Robotic Left Pancreatectomy with Perirenal Tissue Excision and Left Adrenalectomy (Posterior Ramps) for Pancreatic Ductal Adenocarcinoma Abutting the Adrenal Gland.

BACKGROUND

Radical antegrade modular pancreato-splenectomy (RAMPS) has been largely described in left-sided pancreatic cancers.1.J Hepato-Biliary-Pancreat Sci 29:1156-1165 Its prognostic advantage is not clear, although a theoretical improvement in R0 resection rate has been shown.2.J Am Coll Surg 204:244-249 Furthermore, RAMPS is usually carried out without adrenal gland removal, the so-called anterior RAMPS, while extending the resection to the adrenal plane could impair perioperative outcomes.3.HPB 25:311-319 METHODS: A 40 mm pancreatic ductal adenocarcinoma (PDAC) was found in a 70-year-old patient. Tumor infiltrates the adrenal gland and a robotic posterior RAMPS was indicated.

RESULTS

After sectioning the splenic vessels and the pancreatic neck, the dissection was directed vertically in a sagittal plane along the left border of the superior mesenteric artery to identify the left renal vein. Our dissection plane was then directed on a caudo-cranial axis, after identification of the left renal artery and below the adrenal gland. The resection was also delimitated medially by the left borders of the superior mesenteric artery and the aorta, and posteriorly by the renal parenchyma. Postoperative course was marked by a biochemical leak. The patient was discharged on postoperative day (POD) 5 and the drain removed at POD 18. Pathological examination confirmed a pT2N2 PDAC with negative margins, with 4/18 positive nodes.

CONCLUSIONS

The robotic platform is routinely employed in pancreatic surgery. Thanks to its increased degree of movement, its dexterity, and the magnification, this approach can help surgeons with vascular identification and control, in performing extended lymphadenectomies, and finding the correct planes of dissection. All these elements are crucial in a well-performed posterior RAMPS.
