Pancreaticoduodenectomy in Patients with Previous Roux-en-Y Gastric Bypass: a Matched Case-Control Study.

Little has been reported regarding outcomes of pancreaticoduodenectomy (PD) in patients with previous Roux-en-Y gastric bypass (RYGB). We performed a retrospective case-control study of patients undergoing PD after RYGB from January 2012 through July 2017 at 2 institutions. Of the 380 patients who underwent PD, 12 (3.2%) had previous RYGB. They were matched (by age, sex, diagnosis, operative approach, and year of surgery) to 36 non-RYGB patients undergoing PD (1:3 ratio). No difference was found between groups in mean operative time, length of hospitalization, or postoperative morbidity. A history of RYGB in patients with pancreatic head pathology did not delay surgical intervention. Outcomes of PD were similar for patients who did or did not have prior RYGB.
