Objective:
We examined laparoendoscopic single-site surgery (LESS) for urachal remnants and evaluated its usefulness and efficacy.
Patients And Methods:
From August 2011 to July 2012, we underwent this surgery for 5 patients (3 males, 2 females). The mean age was 30.8 (25-36) years old. A 2 cm incision was made around the umbilicus and Access Platform was placed. The entire urachal tissues were excised, and this 2 cm incison was reshaped as the umbilicus.
Results:
The median operative time was 220 (156-460) minutes, and the median operative blood loss was 10 (10-70) ml. They had no operative complications, and were discharged 6 (5-14) days after surgery.
Conclusions:
Our surgical procedures have very excellent cosmesis and advantages in particular for young because we reshape as the umbilicus the surgical wound. We think that this surgery can be performed safe and effectively for surgeons trained in the conventional laparoscopic procedures.
