Oxidized regenerated cellulose resembling vaginal cuff abscess

Area of Science:

• Gynecologic surgery
• Surgical hemostasis
• Medical imaging

Background:

• Oxidized regenerated cellulose (ORC) is frequently used for hemostasis in laparoscopic procedures.
• The imaging characteristics of ORC can resemble those of a postsurgical abscess.
• This resemblance poses challenges in interpreting diagnostic imaging studies.

Observation:

• Three patients developed signs and symptoms suggestive of an abscess after ORC placement during laparoscopic gynecologic surgery.
• Computed tomography (CT) imaging presented difficulties in distinguishing ORC from abscess formation.
• Specific radiologic findings were identified to differentiate between ORC and vaginal cuff abscesses.

Findings:

• Oxidized regenerated cellulose exhibits distinct imaging features that differentiate it from abscess formation.
• Accurate intraoperative documentation of ORC placement is crucial.
• Radiologists can distinguish ORC from abscesses with careful evaluation of imaging characteristics.

Implications:

• Clear communication of ORC presence and location to radiologists is essential for accurate diagnosis.
• Distinguishing ORC from abscesses aids in appropriate clinical management and patient care.
• Improved understanding of ORC imaging can prevent misdiagnosis and unnecessary interventions.
