Vascular Resections in Association With Pancreatic Resections for Locally Advanced Pancreatic Cancer

In Vivo, 2022

Background/Aim: Locally advanced pancreatic cancer has been considered for a long period of time as an unresectable lesion and therefore, all patients have been traditionally addressed to the oncological services for palliative purposes. However, due to the wide usage of newer oncological agents in association with improved surgical techniques, radical surgical procedures became feasible. The aim of this study was to present the different surgical procedures that were performed in locally advanced pancreatic cancer patients in order to achieve radical resections. Patients and Methods: Between 2019 and 2020, six cases were submitted to pancreatic and vascular resections in Fundeni Clinical Hospital. Results: In all cases, surgery with curative intent was attempted; portal vein resection was performed in five cases, whereas arterial resection was performed in three cases. Reconstruction was performed by direct re-anastomosis, by placing cadaveric or synthetic grafts. The postoperative outcomes were favourable in all cases. Conclusion: Vascular resections can be safely associated with pancreatic resections in cases presenting locally advanced pancreatic lesions, with acceptable morbidity rates. Although the procedure of pancreatic head resection en bloc with duodenal resection has been suggested early during the nineteenth century, being proposed by Trendelenburg in 1882, Codvilla in 1898, Kausch in 1909, Hirschel in 1914 and Tenani in 1922, it has been standardised and defined by Allan Whipple in 1935 (1, 2). At that moment, the rates of intraoperative and postoperative complications were significant and therefore, certain surgeons considered that these procedures should be rather abandoned because the risks were higher than the benefits (3-5). During the following decades, improvement in the field of surgery and perioperative care leaded to a significant improvement in the long-term outcomes and encouraged surgeons worldwide to continue performing this procedure (6, 7). When it comes to vascular resections as part of the oncological abdominal surgical procedures, the first such resection was imagined by Appleby in 1953 and consisted of celiac axis resection in 1001 This article is freely accessible online.

En Bloc Vascular Resection for Locally Advanced Pancreatic Malignancies Infiltrating Major Blood Vessels

Annals of Surgery, 2008

To assess in-hospital complication rates and survival duration after en bloc vascular resection (VR) for infiltration of pancreatic malignancies in major vessels. Methods: Between 1994 and 2005, 585 patients underwent potentially curative pancreatic resection without adjuvant chemotherapy. Four hundred forty-nine patients (77%) underwent standard oncologic resection (VRϪ), whereas 136 (23%) received VR (VRϩ). For calculation of in-hospital morbidity and mortality rates, all 136 patients who underwent VR were considered. In contrast, for survival analysis, only pancreatic adenocarcinoma patients (n ϭ 100) were included. Results: One hundred twenty-eight VRϩ patients underwent portal or superior mesenteric vein resection and 13 hepatic artery (HA) or superior mesenteric artery (SMA) resection. In 5 patients, synchronous VR addressing both the mesenterico-portal axis and either the HA or SMA was performed. In-hospital morbidity and mortality rates of VRϪ patients (39.7%/4.0%) nearly equaled that of VRϩ patients (40.3%/3.7%). From the 100 patients with pancreatic adenocarcinoma, histopathology confirmed "true" vascular invasion in 77 patients. Twenty-three patients had peritumoral inflammation, mimicking tumor invasion. Median survival was 15 months (11.2-18.8) in patients with histopathologic proven vascular invasion and 16 months (14.0 -17.9) in those without (P ϭ 0.86). Two-year survival probabilities were 36% (without) versus 34% (with vascular invasion; P ϭ 0.9). Among VRϩ patients with histopathologically evidenced vascular invasion, 19 survived longer than 30 months, and 6 were still alive 5 years after surgery. Multivariate modeling identified nodal involvement (N1) and poor grading (G3) as the only predictors of decreased survival. Evidence of vascular invasion had no adverse impact on survival. Conclusion: Postoperative morbidity and mortality rates after en bloc VR are comparable with "standard" pancreatectomy proce-dures. Median survival of 15 months in patients with vascular invasion is superior to that of patients who undergo palliative therapy and nearly equals that of patients who are not in need for VR.

Vascular Resection in Pancreatic Cancer

Indian Journal of Surgery, 2015

Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive malignant tumors and represents the fifth most common cause of cancer-related deaths. It is associated with a poor prognosis, likely due to the tendency of the tumor for early local and distant spread. One of the major obstacles of effectively treating PDAC is the often late diagnosis. Among all options currently available for PDAC, surgical resection offers the only potential cure with 5-year survival rate of approximately 15-20 %. However, in the absence of metastatic disease, which precludes resection, assessment of vascular invasion is an important parameter for determining resectability for pancreatic cancer. The vascular involvement in patients with pancreatic carcinoma ranges between 21 and 64 %. Historically, vascular involvement has been considered a contraindication to resective cure. Meanwhile, the surgical approach of pancreatoduodenectomy (PD) combined with vascular resection and reconstruction has been widely applied in clinical practice to remove the tumor completely. Therefore, vascular invasion is no longer a surgical contraindication and the rate of surgical resection has greatly increased. Moreover, PD combined with vascular resection can account for 20 to 25 % of the total cases of PD surgery in a number of the larger pancreas treatment centers. The aim of this review is to provide an overview of management and outcome of vascular resection in PDAC surgery.

Surgical Treatment and Complications of Treating Pancreatic Tumor

Medical Archives, 2011

and Herzegovina 4 p ancreatic tumor is one with the worst prognosis of all cancers, and the tenth most frequent cancer in Europe, making the 3% of all cancers affecting both sexes. Most patients seek treatment when the disease is in its advanced stage and the level for possible resectability is low. Late presentation of the disease is responsible for the short survival period of 6 months and a five-year survival of 0.4 to 5% of patients. At the Clinic for Surgery in Tuzla during period from January 1st 1996, to January 1st 2011, a total of 127 resection surgeries were performed due to malignant tumors. The goal of this study was to show that adequate assessment of operability, proper surgical strategy and modern techniques of creating anastomoses reduces morbidity and mortality, results in fewer postoperative complications and contributes to better surgical results. In our study sample the most common place of tumor location was the head of pancreas, in 69 (59.7%) patients. Men develop this type of cancer more often than women in the ratio of 2:1, while the median age of patients was 62 years. We faced postoperative complications in 37 (29.1%) patients, pancreatic fistula being the most prevalent complication, occurring in 16 (12.6%) patients. Overall early and late postoperative mortality was observed in 12 (9.8%) patients. Conclusion: Patients with chronic and hereditary pancreatitis are at a higher risk for developing pancreatic cancer and should be screened for the purpose of early diagnosis. The staging of pancreatic cancer has improved, with the accuracy of 85-90%. Postoperative complications, morbidity, and mortality are significantly reduced (p<0.05) if the standardized operational procedure is applied and if modern techniques are used to create pancreaticojejunal anastomosis as the anastomosis carrying the highest risk.

Intraoperative Pancreatoscopy: A Valuable Tool for Pancreatic Surgeons?

Journal of Gastrointestinal Surgery, 2014

Effective treatment of pancreatic pathology relies on both preoperative and intraoperative decision making. Traditionally, the use of preoperative imaging and endoscopic modalities, in combination with intraoperative findings and pathologic evaluation, has guided the surgeons to perform the correct operative procedure. We hypothesize that the intraoperative use of pancreatoscopy (fiberoptic endoscopy of the pancreatic duct) is a valuable adjunct in selected cases to facilitate the performance of the appropriate definitive surgical treatment. We queried our IRB-approved, prospectively maintained the pancreatic surgery database identifying the uses of intraoperative pancreatoscopy in all pancreatic resections at our institution from 2005-2012. Operative notes, pathology reports, and perioperative outcomes were evaluated. During the study period, 1,016 pancreatic resections were performed at our institution. Twenty-three cases during this period included the use of intraoperative pancreatoscopy. Eighteen (78 %) of these operations were performed for presumed main duct intraductal papillary mucinous neoplasm. In five cases (22 %), the surgical resection was extended secondary to the intraoperative pancreatoscopy findings. Appropriate surgical treatment of the pancreatic lesions can be challenging in the face of preoperative imaging limitations. The selective use of intraoperative fiberoptic endoscopy to evaluate the pancreatic duct appears to help to enable the surgeon to better perform the appropriate resection and optimal treatment.

Middle-preserving pancreatectomy: an interesting procedure for pancreas-sparing resection

JOP : Journal of the pancreas, 2010

CONTEXT Total pancreatectomy is the treatment of choice for multicentric diseases involving the head and the body-tail of the pancreas. Middle-preserving pancreatectomy is a recently reported alternative procedure when the pancreatic body is spared from disease. We report on the successful preservation of the pancreatic body in a patient harboring a multicentric intraductal papillary mucinous neoplasia (IPMN). CASE REPORT A multicentric IPMN was diagnosed in a 59-year-old man. A standard pylorus preserving pancreaticoduodenectomy was performed, followed by a spleen-preserving distal pancreatectomy. The splenic vessels were carefully preserved. The residual 5 cm of the pancreatic body were anastomosed to the jejunum after verifying that the resection line on both sides was negative at frozen section examination. The postoperative course was complicated by transient peritoneal bleeding managed with angiographic embolization of the splenic artery. A borderline mixed type IPMN of the he...

Middle Pancreatectomy

Annals of Surgery, 2007

Objective: To evaluate the indications, perioperative, and long-term outcomes of a large cohort of patients who underwent middle pancreatectomy (MP). Summary Background Data: MP is a parenchyma-sparing technique aimed to reduce the risk of postoperative exocrine and endocrine insufficiency. Reported outcomes after MP are conflicting. Methods: Patients who underwent MP between 1990 and 2005 at the Massachusetts General Hospital and at the University of Verona were identified. The outcomes after MP were compared with a control group that underwent extended left pancreatectomy (ELP) for neoplasms in the mid pancreas. Results: A total of 100 patients underwent MP. The most common indications were neuroendocrine neoplasms, serous cystadenoma, and branch-duct IPMNs. Comparison with 45 ELP showed that intraoperative blood loss and transfusions were significantly higher for ELP. The 2 groups showed no differences in overall morbidity, abdominal complications, overall pancreatic fistula, and grade B/C pancreatic fistula rate (17% in MP and 13% in ELP), but the mean hospital-stay was longer for MP patients (P ϭ 0.005). Mortality was zero. In the MP group, 5 patients affected by IPMNs had positive resection margins and 3 had recurrence. After a median follow-up of 54 months, incidence of new endocrine and exocrine insufficiency were significantly higher in the ELP group (4% vs. 38%, P ϭ 0.0001 and 5% vs. 15.6%, P ϭ 0.039, respectively). Conclusions: MP is a safe and effective procedure for treatment of benign and low-grade malignant neoplasms of the mid pancreas and is associated with a low risk of development of exocrine and endocrine insufficiency. MP should be avoided in patients affected by main-duct IPMN.

General Aspects of Surgical Treatment of Pancreatic Cancer

Digestive Surgery, 1999

Background: Different results and opinions exist concerning the use of a standard or an extended lymphadenectomy, and about the indications for portal vein resection in the surgical treatment of pancreatic cancer. The site of recurrence of pancreatic cancer may help to define the usefulness of different treatments in avoiding local and/or distant recurrences. Methods: From personal experience and a literature review, 841 patients who underwent portal vein resection were collected, and 29 papers reporting the results of extended lymphadenectomy in the surgical treatment of pancreatic cancer were analyzed. A review of the site of relapse according to the surgical treatment, with or without various adjuvant treatments, was performed. Personal experience on survival rate according to the site of relapse (local, distant, local and distant) is also reported. Results: Portal vein resection has been performed without a significant increase in morbidity and mortality rate in a large number of patients. However, its usefulness for increasing the resectability rate and the long-term survival has yet to be established. Extended lymphadenectomy does not increase the morbidity and mortality rate, but conflicting results on long-term survival have been reported. Distant metastases, undetectable by the radiologist and the surgeon, usually kill more than 40% of the resected patients within 12 months. Only lymph node-positive patients with limited undetectable distant metastases seem to benefit from an extended lymphadenectomy. Although many data are lacking, the incidence of the different sites of relapse is the same whatever the surgical and/or adjuvant treatment performed. Overall survival and disease-free survival rate are not affected by the site of relapse. A significantly worse survival rate was observed after the radiological detection of local and distant metastasis than after an only local or only distant metastasis. Conclusion: Portal vein resection and extended lymphadenectomy can be performed without increasing the surgical morbidity and mortality rate. We still have insufficient data to decide which patient can benefit from a more extended procedure. Standardization of operations, terminology, pathological reporting, and follow-up, together with well-designed prospective studies, will help to decide the operation of choice for pancreatic cancer.

International consensus guidelines 2012 for the management of IPMN and MCN of the pancreas

Pancreatology, 2012

The international consensus guidelines for management of intraductal papillary mucinous neoplasm and mucinous cystic neoplasm of the pancreas established in 2006 have increased awareness and improved the management of these entities. During the subsequent 5 years, a considerable amount of information has been added to the literature. Based on a consensus symposium held during the 14th meeting of the International Association of Pancreatology in Fukuoka, Japan, in 2010, the working group has generated new guidelines. Since the levels of evidence for all items addressed in these guidelines are low, being 4 or 5, we still have to designate them "consensus", rather than "evidence-based", guidelines. To simplify the entire guidelines, we have adopted a statement format that differs from the 2006 guidelines, although the headings are similar to the previous guidelines, i.e., classification, investigation, indications for and methods of resection and other treatments, histological aspects, and methods of follow-up. The present guidelines include recent information and recommendations based on our current understanding, and highlight issues that remain controversial and areas where further research is required.

Parenchyma-Sparing Pancreatectomy for Presumed Noninvasive Intraductal Papillary Mucinous Neoplasms of the Pancreas

Annals of Surgery, 2014

Objective: To assess the feasibility and outcomes of parenchyma-sparing pancreatectomy (PSP), including enucleation (EN), resection of uncinate process (RUP), and central pancreatectomy (CP), as an alternative to standard pancreatectomy for presumed noninvasive intraductal papillary and mucinous neoplasms (IPMNs). Background: Pancreaticoduodenectomy and distal pancreatectomy are associated with significant perioperative morbidity, a substantial risk of pancreatic insufficiency, and may overtreat noninvasive IPMNs. Methods: From 1999 to 2011, PSP was attempted in 91 patients with presumed noninvasive IPMNs, after complete preoperative work-up including computed tomography, magnetic resonance imaging, and endoscopic ultrasonography. Intraoperative frozen section examination was routinely performed to assess surgical margins and rule out invasive malignancy. Follow-up included clinical, biochemical, and radiological assessments. Results: Overall PSP was achieved with a feasibility rate of 89% (n = 81), including 44 ENs, 5 RUPs, and 32 CPs. Postoperative mortality rate was 1.3% (n = 1), and overall morbidity was noteworthy (61%; n = 47). Definitive pathological examination confirmed IPMN diagnosis in 95% of patients (n = 77), all except 2 (3%), without invasive component. After a median follow-up of 50 months, both pancreatic endocrine/exocrine functions were preserved in 92% of patients. Ten-year progression-free survival was 76%, and reoperation for recurrence was required in 4% of patients (n = 3). Conclusions: In selected patients, PSP for presumed noninvasive IPMN in experienced hands is highly feasible and avoids inappropriate standard resections for IPMN-mimicking lesions. Early morbidity is greater than that after standard resections but counterbalanced by preservation of pancreatic endocrine/exocrine functions and a low rate of reoperation for tumor recurrence.
