Laparoscopic ovarian cystectomy using a single umbilical puncture method

To establish a minimally invasive technique to perform ovarian cystectomy, the authors applied a single umbilical puncture method. A 2-month old female infant was admitted to the hospital because of an ovarian cyst that showed no spontaneous shrinkage after her birth. An umbilical semicircular incision was made to insert a 10-mm trocar, into which a 3-mm laparoscope was inserted. The ovarian cyst was grasped using forceps inserted through an operating channel of the scope, and the cyst was removed through the incision. After aspiration of the cyst, the free cyst wall was resected, leaving the intact ovarian tissue. The operation was performed without difficulty or complication. The postoperative course was uneventful. The wound was inconspicuous, and the result was cosmetically excellent. The case demonstrated the feasibility of the minimally invasive technique using a single umbilical puncture for ovarian cystectomy in an infant.
