History of Lps LND

• 1987, the French GY oncologist Dr Daniel Dargent.− First to report endoscopic surgery in the GY oncologic field

by using retroperitoneal pelvicoscopy in performing PLNS in patients with Cx ca.

• 1992, Childers et al. and Nezhat et al.− First to report the efficacy of transperitoneal PALND for staging surgery of invasive

GY malignancies

Transperitoneal vs. Extraperitoneal

• Transperitoneal approach− Greater working space− Familiar landmarks− Excellent access to the PLNs− Sometimes requires bowel mobilization.

• Extraperitoneal approach− Excellent exposure to the PALNs− Excellent exposure even in obese Pt. and Pt. with s/p abdo. op.− Decreased risk of direct bowel injury, and bowel adhesion formation

• No significant differences in the frequency of complications

1 설명: A. 5 trocars: one at the umbilicus, one at the suprapubic area, two at the lower quadrants, and a 10-mm trocar at the left upper quadrant, which is used as a retractor or for removal of lymph nodes B. 5 trocars (two 10-mm and three 5-mm). The 10-mm laparoscope was introduced at the midpoint between the umbilicus and the xiphoid process (LeeeHuang point), and all other ancillary ports were inserted laterally C. The initial entry is placed at the umbilicus to evaluate the abdominal cavity. Subsequently, 10-mm trocars are placed 3e4 cm medial to the left iliac spine, another 10-mm or 5-mm trocar is inserted at the external clavicular line under the subcostal margin approximately 5 cm above the initial point, and one more 5-mm or 10-mm trocar is placed 3e5 cm cephalad to the previous trocar.

Pelvic LND

Book. Atlas of Operative Surgical Oncology. 2017

• Most of PLNs lie anterior, medially, & posteriorly to the external & internal iliac vessels & ON.− A few nodes that lie lateral to these structures,

between the vessels & the pelvic sidewall

Level of LND

Level I• Cephalad: IIA• Caudal: Cloquet LN• Lateral: genito-femoral nerve• Posterior: Pre-rectal nodes and nodes

posterior to the obturator nerve. • includes nodes in the regions of the

internal and external iliac vessels, obturator fossa, pre-sciatic fossa of Marseilles and prerectal nodes.

Further discussion

• Where is the best position for operator?

• Which energy device is the best?

• Do coagulants increase the risk of infected lymphocele?

• What is the best techniques for surgical exposure during PALND?

• Suturing (port closure 2.5mm, straight long needle)• Fan retractor with five fingers

25

Complications of PLND

• Intra-OP− Obturator nerve injury: 0-5.1%− Ureteral injury: <1% (d/t misapplication of a clamp, ligation with a suture)− Vascular injury: rare (mainly from IIV & obturator venous plexus)

• Post-OP− Lymphedema: 1.5-28%− Lymphocele: overall incidence 20%, symptomatic 6%− DVT± PTE: 0-8%− Lymphorrhea from the vagina− Lymphatic fistula, chylous ascites: uncommon

Learning curve

• 10 cases, necessary for each approach to become proficient• Extraperitoneal LND has a steep learning curve similar to that for transperitoneal LND.
