Assessment of Capsule Endoscopy Utilizing Capsocam Plus in Patients With Suspected Small Bowel Disease Including Pilot Study With Remote Access Patients During Pandemic

BACKGROUND: CapsoCam Plus is a capsule endoscopy (CE) system that utilizes four cameras to capture a panoramic view. This has theoretical advantage over conventional forward-viewing CE with limited field of view. Its ease of administration without requiring any additional equipment during the recording also provides a unique opportunity for patients to self-administer the test. We aimed to evaluate real-life experience using this novel system and to determine feasibility of a remote access program. METHODS: Retrospective chart review was conducted for consecutive adult outpatients who underwent CE using CapsoCam Plus. Patients with significant challenges for in-person procedures were selected for remote access through mail courier services. Gastric transit time, small bowel transit time, completion rate, diagnostic yield and adverse events were compared between remote access versus usual practice. RESULTS: Ninety-four patients (52.1% male) were included, with 28 in remote access program. Most common indication was gastrointestinal bleeding (85.1%). Complete examination was achieved in 87 patients. Five (5.3%) patients’ capsule remained in stomach during the recording, while two (2.1%) patients missed capsule retrieval. Median small bowel and gastric transit times were 231.9 (interquartile range [IQR] 169.5–308.2) and 27.6 (IQR 13.8–63.5) minutes, respectively. Diagnostic yield was 23.4%. There was no difference in completion rate or transit times between two groups, but diagnostic yield was higher in remote access group (odds ratio 3.80, 95% confidence interval 1.28–11.31). One patient required elective endoscopic retrieval of capsule. CONCLUSION: CapsoCam Plus can be safely administered remotely with a high degree of success, which may facilitate timely investigations while limiting nonessential physical interactions during pandemic.
