Laparoscopic ventral mesh rectopexy (LVMR) and laparoscopic posterior mesh rectopexy (LPMR) are two common abdominal approaches globally practiced. However, comparative data from South Asia is still scarce. The purpose of this study was to compare recurrence and functional outcomes after LVMR versus LPMR. A prospective, non-randomized comparative cohort study was carried out at a tertiary care facility, including patients who underwent laparoscopic mesh rectopexy for FTRP between January 2023 and June 2024, followed for 12 months and follow-up was completed in June 2025. Baseline demographics were comparable between groups. The Cleveland Clinic Constipation Score (CCCS) and Wexner Fecal Incontinence Score (FIS) were used to measure functional outcomes. Recurrence at 12 months was the primary outcome. Functional improvement (ΔCCCS, ΔFIS), operative parameters, and perioperative morbidity were secondary outcomes. SPSS version 25 was used to perform statistical analysis, and p < 0.05 was considered statistically significant. Sixty-five patients with comparable baseline demographics were analyzed (LVMR n = 32; LPMR n = 33). 3.1% (n = 1) of LVMR and none of LPMR patients experienced recurrence at 12 months (p = 0.492) with absolute risk difference of 3.1% points (95% CI, - 9.9 to 15.7). Given the single recurrence event, the comparative analysis of recurrence was considered exploratory. The LVMR group had a considerably longer operative time (188.8 ± 7.0 vs. 120.9 ± 10.2 min, p < 0.001). At 12 months, both approaches showed a significant within-group improvement in CCCS and FIS (p < 0.001). Greater improvement in functional scores was shown in LVMR group (ΔCCCS 8.75 ± 1.76 vs. 7.21 ± 1.54, p < 0.001; ΔFIS 6.72 ± 1.53 vs. 5.58 ± 1.58, p = 0.004) than in the LPMR group, with between-group differences of 1.54 and 1.14 points, respectively. The incidence of complications, length of hospital stay, and estimated blood loss did not differ considerably between groups. Our results are consistent with global literature indicating better improvement in functional recovery scores with LVMR, most likely as a result of avoiding posterior rectal mobilization and preserving autonomic nerves. Improved constipation and continence scores support the ventral approach, despite the longer operative time. However, both techniques are safe choices. For FTRP, both LVMR and LPMR are safe and effective techniques. LVMR is associated with greater improvement in functional scores, while no statistically considerable difference in postoperative complications is observed between the groups, while LPMR offers a shorter operative duration. Given the low number of events, recurrence findings are interpreted as exploratory outcome. There is still a need for larger prospective studies.</p>","PeriodicalId":23391,"journal":{"name":"Updates in Surgery","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149246513","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}

Although several predictors of OLM, including tumor diameter, metabolic activity, molecular characteristics, and radiomics, have been extensively investigated, the predictive role of tumor volume remains poorly defined. This study aimed to evaluate whether tumor volume, quantified semi-automatically using artificial intelligence (AI)-assisted Synapse 3D software, could predict OLM in patients with clinically early-stage lung cancer. Patients who underwent surgical resection for clinically staged cT1b-cN0M0 lung cancer between 2018 and 2024 were included. Tumor volume was quantified using Synapse 3D software. Associations between tumor volume and OLM were assessed using univariable and multivariable logistic regression analyses. Because tumor diameter and tumor volume may introduce multicollinearity in multivariable models, separate receiver operating characteristic (ROC) curves were generated, and the corresponding areas under the curve (AUCs) were compared using the DeLong test. A total of 248 patients were included, of whom 59 (23.8%) were female. The mean age was 65.4 years. OLM were identified in 10.8%, 4.8%, and 2.0% of patients at the N1, N2a, and N2b nodal stations, respectively. Multivariable logistic regression identified younger age (p = 0.004), greater tumor volume (p = 0.01), and histopathological subtypes other than adenocarcinoma and squamous cell carcinoma as independent predictors of OLM. Tumor diameter, extent of resection, surgical approach, and PET-CT metabolic activity were not significantly associated with OLM. ROC analysis demonstrated that tumor volume had significantly greater discriminatory ability for predicting OLM than tumor diameter (AUC: 69% vs. 58%; DeLong test, p = 0.004).
