Complete surgical excision is the standard treatment for hydrocele of the canal of Nuck. We developed a novel open posterior wall technique for laparoscopic transabdominal pre-peritoneal (TAPP) excision. A 38-year-old woman with a 5-month history of a painless reducible lump in the right groin had recently noticed a slight increase in the size of lump. Computed tomography showed a simple cystic lesion measuring 30 × 27.5 mm. We performed laparoscopic excision of the hydrocele by using the TAPP approach and the open posterior wall technique developed by us. Complete excision of the hydrocele was satisfactorily performed because the region from the external inguinal ring to the periphery could be clearly observed. After an uneventful postoperative course, the patient was discharged. Laparoscopic TAPP excision with open posterior wall technique was useful for complete excision of hydrocele of the canal of Nuck.
