Based on the BJS lecture at the 21st Annual Meeting of the European Surgical Association, Athens, Greece, April 2014 Published online 21 August 2014 in Wiley Online Library (www.bjs.co.uk). DOI: 10.1002/bjs.9618

Hepatobiliary and pancreatic malignancies frequently involve major vessels such as the inferior vena cava (IVC), hepatic vein, portal vein and foregut arteries, especially the hepatic artery. Tumours involving these structures are often considered unresectable and the patients incurable. Early efforts to include vascular resections as part of hepatectomy and pancreatectomy were associated with increased surgical morbidity and mortality, but recent studies from high-volume centres have shown that combined vascular resections can be undertaken safely with acceptable morbidity and mortality. In turn, this might lead to better outcomes in selected patients. The retrohepatic IVC may be involved by direct invasion in the context of hepatic metastases, intrahepatic cholangiocarcinoma and gallbladder carcinoma. Hepatocellular carcinoma is often associated with intracaval extension of tumour thrombus. Surgical resection of hepatic metastases involving the IVC was reported in 16 patients from Chiba University in 19991 when surgical morbidity and mortality rates were 25 and 6 per cent respectively, with a 5-year survival rate of 27 per cent. In the past few years, European series from Leeds2 and Paris3 have reported IVC resections combined with hepatectomy, with surgical mortality rates between 11 and 14 per cent, and a 5-year survival rate approaching 40 per cent. In a series of 60 patients undergoing combined IVC resections with hepatectomy, including ex vivo © 2014 BJS Society Ltd Published by John Wiley & Sons Ltd

procedures in six, Hemming and colleagues4 had a surgical mortality rate of 8 per cent with 35 per cent 5year survival. Replacement of the cava may be necessary after circumferential resection5 in patients who before surgery have poor development of a collateral circulation, when oliguria occurs or if haemodynamic stability cannot be maintained during surgery. Portal vein resection as a component of hepatectomy is sometimes necessary for patients with intrahepatic cholangiocarcinoma, hilar cholangiocarcinoma and gallbladder cancer. The Chiba series reported in 20076 showed that combined vascular resection was performed in 43 of 161 patients with hilar cholangiocarcinoma who underwent surgical resection. Surgical mortality rates were 4 and 8 per cent in the non-vascular resection and portal vein resection groups respectively, but the 5-year survival rate was 25 per cent after portal vein resection. Interestingly, if hepatic artery resection was also needed in an attempt to achieve clear margins, survival was the same as that in patients with unresectable disease. Neuhaus and co-workers7 also reported longterm survival after combined portal vein resection for hilar cholangiocarcinoma with a 5-year survival rate of 58 per cent. On the contrary, Nagino et al.8 reported that hepatectomy with simultaneous resection of the portal vein and hepatic artery for advanced perihilar cholangiocarcinoma resulted in favourable long-term outcomes with acceptable mortality. However, most publications suggest that surgical

mortality rates lie between 2 and 15 per cent, but with a beneficial effect on long-term survival in patients with hilar cholangiocarcinoma. A systematic review and meta-analysis9 of the role of vascular resection in the treatment of hilar cholangiocarcinoma demonstrated that increased morbidity and mortality was due mainly to the addition of hepatic artery resection compared with portal vein resection alone. This review also showed that routine vascular resection did not always improve negative resection margin rates and had no impact on long-term survival. From this point of view, portal vein resection should not be undertaken routinely and done only where there is suspicion of cancer invasion. Combined hepatic arterial resection results in higher morbidity and mortality with no proven survival benefit and should therefore be performed in select patients. Portal vein resection as part of pancreatectomy is now widely regarded as a safe and feasible procedure with acceptable morbidity and mortality rates. Combined portal vein resection with pancreatectomy should be considered where there is a suspicion of invasion of the portal vein to achieve clear resection margins on the basis of preoperative imaging rather than making the decision purely on operative findings. Unlike the situation with hepatic resections, combined arterial resections involving the coeliac axis, at least in the context of distal pancreatectomy, have been reported without a marked increase in surgical mortality.

coeliac axis resection resulted in a high rate of complete resection and favourable prognosis (estimated overall 5-year survival rate 42 per cent) in selected patients with locally advanced pancreatic body cancer10,11 . Arterial resections involving the coeliac artery and its major branches, as well as multivisceral ex vivo surgery for tumours involving coeliac and superior mesenteric arteries, may be reasonable options for locally invasive tumours with low metastatic potential, such as sarcomas, as reported by the Miami group12 recently. A variety of substitutes for venous reconstruction have been reported. Jugular, external iliac vein, great saphenous vein, left renal and umbilical veins, as well as synthetic grafts have all been used for portal vein reconstruction. As many of these resections may involve contaminated bile and because postoperative infectious complications occur frequently, synthetic grafts are probably best avoided. The clinical usefulness of a left renal vein graft for reconstruction of the portal vein was first reported from Chiba in 199513 . No obvious left kidney dysfunction has been found after the harvest of left renal vein graft at this centre14 . Other groups have also used this graft successfully. The technique has a number of advantages over other substitutes. The left renal vein is obtained from the same operative field without an additional skin incision. It is harvested quickly and easily, usually taking only 5–10 min. The calibre of the vein is often a suitable match for the portal vein to be reconstructed. The patency rate in an experience of 35 patients using a left renal vein graft for portal vein reconstruction was 100 per cent, even at long-term followup14 . Synthetic graft reconstruction after portal vein resection in pancreaticoduodenectomy was reported recently in a multicentre analysis15 . © 2014 BJS Society Ltd Published by John Wiley & Sons Ltd

Among 36 procedures, the overall graft patency rate was 76 per cent, and portal vein thrombosis within 30 days after surgery occurred in 9⋅1 per cent. It would seem that a synthetic graft should not be selected as a portal vein substitute if an autogenous vein graft is available. An alternative approach is the use of a synthetic graft as an intraoperative temporary portal vein shunt, followed by its removal after tumour excision combined with portal vein resection16 . Combined vascular resection during hepatobiliary and pancreatic cancer resections can expand the indications for surgery. This might lead to a survival benefit for some patients with locally advanced tumours and no evidence of distant metastases. In view of the complication rates, these procedures should probably be restricted to carefully selected patients at high-volume centres.
