214596). A systematic literature search of the electronic scholar databases (Medline, Web of Science and Scopus) was performed. To reduce type I error, a trial sequential analysis (TSA) algorithm was introduced. The quality of evidence was evaluated based on the GRADE methodology. In total, 46 studies were included in this meta-analysis, Pooled comparisons and TSA confirmed that IC is superior in terms of incisional hernia (0.29; 95%CI: 0.19, 0.44), open conversion (0.45; 95%CI: 0.30, 0.67), reoperation (0.62; 95%CI: 0.46, 0.84]), LOS (- 0.76; 95%CI: - 1.03, - 0.49), blood loss (- 11.50; 95%CI: - 18.42, - 4.58), and cosmesis (- 1.71; 95%CI: - 2.01, - 1.42). Postoperative pain and return of bowel function were, also, shortened when the anastomosis was fashioned intracorporeally. The grading of most evidence ranged from 'low' to 'high'. Due to the discrepancy in the results of RCTs and non-RCTs, and the proportionally smaller sample size of the former, further randomized trials are required to increase the evidence of this comparison.

INTRODUCTION: Efficient postoperative pain control is important after hemorrhoidal surgery. Although several locally applied medications have been used, current evidence regarding the optimal strategy is still conflicting. This network meta-analysis assessed analgesic efficacy and safety of the various topical medications in patients submitted to excisional procedures for hemorrhoids. METHODS: The present study followed the Cochrane Handbook for Systematic Reviews of Interventions and the PRISMA guidelines. The last systematic literature screening was performed at 15 June 2023. Comparisons were based on a random effects multivariate network meta-analysis under a Bayesian framework. RESULTS: Overall, 26 RCTs and 2132 patients were included. Regarding postoperative pain, EMLA cream (surface under the cumulative ranking curve (SUCRA) 80.3%) had the highest ranking at 12-h endpoint, while aloe vera cream (SUCRA 82.36%) scored first at 24 h. Metronidazole ointments had the highest scores at 7 and 14 days postoperatively. Aloe vera had the best analgesic profile (24-h SUCRA 84.8% and 48-h SUCRA 80.6%) during defecation. Lidocaine (SUCRA 87.9%) displayed the best performance regarding overall morbidity rates. CONCLUSIONS: Due to the inconclusive results and several study limitations, further RCTs are required.

BACKGROUND: Gastrointestinal stromal tumors (GISTs) are considered the most common mesenchymal tumors of the gastrointestinal tract. Microvessel density (MVD) constitutes a direct method of vascularity quantification and has been associated with survival rates in multiple malignancies. AIM: To appraise the effect of MVD on the survival of patients with GIST. METHODS: This study adhered to Systematic reviews and Meta-Analyses guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. Electronic scholar databases and grey literature repositories were systematically screened. The Fixed Effects or Random Effects models were used according to the Cochran Q test. RESULTS: In total, 6 eligible studies were identified. The pooled hazard ratio (HR) for disease free survival (DFS) was 8.52 (95%CI: 1.69-42.84, P = 0.009). The odds ratios of disease-free survival between high and low MVD groups at 12 and 60 mo did not reach statistical significance. Significant superiority of the low MVD group in terms of DFS was documented at 36 and 120 mo (OR: 8.46, P < 0.0001 and OR: 22.71, P = 0.0003, respectively) as well as at metastases rate (OR: 0.11, P = 0.0003). CONCLUSION: MVD significantly correlates with the HR of DFS and overall survival rates at 36 and 120 mo. Further prospective studies of higher methodological quality are required.
RESUMO
PURPOSE: We designed this study to evaluate the impact of intraoperative intravenous lidocaine infusion on postoperative opioid consumption after laparoscopic cholecystectomy. METHODS: In total, 98 patients scheduled for elective laparoscopic cholecystectomy were included and randomized. In the experimental group, intravenous lidocaine (bolus 1.5 mg/kg and continuous infusion 2 mg/kg/h) was administered intraoperatively additionally to the standard analgesia, whereas the control group received a matching placebo. Blinding existed at the level of both the patient and the investigator. RESULTS: Our study failed to confirm any benefit in opioid consumption, during the postoperative period. Lidocaine resulted to reduced intraoperative systolic, diastolic, and mean arterial pressure. Lidocaine administration did not change postoperative pain scores or the incidence of shoulder pain, at any time endpoint. Moreover, we did not identify any difference in terms of postoperative sedation levels and nausea rates. CONCLUSION: Overall, lidocaine did not have any effect on postoperative analgesia after laparoscopic cholecystectomy.

PURPOSE: To investigate the association between redox status in erythrocytes and skeletal muscle with dietary nutrient intake and markers of physical fitness and habitual physical activity (PA). METHODS: Forty-five young physically active men were assessed for body composition, dietary nutrient intake, muscle strength, cardiorespiratory capacity and habitual PA. Blood and muscle samples were collected to estimate selected redox biomarkers. Partial correlation analysis was used to evaluate the independent relationship of each factor with redox biomarkers. RESULTS: Dietary cysteine intake was positively correlated (p < 0.001) with both erythrocyte (r = 0.697) and muscle GSH (0.654, p < 0.001), erythrocyte reduced/oxidized glutathione ratio (GSH/GSSG) (r = 0.530, p = 0.001) and glutathione reductase (GR) activity (r = 0.352, p = 0.030) and inversely correlated with erythrocyte protein carbonyls (PC) levels (r = - 0.325; p = 0.046). Knee extensors eccentric peak torque was positively correlated with GR activity (r = 0.355; p = 0.031) while, one-repetition maximum in back squat exercise was positively correlated with erythrocyte GSH/GSSG ratio (r = 0.401; p = 0.014) and inversely correlated with erythrocyte GSSG and PC (r = - 0.441, p = 0.006; r = - 0.413, p = 0.011 respectively). Glutathione peroxidase (GPx) activity was positively correlated with step count (r = 0.520; p < 0.001), light (r = 0.406; p = 0.008), moderate (r = 0.417; p = 0.006), moderate-to-vigorous (r = 0.475; p = 0.001), vigorous (r = 0.352; p = 0.022) and very vigorous (r = 0.326; p = 0.035) PA. Muscle GSSG inversely correlated with light PA (r = - 0.353; p = 0.022). CONCLUSION: These results indicate that dietary cysteine intake may be a critical element for the regulation of glutathione metabolism and redox status in two different tissues pinpointing the independent significance of cysteine for optimal redox regulation. Musculoskeletal fitness and PA levels may be predictors of skeletal muscle, but not erythrocyte, antioxidant capacity. TRIAL REGISTRATION: Registry: ClinicalTrials.gov, identifier: NCT03711838, date of registration: October 19, 2018.

PURPOSE: The aim of the present study was to evaluate the pooled efficacy of percutaneous tibial nerve stimulation (PTNS) in patients with low anterior resection syndrome (LARS). MATERIAL AND METHODS: This study was based on the Cochrane Handbook for Systematic Reviews of Interventions and the PRISMA guidelines. The primary endpoint was the pooled effect size of PTNS in LARS score (LARSS). Secondary endpoints included incontinence (Fecal Incontinence Score-FIC, Obstructive Defecation Syndrome-ODS), sexual functionality and quality of life (QoL) questionnaires, and manometric evaluations. Continuous outcomes were reported as weighted mean difference (WMD), with the corresponding 95% confidence interval (95% CI). Quality evaluation was performed via the National Institutes of Health (NIH) quality assessment tool. RESULTS: Overall, 5 studies were included. PTNS resulted to reduced LARSS values (WMD: - 5.68, 95%CI: - 7.73, - 3.63, p < 0.001). A similar effect was noted in St Mark's FIC (p < 0.001) and ODS (p = 0.02) score. An improvement in several QoL scales was found. There was no effect in sexual functionality and manometric measurements. Compared to sham, PTNS significantly improved LARSS. CONCLUSIONS: The application of PTNS in patients with LARS results in an improvement in multiple clinical parameters, including defecation functionality and quality of life. Due to several study limitations, further high quality RCTs are required to delineate the exact efficacy of PTNS.

PURPOSE: Defunctioning ileostomies are often performed during rectal cancer surgery. However, stomas are sometimes associated with complications, while 20-30% of them are never reversed. Additionally, ileostomy closure can have associated morbidity, with rates as high as 45%, with the respective literature evidence being scarce and conflicting. Thus, we evaluated the stoma reversal outcomes and the risk factors for non-closure after rectal cancer surgery. METHODS: This is a retrospective analysis of a prospectively collected database of all patients who had a defunctioning ileostomy at the time of resection for rectal cancer. All operations were performed by the same surgical team. A multivariable regression model was implemented. RESULTS: In this study, 129 patients (male: 68.2%, female: 31.8%) were included. Ileostomy formation was associated with a total of 31% complication rate. Eventually 73.6% of the stomas were reversed at a mean time to closure of 26.6 weeks, with a morbidity of 13.7%. Non-reversal of ileostomy was correlated with neoadjuvant CRT (OR: 0.093, 95% CI: 0.012-0.735), anastomotic leakage (OR: 0.107, 95% CI: 0.019-0.610), and lymph node yield (OR: 0.946, 95% CI: 0.897-0.998). Time to reversal was affected by the N status, the LNR, the need for adjuvant chemotherapy, and the histologic grade. CONCLUSION: In patients with rectal cancer resections, defunctioning stoma closure rate and time to closure were associated with several perioperative and pathological outcomes.

BACKGROUND: The aim of this study was to summarize the current evidence regarding the role of the Rafaelo procedure in the management of hemorrhoidal disease (HD). METHODS: This study was based on the Cochrane Handbook for Systematic Reviews of Interventions and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A literature search was performed (Medline, Scopus, CENTRAL, and Web of Science) from inception to 25/09/2022. Grey literature databases were also reviewed. The primary endpoint was the pooled complications rate of the Rafaelo procedure in patients with HD. Secondary endpoints included short- (bleeding, pain, thrombosis, necrosis, urinary retention, fever, oedema, anal fissure, and readmission) and long-term (stenosis, meteorism, constipation, anal tags, anal hyposensibility, reoperation, and recurrence) postoperative complication rates. Both prospective and retrospective studies were considered. Quality evaluation was performed via the ROBINS-I tool. Certainty of Evidence was based on the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology. RESULTS: Overall, 6 non-randomized studies and 327 patients were included. The overall complication rate was 17.6% (95% CI 8.8-26.3%). Short-term complications were bleeding (7.5%, 95% CI 2.5-12.5%), thrombosis (2.2%, 95% CI 0.4-4.8%), and pain (1.6%, 95% CI 0.2-3.3%). Reoperation and recurrence rates were 1.8% (95% CI 0.3-3.4%) and 4.8% (95% CI 1.2-8.4%), respectively. A significant improvement in the presenting symptoms was noted. Method approval and patient satisfaction rates were 89.1% (95% CI 81.7-96.6%) and 95% (95% CI 89.8-100%), correspondingly. Overall CoE was "Very Low". CONCLUSIONS: Further randomized controlled trials are required to delineate the exact role of the Rafaelo procedure in HD.

PURPOSE: The aim of this study was to validate the Greek version of the Strategic and Clinical Quality Indicators in Postoperative Pain Management (SCQIPP) questionnaire. DESIGN: The study was designed as a prospective questionnaire survey. METHODS: Overall, 210 elective surgical patients were included . SCQIPP consisted of 14 items that were scored on a five point scale. After the translation and linguistic adjustments, the tool was distributed to the surgical wards. Internal consistency reliability was assessed by Cronbach's alpha. The tool construct was generated by a principal axis factoring model with promax rotation. FINDINGS: Base Cronbach's alpha was 0.814. Due to low inter-item and item-total correlations and the increase of Cronbach's alpha (0.834) when item two was deleted, 13 items were included in the current tool version. Factor analysis identified three district subscales: nursing care, pain management, and support. Subscale and convergent validity were confirmed. The mean score of the validated tool was 55.2 (Range: 44-63). A low level of care was highlighted in most items. CONCLUSIONS: The Greek version of the SCQIPP questionnaire is a valid and efficient tool for the evaluation of the quality of care of postoperative pain management.

BACKGROUND: The introduction of minimal invasive principles in colorectal surgery was a major breakthrough, resulting in multiple clinical benefits, at the cost, though, of a notably steep learning process. The development of structured nation-wide training programs led to the easier completion of the learning curve; however, these programs are not yet universally available, thus prohibiting the wider adoption of laparoscopic colorectal surgery. AIM: To display our experience in the learning curve status of laparoscopic colorectal surgery under a non-structured training setting. METHODS: We analyzed all laparoscopic colorectal procedures performed in the 2012-2019 period under a non-structured training setting. Cumulative sum analysis and change-point analysis (CPA) were introduced. RESULTS: Overall, 214 patients were included. In terms of operative time, CPA identified the 110th case as the first turning point. A plateau was reached after the 145th case. Subgroup analysis estimated the 58th for colon and 52nd case for rectum operations as the respective turning points. A learning curve pattern was confirmed for pathology outcomes, but not in the conversion to open surgery and morbidity endpoints. CONCLUSION: The learning curves in our setting validate the comparability of the results, despite the absence of National or Surgical Society driven training programs.
RESUMO
In this trial, we evaluated the role of alginate dressings in the secondary intention wound healing and quality of life (QoL) after pilonidal sinus resection. The study was designed as a prospective randomised controlled trial (RCT). In the experimental group, alginate dressings with silver and high-G cellulose were introduced after elective pilonidal cyst excision, whereas in the control group, simple gauges were used. The primary end point was the difference in terms of the wound healing period. Blinding existed at the level of the investigator. Overall, 65 patients were included during the study period. Wound healing duration was comparable between the two groups (P = .381). No difference in postoperative pain scores or recovery outcomes was found. The experimental group was associated with reduced wound secretions at specific time end points. Similarly, no effect was identified, on overall Wound-QoL or SF-36 scores. Alginate dressings do not accelerate wound healing or improve QoL. Due to suboptimal sample size and several study limitations, further RCTs are required to confirm our findings.

Glomus tumors (GT) are rare mesenchymal tumors that develop in the subungual digital region. Extradigital GTs are very rare, with atypical clinical features. We report the case of a 63-year-old male with a five-year history of intermittent shoulder pain, where an excisional biopsy confirmed the diagnosis of a glomus tumor.
RESUMO
Cutaneous sarcomas are a heterogeneous group of rare mesenchymal neoplasms representing less than 1% of malignant tumors. Histology report remains the cornerstone for the diagnosis of these tumors. The most important clinicopathologic parameters related to prognosis include larger tumor size, high mitotic index, head and neck location, p53 mutations, depth of infiltration and histological grade, vascular and perineural invasion as well as the surgical margins status. Applying advanced biopsy techniques might offer more precise assessment of surgical margins, which constitutes a significant precondition for the management of these tumors. The management of cutaneous soft tissue sarcomas requires a multidisciplinary approach. Surgery remains the standard treatment, nonetheless adjuvant therapy may be required, consisting of radiotherapy, chemotherapy, and molecular targeted therapies to improve treatment outcomes. The role of molecular profiling in the treatment of uncontrolled disease is promising, but it may be offered to a relatively small proportion of patients and its use is still considered experimental in this setting. Due to the rarity of the disease, there is a need for knowledge and experience to be shared, pooled, organized and rationalized so that recent developments in medical science can have a major impact on the disease course. Multicenter clinical trials are needed to improve the care of patients with cutaneous sarcomas.

BACKGROUND/AIM: Current literature reports regarding the effect of lidocaine in laparoscopic colectomies are still inconclusive. The purpose of this study was to review the current literature and estimate the overall effect of intravenous lidocaine administration in postoperative recovery of patients submitted to laparoscopic colectomies. MATERIALS AND METHODS: This study was completed based on the PRISMA guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. A systematic screening using scholar databases was performed (Medline, Scopus, Web of Science, CENTRAL). RESULTS: In total, 8 studies and 407 patients were included in this meta-analysis. Introduction of intravenous lidocaine in the perioperative analgesia scheme did not improve hospitalization duration (p=0.23), morphine consumption (p=0.96), perioperative bowel function (first flatus p=0.40, first bowel opened p=0.13, first diet p=0.16), or the overall complication rates (p=0.42). Overall, high heterogeneity levels were identified. CONCLUSION: Current evidence indicates that lidocaine does not improve rehabilitation after laparoscopic colectomies.

PURPOSE: Never before the preoperative quality of life (QoL) score of colorectal cancer (CRC) patients was analyzed and linked directly to cancer staging according to pathology in specimens and, thereafter, in patients to estimate long-term prognosis. Our study attempted to give answers to these questions. METHODS: This was a prospective study of 80 elderly patients who underwent major colorectal surgery for cancer in a single University's surgical department conducted between 01/2018 and 12/2018. All patients aged >65 years, diagnosed with a resectable CRC without metastatic disease undergoing an elective surgery were prospectively included. As exclusion criteria were considered age <65 years, an emergency operation, non-resectable tumor, stage IV CRC and American Society of Anesthesiologists (ASA) score IV. All patients were asked to answer a self-administered questionnaire of the validated Greek version of the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30. RESULTS: Comparison of the mean score of EORTC QLQ-C30 showed stage I CRC was 87.62% (11.81%), 77.24% (12.91%) in stage II patients and 78.99% (15.25%) in stage III cancer. The mean difference between the three groups was statistically significant (p=0.002). Moreover, in post-hoc analysis, there was a statistically significant difference in the mean QLQ-C30 score between patients with stage I and stage II cancer (p=0.043) and between patients with stage I and stage III tumor (p=0.01), but this difference was not observed when comparing patients with stage II and III cancer (p=0.319). CONCLUSION: Our study demonstrated a significant association between preoperative QoL and tumor staging as shown in the specimen's examination in elderly patients with CRC. More prospective studies are needed to elucidate how QoL and its fluctuations during the postoperative period can be correlated with long-term survival and disease progression in elderly CRC patients.

INTRODUCTION: Gastrointestinal stromal tumors (GISTs) quite frequently occur synchronously with other malignancies, with most cases being adenocarcinomas. GISTs and liposarcomas are both of mesenchymal origin, and their coexistence is extremely rare. METHODS: We conducted a review of the current literature regarding the synchronous occurrence of GISTs and intra-abdominal liposarcomas. An electronic search of the literature was undertaken using MEDLINE (database provider PubMed). Furthermore, we present the first described case of an 86-year-old male with a GIST and synchronous liposarcoma, both located in the stomach, as well as a 66-year-old male with a gastric GIST and concurrent retroperitoneal liposarcoma. RESULTS: A total of 5 cases of synchronous GIST and intra-abdominal liposarcoma have been reported in the literature to date, with the most recent cases included in the present study. CONCLUSION: Further research is required to explain any possible correlation in the coexistence of these different neoplasms of the same origin. Meanwhile, R0 resection of both tumors remains the treatment of choice.

Background: Colectomies performed according to complete mesocolic excision with central vascular ligation (CME-CVL) principles have been associated with enhanced oncologic outcomes. Nonetheless, laparoscopic CME-CVL right hemicolectomy has not been widely adopted. We aimed to compare the perioperative and pathology outcomes of laparoscopic and open CME-CVL right hemicolectomy. Materials and Methods: We compared data from a prospectively collected database regarding patients who underwent either laparoscopic or open CME-CVL right hemicolectomy for nonmetastatic right colon cancer in a University Hospital, between January 2012 and December 2018. Results: A total of 130 consecutive patients were included in the study. Of them, 73 patients underwent laparoscopic and 57 patients open right colectomy, following the CME-CVL principles. The laparoscopic approach was associated with less hospital stay (6.6 versus 9.1 days; P < .001) and septic complications (P = .046), at a cost of an increased operative time (180 versus 125.1 minutes; P < .001). Patients treated with either open or laparoscopic approach presented similar outcomes regarding pathology endpoints. In fact, both groups demonstrated similar R0 resection rate (P = .202), number of harvested and positive lymph nodes (P = .751 and P = .734, respectively), number of harvested lymph nodes at the level of D1 and D2 lymph node dissection (P > .05), rate of vascular (P = .501), and perineural infiltration (P = .956). Furthermore, no difference was found regarding the rate of intact mesocolic plane (P = .799), along with the tumor diameter (P = .154) and the length of specimen (P = .163). Conclusion: Laparoscopic CME-CVL right hemicolectomy appears to offer certain advantages in short-term outcomes compared to open procedure. Pathology outcomes did not differ between the two approaches. Future studies should further evaluate their long-term outcomes.

PURPOSE: The aim of this study is to evaluate the role of pelvic intraoperative neuromonitoring (pIONM) in rectal cancer surgery. METHODS: A systematic review of the literature and a meta-analysis were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. RESULTS: Overall, nine studies were identified. Quantitative analysis was performed only in three trials. Bilateral pIONM improved postoperative anorectal and urogenital functional outcomes. However, unilateral pIONM displayed a significant effect only on erectile function (p = 0.001). CONCLUSIONS: Our findings suggest a positive effect of pIONM on postoperative functional outcomes and quality of life after rectal cancer surgery. Due to several limitations, further trials are required in order to elucidate the exact role of pIONM.
