ABSTRACT
Colorectal cancer (CRC) is one of the most frequent worldwide. Approximately one third of cases originate from the serrated pathway of carcinogenesis, with colonic sessile serrated lesions (SSL) being the main cause of interval CRC. OBJECTIVE:
To evaluate the clinical, endoscopic, histological characteristics and endoscopic management of colonic LSS. MATERIALS ANDMETHODS:
Observational, descriptive, retrospective study from July 2017 to June 2019 in the gastroenterology service of the Guillermo Almenara Irigoyen National Hospital, Lima - Peru. The characteristics of 79 LSS were evaluated, the chi-square statistic was used to analyze the association of clinical and endoscopic variables with the presence of dysplasia; and the size of the lesion with the type of endoscopic resection.RESULTS:
In 74 patients, 79 SSL were found, 67 (84.8%) with dysplasia (44 high-grade and 23 low-grade). Average age of 52 years and 44 (59.4%) were males. The location in the right colon (OR=5.09, 95% CI 1.38â"18.7, p=0.009), the size >10 mm (OR=6.13, 95% CI 1.50â"24,94, p=0.014) and the âÅblurred edgesâ (OR=5.08, 95% CI 1.17-21.98, p=0.019), are significantly related to the presence of dysplasia. SSL smaller than 20 mm showed statistical association with bloc resection (OR=69.3, 95% CI 7.35-653.9, p <0.001) with respect to the piecemeal resection.CONCLUSIONS:
The finding of SSL during colonoscopies is frequent. The location, size and finding of blurred edges are related to the presence of dysplasia. Mucosal endoscopic resection was a safe and effective technique.
