Spigelian hernia is a rare congenital defect of the anterior abdominal wall located along the semilunar line through the aponeurosis fascia of the transversus abdominis muscle. It represents 1%-2% of all abdominal wall hernias. Few cases of laparoscopic treatment for Spigelian hernia have been reported, especially in Japan. However, several reports of laparoscopic surgery to repair Spigelian hernias have been published, and some have shown that the laparoscopic approach repair is feasible because it is associated with less morbidity and a shorter hospital stay than open surgery. We herein describe a 63-year-old Japanese woman who presented with painful bulging in the right lower abdominal quadrant. A preoperative diagnosis of Spigelian hernia was made, and we performed laparoscopic intraperitoneal repair. The patient was discharged 6 days after laparoscopic surgery with no perioperative complications. This report describes the first successful laparoscopic intraperitoneal mesh repair of Spigelian hernia in Japan.
