Successful conversion surgery of distal pancreatectomy with celiac axis resection (DP-CAR) with double arterial reconstruction using saphenous vein grafting for locally advanced pancreatic cancer: a case report

Modified Appleby procedure for locally advanced pancreatic carcinoma: A primer for the radiologist

Pancreatic ductal adenocarcinoma (PDAC) is the most prevalent pancreatic neoplasm accounting for more than 90% of pancreatic malignancies. Surgical resection with adequate lymphadenectomy remains the only available curative strategy for patients with PDAC. Despite improvements in both chemotherapy regimen and surgical care, body/neck PDAC still conveys a poor prognosis because of the vicinity of major vascular structures, including celiac trunk, which favors insidious disease spread at the time of diagnosis. Body/neck PDAC involving the celiac trunk is considered locally advanced PDAC in most guidelines and therefore not eligible for upfront resection. However, a more aggressive surgical approach (i.e., distal pancreatectomy with splenectomy and en-bloc celiac trunk resection [DP-CAR]) was recently proposed to offer hope for cure in selected patients with locally advanced body/neck PDAC responsive to induction therapy at the cost of higher morbidity. The so-called "modified Appleby procedure" is highly demanding and requires optimal preoperative staging as well as appropriate patient preparation for surgery (i.e., preoperative arterial embolization). Herein, we review current evidence regarding DP-CAR indications and outcomes as well as the critical role of diagnostic and interventional radiology in patient preparation before DP-CAR, and early identification and management of DP-CAR complications.

Aorta to proper hepatic artery bypass with total pancreatectomy and celiac axis resection (TP-CAR) in a patient with locally advanced pancreas adenocarcinoma

Introduction

Total pancreatectomy with en-bloc celiac axis resection (TP-CAR) and interposition graft placement between the aorta and the proper hepatic artery is a technically demanding, very uncommonly performed operation, even in high-volume pancreatic centers.

Presentation of case

We present, in clinical and technical detail, a patient with locally advanced adenocarcinoma of the pancreatic body and neck involving the celiac and common hepatic arteries and portal vein, who underwent neoadjuvant chemotherapy and radiation with very good response, followed by TP-CAR and aorto-proper hepatic artery bypass using saphenous vein graft. The patient had an uneventful intraoperative and postoperative course, short hospital stay, and histology consistent with a curative resection.

Discussion

TP-CAR with common hepatic artery resection and proper hepatic artery reconstruction in patients with locally advanced pancreatic body cancer after appropriate neoadjuvant therapy can be performed safely and be potentially curative in centers with an established track record in advanced pancreatic surgery involving major peripancreatic vessels.

Conclusion

TP-CAR with proper hepatic artery reconstruction is a rare but potentially curative operation for selected patients with otherwise unresectable pancreatic adenocarcinoma.

•

TP-CAR and aorto-PHA bypass graft: A very rare, technically demanding operation with significant morbidity & mortality

•

This operation may provide curative (R0) resection of an otherwise unresectable cancer

•

Our patient had optimal perioperative outcome and excellent histology result

•

To the best of our knowledge this is the first TP-CAR with aorto-PHA bypass graft case in Greece
