[Biodegradable compression ring in intestinal anastomosis].

The Authors report their experience with the use of biofragmentable anastomosis ring ("Bowel Anastomosis Ring" B.A.R.--Valtrac): 34 patients underwent colic resection and bowel anastomosis by B.A.R. No complications related to the anastomosis were recorded. The ring was always discharged in the third postoperative week and the endoscopic follow up showed no late complications. It is concluded that B.A.R. is a safe technique and represents a good alternative to hand or mechanical anastomosis with a favorable cost/benefit ratio.

[Cancer of the rectum in elderly patients over the age of seventy-five years. Results of the surgical treatment].

The authors reviewed 122 rectal cancers observed over a period of 14 years in patients over the age of 75 years. Sixty-eight patients underwent extensive rectal resection, 17 were treated by local excision, and 28 only underwent a colostomy. Eight patients were excluded for surgery. The analysis of all of these groups showed that perioperative mortality was greater for large resections than for local resections, but with a lower recurrence rate and a higher survival at 3 years. Survival at 5 years after large resections was very close to the natural life expectancy for people of the same age. Moreover, survival was the quality of more comfortable than after local excision, and operative mortality was generally due to organ failure rather than to age itself. Radical surgery does not have to be systematically refused for very old patients, but he discussed in terms of the patients general status.

DNA damage induced by some bile acids, evaluated with alkaline elution technique.

Bile acids are promoting agents in colon carcinogenesis. In this work we have tried to characterize the DNA alteration induced by bile acids in Sprague-Dawley male rats. Confirming previous findings, a clear increase in elution rate was observed at alkaline pH. No effect could be observed when the nuclei were washed before the elution, in condition totally unsuitable for the repair of the type of DNA damage induced by typical genotoxic agents. We advanced the hypothesis that the increased alkaline elution rate observed with bile acids could be independent of DNA fragmentation and related to changes in chromatin structure.

[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.
