Pancreatic fluid collections are a frequent complication of acute pancreatitis. The revised Atlanta criterion classifies chronic fluid collections into pseudocysts and walled-off pancreatic necrosis (WON). Symptomatic PFCs require drainage options that include surgical, percutaneous, or endoscopic approaches. With the advent of newer and more advanced endoscopic tools and expertise, minimally invasive endoscopic drainage has now become the preferred approach. An endoscopic ultrasonography (EUS)-guided approach for pancreatic fluid collection drainage is now the preferred endoscopic approach...

Pancreatic ascites and effusion is a challenging complication to manage, hence our aim was to evaluate the efficacy of pancreatic endotherapy in pancreatic ascites and pleural effusion. Endotherapy included endoscopic retrograde cholangiopancreatography (ERCP) with a pancreatogram and pancreatic stent placement across the leak in patients with pancreatic ascites/effusion. A total of 53 patients were included after successful cannulation. The male:female ratio was 7.8:1. The pancreatogram revealed a leak from the pancreatic duct in 20/53 (37...

Children requiring reimplantation of a branch pulmonary artery (PA) are at risk for postoperative stenosis and impaired growth of the reimplanted PA. Outcomes and risk factors for reintervention and impaired growth are incompletely described. We reviewed data on patients who underwent reimplantation of a branch PA between 1/1/99 and 5/1/15 at a single center. The primary outcome was reintervention to treat postoperative stenosis. The secondary outcome was "catch-up" growth (faster diameter growth of the affected PA compared with the unaffected PA from the preoperative to follow-up measurements...

The last decade has seen dramatic shift in paradigm in the management of pancreatic fluid collections with the rise of endoscopic therapy over radiologic or surgical management. Endosonographic drainage is now considered the gold standard therapy for pancreatic pseudocyst. Infected pancreatic necroses are being offered endoscopic necrosectomy that has been facilitated by the arrival on the market of large diameter lumen-apposing metal stent. Severe pancreatitis or failure to thrive should receive enteral nutrition while pancreatic ductal disruption or strictures are best treated by pancreatic stenting...

Several risk factors for pancreatic fistula had been widely reported, but there was no research focusing on the exocrine output of remnant gland.During the study period of January 2015 to September 2016, 82 patients accepted pancreaticoduodenectomy (PD, end-to-end dunking pancreaticojejunostomy with internal stent tube). All the data were collected, including preoperative medical status, operative course, final pathology, gland texture, pancreatic duct diameter, size of the stent, length of pancreatic juice in the stent tube, width of the pancreatic stump, diameter of the jejunum and the status of postoperative pancreatic fistula (POPF)...

An 85-year-old woman underwent endoscopic retrograde cholangiopancreatography (ERCP) for obstructive jaundice. Selective bile duct cannulation was unsuccessful because of periampullary diverticula (PAD). A pancreatic spontaneous dislodgement stent (PSDS) (5F diameter, 3 cm, straight type) was inserted to prevent post-ERCP pancreatitis. Three days after ERCP, she complained of abdominal pain, and computed tomography revealed retroperitoneal perforation because of PSDS migration to the PAD. If the papillary orifice is observed at the diverticular rim or in the diverticula, a pigtailed PSDS on the duodenal side or flanged stent on the pancreatic ductal side should be inserted in order to prevent this rare adverse event...

Background -Infants with ductal-dependent pulmonary blood flow may undergo palliation with either a patent ductus arteriosus (PDA) stent or modified Blalock-Taussig (BT) shunt. A balanced multi-center comparison of these two approaches is lacking. Methods -Infants with ductal-dependent pulmonary blood flow, palliated with either PDA stent or BT shunt from 1/08 to 11/15, were reviewed from the four member centers of the Congenital Catheterization Research Collaborative. Outcomes were compared using propensity score adjustment to account for baseline differences between groups...

In isolated unilateral ductal origin of a pulmonary artery (DOPA), intervention to establish reperfusion of the affected lung without direct re-anastomosis may lead to pulmonary hypertension (PH) in the contralateral lung. Multicenter retrospective review of patients with unilateral DOPA, who underwent palliation with a ductal stent (DS) or Blalock-Taussig (BT) shunt with subsequent development of PH in the contralateral lung, was conducted. Ten patients (4 females; median weight 3.2 kg, range 2.1-5.2) who underwent DS or BT shunt and developed contralateral PH were identified...

In neonates, the management of ductus dependent pulmonary circulation is challenging. There have been three palliative therapies for this lesion: the modified Blalock-Taussig shunt, ductal stenting and prostaglandin E infusions, for maintaining the ductal patency before definite operations. Debates remain with regard to the indications and disadvantages of three palliative therapies. The aim of this article is to give a brief review of these three palliative therapies.

Aims The aim of this study was to describe atrial septal defect morphology in hypoplastic left heart syndrome, to report the incidence of restrictiveness and its relationship with defect morphology, to correlate restriction with midterm outcome, and to describe our interventional approach to restrictive defect. Methods and results From 2011 to 2015, 31 neonates with hypoplastic left heart syndrome underwent hybrid procedure with pulmonary artery banding and ductal stenting at our Institution. Restrictive physiology of the atrial septal defect was based on Doppler gradient >6 mmHg through the defect and on clinical signs of pulmonary hypertension...

Combined hepatocellular-cholangiocarcinoma (HCC-CC) with bile duct invasion (BDI) is rare. In unresectable cases, biliary stent placement and photodynamic therapy (PDT) are used for resolving obstructive jaundice. However, stent occlusion remains problematic, and PDT is expensive and time-consuming. Intraductal radiofrequency ablation (RFA) is an emerging procedure for palliation in these patients. It has potential benefits including less expense, lower rates of severe complication, longer maintenance of ductal patency, and easier technique compared with PDT or stenting alone...

Significant and balanced PA growth following arterial duct (AD) stenting has already been consistently reported in literature. However, to date, no data are available about the role of this approach as palliation of congenital heart disease with a duct-dependent discontinuous pulmonary artery (dPA). The aim of this study was to evaluate the fate of a dPA of ductal origin following trans-catheter AD stabilization. Angiographic PA evaluation was performed in seven patients submitted to neonatal AD stenting as palliative recruitment of dPA...

A common complication of radioiodine (I(131)) treatment of thyroid cancer is parotitis. Here we describe our clinical experience in treating delayed I(131)-induced parotitis using sialoendoscopy together with an internal stent and postoperative massage. In this retrospective cohort study we reviewed 32 patients who were treated in that way under general anaesthesia between July 2010 and March 2015. Their age, sex, and the time to development of the parotitis were collected from the hospital's database. All patients were evaluated using a visual analogue scale (VAS), sialography, and computed tomography preoperatively...

BACKGROUND: Infants with severe tetralogy of Fallot may undergo (1) early primary surgical repair (EARLY) or (2) early transcatheter palliation (CATH) before delayed surgical repair. We compared these strategies with (3) elective single-stage tetralogy of Fallot repair (IDEAL). METHODS: From 2000 to 2012, 453 children underwent tetralogy of Fallot repair (excluding systemic-pulmonary shunts), including 383 in the IDEAL (75%), 42 in the EARLY (9%), and 28 in the CATH (6%) groups...

Tetralogy of Fallot with absent pulmonary valve syndrome (TOF/APV) is a rare congenital malformation. Although pulmonary artery (PA) anomalies have been observed in TOF, its association with disconnected PA is extremely rare. We report successful stenting of the disconnected left PA in a 3-year-old boy with TOF/APV followed by surgical reimplantation. The significance of this transcatheter intervention for guidance during surgery and the importance of visualizing a ductal stump on angiography as an indicator of disconnected PA are discussed...

AIM: To identify factors predicting outcome of endoscopic therapy in bile duct strictures (BDS) post living donor liver transplantation (LDLT). METHODS: Patients referred with BDS post LDLT, were retrospectively studied. Patient demographics, symptoms (Pruritus, Jaundice, cholangitis), intra-op variables (cold ischemia time, blood transfusions, number of ducts used, etc.), peri-op complications [hepatic artery thrombosis (HAT), bile leak, infections], stricture morphology (length, donor and recipient duct diameters) and relevant laboratory data both pre- and post-endotherapy were studied...

OBJECTIVES: We aimed to compare the procedural and mid-term performance of a specifically designed self-expanding stent with balloon-expandable stents in patients undergoing hybrid palliation for hypoplastic left heart syndrome and its variants. BACKGROUND: The lack of specifically designed stents has led to off-label use of coronary, biliary, or peripheral stents in the neonatal ductus arteriosus. Recently, a self-expanding stent, specifically designed for use in hypoplastic left heart syndrome, has become available...
