Background/Objectives: To identify independent predictors of free peritoneal cancer cells (FPCC), and to investigate survival outcomes relative to peritoneal cytology status among patients who underwent intended curative gastrectomy for adenocarcinoma of the stomach or esophagogastric junction. Methods: Medical records of patients who underwent radical surgery between January 2005 and December 2020 were retrospectively reviewed. Clinical data and cytology results were evaluated. Multivariate Cox regression analysis was used to identify independent predictors of FPCC. Kaplan–Meier survival analysis was used to estimate disease recurrence and survival outcomes. Results: Out of the 349 enrolled patients, 188 (53.8%) had negative cytology, 32 (9.2%) were positive, and 129 (36.9%) showed atypical cells in peritoneal cytology. Poor differentiation (adjusted odds ratio [aOR]: 2.63, 95% confidence interval [95%CI]: 1.04–6.82; p = 0.015), pT4 (aOR: 4.62, 95%CI: 1.28–14.34; p = 0.018), pN3 (aOR: 4.13, 95%CI: 1.14–15.03; p = 0.031), and metastatic lymph node ratio >0.40 (aOR: 6.49, 95%CI: 1.44–29.14; p = 0.015) were independent predictors of FPCC. Median overall survival was 34.1 months in the negative group, 13.1 months in the positive group, and 28.7 months in the atypical cell group (p < 0.001). Median time to disease recurrence was 20.5, 4.9, and 11.3 months, respectively (p < 0.001). Survival and recurrence outcomes in the atypical cell group were comparable to those with negative cytology. Conclusions: Poorly differentiated histology, pT4, pN3, and metastatic lymph node ratio >0.40 are independent predictors of FPCC, which is significantly associated with poor survival and disease recurrence outcomes. These findings suggest that high-risk patients may benefit from routine peritoneal cytologic screening during surgery to improve risk stratification and guide postoperative treatment planning.

Background: Pulmonary hypertension is common in left-sided heart valve disease, with historical studies reporting mortality rates up to 31% in severe cases undergoing mitral valve surgery. This study evaluates the impact of severe pulmonary hypertension on outcomes of mechanical mitral valve replacement with posterior leaflet preservation by comparing results with patients having mild-to-moderate pulmonary hypertension. Methods: Prospective analysis of 86 patients with mitral valve disease undergoing mechanical valve replacement with posterior leaflet preservation from March 2015 to September 2016 was conducted. Patients were stratified by pulmonary artery pressure: severe (≥60 mmHg, n = 19) versus mild–moderate (35–59 mmHg, n = 67). Primary outcomes included mortality, complications, and functional recovery at 1, 6, and 12 months. Results: The cohort included 67 patients (77.9%) with mild–moderate pulmonary hypertension and 19 patients (22.1%) with severe pulmonary hypertension. Severe pulmonary hypertension patients demonstrated higher NYHA functional class (73.7% class III vs. 46.2%, p = 0.03), larger left atrial diameter (56.3 ± 9.8 vs. 49.5 ± 6.7 mm, p = 0.01), and higher mean pressure gradients (14.4 ± 5.3 vs. 11.3 ± 5.0 mmHg, p = 0.025). Mortality was 5.3% in the severe group versus 0% in the mild–moderate group (p = 0.331). Patients with severe pulmonary hypertension required longer ICU stays (6.3 ± 3.7 vs. 4.7 ± 2.2 days, p = 0.024) but showed no significant differences in ventilation time, reoperation rates, or major complications. At the 12-month follow-up, both groups achieved equivalent outcomes in pulmonary artery pressures, left ventricular function, and cardiac dimensions. Conclusion: In this study with a relatively small sample size, severe pulmonary hypertension was associated with significantly longer intensive care unit stay but not with higher mortality compared to mild–moderate pulmonary hypertension, with both groups attaining comparable functional and hemodynamic parameters at 12 months after mechanical mitral valve replacement with posterior leaflet preservation.

Background: Upper eyelid blepharoplasty is one of the most common aesthetic surgeries performed worldwide. The procedure consists of removing excess skin with or without muscle and/or fat from the upper eyelid by a transcutaneous approach and placement of a supratarsal crease. The surgery is performed in a cosmetically sensitive area and every attempt to avoid poor scar formation should be made. Methods: This review presents a conspectus of the existing medical literature regarding scar-avoiding strategies in upper blepharoplasty with the aim of contributing to the reduction in postoperative scar formation. The Medline, Embase, and Cochrane databases were searched on 2 September 2025. Results: The search yielded a total of 562 records, and, following screening, eleven publications were included. Conclusions: A systematic approach to pre-, intra-, and postoperative measures to minimize scarring are presented. There is a need to standardize scar assessment and reporting to facilitate inter-study comparison of effects, as well as prospective, randomized studies comparing suture materials and techniques.

Background/Objectives: Ultrasound-guided carpal tunnel release (UGCTR) has emerged as a minimally invasive alternative to open surgery for the treatment of carpal tunnel syndrome (CTS). This study aimed to evaluate the clinical outcomes, complication rates, and recovery profiles associated with UGCTR in a large multicenter cohort. Methods: A retrospective observational study was conducted across Italian hand surgery centers, including 735 patients who underwent UGCTR between January 2012 and April 2025. Data were collected on demographics, comorbidities, ultrasound measurements, and surgical outcomes. Primary endpoints included pain (measured using the Visual Analog Scale [VAS]), symptom severity and function (assessed via the Boston Carpal Tunnel Questionnaire [BCTQ]), complication rates, time to return to daily activities (RDA), and return to work (RTW). Follow-up assessments were performed at 1, 4, and 12 weeks postoperatively. Results: A significant improvement in pain was observed, with mean VAS scores decreasing from 6.37 preoperatively to 0.58 at 12 weeks. The mean cross-sectional area (CSA) of the median nerve decreased from 12.81 mm2 to 8.83 mm2 at 4 weeks. Both the BCTQ Symptom Severity Scale (BCTQ-SS) and Functional Status Scale (BCTQ-FS) scores showed significant improvement by week 1. The mean RDA was 5.7 days, and RTW was 14.5 days. Complication rates were low and decreasing over time, from 8.7% at 1 week to 3.4% at 12 weeks. Conclusions: UGCTR is a safe and effective technique for the treatment of CTS, offering rapid functional recovery and a favorable complication profile. Its feasibility in outpatient settings and potential for cost-effectiveness support its role as a viable alternative to open surgery and as a model of image-guided, minimally invasive intervention.

Background: Lumbar foraminal stenosis (LFS) is a prevalent degenerative condition associated with significant radicular pain and impaired quality of life. Advances in minimally invasive and fusion-based surgical techniques have introduced new strategies for decompressing the neural elements. However, comparative data correlating volumetric foraminal expansion with functional outcomes remain limited. Methods: This retrospective cohort study analyzed 256 patients treated surgically for symptomatic LFS between December 2017 and December 2023. Patients were categorized into four surgical subgroups: endoscopic decompression, anterior lumbar interbody fusion (ALIF), microsurgical decompression, and transforaminal lumbar interbody fusion (TLIF). Preoperative and postoperative assessments included magnetic resonance imaging (MRI) to calculate foraminal volume and standardized clinical scales: the Oswestry Disability Index (ODI), Visual Analogue Scale (VAS) for back and leg pain, and SF-36 health-related quality-of-life scores. Statistical significance was determined using p-values, and inter-observer agreement was evaluated via κ-statistics. Results: Postoperative imaging demonstrated a significant increase in foraminal canal volume across all surgical groups: endoscopy (29.9%), ALIF (71.8%), microsurgery (48.06%), and TLIF (67.0%). ODI scores improved from a preoperative mean of 55.25 to 18.27 at 24 months post-surgery (p < 0.001). VAS scores for back pain decreased from 6.37 to 2.1 (p < 0.001), while leg pain scores declined from 6.85 to 2.05 (p < 0.001). Functional improvement reached or exceeded the minimal clinically important difference (MCID) threshold in over 66% of patients. Conclusions: Modern surgical strategies for LFS, particularly fusion-based techniques, yield significant volumetric decompression and durable clinical improvement. Volumetric gain in the foraminal canal is closely associated with pain reduction and enhanced functional outcomes. These findings support a tailored surgical approach based on anatomical pathology and segmental stability.

Background and Objectives: Effective pain management is essential for optimizing recovery after laparoscopic cholecystectomy (LC). Ultrasound-guided erector spinae plane (ESP) and transversus abdominis plane (TAP) blocks are validated techniques, but may be limited by equipment requirements and technical complexity. This study aimed to evaluate whether surgeon-delivered local anesthetic infiltration provides comparable analgesic efficacy. Materials and Methods: This prospective, randomized, controlled, single-center trial enrolled 172 patients undergoing elective LC between November 2020 and June 2022. Patients were randomized into four groups: Group A—surgeon-delivered port-site and intraperitoneal bupivacaine infiltration; Group B—ESP block; Group C—TAP block; and Group D—control. Primary outcomes were postoperative pain assessed by Visual Analog Scale (VAS) scores at 1, 3, 6, 12, and 24 h, and Behavioral Pain Scale (BPS) scores at 1 and 3 h. Secondary outcomes included 24 h tramadol consumption, patient satisfaction, additional rescue analgesia requirement, and procedure duration. Results: All intervention groups (A–C) demonstrated significantly lower VAS and BPS scores compared to controls (VAS at 24 h: 1.8 ± 0.9 vs. 2.8 ± 1.3, p < 0.001). Tramadol use was also reduced (≈82 mg vs. 97 mg, p < 0.001), with fewer opioid-related adverse effects. No significant differences were observed among Groups A–C. Patient satisfaction was higher in the intervention groups, and no major complications were reported. Conclusions: Surgeon-delivered local infiltration achieved analgesic efficacy equivalent to ESP and TAP blocks. Considering its simplicity, safety, and minimal resource demands, this method may represent a practical alternative for enhanced recovery pathways following LC.

Background/Objectives: Surgical site infections (SSIs) following pancreaticoduodenectomy contribute to significant morbidity and healthcare costs. Negative pressure wound therapy (NPWT) has emerged as a potential preventive intervention; however, evidence regarding its efficacy in pancreatic surgery remains limited. This systematic review and meta-analysis aimed to evaluate the efficacy of NPWT compared to conventional dressings in preventing SSI following pancreaticoduodenectomy. Methods: PubMed, Scopus, BASE, Cochrane CENTRAL, and ClinicalTrials.gov were systematically searched from their inception to 2 April 2025. Randomized clinical trials and observational studies comparing NPWT with conventional dressings in patients undergoing pancreaticoduodenectomy were included. Two independent reviewers extracted the data and assessed the methodological quality. Random-effects meta-analysis was performed to calculate the pooled relative risks (RRs) with 95% CIs. The primary outcome was the incidence of SSI. The secondary outcomes included pancreatic fistula, seroma formation, incisional hernia, and readmission rates. Results: Nine studies (three randomized clinical trials and six observational studies) comprising 1247 patients were included. NPWT was associated with a significant reduction in SSI compared with conventional dressings (RR, 0.61; 95% CI, 0.41–0.90). Subgroup analysis revealed varying effects by study design: retrospective cohort studies showed a nonsignificant trend toward SSI reduction (RR, 0.53; 95% CI, 0.19–1.48), randomized clinical trials demonstrated a nonsignificant trend favoring NPWT (RR, 0.67; 95% CI, 0.37–1.23), and the single prospective cohort study showed significant SSI reduction (RR, 0.48; 95% CI, 0.28–0.84). No significant differences were observed in pancreatic fistula rates between the NPWT and conventional dressing groups. Prophylactic NPWT application, longer duration (≥5 days), and higher negative pressure settings (−125 mmHg) appeared more effective than therapeutic application, shorter duration, and lower-pressure settings, respectively. Conclusions: This systematic review and meta-analysis suggests that NPWT is associated with a reduced SSI risk following pancreaticoduodenectomy. The greatest benefit may be achieved with prophylactic application in high-risk patients, longer therapy duration, and higher negative pressure settings. These findings support the consideration of NPWT as part of SSI prevention strategies in pancreatic surgery, particularly for patients with identified risk factors.

Background/Objectives: Machine learning has been suggested as a way to improve how we predict anesthesia-related complications after surgery. However, many studies report overly optimistic results due to issues like data leakage and not fully using information from clinical notes. This study provides a transparent comparison of different machine learning models using both structured data and preoperative notes, with a focus on avoiding data leakage and involving clinicians throughout. We show how high reported metrics in the literature can result from methodological pitfalls and may not be clinically meaningful. Methods: We used a dataset containing both structured patient and surgery information and preoperative clinical notes. To avoid data leakage, we excluded any variables that could directly reveal the outcome. The data was cleaned and processed, and information from clinical notes was summarized into features suitable for modeling. We tested a range of machine learning methods, including simple, tree-based, and modern language-based models. Models were evaluated using a standard split of the data and cross-validation, and we addressed class imbalance with sampling techniques. Results: All models showed only modest ability to distinguish between patients with and without complications. The best performance was achieved by a simple model using both structured and summarized text features, with an area under the curve of 0.644 and accuracy of 60%. Other models, including those using advanced language techniques, performed similarly or slightly worse. Adding information from clinical notes gave small improvements, but no single type of data dominated. Overall, the results did not reach the high levels reported in some previous studies. Conclusions: In this analysis, machine learning models using both structured and unstructured preoperative data achieved only modest predictive performance for postoperative complications. These findings highlight the importance of transparent methodology and clinical oversight to avoid data leakage and inflated results. Future progress will require better control of data leakage, richer data sources, and external validation to develop clinically useful prediction tools.

(1) Background: trays are surgery-specific sets of required materials and medical devices, assembled in consultation between manufacturer and user, and provided in a sterile package. (2) Methods: in a high-volume urological center performing 11,920 operations/procedures annually (2023), we prospectively evaluated the effect of trays compared with the standard approach in a comparative study of 64 operations conducted between 29 October and 30 November 2024. The primary endpoints were the amount of operating room (OR) waste (volume/cm3, weight/g) and setup time (minutes). The secondary endpoint was the workflow assessment by nursing staff, rated on a numerical score (0–10) across seven relevant domains. (3) Results: for endourological procedures, setup time was reduced by 35%, operating room (OR) waste by 34%, and waste volume by 19.0%. Workflow was positively rated with a mean score of 9.75/10. For major open procedures, setup time was reduced by 43%, waste weight by 24.8%, and waste volume by 32%. Workflow was positively rated with a mean score of 8.9/10. (4) Conclusions: Trays have a sustainable and significant impact on reducing OR waste, save nursing staff preparation time, and facilitate improved workflow in the operating room.

Background: Hemorrhoids and anal fissure are among the most common benign anorectal conditions. The incidence of synchronous symptomatic hemorrhoids and chronic anal fissure is unknown. In this study we evaluated the outcomes of our experience with concomitant surgical treatment for both these conditions. Methods: In this retrospective study we included consecutive patients who underwent surgical treatment for symptomatic hemorrhoids combined with lateral internal sphincterotomy for chronic anal fissure, during a time period of over 5 years. Eligible patients were contacted by phone and were asked to answer a questionnaire to evaluate recurrent symptoms, fecal incontinence, satisfaction, and improvement in quality-of-life. Results: A total of 56 patients were included, and 29 (51.8%) were female; the mean age was 46.9 ± 13.7 years, and the median follow-up time was 45.4 months. The median self-assessed improvement in quality-of-life on a scale of 0–10 was 10 [IQR 8, 10]. No significant differences were observed in satisfaction or self-assessed improvement in quality-of-life between genders or across different surgical procedures for hemorrhoids. Conclusions: Patients who underwent concomitant surgical treatment for hemorrhoids and chronic anal fissure were satisfied. This study supports our approach for synchronous treatment for different anorectal pathologies given the right patient selection, being safe and feasible.
