Literature review and robotic management of a rare case of primary retroperitoneal mucinous cystadenoma.

Primary retroperitoneal mucinous cystic tumors (PRMCT) are divided into 3 groups: benign, borderline malignancy, and malignant. We report a rare case of benign retroperitoneal mucinous cystadenoma of a 59-year-old Caucasian female who presented to our clinic with moderate intermittent left upper quadrant abdominal pain for several months, accompanied by early satiety, and unintentional weight loss of 10 pounds. An abdominal contrast-enhanced computed tomography (CT) scan indicated the presence of a 6.

Liver Transplant Costs and Activity After United Network for Organ Sharing Allocation Policy Changes.

Importance: A new liver allocation policy was implemented by United Network for Organ Sharing (UNOS) in February 2020 with the stated intent of improving access to liver transplant (LT). There are growing concerns nationally regarding the implications this new system may have on LT costs, as well as access to a chance for LT, which have not been captured at a multicenter level.

Objective: To characterize LT volume and cost changes across the US and within specific center groups and demographics after the policy implementation.

Intraductal papillary mucinous neoplasm of the intrahepatic bile duct: a review of literature and a rare case report.

Background: Intraductal papillary neoplasm of the bile duct is a rare variant of bile duct tumors, which is characterized by papillary or villous growth inside the bile duct. Having papillary and mucinous features such as those found in pancreatic intraductal papillary mucinous neoplasm (IPMN) is extremely rare. We report a rare case of intraductal papillary mucinous neoplasm of the intrahepatic bile duct.

A rare synchrony of adenocarcinoma of the ampulla with an ileal gastrointestinal stromal tumor: A case report.

Background: This is a unique case of a patient who was found to have two extremely rare primary malignancies synchronously, , an ampullary adenocarcinoma arising from a high-grade dysplastic tubulovillous adenoma of the ampulla of Vater (TVAoA) with a high-grade ileal gastrointestinal stromal tumor (GIST). Based on a literature review and to the best of our knowledge, this is the first report of this synchronicity. Primary ampullary tumors are extremely rare, with an incidence of four cases million population, which is approximately 0.

External Beam Radiation Therapy for Primary Liver Cancers: An ASTRO Clinical Practice Guideline.

Purpose: This guideline provides evidence-based recommendations for the indications and technique-dose of external beam radiation therapy (EBRT) in hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (IHC).

Methods: The American Society for Radiation Oncology convened a task force to address 5 key questions focused on the indications, techniques, and outcomes of EBRT in HCC and IHC. This guideline is intended to cover the definitive, consolidative, salvage, preoperative (including bridge to transplant), and adjuvant settings as well as palliative EBRT for symptomatic primary lesions.

Addressing the worldwide hepatocellular carcinoma: epidemiology, prevention and management.

Hepatocellular carcinoma (HCC) is the sixth most common cancer in the world with rising incidence. Globally, there has been substantial variation in prevalence of risk factors for HCC over years, like control of viral hepatitis in developing countries but growing epidemic of fatty liver disease in developed world. Changing epidemiology of HCC is related to trends in these risk factors.

Considerations for resuming global surgery outreach programs during and after the coronavirus disease 2019 (COVID-19) pandemic.

Background: The coronavirus disease 2019 pandemic has disrupted the delivery of safe surgical care worldwide. One specific aspect of global surgical care that has been severely limited is the ability for physicians and trainees to participate in global surgical outreach programs in low- and middle-income countries.

Methods: A narrative review of the literature regarding global surgical outreach programs during the coronavirus disease 2019 pandemic was performed.

Cholestatic liver diseases: An era of emerging therapies.

Recently the field of cholestasis has expanded enormously reflecting an improved understanding of the molecular mechanisms underlying bile secretion and its perturbation in chronic cholestatic disease. Novel anti-cholestatic therapeutic options have been developed for patients not favorably responding to ursodeoxycholic acid (UDCA), the current standard treatment for cholestatic liver disease. Important novel treatment targets now also include nuclear receptors involved in bile acid (BA) homoeostasis like farnesoid X receptor and G protein-coupled receptors .

Incidental liver metastasis in pancreatic adenocarcinoma.

Exocrine cancer of pancreas is the fourth leading cause of death in the USA among both men and women. Contrast enhanced multidetector-row computer tomography (MDCT) is the current modality of choice for the detection of distant metastasis in pancreatic cancer as a part of pre-operative workup, which helps decide on resectability. Authors present a first ever reported case of an incidental liver metastasis found on intra-operative wedge hepatic biopsy during Whipple's procedure for pancreatic cancer.

Influence of facility type on survival outcomes after pancreatectomy for pancreatic adenocarcinoma.

Introduction: Although a volume-outcome relationship has been well established for pancreatectomy, little is known about differences in mortality by facility type. The objective of this study is to evaluate the impact of facility type on short-term and long-term survival outcomes for patients with pancreatic adenocarcinoma who underwent pancreatectomy and identify determinants of overall survival (OS).

Methods: A cohort of 33,382 patients with Stage I-III pancreatic adenocarcinoma diagnosed between 1998 and 2011 were evaluated from the National Cancer Data Base.

Kidney outcomes in patients with liver cirrhosis and chronic kidney disease receiving an orthotopic liver transplant alone.

Kidney transplant in patients with liver cirrhosis and nondialysis chronic kidney disease (CKD) is controversial. We report 14 liver cirrhotic patients who had persistently low MDRD-6 estimated glomerular filtration rate (e-GFR) <40 mL/min/1.73 m for ≥3 months and underwent either liver transplant alone (LTA; n=9) or simultaneous liver-kidney transplant (SLKT; n=5).

Impact of Plasma Glucose Level at the Time of Fluorodeoxyglucose Administration on the Accuracy of FDG-PET/CT in the Diagnosis of Pancreatic Lesions.

Background: High fasting plasma glucose (FPG) levels before fluorodeoxyglucose (FDG) administration for positron emission tomography/computed tomography (PET/CT) might affect the accuracy of 18-fluoro-deoxy-glucose-positron emission tomography-computed tomography (FDG-PET/CT) in diagnosis of pancreatic lesions. Current guidelines require FPG levels of < 200 mg/dL before FDG administration; however, the literature on the effect of FPG levels of < 200 mg/dL on the accuracy of FDG-PET/CT is scarce.

Objectives: The aim of this study was to evaluate the effect of FPG levels of < 200 mg/dL on the accuracy of FDG-PET/CT in diagnosis of pancreatic lesions.

Torsed hepaticoileostomy-an unusual complication of Bile Duct injury repair.

We present a 42-year-old male with strictured bilioenteric anastomosis after bile duct injury repair. The patient improved after percutaneous biliary drainage and balloon dilation of the stricture. Persistent bile reflux around the catheter insertion site prompted a cholangiogram that suggested an error in the enteric limb.

Portal-endocrine and gastric-exocrine drainage technique of pancreas transplantation provides an easy access for evaluation of pancreatic allograft dysfunction: six-year experience at a single center.

Background: The aim of this study is to report our six-year experience with portal-endocrine and gastric-exocrine drainage technique of pancreatic transplantation, which was first developed and implemented at our center in 2007.

Methods: In this study, the outcomes of all patients at our center who had pancreas transplantation with portal-endocrine and gastric-exocrine drainage technique were evaluated.

Results: From October 2007 to November 2013, 38 patients had pancreas transplantation with this technique - 31 simultaneous kidney pancreas and seven pancreas alone.

Aberrant left main bile duct draining directly into the cystic duct or gallbladder: an unreported anatomical variation and cause of bile duct injury during laparoscopic cholecystectomy.

Despite recent advances, iatrogenic bile duct injury remains one of the most common complications of laparoscopic cholecystectomy. Aberrant biliary tract anatomy is one of the major risk factors for iatrogenic bile duct injury. In this case report, for the first time, we report a case of aberrant left main bile duct draining directly into the cystic duct or gallbladder that presented with bile duct injury after laparoscopic cholecystectomy.

Curative resection of pancreatic adenocarcinoma with major venous resection/repair is safe procedure but will not improve survival.

Objective: To evaluate the safety and survival benefit of combined curative resection (CR) of the pancreas and major venous resection in the management of borderline resectable pancreatic adenocarcinoma.

Methods: In this IRB approved retrospective cohort study, patients who had pancreatic surgery (n=274) between 1998-2012 were reviewed. One hundred and seventy-five patients had malignant causes, of which 119 underwent CR.

Mucinous cystic neoplasm of pancreas in a male patient: a case report and review of the literature.

Mucinous cystic neoplasms (MCNs) are among the most common primary cystic neoplasms of pancreas. These lesions usually occur in body and tail of the pancreas and are characterized by the presence of ovarian type stroma in the pathological evaluation. Mucinous cystic neoplasms have significant malignant potential; therefore, their diagnosis and resection is of utmost importance.
