“…The documented increase in diagnostic yield after the introduction of the VCE in 2001, resulted in its rapid clinical acceptance for investigation of patients with recurrent gastrointestinal bleeding of obscure origin, primarily in those with negative small bowel barium enema studies (62), gastroscopy and colonoscopy (51). The inferior results achieved by radiology may be attributed to perceptional errors by the radiologist, or enterographic studies being technically suboptimal (63).…”

Capsule Enteroscopy and Radiology of the Small Intestine 2 ABSTRACT In a very few years, the video capsule for small bowel enteroscopy has gained widespread clinical acceptance. It is readily ingested, disposable, and allows for a complete, low-invasive endoscopic examination of the entire mucosa of the small bowel. It is a patient-friendly method and a first line procedure in the difficult evaluation of obscure gastrointestinal bleeding. It has the highest proven figure of diagnostic sensitivity for detecting lesions of the mucosa, irrespective of aetiology. The limitations of capsule endoscopy include difficulty in localizing mucosal lesions anatomically and its restricted use in patients with dysphagia, strictures or motor dysfunction. Strictures, transmural and extra-mural lesions in patients with small bowel Crohn's disease are evaluated by MRI-enterography and CT-enterography.Capsule Enteroscopy and Radiology of the Small Intestine 3 Imaging of the small bowel was, until recently, the responsibility of the radiologist, who, in dedicated centres, offered the patient not just a small-bowel follow-through with single exposures over time, but a dedicated, real time, fluoroscopic examination of a well distended small bowel, displayed in double-contrast and documented on spot films (1). This enteroclysis technique, well accepted by gastroenterologists, significantly improved both the detection of mucosal disease and the mapping of involved bowel segments. However, the duration of the examination, discomfort related to nasojejunal intubation and infusion of large volumes of contrast and distension materials, be it methyl cellulose or air (2), reduced general acceptance and dissemination of this method (3). VCE has evolved to be the first line procedure in many hospitals (7-13), keeping small bowel radiology as method of choice for patients who cannot take the capsule (13). In order to understand the diagnostic algorithm of modern small bowel examination we will discuss the video capsule technique, its indications and contraindications, advantages and disadvantages, types of true and false lesions and comparative studies of VCE and radiological methods of investigation of the small intestine. The video capsuleVCE was primarily developed for examination of small bowel mucosa (14,15). Rapid technical refinement has since resulted in a dedicated capsule for the oesophagus, and recently capsules for the study of both stomach and colon (16).The capsule measures 11 by 27mm and includes a light source and a camera inside a clear, transparent dome, batteries and a radio-transmitter (Figure 1). Whilst ushered forward by peristalsis the capsule transmits images continuously at two frames per second for around eight hours, a total of more than 60.000 images. The image has a 140° field of view, a focus depth of 1-30 mm, and an 8:1 magnification (17). An array of eight external detectors, applied to the abdominal wall, receives the images for storage in a solid state data recorder. Capsule Enteroscopy and Radiology of the Smal...

In the domain of gynecologic surgery an increasing number of surgeries are performed in a minimally invasive manner. These laparoscopic surgeries require specific psychomotor skills of the operating surgeon, which are difficult to learn and teach. This is the reason why an increasing number of surgeons promote checking video recordings of laparoscopic surgeries for the occurrence of technical errors with surgical actions. This manual surgical quality assessment (SQA) process, however, is very cumbersome and timeconsuming when carried out without any support from content-based video retrieval. Appl (2018) 77:16813-16832 Descriptor) that can be effectively used to find similar segments in a laparoscopic video database and thereby help surgeons to more quickly inspect other instances of a given error scene. We evaluate the retrieval performance of MIDD with surgical actions from gynecologic surgery in direct comparison to several other dynamic content descriptors. We show that the MIDD descriptor significantly outperforms the state-of-the-art in terms of retrieval performance as well as in terms of runtime performance. Additionally, we release the manually created video dataset of 16 classes of surgical actions from medical laparoscopy to the public, for further evaluations.

“…It should be noted that polyps selected for removal are of a large size, and those at high risk of ulceration, malignancy and intussusception. as these patients have more frequent intestinal polyps [19] . Moreover, polyps larger than 10 mm in diameter should be removed because of the risk of malignancy, either by DBE or intra-operative enteroscopy.…”

Despite significant advances over the last decade, mucosal lesions of the small bowel are poorly detected by imaging studies such as CT scan, MRI-enteroclysis and contrast-enhanced abdominal ultrasound. Capsule endoscopy (CE) has dramatically changed the diagnostic approach to intestinal diseases. Moreover, the use of CE can be extended to include other conditions. However, it is difficult to assess the positive influence of CE on patient outcomes in conditions involving a small number of patients, or in critically ill and difficult to examine patients. CE has the advantage of diagnosing intestinal lesions and of directing the use of double balloon enteroscopy (DBE) in order to obtain biopsy specimens. Moreover, CE allows repeated assessment in chronic conditions, especially to detect relapse of an infectious disease.

Abstract: Our results suggest that CE may be of clinical value in selected patients with FAP, whereas in PJS, CE could be used as first line surveillance procedure.
