Background/aims: We investigated the clinical practice patterns of Korean endoscopists for the endoscopic resection of colorectal polyps.
Methods: From September to November 2021, an online survey was conducted regarding the preferred resection methods for colorectal polyps, and responses were compared with the international guidelines.
Results: Among 246 respondents, those with <4 years, 4-9 years, and ≥10 years of experience in colonoscopy practices accounted for 25.
Article Synopsis
- The study explored early- and late-onset cholecystitis in patients who underwent Y-configured metal stent placement for malignant hilar obstruction from June 2005 to August 2020, with 109 participants included.
- Key risk factors for early-onset cholecystitis identified were diabetes, the length of the Y-stent's common part, gallbladder contrast filling during the procedure, and tumor invasion of the cystic duct.
- For late-onset cholecystitis, significant risk factors were stent obstruction and repeated endoscopic procedures, with multivariate analysis confirming the length of the stent's common part for early-onset and stent obstruction for late-onset cases.
Background: The unconstrained master devices have emerged as attractive alternatives to the existing linkage-based counterparts. However, the conventional unconstrained master device's manipulation methods have several disadvantages in efficiency and precision.
Methods: We propose an encountered-type master device based on an electromagnetic tracking solution with a prismatic joint at the tip, capable of continuous spatial manipulation with the tip supported on the surface.
OBJECT The progression of cervical ossification of the posterior longitudinal ligament (OPLL) can lead to increase in the size of the OPLL mass and aggravation of neurological symptoms. In the present study, the authors aimed to analyze the progression of cervical OPLL by using CT imaging, elucidate the morphology of OPLL masses, and evaluate the factors associated with the progression of cervical OPLL. METHODS Sixty patients with cervical OPLL were included.

Material And Methods: A total of 130 patients who underwent anterior decompression and fusion for degenerative cervical spine disease with a follow-up of at least 1 year were analyzed retrospectively. The cases were divided into three groups: autograft and plate (38 cases, group A), allograft and plate (44 cases, group B), and Zero-P (48 cases, group C).
This report describes a rare clinical entity, thoracic myelopathy due to ossification of the posterior longitudinal ligament (OPLL), and its management. A 40-year-old woman presented with thoracic myelopathy due to OPLL, extending from T2-T9. We performed a posterior laminectomy and instrumented fusion.

Methods: A total of 155 patients who underwent ACDF with more than 1 year follow up were included. Radiologically, IVH and interfacet distance (IFD) of the operated segment were measured preoperatively and postoperatively.
