[The elective use of protective colostomy in rectal resection surgery].

To clarify the indications and clinical value of "protective colostomy" in cases of low colorectal anastomoses, some recent series are analyzed and compared to the experience of the authors, which includes 65 low anterior resections of the rectum for cancer, with colorectal anastomosis at less than 10 cm from the anus. "Protective colostomy" seems not to prevent the onset of anastomotic fistulae, but appears effective in reducing its clinical effects. "Protective colostomy" seems convenient when there is an increased risk of fistulization, as indicated by a series of factors defined by the authors. In doubtful cases "protective colostomy" may be performed but not opened. So the patient will be given the maximum safety, and not submitted to the uneasiness of an open colostomy unless needed.
