title: Excision of a urachal sinus with use of a voice-controlled laparoscope.
abstract: A 34-year-old man with an umbilical urachal sinus underwent a voice-controlled robot-assisted laparoscopic excision. In the operational procedure, three trocars were inserted into the peritoneal cavity. Exploration with a laparoscope revealed a cystic lesion at the middle part of the lower abdomen that extended about 4 cm in the major axis just from the umbilicus. The caudal stump of the urachus was ligated with an absorbable clip and divided. The cephalic side of the lesion was ligated just at the umbilicus with an Endo-Loop and divided. The lesion was then peeled from the peritoneum and taken from the peritoneal cavity. The robot allowed a safer and more secure movement of the scope. The postoperative course was uneventful, the surgical wound scars were very small, and the cosmetic results were satisfactory. There was no recurrence and no transformation of the navel. Our experience was encouraging enough to suggest that voice-controlled robot-assisted laparoscopic excision in patients with urachal disease is a beneficial therapeutic option that is easy, safe, and minimally invasive, with excellent cosmetic results.
