    Abstract:
    Background: The modified Appleby procedure has been developed for cancer of the pancreatic body or tail with celiac axis invasion, historically classified as unresectable disease. Post-Appleby resection, the source of arterial blood to the liver is the superior mesenteric artery, which supplies the gastroduodenal artery and ultimately feeds the proper hepatic artery. In cases of inadequate collateralization, preoperative coiling of the common hepatic artery (CHA) or intraoperative reconstruction via an aorto-hepatic bypass has been described. Method: We describe a 74-year-old female with a pancreatic mass that was initially determined to be unresectable. She underwent extensive combination neoadjuvant chemotherapy. A favorable response was evidenced by a decrease in serum CA 19-9 levels. After 7 months, she was restaged and offered a distal pancreatectomy (DP) with the possibility of a modified Appleby procedure due to potential tumor involvement of the proximal CHA. Results: Intraoperatively, tumor was identified along the CHA traveling proximally to the celiac axis. Therefore, a modified Appleby procedure with DP and splenectomy was performed without the need for reconstruction of the CHA. Postoperative specimen pathology showed residual pancreatic ductal adenocarcinoma with marked treatment effects. The pathology confirmed an R0 resection. The patient followed our postpancreatic surgery care pathway. She remains well 7 months postoperatively. Conclusion: A pancreatic body or tail mass encasing the celiac vessels should not be an immediate referral for palliative care. Recent evidence shows that successful R0 resection can be achieved following neoadjuvant therapy. In fact, patients who have undergone a successful modified Appleby procedure show survival outcomes similar to patients with less advanced cancer who underwent standard DP. The modified Appleby procedure used in conjunction with neoadjuvant therapy can achieve complete resection in select patients previously thought to be unresectable.
