Murphy's button revisited: Clinical experience with the biofragmentable anastomotic ring

Use of the biofragmentable anastomosis ring (BAR) was attempted in 33 patients at two New York City institutions and employed in 31 instances. Anastomoses performed were end-to-end enterocolic (n = 15), colocolic (n = 15), and side-to-side colocolic (n = 1). Patients ranged in age from 27 to 86 years, with the following diagnoses: primary colon cancer, 15; sessile adenoma, four; colostomy, five; diverticulosis, two; metastatic cancer with obstruction, multiple polyposis, perforated appendiceal mass, malignant carcinoid of appendix, intussuscepting right colon mass, one each. In two instances use of the device was aborted because of concern with the blood supply to the bowel wall in one and tissue edema in another. The average duration of postoperative ileus was 4.7 days. Two patients were subsequently treated for small bowel obstruction thought unrelated to use of the anastomotic device. There were no deaths and no evidence of stricture.
