A Comparative Study of Rigid and Flexible Endoscope for Treatment of Esophageal Foreign Bodies in Chaophrayayommarat Hospital

Flexible esophagoscopy, Foreign body in esophagus, Rigid esophagoscopyAbstract
This retrospective study aimed to compare the treatment of esophageal foreign bodies using two types of endoscopes: rigid and flexible endoscopy. Data collection was conducted from 1st January 2009 to 31st December 2023, involving 277 patients at Chaophrayayommarat Hospital.
The results showed that the patients were composed of 226 adults and 51 children. Treatment was performed using rigid endoscopy in 153 patients and flexible endoscopy in 124 patients. Flexible endoscopy had a 2.89 times higher success rate compared to rigid endoscopy, though this was not statistically significant (OR=2.89, 95% CI 0.09 to 1.33, P=0.1). For rigid endoscopy, most patients (44.4%) received treatment within 24-72 hours after foreign body impaction, whereas, for flexible endoscopy, 27.4% of the patients received treatment within 12-24 hours. Rigid endoscopy had a 9.61 times higher complication rate compared to flexible endoscopy, which was statistically significant (OR=9.61, 95% CI 0.00 to 0.02, P=0.00). The most common complication was esophageal mucosal injury. Treatment with flexible endoscopy resulted in a shorter hospital stay by an average of 0.89±0.73 days compared to rigid endoscopy, though this difference was not statistically significant (95% CI -0.65 to 2.43, P=0.26).
In conclusion, flexible endoscopy should be considered as the first-line treatment for esophageal foreign bodies due to its lower complication rate and shorter hospital stay. However, rigid endoscopy still plays an important role in cases involving large foreign bodies.
