ALB and Hypoalbuminemia: The role of preoperative hypoalbuminemia (albumin level < 3.4 g/dL) was not examined in this study as it is a well-established independent preoperative risk factor for AL after colorectal surgery [52,53,54,55] and more recently, a 2022 systematic review and meta-analysis of 3274 patients demonstrated that a preoperative albumin level of <3.0 g/dL is also a significant risk factor of AL after bowel resection and anastomosis for ovarian cancer [56,57].
