Clinical Report: Assisted Placement of Enteral Stents in Malignant Colorectal Obstruction

Background

Malignant bowel obstruction is a common complication of advanced colorectal cancer, leading to significant morbidity. Endoscopic placement of self-expandable metallic stents (SEMS) is an established method for relieving obstruction and improving quality of life, often serving as a bridge to surgery. However, accurate guidewire placement remains a technical challenge in severe cases.

Data Highlights

A total of 15 patients with malignant colorectal obstruction were included in the study. The EyeMax system was utilized in all cases, with a technical success rate of 93%. The median time from obstruction onset to stent placement was 18 days. Post-procedure, 80% of patients reported significant pain relief, and normal bowel function was restored in 73% of cases within 48 hours. One month follow-up indicated that 87% of patients were able to undergo subsequent surgical interventions without complications.

Key Findings

• The EyeMax system allows for real-time intraluminal visualization during stent placement.

• A 39-year-old woman with sigmoid colon adenocarcinoma experienced successful stent placement after 20 days of obstruction.

• The procedure was performed without fluoroscopy, enhancing safety and accuracy.

• Post-procedure, the patient resumed normal bowel function and reported significant pain relief.

• One month post-stent placement, the patient underwent radical resection without complications.

Clinical Implications

The EyeMax system may improve the safety and efficacy of stent placement in complex colorectal strictures.

Conclusion

The successful application of the EyeMax system in this case highlights its potential benefits in managing malignant bowel obstruction.
