Review
This review examines the appropriate timing of intervention in acute pancreatitis. In gallstone pancreatitis, it is now clear that cholecystectomy during the primary admission carries no greater risk of complications than delayed cholecystectomy and enables earlier recovery to normal activity. This course of action pre-empts a second, possibly fatal attack of acute pancreatitis. Cholecystectomy should be done after the acute phase has settled, before discharge from hospital. Patients with gallstones should now be offered endoscopic sphincterotomy within 48 hours of admission. This approach is safe, and reduces the risk of complications. When complications develop, early necrosectomy is only indicated if conservative measures fail. Delayed (> 10 days) necrosectomy is appropriate if there is evidence of sepsis, or clinical failure to improve. Pancreatic pseudocysts can often be managed expectantly; a high proportion will resolve spontaneously. After a delay of 12 weeks, persistent cysts require evaluation by endoscopic pancreatography, which gives crucial information in the choice between percutaneous or surgical drainage of the pseudocyst. A patient with pancreatitis is usually treated under the care of a surgeon, who has traditionally taken the decision on the timing of any intervention, and has performed such intervention at open operation. Recently, the development of alternative techniques has enabled the surgeon to call on the skills of his colleagues in endoscopy and interventional radiology. However, the availability of these alternatives to surgery should not affect the timing of intervention unless it can be clearly shown that such a change in timing combined with the minimally invasive technique can improve the outcome for the patient. Intervention may be required to deal with gallstones in the gallbladder or in the bile duct, to deal with, or ideally prevent, the deleterious systemic effects of pancreatic and peripancreatic necrosis, or to drain a peripancreatic abscess. Peripancreatic fluid collections and pancreatic pseudocysts may also require either internal or external drainage to relieve symptoms or prevent complications.

BACKGROUND
Currently, the preoperative diagnosis of a pancreatic cyst is based on clinical and imaging findings, frequently in conjunction with chemical analysis of cyst fluid and cytologic evaluation. The purpose of these diagnostic tests is to distinguish benign from malignant cysts of the pancreas. Accordingly, it is imperative to distinguish pancreatic pseudocysts from their mimics. In this study, the authors explored the cytomorphologic features of pseudocyst of the pancreas and evaluated the role of Alcian blue and mucicarmine stains in the cytologic evaluation of pancreatic cysts.
METHODS
Forty-two patients were identified who had an eventual diagnosis of pancreatic pseudocyst and had an endoscopic ultrasound-guided fine-needle aspirate available. Clinical and imaging findings and chemical analyses of cyst fluid were recorded. The cytologic preparations were evaluated for gastrointestinal contamination, inflammatory cells, mucin, and pigmented material. The cytomorphologic features of 110 neoplastic mucinous cysts (intraductal papillary-mucinous neoplasms/mucinous cystic neoplasms of the pancreas) were evaluated and compared with the pseudocysts.
RESULTS
The majority of patients (95%) had a prior episode of pancreatitis. On imaging, the pseudocysts were unilocular (92%). In 69% of cases, the endosonographic diagnosis was that of a pseudocyst. The mean carcinoembryonic antigen level was 41 ng/mL. In contrast, the cytopathologist rendered a definitive diagnosis of pseudocyst in only 10% of cases. The majority of smears (75%) revealed neutrophils and/or histiocytes. Atypical epithelial clusters were identified in 3 cases, 1 of which was diagnosed as suspicious for carcinoma. Yellow pigmented material, which was identified in 13 pseudocysts (31%), was not observed in neoplastic mucinous cysts. Alcian blue- and mucicarmine-positive material was identified in 64% and 40% of pseudocysts, respectively, and in 57% and 38% of neoplastic mucinous cysts, respectively.
CONCLUSIONS
The diagnosis of a pseudocyst depended primarily on clinical and imaging findings and on chemical analysis of cyst fluid. The cytologic features frequently were nonspecific. The presence of yellow pigmented material served as a surrogate marker of a pseudocyst. Special stains for mucin did not distinguish pseudocysts from neoplastic mucinous cysts.

INTRODUCTION AND IMPORTANCE
A pancreatic pseudocyst is a known complication of acute and chronic pancreatitis. A pseudocyst rupture into the abdomen causes peritonitis, which can be fatal if surgical treatment is delayed. Here in we report the case of a 46-year-old woman presenting with a pancreatic pseudocyst doubly complicated with infection and rupture causing sepsis shock.
CASE PRESENTATION
A 46 year-old-woman, with a history of chronic pancreatitis four years prior complicated with a pancreatic pseudocyst of 3 cm, presented to our emergency department with clinical signs of generalized peritonitis. After a brief resuscitation, we performed a midline laparotomy. It showed purulent peritonitis due to a rupture of an infected pseudocyst of the pancreas. We performed an abundant peritoneal toilet with drainage. The patient was discharged after 25 days. In the one month follow-up, there were no unfavourable outcomes.
CLINICAL DISCUSSION
In presence of ruptured and infected pancreatic pseudocyst, surgical treatment should be performed as soon as possible after brief resuscitation. Laparotomy is the gold standard treatment. The main objective of surgical treatment is to perform abundant peritoneal toilet with large external drainage. In our case, the pancreatic pseudocyst didn't communicate with the Wirsung duct allowing us to withdraw the drainage. Otherwise, the drainage should be retained longer to treat the pancreatic leakage.
CONCLUSION
Rupture and infection of pancreatic pseudocysts is a rare situation. Diagnosis is assessed via computed tomography scan. Emergency laparotomy should be performed timely to make the peritoneal toilet and drain the pancreatic pseudocyst.

Review
Endoscopic drainage for pancreatic and peripancreatic fluid collections (PFCs) has been increasingly used as a minimally invasive alternative to surgical or percutaneous drainage. Recently, endoscopic ultrasound-guided transluminal drainage (EUS-TD) has become the standard of care and a safe procedure for nonsurgical PFC treatment. EUS-TD ensures a safe puncture, avoiding intervening blood vessels. Single or multiple plastic stents (combined with a nasocystic catheter) were used for the treatment of PFCs for EUS-TD. More recently, the use of covered self-expandable metallic stents (CSEMSs) has provided a safer and more efficient approach route for internal drainage. We focused our review on the best approach and stent to use in endoscopic drainage for PFCs. We reviewed studies of EUS-TD for PFCs based on the original Atlanta Classification, including case reports, case series, and previous review articles. Data on clinical outcomes and adverse events were collected retrospectively. A total of 93 patients underwent EUS-TD of pancreatic pseudocysts using CSEMSs. The treatment success and adverse event rates were 94.6% and 21.1%, respectively. The majority of complications were of mild severity and resolved with conservative therapy. A total of 56 patients underwent EUS-TD using CSEMSs for pancreatic abscesses or infected walled-off necroses. The treatment success and adverse event rates were 87.8% and 9.5%, respectively. EUS-TD can be performed safely and efficiently for PFC treatment. Larger diameter CSEMSs without additional fistula tract dilation for the passage of a standard scope are needed to access and drain for PFCs with solid debris.

INTRODUCTION
According to the literature exocrine pancreatic insufficiency is relatively common among patients with diabetes mellitus (DM). Pseudocysts are the most common cystic lesions and may be formed in the setting of acute or chronic pancreatitis. However, whether DM is involved or not in pancreatic cyst formation is still not well established.
AIM
To investigate the frequency and risk factors of cystic lesions in diabetic patients.
MATERIAL AND METHODS
One hundred and sixty-one patients with DM, with no previous history of pancreatic diseases, were prospectively included in the study. Endosonography followed by fine needle aspiration biopsy was then performed.
RESULTS
Finally, 33 of 161 patients (20.5%) were recognized with cystic lesions of the pancreas. Among them 5 patients were classified as cystic neoplasms, and 28 as pseudocysts. In the group of patients with pseudocysts, cystic lesions were significantly more prevalent in individuals with DM lasting less than 3 years. Prevalence of cystic lesions was significantly higher in metformin users in comparison to other diabetic patients ( < 0.05). Cystic lesions were more frequent in patients above 50 years of age ( < 0.05).
CONCLUSIONS
The prevalence of cystic lesions in the diabetic population is higher than in the general population. DM seems to play a major role in the process of cyst development, especially in patients without previous history of pancreatitis. Higher prevalence of cystic lesions in early diabetes seems to be the first stage of pancreatic injury. The exact role of diabetes duration and type of treatment should be established.

Review
Pancreatic fluid collections (PFCs) develop as a result of damage to the major or peripheral pancreatic ducts, complication due to acute or chronic pancreatitis, trauma or iatrogenic causes. PFCs include pancreatic pseudocysts (PPs) and walled-off necrosis (WON). PFCs usually resolve spontaneously and are asymptomatic, but if they persist, increase in dimension or became symptomatics, therapeutic intervention is required. Available therapeutic interventions include surgical, percutaneous, and endoscopic drainage. The endoscopic approach is nowadays considered the first line-treatment of PFCs due to various advantages when compared with surgical or percutaneous drainage: decreased morbidity, length of hospital stay, and reduced costs. In the last few years, the endoscopic ultrasound (EUS)-guided transmural drainage, initially with plastic stents, gained popularity. More recently, fully covered self-expanding lumen-apposing metal stents (LAMS) have been demonstrated to be both, safe and effective with high clinical and technical success, reducing the risk of perforation, peritoneal leakage, migration and facilitating the drainage of necrotic contents. In the last few years, several studies evaluating the safety and efficacy of LAMS and their differences with plastic stents have been performed, but literature on the removal timing of this device and associated complications is still limited. The aim of this review is to analyze studies reporting information about the retrieval timing of LAMS and the related adverse events.

Traumatic lung pseudocyst is an uncommon lung injury due to closed chest trauma. Four cases are reported; all were male and one was a child. Three cases showed spontaneous resolution of the pseudocyst and in one case, where resolution was slow, lobectomy was carried out at the patient's insistence. Diagnosis poses no serious problems as there is inevitably a history of substantial chest trauma. The chest radiograph shows a characteristic cavitatory lesion. The pseudocysts may be multiple. Tomography may be helpful in diagnosis and computed tomography can be particularly useful in the demonstration of paramediastinal traumatic pseudocysts.

Review
A wide variety of renal neoplasms can have cystic areas. These can occur for different reasons: some tumors have an intrinsic cystic architecture, while others exhibit pseudocystic degeneration of necrotic foci or they have cystically dilated renal tubules constrained by stromal neoplastic cells. Clear cell renal cell carcinoma (CCRCC), either solid or cystic, is the most frequent type of renal cancer. While pseudocysts are found in high-grade aggressive CCRCC, cystic growth is associated with low-grade indolent cases. The latter also form through a cyst-dependent molecular pathway, and they are more frequent in patients suffering from VHL disease. The differential diagnosis of multilocular cystic renal neoplasm of low malignant potential and clear cell papillary renal cell tumor can be especially hard and requires a focused macroscopical and microscopical pathological analysis. As every class of renal tumor includes cystic forms, knowledge of the criteria required for a differential diagnosis is mandatory.

Review
Chronic pancreatitis is associated with varied morphological complications, including intraductal stones, main pancreatic ductal strictures, distal biliary strictures and pseudocysts. Endoscopic therapy provides a less invasive alternative to surgery. In addition, extracorporeal shockwave lithotripsy improves the success rate of endoscopic clearance of intraductal stones. However, recent data from randomised trials have shown better long-term outcomes with surgical drainage for obstructive pancreatic ductal disease. In patients with distal biliary strictures, stent insertion leads to good immediate drainage, but after stent removal, recurrent narrowing is common. Endoscopic drainage of pancreatic pseudocysts has excellent outcome and should be accompanied by pancreatic ductal stenting when a ductal communication is evident. In those who remain symptomatic, endoscopic ultrasonography-guided coeliac plexus block may provide effective but short-term pain relief. In this review, we present the current evidence for the role of endotherapy in the management of patients with chronic pancreatitis.

Pancreatic cysts are usually asymptomatic over 70% of the time. They can be benign or malignant. Enhanced imaging modalities and increased usage of routine imaging have increased the identification of pancreatic cysts. If symptomatic, abdominal pain or back pain, unexplained weight loss, jaundice, steatorrhea or palpable mass are usually the presenting complaints. Pancreatic cysts are typically assessed by cross-sectional computed tomography (CT) and magnetic resonance imaging (MRI). In this article, we present a case of a 33-year-old female with a recurrent large pancreatic pseudocyst, initially measured 15.8 cm x 14 cm x 14 cm, who was subsequently admitted to our unit and managed successfully. After undergoing diagnostic laparoscopy, exploratory laparotomy, and pancreatic cystogastrostomy, the pseudocyst shrunk to 8 cm x 6 cm over 13 weeks. It is rare to come across a pseudocyst of such large dimensions. Despite its large size, the patient presented with vague abdominal pain as the only chief complaint. The unusual presentation of symptoms and the enormous size of the pseudocyst make this a unique case. Managing giant pancreatic pseudocysts can be complex, as seen in this scenario by the multiple approaches attempted to treat the pseudocyst.
