Abstract

Video-capsule endoscopy gastric transit time was significantly longer in diabetes mellitus patients (87 minutes) compared to non-diabetic patients (24 minutes).

The caecum was visualized in 69% of diabetes mellitus patients, compared to 89.6% of non-diabetic controls.
In patients where the caecum was reached, small bowel transit time was shorter for diabetes mellitus patients (261.2 minutes) than for non-diabetic controls (302 minutes).
Prolonged gastric transit time may contribute to incomplete examinations in video-capsule endoscopy for diabetes mellitus patients.
Further prospective studies are needed to enhance understanding of video-capsule endoscopy transit times in diabetes mellitus.

BACKGROUND: Small intestine video-capsule endoscopy examination in patients with diabetes mellitus may be incomplete due to delayed gastric emptying.

AIM: To measure video-capsule endoscopy gastric and small bowel transit time and to assess the completeness of the examination in diabetes mellitus patients.

METHODS: In this retrospective, case-control study, we examined capsule endoscopy videos from 29 consecutive diabetes mellitus patients. Fifty-eight matched for sex, type of preparation, age and reason for referral non-diabetic controls were selected from our video-capsule endoscopy database. Two independent experienced investigators measured transit times and assessed examinations' completeness.

RESULTS: Video-capsule endoscopy gastric transit time was significantly longer in diabetes mellitus (87, 1-478 min) compared to non-diabetic patients (24, 4-108 min, p<0.001). The caecum was visualized in 20/29 (69%) diabetes mellitus and 52/58 (89.6%) non-diabetic controls (p=0.02). In 16 diabetes mellitus patients that video-capsule endoscopy reached the caecum, small bowel transit time was significantly shorter (261.2+/-55.5 min) compared to their 32 non-diabetic matched controls (302+/-62.7 min, p=0.03).

CONCLUSIONS: Patients with type 2 diabetes mellitus have prolonged video-capsule endoscopy gastric transit time compared to non-diabetic patients. Prospective studies are required to complete our understanding of video-capsule endoscopy transit times in the setting of diabetes mellitus.
