BACKGROUND In the management of large bowel obstruction, on-table lavage and intraoperative colonoscopy allow a safe resection and primary anastomosis in selected patients. Previous techniques carry serious disadvantages, in the form of inconvenient drainage route and spillage. A novel technique of in-sleeve on-table colonic lavage using a camera sleeve is described. METHODS Six patients (58-...

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...

Colonic perforation occurs in a variety of clinical scenarios and colonoscopy-associated perforation is one of the important reasons for colonic perforation. Colonoscopy-associated perforation may be diagnosed during colonoscopy procedure by the visualization of evident colonic wall defect or, after the completion of colonoscopy, by the visualization of leaked air in the peritoneal or retroperi...

BACKGROUND Many factors have been found to affect the difficulty of colonoscope insertion, such as age, gender, body mass index (BMI), history of abdominal surgery and operator etc. However, a scoring system may be more useful to predict the difficulty during colonoscopy. METHODS The individual and procedure-related data of 616 patients undergoing colonoscopy were prospectively collected from...

AIM Colonoscopy has become accepted as the most effective method for colon exploration. Some application problems have been detected in the setting of normal clinical care due to its wide range of uses in recent years, and therefore there is a need to measure colonoscopy quality. For that purpose valid quality indicators are necessary to be defined. The application process of some quality indic...

INTRODUCTION Narrow‑band imaging (NBI) is a new, promising technique that might be helpful in the detection of colorectal polyps during colonoscopy. OBJECTIVES The aim of the study was to compare the usefulness of NBI with white‑light endoscopy (WLE) for the detection of polyps as well as to determine the distribution of missed polyps. PATIENTS AND METHODS This was a randomized controlled t...

INTRODUCTION insufflation with carbon dioxide (CO2) during endoscopies compared to air is associated with a decrease in abdominal discomfort after the examination, because CO2 is readily absorbed through the small intestine and eliminated by the lungs. AIM the objective of this randomized clinical trial was to assess the effect of CO2 insufflation on pain and abdominal distension after an ile...

AIM The aim of this study is to evaluate the usefulness of the fecal immunochemical test (FIT) in colorectal cancer screening, detection of precancerous lesions and early colorectal cancer. MATERIAL AND METHODS The study evaluated asymptomatic patients with average risk (no personal or family antecedents of polyps or colorectal cancer), aged between 50 and 74 years. The presence of the occult...

Screening Colonoscopy A screening colonoscopy is done to check for cancer and inflammatory diseases like ulcerative colitis. Most colorectal cancers (CRC) start as non-cancerous polyps (tiny, fast growing cells that may become cancer). Removing polyps or finding cancer at an early stage can increase your chances for a full recovery.2 During the colonoscopy, polyps can be removed with tiny instr...
