Lymphoepithelial cyst mimicking pancreatic cancer: a case report and literature review.

Surg Case Rep 2021 Apr 29;7(1):108. Epub 2021 Apr 29.

Division of Gastroenterological, Hepato-Biliary-Pancreatic, Transplantation and Pediatric Surgery, Department of Surgery, Shinshu University School of Medicine, 3-1-1 Asahi, Matsumoto, Nagano, 390-8621, Japan.

Rare histological subtype of invasive micropapillary carcinoma in the ampulla of Vater: A case report.

World J Clin Cases 2021 Apr;9(11):2671-2678

Department of Pathology, Kagoshima University Graduate School of Medical and Dental Sciences, Kagoshima 890-8544, Japan.

Extended lymph node resection versus standard resection for pancreatic and periampullary adenocarcinoma.

Cochrane Database Syst Rev 2021 01 20;1:CD011490. Epub 2021 Jan 20.

Department of Visceral and Thoracic Surgery, Cantonal Hospital of Winterthur, Winterthur, Switzerland.

Background: Pancreatic and periampullary adenocarcinomas account for some of the most aggressive malignancies, and the leading causes of cancer-related mortalities. Partial pancreaticoduodenectomy (PD) with negative resection margins is the only potentially curative therapy. The high prevalence of lymph node metastases has led to the hypothesis that wider excision with the removal of more lymphatic tissue could result in an improvement of survival, and higher rates of negative resection margins.

BMC Surg 2020 Dec 1;20(1):307. Epub 2020 Dec 1.

Department of Gastroenterological Surgery and Surgical Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Shikata-cho 2-5-1, Kita-ku, Okayama city, Okayama, 7000914, Japan.

Background: Hemobilia occurs mainly due to iatrogenic factors such as impairment of the right hepatic or cystic artery, and/or common bile duct in hepatobiliary-pancreatic surgery. However, little or no cases with hemobilia from the intra-pancreatic remnant bile duct after bile duct resection (BDR) has been reported. Here, we report a case of massive hemobilia due to the perforation of psuedoaneurysm of the gastroduodenal artery (GDA) to the intra-pancreatic remnant bile duct after hepatectomy with BDR.

Cytokeratin-positive cells in the bone marrow from patients with pancreatic, periampullary malignancy and benign pancreatic disease show no prognostic information.

BMC Cancer 2020 Nov 16;20(1):1107. Epub 2020 Nov 16.

Department of Gastrointestinal Surgery, Oslo University Hospital, Oslo, Norway.

Background: Pancreatic and periampullary carcinoma are aggressive tumours where preoperative assessment is challenging. Disseminated tumour cells (DTC) in the bone marrow (BM) are associated with impaired prognosis in a variety of epithelial cancers. In a cohort of patients with presumed resectable pancreatic and periampullary carcinoma, we evaluated the frequency and the potential prognostic impact of the preoperative presence of DTC, defined as cytokeratin-positive cells detected by immunocytochemistry (ICC).

J Int Med Res 2020 Aug;48(8):300060520947918

Department of Hepatology, The first hospital of Jilin University, Changchun, China.

Mixed adenoneuroendocrine carcinoma (MANEC) is a rare tumour of the gastrointestinal tract with both epithelial and neuroendocrine components. We describe a case of a 57-year-old man who presented with yellow sclera and dark urine.

Role of cholangitis in predicting survival in patients with carcinoma of the ampulla of vater.

Surg Oncol 2020 Dec 11;35:34-38. Epub 2020 Aug 11.

Department of Surgery, Seoul National University Bundang Hospital, Seoul National University College of Medicine, Republic of Korea.

Background: There have been strong suggestions that acute inflammation promotes tumour growth, and has a tendency for increased invasiveness, leading to poor survival after surgery. When cholangitis coexists with ampulla of vater cancer, the patient's prognosis may be influenced by the acute inflammatory status of the bile duct. We evaluated the relationship between the severity of acute cholangitis, preoperative CRP levels and survival. Read More
