  • 简介:摘要Endoscopic ultrasound (EUS) has both diagnostic and therapeutic clinical applications. This review article focuses on recent advances in two commonly performed procedures: EUS-guided tissue acquisition and EUS-guided drainage. There is a shift from acquiring aspirates for cytology to obtaining tissue cores for histological diagnoses and molecular analyses. There is growing interest and research about artificial intelligence in EUS. Artificial intelligence may potentially be useful to guide clinical decision making if biopsy results are non-diagnostic. The range of EUS-guided drainage procedures has expanded. EUS-guided drainage of walled-off pancreatic fluid collections is an accepted first line treatment option. EUS-guided palliative drainage of malignant biliary obstruction after unsuccessful endoscopic retrograde cholangiopancreatography (ERCP) is now an accepted alternative to percutaneous transhepatic biliary drainage. EUS-guided gallbladder drainage for management of acute cholecystitis is now a preferred option over percutaneous cholecystostomy for non-surgical candidates. Other EUS-created gastrointestinal anastomoses such as EUS-guided gastroenterostomy in the context of gastric outlet obstruction, and EUS-directed transgastric ERCP for Roux-en-Y gastric bypass are now technically feasible, but further prospective randomized studies are needed to establish the actual clinical impact.

  • 简介:AbstractPurpose:Treatment of irreducible femoral intertrochanteric fractures often requires open reduction. However, the technique unavoidably causes patients to suffer greater trauma. As such, minimally invasive techniques should be employed to reduce the surgical-related trauma on these patients and maintain a stable reduction of the fractures. Herein, a minimally invasive wire introducer was designed and used for the treatment of femoral intertrochanteric fractures. The effectiveness of using a wire-guided device to treat irreducible femoral intertrochanteric fractures was evaluated.Methods:Between 2013 and 2018, patients with femoral intertrochanteric fractures who were initially treated by intramedullary nail fixation but had difficult reduction using the traction beds were retrospectively reviewed. Decision for an additional surgery was based on the displacement of the fracture. The patients were then divided into two groups: those in the control group received an open reduction surgery while those in the observation group received a closed reduction surgery using a minimally invasive wire introducer to guide the wire that could assist in fracture reduction. The operation time, blood loss, visual analogue scale scores, angulation, reduction, neck-shaft angle, re-displacement, limb length discrepancy, and union time were then recorded and analyzed to determine the efficiency of the wire introducer technique. Categorical variables were analyzed by using Chi-square test, while continuous variables by independent t-test and the Mann-Whitney test accordingly.Results:There were 92 patients included in this study: 61 in the control group and 31 in the observation group. There were no significant differences in baseline demographic factors between the two groups. All surgeries were successful with no deaths within the perioperative period. The average follow-up time for the patients was 23.8 months. However, the observation group had a significantly shorter operation time, lower visual analogue scale score, less intraoperative bleeding, and shorter fracture healing time. There were no significant differences in the angulation, reduction, neck-shaft angle, and limb length discrepancy between the two groups.Conclusion:The minimally invasive wire guide achieved a similar effect to that of open reduction in the treatment of intertrochanteric fractures with difficult reduction. Moreover, the minimally invasive wire introducer is a good technology that accurately guides the wire during reduction. Indeed, it is an effective technique and achieves good clinical outcomes in restoration of irreducible femoral intertrochanteric fractures.

  • 简介:AbstractObjective:Immunotherapy is an effective tumor treatment strategy. However, its long treatment cycle limits its wide application across all cancer types. In this study, we optimized upconversion nanoparticles and manganese composite particles with a porous structure as a nanoplatform for synergistic photodynamic therapy (PDT) and photothermal therapy (PTT), and subsequent longer-term immunotherapy.Methods:The morphology, phase, and stability were first characterized to evaluate the biocompatibility of this material. The upconversion and near infrared II luminescence properties of the material and its stimuli-response effect were assessed from the absorbance and photoluminescence spectra. Phototherapy including PDT and PTT was demonstrated in vitro and in vivo, and immunotherapy was used to enhance the phototherapy. This study was approved by the Xi’an Jiaotong University, China (approval No. XJTULAC2020-585) on April 2, 2020.Results:The nanoplatform showed good PDT and PTT effects with high upconversion luminescence, and exhibited a more sensitive glutathione response (detection limit: 55 μg/mL) using fluorescence recovery than that based on absorbance recovery, with the detection range extending up to 1.2 mg/mL. When the surface of the composite particles was modified with an anti-PD-L1 immune checkpoint inhibitor, it targeted A549 lung cancer cells. The resulting immune response enhanced the long-term anti-tumor effect of the therapy, especially in lung cancer patients with high PD-L1 expression.Conclusion:The designed composite can be simultaneously used to detect the glutathione concentration based on luminescence recovery in the tumor cells and as a theranostic nanoplatform for synergistic immuno-phototherapy when combined with an antibody.
