[Gastric motility based on gastric impedance measurement data after truncal and combined vagotomies in duodenal ulcer].

The motor function of the stomach was investigated by the gastroimpedansometric method in 73 patients: 32 of them with ulcer of the duodenum before operation, 17--after truncal vagotomy and 13 after combined (anterior selective proximal and posterior truncal) vagotomy with Finney's pyloroplasty within the period from 4 to 10 years. Motor activity in the cardial and antral parts and the stomach body was evaluated using the computer medical complex "Gastrolog" by the indicator of local motility and contraction rate. The indicator of local motility was reliably higher in patients with ulcer of the duodenum than in healthy subjects. At later terms after truncal vagotomy a normokinetic type of motor activity was noted in all parts of the stomach, the level of motility of the antral part being reliably higher after combined vagotomy with saved anterior Latarget's nerve (p < 0.01).
