BACKGROUND

Postoperative complications are frequent after gastrointestinal surgery and early prediction remains an unmet need. Serum albumin shows a rapid decrease after surgery, and this decline (ΔAlb) may reflect the intensity of the surgical stress response and thereby be a predictor of postoperative complications. This study aimed to comprehensively review the available data on ΔAlb in gastrointestinal surgery.

METHODS

PRISMA guidelines were followed to conduct a systematic review of the literature in MEDLINE and Embase. Studies assessing the role of ΔAlb to predict complications after gastrointestinal surgery were included.

RESULTS

A total of 1256 articles were screened, and 16 studies were included in the final analysis: 7 prospective and 9 retrospective trials. Sensitivity of ΔAlb to predict postoperative complications ranged from 63 to 84%, whereas specificity ranged from 61 to 86%. Nine out of the 16 included studies established a threshold of ΔAlb to predict morbidity (range: 5-11 g/l or 14-27%).

CONCLUSION

ΔAlb appeared as a valuable and promising biomarker to anticipate complications after gastrointestinal surgery. Future efforts are needed to determine whether and how ΔAlb may be integrated in clinical practice to guide clinicians in the perioperative management of patients.
