Objective: To describe the predisposing factors for re-resection of lateral extension colorectal lesions with mucosectomy technique without hot loop elevation at the Central Military Hospital, from 2016 to 2021. Methods: Analytical observational case-control study. Results: Thirty three patients underwent endoscopic resection of lateral extension colorectal lesions with mucosectomy technique without hot loop elevation at the Central Military Hospital in the study period. Of these, 7 (20.5%) presented the event of interest (recurrence) were therefore chosen as cases, and the remaining 26 that did not present the event of interest were analyzed as controls. Lesion size (OR: 3.43), lesion type (OR: 16.55) and lesion location (OR: 3.7) were independent risk factors. Compared with the average age in both groups (56-68 years) it was a protective factor (OR: 0.8). Conclusions: The non-elevation mucosectomy technique performed at the Central Military Hospital has a lower rate of recurrence and complications compared to other techniques described in the world literature, data that should be analyzed in prospective studies.
