RESUMEN
EUS-GUIDED biliary drainage (EUS-BD) has recently gained widespread acceptance as a minimally invasive alternative method for biliary drainage. However, the risks of encountering recurrent biliary obstruction (RBO) after EUS-BD have increased due to the growing clinical experience of EUS-BD and prolonged prognosis of the underlying disease. Previous studies have shown that the incidence of RBO following EUS-BD ranges from 11% to 25%. Nevertheless, literature on the efficacy of reintervention of RBO after EUS-GUIDED hepaticogastrostomy (EUS-HGS) and case reports describing the procedural details of endoscopic reintervention following EUS-HGS are lacking.
RESUMEN
Pancreatic cutaneous fistula is a complex condition, making it challenging to achieve favorable outcomes with conservative medical treatment. Surgical interventions often entail surgical risks and postoperative complications. Here, we present a case involving endoscopically guided stent placement between the stomach and the fistula. By internalizing the fistula, patients can potentially remove the external drainage tube, offering a novel endoscopic treatment approach for such cases.

BACKGROUND: Bile duct leaks (BDLs) are serious complications that occurs after hepatobiliary surgery and trauma, leading to rapid clinical deterioration. Endoscopic retrograde cholangiopancreatography (ERCP) is the first-line treatment for BDLs, but it is not clear which patients will respond to this therapy and which patients will require additional surgical intervention. The aim of our study was to explore the predictors of successful ERCP for BDLs. METHODS: A retrospective analysis was conducted using data from six centers' databases. All consecutive patients who were clinically confirmed as BDLs were included in the study. Collected data were demographics, disease severity, and ERCP procedure characteristics. Univariate and multivariate analysis were used to select independent predictive factors that affect the outcome of ERCP for BDLs, and a nomogram was established. Calibration and ROC curves were used to evaluate the models. RESULTS: Four hundred and forty-eight consecutive patients were clinically confirmed as BDLs and 347 were excluded. In the 101 patients included patients, clinical success was achieved in 78 patients (77.2%). In logistic multivariable regression, two independent factors were negatively associated with the success of ERCP: SIRS (OR, 0.183; 95% CI 0.039-0.864; P = 0.032) and high-grade leak (OR 0.073; 95% CI 0.010-0.539; P = 0.010). Two independent factors were positively associated with the success of ERCP: leak-bridging drainage (OR 4.792; 95% CI 1.08-21.21; P = 0.039) and cystic duct leak (OR 6.193; 95% CI 1.03-37.17; P = 0.046). The prediction model with these four factors was evaluated using a receiver-operating characteristic (ROC) curve, which demonstrated an area under the curve of 0.9351. The calibration curve showed that the model had good predictive accuracy. CONCLUSION: Leak-bridging drainage and cystic duct leak are positive predictors for the success of ERCP, while SIRS and high-grade leak are negative predictors. This prediction model with nomogram has good predictive ability and practical clinical value, and may be helpful in clinical decision-making and prognostication.

Biliary-enteric anastomotic stenosis is one of the main long-term complications after pancreaticoduodenectomy, with an incidence of 2%-8%. Although the relevant reports and studies are relatively few, the consequences such as biliary obstruction and refractory cholangitis seriously affect the quality of life of patients. In this case, the patient is not willing to receive conventional surgery again. This paper provides a bridge technique of EUS-guided Biliary Drainage (EUS-BD) to treat biliary-enteric anastomotic stenosis and solve the problem of obstructive jaundice in the patient.
RESUMEN
Chronic pancreatitis in children is an irreversible inflammatory disease, which can cause intractable abdominal pain and abnormal internal and external secretion function of the pancreas, seriously affecting the growth and development of children and the quality of life. ERCP has become the first choice because of its good effect and less trauma. However, the severe stenosis of pancreatic duct caused by chronic pancreatitis may make ERCP more difficult. Here we used the rendezvous technique to assist ERCP to complete the treatment of severe pancreatic duct stenosis and abdominal pain.
RESUMEN
EUS-TASR is a derivative of EUS-BD and serves as a remedy when ERCP fails. EUS-BD technology is commonly used in the diagnosis and treatment of biliary tract and pancreatic diseases with anatomical changes of the digestive tract. This article provides an experience of EUS-TASR and a new challenge in the treatment of common bile duct stones after total gastrectomy.
RESUMEN
Intraductal papillary mucinous neoplasm (IPMN) accounted for 5.0%~7.5% of pancreatic tumors and 21%~33% of cystic tumors. It usually occurs in people aged 60 to 70. The main treatment is surgical excision. The operation method is different according to the location of lesion, so we try our best to achieve accurate treatment. Here, we provide endoscopic ultrasonography combined with ERCP and eyeMax three endoscopic systems, so as to achieve accurate treatment of IPMN, which is recommended to the majority of endoscopists.(AU)

Pancreatic pseudocyst is a complication of pancreatitis, with an incidence of about 5-16% and a incidence of about 20-40% in chronic pancreatitis. There are various ways to treat pancreatic pseudocysts, but the recurrence rate of cysts is as high as 23.9%. There are not many clinical options for the treatment of recurrent pseudocysts, and there is still a high recurrence of pseudocysts after EUS guided drainage alone. We present here a promising endoscopic treatment for patients with recurrent pancreatic pseudocyst.
RESUMEN
It is not uncommon to encounter difficult cannulation during endoscopic retrograde cholangiopancreatography (ERCP), most of which can be performed by double-guide wire, pre-cut and other techniques. Endoscopic ultrasound-guided biliary drainage (EUS-BD) can be used as a remedial solution for ERCP failure. This article provides a very well experience in ERCP combine with EUS-RV technique in cases where the duodenal papilla is located above the medial diverticulum. At the same time, some skills of EUS-RV are provided for endoscopists.

Esophageal cancer (EC) is one of the fatal malignant neoplasms worldwide. Neoadjuvant therapy (NAT) combined with surgery has become the standard treatment for locally advanced EC. However, the treatment efficacy for patients with EC who received NAT varies from patient to patient. Currently, the evaluation of efficacy after NAT for EC lacks accurate and uniform criteria. Radiomics is a multi-parameter quantitative approach for developing medical imaging in the era of precision medicine and has provided a novel view of medical images. As a non-invasive image analysis method, radiomics is an inevitable trend in NAT efficacy prediction and prognosis classification of EC by analyzing the high-throughput imaging features of lesions extracted from medical images. In this literature review, we discuss the definition and workflow of radiomics, the advances in efficacy prediction after NAT, and the current application of radiomics for predicting efficacy after NAT.
RESUMEN
The wedge-tailed green pigeon (Treron sphenurus) has a protective value in the evolution of the family Columbidae. In this study, the complete mitogenome of T. sphenurus from Baise City, China, which represents the first sequenced species of the genus Treron in Tribe Treronini, is reported. This was accomplished using PCR-based methods and a primer-walking sequencing strategy with genus-specific primers. The mitogenome was found to be 18,919 bp in length comprising 37 genes, including 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and one control region. In terms of structure and composition, many similarities were found between the T. sphenurus and Hemiphaga novaeseelandiae (New Zealand pigeon) mitogenomes. This was further supported by phylogenetic analysis showing that T. sphenurus has a close evolutionary relationship with H. novaeseelandiae. The complete mitogenome of T. sphenurus reported here is expected to provide valuable molecular information for further studies on the phylogeny of the genus Treron and for analyses of the taxonomic status of the family Columbidae.
