    Abstract 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.

    Abstract Introduction: We conducted this meta-analysis, to compare cecorectal (CRA) and ileorectal anastomosis (IRA), regarding perioperative safety and efficacy, in patients submitted to colectomy for refractory slow transit constipation (STC).
    Methods: This study followed the Cochrane Handbook for Systematic Reviews of Interventions and the PRISMA guidelines. To identify all eligible records, a systematic literature search in the electronic scholar databases (Medline, Scopus, Web of Science) was performed.
    Results: Overall, 5 trials and 291 patients were included in this meta-analysis. Pooled comparisons confirmed the comparability of the two techniques regarding perioperative complications (p = 0.55). CRA was associated with a shorter operation (p = 0.0004) and hospitalization duration (p = 0.001). Although there was no difference in terms of gastrointestinal symptoms, functional outcomes, and patient satisfaction, CRA resulted in lower long-term Wexner scores (p < 0.0001).
    Conclusion: Due to several study limitations, further large-scale RCTs are required to verify the findings of the present meta-analysis.

    Abstract A meta-analysis was conducted to provide an up-to-date comparison of single-port and multi-port approach, in laparoscopic inguinal hernia mesh repair. This meta-analysis was performed on the basis of the PRISMA guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. The electronic databases (MEDLINE, Web of Science and Cochrane Central Register of Controlled Clinical Trials) were systematically screened. Fixed Effects or Random Effects model was used, according to the Cochran Q test. In total 16 eligible studies were found. There was no statistically significant difference, regarding unilateral operation duration, between the two approaches, in TEP (OR - 4.61; 95% CI - 9.70, 0.47, p = 0.08) or TAPP (OR - 1.96; 95% CI - 4.89, 0.97, p = 0.19) procedures. Similarly, in both operative modalities, no superiority of either approach was proven, in terms of conversion rate (TEP OR 0.69, p = 0.48; TAPP OR 5.46, p = 0.31), length of hospital stay (TEP WMD 0.00, p = 0.76; TAPP WMD - 0.11, p = 0.42) and overall complication rate (TEP OR 1.10, p = 0.51; TAPP OR 0.74, p = 0.43). Overall, single-port and the established multi-port approach in inguinal hernia mesh repair, are equivalent, regarding the postoperative outcomes. Given several limitations, further RCTs, of higher methodological and quality level are required.

    Abstract Background: Anastomotic leak (AL) following colorectal surgery can be a life-threatening complication. The use of a diverting stoma has been proposed, to prevent or reduce morbidity and mortality associated with AL. Stomas, however, have their own distinct complications. Thus, virtual ileostomy (VI) has been proposed as an alternative to diverting stoma. The aim of the present study was to further evaluate the role of VI through systematic review of existing literature.
    Methods: A systematic review of the literature was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the Cochrane handbook for systematic reviews of interventions. The primary endpoint of our study was the estimation of the overall VI complication rate. Secondary endpoints included the identification of the VI-specific adverse outcomes, perioperative endpoints such as the length of hospital stay, transfusion and postoperative leak rates, description of the operative variations of VI reported VI operative variations and details regarding the primary operation and previous neoadjuvant therapy.
    Results: In total, 11 studies and 554 patients were included in this systematic review. Overall, 158 laparoscopic and 191 open procedures were performed. The AL and VI conversion rates were 11.9% and 10.46%, respectively. The total complication rate was estimated to be 13.9%, while VI-specific adverse events were recorded in 2.1% of all cases.
    Conclusions: VI could be a safe and effective alternative to a diverting stoma. Although currently, VI is not widely used, it could have a widespread application in laparoscopic surgery. However, definitive trials are needed before firm recommendations on the use of VI can be made.

    Abstract Purpose: The aim of the present study was to evaluate the effect of the anesthesia type on the postoperative quality of life in patients who underwent trans-abdominal pre-peritoneal (TAPP) inguinal hernia repair.
    Methods: In this study, 70 patients submitted to TAPP for inguinal hernia repair, were randomized between spinal and general anesthesia. Overall, 58 patients completed the follow-up process and were, therefore, included. The quality of life evaluation was based on the SF-36 questionnaire. Significance was considered at the level of P < 0.05 RESULTS: General anesthesia was applied to 31 patients, whereas 27 operations were performed under spinal anesthesia. Except gender, the two study subgroups were similar in terms of demographics. Although spinal anesthesia displayed higher energy, emotional health, and general health scores these findings were not statistically significant. A positive correlation was identified between age and physical and emotional role. Operative time was associated with the estimated energy and general health.
    Conclusion: Our study could not identify a difference between spinal and general anesthesia on the postoperative quality of life. Spinal anesthesia is as effective as general anesthesia and remains an attractive anesthetic alternative for TAPP inguinal hernia repair. Given several study limitations, further high-quality trials are required.

    Abstract Purpose: The purpose of the present study was a comparison of the systemic inflammatory response intensity through the estimation of C- reactive protein and albumin levels before and after open tension free inguinal hernia repair performed under different anesthetic alternatives.
    Patients and methods: Totally, 125 inguinal hernia patients scheduled for unilateral primary open tension free inguinal repair unRomader local (50 patients), spinal (50 patients) and general anesthesia (25 patients) have been included in this prospective study.
    Results: The group of local anesthesia was associated with the higher postoperative serum levels of albumin compared to the group of general anesthesia (P 0.013). Local anesthesia was also associated with higher postoperative serum albumin levels compared to regional anesthesia but however the difference was not statistically significant (P 0.282). The group of local anesthesia was also associated with the lower postoperative levels of CRP compared to the regional (P 0.0094) and general anesthesia (P 0.0009) groups.
    Conclusion: Local anesthesia proved superior to regional or general anesthesia for open tension free inguinal hernia repair in the given patient sample from the standpoint of the inflammatory and acute phase response.

    Abstract 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.

    Abstract 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.

    Abstract 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.

    Abstract 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.
