Abstract Background Gastrointestinal vascular malformations are rare benign neoplasms of the gastrointestinal tract, with rectosigmoid region being most frequently involved site. Patients often manifest recurrent, intermittent rectal bleeding, which might occasionally be life-threatening. Case presentation A 39-year-old man a history hemorrhoid operations twice was presented to our gastroentero...

OBJECTIVE We aimed to determine the efficacy and safety of early (within the first 24 hour from application) endoscopy and colonoscopy in very elderly patients with GIS bleeding. METHODS In this study, 95 patients were included who underwent early endoscopy with the pre-diagnosis of upper GIS bleeding or endoscopy-colonoscopy with the pre-diagnosis of lower GIS bleeding between 2012 and 2016....

Background: Acute appendicitis after colonoscopy is a rare sequela and may be incidental or a true complication of colonoscopy. This review explores the cause and effect relationships between colonoscopy and the development of acute appendicitis. Methods: We conducted a systematic review of the literature to identify articles up to July 2011. The following time intervals were collated from docu...

background: to perform screening for colonic cancer and to diagnose other colic diseases, colonoscopies are required. comfort of patient during colonoscopy is very important. currently, there are two types of sedation used during colonoscopy-the general anesthesia and sedoanalgesia. sedo-analgesia is the most frequently used type of sedation employed during colonoscopy worldwide. materials and ...

BACKGROUND Colonoscopy is used for early detection and prevention of colorectal cancer, but evidence on the magnitude of overall protection and protection according to anatomical site through colonoscopy performed in the community setting is sparse. We assessed whether receiving a colonoscopy in the preceding 10-year period, compared with no colonoscopy, was associated with prevalence of advanc...

Background: Appropriate management of lower-GI hemorrhage remains controversial largely because outcomes data are lacking. It is our hypothesis that clinical factors, such as comorbidity, hemodynamic instability, and timing of colonoscopy, are associated with hospital lengths of stay. Methods: Medical records of patients hospitalized for lower-GI hemorrhage from 1993 to 2000 were reviewed and a...

BACKGROUND Fecal occult blood testing (FOBT) can be adapted to a limited colonoscopy capacity by narrowing the age range or extending the screening interval, by using a more specific test or hemoglobin cutoff level for referral to colonoscopy, and by restricting surveillance colonoscopy. Which of these options is most clinically effective and cost-effective has yet to be established. METHODS ...

Formal colonoscopy training requires a significant amount of time and effort. In particular, it requires actual patients for a realistic learning experience. The quality of colonoscopy training varies, and includes didactic courses and procedures proctored by skilled surgeons. A colonoscopy training model is occasionally used as part of the training method, but the effects are minute due to bot...

The effect of non-alcoholic fatty liver disease (NAFLD) on the occurrences of colorectal neoplasm (CRN) at surveillance colonoscopy is rarely evaluated. We retrospectively reviewed medical records of 1,023 patients who had both index and surveillance colonoscopy at a single institution. The cumulative occurrence rates of overall and advanced CRN at the time of surveillance colonoscopy were comp...

BACKGROUND There have been many reports about a variety of factors associated with incomplete colonoscopy or difficult colonoscopy with long cecal intubation time (CIT). The aim of this retrospective study was to analyze the factors related to difficult colonoscopy under conscious sedation and demonstrate the clinical utility of a small-caliber scope as rescue by using the data from a large num...
