BACKGROUND: Pancreaticoduodenectomy (PD) is a complex procedure for management periampullary neoplasms The aim of our work is to report the surgical outcomes after PD in young adult (YA) (<35 years) and to compare it to a adult patients who underwent PD. METHODS: We retrospectively analyzed the data of all patients who underwent PD in the period from January 1993 to December 2016. The primary outcome was the rate of total postoperative complications. Secondary outcomes included postoperative pathology, exocrine and endocrine function and survival rate...

Gangliocytic paraganglioma (GP) is a rare tumor of uncertain origin most often located in the second portion of the duodenum. It is composed of three cellular components: Epithelioid endocrine cells, spindle-like/sustentacular cells, and ganglion-like cells. While this tumor most often behaves in a benign manner, cases with metastasis are reported. We describe the case of a 62-year-old male with a periampullary GP with metastases to two regional lymph nodes who was successfully treated with pancreaticoduodenectomy...

BACKGROUND: Unlike other neuroendocrine tumors of the gastrointestinal tract, management of duodenal and periampullary carcinoids remains controversial. We aimed to determine the metastatic potential and optimal choice of therapy for these neoplasms. METHODS: A retrospective review of all patients treated at the Johns Hopkins Hospital between 1996 and 2012 was conducted. Clinicopathologic factors associated with lymph nodal involvement and clinical outcomes were evaluated...

BACKGROUND: Predictors of recurrence following pancreaticoduodenectomy are well described for ductal periampullary cancers but lack reliability for non-ductal tumors. The purpose of this study is to analyze the disease-free survival (DFS) and to define the predictors of recurrence following resection for ampullary (AC), bile duct (BDC) and duodenal cancers (DC). MATERIALS AND METHODS: Clinico-pathological data of patients operated on between 2001 and 2011 were retrospectively reviewed...

Volume reduction of the pancreatic tissues following a pancreatectomy can lead to the deterioration of glucose homeostasis. This is defined as pancreatogenic diabetes mellitus (DM). The objective of this study was to investigate the occurrence of new-onset DM (NODM) and evaluate the risk factors, including the pancreas volume reduction rate in patients undergoing pancreaticoduodenectomy (PD).Sixty-six patients without preoperative DM underwent PD for periampullary tumors between August 2007 and December 2012 and were included in this analysis...

Periampullary duodenal diverticula are common and are usually asymptomatic. However, complications like biliary or pancreatic obstruction, duodenal obstruction, perforation, or hemorrhage can occur occasionally. Obstructive jaundice is usually due to biliary stones and periampullary tumors. Rarely, duodenal diverticula may present with obstructive jaundice in the absence of cholelithiasis or other detectable obstacle. This condition is called Lemmel's syndrome. There are only few case reports of this rare condition...

Hepatocyte growth factor (HGF) and MET are candidates of targeted therapies for cancer patients. Although MET and HGF are commonly expressed in biliary tract cancers, their expression and gene copy number status and their association with KRAS mutations have not been investigated in pancreatobiliary-type ampullary adenocarcinomas (A-ACs), one of the aggressive periampullary cancers. MET and HGF expressions and MET copy number status were examined by performing immunohistochemistry (IHC) and silver in situ hybridization (SISH) in 62 surgically resected, paraffin-embedded tumors, respectively...

Carcinoid tumors of the ampulla of Vater grow slowly and have an excellent prognosis after complete resection of local disease. Histopathological diagnosis is definitive, and the Whipple's procedure is performed as a standard at the present time, although more novel minimally-invasive techniques may be highly useful for selected patients. While tumor size is not a reliable marker of tumor aggression, it is nonetheless related to lymphatic invasion, hence an accurate diagnosis is important if the patient is to be offered the best option available for the treatment of their disease...

The aging of the population results in a rise of number of elderly patients (aged 80 years and older) with pancreatic or periampullary cancer, and more pancreatectomies could eventually be performed in such complex patients. However, early and long-term results after pancreatic resection in octogenarians are still controversial, and may trouble the surgeon when approaching this type of population. Evaluation of reported experiences shows that for almost all Authors, pancreatectomy can be performed safely in elderly population, although overall morbidity and mortality rates were 34...

Small bowel tumors are rare tumors. Duodenal tumors occur more commonly compared with other small intestinal tumors. To summarize the clinicopathological features of duodenal tumors, in the present study 44 cases of duodenal tumors were collected, and the comparative clinicopathological characteristics between tumors of the ampulla and non-ampulla, the choice of treatment, and differences in the prognosis, were analyzed. The pathological type identified was predominantly adenocarcinoma; periampullary duodenal tumors were almost classifiable as adenocarcinoma in terms of their type...

INTRODUCTION: Whipple's Pancreaticoduodenectomy has increasingly been used as an appropriate resectional procedure for tumors of the periampullary region which are pancreatic, periampullary, ampullary and biliary tumors. Our aim was to study the distribution and histopathologic features of these tumors and to examine local trends of periampullary neoplasms resected with a PD. METHODS: A descriptive study was conducted in the department of Pathology, Kathmandu Medical College Teaching Hospital from July 2013 to June 2016...

AIMS: Surgery is the only modality that offers cure for periampullary adenocarcinoma. However, surgery alone results in failure in 60% of patients. Studies have shown some benefits of chemotherapy in node positive and higher tumor stage patients. We sought to determine the role of adjuvant chemotherapy in early tumors with uninvolved nodes. METHODS: A retrospective analysis of a prospectively maintained database of patients resected of periampullary tumors from 2007 to 2014 was performed...

REVIEW
Stephanie M Kim, Jennifer R Eads
Pancreatic adenocarcinoma is a relatively uncommon malignancy associated with a high rate of cancer-related mortality despite best efforts to perform curative surgery. Adjuvant therapy in patients after surgical resection is associated with improved overall survival. Adjuvant treatment approaches may include either chemotherapy alone or a combination of chemotherapy and radiation therapy. Neoadjuvant approaches, also including either chemotherapy alone or a combination of chemotherapy and radiation therapy, are under investigation...

BACKGROUND: Long term patient-reported symptoms and quality of life (QOL) are important outcome metrics following cancer operations, but have been poorly described in patients who have previously undergone pancreatectomy. METHODS: We conducted a cross-sectional survey of recurrence-free survivors of pancreatic ductal adenocarcinoma, periampullary carcinomas, and pancreatic neuroendocrine tumors who had undergone prior pancreatectomy. QOL and symptom burden were measured using the Functional Assessment of Cancer Therapy-Hepatobiliary Questionnaire, and psychosocial distress was measured using the Hospital Anxiety and Depression Scale...

BACKGROUND & AIMS: Adenocarcinomas of the pancreatobiliary system are currently classified by their primary anatomical location. In particular, the pathological diagnosis of intrahepatic cholangiocarcinoma is still considered as a diagnosis of exclusion of metastatic adenocarcinoma. Periampullary cancers have been previously classified according to the histological type of differentiation (pancreatobiliary, intestinal), but overlapping morphological features hinder their differential diagnosis...

Microscopic residual tumor (R1) affects prognosis of resected pancreatic head cancer patients. Surgeon's ability, caseload and accuracy of pathological staging affect the rate of R1 resections. The goal of this study was to verify if a standardized histopathological workup of the specimen affects the rate of microscopic residual tumor after PD for cancer. Two groups of specimens were managed with (Group 1, Standardized Group, SG) or without (Group 2, Non Standardized Group, NSG) a standardized histopathological workup reported by the Royal College of Pathologists...

Importance: Patients with periampullary adenocarcinomas have widely variable survival. These cancers are traditionally categorized by their anatomic location of origin, namely, the duodenum, ampulla, distal common bile duct (CBD), or head of the pancreas. However, they can be alternatively subdivided histopathologically into intestinal or pancreaticobiliary (PB) types, which may more accurately estimate prognosis. Objectives: To identify factors associated with survival in patients with periampullary adenocarcinomas and to compare survival between those having intestinal-type or PB-type cancers originating from the duodenum, ampulla, or distal CBD with those having pancreatic ductal adenocarcinoma (PDAC)...

BACKGROUND: Stomach cancer is the second most commonly diagnosed cancer in Korea. Although the long-term survival outcome has improved, secondary primary tumors from periampullary regions are increasing inevitably and pancreaticoduodenectomy (PD) following gastrectomy is challenging. This study evaluates the surgical outcomes of PD following gastrectomy and suggests the optimum method for reconstruction. METHODS: Patients who underwent curative PD with a history of gastric resection between 2005 and 2015 were assessed retrospectively...
