Concept: Pancreatic pseudocyst
Chronic pancreatitis (CP) is a common gastrointestinal illness, which affects the quality of life with substantial morbidity and mortality. The management includes medical, endoscopic and surgical approaches with the need for interaction between various specialties, calling for a concerted multidisciplinary approach. However, at the time of this publication, guidelines to establish care of these patients are lacking. This review provides the reader with a comprehensive overview of the studies summarizing the various treatment options available, including medical, surgical and endoscopic options. In addition, technological advances such as endoscopic retrograde cholangiopancreatogrophy, endoscopic shock wave lithotripsy and endoscopic ultrasound can now be offered with reasonable success for pancreatic decompression, stricture dilatation with stent placement, stone fragmentation, pseudocyst drainage, and other endoscopic interventions such as celiac plexus block for pain relief. We emphasize the endoscopic options in this review, and attempt to extract the most up to date information from the current literature. The treatment of CP and its complications are discussed extensively. Complications such as biliary strictures. pancreatic pseudocysts, and chronic pain are common issues that arise as long-term complications of CP. These often require endoscopic or surgical management and possibly a combination of approaches, however choosing amongst the various therapeutic and palliative modalities while weighing the risks and benefits, makes the management of CP challenging. Treatment goals should be not just to control symptoms but also to prevent disease progression. Our aim in this paper is to advocate and emphasize an evidence based approach for the management of CP and associated long term complications.

Pancreatic pseudocysts are frequent complications following acute and chronic pancreatitis as well as abdominal trauma. They originate from enzymatic and/or necrotizing processes within the organ involving the surrounding tissues through inflammatory processes following pancreatic ductal lesion(s). Pseudocysts require definitive treatment if they become symptomatic, progressive, larger than 5 cm after a period of more than 6 weeks and/or have complications. Cystic neoplasms must be excluded before treatment. Endoscopic interventions are commonly accepted first line approaches. Should these fail or not be feasible surgical procedures have been well established and show comparable results. In summary, pancreatic pseudocysts require a reliable diagnostic approach with a multidisciplinary professional management involving gastroenterologists and surgeons.
BACKGROUND: Endosonography (EUS)-guided transmural pseudocyst drainage is a multistep procedure currently performed with different “off-the-shelf” accessories developed for other applications. Multiple device exchanges over-the-wire is time consuming and risks loss of wire access. This report describes the technical feasibility and outcomes for EUS-guided drainage of pancreatic fluid collections using a novel exchange-free device developed for translumenal therapy. METHODS: Between April and November 2010, 14 patients (9 men; mean age, 49.9 years) with pancreatic fluid collection (mean size, 102 mm) underwent 16 EUS-guided drainage procedures using the exchange-free access device at a single tertiary care center. The trocar of the exchange-free device was used to gain pseudocyst access. The dual-balloon catheter then was advanced over the trocar, followed by inflation of the (first) anchor balloon. Cyst contents were sampled, and contrast was injected to define the pseudocyst anatomy. The first guidewire was inserted into the cyst cavity. The cystenterostomy tract was dilated to 10 mm with the (second) dilation balloon, followed by a second guidewire insertion. The exchange-free access device was removed, leaving the two guidewires in place for two double-pigtail stents. RESULTS: The procedure was technically successful for all the patients. No acute procedure-related complications occurred. Late complications included a symptomatic leak in a patient who underwent drainage of a pancreatic uncinate pseudocyst from the second duodenum, a self-limited transfusion-dependent bleed after transbulbar drainage, and symptomatic pseudocyst infection. CONCLUSION: Pseudocyst access, cystenterostomy tract dilation, and placement of two guidewires for dual stent drainage are technically feasible using an exchange-free access device. The device has the potential to standardize, simplify, and streamline EUS-guided pseudocyst drainage with a single instrument. Comparative studies with alternative tools and methods for pseudocyst drainage are warranted.
BACKGROUND: The presence of debris within a pseudocyst may impair success of endoscopic drainage. OBJECTIVE: To compare the clinical outcomes and adverse-event rates of EUS-guided pseudocyst drainage with and without a nasocystic drain for the management of pancreatic pseudocysts with viscous solid debris-laden fluid. DESIGN: Retrospective study. SETTING: Single, tertiary-care referral center. PATIENTS: Consecutive patients with pancreatic pseudocysts managed by EUS-guided drainage: those with solid debris who underwent drainage via nasocystic drains alongside stents (n = 63) and those with solid debris who underwent drainage via transmural stents only (n = 24). INTERVENTION: Drainage via nasocystic drains alongside stents or drainage via transmural stents only. MAIN OUTCOME MEASUREMENTS: The primary outcomes were short-term success and long-term success of the procedures. The secondary outcomes were procedure-related adverse events and reintervention. RESULTS: The patients with viscous solid debris-laden fluid whose pseudocysts were drained by both stents and nasocystic tubes had a 3 times greater short-term success rate compared with those who had drainage by stents alone (P = .03). On 12-month follow-up, complete resolution of pseudocysts with debris drained via stents alone was less (58%) compared with those with debris who underwent drainage via nasocystic drains alongside stents (79%; P = .059). The rate of stent occlusion was higher in cysts with debris drained by stents alone (33%) compared with those drained via nasocystic drains alongside stents (13%; P = .03). LIMITATIONS: Retrospective design; limited sample size. CONCLUSION: In patients with pseudocysts with viscous debris-laden fluid, EUS-guided drainage by using a combination of a nasocystic drain and transmural stents improves clinical outcomes and lowers the stent occlusion rate compared with those who underwent drainage via stents alone.
To investigate outcomes of pancreatic extracorporeal shock wave lithotripsy (P-ESWL) for the removal of large pancreatic stones coexisting with pancreatic pseudocysts (PPCs) in chronic pancreatitis (CP).
Pancreatic duct disruption is a challenging condition leading to pancreatic juice leakage and consequently to pancreatic fluid collections. The manifestations of pancreatic main duct leak include pseudocysts, walled-off necrosis, pancreatic fistulas, ascites, pleural and pericardial effusions. Pseudocyst formation is the most frequent outcome of a pancreatic duct leak.
Endosonographically guided transgastric drainage is the first-line interventional therapy of walled-off necrosis and symptomatic pancreatic pseudocysts in necrotizing pancreatitis. Plastic stents or lumen apposing metal stents are commonly used. A possible complication of endoscopic therapy is stent migration.

Open surgical intervention for treatment of simple pancreatic pseuodocyst (PP) has a high success rate and has been the historical gold standard. Open surgical intervention, however, confers significant morbidity and mortality, which has spurred the development of less invasive techniques. Laparoscopic approaches are feasible with the potential for lower complication rates and length of stay. The endoscopic approach has the appeal of potentially shorter hospitalization length of stays and does not require general anesthesia. Complicated PPs or those that arise in the setting of chronic pancreatitis warrant additional workup and special consideration.

Pancreatic pseudocyst is the most common pancreatic cystic disease in clinical practice.In the surgical treatment of pancreatic pseudocysts, most surgeons preferred laparoscopic surgery in recent years.The options and the timing of laparoscopic surgery for pancreatic pseudocysts in different situations are explored in the paper.Pancreatic pseudocysts during the observation period, the imaging examination to detect whether the cyst has disappeared or increased, such as cysts found to be enlarged or still can not dissipate after 6 months, the largest diameter greater than 6 cm, and clinical symptoms, surgical drainage should be considered treatment.Surgery based on the location of the cyst and surgical experience of surgical options.Pancreatic cyst often choose laparoscopic cyst-gastric anastomosis, far from the stomach cyst should choose laparoscopic cyst-jejunal anastomosis.Laparoscopic surgery for the treatment of pancreatic pseudocyst has a unique advantage, short operation time, less bleeding, less trauma, less postoperative complications, rapid recovery, is a safe and effective treatment options.
The treatment of pancreatic pseudocysts has evolved during the past two decades. Endoscopic treatment (ET) has gradually become used as a first-line management even though it showed no significant superiority to surgical internal drainages (SIDs) in a recent randomized trial. The objective of the present work was to analyze the effect of ET failure on the results of SID in the global management of pancreatic pseudocysts.
