Abdominal surgery affects small bowel transit time and completeness of capsule endoscopy.
The aim of the study was to evaluate bowel dysmotility in patients with a history of abdominal surgery by measuring both gastric transit time and small bowel transit time during capsule endoscopy and assessing the completeness of the examination. The study included 26 patients who had undergone abdominal surgery (postoperative group) and 52 patients who had not (control group). The capsule reached the cecum in 50.0% of the postoperative group and 80.8% of the control group (P=0.005). While there was no significant difference in gastric transit time between the two groups (P=0.882), small bowel transit time was significantly longer in the postoperative group (338.3+/-119.2 min) than in the control group (266.4+/-110.8 min, P=0.010). This is the first study to report that the small bowel transit time during capsule endoscopy is prolonged in patients who had a history of abdominal surgery, resulting in a lower frequency of complete examination.
