[Hypersecreting villous rectosigmoid tumors. Apropos of 14 cases].

Villous recto-sigmoidal tumors with severe fluid and electrolyte loss are rare. We report here fourteen new cases with severe electrolyte imbalance (hypokalemia, hyponatremia, renal failure). We analysed too electrolyte loss in stools and we researched electrocardiographic disorders. Finally, we reported a long-term evolution of these patients.
