Results: A total of 13 552 EGS patients received critical care; of these, 707 (5%) (mean [SD] age at hospital admission, 56.6 [14.2] years; 64% male; 79% white) had CLD and data to determine MELD score at ICU admission. The median MELD score was 14 (interquartile range, 10-20). Overall 90-day mortality was 30.1%. The adjusted odds ratio of 90-day mortality for each 10-point increase in MELD score was 1.63 (95% CI, 1.34-1.98). A decrease in MELD score of more than 3 in the 48 hours following ICU admission was associated with a 2.2-fold decrease in 90-day mortality (odds ratio = 0.46; 95% CI, 0.22-0.98).
Conclusions and relevance: In this study, MELD score was associated with 90-day mortality following EGS in patients with CLD. The MELD score can be used as a prognostic factor in this patient population and should be used in preoperative risk prediction models and when counseling EGS patients on the risks and benefits of operative intervention.
Results: Thirty patients experienced a BC: 13 BLs (3.3 %) and 17 BSs (4.3 %). A thin bile duct (<5 mm), measured during surgery, was the only predisposing factor for developing a BL or a BS. The management of the BLs consisted of surveillance in six patients (46 %), percutaneous drainage of bilioma in four patients (31 %), and reintervention in three patients (23 %). No patient with a BS had surgery as the frontline treatment: the initial management consisted of an endoscopic procedure, a percutaneous procedure, or medical treatment. Four patients (23.5 %) underwent surgical treatment after failure of nonsurgical procedures.
Conclusions: The only identified predictive factor of BC, either a BS or a BL, was a thin bile duct. Although the noninvasive technique was the treatment of choice initially, reintervention was required in almost 25 % of the cases.

The patient’s presentation, in combination with the results of their examination, should be used to stratify them to into three classes of sphincter of Oddi dysfunction. Specific diagnostic criteria for SOD include:
Transaminitis (greater 2 times the upper limit of normal on 2 or more occasions)
Common bile duct dilation (greater than 10 mm on US; greater than 12 mm on ERCP)
Utilizing these criteria, patients are classified as follows:
Type I SOD: all three Type II SOD: biliary pain and one of the other two criteria. Type III SOD: biliary pain only 
The results of this classification will impact the subsequent treatment plan.
Results: There were no differences between drain and no-drain cohorts in demographics, comorbidities, pathology, pancreatic duct size, pancreas texture, baseline quality of life, or operative technique. PD without intraperitoneal drainage was associated with an increase in the number of complications per patient [1 (0-2) vs 2 (1-4), P = 0.029]; an increase in the number of patients who had at least 1 ≥grade 2 complication [35 (52%) vs 47 (68%), P = 0.047]; and a higher average complication severity [2 (0-2) vs 2 (1-3), P = 0.027]. PD without intraperitoneal drainage was associated with a higher incidence of gastroparesis, intra-abdominal fluid collection, intra-abdominal abscess (10% vs 25%, P = 0.027), severe (≥grade 2) diarrhea, need for a postoperative percutaneous drain, and a prolonged length of stay. The Data Safety Monitoring Board stopped the study early because of an increase in mortality from 3% to 12% in the patients undergoing PD without intraperitoneal drainage.
Conclusions: This study provides level 1 data, suggesting that elimination of intraperitoneal drainage in all cases of PD increases the frequency and severity of complications.
Abstract: Since the mid 1980s, the prevalence of liver abscess caused by hypervirulent Klebsiella pneumoniae strain has increased in Asia, particularly in Taiwan and Korea. This strain is mostly K1 or K2 serotype, and has hypercapsular and hypermucoid phenotypes. Most infections are community acquired, and patients rarely have a hepatobiliary disease prior to infection. Clinical manifestations are characterized by fever and high C-reactive protein, and metastatic infections, such as septic emboli in the lung and endophthalmitis and meningitis are frequently observed. Antibiotic resistance is rare. Antibiotic treatment and abscess drainage are needed, and early diagnosis and treatment of endophthalmitis is also important.
Solid Pseudopapillary Neoplasms of the pancreas are rare pancreatic tumors with low grade malignant potential, typically affecting young females.
Small SPNs (< 3cm in diameter) usually appear as completely solid tumors with sharp margins and gradually enhancing, well encapsulated masses in the pancreas and may demonstrate varying amounts of hemorrhage.
Large lesions have mixed solid – cystic components showing early weak enhancement with gradual increase in enhancement in the hepatic venous phase.
Atypical features including extracapsular, as well as parenchymal invasion, simulation of islet cell tumors, calcifications, ductal obstruction, and metastasis are suspicious for malignant degradation.
The tumor is considered unresectable in the event that it invades or encases the aorta, encases >180 degree of the SMA regardless of tumor location in the pancreas, abuts the celiac artery (when the tumor is located in the pancreatic head) or encases >180 degree of the celiac artery (when the tumor is located in the body/tail of the pancreas).
Surgical intervention in the pancreas region is complex and carries the risk of complications, also of vascular nature. Bleeding after pancreatic surgery is rare but characterized by high mortality. This review reports epidemiology, classification, diagnosis and treatment strategies of hemorrhage occurring after pancreatic surgery, focusing on the techniques, roles and outcomes of interventional radiology (IR) in this setting. We then describe the roles and techniques of IR in the treatment of other less common types of vascular complications after pancreatic surgery, such as portal vein (PV) stenosis, portal hypertension and bleeding of varices.
Results: About 10,922 patients undergoing pancreaticoduodenectomy were included for analysis. The most common postoperative complications were DGE (17.3%), POPF (10.1%), incisional SSI (10.0%), and organ/space SSI (6.2%). POPF and DGE were the only complications that demonstrated sizable effects for all clinical and resource utilization outcomes studied. Other complications had sizable effects for only a few of the outcomes or had small effects for all the outcomes.
Results: The gastroduodenal (GDA), anterior superior pancreaticoduodenal (ASPD), and anterior inferior pancreaticoduodenal (AIPD) artery was found in all the cases, whereas the posterior superior pancreaticoduodenal (PSPD) and posterior inferior pancreaticoduodenal (PIPD) artery was present in 93.34% cases. The ASPD artery originated from GDA in all the cases. Two types of variations were observed in the origin of PSPD artery and four types each in the origin of AIPD and PIPD artery. Anatomical and numerical variations were observed in both anterior and posterior arches, posterior arch being absent in 20% cases.
