ABSTRACT
BACKGROUND:
Endoscopic submucosal dissection (ESD) for anastomotic lesions is technically challenging. We aimed to characterize the clinicopathologic characteristics, feasibility, and effectiveness of ESD for anastomotic lesions of the lower gastrointestinal tract.METHOD:
We retrospectively investigated 55 patients with anastomotic lesions of the lower gastrointestinal tract who underwent ESD from February 2008 to January 2021. The lesions involving one or both sides of anastomoses were classified into the unilaterally involving anastomosis (UIA) or straddling anastomosis (SA) group, respectively. We collected clinicopathological characteristics, procedure-related parameters and outcomes, and follow-up data and analyzed the impact of anastomotic involvement.RESULTS:
The mean age was 62.5 years, and the median procedure duration was 30 min. The rates of en bloc resection and R0 resection were 90.9% and 85.5%, respectively. Four patients (7.3%) experienced major adverse events (AEs). During a median follow-up of 66 months (range 14-169), seven patients had local recurrence, and six patients had metastases. The 5-year disease-free survival and overall survival rates were 82.4% and 90.7%, respectively. The 5-year disease -specific survival (DSS) rate was 93.3%. Compared with the UIA group, the SA group had significantly longer procedure duration, larger specimen, lower rates of en bloc resection and R0 resection, and shorter disease-free survival (all P < 0.05). However, rates of AEs did not differ significantly between the two groups.CONCLUSIONS:
The short-term and long-term outcomes of ESD for colorectal anastomotic lesions were favorable. Although with technically challenging, ESD could be performed safely and effectively for lesions at the anastomoses.Palabras clave
