Background/Objectives: Neoadjuvant therapy (NAT) is now central to the management of borderline resectable (BRPC) and locally advanced (LAPC) pancreatic ductal adenocarcinoma (PDAC). This narrative review summarizes contemporary evidence and guidelines from a surgical perspective, with emphasis on pretreatment classification, post-NAT selection for exploration, intraoperative vascular strategy, and postoperative management. Methods: We conducted a structured narrative review of randomized and prospective studies, high-quality observational cohorts, and major international guidelines published through 31 July 2025. Results: BRPC and LAPC remain primarily defined by vascular anatomy, but biologic and conditional factors are increasingly integrated into decision-making. NAT is the preferred initial strategy for BRPC and the standard induction approach for LAPC, with resection considered only in carefully selected responders. After NAT, contrast-enhanced CT combined with CA19-9 kinetics remains the core restaging platform, while FDG-PET, diffusion-weighted MRI, radiomics, and circulating biomarkers may serve as adjuncts in equivocal cases. Surgical exploration should be guided by physiologic recovery, the absence of metastatic progression, and multidisciplinary reassessment. Staging laparoscopy remains useful for detecting occult metastatic disease. Intraoperatively, vascular resection should be margin-driven rather than routine, with portal–mesenteric venous resection established in expert centers, whereas arterial resection remains highly selective. Periarterial divestment represents an artery-sparing alternative in selected cases. NAT does not appear to worsen short-term postoperative outcomes, but anticoagulation after venous reconstruction remains non-standardized. Conclusions: NAT has transformed BRPC/LAPC PDAC into a biology-gated, time-sequenced surgical pathway. Standardized reassessment, careful candidate selection, and the centralization of complex vascular procedures are essential to optimize outcomes. Full article

Background: Recent advances in multimodal therapies have increased the potential for resectability of borderline resectable and locally advanced pancreatic ductal adenocarcinoma (PDAC). We herein describe the conservative resection strategy adopted at our institution and the oncological outcomes of patients with PDAC and arterial involvement. Methods: This retrospective single-centre study included patients diagnosed with PDAC and radiologic evidence of arterial involvement who underwent surgical exploration between January 2014 and June 2024. All patients received induction chemotherapy (±radiotherapy). Survival outcomes were analyzed using the Kaplan–Meier and Cox proportional hazards models. Logistic regression analyses were used to identify predictors of resectability and recurrence. Results: A total of 76 patients were included: 59 underwent pancreatic resection with arterial divestment (AD) in case of persistent arterial involvement and 17 were deemed unresectable at laparotomy. Neoadjuvant folfirinox was significantly associated with increased odds of resection (HR = 3.23, 95% CI: 1.59–9.90, p = 0.040). Median overall survival from diagnosis was 33 months (29–39) in resected patients and 26 months (16–29) in non-resected patients (p = 0.0176). Surgical resection and Ca 19,9 normalization after induction therapy were associated with reduced mortality risk (HR = 0.38, 95% CI: 0.19–0.75, p = 0.005 and HR = 0.56, 95% CI: 0.35–0.88, p = 0.014, respectively). Conclusions: Despite a limited sample size and retrospective nature, these findings highlight the value of multimodal strategies in managing PDAC with arterial involvement. AD represents a valuable technique associated with acceptable outcomes in selected patients. Future interventional prospective studies are needed to optimize patient selection and validate the prognostic role of extended surgical procedures. Full article

Vascular resection and reconstruction during pancreatoduodenectomy (PD) have evolved from rare and controversial procedures into essential components of surgical management for selected patients with locally advanced pancreatic ductal adenocarcinoma (PDAC). Venous resection is now widely accepted and routinely performed in high-volume centers, whereas arterial resection and artery-sparing divestment remain selectively applied because of their technical demands and concerns regarding perioperative risk and oncologic benefit. Accumulating contemporary evidence indicates that venous resection can be performed with acceptable safety, with 30-day mortality rates generally ranging from 3% to 5% and median overall survival of approximately 18–26 months when margin-negative (R0) resection is achieved. Arterial resections, most commonly involving the common hepatic, celiac, or superior mesenteric arteries, have been increasingly utilized in highly selected patients, particularly following neoadjuvant therapy, achieving R0 resection rates of approximately 65–75% and median overall survival of 20–28 months. Arterial divestment has emerged as a promising artery-sparing strategy, offering comparable oncologic outcomes with reduced surgical morbidity in appropriately selected cases. Collectively, these advances have expanded the boundaries of resectability in PDAC, enabling surgical intervention in patients previously deemed inoperable. Venous resection is now considered an oncologically sound extension of standard PD, whereas arterial resection and divestment should remain restricted to carefully selected patients demonstrating favorable biologic behavior and response to neoadjuvant therapy. Future progress in this field will likely depend on improved biologic stratification, enhanced intraoperative perfusion assessment, and the integration of hybrid open and endovascular techniques.

Pancreatic ductal adenocarcinoma (PDAC) remains one of the most aggressive malignancies, with overall survival outcomes that have improved only modestly in recent years. Careful preoperative evaluation is essential for defining resectability and planning surgery. Modern imaging modalities, including high-resolution, contrast-enhanced CT, MRI and endoscopic ultrasound, provide a detailed assessment of vascular involvement and allow accurate staging according to various international criteria and consensus statements. In borderline and locally advanced cases, neoadjuvant therapy can aid in downsizing the tumor and increasing the likelihood of achieving negative margin resection (R0), offering long-term survival along with quality of life. When vascular invasion limits resectability, venous resection and reconstruction may permit an R0 resection in patients with borderline resectable disease that is both technically operable and physiologically tolerable for the patient. Arterial resection, however, remains controversial and is rarely justified because of its limited perioperative and survival benefits. Arterial divestment has emerged as an interesting alternative, allowing tumor clearance while avoiding full arterial reconstruction. Vascular reconstructions can be achieved through venorrhapy, end-to-end anastomosis, or segmental replacement using either autologous or synthetic grafts. With the advances in neoadjuvant treatment, the appropriate selection of candidates for vascular resection significantly increases the resectability rate, offering long-term survival along with satisfactory quality of life. In this review, a detailed literature review is performed regarding the best strategies in the diagnosis and surgical management of patients with borderline resectable and locally advanced pancreatic cancer requiring vascular resection.

Pancreaticoduodenectomy (PD) is a complex surgical procedure performed in patients with periampullary tumors located within the pancreatic head, the papilla of Vater, the distal common bile duct, and the duodenum. In advanced tumors, the operative technique involves the need for dissection and divestment of the arteries located within the pancreaticoduodenal field, including the common hepatic artery (CHA) and the proper hepatic artery (PHA) and its branches. The second most important cause of post-PD visceral aneurysms is irritation of the peri-pancreatic arterial wall by pancreatic juice in a postoperative pancreatic fistula (POPF). Hepatic artery pseudoaneurysm (HAP) is a very dangerous condition because it is usually asymptomatic, but it is a rare and potentially lethal pathology because of the high risk of its rupture. Therefore, HAP requires treatment. Currently, selective celiac angiography is the gold-standard diagnostic and therapeutic management for postoperative bleeding and pseudoaneurysm in patients following PD. Open surgery and less invasive endovascular treatment are performed in patients with HAP. Endovascular treatment involves transarterial embolization (TAE) and stent graft implantation. The choice of treatment method depends on the general and local conditions, such as the patient’s hemodynamic stability and arterial anatomy. In patients in whom preservation of the flow within the hepatic artery (to prevent hepatic ischemia complications such as liver infarction, abscess, or failure) is needed, stent graft implantation is the treatment of choice. This article focuses on a review of two common methods for endovascular HAP treatment. In addition, risk factors and diagnostic tools have been described. Full article

Aggressive arterial resection (AR) or total pancreatectomy (TP) in surgical treatment for locally advanced pancreatic cancer (LAPC) had long been discouraged because of their high mortality rate and unsatisfactory long-term outcomes. Recently, new chemotherapy regimens such as FOLFIRINOX or Gemcitabine and nab-paclitaxel have provided more adequate patient selection and local tumor suppression, justifying aggressive local resection. In this review, we investigate the recent reports focusing on arterial resection and total pancreatectomy for LAPC and discuss the rationale of such an aggressive approach in the treatment of PC. AR for LAPCs is divided into three, according to the target vessel. The hepatic artery resection is the simplest one, and the reconstruction methods comprise end-to-end, graft or transposition, and no reconstruction. Celiac axis resection is mainly done with distal pancreatectomy, which allows collateral arterial supply to the liver via the pancreas head. Resection of the superior mesenteric artery is increasingly reported, though its rationale is still controversial. Total pancreatectomy has been re-evaluated as an effective option to balance both the local control and postoperative safety. In conclusion, more and more aggressive pancreatectomy has become justified by the principle of total neoadjuvant therapy. Further technical standardization and optimal neoadjuvant strategy are mandatory for the global dissemination of aggressive pancreatectomies. Full article
