Abstract	Objectives: This study aims to compare students' subjective perceptions and objective results by comparing two methods of crown preparation: typodonts and haptics. Materials and methods: Fifty-four second-year students were given instructions on crown preparation for the upper right second premolar. First on typodonts and then with haptics. They were given five minutes to familiarize with the artificial environment and then thirty minutes for the actual preparation. Finally, they completed a questionnaire about their experience. Their preparations were objectively compared by measuring the angle of total occlusal convergence-TOC on the typodonts and with haptics. Results: Students reported that haptics can enhance the learning process and that they would use them for skill training in the future. Overall, their experience was rated as positive. The TOC of teeth prepared with haptics was significantly higher than those prepared with typodonts, but all values were within the acceptable range. Conclusion: Although students did not prefer haptics to typodonts, haptics appear to be a powerful tool in the educational process because it can be a complementary option to traditional methods at the preclinical level.

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	Purposes: The management of patients with iatrogenic bile duct injuries (IBDI) is a challenging field, often with dismal medico legal projections. Attempts to classify IBDI have been made repeatedly and the final results were either analytical and extensive but not useful in everyday clinical practice systems, or simple and user friendly but with limited clinical correspondence approaches. The purpose of the present review is to propose a novel, clinical classification system of IBDI by reviewing the relevant literature. Methods: A systematic literature review was conducted by performing bibliographic searches in the available electronic databases, including PubMed, Scopus, and the Cochrane Library. Results: Based on the literature results, we propose a five (5) stage (A, B, C, D and E) classification system for IBDI (BILE Classification). Each stage is correlated with the recommended and most appropriate treatment. Although the proposed classification scheme is clinically oriented, the anatomical correspondence of each IBDI stage has been incorporated as well, using the Strasberg classification. Conclusions: BILE classification represents a novel, simple, and dynamic in nature classification system of IBDI. The proposed classification focuses on the clinical consequences of IBDI and provides an action map that can appropriately guide the treatment plan.

Abstract	Gastric cancer patients represent a rather divergent patient group and in certain carefully selected cases of early forms of gastric cancer the D2 gastrectomy could be considered a more radical procedure than the biological and oncological characteristics of the primary tumor on the gastric wall would require. As any unnecessary dissection increases morbidity without always respective survival benefits, an approach that could accurately predict and actually dictate the exact extent of lymph node dissection would be ideal. It is more than logical the assumption that the standard D2 lymphadenectomy could represent an overtreatment in distinct patients groups such as patients with early gastric cancer with favorable pathological characteristics and clinically negative nodes not suitable for endoscopic treatment because this early stage disease shows limited lymph node metastasis incidence and excellent overall survival. Considering that the D2 gastrectomy has a negative impact on the quality of life of gastric cancer patients due to the post-gastrectomy functional results, a concept of a more targeted lymph node dissection, when appropriate, is certainly appealing. It is yet to be proven whether sentinel lymph node navigation surgery can fulfill such expectations providing the appropriate balance between morbidity and oncological safety in selected gastric cancer patients.

Abstract	Pancreaticoduodenectomy is the procedure of choice for benign or malignant tumors of the periampullary region. The preservation of the pylorus has been established as the mostly utilized approach during pancreaticoduodenectomy among the majority of specialized, in the surgical treatment of pancreatic cancer, centers worldwide. The factors that influenced this predilection are the shorter operation times, the less intraoperative blood loss, the decreased technical difficulty, and the quite similar short- and long-term outcomes compared to the classic Whipple. However, there is a notable trend in the literature highlighting the increased incidence of delayed gastric emptying following pylorus preserving pancreaticoduodenectomy. Among other factors, pylorus dysfunction attributable to the surgical maneuvers has been implemented in the etiology of this complication. In an attempt to overcome this limitation of the pylorus preserving pancreaticoduodenectomy, pylorus resecting pancreaticoduodenectomy with the preservation of the stomach was proposed. In theory, pylorus resecting pancreaticoduodenectomy could maintain the advantages of organ sparing surgery, but at the same time guarantee a more seamless gastric emptying. Only three RCTs, to date, aimed to evaluate the approach with only one reporting results in favor of the pylorus resecting pancreaticoduodenectomy in regard to the incidence of delayed gastric emptying. Further well-designed prospective randomized studies are needed for an accurate assessment of the true role of each of these surgical alternatives on the treatment of pancreatic cancer.

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	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.

Abstract	In order to delineate the exact role of bursectomy (BS) in gastric cancer surgery, we designed and conducted the present meta-analysis. This meta-analysis adhered to the PRISMA guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. A systematic literature review of the electronic databases (Medline, Scopus, Web of Science) was performed. Trial sequential analysis (TSA) was introduced for the validation of the pooled analyses. The level of evidence was attributed based on the GRADE approach. Overall, nine studies and 3599 patients were included in our meta-analysis. BS did not lead to an increase in the overall morbidity rate (OR 1.17, 95% CI 0.97-1.42, p = 0.09). Equivalence was, also, identified in all specific postoperative complications. Similarly, mortality rates were comparable (p = 0.69). Moreover, BS was related to a significantly higher operative time (p < 0.001) and perioperative blood loss (p = 0.002). Finally, resection of the omental bursa was not associated with improved R0 excision rates (p = 0.92), lymph node harvest (p = 0.1) or survival outcomes (OS p = 0.15 and DFS p = 0.97). BS displayed a suboptimal perioperative performance without any significant oncological efficacy. Due to certain limitations and the low level of evidence, further high-quality RCTs are required.
