title: Colonic anastomosis using the biofragmentable anastomotic ring and manual suture: a prospective, randomized study.
abstract: One hundred and fifty consecutive patients undergoing colonic surgery were randomized into two groups: 71 underwent hand-suture with a two-layer anastomosis of resorbable suture material (3/0 Dexon) and 79 were fitted with the biofragmentable anastomotic ring (Valtrac-BAR). Five patients, two treated using the BAR and three by suturing, developed anastomotic leakage which required a Hartmann-type reoperation. This was successful in four; one patient in the suture group died after reoperation. One patient who underwent suture had an early anastomotic stricture with fatal sequelae. Three other patients (one in the BAR group and two in the suture group) died after operation from other causes. Thus the mortality rate was 6 per cent in the suture group and 1 per cent in the BAR group. During follow-up, one patient in each group underwent reoperation for anastomotic stricture. Recovery of the gastrointestinal tract was similar in the two groups regarding duration of nasogastric drainage, intravenous fluid therapy and ileus. There was no difference between the groups in duration of hospital stay. The BAR seems to be a safe and reliable alternative to conventional suture anastomosis in colonic surgery.
