ABSTRACT
Figure 16.1. Diagnostic laparoscopy and trocar placement. Diagnostic laparoscopy is performed prior to the extraperitoneal dissection to inspect the peritoneal cavity and rule out carcinomatosis. This is carried out using an umbilical port and a right lower quadrant port. During this step, the pelvis can be inspected for bulky lymphadenopathy. Trocar placement for the extraperitoneal dissection is illustrated in this photograph. A 15-mm incision for the finger dissection is made 3-4 cm medial to the left iliac spine. Two accessory trocars are used: a 10-mm trocar is placed in the left mid-axillary line and a 5-mm trocar is placed in the anterior axillary line approximately 5 cm below the rib cage.
