title: A trial of the use of patency capsules in combination with overnight capsule endoscopy.
abstract: BACKGROUND
  The PillCam® patency capsule (PPC) was developed to minimize the risk of capsule retention during capsule endoscopy (CE). Typically, the use of patency capsules prior to CE requires patients to be monitored over a period of time. To reduce the need for frequent outpatient visits during PPC examination and CE, we developed the overnight CE (ON-CE) procedure.
  
  
  METHODS
  Between October 2012 and January 2014, a total of 19 patients (15 males and 4 females, mean age 48.4 years) were administered PPC to assess the patency of the small intestine prior to ON-CE at JA Onomichi General Hospital in Hiroshima, Japan.
  
  
  RESULTS
  PPC confirmed patency of the small intestine in 15 of the 19 patients. Of these 15 patients, 14 proceeded to ON-CE. The CE was cancelled in 1 patient and the cecal intubation time exceeded 8 h in another patient. For the remaining 12 patients, the mean small intestine observation coverage was 92.3% and the mean cecal intubation time was 325 min. There were no adverse events and the discharge of the capsule was confirmed in all cases.
  
  
  CONCLUSIONS
  When patency of the gastrointestinal tract was confirmed with the PPC, ON-CE was performed safely and effectively.
