Port site herniation (PSH) is a rare complication after laparoscopic surgery, usually at 10-mm and larger port sites. According to the past reports, only a few cases of PSH through 5-mm trocar sites have been reported. Here we describe a case with omental herniation through 5-mm port site after laparoscopic myomectomy. The patient was 40 years old, having laparoscopic myomectomy for 11-cm subserosal myoma with a peritoneal drain left at the lateral 5-mm port site. She was found to have omental herniation through a laterally placed 5-mm port site four days after the operation. The omentum was returned to the abdominal cavity in the emergent surgery. PSH can occur even through the 5-mm port site, especially after the inserted trocar moved repetitively through abdominal wall and drain was placed at the identical port site.
