Brief summary in lay language
As part of a partial pancreatoduodenectomy (PD), two different strategies for the separation of the gastrointestinal passage are applied orally. This is on the one hand the resection (prPD) and on the other the receipt (ppPD) of the pylorus. Delayed gastric emptying (DGE) after PD is a serious complication that can occur following both strategies (ppPD or prPD). Existing metaanalyzes that examine the DGE after performing one of the two methods still produce conflicting results. Large, multicenter randomized controlled trials (RCTs) on this topic do not exist. The proposed study will now address this very shortcoming. In a prospective multi-centric and register-based RCT (RRCT), the effectiveness of ppPD should be compared with that of prPD in German nationwide reality. This novel study design allows a better transferability of the results.
