BACKGROUND
/Objectives: A cystic lesion is common in the pancreas. Focal pancreatic parenchymal atrophy (FPPA) has been reported as a sign of high-grade pancreatic intraepithelial neoplasia/carcinoma in situ (HGP/CIS). Some cystic lesions accompany FPPA. However, the relationship between a cystic lesion, FPPA, and the histopathological background of the pancreatic duct is unknown.
METHODS
We retrospectively evaluated the data of 98 patients with a cystic lesion who underwent serial pancreatic juice aspiration cytologic examination (SPACE) because of accompanying FPPA, increased size of the cystic lesion, and pancreatic duct stricture at the base.
RESULTS
The clinical diagnosis of a cystic lesion was intraductal papillary mucinous neoplasia (IPMN) and cysts in 72 (73.5%) and 26 (26.5%) patients, respectively. Ninety of the 98 patients (91.8%) had FPPA. Positive results (adenocarcinoma and suspicion) on SPACE were observed in 56 of all cases (57.1%), 48 of IPMN (66.7%), 8 of cysts (30.8%), and 54 of FPPA (59.3%), and were significantly associated with IPMN (p = 0.002) and the large FPPA (>269.79 mmp = 0.0001); moreover, these disorders are considerably related (p = 0.0003). Fifty patients (51.0%) with positive results on SPACE underwent surgery, with the histopathological diagnosis of epithelial malignancy in 42 patients (42.9%, 42/50, 84%). Many cystic lesions clinically diagnosed as IPMN were dilated branches covered by pancreatic intraepithelial neoplasia.
CONCLUSIONS
Positive results on SPACE were significantly associated with the clinical diagnosis of IPMN and the large FPPA. Moreover, these disorders are significantly related. Surgery owing to positive results could lead to the histopathological diagnosis of HGP/CIS.

Chronic pancreatitis and pancreatic lithiasis, isolated or associated, are infrequent diseases in western countries. They are linked to alcohol abuse, cigarette smoking, repeated episodes of acute pancreatitis and hereditary genetic factors. They are characterised by persistent or recurrent epigastric pain, digestive insufficiency, steatorrhoea, weight loss and secondary diabetes. They are easily diagnosed with CT and MRI ultrasound, but are difficult to treat. Medical therapy is symptomatic for diabetes and digestive failure. Invasive treatment is indicated only for pain that cannot be treated otherwise. For lithiasic forms, the therapeutic goal of removing stones can be achieved with shockwave and endoscopy, obtaining fragmentation and extraction of the stones. When this does not happen and these aids have proved ineffective, surgery must be used either as a partial or total resection of the afflicted pancreas, or as a derivation in the intestine of the pancreatic duct dilated and obstructed by Wirsung-jejunal anastomosis. These invasive treatments are effective in 80% of cases, but burdened with complications in 10% and relapses in 5%. KEY WORDS: Chronic Pancreatitis, Chronic Pain, Pancreatic Lithiasis.

Meta-Analysis
BACKGROUND
Necrotizing pancreatitis may lead to loss of integrity of the pancreatic duct, resulting in leakage of pancreatic fluid. Pancreatic duct disruption or disconnection is associated with a prolonged disease course and particular complications. Since a standard treatment for this condition is currently lacking, we performed a systematic review of the literature to compare outcomes of various treatment strategies.
METHODS
A systematic review was performed according to the PRISMA guidelines in the PubMed, EMBASE and Cochrane databases. Included were articles considering the treatment of patients with disrupted or disconnected pancreatic duct resulting from acute necrotizing pancreatitis.
RESULTS
Overall, 21 observational cohort studies were included comprising a total of 583 relevant patients. The most frequently used treatment strategies included endoscopic transpapillary drainage, endoscopic transluminal drainage, surgical drainage or resection, or combined procedures. Pooled analysis showed success rates of 81% (95%-CI: 60-92%) for transpapillary and 92% (95%-CI: 77-98%) for transluminal drainage, 80% (95%-CI: 67-89%) for distal pancreatectomy and 84% (95%-CI: 73-91%) for cyst-jejunostomy. Success rates did not differ between surgical procedures (cyst-jejunostomy and distal pancreatectomy (risk ratio = 1.06, p = .26)) but distal pancreatectomy was associated with a higher incidence of endocrine pancreatic insufficiency (risk ratio = 3.06, p = .01). The success rate of conservative treatment is unknown.
DISCUSSION
Different treatment strategies for pancreatic duct disruption and duct disconnection after necrotizing pancreatitis show high success rates but various sources of bias in the available studies are likely. High-quality prospective, studies, including unselected patients, are needed to establish the most effective treatment in specific subgroups of patients, including timing of treatment and long-term follow-up.

Observational Study
PURPOSE
To study the safety, efficacy, and long-term outcomes of percutaneous pancreatic duct drainage (PPDD) for treating pancreatic duct (PD) obstruction.
MATERIALS AND METHODS
This prospective observational cohort study included 73 patients with PD obstruction between December 2010 and June 2020. Patients underwent PPDD under ultrasound and fluoroscopy guidance, computed tomography (CT) and fluoroscopy guidance, or CT guidance only. They were categorized into 2 groups: nonmalignant (26 patients with PD obstruction due to acute and chronic pancreatitis or postoperative stricture) and malignant (47 patients with pancreatic head and ampullary tumors).
RESULTS
The overall technical success rate was 98.6% (72/73). No major complications were encountered; however, severe weakness, lack of appetite, and tachycardia were observed in 4.1% (3/73) of patients, managed with intravenous resuscitation. Multivariate analysis demonstrated that diagnosis type (pancreatic head tumor: P = .049; odds ratio = 1.95 [1.11-2.25], and chronic pancreatitis: P = .048; odds ratio = 6.25 [1.74-22.22]) was associated with mortality. The median survival time was 16.3 months. Moreover, 15.1% (11/73) of the patients were alive 4 years after the PPDD procedure, and the mean overall survival time of nonmalignant and malignant patients was 35.1 and 21.4 months, respectively.
CONCLUSIONS
Image-guided PPDD appears to be feasible and safe and provides a valuable therapeutic option for managing patients with PD obstruction.

Three-dimensional surgical simulation, already in use for hepatic surgery, can be used in pancreatic surgery. However, some problems still need to be overcome to achieve more precise pancreatic surgical simulation. The present study evaluates the performance of SYNAPSE VINCENT® (version 6.6, Fujifilm Medical Co., Ltd., Tokyo, Japan) in the semiautomated surgical simulation of the pancreatic parenchyma, pancreatic ducts, and peripancreatic vessels using an artificial intelligence (AI) engine designed with deep learning algorithms. One-hundred pancreatic cancer patients and a control group of 100 nonpancreatic cancer patients were enrolled. The evaluation methods for visualizing the extraction were compared using the Dice coefficient (DC). In the pancreatic cancer patients, tumor size, position, and stagewise correlations with the pancreatic parenchymal DC were analyzed. The relationship between the pancreatic duct diameter and the DC, and between the manually and AI-measured diameters of the pancreatic duct were analyzed. In the pancreatic cancer/control groups, the pancreatic parenchymal DC and pancreatic duct extraction were 0.83/0.86 and 0.84/0.77. The DC of the arteries (portal veins/veins) and associated sensitivity and specificity were 0.89/0.88 (0.89/0.88), 0.85/0.83 (0.85/0.82), and 0.82/0.81 (0.84/0.81), respectively. No correlations were observed between pancreatic parenchymal DC and tumor size, position, or stage. No correlation was observed between the pancreatic duct diameter and the DC. A positive correlation (r = 0.61, p<0.001) was observed between the manually and AI-measured diameters of the pancreatic duct. Extraction of the pancreatic parenchyma, pancreatic duct, and surrounding vessels with the SYNAPSE VINCENT® AI engine assumed to be useful as surgical simulation.

Review
Trauma affects all sociodemographic profiles and is a major cause of morbidity and mortality particularly in patients less than forty years of age. A variety of endoscopic tools and techniques initially used for iatrogenic etiologies (post-operative bile or pancreatic duct leaks, intra-procedural perforation) have been adopted for use in the gastrointestinal trauma victim. The purpose of this review is to highlight a variety of gastrointestinal traumatic complications where endoscopy can serve a complement and/or definitive management strategy.

Review
Pancreaticobiliary (PB) endotherapy continues to progress in the era of therapeutic endosonography. Endoscopic retrograde cholangiopancreatography (ERCP) remains the primary method for PB access in native and altered anatomy. In altered anatomy, PB access can be obtained via enteroscopy-assisted ERCP (e-ERCP) or laparoscopy-assisted ERCP; however, both approaches have significant limitations. Endoscopic ultrasound-guided biliary and pancreatic duct drainage (EUS-BPD) are increasingly becoming the preferred alternative when ERCP fails, with advantages over percutaneous drainage. EUS-BPD continues to evolve with better feasibility, safety and efficacy as dedicated procedural equipment continues to improve. In this article, we discuss the role of endoscopic ultrasound (EUS) when ERCP fails and their indications, technique, and outcomes.

INTRODUCTION
Necrotizing pancreatitis may result in a disrupted or disconnected pancreatic duct (DPD) with the potential for long-lasting negative impact on a patient's clinical outcome. There is a lack of detailed data on the full clinical spectrum of DPD, which is critical for the development of better diagnostic and treatment strategies.
METHODS
We performed a long-term post hoc analysis of a prospectively collected nationwide cohort of 896 patients with necrotizing pancreatitis (2005-2015). The median follow-up after hospital admission was 75 months (P25-P75: 41-151). Clinical outcomes of patients with and without DPD were compared using regression analyses, adjusted for potential confounders. Predictive features for DPD were explored.
RESULTS
DPD was confirmed in 243 (27%) of the 896 patients and resulted in worse clinical outcomes during both the patient's initial admission and follow-up. During hospital admission, DPD was associated with an increased rate of new-onset intensive care unit admission (adjusted odds ratio [aOR] 2.52; 95% confidence interval [CI] 1.62-3.93), new-onset organ failure (aOR 2.26; 95% CI 1.45-3.55), infected necrosis (aOR 4.63; 95% CI 2.87-7.64), and pancreatic interventions (aOR 7.55; 95% CI 4.23-13.96). During long-term follow-up, DPD increased the risk of pancreatic intervention (aOR 9.71; 95% CI 5.37-18.30), recurrent pancreatitis (aOR 2.08; 95% CI 1.32-3.29), chronic pancreatitis (aOR 2.73; 95% CI 1.47-5.15), and endocrine pancreatic insufficiency (aOR 1.63; 95% CI 1.05-2.53). Central or subtotal pancreatic necrosis on computed tomography (OR 9.49; 95% CI 6.31-14.29) and a high level of serum C-reactive protein in the first 48 hours after admission (per 10-point increase, OR 1.02; 95% CI 1.00-1.03) were identified as independent predictors for developing DPD.
DISCUSSION
At least 1 of every 4 patients with necrotizing pancreatitis experience DPD, which is associated with detrimental, short-term and long-term interventions, and complications. Central and subtotal pancreatic necrosis and high levels of serum C-reactive protein in the first 48 hours are independent predictors for DPD.
