title: [Surgical treatment of villous tumors of the rectum and sigmoid. Apropos of 79 cases].
abstract: The authors analyse a series of 79 villous tumors of the rectum and sigmoid. These tumors are observed more often in men at an average age of 65. They distinguish benign tumors (44 cases), premalignant (21 cases) and malignant tumors (14 cases). The histology of the whole piece has a greater value than a preoperative biopsy. There are many clinical symptoms and the forms with electrolyte depletion are not rare (6 cases). Tumors with wide implantation need a surgical treatment. It will be conservative in benign cases, but the excision will be wide in cases of invasive malignancy. The indication are based upon the localisation of the tumor on the rectum. Mortality of wide excision is quite important (10) because of the bad general feature of the patients. Recurrences must be detected early by regular endoscopic follow-up.
