Background And Aims:
Endoscopic submucosal dissection (ESD) is an established treatment for laterally spreading tumors (LSTs). Hybrid ESD, a novel technique, is gaining popularity for colorectal neoplasms. This study aimed to compare hybrid ESD with conventional ESD for treating LSTs.
Methods:
Data from patients with colorectal LSTs ≥ 10 mm who underwent ESD at six centers from May 2020 to April 2023 were analyzed retrospectively. The study assessed baseline characteristics, hospitalization costs, and outcomes (operative time, R0 resection rate, complications).
Results:
890 patients were included: 490 underwent conventional ESD and 400 hybrid ESD. Hybrid ESD showed significantly shorter procedure times and lower hospitalization costs compared to conventional ESD. However, the R0 resection rate and lifting sign positivity were lower with hybrid ESD. Subgroup analysis indicated potential cost savings and shorter operative times for lesions 10-30 mm with hybrid ESD, without compromising R0 resection rates. For lesions ≥ 30 mm, hybrid ESD had lower R0 resection rates despite cost savings.
Conclusion:
Hybrid ESD offers a viable alternative to conventional ESD for LSTs sized 10-30 mm, reducing procedure duration and costs while ensuring R0 resection.
