Study Objective:
To show the feasibility of the laparoscopic extraperitoneal approach for pelvic metastatic lymph node debulking in locally advanced cervical cancer.
Design:
A surgical video article (Canadian Task Force classification III).
Setting:
A university hospital.
Patient:
A 52-year-old patient presented with stage IIA2 cervical adenocarcinoma according to Fédération Internationale de Gynécologie et d'Obstétrique classification. During the physical examination, a 45-mm tumor was discovered. Positron emission tomographic imaging was positive for hypermetabolic enlarged lymph nodes in the left external iliac region of 1.4-cm size and an standardized uptake value of 21 and in the right obturator region of 1.3-cm size and an standardized uptake value of 7.1; no aortic nodes were found using the imaging procedures. Before chemoradiation therapy, she underwent extraperitoneal aortic lymph node dissection for surgical staging at Vall d'Hebron University Hospital, Barcelona, Spain. Pelvic lymph node debulking was proposed to confirm positivity and, if so, to adjust the radiotherapy field and reduce lymph node radioresistance [1,2].
Interventions:
After a complete extraperitoneal aortic infrarenal lymph node dissection as described by Querleu et al [3], the presacral space is created to expose the iliac vessels. The enlarged lymph nodes are identified and dissected using blunt dissection, monopolar energy, and a vessel sealing device.
Measurements And Main Results:
There were no intraoperative or postoperative complications. The anatomopathologic study confirmed positivity for adenocarcinoma metastasis in 3 pelvic nodes and 2 of 29 aortic nodes.
Conclusion:
Laparoscopic debulking of enlarged pelvic lymph nodes via the extraperitoneal approach is a feasible procedure. It can be performed as an extension of extraperitoneal aortic lymphadenectomy in selected patients with locally advanced cervical cancer.

01:23Detailed Structure and Function of Lymph Nodes
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...
02:22Overview of Advanced Functional Groups
Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
