To compare the outcomes of patients who underwent autograft tenodesis with those who underwent allograft tenodesis for the treatment of chronic mechanical ankle instability. Ten patients who underwent allograft lateral tenodesis were compared with 15 patients who underwent lateral tenodesis using a split peroneus brevis tendon. Patients were followed up after an average time of 10.5 years. No statistically significant differences concerning American Orthopaedic Foot and Ankle Society and Karlsson-Peterson scores were reported (p = n.s.). A reduced average radiographic anterior talar translation was observed in the autograft group compared with the allograft group (1.4 and 4.0 mm respectively, p < 0.001). Both surgical techniques significantly improved subjective and objective outcomes in patients suffering from chronic ankle instability compared with pre-operatory status. Autograft stabilization provided reduced post-operative anterior talar translation compared with allograft tenodesis.

Background: Tumor size (TS) in pancreatic ductal adenocarcinoma (PDAC) is one of the most important prognostic factors. However, discrepancies between TS on preoperative images (TSi) and pathological specimens (TSp) have been reported. This study aims to evaluate the factors associated with the differences between TSi and TSp.

Background: As the population ages, the number of octogenarians with pancreatic ductal adenocarcinoma (PDAC) continues to rise. Morbidity and mortality following pancreatectomy have improved owing to safer surgery and better chemoradiation regimens. This study compares the outcomes and multimodality utilization in octogenarians (≥80 years) who underwent pancreaticoduodenectomy (PD) for PDAC, with a younger cohort.

Rising computed tomography (CT) workloads require more efficient image interpretation methods. Digitally reconstructed radiographs (DRRs), generated from CT data, may enhance workflow efficiency by enabling faster radiological assessments. Various techniques exist for generating DRRs.

Purpose: To investigate the effect of preoperative prealbumin levels on long-term survival outcomes after gastrectomy in patients with gastric cancer (GC) dichotomized based on age.

Methods: This retrospective cohort study included consecutive patients who underwent radical gastrectomy for primary stage I-III GC between May 2006 and March 2017. Patients were allocated to groups based on age (≥ 70 or < 70 years) and subgroups based on prealbumin levels (high, ≥ 22 mg/dL; moderate, 15-22 mg/dL; or low, < 15 mg/dL), and multivariate Cox regression was used for survival analyses.

Objective: To explore the efficacy and safety of the direct inferior endplate approach in percutaneous endoscopic interlaminar discectomy (PEID) for the treatment of L5-S1 disc herniation.

Methods: This was a retrospective analysis of 116 patients with L5-S1 disc herniation treated with PEID; 74 patients underwent surgery via the direct inferior endplate approach (group A), and 42 patients underwent surgery via the indirect approach (group B). The number of intraoperative fluoroscopy exposures, establishment channel time, operation time, postoperative visual analogue scale (VAS) score, and Oswestry Disability Index (ODI) were compared between the 2 groups.
