BACKGROUND: The purpose of the present study was to evaluate the efficacy of extended pancreatoduodenectomy (EPD) and standard pancreatoduodenectomy (SPD) for ductal adenocarcinoma of the head of the pancreas via meta-analysis.
METHODS: Relevant articles (published between 1995 and 2012) were compiled from online data sources. A total of nine studies satisfied the selection criteria, including a total of 973 patients (478 in the SPD group and 495 in the EPD group). Evaluation parameters included 1-, 3-, and 5-year survival, as well as mortality, morbidity, and specific morbidity outcomes.
RESULTS: Meta-analysis revealed (1) differences in morbidity (Odds ratio [OR]= 1.740; 95 % confidence interval [CI], 0.840-3.600; P = 0.140), mortality (OR = 0.890; 95 % CI, 0.560-1.400; P = 0.620), 1-year overall survival (OS) rate (OR = 1.20; 95 % CI, 0.490-2.930; P = 0.69), 3-year OS rate (OR = 0.770; 95 % CI, 0.460-1.280; P = 0.190), and 5-year OS rate (OR = 1.12; 95 % CI, 0.690-1.810; P = 0.560) were not significant between EPD and SPD. (2) For bile leak (OR = 2.640; 95 % CI, 1.040-6.700; P = 0.040), pancreatic leak (OR = 1.740; 95 % CI, 1.040-2.91; P = 0.030), delayed gastric emptying (OR = 2.090; 95 % CI, 1.240-3.520; P = 0.006), and lymphatic fistula (OR = 6.120; 95 % CI, 1.06-35.320; P = 0.040) differences between EPD and SPD were significant, whereas other specific morbidities were not significantly different.
CONCLUSIONS: Extended pancreatoduodenectomy does not improve 1-, 3-, 5-year OS rates compared to SPD and there is a trend toward increased bile leak, pancreatic leak, delayed gastric emptying, and lymphatic fistula after EPD.
