Clinical ScienceThe effect of antecolic versus retrocolic reconstruction on delayed gastric emptying after classic non-pylorus-preserving pancreaticoduodenectomy

BackgroundDelayed gastric emptying (DGE) after pancreaticoduodenectomy increases length of hospital stay and costs, and may be influenced by surgical techniques.MethodsWe retrospectively compared 400 patients with antecolic gastrojejunostomy with 400 patients with retrocolic gastrojejunostomy for the occurrence of DGE.ResultsThe prevalence of DGE was 15% in the antecolic group and 21% in the retrocolic group (P = .021), and median length of stay was shorter for the former (8 vs 10 days, P = .001). The difference was statistically significant with grade A DGE (9% vs 14%, P = .038), but not B or C. In a multivariate analysis, DGE was influenced by retrocolic reconstruction, as well as older age, chronic pancreatitis, preoperative bilirubin level, a history of previous upper abdominal surgery, and postoperative pancreatic fistula.ConclusionsAn antecolic gastrojejunostomy for classic non-pylorus-preserving pancreaticoduodenectomy is associated with a lower incidence of mild DGE (grade A) and a shorter length of stay.
