[Robot-assisted Distal Pancreatectomy with En Bloc Celiac Axis Resection (Modified Appleby Procedure) after Neoadjuvant Therapy].

Pancreatic carcinoma in the body and on the left side of the mesentericoportal axis is often only detected in late stages owing to unspecific or even missing clinical symptoms. In approximately 20% of the cases, there is already infiltration of the tumour into the surrounding arteries or veins. Despite locally advanced growth, 30% of patients do not have distant metastases and would potentially qualify for local resection. Arterial resections and vascular reconstruction are associated with an almost 9-fold increase in postoperative mortality compared with resections without vascular reconstruction. The Appleby procedure is a complex surgical technique originally developed for advanced gastric cancer. The technique has been further developed for patients with advanced pancreatic body and tail tumours with infiltration of the coeliac trunk (modified Appleby procedure). The advantage of the procedure is that technically, no reconstruction of the resected arteries is required. This is because a natural internal anastomosis in the pancreatic head between the A. mesenterica superior and the A. hepatica via branches of the A. gastroduodenalis is used to maintain liver perfusion and gastric blood flow. However, the surgical procedure is also associated with high morbidity and mortality, with comparably poor oncological results (R0 rates of approximately 60%). Therefore, the procedure was not recommended until a few years ago, and patients were considered inoperable. With developments in neoadjuvant therapy for pancreatic carcinoma, the Appleby procedure is being performed more frequently, with the goal of improving oncological outcomes in the context of multimodal treatment. With developments in robotics in visceral surgery, the previous limitations of minimally invasive pancreatic surgery can be overcome, and significantly more patients may benefit from the advantages of this minimally invasive surgery, such as faster convalescence. The use of robotic surgical techniques allows the extension of minimally invasive techniques into the field of complex vessel resection and reconstruction. In this video contribution, we describe a robot-assisted modified Appleby procedure using the Da Vinci Xi Surgical System in a patient with advanced pancreatic carcinoma of the pancreatic body, after neoadjuvant therapy.
