Laparoscopic repair with cone-shaped mesh implantation for perineal hernia occurred after laparoscopic abdominoperineal resection

INTRODUCTION: Perineal hernia after abdominoperineal resection (APR) is a rare complication, and no standard surgical procedures are established. We describe a simple laparoscopic mesh implantation technique utilizing a large synthetic flat mesh. PRESENTATION OF CASE: We report a case of perineal hernia after APR. We performed laparoscopic repair using a soft and large synthetic mesh with simple technique. The essence of this technique is that mesh is inserted into the abdominal cavity without trimming and it forms in a conical shape to better adjust to the pelvic cavity. DISCUSSION: The perineal and laparoscopic approaches for perineal hernia repair have been performed most commonly in recent years, but the recurrence rate after repair remains high (24.1%). Using a large mesh could cover the hernial orifice with a sufficient margin, reducing a risk of recurrence caused by shrinkage and slippage of the mesh. CONCLUSION: Our technique utilizing a large, lightweight, synthetic mesh can be practical and useful for perineal hernia repair after laparoscopic APR.
