Treatment and Prevention of Intraabdominal Bleeding in Necrotizing Pancreatitis Patients Treated With a Step-Up Approach.

OBJECTIVES

A minimally invasive step-up (MIS) approach for management of necrotizing pancreatitis (NP) has been associated with reduced morbidity and mortality compared with open surgical techniques. We sought to evaluate bleeding complications in NP patients treated with a MIS approach and to describe the management and outcomes of these events.

METHODS

An observational, cohort study was performed using a prospectively maintained NP database at a tertiary referral center from 2013 to 2019.

RESULTS

Of 119 NP patients, 13% suffering bleeding events, and 18% underwent an intervention. There was a 6-fold higher mortality rate in patients with bleeding events (n = 3; 18.8%) compared with those without (n = 3; 2.9%) ( P = 0.031). The most common intervention for hemorrhage control was endovascular coil embolization (75%), which was successful 88% of the time. Seven patients underwent prophylactic vascular intervention, which was 100% successful in preventing bleeding events from the embolized vessel.

CONCLUSIONS

Bleeding events in NP patients treated with a MIS approach are associated with a 6-fold increase in mortality. Endovascular intervention is an effective strategy for the management of bleeding events. Prophylactic embolization may be an effective technique for reducing bleeding complications.
