Laparoscopic left adrenalectomy for Conn's disease: virtual reality and exposure for vascular approach

This is a very detailed and didactic video demonstrating laparoscopic left adrenalectomy. All the critical steps are presented clearly and the surgical approach is explained at each stage. All the dissection is performed with only a hook cautery and atraumatic graspers. This is an excellent video for laparoscopic surgeons interested in learning adrenalectomy. Key landmarks in this step are the splenic, adrenal, and renal veins—and the three main arterial pedicles of the latter that supply the left adrenal gland. The steady mobilization of the pancreas with retraction to the left with the spleen allows the authors to identify the renal vein, clear identification of which is essential. Steady dissection of the superior border of the renal vein enables positive identification of the adrenal vein. The authors dissect it circumferentially from the superior border of the renal vein up to the origin of the phrenic vein.

摘要
This is a very detailed and didactic video demonstrating laparoscopic left adrenalectomy. All the critical steps are presented clearly and the surgical approach is explained at each stage. All the dissection is performed with only a hook cautery and atraumatic graspers. This is an excellent video for laparoscopic surgeons interested in learning adrenalectomy.

Key landmarks in this step are the splenic, adrenal, and renal veins—and the three main arterial pedicles of the latter that supply the left adrenal gland. The steady mobilization of the pancreas with retraction to the left with the spleen allows the authors to identify the renal vein, clear identification of which is essential. Steady dissection of the superior border of the renal vein enables positive identification of the adrenal vein. The authors dissect it circumferentially from the superior border of the renal vein up to the origin of the phrenic vein.

3. Anterior rotation of spleno-pancreatic axis 01'10''
The dissection begins with monopolar cautery that allows for a steady coagulation of all the structures put forward. It is performed by dissection of the lienorenal ligament. Its dissection 1cm from the spleen’s posterior border will allow a progressive tilting of the spleen towards the right side of the abdomen. The spleen’s mobilization is an essential step of the dissection as it ensures the retraction of that organ without the need for instruments. The dissection must be led through the plane located posterior to the pancreas. The dissection will open the avascular plane situated between the Gerota’s facia and the posterior fascia of the pancreas. The dissection is steadily carried out caudally to cranially. It will quickly become possible to identify the splenic vein on the posterior fascia of the pancreas and the adrenal gland. However, because the dissection is being led in relation to anatomical landmarks, proper identification of the gland is not necessary. The dissection is continued cranially on the same plane up to the level of the gastric fundus, of the left crus of the diaphragm, and towards the base until complete mobilization of the spleen’s inferior pole and of the pancreas’s posterior fascia. The space between the kidney and the pancreas opens like 2 pages would in a book. The posterior fascia of the pancreas is perfectly identified and the splenic vein constitutes the left anatomical landmark for the dissection plane. The dissection continues in an identical fashion.
7. Control of inferior adrenal artery 09'30''
This allows for correct identification of the inferior adrenal artery that is the only major arterial structure that has not yet been controlled. Dissection is then continued posteriorly between the adrenal gland and the kidney. The objective is to identify the inferior pole of the gland in order to tilt it to the right. The medial internal and external borders of the gland are now mobilized. Dissection is pursued to the inferior corner of the gland in order to isolate, skeletonize the inferior pedicle. Cautery is carried out using a monopolar hook that helps differentiate the small fibrous tracts from the small accessory structures that are progressively cauterized. The tilt of the gland helps to completely mobilize the external and superior border of the gland. Freeing of the inferior border of the gland is done with extreme caution. At the level of the inferior corner of the gland, the origin of the superior polar artery is often found. It should be preserved by all means to avoid renovascular hypertension if divided. In the present case, the superior polar artery is well identified. The origin of the inferior accessory adrenal branch can be controlled by clips and then divided. Dissection is carried out on the posterior inferior aspect of the gland. The gland is cautiously mobilized using peanut swabs. The inferior arterial branch of the adrenal gland is well identified on the posterior aspect of the gland, which is controlled by clips. It is then divided in order to completely tilt the gland. Dissection is continued with the help of a coagulating hook as in the current case, we are using bipolar cautery. A bipolar forceps helps to control all the small residual venous tracts. Monopolar cautery is a simple and safe means used to make sure all the structures have been controlled and coagulated. The gland is totally freed in the abdomen. The dissection plane is controlled to avoid any bleeding.
