Abstract
BACKGROUND: Small-bowel capsule endoscopy (SBCE) has become an increasingly utilized imaging modality for patients suspected of having small intestinal diseases. However, data regarding the role of SBCE in patients with Billroth II gastrojejunostomy are limited. The objective is to evaluate the safety and efficacy of SBCE in Billroth II gastrojejunostomy patients. METHODS: We retrospectively studied patients with Billroth II gastrojejunostomy who underwent MiroCam capsule endoscopy between August 2013 and October 2019. Baseline patient characteristics; gastroscopic and SBCE findings; capsule transit time; and the occurrence of adverse events were collected and compared between groups with and without anastomotic lesions. RESULTS: In total, 30 patients were analyzed in the study. The median age was 59 years, and 26 patients (86.7%) were men. The majority of SBCE positive findings including ulcers (10.0%), angioectasias (6.7%) and polyps (6.7%). In patients with (n = 10) and without (n = 20) anastomotic lesions, the anastomotic lesion was significantly associated with a delayed gastric transit time (GTT) (P = 0.026), but the two groups showed no significant difference in completion (P > 0.05). All patients underwent successful SBCE examinations without adverse events, except device transit into the afferent loop, where it remained for nearly 2 h, occurred in one case with anastomotic ulcers. CONCLUSIONS: This retrospective study demonstrates that SBCE is a safe and effective diagnostic tool in patients with Billroth II gastrojejunostomy with a favorable gastroscopic evaluation within 7 days prior. The frequently real-time monitoring is suggested due to the risk of retention in the afferent loop, and a delayed food intake is required when a prolonged stay in the afferent loop occurred.
