PURPOSE: To evaluate the incidence and characteristics of the unabsorbed polylactide adhesion barrier with increased (18)F-fluorodeoxyglucose ((18)F-FDG) uptake after surgeries for gynecologic malignancies. METHODS: Between September 2006 and November 2009, we reviewed the charts of 75 patients who were provided a polylactide adhesion barrier after surgery for gynecologic malignant diseases. We surveyed the cases of increased (18)F-FDG uptake on positron emission tomography/computed tomography (PET/CT), and evaluated the effectiveness of polylactide adhesion barrier using an adhesion scoring system. RESULTS: Ten patients (13.3 %) had a solitary pelvic mass with increased (18)F-FDG uptake in the follow up PET/CT. The characteristics of patients and tumors are described below. The median age was 48 years (range 19-66 years). The median tumor size was 1.9 cm (range 1.0-2.3 cm), and the median SUVmax of the pelvic mass was 5.1 (range 3.7-7.9). The median time between initial operations and second operation was 13.5 months (range 8-23 months). We performed laparoscopic excision of the pelvic mass, and the biopsy revealed foreign body reactions with the exception of 1 case, which contained tumor cells under the unabsorbed polylactide adhesion barrier. The median adhesion grade was 1 (range 0-2). CONCLUSIONS: A solitary pelvic mass found in the PET/CT with increased (18)F-FDG uptake after usage of a polylactide adhesion barrier may be an unabsorbed remnant. The adhesion barrier should be used with caution in patients with gynecologic malignant diseases.
