Para Aortic Lymph Node Dissection Technique

512017 Right-sided para-aortic lymphadenectomy is performed by dissecting the lymph nodes of the precaval and paracaval area up to the level of the origin of the right ovarian vein in the inferior vena cava IVC or the right renal vein. Lateral aortic lymph nodes are dissected from the infra-mesenteric region low paraaortic below the level of inferior mesenteric artery.

Para aortic lymph node dissection technique. 1272018 Paraaortic lymph node dissection PA lnd is an important staging technique with significant implications. Paraortic lymphadenectomy is a delicate procedure due to the necessity to dissect close to vital structures. These nodes can be classified based on its location.

Using latex balloon dissection technology the technique is as follows. However in 2018 surgical and radiologic evaluation were added to the staging system. The lung and trachea are moved anteriorly and subcarinal and hilar lymph nodes stations 7 and 10 are dissected away.

Step 2 creating a space for subsequent lymphadenectomy and identification of anatomic landmarks. The mediastinal lymph node dissection is completed by removing lymph nodes from the subaortic and para-aortic regions stations 5 and 6. A retroperitoneal space is.

Procedure can be performed from laparotomy laparoscopically or robotically. The preaortic group is located in front of the aorta where each node drains sections of the gastrointestinal tract found in the abdomen until the mid-rectumThe group can further be divided into the superior mesenteric celiac and inferior mesenteric lymph nodes according to. Focus of the video involves the.

1112019 The paraaortic lymph node dissection begins over the right common iliac artery from the mid-level caudad to cephalad direction. 10162019 We performed a minimum dissection looking for the sentinel lymph node or nodes in the pelvic and para-aortic region. The 10 steps are as follows.

2162021 Superiorly the inferior pulmonary vein is identified ligated and divided. 9192020 Para-aortic lymph node dissection was performed up to the level of renal vein superiorly including the removal of lymph nodes adjacent to aorta and vena cava. The most complex variant is systematic pelvic and paraaortic lymph-node dissection which requires removal of fatty-lymphatic tissue from anatomically strictly defined areas.

Step 4 right common iliac lymph node dissection. Any lymph node with a remarkable radioactivity count as higher as 10 times the background andor dyed with indocyanine green was considered a sentinel lymph node and was harvested separately. Step 6 lateroaortal lymph node dissection.

The patient underwent an endoscopic extraperitoneal para-aortic lymphadenectomy. Step 1 retroperitoneal access. Step 8 aortocaval lymph node dissection.

An anatomical dissection is being performed being the upper limit of the dissection the left renal vein. 712020 Over the past two years we have developed a novel technique to perform lymph node dissection in this critical area. SLN mapping has higher sensitivity for the detection of nodal metastasis despite removing fewer lymph nodes and potentially reduces morbidities such as lower extremity lymphedema.

The most complex variant is systematic pelvic and paraaortic lymph-node dissection which requires removal of fatty-lymphatic tissue from anatomically strictly defined areas. The procedure described herein uses 3- fan retractor forceps to help expose the surgical field and changed the position of the surgeon and the laparoscopic video screen to reduce surgical difficulty and time. Pelvic and paraaortic lymph node evaluation is a major component of the surgical staging procedure for several gynecologic malignancies including endometrial and ovarian carcinoma.

Step 5 presacral lymph node dissection. The important anatomic landmarks are. Precaval and preaortic lymph nodes are dissected to the level of left renal vein.

Proximalthe left renal vein. 642016 Para-aortic lymphadenectomy reflects complete or near-complete removal of all lymph node tissue within well-defined anatomic boundaries. Distalthe mid-portion of the common iliac arteries.

The presence of variations can not only increase. Beyond the poor prognostic impact of involved paraaortic nodes this knowledge alters further primary tumor management. This article reviews current robotic pelvic and para-aortic lymphadenectomy dissection techniques for endometrial and cervical cancers and discusses the recent integration of pelvic SLN mapping in.

2102021 Paraaortic lymph nodes help drain pelvis organs. We developed an entirely extraperitoneal laparoscopic technique for para-aortic lymph node dissection in a pig model followed by human subject application. Therefore a surgical film focused on the anatomy of para-aortic retroperitoneal spaces and the surgical technique of extraperitoneal para-aortic lymphadenectomy is presented.

And posteriorthe anterior surface of the vertebral bodies. Step 3 left common iliac lymph node dissection. Historically cervical cancer was staged based on clinical findings alone.

Postoperative first flatus time was recorded to evaluate bowel passage and oral intake of the patient was started afterwards. Step 9 vaginal extraction of bags with. Step 7 laterocaval lymph node dissection.

Laparoscopic para-aortic lymph node dissection can be performed through the extraperitoneal or transperitoneal approach.
