RESUMO
PURPOSE: Pylorus-preserving pancreatoduodenectomy (PPPD) is an alternative surgical procedure for periampullary lesions. Early delayed gastric emptying is the most common and frustrating complication in the immediate postoperative period after PPPD and late delayed gastric emptying has been reported in some long-term follow-up studies. We evaluated the incidence of early delayed gastric emptying and analyzed temporal changes in gastrointestinal function after PPPD. METHODS: The incidence of early delayed gastric emptying was retrospectively evaluated from the medical records of 15 patients who underwent PPPD. Gastric emptying tests (GETs) using 99mTc-DTPA scan were performed on 11 of the patients every three months until 1 year, where possible. RESULTS: The incidence of early delayed gastric emptying was 6.7%. Five of the eight patients (62.5%) and six of the eight (75%) who underwent scintigraphy at 3 months and 6 months respectively, showed delayed gastric emptying. But at 12 months, all of the four patients who underwent GETs showed normal gastric emptyings. CONCLUSION: The incidence of early delayed gastric emptying after PPPD was 6.7%. Though there were few symptoms in long-term follow-up study using 99mTc-DTPA scan, delayed gastric emptying was frequently observed 3 to 9 months after PPPD. However, gastric emptying might be normalized in almost all patients around 1 year after PPPD.
