Causes, management, and prognosis of severe gastrointestinal bleedings in critically ill patients with pancreatic cancer: A retrospective multicenter study.

BACKGROUND

Gastrointestinal (GI) bleeding is a leading cause of intensive care unit (ICU) admission in pancreatic cancer patients.

AIMS

To analyze causes, ICU mortality and hemostatic treatment success rates of GI bleeding in pancreatic cancer patients requiring ICU admission.

METHODS

Retrospective multicenter cohort study between 2009 and 2021. Patients with a recent pancreatic resection surgery were excluded.

RESULTS

Ninety-five patients were included (62 % males, 67 years-old). Fifty-one percent presented hemorrhagic shock, 41 % required mechanical ventilation. Main GI bleeding causes were gastroduodenal tumor invasion (32 %), gastroesophageal varices (21 %) and arterial aneurysm (12 %). Arterial aneurysms were more frequent in patients with previous pancreatic resection (36 % vs 2 %, p < 0.001). Hemostatic procedures included gastroduodenal endoscopy in 81 % patients and arterial embolization in 28 % patients. ICU mortality was 19 %. Multivariate analysis identified four variables associated with mortality: performance status >2 (OR 9.34, p = 0.026), mechanical ventilation (OR 14.14, p = 0.003), treatment success (OR 0.09, p = 0.010), hemorrhagic shock (OR 11.24, p = 0.010). Treatment success was 46 % and was associated with aneurysmal bleeding (OR 29.89, p = 0.005), ongoing chemotherapy (OR 0.22, p = 0.016), and prothrombin time ratio (OR 1.05, p = 0.001).

CONCLUSION

In pancreatic cancer patients with severe GI bleeding, early identification of aneurysmal bleeding (particularly in case of previous resection surgery) and coagulopathy management may increase the treatment success and reduce mortality.
