Computed tomography-based diagnostics might be insufficient in the determination of pancreatic cancer unresectability.

Aim: To inquire into a question of an overestimation of arterial involvement in patients with pancreatic cancer (PC).

Methods: Radiology data were compared with the findings from 51 standard, 58 extended and 17 total pancreaticoduodenectomies; 9 distal resections with celiac artery (CA) excision; and 28 palliations for PC. The survival of 11 patients with controversial computed tomography (CT) and endoscopic ultrasound data with regard to arterial invasion, after R0/R1 procedures (false-positive CT results, Group A), was compared to survival after eight R2 resections (false-negative CT results, Group B) and after 12 bypass procedures for locally advanced cancer (true-positive CT results, Group C).

Liver blood supply after a modified Appleby procedure in classical and aberrant arterial anatomy.

Reported here are two cases of a modified Appleby operation for borderline resectable ductal adenocarcinoma of the pancreatic body, in one of which a R0 distal resection was attended to by excision, not only of the celiac axis, but also of the common and left hepatic arteries in the presence of arterial anatomic variation Michels, type VIIIb. The possibility and avenues of the maintenance of the blood supply to the left hepatic lobe after surgical aggression of this kind are demonstrated employing computed tomography (CT) and 3-D CT angiography. Furthermore, both cases highlight all important worrisome aspects of pancreatic cancer resectability prediction.

Extensive multiarterial resection attending total duodenopancreatectomy and adrenalectomy for MEN-1-associated neuroendocrine carcinomas.

Pancreatic neuroendocrine tumors (PNTs) are relatively uncommon although these neoplasms have been noted to grow in occurrence in recent decades. Surgical removal of locally advanced PNTs involving major vessels and adjacent organs is warranted by reason of an appreciably more favorable prognosis as compared to exocrine pancreas cancer. We are reporting a case of successful multi-organ resection combined with a wide excision of the superior mesenteric, common, proper, left and right hepatic arteries (in the presence of the hepatomesenteric trunk variant of aberrant arterial anatomy) for multifocal PNTs in the setting of multiple neuroendocrine neoplasia type 1 syndrome.
