Robotic Cyst Gastrostomy and Roux-en-Y Cyst Jejunostomy for a Bilobed Walled-Off Pancreatic Necroma.

Background: Walled-off pancreatic necrosis (WON) represents delayed sequelae of necrotizing pancreatitis, generally developing in 5-15% of cases 4 weeks after the initial attack (Boškoski and Costamagna Ann Gastroenterol 27(2):93-94, 2014). They are characterized by a well-circumscribed, encapsulated collection of necrotic parenchyma with variable degree of gland liquefaction (Boškoski and Costamagna Ann Gastroenterol 27(2):93-94, 2014, Khreiss et al. J Gastrointest Surg 19(8):1441-1448, 2015).

A prospective study of the use of central venous catheters in patients newly diagnosed with acute myeloid leukemia treated with induction chemotherapy.

Purpose: Central venous catheters (CVCs) are widely used in acute myeloid leukemia (AML) patients. Complications associated with CVCs are frequently encountered and contribute to morbidity and mortality. Prospective studies investigating and comparing complications of different types of CVCs in AML patients and their effects on the quality of life are limited.

Robotic Pancreaticoduodenectomy for a Technically Challenging Pancreatic Head Cancer.

Background: Robotic pancreaticoduodenectomy (RPD) is performed for resectable periampullary lesions with comparable outcomes to the open approach.1 Surgical therapy for borderline-resectable (BR) pancreatic tumors is technically challenging and poses a significant risk of bleeding and positive margins.2 As experience with RPD grows at high-volume centers, case selection can be carefully expanded to include complex vascular resections.

Laparoscopic-assisted ERCP following RYGB: a 12-year assessment of outcomes and learning curve at a high-volume pancreatobiliary center.

Introduction: Treatment of pancreaticobiliary pathology following Roux-en-Y gastric bypass (RYGB) poses significant technical challenges. Laparoscopic-assisted endoscopic retrograde cholangiopancreatography (LA-ERCP) can overcome those anatomical hurdles, allowing access to the papilla. Our aims were to analyze our 12-year institutional outcomes and determine the learning curve for LA-ERCP.

National Trends in Robotic Pancreas Surgery.

Background: Robotic pancreatic surgery is expanding throughout centers across the country. We investigated national trends in the use and outcomes for robotic-assisted pancreaticoduodenectomy (RPD) and distal pancreatectomy (RDP) for primary pancreatic tumors.

Methods: The National Cancer Database was queried for RPD and RDP performed during three time periods: 2010-2012, 2013-2014, and 2015-2016.

Can post-hoc video review of robotic pancreaticoduodenectomy predict portal/superior mesenteric vein margin status in pancreatic adenocarcinoma?

Background: Achieving margin negative resection is a significant determinant of outcome in pancreatic adenocarcinoma (PDA). However, because of the fibrotic nature of PDA, it can be difficult to discriminate fibrosis from active disease intra-operatively. We sought to determine if post-hoc video review of robotic pancreatico-duodenectomy (RPD) could predict the portal/superior mesenteric vein (PV/SMV) margin status on final pathology.

Safety and feasibility of the robotic platform in the management of surgical sequelae of chronic pancreatitis.

Background/aim: The application of minimally invasive surgery to chronic pancreatitis (CP) procedures is uncommon. Our objective was to report the safety and feasibility of the robotic approach in the treatment of surgical sequelae of CP, and provide insights into the technique, tricks, and pitfalls associated with the application of robotics to this challenging disease entity.

Methods: A retrospective review of a prospectively maintained database of patients undergoing robotic-assisted resections and/or drainage procedures for CP at the University of Pittsburgh between May 2009 and January 2017 was performed.

Development of Minimally Invasive Pancreatic Surgery: an Evidence-Based Systematic Review of Laparoscopic Versus Robotic Approaches.

Introduction: Laparoscopic and robotic surgery of the pancreas has only recently emerged as viable treatment options for benign and malignant disease. This review seeks to evaluate the current body of evidence on these approaches to pancreaticoduodenectomy and distal pancreatectomy.

Methods: A systematic review of large published series was performed utilizing the PubMed search engine.

Hepatocellular Carcinoma: Past and Future of Molecular Target Therapy.

Hepatocellular carcinoma (HCC) is one of the most common causes of cancer related mortality worldwide. The incidence of HCC has been increasing annually. Viral infection, alcohol usage, and other causes of cirrhosis have been identified as major risk factors for HCC development.

Primary central nervous system post-transplant lymphoproliferative disorders following allogeneic hematopoietic stem cell transplantation.

Post-transplant lymphoproliferative disorder (PTLD) is a serious complication after allogeneic hematopoietic stem cell transplantation (HSCT). Extra nodal involvement is common in PTLD, but isolated involvement of the central nervous system (CNS) is extremely rare. Given the rarity of primary CNS-PTLD there is no consensus on optimal treatment.

N-gram analysis of 970 microbial organisms reveals presence of biological language models.

Background: It has been suggested previously that genome and proteome sequences show characteristics typical of natural-language texts such as "signature-style" word usage indicative of authors or topics, and that the algorithms originally developed for natural language processing may therefore be applied to genome sequences to draw biologically relevant conclusions. Following this approach of 'biological language modeling', statistical n-gram analysis has been applied for comparative analysis of whole proteome sequences of 44 organisms. It has been shown that a few particular amino acid n-grams are found in abundance in one organism but occurring very rarely in other organisms, thereby serving as genome signatures.

Randomized, multinational, phase III study of docetaxel plus platinum combinations versus vinorelbine plus cisplatin for advanced non-small-cell lung cancer: the TAX 326 study group.

Purpose: To investigate whether docetaxel plus platinum regimens improve survival and affect quality of life (QoL) in advanced non-small-cell lung cancer (NSCLC) compared with vinorelbine plus cisplatin as first-line chemotherapy.

Patients And Methods: Patients (n = 1,218) with stage IIIB to IV NSCLC were randomly assigned to receive docetaxel 75 mg/m2 and cisplatin 75 mg/m2 every 3 weeks (DC); docetaxel 75 mg/m2 and carboplatin area under the curve of 6 mg/mL * min every 3 weeks (DCb); or vinorelbine 25 mg/m2/wk and cisplatin 100 mg/m2 every 4 weeks (VC).

Results: Patients treated with DC had a median survival of 11.
