We conclude that balloon occlusion of the hypogastric arteries is a safe and effective adjunct to cesarean hysterectomy in an attempt to minimize blood loss in patients with abnormal placentation.

The motility of the vagally denervated transposed stomach after oesophagectomy was examined by ambulatory gastric manometry and videofluoroscopy. Two groups of subjects were studied. Group 1 comprised ten patients who had undergone oesophagectomy 6-12 months previously and group 2 consisted of six normal control subjects. Studies were performed on fasting and fed subjects, and following injection of erythromycin 8 mg/kg. No distinguishable manometric wave activity was seen in either group while fasting. Feeding generated a measurable wave pattern in the patient group only. A significant increase in the mean (s.e.m.) distal wave amplitude was identified after infusion of erythromycin in both patients (34.0(15.1) versus 12.2(3.1) mmHg, P < 0.05) and controls (15.1(3.4) versus 5.0(0.0) mmHg, P = 0.05). The response to erythromycin was more rapid in patients than in controls (mean(s.e.m.) 113(16) versus 377(133) s, P < 0.05) and the effect persisted for longer (more than 1 h) in those who had undergone oesophagectomy. Videofluoroscopy confirmed purposeful motility in both the normal and vagally denervated stomach. It is concluded that the transposed stomach is a dynamic conduit. Enhancement of motility was greatest in the denervated stomach, indicative of denervation supersensitivity.
