In order to determine the relative yields of colonoscopic and radiologic examinations of the colon, the following guidelines are suggested: (a) prospective data collection; (b) a standard, effective colon cleansing regimen; (c) colonoscopic and radiologic examiners of comparable expertise; (d) examiners should be unaware of each other's findings; (e) a suitable method for demonstrating false-negative findings and for resolving conflicting findings between the two examinations; and (f) indexing of the study findings as to lesion size, lesion location, quality of colon cleansing, and examiner's level of confidence. The two examinations should be used as complementary diagnostic procedures.

Objectives: Colonic manometry catheter placement can be performed by colonoscopy or fluoroscopy. Our objective was to compare outcomes of colonoscopic to fluoroscopic catheter placement in children based on the extent of colon study and the likelihood of catheter displacement.
Methods: Colonic manometry studies performed between May 2015 and May 2022 were reviewed.

Standard-of-care (SoC) imaging for assessing colorectal polyps during colonoscopy, based on white-light colonoscopy (WLC) and narrow-band imaging (NBI), does not have sufficient accuracy to assess the invasion depth of complex polyps non-invasively during colonoscopy. We aimed to evaluate the feasibility of a custom endoscopic optical coherence tomography (OCT) probe for assessing colorectal polyps during routine colonoscopy. Patients referred for endoscopic treatment of large colorectal polyps were enrolled in this pilot clinical study, which used a side-viewing OCT catheter developed for use with an adult colonoscope.

Postpolypectomy syndrome (PPS), also known as postpolypectomy coagulation syndrome or transmural burn syndrome, is a rare complication following colonic polypectomy characterized by abdominal pain, fever, and leukocytosis. Herein, we present a case of a patient in his 70s who developed abdominal pain and fever after a polypectomy. He was diagnosed with PPS, which rapidly progressed to septic shock necessitating left hemicolectomy.

Objectives: To compare the value of tumor stroma ratio (TSR) and radiomic signature from baseline MRI for stratifying the risk of distant metastases (DM) in patients with locally advanced rectal cancer (LARC).
Materials And Methods: Data from 302 patients with LARC who underwent neoadjuvant chemoradiotherapy and total mesorectal excision in our hospital between 2015 and 2018 were retrospectively reviewed, and the patients were randomly allocated into the training and validation cohorts in a ratio of 7:3. Patients were followed-up for more than 3 years postoperatively with metachronous DM as the endpoint.
