Abstract
The pancreaticobiliary duodenal junction (PBDJ) is the connecting area of the pancreatic duct, bile duct and duodenum. In a broad sense, it refers to a region formed by the head of the pancreas, the pancreatic segment of the common bile duct and the intraduodenal segment, the descending and the horizontal part of the duodenum, and the soft tissue around the pancreatic head. In a narrow sense, it refers to the anatomical Vater ampulla. Due to its complex and variable anatomical features, and the diversity of pathological changes, it is challenging to make an early diagnosis of malignancy at the PBDJ and define the histological type. The unique anatomical structure of this area may be the basis for the occurrence of malignant tumors. Therefore, understanding and subclassifying the anatomical configuration of the PBDJ is of great significance for the prevention and treatment of malignant tumors at their source. The present review comprehensively discusses commonly used imaging techniques and other new technologies for diagnosing malignancy at the PBDJ, offering evidence for physicians and patients to select appropriate examination methods.

Abstract
BACKGROUND To estimate the causal effect of surgery vs chemotherapy on survival in patients with T1-3NxM0 pancreatic cancer in a rigorous framework addressing selection bias and immortal time bias. METHODS We used population-based Danish health-care registries to conduct a cohort study emulating a hypothetical randomized trial to estimate the absolute difference in survival, comparing surgery with chemotherapy. We included pancreatic cancer patients diagnosed during 2008-2021. Exposure was surgery or chemotherapy initiated within a 16-week grace period after diagnosis. At the time of diagnosis, data of each patient were duplicated; one copy was assigned to the surgery protocol, and one copy to the chemotherapy protocol of the hypothetical trial. Copies were censored when the assigned treatment deviated from the observed treatment. To account for informative censoring, uncensored patients were weighted according to confounders. For comparison, we also applied a more conventional analysis using propensity score-based inverse probability weighting. RESULTS We included 1744 patients with a median age of 68 years: 73.6% underwent surgery, and 18.6% had chemotherapy without surgery; 7.8% received no treatment. The 3-year survival was 39.7% (95% confidence interval [CI] = 36.7% to 42.6%) after surgery and 22.7% (95% CI = 17.7% to 28.4%) after chemotherapy, corresponding to an absolute difference of 17.0% (95% CI = 10.8% to 23.1%). In the conventional survival analysis, this difference was 23.0% (95% CI = 17.0% to 29.0%). CONCLUSION Surgery was superior to chemotherapy in achieving long-term survival for pancreatic cancer. The difference comparing surgery and chemotherapy was substantially smaller when using the clone-censor-weight approach than conventional survival analysis.

Long-Term Oncologic Outcome following Duodenum-Preserving Pancreatic Head Resection for Benign Tumors, Cystic Neoplasms, and Neuroendocrine Tumors: Systematic Review and Meta-analysis. Ann Surg Oncol 2024; 31:4637-4653.

Abstract
BACKGROUND Pancreatoduodenectomy (PD) has a considerable surgical risk for complications and late metabolic morbidity. Parenchyma-sparing resection of benign tumors has the potential to cure patients associated with reduced procedure-related short- and long-term complications. MATERIALS AND METHODS Pubmed, Embase, and Cochrane libraries were searched for studies reporting surgery-related complications following PD and duodenum-preserving total (DPPHRt) or partial (DPPHRp) pancreatic head resection for benign tumors. A total of 38 cohort studies that included data from 1262 patients were analyzed. In total, 729 patients underwent DPPHR and 533 PD. RESULTS Concordance between preoperative diagnosis of benign tumors and final histopathology was 90.57% for DPPHR. Cystic and neuroendocrine neoplasms (PNETs) and periampullary tumors (PATs) were observed in 497, 89, and 31 patients, respectively. In total, 34 of 161 (21.1%) patients with intraepithelial papillar mucinous neoplasm exhibited severe dysplasia in the final histopathology. The meta-analysis, when comparing DPPHRt and PD, revealed in-hospital mortality of 1/362 (0.26%) and 8/547 (1.46%) patients, respectively [OR 0.48 (95% CI 0.15-1.58); p = 0.21], and frequency of reoperation of 3.26 % and 6.75%, respectively [OR 0.52 (95% CI 0.28-0.96); p = 0.04]. After a follow-up of 45.8 ± 26.6 months, 14/340 patients with intraductal papillary mucinous neoplasms/mucinous cystic neoplasms (IPMN/MCN, 4.11%) and 2/89 patients with PNET (2.24%) exhibited tumor recurrence. Local recurrence at the resection margin and reoccurrence of tumor growth in the remnant pancreas was comparable after DPPHR or PD [OR 0.94 (95% CI 0.178-5.34); p = 0.96]. CONCLUSIONS DPPHR for benign, premalignant neoplasms provides a cure for patients with low risk of tumor recurrence and significantly fewer early surgery-related complications compared with PD. DPPHR has the potential to replace PD for benign, premalignant cystic and neuroendocrine neoplasms.

Pancreatic head resection for carcinoma of the ampulla vateri - better long-term prognosis, but more postoperative complications. Langenbecks Arch Surg 2024; 409:129. [PMID: 38632147 PMCID: PMC11024026 DOI: 10.1007/s00423-024-03319-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Accepted: 04/10/2024] [Indexed: 04/19/2024]
Abstract
BACKGROUND Pancreatoduodenectomies are complex surgical procedures with a considerable morbidity and mortality even in high-volume centers. However, postoperative morbidity and long-term oncological outcome are not only affected by the surgical procedure itself, but also by the underlying disease. The aim of our study is an analysis of pancreatoduodenectomies for patients with pancreatic ductal adenocarcinoma (PDAC) and ampullary carcinoma (CAMP) concerning postoperative complications and long-term outcome in a tertiary hospital in Germany. METHODS The perioperative and oncological outcome of 109 pancreatic head resections performed for carcinoma of the ampulla vateri was compared to the outcome of 518 pancreatic head resections for pancreatic ductal adenocarcinoma over a 20 year-period from January 2002 until December 2021. All operative procedures were performed at the University Hospital Freiburg, Germany. Patient data was analyzed retrospectively, using a prospectively maintained SPSS database. Propensity score matching was performed to adjust for differences in surgical and reconstruction technique. Primary outcome of our study was long-term overall survival, secondary outcomes were postoperative complications and 30-day postoperative mortality. Postoperative complications like pancreatic fistula (POPF), postpancreatectomy hemorrhage (PPH) and delayed gastric emptying (DGE) were graded following current international definitions. Survival was estimated using Kaplan Meier curves and log-rank tests. A p-value < 0.05 was considered statistically significant. RESULTS Operation time was significantly longer in PDAC patients (432 vs. 391 min, p < 0.001). The rate of portal vein resections was significantly higher in PDAC patients (p < 0.001). In CAMP patients, a pancreatogastrostomy as reconstruction technique was performed more frequently compared to PDAC patients (48.6% vs. 29.9%, p < 0.001) and there was a trend towards more laparoscopic surgeries in CAMP patients (p = 0.051). After propensity score matching, we found no difference in DGE B/C and PPH B/C (p = 0.389; p = 0.517), but a significantly higher rate of clinically relevant pancreatic fistula (CR-POPF) in patients with pancreatoduodenectomies due to ampullary carcinoma (30.7% vs. 16.8%, p < 0.001). Long-term survival was significantly better in CAMP patients (42 vs. 24 months, p = 0.003). CONCLUSION Patients with pancreatoduodenectomies due to ampullary carcinomas showed a better long-term oncological survival, by reason of the better prognosis of this tumor entity. However, these patients often needed a more elaborated postoperative treatment due to the higher rate of clinically relevant pancreatic fistula in this group.

The effect of preoperative biliary drainage on postoperative complications of pancreaticoduodenectomy: a triple center retrospective study. BMC Surg 2022; 22:399.

Abstract
Abstract
Background
Biliary obstruction which is a major complication of pancreas and periampullary tumors could result in cholangitis, coagulopathies, gastrointestinal symptoms, and impaired wound healing. Pancreaticoduodenectomy (PD) is still the standard approach for pancreas resection and imposes high risk of morbidity and mortality to patients. To reduce the high risk of PD and address the biliary obstruction, the use of preoperative biliary stenting was increased. However, available literature doubts its efficiency.
Methods
A total of 147 patients who underwent PD between September 2012, and February 2022, at three medical centers were identified. Patients were grouped based on biliary stent placement. Non-jaundiced patients with and without preoperative biliary drainage (PBD) were compared.
Results
The incidence of overall complications (34.2% versus 45.8%) and mortality (17.8% versus 24.3%) did not differ in the PBD group compared to the no PBD group. There was no difference in complications and mortality in non-jaundiced patients with and without PBD. Patients with drainage duration of > 30 days experienced more overall complications compared to patients with less than 30 days drainage duration (12 (50.0%) and three (15.8%) patients, respectively, p-value = 0.019).
Conclusions
PBD does not significantly increase the post-operative burden on patients who undergo PD. However, we cannot overlook the financial burden that PBD places on the patient and the healthcare system, as well as the difficulties related to endoscopic retrograde cholangiopancreatography (ERCP). Therefore, biliary stenting should not be routinely practiced in the absence of a valid indication, such as severe jaundice, pruritus, cholangitis, delayed surgery for neoadjuvant treatment, or referral to a tertiary facility.

Abstract
ZusammenfassungDas Ampullenkarzinom stellt eine seltene, jedoch in seiner Inzidenz steigende Entität gastrointestinaler Tumoren dar. Aufgrund der anatomischen Lokalisation führt es vergleichsweise früh im
Erkrankungsprozess zu einer biliären Gangobstruktion, wodurch eine schnellere Diagnosestellung erleichtert und eine bessere Prognose bedingt werden. Adenome der Ampulla hepatopancreatica und
der Papilla duodeni major stellen Vorläuferläsionen des Ampullenkarzinoms dar und besitzen ein 30–40%iges Risiko zur malignen Transformation. Diese Entartungstendenz begründet die
Notwendigkeit zur vollständigen/kompletten Abtragung im Rahmen der endoskopischen Therapie. Der Erfolg der endoskopischen Papillektomie wird durch eine Ausdehnung des Befundes in den
Pankreashauptgang oder Ductus choledochus erschwert. Endoskopisch nicht sanierbare Adenome und Ampullenkarzinome stellen Indikationen für chirurgische Therapieverfahren dar. Grundsätzlich
sollte für benigne Befunde die transduodenale Papillenresektion bervorzugt werden, für maligne Befunde stellt die Pankreaskopfresektion mit systematischer Lymphadenektomie und
Level-II-Dissektion des Mesopankreas die onkologisch korrekte Operation dar. Prognostische Faktoren beim Ampullenkarzinom sind: der pankreatobiliäre Subtyp, eine Lymphknoteninfiltration und
eine Perineuralscheideninvasion. Die Differenzierung in histopathologische Subtypen gewinnt zunehmend in der Indikationsstellung zur Systemtherapie an Bedeutung. Der Einsatz der
neoadjuvanten und adjuvanten Therapie für das Ampullenkarzinom konnte bisher nicht klar definiert werden. Jedoch scheinen Patienten mit dem pankreatobiliären Subtyp oder anderen
prognoselimitierenden Faktoren von einer adjuvanten Therapie zu profitieren. Zukünftige Studien werden zur zielgerichteten Therapiefestlegung benötigt.

Abstract
BACKGROUND Endoscopically unresectable adenomas and carcinomas of the greater duodenal papilla and ampulla of the bile duct necessitate surgical resection. The surgical techniques need to be adapted to local tumor expansion and patterns of infiltrative growth. OBJECTIVE Based on the current scientific data and developments this article provides an overview of indications for surgical resection, surgical strategies and dissection techniques for ampullary tumors. MATERIAL AND METHODS A review of the literature addressing surgical management of ampullary neoplasms was performed. Current evidence and recommendations were summarized. RESULTS AND CONCLUSION Ampullary neoplasms can originate from intestinal or pancreatobiliary epithelial cells. Differentiating these histopathological subtypes is of crucial relevance concerning therapeutic strategy and prognosis in ampullary adenocarcinoma. All ampullary adenomas carry a risk of malignant transformation and therefore justify resection. Endoscopic papillectomy, surgical transduodenal ampullectomy and partial pancreatoduodenectomy are suitable resection techniques for ampullary adenoma. The selection of the procedure depends on intraductal tumor extension, tumor size and degree of dysplasia. Ampullary carcinoma is managed by upfront pancreatoduodenectomy comprising systematic lymph node dissection and level II dissection of the mesopancreas. Lymph node status and perineural sheath invasion are key prognostic factors concerning overall survival.

Abstract
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. Nevertheless, the principles of treatment for periampullary pancreatic cancer are not substantially different from the standards for pancreatic cancer at other locations. A potentially curative approach for non-metastatic periampullary pancreatic cancer is a multimodal therapy concept, which includes partial pancreatoduodenectomy as a radical oncological resection in combination with a systemic adjuvant chemotherapy. As a result, long-term survival can be achieved in patients with favorable prognostic factors. In addition, with the continous development of surgery and systemic treatment potentially curative treatment concepts for advanced initially nonresectable tumors were also established, after completion of neoadjuvant treatment. This article presents the current surgical principles of a radical oncological resection for periampullary pancreatic cancer in the context of a multimodal treatment concept with an outlook for future developments of treatment.

Abstract
The surgical treatment of pancreatic cancer (PDAC) has seen sweeping changes during the past 5 decades. Up to the middle of the 20th century resection rates were below 5%, but the numbers of curative resections for PDAC are now continuously increasing due to improved neoadjuvant treatment concepts as well as progress in surgical techniques and perioperative management. During the same period, mortality rates after pancreatic surgery have decreased considerably and are now less than 5%. One of the most important cornerstones of reduced mortality has been the concentration of PDAC surgery in specialized centers. In addition, the management of postoperative complications has improved greatly as a result of optimized interdisciplinary teamwork. Adjuvant chemotherapy has become the reference treatment in resected PDAC, achieving significantly prolonged survival. Moreover, the concept of borderline resectable PDAC has emerged to characterize tumors with increased risk for tumor-positive resection margins or worse outcome. The best treatment strategy for borderline resectable PDAC is currently under debate, whereas neoadjuvant therapy has become established as a beneficial treatment option for patients with locally advanced PDAC, enabling conversion surgery in up to 60% of cases. This review article summarizes the principal changes in PDAC surgery during the past 50 years.
