Lumbar Artery Pseudoaneurysms Presenting as a Novel Complication of Severe, Necrotizing Pancreatitis.

Splanchnic artery pseudoaneurysms are a known complication of necrotizing pancreatitis. Lumbar artery pseudoaneurysms are rare and usually associated with trauma, renal biopsy, or spinal procedures. We present a rare case of lumbar artery pseudoaneurysms as a complication of necrotizing pancreatitis.

EUS-guided coil injection therapy in the management of gastric varices: the first U.S. multicenter experience (with video).

Background And Aims: Despite the significant morbidity associated with gastric variceal bleeding, there is a paucity of high-quality data regarding optimal management. EUS-guided coil injection therapy (EUS-COIL) has recently emerged as a promising endoscopic modality for the treatment of gastric varices (GV), particularly compared with traditional direct endoscopic glue injection. Although there are data on the feasibility and safety of EUS-COIL in the management of GV, these have been limited to select centers with particular expertise.

Multidisciplinary Management of Complicated Pancreatitis: What Every Interventional Radiologist Should Know.

Management of acute pancreatitis is challenging in the presence of local complications that include pancreatic and peripancreatic collections and vascular complications. This review, targeted for interventional radiologists, describes minimally invasive endoscopic, image-guided percutaneous, and surgical procedures for management of complicated pancreatitis and provides insight into the procedures' algorithmic application. Local complications are optimally managed in a multidisciplinary team setting that includes advanced endoscopists; pancreatic surgeons; diagnostic and interventional radiologists; and specialists in infectious disease, nutrition, and critical care medicine.

Characterization of long-term prognosis in acute pancreatitis: An explorative analysis.

Background/objectives: Severity classification systems of acute pancreatitis (AP) assess inpatient morbidity and mortality without predicting outpatient course of AP. To provide appropriate outpatient care, determinants of long-term prognosis must also be identified. The aim of this study was to define clinical groups that carry long-term prognostic significance in AP.

Endoscopic Drainage of >50% of Liver in Malignant Hilar Biliary Obstruction Using Metallic or Fenestrated Plastic Stents.

Objectives: Endoscopic drainage of complex hilar tumors has generally resulted in poor outcomes. Drainage of >50% of liver volume has been proposed as optimal, but not evaluated using long multifenestrated plastic stents (MFPS) or self-expanding metal stents (SEMS). We evaluated outcomes of endoscopic drainage of malignant hilar strictures using optimal strategy and stents, and determined factors associated with stent patency, survival, and complications.

Visceral Adiposity Predicts Severity of Acute Pancreatitis.

Objectives: The aim of this study was to determine the association of visceral adiposity with severe outcomes in acute pancreatitis (AP).

Methods: This retrospective study included consecutive patients with AP admitted to a tertiary care hospital between January 2010 and January 2015 who underwent a computed tomography scan. The visceral adipose tissue (VAT) volume was estimated using the method of Linder and colleagues.

Pancreatitis of ectopic pancreatic tissue: a rare cause of gastric outlet obstruction.

Inflammation in ectopic pancreatic tissue can clinically present with pain or obstructive symptoms, depending on the location of the ectopic tissue. We present a rare case of gastric outlet obstruction secondary to pancreatitis of ectopic pancreatic tissue in the pylorus.

Endoscopic transluminal drainage and necrosectomy by using a novel, through-the-scope, fully covered, large-bore esophageal metal stent: preliminary experience in 10 patients.

Background: Interventions for necrotizing pancreatitis have undergone a recent paradigm shift toward minimally invasive techniques, including endoscopic transluminal necrosectomy (ETN). The optimal stent for endoscopic transmural drainage remains unsettled.

Objective: To evaluate a novel large-bore, fully covered metal through-the-scope (TTS) esophageal stent for cystenterostomy in large walled-off necrosis (WON).

A comparison of surgical outcomes and quality of life surveys in right lobe vs. left lateral segment liver donors.

Concern remains regarding the possibly higher risk to living liver donors of the right lobe (RL), as compared with the left lateral segment (LLS). We studied outcomes and responses to quality of life (QOL) surveys in the two groups. From 1997 to 2004, we performed 49 living donor liver transplants (LDLTs): 33 RL and 16 LLS.

Living donor and split-liver transplants in hepatitis C recipients: does liver regeneration increase the risk for recurrence?

Concern exists that partial liver transplants (either a living donor [LD] or deceased donor [DD] in hepatitis C virus (HCV)-positive recipients may be associated with an increased risk for recurrence. From 1999 to 2003, at our institution, 51 HCV-positive recipients underwent liver transplants: 32 whole-liver (WL) transplants, 12 LD transplants and 7 DD split transplants. Donor characteristics differed in that WL donors were older, and LD livers had lower ischemic times.

Regionwide sharing for status 1 liver patients--beneficial impact on waiting time and pre- and posttransplant survival.

On August 21, 1999, Region 7 of the United Network for Organ Sharing (UNOS) adopted a policy of regionwide sharing of cadaver livers for UNOS Status 1 recipients. We examined what impact this policy had at our center on their waiting times, waiting list mortality, and outcomes. From January 1, 1995, through December 31, 2002, our center listed 39 patients for an emergent (Status 1) transplant, according to the current criteria for Status 1 listing: patients (adult and pediatric) with fulminant hepatic failure (FHF), hepatic artery thrombosis, or primary nonfunction early after a liver transplant, or critically ill pediatric patients with chronic liver disease.

Liver regeneration after adult living donor and deceased donor split-liver transplants.

As the number of living donor (LD) and deceased donor (DD) split-liver transplants (SLTs) have increased over the last 5 years, so too has the interest in liver regeneration after such partial-liver transplants. We looked at liver regeneration, as measured by computed tomography (CT) volumetrics, to see if there were significant differences among LDs, right-lobe LD recipients, and SLT recipients. We measured liver volume at 3 months postoperatively by using CT, and we compared the result to the patient's ideal liver volume (ILV), which was calculated using a standard equation.
