Hemostatic Cellulose Masquerading as a Postoperative Abscess Following Elective Colon Surgery: A Unique Case and Literature Review.

Surgical site infections (SSIs) and intra-abdominal abscesses (IAAs) are common and costly complications following elective colon surgery, requiring prompt diagnosis and treatment. Hemostatic cellulose, a widely used intraoperative hemostatic agent, can mimic pathological lesions such as abscesses on imaging, leading to potential misdiagnoses. We present the case of a 68-year-old man who underwent elective colostomy reversal complicated by a postoperative computed tomography (CT) scan suggestive of an IAA. Upon review of the operative note and repeat imaging, the suspected abscess was determined to be a hemostatic cellulose. This case highlights the importance of meticulous intraoperative documentation and interdepartmental communication to prevent unnecessary interventions and improve patient outcomes. Additionally, it underscores the need for awareness among clinicians regarding this masquerading ability of hemostatic cellulose to avoid misinterpretation and its potential impact on both patients and hospital quality metrics.
