Resección de adenoma velloso gigante causante del síndrome de Mckittrick-Wheelock

Abstract

Large colorectal villous adenomas are unusual. They can cause a rectal bleeding, a chronic diarrhea and less frequently a rectal obstruction and a prolapse. In addition, they can secrete a mucinous material rich in electrolytes, causing hydroelectrolyte disturbances, dehydration and acute kidney injury. In most cases, the management of these adenomas due to their size has been surgical, but endoscopic treatment has been reported with promising results, reducing the morbidity. We report and discuss the case of a 73-year-old man, who presented with syncope, with chronic diarrhea and a hydroelectrolytic alteration. Colonoscopy revealed a granular lateral spreading tumor of the rectum, and pathology confirmed a villous adenoma with a low-grade dysplasia. An initial symptomatic management of diarrhea and electrolyte disorders was performed with a subsequent surgical treatment using pull through technique with coloanal anastomosis.
