Cap-assisted endoscopy for esophageal foreign bodies: A meta-analysis

BACKGROUND

Esophageal foreign bodies are common around the world. Newer approaches, such as cap-assisted endoscopy, have been introduced as an alternative to conventional methods. Therefore, we performed a meta-analysis ono cap-assisted endoscopy versus conventional endoscopy for removal of esophageal foreign bodies.

AIM

To investigated the effectiveness of cap-assisted endoscopy with conventional endoscopy.

METHODS

An extensive literature search was performed (December 2021). For esophageal foreign body removal, cap-assisted endoscopy was compared to conventional endoscopy for procedure time, technical success of the procedure, time of foreign body retrieval, en bloc removal, and adverse event rate using odds ratio and mean difference.

RESULTS

Six studies met the inclusion criteria (n = 1305). Higher odds of technical success (P = 0.002) and en bloc removal (P < 0.01) and lower odds of adverse events (P = 0.02) and foreign body removal time (P < 0.01) were observed with cap-assisted endoscopy as compared to conventional techniques.

CONCLUSION

For esophageal foreign bodies, the technique of cap-assisted endoscopy demonstrated increased en bloc removal and technical success with decreased time and adverse events as compared to conventional techniques.
