    Abstract:
    The biofragmentable anastomosis ring (BAR) is composed of polyglycolic acid and barium sulfate. When used for intestinal anastomosis, the BAR fragments after the anastomosis is established. We used this device in 43 patients. In three patients, the anastomosis with BAR was abandoned due to technical difficulties. A total of 43 anastomoses with BAR were performed in 40 patients. The operations in which BAR was used included right hemicolectomy in 12 patients, transverse colectomy in 7, sigmoidectomy in 11, small bowel resection in 5 and other bowel resections in 8. The time spent for the BAR anastomsis ranged from 7 to 30 min with a mean of 15.2 min, which was significantly shorter than that of conventional hand-sutured anastomosis in 23 cases. The fragmentation and excretion of the BAR occurred from 14 to 49 days later with a mean of 21.8 days. There was only one instance of anastomotic leakage (1/40, 2.5%), which occurred in a patient with a cytomegaloviral infection of the intestine. A postoperative barium enema study in 28 patients showed no passage disturbance through the anastomosis. In conclusion, the anastomosis using BAR is considered to be a simple, safe, and fast method for performing either colonic or small intestinal anastomosis.
