Colorectal cancer is the most common tumor of the digestive tract in the developed world, the rectum being the most affected site. It is the third cancer that is diagnosed most frequently in the United States, Europe and Cuba [1]. In Cuba this pathology is among the first five causes of morbidity and mortality due to digestive cancer, occupying the fourteenth place as the cause of death [2]. In addition to being a subject little explored so far its incidence is increasing more and more. This cancer variety has a high rate of local recurrence after surgery, which varies between 30% and 65% in different studies. It has been shown that those patients with locally advanced rectal cancer Objective: To analyze the usefulness of endoscopic ultrasonography in the staging of patients with malignant rectal tumors. Development: Staging by endoscopic ultrasonography of malignant tumors of the rectum allows to assume appropriate therapeutic behaviors (radiochemotherapy or surgery). Conclusions: In this study it is expected to find that the staging by endoscopic ultrasonography of rectal tumors, helps in the decision of the use of adequate therapy.
Introduction: Barrett's esophagus (BE) with low-grade dysplasia represents a risk of progression towards esophageal adenocarcinoma. Hybrid-APC turns out to be an effective, safe, easy to use and relatively low-cost technique to stop this progression. Aims: to describe the therapeutic response of Hybrid-APC in patients with low-grade dysplasia in Barrett's esophagus. Method: an observational, descriptive investigation of a series of cases was carried out at the National Center for Minimal Access Surgery between December 2018 and December 2020. Twenty patients with BE histologically classified with low-grade dysplasia were included. Ablation with Hybrid APC was applied, and endoscopy was performed three and six months after the end of the treatment. The therapeutic response was evaluated through histological remission and the presence of complications. The information was processed in the statistical program SPSS, version 21. Results: mean age 50.5 (range 27-81 years). 55% (11) are male. Eighty-five percent were asymptomatic and 90% had circumferential BE. 55% (11) required a HybridAPC session. With an average of 1.4 sessions, macroscopic and histological remission without dysplasia was achieved at three and six months in 90% (18/20) and 92.8% (13/14) of the patients respectively, without witnessing complications. Conclusions: endoscopic treatment with the Hybrid-APC has a good therapeutic response, with a good histological remission and without complications, in patients with low-grade dysplasia in BE.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
