1. Study design and patient selection
After obtaining the approval of institutional review board (Approval no: 2020/8-2), a retrospective review of the patients who underwent an intestinal anastomosis during the gyne-oncological surgeries between September 2017 and March 2021 was performed at an ESGO (European Society of Gynecological Oncology) accredited center in Turkey (Tepecik Education and Research Hospital, Izmir). Patients’ hospital files, pathology and radiology reports, and laboratory results were throughly reviewed. Exclusion criteria were defined as R2 cancer resection (gross residual disease) and non-gynecological malignancies according to final pathology report. Collected data included patient’s age, body mass index (BMI) (kg/m2), ASA (American Society of Anesthesiologists) score, type of the malignancy, operative procedure, patient outcome, and the serum levels of biomarkers taken through the hospitalization time.
