For several weeks a 15-year-old girl had complained of increasing abdominal pain with vomiting. On admission to hospital the bloated abdomen was diffusely sensitive to pressure and the bowel sounds were high pitched and loud. Erythrocyte sedimentation rate was increased to 23/40 mm and the white cell count to 12,000/microliters. Ultrasound examination revealed an echo-dense area with dorsal echo loss at the gastric side of the pylorus. X-ray films of the stomach showed fluid levels and a soft-tissue mass in the left upper abdomen. At laparotomy a large (12 x 6 cm) trichobezoar was found in the middle of the small intestine and two smaller ones at the pylorus. Subsequently the patient admitted to trichophagia but refused any psychological treatment.

In study of screw-dense-fixation-ring method in 15 cases of a dog's femoral artery, end to end, was reconstructed. The anastomoses is achieved by vessels of 3 - 6 mm diameter. Within a period of 1 - 6 months post-operatively, average of 3 months, angiographic control of all cases showed no complications such as aneurysm or stricture. The construction of screw-dense-fixation-ring seems to give a considerable result, because the power which is keeping the rings together, can be controlled.
