Background: Patients with prior Roux-en-Y gastric bypass (RYGB) operations for weight loss present reconstruction challenges during a pancreaticoduodenectomy (PD). With over 60,000 RYGB performed annually, the increasing odds of encountering such patients during a PD make it imperative to understand the RYGB anatomy and anticipate reconstruction options. This article describes the possible reconstruction options and their rationale.
Methods: We reviewed our PD reconstruction options, compared them to what have been described in the literature, and derived a consensus from internal conferences comprising bariatric and hepatopancreatobiliary surgeons to describe known reconstruction options.
Results: In general, reconstruction options can include one of three options: (1) remnant gastrectomy, (2) preservation of gastric remnant, or (3) reversal of gastric bypass.
Conclusion: This article describes individualized reconstruction options for RYGB patients undergoing PD. The reconstruction options can be tailored to the needs of the patient.
