PTU-127 Poor quality of capsule endoscopy images has negative effect on diagnosis of small bowel malignancy

AbstractChilling and freezing injuries of olives harvested in geographically high elevated locations may affect the quality of olive, and subsequently lead to oil with a poor quality. This study was aiming to investigate the influence of whether changes and freezing condition on the quality of extracted olive oil. The olive Koroneiki cultivar obtained from two origins was stored at three different temperatures (20, 5 and −18 °C) before oil extraction and common analyses (oil yield, acidity, peroxide value, thiobarbitorik acid value, total phenolics level, and color) were carried out in different time intervals (0, 20, 40, and 60 days) in order to assess the olive oil quality. Our data revealed that longer storage times significantly (P < 0.05) decreased the quality of olive oil. The fruits remained at 20 °C provided the lowest oil quality in all parameters. For example, the acidity of olive oil at 20 °C was 177% higher than samples kept at 5 °C after 20 days of olive storage. The general trend for comparing the quality parameters of extracted oils from olives kept at different temperatures was −18 > 5 > 20 °C. No significant negative effect (P < 0.05) was found for the samples kept at −18 °C, compared to 5 °C. Also, the geographical source of olive had a statistically significant influence (P < 0.05) on the quality of olive oil.

Small Bowel Malignancy

Abstract Background and study aims Small bowel cancer is rare, accounting for < 5 % of all gastrointestinal neoplasms. Capsule endoscopy has become the procedure of choice for non-invasive diagnosis of small bowel diseases. Data on capsule endoscopy diagnosis of small bowel cancer are limited. The objective of the study was to determine the frequency, indications and diagnostic work-up of patients with small bowel malignancy found by capsule endoscopy at a Scottish tertiary center. Patients and methods In this retrospective study, records all patients who underwent small bowel capsule endoscopy at our center over a 10-year period were reviewed for possible malignancy. Further data were gathered on preceding and subsequent investigations, management and outcome of these patients. Results From 1949 studies, small bowel malignancies were diagnosed in only 7 patients (0.36 %; 2F/5M; median age 50, range 34 – 67). The main indication was iron-deficiency anemia (n = 5). Prior to capsule endoscopy, 6 of 7 patients had bidirectional endoscopies and one had gastroscopy. All prior investigations were normal or nondiagnostic. Two of 7 experienced capsule retention. Five of 7 underwent surgery. Four patients died, giving a 5-year survival rate of 42.9 %. Conclusion Small bowel malignancies diagnosed by capsule endoscopy are rare, and the median age of 50 indicates they are more common in relatively younger patients. Capsule endoscopy is effective at diagnosing a rare malignancy when other imaging modalities have failed.

Bowel Cleansing

AbstractCapsule Enteroscopy (CE) is a fundamentally new method in diagnostic endoscopy. However, there are several factors influencing the quality of this procedure, including impermeable fluids, food remains etc. The aim of the study was to assess one of the most popular currently used bowel preparation methods and evaluate possible effects of various factors. 136 CE examinations were analysed. Each patient was prepared using 2 litres of polyethylene glycol (PEG) one day prior to examination. There was a special form filled in for each patient, which included relevant parameters (anamnesis, CE data etc.). Of 136 CE cases, 84 (61.8%) were female patients and 52 (38.2%) were male. The small bowel (SB) transit time in 112 patients varied from 39 to 502 minutes, but in 24 cases the capsule did not reach caecum. The degree of bowel cleanliness was as follows: very good — 30 (22.1%) patients, satisfactory — 97 (71.3%), and poor — 9 (6.6%). A positive correlation was observed between the degree of SB cleanliness and the SB transit time (p = 0.015). A longer SB transits time was associated with poor SB cleanliness. The results obtained in this study showed that the quality of SB cleanliness is affected by SB transit time. A relatively large percentage of cases rated as satisfactory bowel cleanliness and comparatively small percentage of bowel cleanliness cases rated as “very good” were observed when 2 litres of PEG were used prior to CE, indicating an important issues in preparation of the bowel prior to CE.

The Ideal

Video capsule endoscopy that was launched 10 years ago has become a first-line procedure for examining the small bowel. The most common indications for capsule endoscopy are obscure gastrointestinal bleeding, Crohn's disease, polyposis syndromes, and evaluation of patients with complicated celiac disease. The ideal capsule should improve the quality of the image and have a faster frame rate than the currently available one. There should be a therapeutic capsule capable of performing a biopsy, aspirating fluid, delivering drugs, and measuring the motility of the small bowel wall. Another major leap forward would be the capability of remote control of capsule's movement in order to navigate it to reach designated anatomical areas for carrying out a variety of therapeutic options. Technology for improving the capability of the future generation capsules almost within grasp and it would not be surprising to witness the realization of these giant steps within the coming decade. In this review we will focus on the current clinical applications of capsule endoscopy for imaging of the small bowel and colon and will additionally give an outlook on future concepts and developments of capsule endoscopy.
