ABSTRACT Major vascular resection performed at the time of pancreaticoduodenectomy (PD) for adenocarcinoma remains controversial. We analyzed all patients who underwent vascular resection (VR) at the time of PD for any histology at a single institution between 1990 and 2002. Preoperative imaging criteria for PD included the absence of tumor extension to the celiac axis or superior mesenteric artery (SMA). Tangential or segmental resection of the superior mesenteric or portal veins was performed when the tumor could not be separated from the vein. As a separate analysis, all patients who underwent PD with VR for pancreatic adenocarcinoma were compared to all patients who underwent standard PD for pancreatic adenocarcinoma. A total of 141 patients underwent VR with PD. Superior mesenteric-portal vein resections included tangential resection with vein patch (n=36), segmental resection with primary anastomosis (n=35), and segmental resection with autologous interposition graft (n=55). Hepatic arterial resections were performed in 10 patients, and resections of the anterior surface of the inferior vena cava were performed in 5 patients. PD was performed for pancreatic adenocarcinoma in 291 patients; standard PD was performed in 181 and VR in 110. Median survival was 23.4 months in the group that required VR and 26.5 months in the group that underwent standard PD (P=0.177). A Cox proportional hazards model was constructed to analyze the effects of potential prognostic factors (VR, tumor size, T stage, N status, margin status) on survival. The need for VR had no impact on survival duration. In conclusion, properly selected patients with adenocarcinoma of the pancreatic head who require VR have a median survival of approximately 2 years, which does not differ from those who undergo standard PD and is superior to historical patients believed to have locally advanced disease treated nonoperatively.

    ABSTRACT: Background To evaluate the predictors for resectability and survival of patients with locally advanced pancreatic cancer (LAPC) treated with gemcitabine-based neoadjuvant therapy (GBNAT). Methods Between May 2003 and Dec 2009, 41 tissue-proved LAPC were treated with GBNAT. The location of pancreatic cancer in the head, body and tail was 17, 18 and 6 patients respectively. The treatment response was evaluated by RECIST criteria. Surgical exploration was based on the response and the clear plan between tumor and celiac artery/superior mesentery artery. Kaplan–Meier analysis and Cox Model were used to calculate the resectability and survival rates. Results Finally, 25 patients received chemotherapy (CT) and 16 patients received concurrent chemoradiation therapy (CRT). The response rate was 51% (21 patients), 2 CR (1 in CT and 1 in CRT) and 19 PR (10 in CT and 9 in CRT). 20 patients (48.8%) were assessed as surgically resectable, in which 17 (41.5%) underwent successful resection with a 17.6% positive-margin rate and 3 failed explorations were pancreatic head cancer for dense adhesion. Two pancreatic neck cancer turned fibrosis only. Patients with surgical intervention had significant actuarial overall survival. Tumor location and post-GBNAT CA199 < 152 were predictors for resectability. Post-GBNAT CA-199 < 152 and post-GBNAT CA-125 < 32.8 were predictors for longer disease progression-free survival. Pre-GBNAT CA-199 < 294, post-GBNAT CA-125 < 32.8, and post-op CEA < 6 were predictors for longer overall survival. Conclusion Tumor location and post-GBNAT CA199 < 152 are predictors for resectability while pre-GBNAT CA-199 < 294, post-GBNAT CA-125 < 32.8, post-GBNAT CA-199 < 152 and post-op CEA < 6 are survival predictors in LAPC patients with GBNAT.

    ABSTRACT: Portal vein (PV) disorders are various, but rare. Here, we report a preduodenal superior mesenteric vein (PDSMV) in a patient who underwent a pancreaticoduodenectomy. A 67-year old woman with familial adenomatosis polyposis was suspicious for cancer of the papilla of vater and scheduled for surgery. Pre-operative diagnostic revealed a PDSMV continuing into the left PV. The splenic vein (SV) continued directly into the right PV without forming ananatomic PV confluence. Eight centimetre of the PDSMV were resected during the pancreaticoduodenectomy and reconnected using a polytetrafluoroethylene prosthesis. On day 1, early graft thrombosis was treated by thrombectomy and change to a larger graft. Pathology confirmed a R0-resection of the adenocarcinoma of the papilla of vater (pTis pN0,G2). At three-month follow-up, the patient was cancer-free and clinically asymptomatic, although, a late graft thrombosis with accompanying newly build venous collaterals passing mesenteric blood to the SV were found. Rare PV disorders like a PDSMV do not contradict pancreatic surgery, but should be treated in experienced centres. Skills of SMV/PV reconstruction and its peri-operative management might be beneficial for successful outcome. Despite late graft thrombosis no clinical disadvantage occurred most likely due to preservation of the SV and of potential venous collateral pathways. Extended surgical procedures like a pancreaticoduodenectomy are realisable in patients with PV disorders, but require awareness, adequate radiological interpretation and specific surgical experience for secure treatment.

    ABSTRACT: Introduction The value of extended resection (portal vein, multivisceral) in patients with pancreatic adenocarcinoma (PDAC) is not well defined. We analyzed the outcome after standard resection (standard pancreaticoduodenectomy (SPR)), additional portal vein (PV) and multivisceral (MV) resection in PDAC patients. Methods Clinicopathologic, perioperative, and survival data of patients undergoing pancreatic head resection (PHR) for PDAC 1994–2014 were reviewed from a prospective database. Results Three hundred fifty nine patients had PHR for PDAC: 208 (58 %) underwent SPR, 131 (36 %) additional PV, and 20 (6 %) MV. The postoperative complication rate in MV (65 %) was slightly higher than in PV (56 %) or SPR (50 %; p = 0.32). MV patients had higher in-hospital mortality (10 %) than SPR (3.8 %) and PV (1.5 %) patients (p = 0.12). Nodal status was comparable, whereas more patients in PV and MV had final R0 resection (p = 0.02). Five-year survival was 7 % after MV versus 17 % in patients without MV (p = 0.07). Multivariate survival analysis identified resection margin, nodal disease, blood transfusions, and MV are set as independent risk factors for overall survival. Conclusion Multivisceral pancreatic head resections for PDAC are associated with increased perioperative morbidity and mortality, without improving oncologic outcome. Portal vein resection can be performed safely to reach R0 resection and its survival benefits.
