Stapling instruments are being currently used for digestive or colorectal anastomoses with definite advantages. The authors report their initial clinical experience about BAR utilization to restore intestinal continuity after upper digestive and colorectal resections. The authors have been carried out 20 anastomoses on 18 patients: 11 males and 7 females. Eleven (61.1%) of them were affected with malignant neoplasms and in 9 cases were performed an urgency procedure. The colorectal and jejunal-jejunal anastomoses were performed, respectively, in 8 cases; gastric-jejunal and ileo-colic anastomoses, respectively, in 2. The satisfactory results obtained seem to demonstrate that the biofragmentable anastomotic ring constitutes a "safe" method of bowel junction of the whole digestive apparatus.

An examination is made of the relevant literature in the light of a case of shock due to serious hypersensitivity to high molecular weight (70,000) dextran. It is shown that similar cases occur with a certain frequency when dextran is used in situations other than surgery and frank shock. The reaction explodes in response to the first drops of the first administration. The ready availability of resuscitation equipment is a fundamental requisite for the satisfactory outcome of treatment.
