Objective: To study the preoperative computed tomography (CT) data of patients with pancreaticoduodenectomy (PD) and to explore the effective of predicting the risk of postoperative pancreatic fistula (POPF). Methods: CT images of patients with PD were analyzed retrospectively from June 2010 to January 2017 in Zhengzhou University of People's Hospital. The pancreas index, pancreatic duct width, pancreas CT value, pancreas-spleen CT value, and pancreas thickness were collected. The relationship between the indicators and the POPF was determined, and the receiver operation characteristic (ROC) curve was calculated and the area under the curve (AUC) was evaluated...

BACKGROUND: Borderline resectable pancreatic cancers infiltrate into adjacent vascular structures to an extent that makes an R0 resection unlikely when pancreatectomy is performed de novo. In a pilot study, Alliance for Clinical Trials in Oncology Trial A021101, the median survival of patients who received chemotherapy and radiation prior to anticipated pancreatectomy was 22 months, and 64% of operations achieved an R0 resection. However, the individual contributions of preoperative chemotherapy and radiation therapy to therapeutic outcome remain poorly defined...

A 74-year-old male was admitted to Departments of Surgery, Toyonaka Municipal Hospital (Osaka, Japan) for treatment of a pancreatic tumor. Contrast enhanced computed tomography (CT) revealed a mass with small cystic lesions in the pancreatic head and body. Fluorodeoxyglucose-positron emission tomography/CT revealed an abnormal uptake of fluorodeoxyglucose, corresponding to the mass lesions. Upper gastrointestinal endoscopy revealed rough mucosa near the opening of the accessory pancreatic duct, and the mucosa biopsy exhibited adenocarcinoma with no mucin observed...

Schwannomas are neurogenic tumors that arise from the neural sheaths of peripheral nerves. These tumors can be located in any area of the human body; the most common locations are the head, neck, trunk and extremities. Pancreatic schwannomas are very rare. Over the past 40 years, only 67 cases of pancreatic schwannomas have been reported in the English literature. Here we present a case of pancreatic schwannoma in a 62-year-old male. The tumor was revealed by ultrasound and computed tomography in the neck and body of the pancreas...

BACKGROUND: Resection surgery for pancreaticobiliary malignancies carries significant morbidity and mortality. Hence, preoperative assessment to exclude unresectable disease is mandatory. CT abdomen is the primary modality for staging of pancreaticobiliary cancers. However, some patients have malignant mediastinal lymphadenopathy (MML), which may be detected on endoscopic ultrasound (EUS) but not on CT scan. METHODS: We prospectively evaluated 75 consecutive patients (median age 54 years: 44 men) with a diagnosis of resectable pancreaticobiliary cancer (carcinoma gallbladder, carcinoma pancreas, cholangiocarcinoma, or periampullary carcinoma) for the presence of MML using EUS by an experienced endosonographer...

Serous cystadenomas of pancreas are unusual cystic tumour. The microcystic forms is more common and its radiological diagnosis is easy. However, the macrocystic unilocular form of serous cystadenoma can be mistaken with other malignant macrocystic lesions of the pancreas. We report the case of a 17 year-old girl, admitted to the National Hospital of Niamey (Niger), with abdominal pain and an unilocular macrocystic serous cystadenoma of pancreas, diagnosed after histological examination of the surgical specimen...

Duodenal gastrointestinal stromal tumors (GISTs) are uncommon. Tumors arising from the first and the second part of the duodenum (DI and DII, respectively) can be wrongly diagnosed as pancreatic mass. We present a case of a 59-year-old woman who came with abdominal pain and severe upper gastrointestinal bleeding (hemoglobin 3.5 g÷dL). A solid, heterogeneously enhancing neoplasm in the head of the pancreas was revealed preoperatively by an abdominal computed tomography scan. A diagnosis of GIST was suggested...

A 45-year-old woman was found to have a pancreatic tumor by abdominal ultrasound performed for a medical check-up. Abdominal contrast-enhanced computed tomography showed a hypovascular tumor measuring 30 mm in diameter in the pancreatic tail. Endoscopic ultrasound-guided fine needle aspiration was performed. An extragastric growing gastrointestinal stromal tumor was thereby diagnosed preoperatively, and surgical resection was planned. Laparoscopic surgery was attempted but conversion to open surgery was necessitated by extensive adhesions, and distal pancreatectomy, splenectomy, and partial gastrectomy were performed...

BACKGROUND: Endoscopic ultrasound guided fine needle aspiration (EUS-FNA) is the procedure of choice to investigate and sample pancreatic masses for the preoperative diagnosis of pancreatic ductal adenocarcinoma (PDAC). The role of (18)fluoro-deoxyglucose positron emission tomography/computed tomography (PET/CT) in PDAC is debated. This study evaluates the role of EUS-FNA as compared to PET/CT in the preoperative evaluation of PDAC. METHODS: Preoperative evaluation by PET/CT and EUS-FNA was performed on 25 patients with pancreatic solid lesions, who underwent a subsequent Whipple procedure or partial pancreatic resection...

An asymptomatic pancreatic tumor was discovered in a 77-year-old man during a medical check-up. An abdominal computed tomography (CT) and magnetic resonance imaging (MRI) revealed a cystic mass containing a septum-like solid portion in the head of the pancreas, measuring 3.5cm in diameter. Additionally, abdominal contrast-enhanced ultrasonography (US) revealed increased flow in the solid portion and a tumor capsule in its early phase. We preoperatively diagnosed the lesion as a cystic-degenerated pancreatic neuroendocrine tumor or solid-pseudopapillary tumor and performed a pancreatoduodenectomy...

Patients with large spontaneous splenorenal shunts (SRSs) prove challenging during liver transplantation (LT), regardless of organizing portal vein (PV) thrombosis. Here, we detail the clinical outcomes of 26 patients who underwent direct ligation of large SRSs during LT. Direct ligation of large SRS was applied in poor portal flow during LT. We performed temporary test clamping of the SRS before direct ligation and applied PV pressure monitoring in patients who showed signs of portal hypertension, such as bowel edema...

In performing pancreaticoduodenectomy (PD) or when conducting clinical trials involving PD procedure, a universal platform for predicting the risk of postoperative pancreatic fistula (POPF) is indispensable. In this article, the most significant imaging studies that focused on the objective preoperative assessment of pancreatic pathologies in association with the occurrence of POPF after PD were reviewed. Several recently developed imaging modalities can objectively predict the occurrence of POPF after PD by assessing the elasticity, fibrosis, and fatty infiltration of the pancreas...
