Abstract
(Objective) A FDA alert in 2011 warned about postoperative chronic pain following transvaginal mesh (TVM) for pelvic organ prolapse (POP). We studied cases with chronic pain after TVM, natural tissue repair (NTR) and laparoscopic salcocopopexy (LSC). (Methods) We retrospectively reviewed medical charts of patients who underwent POP operations in our hospital or were referred to us after POP operations in other hospitals between 2006 and 2016. Postoperative chronic pain was defined as persistent pain for more than three months following the first three months from the time of POP operations.Patients' characteristics and treatments were analyzed. (Results) In patients who underwent POP operations in our hospital, the rates of chronic postoperative pain after TVM, NTR and LSC were 12/2,457 (0.49%), 1/402 (0.26%) and 0/29 (0%), respectively. Another 8 patients were referred to us after POP operations in other hospitals. Thus, a total of 21 patients (15: TVM, 6: NTR) had either medications, surgical treatment or were referred to other doctors due to postoperative chronic pain. All of them were parous women aged 53 to 81 years old. Preoperative chronic pelvic pain was found in seven patients (33%), and another four patients (19%) had orthopedic diseases with chronic pain. The main locations of pain were; vagina 11, vulva 2, urinary bladder 2, urethra 1, coccyx 1, buttocks 1, anus 1, perineum 1 and groin 1. Nineteen patients had pharmacological treatment using tricyclic antidepressants, Ca2+ channel α2δ ligand and/or serotonin-noradrenalin reuptake inhibitor (SNRI); 9 (47%) of the patients showed a notable improvement. Three patients following TVM had surgical treatment; one with bladder mesh exposure was resolved with TURis, one with vaginal mesh exposure was resolved with mesh trimming, but one with tenderness on the mesh arm did not improve after a partial mesh removal. Four patients were referred to pain clinics. (Conclusions) Postoperative chronic pain can occur following both TVM and NTR therefore, attentive listening and proper medication are important as initial therapies. It is mandatory to examine the presence of mesh exposure in patients after using mesh. We should be careful about preoperative chronic pain, pelvic or elsewhere, as a risk factor for postoperative chronic pain.
