Abstract
A 67-year-old male patient was admitted to our hospital with lower left abdominal pain. The patient had undergone herniorrhaphy by direct Kugel repair for a left inguinal hernia approximately 8 years previously at another hospital. An abdominal computer tomography scan revealed a non-enhanced mass in the lower left abdomen. Based on the results, the patient was diagnosed with a retained surgical sponge and laparoscopic surgery was performed. The intra-abdominal tumor was covered by hard peritoneal fascia and old gauze was present inside. The old gauze was removed using the trans-abdominal pre-peritoneal technique. There were no surgical complications.
