Abstract:
OBJECTIVE: Recently, pancreaticogastrostomy (PG) has attracted renewed interest as a reconstruction technique after pancreaticoduodenectomy (PD), as it may imply a lower risk of clinical pancreatic fistula than reconstruction by pancreaticojejunostomy (PJ). We hypothesise that pancreatic exocrine insufficiency (PEI) is more common during clinical follow-up after PG than it is after PJ. RESEARCH DESIGN AND METHODS: This study compares the prevalence of PEI in patients undergoing PD for malignancy with reconstruction by PG versus reconstruction by PJ. PEI during the first year of follow-up was defined as the intake of pancreatic enzyme replacement therapy (PERT) within one year postoperatively and/or an abnormal exocrine function test. RESULTS: A total of 186 patients, having undergone surgery at two university hospitals, were included in the study. PEI during the first year postoperatively was present in 75.0% of the patients with PG, compared to 45.7% with PJ (p < 0.001). Intake of PERT within one year after surgery was found to be more prevalent in the PG group, i.e. 75.8% versus 38.5% (p < 0.001). There was a trend towards more disturbed exocrine function tests after PG (p = 0.061). CONCLUSIONS: PEI is more common with PG reconstruction than with PJ reconstruction after pancreaticoduodenectomy for malignancy.
