Prognostic factors for very early recurrence after neoadjuvant treatment and curative resection in pancreatic ductal adenocarcinoma.

Introduction: Very early recurrence in pancreatic ductal adenocarcinoma has been defined as recurrence ≤3 months after resection. Besides others, neoadjuvant treatment is delivered based on the assumption of preoperative eradication of micrometastasis as well as local downstaging. Prognostic factors of very early recurrence after neoadjuvant treatment remain largely unexplored.

Obsidian ASG autologous platelet-rich fibrin matrix for the prevention of postoperative pancreatic fistula following pancreatic resection: study protocol for a feasibility trial at the Medical University of Vienna.

Introduction: Postoperative pancreatic fistula (POPF) is the most frequent complication after partial pancreatectomy, which is by definition associated with clinical consequences requiring changes in postoperative management. Despite numerous scientific efforts, effective procedures to prevent POPF are lacking. Obsidian ASG autologous platelet-rich fibrin matrix has been effectively applied to prevent anastomotic leakage following colorectal surgery.

A systematic review and meta-analysis of morbidity and pancreatic fistula after distal pancreatectomy with versus without prophylactic intra-abdominal drainage.

Background: The omission of a prophylactic intra-abdominal drainage has been under debate in pancreatic surgery due to the high-risk of complications and especially of postoperative pancreatic fistula (POPF). Recently, the second randomized controlled trial (RCT) and two propensity score-matched comparative studies assessing risks and benefits of a no-drainage policy versus prophylactic drainage after distal pancreatectomy (DP) have been published. This systematic review with meta-analysis provides an updated summary of the available evidence on this topic.

Prognostic impact of resection margin status on survival after neoadjuvant treatment for pancreatic cancer: systematic review and meta-analysis.

Background: A greater than 1 mm tumour-free resection margin (R0 >1 mm) is a prognostic factor in upfront-resected pancreatic ductal adenocarcinoma. After neoadjuvant treatment (NAT); however, the prognostic impact of resection margin (R) status remains controversial.

Methods: Randomised and non-randomised studies assessing the association of R status and survival in resected pancreatic ductal adenocarcinoma after NAT were sought by systematic searches of MEDLINE, Web of Science and CENTRAL.

Prevalence and long-term implications of preoperative anemia in patients undergoing elective general surgery: a retrospective cohort study at a university hospital.

Objective: The aim of this retrospective study was to assess the prevalence of anaemia in a cohort of patients undergoing elective general surgery at a university hospital. Furthermore, the authors investigated the influence of anaemia on short-term and long-term postoperative outcome.

Background: Awareness of the negative impact of preoperative anaemia on perioperative morbidity and mortality is rising.

Smoking impairs the effect of neoadjuvant FOLFIRINOX on postresection survival in pancreatic cancer.

Introduction: Smoking plays an important role in carcinogenesis, including pancreatic ductal adenocarcinoma (PDAC). However, little is known about the association between smoking status and prognosis in resected PDAC.

Methods: All patients who underwent resection for PDAC were identified from two prospective institutional databases.

Prognostic significance of mean corpuscular volume in patients with pancreatic ductal adenocarcinoma and multimodal treatment.

Aim Of The Study: Mean corpuscular volume (MCV) has shown mounting evidence as a prognostic indicator in a number of malignancies. The aim of this study was to examine the prognostic potential of pretherapeutic MCV among patients with pancreatic ductal adenocarcinoma (PDAC) who underwent upfront resection or resection after neoadjuvant treatment (NT).

Patients And Methods: Consecutive patients with PDAC who underwent pancreatic resection between 1997 and 2019 were included in this study.

The Revised R Status is an Independent Predictor of Postresection Survival in Pancreatic Cancer After Neoadjuvant Treatment.

Objective: To investigate the oncological outcomes of patients with pancreatic ductal adenocarcinoma (PDAC) who had an R 0 or R 1 resection based on the revised R status (1 mm) after neoadjuvant therapy (NAT).

Background: The revised R status is an independent prognostic factor in upfront-resected PDAC; however, the significance of 1 mm margin clearance after NAT remains controversial.

Methods: Patients undergoing pancreatectomy after NAT for PDAC were identified from 2 prospectively maintained databases.

FOLFIRINOX or Gemcitabine-based Chemotherapy for Borderline Resectable and Locally Advanced Pancreatic Cancer: A Multi-institutional, Patient-Level, Meta-analysis and Systematic Review.

Background: Pancreatic cancer often presents as locally advanced (LAPC) or borderline resectable (BRPC). Neoadjuvant systemic therapy is recommended as initial treatment. It is currently unclear what chemotherapy should be preferred for patients with BRPC or LAPC.

Long-Term Follow-Up after Surgery for Chronic Pancreatitis: A Bicentric Retrospective Experience.

Introduction: The impact of surgery on nutritional status, pancreatic function, and symptoms of patients affected by chronic pancreatitis (CP) has not been unequivocally determined. This study aimed to evaluate clinical follow-up after surgery for CP in an Italian-Austrian population.

Materials And Methods: Patients operated for CP at two high-volume centers between 2000 and 2018 were analyzed.

Surgery for chronic pancreatitis: the comparison of two high-volume centers reveals lack of a uniform operative management.

Purpose: Many aspects of surgical therapy for chronic pancreatitis (CP), including the correct indication and timing, as well as the most appropriate operative techniques, are still a matter of debate in the surgical community and vary widely across different centers. The aim of the present study was to uncover and analyze these differences by comparing the experiences of two specialized surgical units in Italy and Austria.

Methods: All patients operated for CP between 2000 and 2018 at the two centers involved were included in this retrospective analysis.

[Surgery for periampullary pancreatic cancer].

Periampullary neoplasms are a heterogeneous group of different tumor entities arising from the periampullary region, of which pancreatic ductal adenocarcinoma (PDAC) is the most common subgroup with 60-70%. As typical for pancreatic adenocarcinomas, periampullary pancreatic cancer is characterized by an aggressive growth and early systemic progression. Due to the anatomical location in close relationship to the papilla of Vater symptoms occur at an earlier stage of the disease, so that treatment options and prognosis are overall more favorable compared to pancreatic carcinomas at other locations.

The Prognostic Index Independently Predicts Survival in Patients with Pancreatic Ductal Adenocarcinoma Undergoing Resection.

Background: Cancer-related inflammation is associated with tumour proliferation, maintenance and dissemination. It therefore impacts pancreatic cancer survival. The goal of this study was to examine the Prognostic Index (PI) as a prognostic biomarker for survival in patients with pancreatic ductal adenocarcinoma (PDAC).

Sarcopenia and sarcopenic obesity are independent adverse prognostic factors in resectable pancreatic ductal adenocarcinoma.

Background: Incidence and mortality of pancreatic ductal adenocarcinoma (PDAC) are on the rise. Sarcopenia and sarcopenic obesity have proven to be prognostic factors in different types of cancers. In the context of previous findings, we evaluated the impact of body composition in patients undergoing surgery in a national pancreatic center.

Systemic Immune-Inflammation Index (SII) Predicts Poor Survival in Pancreatic Cancer Patients Undergoing Resection.

Background: The systemic immune-inflammation index based on peripheral neutrophil, lymphocyte, and platelet counts has shown a prognostic impact in several malignancies. The aim of this study was to determine the prognostic role of systemic immune-inflammation index in patients with pancreatic ductal adenocarcinoma undergoing resection.

Methods: Consecutive patients who underwent surgical resection at the department of surgery at the Medical University of Vienna between 1995 and 2014 were included into this study.

Long-term Risk of Pancreatic Malignancy in Patients With Branch Duct Intraductal Papillary Mucinous Neoplasm in a Referral Center.

Background & Aims: Little is known about the development of branch duct intraductal papillary mucinous neoplasms (BD-IPMNs). We evaluated long-term outcomes of a large cohort of patients with BD-IPMNs to determine risk of malignancy and define a subset of low-risk BD-IPMNs.

Methods: We performed a retrospective analysis of data from 577 patients with suspected or presumed BD-IPMN under surveillance at the Massachusetts General Hospital.

Preoperative biliary drainage does not increase major complications in pancreaticoduodenectomy: a large single center experience from the Massachusetts General Hospital.

Background: The impact of preoperative biliary drainage (PBD) on perioperative morbidity and mortality in pancreatic surgery is still under debate. The aim of this study was to investigate outcomes of stented vs. non-stented patients undergoing pancreatoduodenectomy (PD).

Discordance Between Perioperative Antibiotic Prophylaxis and Wound Infection Cultures in Patients Undergoing Pancreaticoduodenectomy.

Importance: Wound infections after pancreaticoduodenectomy (PD) are common. The standard antibiotic prophylaxis given to prevent the infections is often a cephalosporin. However, this decision is rarely guided by microbiology data pertinent to PD, particularly in patients with biliary stents.

Intraductal papillary mucinous neoplasms.

Purpose Of Review: Our understanding of intraductal papillary mucinous neoplasm (IPMN) of the pancreas has remarkably grown within the last decade; nonetheless there is still an ongoing controversy if the majority of these potentially malignant neoplasms need to be resected or if observation in a subset is well tolerated.

Recent Findings: Novel cyst fluid biomarkers, like Gnas mutations or mab DAS-1, could play a pivotal role in the distinction of IPMN vs. other cystic lesions, in the sub-classification of IPMN and in the detection of IPMN with high-grade dysplasia or invasive cancer.

Effects of Comorbidities on Outcomes of Patients With Intraductal Papillary Mucinous Neoplasms.

Background & Aims: Intraductal papillary mucinous neoplasms (IPMNs) of the pancreas occur mostly in older individuals. Individual life expectancy and risk of death from other factors must be carefully considered in analyzing the risks that IPMNs pose. We investigated whether there is a subset of patients with IPMNs and a high risk of dying from other causes who would not benefit from pancreatic surgery.

The proteome of postsurgical pancreatic juice.

Objective: This study aimed to evaluate the proteome of the pancreatic juice after pancreatectomy.

Methods: Pancreatic juice samples were obtained during surgery and the postoperative period. Proteins were identified by mass spectrometry-based protein quantification technology and compared with published data of the nonoperated pancreas.

The effect of antecolic versus retrocolic reconstruction on delayed gastric emptying after classic non-pylorus-preserving pancreaticoduodenectomy.

Background: Delayed gastric emptying (DGE) after pancreaticoduodenectomy increases length of hospital stay and costs, and may be influenced by surgical techniques.

Methods: We retrospectively compared 400 patients with antecolic gastrojejunostomy with 400 patients with retrocolic gastrojejunostomy for the occurrence of DGE.

Results: The prevalence of DGE was 15% in the antecolic group and 21% in the retrocolic group (P = .

Not all mixed-type intraductal papillary mucinous neoplasms behave like main-duct lesions: implications of minimal involvement of the main pancreatic duct.

Background: The malignant potential of intraductal mucinous neoplasm of the pancreas (IPMN) is associated closely with main pancreatic duct (MPD) involvement. Because mixed-type IPMN is thought to have the same malignant potential as that of main-duct (MD)-IPMN, resection is recommended; however, the biological nature of mixed-type IPMN with only minimal involvement of MPD (min-mix-IPMN) may be different.

Methods: A prospective database of 404 resected IPMNs was re-reviewed to subclassify mixed-type IPMNs.
