Abstract
A Spigelian hernia is a rare disease that occurs through a defect in the anterior abdominal wall adjacent to the semilunar line and lateral to the abdominal rectus. We performed laparoscopic primary repair for a case of spigelian hernia. An 82-year-old female patient was referred to our hospital for abdominal pain. Abdominal CT revealed small bowel obstruction with an incarcerated Spigelian hernia. This case was preoperatively diagnosed as a spigelian hernia, and thereby laparoscopic repair was chosen. The sac was dissected all around, and the defect was closed with polypropylene sutures. Laparoscopic repair was a safe and effective method of repairing an incarcerated Spigelian hernia.
