BACKGROUND AND AIMS: EUS-guided transluminal drainage (EUS-TD) and sequential direct endoscopic necrosectomy (DEN) for pancreatic fluid collections (PFCs) using a dedicated biflanged metal stent (BFMS) has been reported as a useful alternative to using plastic stents or a conventional metal stent. However, current dedicated BFMSs have limitations. Recently, a new BFMS with solidly constructed biflanges and various stent lengths matched to the PFC condition has been developed. Herein, we prospectively evaluated this new BFMS for the treatment of PFCs...

A 53-year-old male visited his primary physician for epigastric and back pain. Abdominal-enhanced computed tomography (CT) revealed a simple cyst of the pancreatic tail attached to the stomach. A distal main pancreatic duct (MPD) was clearly dilated, but no pancreatic tumor was identified around the stenosis of MPD by CT scan and magnetic resonance cholangiopancreatography (MRCP). Endoscopic retrograde pancreatography (ERP) revealed stenosis and distal dilation of the MPD located between the body and tail of the pancreas...

OBJECTIVES: Pancreatic serous cystadenomas (SCAs) are benign tumors. Technological advances in imaging have led to increased recognition of asymptomatic pancreatic cysts, consequently increasing the demand for cytomorphologic evaluations of cyst fluid. STUDY DESIGN: A retrospective search through the pathology archives over an 11-year period was performed to identify SCAs from pancreatectomy specimens with a presurgical pancreatic EUS-guided fine-needle aspiration (FNA)...

Acute pancreatitis (AP) is a potentially serious disease whose incidence is on the increase. Pancreas divisum does not meet the required criteria to be considered an aetiological factor. Sphincter of Oddi dysfunction may be another cause of idiopathic AP. Less invasive methods cannot replace Sphincter of Oddi manometry in diagnosis. Almost half of patients with systemic inflammatory response syndrome develop organ failure, but the mechanisms involved are not completely understood. Obesity is a risk factor for severity in AP; the cause could be the presence of free unsaturated fatty acids, which have pro-inflammatory activity...

The management of disconnected pancreatic duct syndrome is complex and is increasingly approached using emerging endoscopic techniques. Here, we present a case of recurrent pancreatitis in an elderly woman complicated by pseudocyst formation and complete pancreatic duct disruption. Her condition was treated with a novel combination of transpapillary stenting and cystduodenostomy in which a pancreatic duct stent was placed into an opening in the pseudocyst wall via lumen-apposing metal stent. This allowed for effective drainage into the gastrointestinal tract and resolution of duct disruption...

BACKGROUND: Groove pancreatitis (GP) is a focal form of chronic pancreatitis affecting the paraduodenal groove area, for which consensus on diagnosis and management is lacking. GOALS: We performed a systematic review of the literature to determine patient characteristics and imaging features of GP and to evaluate clinical outcomes after treatment. RESULTS: Eight studies were included reporting on 335 GP patients with a median age of 47 years (range, 34 to 64 y), with 90% male, 87% smokers, and 87% alcohol consumption, and 47 months (range, 15 to 122 mo) of follow-up...

: Background and aims: Endoscopic ultrasound (EUS)-guided needle-based Confocal Laser Endomicroscopy (nCLE) characteristics of pancreatic cystic lesions (PCLs) have been identified in studies where the gold standard surgical histopathology was available in a minority of patients. There are diverging reports of interobserver agreement (IOA) and paucity of intraobserver reliability (IOR). Thus, we sought to validate current EUS-nCLE criteria of PCLs in a larger consecutive series of surgical patients...

OBJECTIVE: To study the effect of disconnected pancreatic duct syndrome (DPDS) on endoscopic management of pancreatic fluid collections (PFCs). BACKGROUND: Data on the impact of DPDS in patients undergoing endoscopic treatment of PFCs are limited. METHODS: Retrospective study of patients undergoing endoscopic drainage of PFCs from 2003 to 2015. If treatment response was suboptimal following initial endoscopic or endoscopic ultrasound-guided transmural drainage, hybrid interventions (endoscopic ultrasound-guided multigate/dual modality technique, endoscopic/percutaneous sinus tract necrosectomy) were performed...

Atraumatic splenic rupture is a rare complication of a pancreatic pseudocyst (PP), described in the setting of chronic pancreatitis. There is common understanding, within the literature, that an inflammatory process at the tail of the pancreas may disrupt the spleen and result in such splenic complications. The authors present a case report of a 29-year-old male with a PP, associated with chronic pancreatitis. The patient had a history of excessive alcohol intake and presented to the emergency department with a short history of abdominal pain and vomiting...

Portal hypertension induces collateral shunt formation between the portal and systemic circulation, decompressing the elevated portal pressure. Ectopic varices outside of the gastroesophageal region, such as jejunal varices, are rare conditions. This report describes the successful embolization of ruptured jejunal varices resulting from an extrahepatic portal obstruction. A 62-year-old man was admitted to our hospital with recurrent massive gastrointestinal bleeding. Fourteen months earlier, he had undergone a choledochojejunostomy and pancreatic cystojejunostomy for bile duct stenosis with an enlarged pancreatic pseudocyst due to severe chronic pancreatitis...

BACKGROUND AND AIMS: Prospective data have shown the benefit of rectal indomethacin (IND) for preventing post-ERCP pancreatitis (PEP). A recent pilot study demonstrated a lower incidence of PEP after an 8-hour lactated ringer's (LR) infusion. The aim of this study was to evaluate the efficacy of IND with or without bolus LR in patients at high-risk for PEP. METHODS: In this randomized, double-blinded, placebo-controlled trial we assigned patients to standard normal saline solution (NS)+placebo, NS+IND, LR+placebo or LR+IND...

A 9-year-old, spayed female toy poodle dog developed refractory anorexia after pancreatitis. Abdominal imaging showed a cystic structure compressing the stomach. Appetite improved after percutaneous drainage of the structure, but the structure refilled within 48 h. Percutaneous ethanol ablation of the structure was attempted. Afterwards, the patient developed fatal hypotensive shock.

Laparoscopic cystogastrostomy is a well-accepted minimally invasive modality to treat pancreatic pseudocysts. There has been one prior report of cystogastrostomy via single incision laparoscopic surgery (SILS) in which specialized instrumentation and access platforms were used.We report the challenges encountered in a low resource setting with the SILS approach to drainage using only standard laparoscopic instruments. To the best of our knowledge this is the second report of SILS cystogastrostomy and the first to be performed in a resource poor setting without specialized instruments or platforms...

Neutrophils form neutrophil extracellular traps (NETs) of decondensed DNA and histones that trap and immobilize particulate matter and microbial pathogens like bacteria. NET aggregates reportedly surround and isolate large objects like monosodium urate crystals, which cannot be sufficiently cleared from tissues. In the setting of acute necrotizing pancreatitis, massive tissue necrosis occurs, which is organized as pancreatic pseudocysts (1). In contrast to regular cysts, these pseudocysts are not surrounded by epithelial layers...
