Abstract
In light of the legal issues and the shortage of data on histopathological findings, we summarized our experience on how explanted vaginal mesh specimens were managed in a surgical pathology practice during the last 5 years. Clinical history and pathology reports were collected from 155 women undergoing transvaginal tape excision. The degree of chronic inflammation, fibrosis, foreign-body giant cell reactions, the number of capillary vessels and nerve fibers, and the presence or absence of adipose tissue were recorded. Among the 155 patients, 65 (41.9%) were active medicolegal cases, with a significant increase in recent years. The main medical indications for mesh excision were pelvic pain, mesh erosion, voiding dysfunction, genital organ prolapse, and vaginal bleeding. In most cases, mild to moderate chronic inflammation with a mild degree of foreign-body giant cell reaction and minimal to mild fibrosis were found in explanted mesh specimens. The specimens were well vascularized without any evidence of nerve abnormality. Patient age correlated negatively with vaginal pain (P = .007) but positively with erosion (P = .005). In addition, the presence of adipose tissue within the explanted mesh correlated significantly with pelvic pain (P = .016). Overall, there was good tissue integration in all specimens. Considering the significant increase in the number of lawsuits in recent years, we recommend that all explanted vaginal mesh specimens be examined microscopically as well as grossly. A list of microscopic findings, including the presence or absence of adipose tissue, is suggested.
