Background
The distorted anatomy in patients with obstruction renders colon stent placement difficult. Here, we propose two novel techniques for stent implantation.
Methods
Patients in whom there was difficulty placing the guidewire with the normal method were retrospectively included in our study. All of the patients underwent the technique of combining a slim gastroscope with a normal colonoscope. We assessed the technical success, clinical success, and adverse events associated with self-expanding metal stent placement.
Results
From June 2018 to June 2020, 30.5% of patients with difficult catheterization were included in this study. Finally, stents in 17 of 18 patients (3 rectum, 13 sigmoid colon, 1 descending colon, and 1 hepatic flexure) (94.4%) were placed successfully, assisted by a slim gastroscope with or without radiography, and the obstruction was relieved. Only one remaining patient experienced failure. No intraoperative or 30-day postoperative morbidity or mortality was observed.
Conclusion
The present study showed that the stent implantation technique assisted by a slim gastroscope combined with a normal colonoscope was a relatively safe and effective method for abolishing difficult intestinal stenosis. More studies are needed to compare the advantages and disadvantages of this technique with normal endoscopic implantation.
