Modification of the Interdigestive Migrating Motor Complex (IMMC) in Patients with Partial Gastrectomy and Gastrojejunostomy
The interdigestive motor activity of the stomach and proximal jejunum was recorded with a manometric probe in 8 patients who underwent partial gastrectomy and gastrojejunostomy (Billroth II) for duodenal ulcer (PG group), in 9 normals (N group) and in 5 patients with duodenal ulcer (DU group). The latter two groups were considered as controls. In the PG group the motor activity was recorded from the gastric remnant and from the efferent loop, and the results were compared with recordings at similar levels in the other two groups. The probe catheters were perfused with bubble free water by using a low-compliance pneumo-hydraulic pump and were connected to transducers P 23 Db and a polygraph. The recording was carried out after 14 hours of fasting and lasted at least 180 minutes each.
