©2013 UpToDate ® Print Email Alternative port placement for appendectomy* An open technique is used to enter the peritoneal cavity and place a 5 to 12 mm Hasson trocar at the umbilicus. The laparoscope is introduced through this port and two additional 5 mm ports are placed. As an alternative, the two 5 mm ports can be placed in the "bikini line". The surgeon retracts the appendix using a grasper through a right lower quadrant port and dissects using the periumbilical port site (portrayed in red) while the assistant operates the laparoscope through a left lower quadrant port (portrayed in blue). The appendix is removed in a bag through the umbilical port. * Port placement and technique may vary amongst laparoscopic surgeons.
