EUS-guided drainage for gallbladder, bile duct, pancreatic duct, and peripancreatic fluid collection has been performed more frequently in the last decade. The development of dedicated stents and delivery systems for EUS-guided interventions have improved the efficacy and safety of these procedures. Furthermore, the introduction of lumen-apposing metal stents has reduced the complication significantly of endoscopic transmural drainage of pancreatic collections and gallbladder. Recent studies show that EUS-guided drainage of pancreaticobiliary ducts and peripancreatic fluid collection produces good results and low complication rates. This review describes the current position and role of interventional EUS for pancreatobiliary disease in clinical practice.

An isolated pyogenic pancreatic abscess (IPPA) without pancreatitis is extremely rare but can occur in patients with uncontrolled diabetes. This pathologic condition poses a clinical challenge in diagnosis and management because it can be confused easily with a malignancy. Endoscopic ultrasound (EUS) may be a useful diagnostic modality for indeterminate pancreatic lesions and IPPA. Here, we report two cases with elevated carbohydrate antigen 19-9 levels and pancreatic masses on cross sectional imaging. The patients were subsequently diagnosed with IPPA by EUS. EUS-guided drainage was performed successfully and the patients' clinical symptoms and radiologic findings improved. In our experience, EUS and EUS-guided drainage are crucial steps for the diagnosis and management of patients with an indeterminate pancreatic lesion. In addition, EUS-guided drainage has excellent technical and clinical outcomes for the treatment of IPPA.

The main goal of the surgical treatment of maxillofacial deformity is improved esthetic appearance and masticatory function. Recently, the purpose of orthognathic surgery has been focused on esthetic improvement of the patients. The purpose of this study was to investigate the changes in gonial angle to orthognathic surgery. For this study 30 patients were randomly selected. All patients with mandibular prognathism were operated upon with bilateral sagittal split ramus osteotomy and mandibular setback. The patients were cephalmetric lateral radiographs for 1 hear. Lateral cephalmetric radiographs taken preoperatively, over 6-months and 1 year follow up were traced and analysed. The following conclusions were reached. : 1. During following up period for 1 year, the change of gonial angle after orthognathic surgery was decreased, except 3 cases. The mean gonial angle change was decreased from 128.6 degrees(+/-4.83) to 123.4 degrees(+/-5.52) in female(p<0.05). 2. During follow up period for 1 year, the mean gonial angle was decreased after orthognathic surgery from 129.7 degrees(+/-6.47) to 123.3 degrees(+/-7.52), in all male patients(p<0.05). 3. The mean gonial angle changes after orthognathic surgery was about 5.2 degrees in female and 5.4 degrees in male. There was less statistical significance between male and female. 4. The ratio of mandibular setback amount from 6mm to 15mm was 83.3%, and from 1mm to 5mm was 10%.

Spontaneous rupture of a hemorrhagic pancreatic pseudocyst may be life-threatening. Endoscopic ultrasound (EUS)-guided drainage has been reported to be a valuable treatment option for pancreatic pseudocysts. However, its usefulness in the management of a ruptured pancreatic pseudocyst is limited. We report a rare case of a spontaneous rupture of a hemorrhagic pancreatic pseudocyst in a patient with chronic pancreatitis, which was successfully treated with EUS-guided gastrocystostomy with a fully covered self-expandable metallic stent.

The length, the frequency, and the methods of surveillance for intraductal papillary mucinous neoplasm (IPMN) of the pancreas are still debating. According to the recent guidelines, IPMN is stratified into “high-risk stigmata” or absolute indication and “worrisome features” or relative indication as a guide in managing these patients, either those with resection of the lesion or those under surveillance. The risk of malignant transformation was quite low for branch duct-IPMNs without worrisome features or high risk stigmata. However, because the incidence rate of pancreatic cancer in these patients increase linearly with time, continued long-term surveillance is therefore important for patients with low-risk, as well as higher-risk, IPMN.Considering the high prevalence of malignancy, main duct-IPMN should be treated by surgical resection. Among patients with these type IPMNs, segmental dilatation of the main pancreatic duct without any mural nodules and larger than 10 mm of main pancreatic duct might not be immediately resected and need very careful examination and observation. The risk related to a major pancreatic resection must balance the risk of surveillance in patients with IPMN of the pancreas who have co-morbidity and are elderly.

Mirizzi syndrome is a rare complication of gallbladder disease that can be difficult to treat. In particular, endoscopic treatment often fails because of the inability to access or to capture the impacted cystic duct stone. We report a case of Mirizzi syndrome grade III that was successfully managed by digital single-operator peroral cholangioscopy-guided electrohydraulic lithotripsy with endoscopic nasogallbladder drainage and interval laparoscopic cholecystectomy. Based on our experience, digital single-operator peroral cholangioscopy-guided electrohydraulic lithotripsy with endoscopic nasogallbladder drainage is a feasible minimally invasive approach for the management of high-grade Mirizzi syndrome.

There are still debated about surveillance interval, duration, diagnostic modality and treatment for intraductal papillary mucinous neoplasm (IPMN) of the pancreas. In recent guidelines, ‘high risk stigmata (HRS)’ and ‘worrisome feature (WF)’ are defined as predictive factors for malignancy in IPMN. IPMNs with HRS and main duct- IPMN are more likely to accompany malignancies, thus require surgery. However, in the case of only WF, since the risk of malignancy is different for each factor, the management decision can be variable according to the number of overlapping WFs. In addition, for segmental main pancreatic duct dilatation without enhancing mural nodules, careful surveillance might be considered rather than immediate surgery. In IPMN patients with elderly or severe comorbidities, treatment strategy should be determined based on surgical and malignant risk assessment. To date, the natural course of IPMN patients with HRS and WF is not well understood, thus further studies with a large number of patients are needed.
