Background:
A high surgical technique is required for laparoscopic anterior resection using single-incision laparoscopic surgery such as multiport surgery. We report a novel surgical technique of umbilical incision laparoscopic surgery with one assist port which could be performed like conventional multiport surgery.
Methods:
With the patient in the lithotomy position, a 3-cm longitudinal skin incision is made at the umbilicus and carried down to the peritoneum. A 12-mm and two 5-mm trocars are placed through the incision. Another 12-mm trocar is placed for the insertion of laparoscopic coagulation shears and a stapler in the right lower quadrant. After surgery, the trocar in the right lower quadrant is removed and a drain is replaced through the insertion site. The operator mainly uses two trocars, a 5-mm trocar placed at the umbilicus and a 12-mm trocar in the right lower quadrant, making it like conventional laparoscopic surgery.
Results:
The median operation time was 195 (range 180-205) min, intraoperative blood loss was 20 (range 0-60) ml, and none of the 3 patients had any complications postoperatively.
Conclusion:
As opposed to surgery with only three ports, so-called single-incision laparoscopic surgery, this operation can be performed much more comfortably if another port is inserted in the right lower quadrant.
