In this work, the authors describe their own experience concerning emergency surgery on large bowel. Frequently, in emergency surgery, the primary disease is associated with a picture of heavy peritonitis that in most cases needs very difficult and immediate operation including intestinal derivation (temporary colostomy). The possibility of restoring the intestinal continuity during the first surgical operation, is the primary aim of the surgeon. Therefore, availability of tools such as BAR (Biodegradable Anastomotic Rings) in performing intestinal anastomosis characterized by strong reliability if compared to stapler suturations avoids temporary colostomy otherwise necessary. This work refers to retrospective study in a group of patients who underwent colic resection with immediate restoration of the intestinal continuity without a protection colostomy. Actually, using biodegradable anastomotic rings like BAR when performing the anastomosis, has some technical advantages, such as low incidence of intra and postoperative complications, short hospitalization period and better management of the patient.
