Abstract

Background: Complications after laparoscopic gynecological surgery may increase patients’ morbidity and mortality; therefore, their timely diagnosis and early treatment would help clinicians to avoid life-threatening situations. We aimed to evaluate the predictive role of fibrinogen for diagnosing complications after laparoscopic gynecologic surgery for benign and malignant conditions. Patients and methods: All patients who underwent elective laparoscopic gynecologic surgery between June 2013 and December 2017 at the Department of Gynecologic Oncology, Azienda Ospedaliera Brotzu, Cagliari, were prospectively included. Post-operative complications were assessed and graded according to the Clavien-Dindo classification. Fibrinogen and white blood cell level were determined preoperatively, on the first post-operative day and at the appearance of symptoms indicative of an irregular post-operative course or at the time of rehospitalization for persistent symptoms. The postoperative changes (calculated from the first postoperative day) were correlated with the occurrence and severity of complications and their predictive role was assessed. Results: We enrolled 1016 patients: 36% underwent surgery for benign pathologies (mainly voluminous fibromatous uteri and severe deep endometriosis) and 64% for gynecologic malignancies. The overall complication rate was of 3.45%, the rate of major postoperative complications was 2.85%. A postoperative fibrinogen increase ≥ 20% had a high diagnostic accuracy to identify postoperative complications early (AUC 0.931, sensitivity 89%, and specificity 99%). The magnitude of postoperative fibrinogen change was associated with complication severity. Conclusions: Our findings demonstrated that fibrinogen increase can enable the early detection of postoperative complications after laparoscopic gynecological surgery. Further prospective and multi-center studies are warranted to confirm these results.
