Radiation-free luminal stenting using peroral cholangioscope
Background and Aims
Traditional endoscopic self-expandable metal stent (SEMS) placement necessitates fluoroscopy guidance when treating gastrointestinal obstruction. This study was performed to report the safety and efficacy of radiation-free peroral cholangioscopy-guided SEMS placement in the treatment of 2 cases with gastrointestinal obstruction.
Methods
This study included 2 patients with gastrointestinal obstruction due to cholangiocarcinoma and sigmoid colon cancer. Peroral cholangioscopy was applied for radiation-free guidewire insertion and SEMS placement.
Results
The guidewire insertion and SEMS placement were successfully accomplished by radiation-free peroral cholangioscopy in both cases. It resulted in significant relief of gastrointestinal obstruction symptoms. In addition, no adverse events such as bleeding or perforation were observed intraoperatively and postoperatively.
Conclusions
Radiation-free peroral cholangioscopy may safely and effectively assist SEMS placement to relieve the symptoms of obstruction caused by gastrointestinal tumors.
