High Index Of Suspicion

This article describes two cases of juxta-articular osteoid osteoma of talar neck. Both patients were initially treated as having ankle sprains or arthritis before diagnosis of osteoid osteoma. A high index of suspicion and appropriate imaging studies are important to make an early diagnosis of this disorder. Once diagnosis is confirmed, en bloc resection and autogenous bone graft can cure the disorder.

Arthroscopic Removal

We report a case of a subperiosteal osteoid osteoma on the talar neck that was removed arthroscopically. Intralesional excision, en bloc resection, and percutaneous ablation techniques have all been used for the treatment of osteoid osteoma. For intra-articular osteoid osteomas, arthroscopy-assisted removal of the tumor has been described in a few case reports. Obtaining a nidus fragment for pathologic evaluation is important during arthroscopic removal of intra-articular osteoid osteomas. Sometimes it is not possible to obtain a specimen for pathologic examination. In the present case, the osteoid osteoma on the talar neck was easily located, the nidus was completely removed, and the tumor was extirpated. (J Am Podiatr Med Assoc 97(3): 238–243, 2007)

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.

Colorectal Endoscopic Submucosal Dissection

Abstract Background and study aims The pocket-creation method (PCM) facilitates dissection of the central part of a tumor. We previously developed the PCM with clip traction (PCM-CT) to facilitate opening the mucosal pocket, which otherwise could become cumbersome. In the present study, we aimed to examine the feasibility of PCM-CT for colorectal endoscopic submucosal dissection (ESD). Patients and methods PCM-CT was performed on 30 patients with early colorectal tumors from October 2019 to April 2020. PCM-CT allows efficient opening of the mucosal pocket by using the PCM to dissect the center of the lesion and then apply traction with a single clip after making a circumferential mucosal incision. Results The median specimen major axis length, ESD time, ESD speed, and en bloc resection rate were 48 mm, 84 minutes, 20 mm2/min, and 100 % (30/30), respectively. The success rates for the traction clip and median single-clip-traction time were 100 % (30/30) and 1.5 minutes, respectively. Conclusions Colorectal ESD using PCM-CT is a simple and promising method.
