  • OBSERVATION OF ELECTROGASTROGRAPHIC AND GASTROINTESTINAL MOTILITY CHANGES AFTER BILIARY SURGERY

    To investigate the influence of biliary surgery on gastrointestinal motility, electrogastrography (EGG) and gastrointestinal manometry were performed in a series of 17 patients who underwent biliary operation. EGG was done in all the patients in preoperative day, the operative day and the first, second and third postoperative day for at least one hour. Gastrointestinal manometry was done in eight patients in the operative day and the first, second and third postoperative day for 4-5 hours. Recording and analysis of EGG and gastrointestinal manometry were done by computer. Results: as compared with the preoperative day, the percentage of EGG normal wave in the operative day was obviously lower (P<0.001),and percentage of EGG bradygastria and tachygastria was remarkable higher (P<0.01). From the first postoperative day, EGG frequency became normal. The EGG power was obviously low after operation till the third postoperative day. After operation, MMC in upper jejunum was rarely recorded, and in the third part of duodenum was most often recorded. Duration of phase Ⅲ of MMC ranged from 4-7 min. Contractive power and area of phase Ⅲ of MMC in the third part of duodenum changed obviously (P<0.01),and the other had no changes. Conclusion: there were good correspondence between EGG and gastric manometry. Postoperative gastrointestinal dysfunction of stomach may be mainly caused by its fast wave. There were obvious changes of gastroduodenojejunal MMC after surgery which suggested that postoperative gastrointestinal dysfuntion might be caused by abnormal MMC. Improving the recovery of MMC may shorten the duration of postoperative gastrointestinal dysfunction.
