Partial lobectomy of bovine liver: a new biopsy technique.

A surgical technique has been developed for partial lobectomy of the bovine liver to obtain greater than 25 gram liver samples. Vertical mattress sutures, backed with plastic tubing, were replaced in the liver near the incision line to provide hemostasis. Hemostasis of the cut surface of the liver was adequate in each case. Postoperative recovery was uneventful and only minor adhesions were found later by laparotomy and at necropsy.
