ABSTRACT
BACKGROUND: Prophylactic abdominal drainage (PAD) is considered a routine procedure after pancreatoduodenectomy (PD) to prevent and detect severe complications at an early stage. However, the drainage itself may cause adverse consequences. Thus, the optimal strategy of PAD after PD remains controversial. METHODS: The present paper summarizes the latest research on the strategies of PAD following PD, mainly focusing on 1) the selective placement of PAD, 2) the optimal drainage types, 3) the early removal of drainage (EDR), and 4) novel strategies for PAD management. RESULTS: Accurate stratifications based on the potential risk factors of clinically relevant-postoperative pancreatic fistula (CR-POPF) facilitates the selective placement of PAD and the implementation of EDR, with postoperative outcomes superior or similar to routine PAD placement. Both active and passive drainage methods are feasible in most patients after PD, with similar prognostic outcomes. Novel predictive models with accurate, dynamic, and individualized performance further guide the management of PAD and afford a better prognosis. CONCLUSIONS: Evidence-based risk stratification of CR-POPF aids in the management of PAD in patients undergoing PD. Novel dynamic and individualized PAD strategies might be the next hotspot in drain-relevant explorations.
