Abstract
A 10-month-old beagle dog with perforative peritonitis after spontaneous excretion of a string foreign body was operated. Although swelling of the intestines and edema of the mesenteric border from the lower duodenum to the upper jejunum were obvious, debridement and suture of two perforated portions were performed as an initial operation. However, perforation replapsed on the 4th day of postoperation. Extensive excision of the swollen intestines was undertaken with the excellent prognosis. It was suggested that the extensive intestinal resection must be performed at an earlier phase of the diseases in such cases with an entensive laceration of the intestine by a string foreign body.
