Periampullary carcinoma

PURPOSE: Perioperative transfusion is reported to be an independent risk factor not only for postoperative complications but also for early recurrence of periampullary carcinoma after pancreaticoduodenectomy (PD). The purpose of this study was to evaluate the safety and efficacy of ferric carboxymaltose (FCM) in reducing the need for perioperative transfusion in iron deficiency anemia patients scheduled for PD. METHODS: Twenty-two male patients (hemoglobin [Hb] 7 to <13 g/dL) and 18 female patients (Hb 7 to <12 g/dL) were enrolled in the study group and administered FCM 1-3 weeks before PD...

BACKGROUND: Magnetic resonance cholangiopancreatography (MRCP) is a non-invasive imaging modality that has high diagnostic accuracy for a wide range of bile duct and pancreatic duct pathologies. Endoscopic retrograde cholangiopancreatography (ERCP) is still the gold standard for the exploration of the biliopancreatic region. AIM: The aim of the study was to compare the diagnostic accuracy of MRCP with that of ERCP in the diagnosis of bile duct and pancreatic duct pathologies...

BACKGROUND: To assess the image quality feasibility and diagnostic value of zoomed diffusion-weighted imaging (z-EPI DWI) using echo-planar imaging (EPI) compared with conventional DWI (c-EPI DWI) in patients with periampullary disease. METHODS: Thirty-six patients with periampullary carcinomas and fifteen with benign periampullary disease were included in this study. All the subjects underwent MR cholangiopancreatography (MRCP), c-EPI DWI, and z-EPI DWI. Two radiologists independently assessed image quality of the two image sets, including overall image quality and lesion conspicuity...

RATIONALE: Gastric stump carcinoma (GSC) is very exceptional and little known after Whipple procedure, and its diagnosis and treatment are extremely difficult to handle. PATIENT CONCERNS: The patient, a 68-year-old man, visited our hospital's General surgery outpatient clinic complaining of upper abdominal pain that had been bothering him for half a month. The endoscopy revealed lesions in the stomach residual, and the pathological results suggested adenocarcinoma...

BACKGROUND: Mixed neuroendocrine-non-neuroendocrine neoplasms of the ampulla of Vater are rare and heterogenous, making it difficult to achieve a definitive preoperative diagnosis. Herein, we describe a patient in whom a provisional diagnosis of mixed neuroendocrine-non-neuroendocrine neoplasm of the ampulla of Vater was made preoperatively. CASE PRESENTATION: Computed tomography revealed an enhancing periampullary tumor in a 69-year-old man with obstructive jaundice...

BACKGROUND: The role of preoperative biliary drainage (PBD) on obstructive jaundice patients is still controversial. The aim of this retrospective study is to clarify the effect of PBD on postoperative outcomes of pancreaticoduodenectomy (PD) and explore a reasonable PBD strategy for periampullary carcinomas (PAC) patients with obstructive jaundice before surgery. METHODS: A total of 148 patients with obstructive jaundice who underwent PD were enrolled in this research and divided into drainage group and no-drainage group according to whether they received PBD...

The incidence of ampulla of Vater carcinoma, a type of periampullary cancer, has been increasing at an annual percentage rate of 0.9%. However, patients with ampulla of Vater carcinoma have quite different prognoses due to the heterogeneities of the tissue origin of this carcinoma. In addition to TNM staging, histological subtypes and molecular features of ampulla of Vater carcinoma are the key factors for predicting the clinical outcomes of patients. Fortunately, with the development of testing technology, information on the histological subtypes and molecular features of ampulla of Vater carcinoma is increasingly being analyzed in-depth...

RATIONALE AND OBJECTIVES: Magnetic resonance imaging plays an important role in the evaluation of patients with known or suspected periampullary masses. The utilization of volumetric apparent diffusion coefficient (ADC) histogram evaluation for the entire lesion eradicates the potential for subjectivity in the region of interest placement, thus guaranteeing the accuracy of computation and repeatability. PURPOSE: To investigate the value of volumetric ADC histogram analysis in the differentiation of intestinal-type (IPAC) and pancreatobiliary-type periampullary adenocarcinomas (PPAC)...

Background & aim: MicroRNAs associated with the Notch pathway play a critical role in the progression of pancreatic carcinoma. Our aim was to study the clinical significance of miR-107 and NOTCH2 in pancreatic ductal adenocarcinoma (PDAC). Methods: The circulating miR-107 levels in PDAC and controls were determined by qPCR. NOTCH2 protein (target) expression in tissue of PDAC, periampullary carcinoma, chronic pancreatitis and normal pancreatic tissue was assessed by immunohistochemistry. Results: The circulating miR-107 levels were found to be significantly reduced in PDAC as compared with controls...

Genetic and epigenetic alterations of the telomere maintenance machinery like telomere length and telomerase reverse transcriptase (encoded by TERT gene) are reported in several human malignancies. However, there is limited knowledge on the status of the telomere machinery in periampullary carcinomas (PAC) which are rare and heterogeneous groups of cancers arising from different anatomic sites around the ampulla of Vater. In the current study, we investigated the relative telomere length (RTL) and the most frequent genetic and epigenetic alterations in the TERT promoter in PAC and compared it with tumor-adjacent nonpathological duodenum (NDu)...

INTRODUCTION: Acute cholangitis usually complicates biliary obstruction and antibiotic therapy plays a major role, as an adjunct to adequate biliary drainage in cholangitis. The knowledge of bacterial epidemiology in cholangitis will help to choose antibiotic wisely. The aim of the study was to analyze the clinical and bacteriological profile, in acute cholangitis. MATERIALS: We retrospectively analyzed the patients with acute cholangitis admitted under the Department of Gastroenterology, Kalinga Institute of Medical Sciences, Bhubaneswar August 2020 and July 2022...

OBJECTIVES: Perioperative morbidity after pancreatoduodenectomies is still high. One potentially responsible factor is the insertion of bile duct stents before surgery. In our single-center study, we evaluated the influence of preoperative bile duct stenting combined with perioperative antibiotic therapy versus primary surgery in carcinoma patients. METHODS: Clinical data of 973 patients undergoing pancreatoduodenectomy at the University Hospital Freiburg from 2002 to 2018 were explored retrospectively...

Surgical site infections (SSIs) following a pancreaticoduodenectomy have been a significant cause of morbidity and even mortality. A modified sequence of the Whipple procedure, using the COMBILAST technique, may reduce SSIs and the patient's hospital stay. This prospective cohort study included 42 patients undergoing Whipple's pancreaticoduodenectomy for a periampullary malignancy. The modified sequence pancreaticoduodenectomy technique, COMBILAST, was used to estimate the incidence of SSI and explore other advantages...

A 63-year-old male with multiple co-morbidities presented with a diabetic foot infection which was treated surgically. During admission to the hospital, he developed melena and underwent an endoscopic assessment which revealed an incidental finding of an ampullary mass. The histological analysis of the biopsy revealed ampullary carcinoma with mixed intestinal-type and pancreatobiliary-type features. A magnetic resonance imaging (MRI) of the liver with contrast presented the tumor as an ill-defined small soft tissue lesion measuring 8 x 9 mm in the ampullary region, with multiple lymph nodes in the periportal, peripancreatic, and para-aortic regions...

Primary squamous cell carcinoma (SCC) of the periampullary area is exceedingly rare. We report a case of a 45-year-old woman who presented with progressive upper abdominal pain and melena. Laboratory testing revealed an elevated level of carcinoembryonic antigen. Esophagogastroduodenoscopy revealed a very large irregular ulcerated tumor in the periampullary area. Contrast-enhanced computed tomography (CT) of the chest, abdomen, and pelvis, 18 F-fluorodeoxyglucose positron emission tomography/CT, and thin-prep cytologic test excluded metastasis of the primary tumor to the periampullary area from other sites...

RATIONALE: Pseudoprogression has been deemed as a rare clinical phenomenon during the treatment of immune checkpoint inhibitors in patients with advanced cancers, especially in periampullary carcinoma, however, leaving potential molecular mechanism remain unknown. PATIENT CONCERNS: Regular examination after radical pancreaticoduodenectomy because of periampullary carcinoma. DIAGNOSES: Recurrent periampullary carcinoma with metastasis in liver...

RATIONALE AND OBJECTIVES: The aim of this study was to differentiate pancreatobiliary and intestinal type periampullary carcinomas using dynamic contrast MRI and MRCP (Magnetic Resonance Cholangiopancreatography) with diffusion-weighted imaging (DWI) MATERIALS AND METHODS: MRI and MRCP images of 70 patients with pathologically proven periampullary adenocarcinoma were included. MRCP image features, extra-ampullary features, enhancement patterns, and apparent diffusion coefficient (ADC) values derived from b-values of 1000 s/mm² were evaluated by two radiologists independently...

PURPOSE: The aim of this study was to investigate the value of multi-slice computed tomography (MSCT) in preoperatively diagnosing perineural invasion (PNI) of periampullary carcinoma (PAC). METHODS: Of 81 patients pathologically diagnosed as PAC, 73 patients were included. Their clinical documents and preoperative upper abdominal enhanced MSCT images were retrospectively reviewed to analyse clinical characteristics and MSCT features. MSCT features included tumor size, classification of fat tissue around celiac trunk and superior mesenteric artery...

BACKGROUND: The supposed adverse effect of involved resection margin during pancreaticoduodenectomy (PD) for periampullary carcinoma or pancreatic head carcinoma (CaP) on long-term oncological outcomes is still inconclusive. METHODS: This is a retrospective study on periampullary carcinoma undergoing PD. Patients with R0 (margin clear) resection were compared to patients with R1 (microscopically directly involved margin) resection. Patients with gross involved margin (R2 resection) were excluded...

BACKGROUND: Major complications (MCs) after pancreaticoduodenectomy (PD) are a known independent predictor of worse oncologic outcomes. There are limited data on the effect of major complications on long-term outcomes after robotic PD (RPD). The aim of this study is to compare the effect of MC on overall (OS) and disease-free survival (DFS) after RPD and open PD (OPD). METHODS: This is a single-center, retrospective review of a prospectively maintained database of all patients undergoing PD for periampullary cancer including ampullary adenocarcinoma, distal cholangiocarcinoma, and duodenal carcinoma...
