ObjectivesThis study was conducted to compare the incidences of delayed gastric emptying (DGE) following pylorus-resecting pancreaticoduodenectomy (PrPD) and pylorus-preserving pancreaticoduodenectomy (PpPD), respectively.
MethodsData for 37 patients submitted to PrPD were compared with data for a matched number of patients submitted to PpPD during the same period. A meta-analysis of comparative studies of the two techniques was also carried out. The primary endpoint was the rate of DGE (grades A-C) defined according to the International Study Group of Pancreatic Surgery criteria.
ResultsIn the case-matched comparison, both overall DGE (six PrPD patients and 17 PpPD patients; P = 0.006) and clinically relevant DGE (one PrPD and eight PpPD patients; P = 0.013) occurred significantly less often in the PrPD group than in the PpPD group. Based on eight non-randomized clinical trials and two randomized clinical trials involving 804 subjects, the meta-analysis further confirmed a significant reduction in DGE with pooled odds ratios of 0.33 [95% confidence interval (CI) 0.17-0.63; P < 0.001] and 0.13 (95% CI 0.05-0.40; P < 0.001) for overall DGE and clinically relevant DGE, respectively. Other complications and mortality were similar in both groups.
ConclusionsPylorus-resecting pancreaticoduodenectomy is a safe procedure associated with less severe and less frequent postoperative DGE than PpPD.
