Objective:This review assesses the presentation,management, and outcome of delayed postpancreatectomy hemorrhage (PPH) and suggests a novel algorithm as possible standard of care.Methods: An electronic search of Medline and Embase databases from January 1990 to February 2010 was undertaken. A random-effect meta-analysis for success rate and mortality of laparotomy vs. interventional radiology after delayed PPH was performed.Results: Fifteen studies including 248 patients with delayed PPH were included. Its incidence was 3?3%. A sentinel bleed heralding a delayed PPH was observed in 45% of cases. Pancreatic leaks or intraabdominal abscesses were found in 62%. Interventional radiology was attempted in 41%, and laparotomy was undertaken in 49%. On meta-analysis comparing laparotomy vs. interventional radiology, no significant difference could be observed in term of complete hemostasis (76% vs. 80%; P = 0?35). A statistically significant difference favored interventional radiology vs. laparotomy in term of mortality (22% vs. 47%; P = 0?02).Conclusion: Proper and early management of postoperative complications, such as pancreatic leak and intraabdominal abscess, minimizes the risk of delayed PPH. Sentinel bleeding needs to be thoroughly investigated. If a pseudoaneurysm is detected, it has to be treated by interventional angiography, in order to prevent a further delayed PPH. Early angiography and embolization or stenting is safe and should be the procedure of choice. Surgery remains a therapeutic option if no interventional radiology is available, or patients cannot be resuscitated for an interventional treatment.
