A prospective subanalysis was conducted on a cohort from the ADiFAS study, which originally included 1099 patients. After excluding 289 patients who did not meet the inclusion criteria, 810 patients remained for analysis. From this cohort, 330 patients with AD and pericolic free gas were selected using propensity score matching and divided into two age groups: < 65 years and ≥ 65 years. The groups were matched based on sex, BMI, diabetes mellitus (DM), cardiovascular disease, previous episodes of AD, and the presence of free fluid on CT scan. Data were assessed for Hinchey classification, surgical procedures, complications, and the frequency of surveillance through colonoscopy and CT scans. The study found a significantly higher rate of surgery in the older group during the index episode (17% vs. 4.2%, p = 0.000). A higher proportion of patients in the older group were misclassified as Hinchey II (18.2% vs. 6.4%, p = 0.007) and Hinchey III (2.3% vs. 0.7%, p = 0.304). All patients classified as Hinchey III (1 in the younger group and 3 in the older group) underwent emergency surgery. In the younger group, 2 out of 8 emergency surgeries were for patients classified as Hinchey II, compared to 11 out of 28 in the older group. Only 58% of patients underwent any form of imaging or endoscopic surveillance during the first year of follow-up. Among those, complications such as abscess, fistula, or stenosis were observed in 17% of patients, occurring more frequently in the older group (16.9% vs. 5.7%, p = 0.089). Nearly 50% of these patients required surgery, with 6 cases in the younger group and 9 in the older group. Emergency surgeries were more common in the older group (2.4% vs. 0.6%, p = 0.186), as was elective surgery (10.3% vs. 7.9%, p = 0.283). A conservative approach, combined with meticulous monitoring through regular follow-ups and imaging, can be effectively employed in managing patients with acute diverticulitis and pericolic free gas. However, our findings highlight the critical need for rigorous surveillance, especially in older patients, due to the higher prevalence of long-term complications.</p>","PeriodicalId":23391,"journal":{"name":"Updates in Surgery","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144143569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Key strategies include the use of 4/0 PDS stitches to control pancreatic vessel bleeding, preventing ischemia by refraining from the use of energy during pancreas dissection, and ensuring optimal drainage placement. The incorporation of a modified Blumgart anastomosis with a single-thread technique and the use of hydrogel sheets are also highlighted as crucial in reducing fistula formation.

This study aims to evaluate the expression of programmed death ligand 1 (PD-L1) in a selected cohort of intentionally curative resected thymomas and evaluate a possible relationship with the risk of recurrence. This retrospective bicentric study analyzed a group of patients who underwent complete thymectomy with curative intent. PD-L1 expression was assessed through immunohistochemistry using the Ventana PD-L1 assay. PD-L1 expression was assessed as low if <50% or high when ≥50%. The Kaplan-Meier method and Cox regression analysis were performed to evaluate a possible relationship between PD-L1 expression and disease-free survival. High PD-L1 expression was observed in 46.2% of patients. Overexpression of this protein was significantly associated with aggressive (B2/B3) thymomas histotypes (p<0.001). During follow-up period, 12/52 patients developed recurrence. High PD-L1 expression correlated with reduced disease-free survival with Kaplan-Meier method (p<0.001). Furthermore, PD-L1 expression more than 50% resulted to be related to a worse prognosis at multivariable Cox regression analysis (hazard ratio 5.4, 95% confidence interval 1.5-16.9, p=0.028) together with histology (p=0.044) and Masaoka-Koga stage (p=0.026). The elevated expression of PD-L1, particularly in aggressive thymoma subtypes, underscores its potential as a prognostic biomarker.

The Joanna Briggs Institute checklist was used to assess bias. (PROSPERO: 298486). Of 2155 records, eight cohort studies were included, showing low to moderate risk of bias but high heterogeneity. Two studies on hysterectomy found robotic surgery had the highest carbon footprint (12.0-40.3 kgCO_2e) compared to laparoscopic (10.7-29.2 kgCO_2e) and open surgery (7.1-22.7 kgCO_2e). Another study found laparoscopic prostatectomy produced more emissions than robotic surgery (59.7 vs. 47.3 kgCO_2e) due to higher disposable devices, surgery time and length of stay. Single-use devices in laparoscopic cholecystectomy emitted more CO_2e than hybrid devices (7.194 vs. 1.756 kgCO_2e). CO₂ used in minimally invasive surgery had negligible environmental effects (0.9 kgCO_2e). Qualitative subgroup analyses revealed significant differences between surgery types and measurement methodologies, contributing to data heterogeneity. Minimally invasive surgeries often have higher carbon footprints due to disposable tools and waste.
