Abstract
in English, Spanish

Background: Gastroduodenal artery (GDA) pseudoaneurysm is a serious complication following pancreatic resection, associated with high morbidity and mortality rates. This review aimed to report the incidence of GDA pseudoaneurysm after pancreatic surgery, and describe clinical presentation and management.

Methods: MEDLINE and Embase were searched systematically for clinical studies evaluating postoperative GDA pseudoaneurysm. Incidence was calculated by dividing total number of GDA pseudoaneurysms by the total number of pancreatic operations. Additional qualitative data related to GDA pseudoaneurysm presentation and management following pancreatic resection were extracted and reviewed from individual reports.

Results: Nine studies were selected for systematic review involving 4227 pancreatic operations with 55 GDA pseudoaneurysms, with a reported incidence of 1·3 (range 0·2-8·3) per cent. Additional data were extracted from 39 individual examples of GDA pseudoaneurysm from 14 studies. The median time for haemorrhage after surgery was at 15 (range 4-210) days. A preceding complication in the postoperative period was documented in four of 21 patients (67 per cent), and sentinel bleeding was observed in 14 of 20 patients (70 per cent). Postoperative complications after pseudoaneurysm management occurred in two-thirds of the patients (14 of 21). The overall survival rate was 85 per cent (33 of 39).

Conclusion: GDA pseudoaneurysm is a rare yet serious cause of haemorrhage after pancreatic surgery, with high mortality. The majority of the patients had a preceding complication. Sentinel bleeding was an important clinical indicator.

Antecedentes: El pseudoaneurisma (PA) de la arteria gastroduodenal (gastroduodenal artery, GDA) es una complicación grave después de la resección pancreática que conlleva elevadas tasas altas de morbilidad y mortalidad. Esta revisión tiene como objetivo estudiar la incidencia de PA de la GDA tras cirugía pancreática y describir la forma de presentación clínica y el tratamiento.

Métodos: Se realizó una búsqueda sistemática en MEDLINE y EMBASE de los estudios clínicos que analizasen el PA postoperatorio de la GDA. Se calculó la incidencia dividiendo el número total de PA de GDA por el número total de intervenciones pancreáticas. De los informes de cada caso, se extrajeron los datos cualitativos relacionados con la forma de presentación y el tratamiento del PA de la GDA tras la resección pancreática.

Resultados: Para la revisión sistemática se seleccionaron nueve estudios con 4.227 intervenciones sobre el páncreas y 55 PA de la GDA (incidencia 1,30% (rango 0,22‐8,33%). Se obtuvieron, además, datos individuales de 39 casos de PA de la GDA en 14 estudios. La hemorragia se presentó, como mediana, el día 15 (rango: 4‐210) del postoperatorio. Fue precedida de una complicación postoperatoria en el 66,7% de los casos y se observó una hemorragia centinela en el 70,0% de los pacientes. En dos tercios de los pacientes hubo complicaciones postoperatorias después del tratamiento del PA y la supervivencia global fue del 84,6%.

Conclusión: Los PA de la GDA son una causa poco frecuente, pero grave, de hemorragia después de la cirugía pancreática, con una elevada mortalidad. La mayoría de los pacientes presentaron alguna complicación previa. La hemorragia centinela fue un indicador clínico de importancia.
