Hepatobiliopancreatic surgery is challenging becouse of the complexity of resections and reconstructions and variability of vascular anatomy. The arterial vascularization of the liver is susteined by the common hepatic artery (CHA) that originates from the celiac trunk (CT). The CHA bifurcates into the gastroduodenal artery (GDA) and proper hepatic artery (PHA) 0.5-1 cm medial to the common bile duct (CBD), and the PHA bifurcates into a right and a left branch at hepatic hilum. The most frequent variants are the right hepatic artery (RHA) from the superior mesenteric artery (SMA), the left hepatic artery (LHA) from the left gastric artery (LGA) or a combination of these two variants...

Context: The mechanisms by which beta cell mass is reduced in patients with type 2 diabetes (T2DM) remain unclear. It has been postulated that ectopic fat deposits in the pancreas induce beta cell apoptosis, leading to the development of diabetes. Objective: The aim of this study was to clarify the effects of intra-pancreatic fat on beta and alpha cell mass in humans with and without diabetes. Design, Subjects and Methods: Using our tissue database, pancreas sections of 72 Japanese non-diabetic (NDM) autopsy cases and 50 diabetic (DM) and 49 age- and BMI-matched NDM patients who underwent pancreatic surgery were analyzed...

Gastric duplication cyst is a very rare gastrointestinal tract malformation that accounts for 2%-4% of alimentary tract duplications. It is a diagnostic dilemma for doctors because its clinical and radiological manifest is usually nonspecific. At the present stage, it can only rely on surgery. We should pay attention to ectopic pancreas resection and ligation of pancreatic duct during operation. There was one case of gastric duplication cyst with ectopic pancreas in adults from the Second Affiliated Hospital of Nanchang University...

Comorbidities have considerable effects on survival outcomes. The primary objective of this retrospective study was to examine the association between age-adjusted Charlson comorbidity index (ACCI) score and postoperative in-hospital mortality in patients with digestive system cancer who have undergone surgical resection of their cancers. Using electronic hospitalization summary reports, we identified 315,464 patients who had undergone surgery for digestive system cancer in top-rank (Grade 3A) hospitals in China between 2013 and 2015...

Insulinoma is the most common functioning islet cell tumor of the pancreas, with an annual incidence of 4 cases/1 million individuals. It is treated by surgical methods. Open surgery was once considered the standard approach for the treatment of insulinoma. However, the procedure is traumatic and requires a large incision, which does not satisfy the growing expectations of minimally invasive management of small-sized tumors. Insulinomas are usually benign solitary tumors and mostly occur sporadically, which makes them suitable candidates for laparoscopic management...

REVIEW
Zeljka Jutric, Laleh G Melstrom
In the United States, cancer of the pancreas accounts for nearly 40,000 deaths annually and is the fourth leading cause of cancer-related mortality. The vast majority of patients present with metastatic or unresectable disease. Only 20% of patients are candidates for surgery, and therefore curable. The 5-year survival rate for patients with pancreatic adenocarcinoma is only 6%, with surgical resection being essential for long-term survival. Recent research has identified a precise subset of patients with borderline resectable pancreatic cancer for whom resection yielding durable survival is possible...

BACKGROUND: Even though most patients who undergo resection of pancreatic adenocarcinoma have T3 disease with extra-pancreatic tumor extension, T3 disease is not currently classified by tumor size. The aim of this study was to modify the current TNM classification of pancreatic adenocarcinoma to reflect the influence of tumor size. METHODS: A total of 847 consecutive pancreatectomy patients were recruited from multiple centers. Optimum tumor size cutoff values were calculated by receiver operating characteristics analysis for tumors limited to the pancreas (T1/2) and for T3 tumors...

We hereby present the case of a 58-year-old male who underwent a total gastrectomy for gastric neoplasm. During the surgery, a tumor mass in the jejunum was identified, considered as metastasis, and resected. The histopathological examination of the jejunal lesion showed ectopic pancreas. In this area, two pathological distinct lesions were identified, one histologically compatible with pancreatic intraepithelial neoplasia (PanIN) type 2 lesion and the other with morphologic criteria for endocrine microadenoma...

BACKGROUND AND AIMS: Neuroendocrine tumors (NETs) are a heterogeneous group of neoplasms with unclear etiology that may show functioning or non-functioning features. Primary tumor localization often requires integrated imaging. The European Neuroendocrine Tumors Society (ENETS) guidelines proposed wireless-capsule endoscopy (WCE) as a possible diagnostic tool for NETs, if intestinal origin is suspected. However, its impact on therapeutic management is debated. We aimed to evaluate the yield of WCE in detecting intestinal primary tumors in patients showing liver NET metastases when first-line investigations are inconclusive...

INTRODUCTION: We present a 51 year old, African American, female who presented with persistent hypoxemia. She had been taking dapsone for many years for prophylaxis against Pneumocystic Jiroveci with no symptoms but eventually developed methemoglobinemia only after a splenectomy. From our literature review there are no documented cases that have demonstrated this relationship between dapsone, splenic function and methemoglobin and we hope to share our perplexing case and shed light on the interaction...

BACKGROUND: Pancreatic texture is one of the key predictors of postoperative pancreatic fistula (POPF) after pancreatoduodenectomy (PD). Currently, the "gold standard" for assessment of pancreatic texture is surgeon's subjective evaluation through manual palpation. AIM: To evaluate a new "durometer" that is able to assess quantitatively the pancreatic stiffness by measuring its elastic module (i.e., the resistance offered by the pancreatic stump when elastically deformed expressed in mPa)...

PURPOSE: Independent Academic Medical Centers (IAMCs) comprise one-third of U.S. general surgery training programs. It is unclear whether IAMCs offer qualitatively or quantitatively different operative experiences than the national cohort. We analyzed a large representative sample of IAMCs to compare operative volume and variety, with a focus on low-volume procedures. METHODS: Accreditation Council for Graduate Medical Education Program Case Reports from 27 IAMCs were collected and analyzed for 3 academic years (2012-2015)...

BACKGROUND: Despite randomized trials addressing adjuvant therapy (AT) for pancreas cancer, the ideal time to initiate therapy remains undefined. Retrospective analyses of the ESPAC-3 trial demonstrated that time to initiation of AT did not impact overall survival (OS). Given the absence of confirmatory data outside of a clinical trial, we sought to determine if AT timing in routine clinical practice is associated with OS differences. METHODS: Perioperative data of pancreatectomies for ductal adenocarcinoma from five institutions (2005-2015) were assessed...

We present an the case of an eight-year-old Portuguese boy with no history of traveling, admitted with non-specific abdominal pain. An analytic study revealed high levels of lipase and amylase. Ultrasound, abdominal computerized tomography (CT), and an abdominal magnetic resonance imaging (MRI), were performed. The imaging findings are suggestive of a pancreatic tumor which is an extremely rare entity in children. A biopsy was performed by opened surgery and identified a Burkitt lymphoma.

BACKGROUND: Surgical site infections (SSIs) are a common source of postoperative morbidity and a marker of surgical quality. The ability to predict the incidence of SSIs is limited and most models have poor predictive value. We sought to identify risk factors associated with SSIs and develop a prediction model for SSIs after major abdominal surgery. METHODS: A total of 1744 patients undergoing pancreatic, hepatobiliary, and colorectal resections between January 1, 2010 and August 31, 2013 at Johns Hopkins Hospital were identified...

Vladimir Neychev, Electron Kebebew
Our understanding of the biology, genetics, and natural history of neuroendocrine tumors (NETs) of the gastrointestinal tract and pancreas has improved considerably in the last several decades and the spectrum of available therapeutic options is rapidly expanding. The management of patients with metastatic low or intermediate grade NETs has been revolutionized by the development of new treatment strategies such as molecular targeting therapies with everolimus and sunitinib, somatostatin analogs, tryptophan hydroxylase inhibitors, and peptide receptor radionuclide therapy that can be used alone or as a multimodal approach with or without surgery...

BACKGROUND: Leiomyosarcoma of the head and neck is a rare cancer with high local aggressiveness. Radical surgery and adjuvant treatment offer the best chance for cure, nonetheless 5-years recurrence rate remains high. Despite international guidelines are available for soft tissue sarcomas, no recommendations are specifically endorsed for leiomyosarcoma of the head and neck, due to the rarity of its presentation and consequently scarcity of data on long-term outcome. CASE PRESENTATION: A 50-year old woman, operated 10 years before for leiomyosarcoma of the nasal pit and with negative 5-years follow-up, was admitted to our ward for impairment of the hepatic function...
