Comparison of the efficacy and characteristics of metallic foreign body extraction by incision surgery and x-ray guided forceps after body-surface projection positioning

Abstract

A foreign body retained in soft tissue may give rise to infection and dysfunction, which may pose a potential threat to patient health. Our study is to compare the efficacy and characteristics of metallic foreign body (MFB) extraction from soft tissue by incision surgery and x-ray-guided forceps after body surface projection positioning.This study enrolled 775 patients who underwent percutaneous MFB extraction between January 2011 and December 2016. A total of 257 cases underwent extraction by incision surgery and 518 cases underwent x-ray-guided forceps extraction after body surface projection positioning.All patients were diagnosed by x-ray and the diagnostic accuracy rate was 100%. In the incision surgery group, MFB extraction was successful in 193 of 257 cases. All cases in the forceps extraction group were successful, and the success rate was significantly higher than that of the incision surgery group (100% vs.75.1%, P < .01). Sixty-four patients in the incision surgery group who failed treatment were subsequently treated with x-ray-guided forceps extraction and all MFBs were extracted. The symptoms in all patients were relieved, wound healing was good, and there were no major bleeding, incision infection, or other complications.Compared with incision surgery, x-ray-guided foreign body forceps extraction after body surface projection positioning is a less invasive, safer, and more effective treatment for MFB extraction.

Diagnosis and Management of a Retained Local Anesthetic Needle Fragment in a Patient Who Underwent Scheduled Elective Cesarean Delivery: A Case Report

“…Removal of metallic foreign bodies with surgical incision had a 75.1% success rate compared to a 100% success rate for an X-ray-guided forceps technique in 1 retrospective study. 7 We would have considered leaving the needle fragment in place if the needle fragment was in a deeper location such as the epidural space or if the patient had a preference to not undergo an additional procedure to remove the needle fragment. However, our radiologist team believed their approach could successfully retrieve the spinal needle fragment.…”
