Abstract
AIM : The aim of this study was to compare the estimated distance using capsule endoscopy (CE) with measurements taken with double balloon endoscopy (DBE) .
Patients and Methods : This study targeted 15 patients with small bowel tumor who underwent CE and DBE. The estimated distance defined as PD and TD. PD is defined as the value of calculating as “P×small bowel length (SBL) ”. P is %Viewing progress (%Capsule Progress) (%) that may indicate where CE moved from the duodenum by using RAPID software in the v6.5 (v8) . TD is defined as the value of calculating as “T×SBL”. T is the %Time (%SB time) (%) that may indicate when CE moved from the duodenum by using this software. These TD and PD values were compared with measurements taken with DBE (DBE) . SLB was determined as 9m by the coefficient of determination between TD, PD and DBE.
Results : Mean values for TD, PD, and DBE were 298.1±266.9, 345.0±309.4 and 378.1±346.8 cm respectively, indicating no significant difference between the three groups (P=0.777) . The correlation coefficient between TD and DBE was 0.912, and the coefficient between PD and DBE was 0.965 (P<0.01) .
Conclusions : The estimated distance exhibited strong correlative relationships with the measurements and may be useful for performing DBE.
