iatrogenic perforation of the colon during elective colonoscopy is a serious complication. surgical treatment remains the standard of care. we report a patient with a large colonic perforation that occurred during a screening colonoscopy, successfully repaired with laparoscopic methods. although the safety and efficacy of this approach is not entirely established, laparoscopy can be used to tre...

PURPOSE The aim of the study was to assess the use colonoscopy over time in the assessment of large bowel obstruction in a tertiary university hospital. METHODS Retrospective analysis of surgical and colonoscopy records for the years 1990-2009 in a university hospital. All patients diagnosed with non-conservatively managed bowel obstruction were included. RESULTS We recorded 644 patients di...

BACKGROUND The goal of this study is to examine utilization of early repeat colonoscopy ≤ 6 months after an index procedure. METHODS We identified persons having repeat colonoscopy ≤ 6 months following outpatient colonoscopy without prior colonoscopy ≤ 5 years or prior diagnosis of colorectal cancer (CRC). We modeled repeat colonoscopy using a generalized estimating equation with an exchangea...

A colonoscopy is performed to identify and/or correct suspected problems of the colon. The test enables a diagnosis to be made and specific treatment(s) suggested. Polyps or other lesions found during the exam may be removed or destroyed at that time, eliminating the need for a major operation later. If a bleeding site is identified, treatment can be administered to stop the bleeding. Other tre...

ulcerative colitis is associated with several malignancies. here we report one such association, a rare one, with papillary thyroid carcinoma, and discuss the possible risk factors of such an association.

BACKGROUND The appropriate interval between negative colonoscopy screenings is uncertain, but the numbers of advanced neoplasms 10 years after a negative result are generally low. We aimed to evaluate the cost-effectiveness of colorectal neoplasm screening and management based on repeat screening colonoscopy every 10 years or single colonoscopy, compared with no screening in the general populat...

Postpolypectomy surveillance has become a major indication for colonoscopy as a result of increased use of screening colonoscopy in Korea. In this report, a careful analytic approach was used to address all available evidences to delineate the predictors for advanced neoplasia at surveillance colonoscopy and we elucidated the high risk findings of the index colonoscopy as follows: 3 or more ade...

BACKGROUND Inadequate colonoscopy bowel preparation can lead to increased procedural time, decreased diagnostic yield, and an increased complication rate. Little is known about which patient characteristics may predict poor bowel preparation for routine, average-risk colonoscopy evaluation. METHODS 300 consecutive patients who underwent routine, average risk outpatient screening colonoscopy d...
