The purpose of this study was to analyze the socioeconomic factors influencing patient discharge destination and the length of their hospital stay. We investigated 83 consecutive stroke patients admitted to our rehabilitation ward between January 1 and December 31, 2008. The mean age was 68.1 years old, the mean length of stay was 86.1 days, and 57% were men. The outcome for this study was the patient discharge destination, defined as home or a nursing home type of facility. To examine the predictors of the discharge destination, we collected data including patient age, sex, total Functional Independence Measure (FIM) scores at discharge, ‘living alone’, ‘over 65 years old’, ‘requiring public assistance’, and ‘having a family member at home who requires nursing care’. In all, 69 patients were able to return home, and 14 patients were discharged to a nursing home type of facility. The home group showed a higher total FIM score (p<0.001). Logistic regression analysis showed that two factors, ‘living alone’ and ‘having a family member at home who requires nursing care’, adversely affected patient discharge to home. Also, the length of stay was longer among those patients who required public assistance (p<0.01). This study suggests that it is harder for patients to be discharged back to their homes who have these factors : ‘having a family member at home who requires nursing care’ and ‘living alone’. Additionally, having the patient characteristic of ‘requiring public assistance’ could prolong the length of hospital stay.

Using the DDG-2001 pulse dye densitometer, cardiac output (CO) and circulating blood volume (BV) were determined before and after the operation, and its accuracy and the significance of postoperative management were studied. Referring to 14 cases undergoing open heart surgery, CO and BV were determined using the DDG-2001 before application of the cardiopulmonary bypass and immediately, 4h and 12h after the operation. The level of CO was compared with that determined by the thermodilution method, and the level of BV with that calculated from hemoglobin levels determined before and after the cardiopulmonary bypass application and the priming volume in the circuit. Further, body fluid balance after the operation was calculated, and its relation to BV was studied. As to the correlation coefficient and inclination of the regression line, they were 0.77 and 0.849 with CO, and 0.821 and 0.844 with BV, respectively. Upon completion of the operation BV decreased, but increased again 4h and 12h later, although the body fluid balance was negative. CO and BV determined by the pulse dye densitometry favorably correlated with those determined by other methods. Immediately after the operation BV decreased, but then increased in the course of time, although the body fluid balance was negative.

A 84-year-old man was admitted with an abdominal tumor. Prosthetic graft replacement between the aorta and the left external iliac artery was performed 17 years previously. CT scan and angiography showed a large anastomotic pseudoaneurysms at the sites of proximal and distal anastomosis. A Y graft prosthesis replacement was performed. The size of the proximal anastomotic pseudoaneurysm was 7×6×5cm, and that of the distal anastomotic pseudoaneurysm was 15×10×10cm. They resulted from cutting at anastomosis. Large anastomotic pseudoaneurysms at both sites is rare.

Placement of a plastic or metal stent via endoscopic retrograde cholangiopancreatography (ERCP) currently serves as the first-line procedure for obstructive jaundice and acute cholangitis. Dysfunction of the biliary stent causes recurrence of symptoms and often requires reinterventions and hospitalizations. Therefore, duration of stent patency is commonly used as the primary endpoint in clinical studies of biliary stents. However, owing to considerable heterogeneity between studies in reporting of biliary stent patency, it has been difficult to compare and integrate results of independent studies. There has been between-study heterogeneity in definitions of stent patency, statistics reported for survival curves of stent patency, and methods to treat censored cases. In addition to stent occlusion, stent migration is a major cause of recurrent biliary obstruction after covered metal stent placement, which further complicates the reporting of stent patency. Reporting of functional success and adverse events has been also inconsistent between the studies. From the perspective of evidence-based medicine, the variations in the definitions of outcome variables potentially hinder robust meta-analyses. To overcome the issues due to the lack of outcome reporting guidelines on the topic, the TOKYO criteria 2014 for reporting outcomes associated with endoscopic transpapillary placement of biliary stents have been proposed. Due to their comprehensiveness, the TOKYO criteria can be readily utilized to evaluate various types of biliary stent placement using ERCP, irrespective of types of stents and location of biliary stricture. In this article, we review the TOKYO criteria as a standardized reporting system for endoscopically-placed biliary stents. We also discuss potential controversial issues in the application of the TOKYO criteria. Given that endoscopic ultrasound-guided biliary drainage is increasingly utilized for cases with failed ERCP or altered gastrointestinal anatomy, we further propose a potential application of the TOKYO criteria to reporting of outcomes of this procedure.

Stent occlusion and cholangitis are common complications after endoscopic biliary stenting caused by duodenobiliary refluxes and food impaction. To prolong the stent patency, the concept of stenting above the papilla, so-called inside stent, has been developed. Various studies of the inside stent in the treatment of both benign and malignant biliary obstruction have been published, with a promising result. However, most studies were retrospective, with wide variation of stent type and the etiology of biliary obstruction. This review aims to summarize the principle, evidence, and the usefulness of inside biliary stent.

Endoscopic ultrasound-guided biliary drainage (EUS-BD), EUS-guided choledochoduodenostomy (EUS-CDS), and EUS-guided hepaticogastrostomy (EUS-HGS) can effectively palliate obstructive jaundice, but have not been well established yet. The incidence of complications is about 30% in EUSBD and higher for EUS-HGS. Several complications have been reported such as bleeding, perforation and peritonitis. Bleeding occurs due to puncture of portal vein, hepatic vein and artery, and we should use color Doppler. When a cautery dilator is used for fistula dilation, burn effects may cause delayed bleeding. Endoscopic hemostasis is only effective for anastomotic bleeding and embolization with interventional radiology technique is required for pseudo aneurysm. There are some types of perforation: failed stent placement after puncture or fistula dilation, double puncture during CDS procedure, and stent migration. Peritonitis with perforation requires surgery and can be fatal. Stent migration before mature fistula formation causes severe peritonitis because EUS-BD makes fistula between two unattached organs. Stents with flaps or long covered self-expandable metallic stents (cSEMSs) are effective to prevent migration. Recent development of lumen apposing stents may reduce early migration in EUS-CDS. Peritonitis without migration can be due to 1) leakage of bile juice or gastric/duodenal contents during EUS-BD or 2) leakage along the placed stent. We should make procedure time as short as possible, and cSEMSs reduce bile leak along the stent by occluding the dilated fistula. In summary, we should understand the mechanism of complications and the technique to prevent and manage complications. Development of dedicated devices to increase the success rate and reduce complications is required.

BACKGROUND/AIMS: Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is useful for the pathological diagnosis of pancreatic masses, but patients are susceptible to severe bleeding and perforation. Because the incidence and severity of these complications have not been fully evaluated. METHODS: We aimed to evaluate severe bleeding and perforation after EUS-FNA for pancreatic masses using large-scale data derived from a Japanese nationwide administrative database. RESULTS: In total, 3,090 consecutive patients from 212 low- to high-volume hospitals were analyzed. Severe bleeding requiring transfusion or endoscopic treatment occurred in seven patients (0.23%), and no perforation was observed. No patient mortality was recorded within 30 days of EUS-FNA. The rate of severe bleeding in low-volume hospitals was significantly higher than that in medium- and high-volume hospitals (0.48% vs 0.10%, p=0.045). CONCLUSIONS: Severe bleeding and perforation following EUS-FNA for pancreatic masses are rare, and the procedure is safe.

Percutaneous transhepatic biliary drainage (PTBD) is an established procedure for biliary obstruction. However, duodenobiliary or jejunobiliary reflux of the intestinal contents through a PTBD catheter sometimes causes recurrent catheter obstruction or cholangitis. A 64-year-old female patient with a history of choledochojejunostomy was referred to our department with acute cholangitis due to choledochojejunal anastomotic obstruction. Emergent PTBD was performed, but frequent obstructions of the catheter due to the reflux of intestinal contents complicated the post-PTBD course. We therefore introduced a catheter with an antireflux mechanism to prevent jejunobiliary reflux. A commercially available catheter was modified; side holes were made at 1 cm and 5 to 10 cm (1 cm apart) from the tip of the catheter, and the catheter was ligated with a nylon thread just proximal to the first side hole. Using this novel "antireflux PTBD technique," jejunobiliary reflux was prevented successfully, resulting in a longer patency of the catheter.

In the present study, we investigate the expression profile of the epidermal growth factor receptor family, which comprises EGFR/ErbB1, HER2/ErbB2, HER3/ErbB3 and HER4/ErbB4 in oral leukoplakia (LP). The expression of four epidermal growth factor receptor (EGFR) family genes and their ligands were measured in LP tissues from 14 patients and compared with levels in 10 patients with oral lichen planus (OLP) and normal oral mucosa (NOM) from 14 healthy donors by real-time polymerase chain reaction (PCR) and immunohistochemistry. Synchronous mRNA coexpression of ErbB1, ErbB2, ErbB3 and ErbB4 was detected in LP lesions. Out of the receptors, only ErbB4 mRNA and protein was more highly expressed in LP compared with NOM tissues. These were strongly expressed by epithelial keratinocytes in LP lesions, as shown by immunohistochemistry. Regarding the ligands, the mRNA of Neuregulin2 and 4 were more highly expressed in OLP compared with NOM tissues. Therefore, enhanced ErbB4 on the keratinocytes and synchronous modulation of EGFR family genes may contribute to the pathogenesis and carcinogenesis of LP.

1. 5-HT inhibits spontaneous fluid secretion as well as stimulated secretion with secretin (cAMP mediated) or ACh (Ca2+ mediated) in the isolated guinea pig pancreatic ducts. 2. The inhibitory effect of 5-HT is reversible and is dependent on the concentration in the range 0.01-0.1 microM, which is much lower than those that affect intestinal motility and secretion. 3. The 5-HT3 receptor in duct cells appears to mediate the inhibitory effect of 5-HT. 4. [Ca2+]i is unlikely to mediate the inhibitory effect of 5-HT.
