Small bowel cleanliness in capsule endoscopy: a case–control study using validated artificial intelligence algorithm

Abstract

Small bowel capsule endoscopy (SBCE) may need to be performed immediately after colonoscopy without additional bowel preparation if active small bowel diseases are suspected. However, it is unclear whether the small bowel cleanliness is adequately maintained even after SBCE is performed immediately after colonoscopy. We compared the small bowel cleanliness scores of the study group (SBCE immediately after colonoscopy) and control group (SBCE alone) using a validated artificial intelligence (AI) algorithm (cut-off score > 3.25 for adequate). Cases of SBCE in which polyethylene glycol was used were included retrospectively. Among 85 enrolled cases, 50 cases (58.8%) were the study group. The mean time from the last dose of purgative administration to SBCE was 6.86 ± 0.94 h in the study group and 3.00 ± 0.18 h in the control group. Seventy-five cases (88.2%) were adequate small bowel cleanliness, which was not different between the two groups. The mean small bowel cleanliness score for the study group was 3.970 ± 0.603, and for the control group was 3.937 ± 0.428. In the study group, better colon preparation resulted in a higher small bowel cleanliness score (p = 0.015). Small bowel cleanliness was also adequately maintained in SBCE immediately after colonoscopy. There was no difference between the time and volume of purgative administration and small bowel cleanliness.

The role of video capsule endoscopy in the diagnosis of gastrointestinal diseases: experience of the Department of Diagnostic and Operative Endoscopy

“…Качественная эндоскопическая диагностика невозможна без хорошей подготовки, в особенности осмотр тонкой кишки при помощи видеокапсулы, когда нет возможности выполнить отмывание и аспирацию кишечного содержимого. На сегодняшний день проводится множество исследований, изучаю щих различные по длительности периоды белковой диеты или голодания, а также схемы приема препаратов подготовки [15,16]. Схема, назначаемая нашим пациентам (2-3-дневный белковый рацион питания, 2-этапная схема препарата на основе ПЭГ, прием пеногасителя накануне и в день исследования), позволила добиться хорошей и отличной подготовки тонкой кишки в 95% случаев.…”
