Early Experience of Transabdominal and Novel Transvaginal Robot-Assisted Laparoscopic Removal of Transvaginal Mesh

Mesh removal after transvaginal mesh placement has typically involved transvaginal, open pelvic, laparoscopic, or a combination of approaches. Robotic pelvic mesh removal has been described in a small number of cases only. This study aims at determining the feasibility and safety of using robot-assisted laparoscopic surgery in the removal of pelvic mesh via the transabdominal and novel transvaginal approach. This is a prospective case series study on women who underwent transabdominal or transvaginal robot-assisted removal of pelvic mesh. Women were offered participation in this study with pelvic mesh and a clinical indication for mesh removal if they were older than the age of 18. Alternative surgical options, including conventional open removal of mesh, were discussed and offered to patients. The primary outcome of this study is the rate of successful removal of mesh and the 30-day complication rates. Ethics approval was obtained for this study. Thirty patients were included in this study. Median age was 62. Median operative and console time was 240 and 148 minutes, respectively. Concomitant reconstructive procedures were performed in 40% of patients. Complete or near-complete mesh removal was achieved in 83.3% of patients. For the remaining patients, partial removal of mesh was performed as planned preoperatively. Three Clavien-Dindo grade 3b complications resulted from mesh removal: concomitant ureteric and bladder injury, omental bleed, and groin wound infection. This study presents the early experience of robotic-assisted removal of transvaginal mesh with a transvaginal or transabdominal approach and demonstrates the feasibility of removal of both retropubic and transobturator mid-urethral synthetic sling as well as transvaginal prolapse meshes with transobturator and sacrospinous mesh arms. Further studies are required to expand understanding on the learning curve, operating times, complication rates, and functional outcome of this operation.
