title: Long-term postoperative functional evaluation of pylorus preservation in Imanaga pancreatoduodenectomy.
abstract: Our purpose was to determine whether pylorus-preservation in the Imanaga (PpPDI) method minimizes postoperative impairment of gastrointestinal function. Nine patients who had undergone PpPDI (postoperative years: 5.7 +/- 2.6) and nine patients who had undergone conventional Imanaga pancreatoduodenectomy (PDI) (postoperative years: 6.8 +/- 2.0) were evaluated for symptoms, nutritional parameters, and physiologic function of the biliary tract and residual stomach using gastric emptying and hepatobiliary scintigraphy. The body weight recovered to 99.3% +/- 3.8% of pre-illness body weight in PpPDI, showing a significantly better recovery than in patients after the PDI procedure (91.0% +/- 6.4%, P < 0.05). The mean gastric emptying half-time (GET1/2) in the upright position after PDI was significantly shorter (42.3 min) than after PpPDI (80.8 min, P < 0.05). Mixture of food with bile was conserved better in the PpPDI group than in the PDI group. In the long term, the pylorus-preserving Imanaga-type procedure minimizes disruption of gastric function and asynchrony between ingested food and bile.
