Background. Endoscopic laser-ablative therapy of upper tract urothelial carcinoma offers kidney-sparing treatment for well-selected low-risk tumors. The traditional technique consists of tumor biopsy with flexible forceps or nitinol basket for pathologic assessment of stage and grade, followed by laser ablation of the tumor. In this case, we present the use of the new T-1470 LiteTouch™ laser for intraoperative tumor en bloc resection, affording both tissue acquisition and tumor ablation. Case Presentation. An 81-year-old female with a past medical history significant for stage 4 chronic kidney disease, peripheral artery disease, coronary artery disease, type 2 diabetes mellitus, and gout was diagnosed with a 2 cm left upper tract high-grade papillary urothelial carcinoma confirmed by cytology with cell block preparation. Using a novel approach, the tumor was resected, en bloc, using the T-1470 LiteTouch™ laser which allowed for sufficient tissue resection for pathologic examination and strong hemostasis. This new technique is the first recorded example of tumor en bloc resection using the T-1470 LiteTouch™ laser of an upper tract urothelial carcinoma. Conclusion. The use of the T-1470 LiteTouch™ laser offers promise for its use as a novel laser for the endoscopic treatment of upper tract urothelial carcinoma. It shows potential for advantages over current techniques through its ability to achieve en bloc resection and superior hemostasis.

Metastatic Osteosarcoma

To obtain a wide resection and safe margins in recurrent spine osteosarcoma, the surgical approach can include – posterior only, combined posterior and anterior, and combined posterior and anterior with a return to posterior in multiple stages. In our case, we used a novel approach of multiple extensile exposures circumferentially in a single stage with a single surgical prep. We present the case of a 9-year-old female with a history of metastatic osteosarcoma, who previously underwent an attempted en bloc resection with an L3 corpectomy and left below knee amputation. At 1 year follow-up, she developed a recurrent solitary spine lesion at the previous surgical resection site. An additional attempt at complete surgical resection was performed with a complex en bloc L2, L3, L4 corpectomy with removal of deep spinal implants and anterior and posterior spinal fusion with instrumentation and revision decompressive laminectomy. The patient had a good functional outcome without neurological deficits, except those resulting from resection of involved lumbar nerve roots. At last follow-up of 5 months, there was no local recurrence or distant metastasis. This approach for revision resection of recurrent spinal osteosarcoma can be performed successfully with clean margins in a safe manner.

Abstract Background and study aims Adequate mucosal elevation by submucosal injection is crucial for patient safety and efficiency during endoscopic submucosal dissection (ESD). This study aimed to evaluate the efficacy of fibrin glue (FG) as a long-lasting submucosal injection agent and to evaluate the technical feasibility of FG injection for ESD. Materials and methods To compare the capabilities of different agents in maintaining submucosal evaluation, we injected FG, hyaluronic acid solution, and normal saline into the porcine gastric specimen that was incised into approximately 5 × 5 cm squares. Then, we measured the height of submucosal elevations over time. Moreover, three hypothetical lesions from the resected porcine stomach underwent ESD with FG injection. Thereafter, we conducted macroscopic and histopathologic analyses. Results FG maintained the greatest submucosal elevation among all the injection agents. Three ESD procedures were performed with en bloc resection. Both macroscopic and histopathologic findings showed a thick FG clot on the ulcers. Conclusions The FG solution can be potentially used as an ESD submucosal injection agent in an in vitro model.
