Abstract:
Objective To observe the feasibility and effectiveness of fluoroscopy-guided Fustar adjustable bent sheath clamp biopsy for diagnosing obstructive esophageal diseases.Methods Totally 29 patients with esophageal or esophagogastric junction obstruction who failed to complete endoscopic biopsy were retrospectively analyzed.Real-time fluoroscopy-guided clamp biopsy of lesion areas were performed through 10F Fustar adjustable bent sheath under local anesthesia.The technical success rate,operation time,radiation dose were recorded,and the complications were evaluated.Results Clamp biopsy of lesion areas were successfully performed in all 29 cases,with technical success rate of 100%(29/29),the average operation time of(29.81±10.05)min and the average radiation dose of(127.14±100.36)mGy.No serious complication such as esophageal perforation nor massive bleeding occurred.After biopsy,22 cases(22/29,75.86%)were preliminarily diagnosed as positive,among them 2 cases underwent surgical operation,and the postoperative pathological results were consistent with biopsy.Negative biopsy results were found in 7 cases(7/29,24.14%),among them 2 cases underwent clamp biopsy again 3 months later which showed positive results.Conclusion Fustar adjustable bent sheath clamp biopsy was feasible and effective for diagnosing obstructive esophageal diseases,which could be regarded as the substitution and supplementation of endoscopic clamp biopsy.
