Comparison of a Biofragmentable Intestinal Anastomosis Ring With Appositional Suturing for Subtotal Colectomy in Normal Cats

摘要

Chronic megacolon in cats is definitively treated by subtotal or total colectomy. The biofragmentable anastomosis ring (BAR) is a relatively simple means of performing small bowel anastomoses with a minimal risk of fecal contamination. Leakage from the anastomotic site is infrequent. No foreign material is permanently left at the site. The BAR comes in a range of external diameters and closed gap sizes. Twelve normal adult cats underwent subtotal colectomy. In 6 of them, the anastomosis was made of interrupted apposing sutures of monofilament polyglyconate. The other 6 animals had repair using a BAR. Abdominal x-ray films were made daily starting 10 days postoperatively, and the animals were euthanized 30 days after surgery.
