We report two cases, a 58-year-old male and a 60-year-old female with acute aortic occlusion probably ascribable to intracardiac thrombosis associated with atrial fibrillation. Thrombectomy was performed at about 5.5 hours and 4 hours respectively, after the onset of occlusion, and revascularization was successful. To prevent MNMS after revascularization, about 2, 000ml of blood was taken from the femoral vein of the male patient, and 1, 000ml of blood from the female patient, and this blood was returned in the form of abluted erythrocytes in transfusion through a cell saver to the patients. We suspected slight myoglobinuria after the operations, but they did not develop MNMS because a urine volume of about 3, 000ml was maintained by administration of infusion solution and diuretics and by replenishment of electrolytes and correction of acidosis. It was concluded that the technique involving the removal of a large volume of blood from distal veins and its transfusion through a cell saver was effective in preventing MNMS.

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.

Purpose: The simple conversion ratio of 1:1:1/50 between oxycodone injection (OXJ), morphine injection and fentanyl injection is used at Saga-Ken Medical Centre Koseikan. However, there are no studies on the validity of the simple conversion ratio. Methods: A total of 18 patients with opioid switching to OXJ using the simple conversion ratio were reviewed in this investigation. We surveyed the change in the numeric rating scale (NRS) and adverse effects before and after opioid switching. Result: The average period needed to reach a stable dose of OXJ was 0.6 days. The reasons of opioid switching to OXJ were the uncontrolled cancer pain in 11 patients, the impossibility of oral administration in 6 patients, the drowsiness in 1 patient. The average NRS decreased from 3.3 to 1.1 in 11 patients with uncontrolled cancer pain (p=0.007). No obvious change in the NRS was observed in 6 patients with the impossibility of oral administration. In 18 patients, there was no significant difference in adverse effects before and after opioid switching. Conclusion: These results indicate that the simple conversion ratio could be safety for opioid switching between OXJ and other opioid in cancer pain treatment.

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.

We have reported that many chrysanthemum- and lettuce-growers have dermatitis caused by juice of the leaves of these plants and that this dermatitis is caused by an allergic mechanism. In arecent questionnaire on the cause of this dermatitis, half the farmers answerd that it was due to agricultural chemicals. Therefore, we tested the farmers by skin patch tests with several widely used chemicals. In the tests, daconil gave the strongest reaction, results being positive in 60% of the farmers. Daconil was very irritative and phototoxic, the percentage of positive reactions in the patch test with 800 times diluted daconil solution of the concentration commonly used being about 30% after 48 hours and about 60% at 48 hours after peeling off the patch.
The parcentage of positive reactions in the skin patch test with several fractions of chrysanthemums on chrysanthemum-growers were significantly higher than non-farm-workers. Similary, tests with allergen extracted from lettuce showed a significantly higher percentage incidence in lettuce -growers than in other subjects. The patch test with 4000 times diluted daconil solution showed ahigher incidence in farmers than in other subjects. Therefore, 4000 times diluted daconil solution seems to cause allergic contact dermatitis in farmers, and as farmers reported, dermatitis seems to be caused by allergy to farm products, and the irritability, phototoxicity and allergenicity of TPN (Daconil).

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.

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.

This study aimed to clarify the effects of carbohydrate mouth rinse on exercise performance. We examined the effect of mouth rinse on fatigability. Thirty healthy male college students completed three trials with non mouth rinse (CON), mouth rinse intervention of 6% glucose (GMR), and artificial sweetener (PLA). Handgrip exercise was performed as a fatigue task. The subjects performed a 10-seconds maximal voluntary contraction (MVC) followed by a 40% MVC rhythmic grasping movement for 14 per minutes, followed by a 4-seconds rest. This set of exercises was performed for a total of ten sets. Mouth rinse was performed from the 5th set to the 10th set. The subjects were divided into three groups: L, M, and S, according to the degree of decrease in MVC due to fatigue in CON. The effect was evaluated using the rate of change in MVC after the mouth rinse. The evaluation was performed for each trail and group. In the L group, mouth rinse significantly improved the rate of change of MVC compared with the other trials (GMR vs. CON: P = 0.002; PLA vs. CON: P = 0.042). A significant trend was observed in the M (GMR vs. CON: P = 0.062), but not in the S. In conclusion, the effects of mouth rinse differed depending on fatigability in isometric hand grip performance, with mouth rinse inhibiting the decrease of motor fatigue. In addition, it was suggested that the sweetness of carbohydrates may have an effect on mouth rinse.

BACKGROUND/AIMS: Groove pancreatitis (GP) is an uncommon disease involving the pancreaticoduodenal area. Possible pathogenesis includes obstructive pancreatitis in the duct of Santorini and impaired communication with the duct of Wirsung, minor papilla stenosis, and leakage causing inflammation. Limited data regarding endoscopic treatment have been published. METHODS: Seven patients with GP receiving endoscopic treatment were reviewed. The morphology of the pancreatic duct was evaluated by a pancreatogram. Endoscopic dilation of the minor papilla and drainage of the duct of Santorini were performed. RESULTS: There were two pancreatic divisum cases, one ansa pancreatica case and four impaired connections between the duct of Santorini and the main pancreatic duct. Three to 31 sessions of endoscopy, with 2 to 24 sessions of transpapillary stenting and dilation, were performed. Interventions through the minor papilla were successfully performed in six of seven cases. The pancreatic stenting duration ranged from 2 to 87 months. Five patients with evidence of chronic pancreatitis (CP) tended to receive more endoscopic interventions than did the two patients without CP (2–24 vs 2, respectively) for GP and other complications associated with CP. CONCLUSIONS: Disconnection or impairment of communication between the ducts of Santorini and Wirsung was observed in all cases of GP. No surgery was required, and endoscopic minor papilla dilation and drainage of the duct of Santorini were feasible for the treatment of GP.
