Development and validation of the SIMPLE endoscopic classification of diminutive and small colorectal polyps
2018
Abstract Background Prediction of histology of small polyps facilitates colonoscopic treatment. The aims of this study were: 1) to develop a simplified polyp classification, 2) to evaluate its performance in predicting polyp histology, and 3) to evaluate the reproducibility of the classification by trainees using multiplatform endoscopic systems. Methods In phase 1, a new simplified endoscopic classification for polyps – Simplified Identification Method for Polyp Labeling during Endoscopy (SIMPLE) – was created, using the new I-SCAN OE system (Pentax, Tokyo, Japan), by eight international experts. In phase 2, the accuracy, level of confidence, and interobserver agreement to predict polyp hi…
Abdominal scintigraphy for diagnosis of intestinal bleeding
1978
Abdominal scintigraphy with99mTc-pertechnetate, using a gamma-camera linked to a data processor, was done in 8 patients with acute massive intestinal hemorrhage and in 34 patients with chronic recurrent intestinal hemorrhage. Endoscopy and x-ray studies had failed in all patients to reveal a bleeding source. All but 3 patients underwent exploratory laparotomy, confirming the abnormal findings of scintigraphy. In all acutely bleeding patients, scintigraphy was positive. The bleeding was proven by laparotomy to be due to Meckel's diverticulum with gastric mucosa in 5, jejunal neurinoma in 1, and sigmoid colon carcinoma in 1 patient. Scintigraphy was positive in only 3 chronically bleeding pat…
Push-and-pull enteroscopy using a single-balloon technique for difficult colonoscopy.
2006
Background and study aims Several factors predict difficult or incomplete colonoscopy with a standard colonoscope, including female gender, low body mass index, extensive diverticulosis, and prior pelvic surgery. Patients and methods A push-and-pull enteroscopy device and a single-balloon technique was used in 14 patients (six men, eight women; mean age 62 +/- 15 years) after failure of ileocolonoscopy or endoscopic therapy using either a standard or a pediatric colonoscope. The original ileocolonoscopy had been performed to investigate colon polyps (n = 6), an obscure inflammatory process in the ileocecal region (n = 6), or iron deficiency anemia with a positive fecal occult stool test (n …
Review article: in vivo imaging by endocytoscopy
2011
Aliment Pharmacol Ther 2011; 33: 1183–1193 Summary Background Endocytoscopy (EC) enables in vivo microscopic imaging at 1400-fold magnification, thereby allowing the analysis of mucosal structures at the cellular level. In contrast to fluorescence imaging with confocal laser endomicroscopy which allows analysis of mucosal structures up to 250 μm in depth, EC is based on the principle of contact light microscopy and only allows visualisation of the very superficial mucosal layer. Aim To systematically review the feasibility and diagnostic yield of EC for in vivo diagnosis of diseases. Methods A systematic search of the literature on diagnostic interventions in the gastrointestinal tract u…
Preparation for Endoscopic Examination
1979
Inspection of the perianal area, the digital rectal examination, and the proctoscopic examination may be done without special preparation.
Indications for Performing a Proctologic Examination and Endoscopy
1979
Complaints from the patient about discomfort in the anal region, rectal bleeding, and change in bowel habits — especially recent occurrence of constipation or diarrhea or a change in either symptom — as well as tenesmus are obligatory reasons for conducting a proctologic examination. These symptoms should never be ignored or treated by prescription of hemorrhoid suppositories, antispasmodics, analgesics, or laxatives.
Panintestinal capsule endoscopy in patients with celiac disease
2021
INTRODUCTION Capsule endoscopy has proven its utility in diagnosing villous atrophy and lymphoma in patients with celiac disease. Recently, a novel capsule endoscopy system was introduced which enables the examination of the small and large bowel. So far, it has not been evaluated in patients with celiac disease. OBJECTIVE The primary objective of this study was to evaluate the novel panintestinal capsule endoscopy system in patients with celiac disease. METHODS Eleven patients with histologically proven celiac disease (Marsh 0-IV), who underwent a panintestinal capsule endoscopy between March 2018 and April 2019 at our institution, were included in this retrospective single-center study. A…
