Study Protocol of the ESAP Study: Endoscopic Papillectomy vs. Surgical Ampullectomy vs. Pancreaticoduodenectomy for Ampullary Neoplasm-A Pancreas2000/EPC Study.

Front Med (Lausanne) 2020 6;7:152. Epub 2020 May 6.

Department of Digestive, Hepatobiliary and Endocrine Surgery, Paris Descartes University, Cochin Hospital, Paris, France.

Lesions of the Ampulla of Vater are a rare condition and represent <10% of peri-ampullary neoplasms. Nevertheless, ampullary adenomas have the potential for malignant transformation to ampullary carcinomas by an adenoma-to-carcinoma sequence. Thus, adequate patient selection and complete resection (R0) of non-invasive ampullary lesions either by endoscopic papillectomy (EP), surgical ampullectomy (SA), or pancreaticoduodenectomy (PD) is essential.

Binding Pancreaticojejunostomy: Is It Safe?

Niger J Surg 2020 Jan-Jun;26(1):48-52. Epub 2020 Feb 10.

Department of Surgery, Government Medical College and Hospital, Chandigarh, India.

Background: Postoperative pancreatic fistula (POPF) or leak from pancreaticojejunostomy (PJ) is one of the most common complications after pancreaticoduodenectomy (PD), with an incidence of 5%-30%. Various techniques have been advocated to bring down the incidence of POPF, but there is still none that can be called the "gold standard". Peng's binding PJ (BPJ) was proposed as a good method of performing PJ with low fistula rates; we present our results with BPJ. Read More

Department of Pathology, Woodland Hospital, Dhankheti, East Khasi Hills, Shillong, Meghalaya 793003, India.

Tumors involving the ampulla could be arising primarily in the ampulla or extending from the adjacent. When a neoplasm is centered primarily in the ampulla with or without periampullary mucosal involvement, it is considered a primary ampullary carcinoma. These tumors generally have a better prognosis than duodenal and pancreaticobiliary neoplasms secondarily involving the ampulla. Read More

Pancreatic Intraepithelial Neoplasia (PanIN) as a Morphologic Marker of Pancreatobiliary Type of Ampullary Carcinoma.

Pathol Oncol Res 2019 Oct 22. Epub 2019 Oct 22.

Arkadi M Rywlin Department of Pathology and Laboratory Medicine, Mount Sinai Medical Center, 4300 Alton road, Suite 2400, Miami Beach, FL, 33140, USA.

The classification of ampullary adenocarcinoma into intestinal and pancreatobiliary sub-types has been found to be important in predicting prognosis and determining therapeutic strategy. Due to considerable inter-observer variability in sub-typing based solely on morphology, higher frequency of poorly differentiated cancers and low incidence of the disease, the histomorphologic classification of ampullary adenocarcinoma remains one of the grey zones in surgical pathology. Pan-IN is a well recognized precursor to pancreatic adenocarcinoma. Read More

Oncol Rev 2019 Jul 10;13(2):440. Epub 2019 Sep 10.

Hematology-Oncology, University of Alabama at Birmingham Hospital, Birmingham, AL, USA.

Ampullary Carcinoma arises from a histologically heterogeneous region where three different epithelia converge. Even though Ampullary Carcinoma has a superior prognosis compared to pancreatic and biliary ductal neoplasms, at least half of the patients turn up at an advanced stage that limits the treatment prospects. In addition to surgery for early-stage disease, several studies have shown that chemoradiotherapy confers additional benefits in the management of Ampullary Carcinoma. Read More

Pancreatobiliary-type intraductal papillary mucinous neoplasm of the pancreas may have 2 subtypes with distinct clinicopathologic and genetic features.

Hum Pathol 2019 09 6;91:26-35. Epub 2019 Jun 6.

Department of Diagnostic Pathology, Kobe University Graduate School of Medicine, Kobe 650-0017, Japan; Institute of Liver Studies, King's College Hospital & King's College London, London SE5 9RS, United Kingdom. Electronic address:

We recently experienced cases of pancreatobiliary-type intraductal papillary mucinous neoplasms (PB-IPMNs) with imaging features resembling pancreatic ductal adenocarcinomas (PDACs), and histologic appearance of purely pancreatobiliary morphology and highly distorted papillary growth, which led to the present study aiming to systematically investigate PB-IPMNs in comparison with PDACs. Surgical cases of PB-IPMNs (n = 31) and PDACs (n = 24) were examined. PB-IPMNs were classified into monotypic tumors (n = 12; 39%) consisting of entirely high-grade pancreatobiliary-type neoplastic cells and polytypic cases (n = 19; 61%) associated with components of low-grade dysplasia and/or other histologic types (eg, gastric, intestinal, or oncocytic types).
