Effect of early enteral nutrition on gastrointestinal motility after subtotal gastrectomy / 中华消化杂志

ABSTRACT

Objective To observe the influence of early postoperative enteral feeding on gastrointestinal motility after subtotal gastrectomy. Methods From December 1999 to February 2001,18 patients with advanced gastric cancer who had underwent gastrectomy were randomly allocated into enteral nutrition(EN) group ( n =9) and control group( n =9). The migrating motor complex (MMC) was recorded by Synectics MicroDigitrapper antroduodenal manometry and data was analyzed by Polygram software. Results MMC disappeared after subtotal gastrectomy in all patients,the first MMC recurred from 34 mins to 4 hours after the operation,while there was no significant difference between two groups. However,MMC in EN group was different from those in normal group which was lack of phase -Ⅱ at the early postoperative stage,the variation of MMC trended to become normal during 72 hours of consecutive observation. Compared with control group,the duration of MMC-phase-Ⅲ,area under the curve,transmit speed and motility index were different in EN group. Conclusion Early postoperative enteral feeding can help re-build the normal gastrointestinal motility .Further studies about patients' selections and nutrition preparations are needed.
