Clinical Medicine Insights: Pathology, 2018 Perineurioma is a mesenchymal neoplasm best known in soft-tissue pathology. A colonic perineurioma is a relatively recently described entity and sometimes encountered in specimens from the large intestine, especially distal colon. Without its recognition, a perineurioma can be misdiagnosed as other more common gastrointestinal spindle cell neoplasms ...

Colonoscope tracking method based on shape estimation network [PDF]
Proceedings of SPIE Medical Imaging 2019: Image-Guided Procedures,
Robotic Interventions, and Modeling, Vol.10951, 109510Q, 2020 This paper presents a colonoscope tracking method utilizing a colon shape estimation method. CT colonography is used as a less-invasive colon diagnosis method. If colonic polyps or early-stage cancers are found, they are removed in a colonoscopic examination.

Colon capsule endoscopy for colonic surveillance [PDF]
Colorectal Disease, 2019 AbstractAimResources used in surveillance colonoscopies are taking up an increasing proportion of colonoscopy capacity. Colon capsule endoscopy (CCE) is a promising technique for noninvasive investigation of the colon. We aimed to investigate CCE as a possible filter in colonic surveillance with the primary outcome of reducing the number of ...

Machine learning-based colon deformation estimation method for colonoscope tracking [PDF]
SPIE Medical Imaging 2018: Image-Guided Procedures, Robotic
Interventions, and Modeling, 2018 This paper presents a colon deformation estimation method, which can be used to estimate colon deformations during colonoscope insertions. Colonoscope tracking or navigation system that navigates a physician to polyp positions during a colonoscope insertion is required to reduce complications such as colon perforation.

KST-Mixer: Kinematic Spatio-Temporal Data Mixer For Colon Shape Estimation [PDF]
Computer Methods in Biomechanics and Biomedical Engineering:
Imaging & Visualization, 2023, 2023 We propose a spatio-temporal mixing kinematic data estimation method to estimate the shape of the colon with deformations caused by colonoscope insertion. Endoscope tracking or a navigation system that navigates physicians to target positions is needed to reduce such complications as organ perforations.

Preventing parastomal hernias with systematic intraperitoneal specifically designed mesh
BMC Surgery, 2017 Background Parastomal hernia is a very common complication after stoma formation. Current surgical techniques for repairing parastomal hernia have unsatisfactory results. We aim to assess our preliminary experience with prophylactic mesh placement at the

Colonic tuberculosis masquerading as colon cancer [PDF]
Journal of Surgical Case Reports, 2012 Isolated colonic tuberculosis (TB) is rare, and the symptoms are nonspecific making early diagnosis and management difficult. Although colonoscopy and biopsy is an important diagnostic modality, the features are variable and the distinction from other conditions of the colon, especially Crohn's disease and cancer, may be impossible without surgical ...
