Endoscopic ultrasound (EUS)-guided hepaticogastrostomy (HGS) is widely performed not only as an alternative to transpapillary biliary drainage, but also as primary drainage for malignant biliary obstruction. For anatomical reasons, this technique carries an unavoidable risk of mispuncturing intrahepatic vessels. We report a technique for troubleshooting EUS-guided portal vein coiling to prevent bleeding from the intrahepatic portal vein after mispuncture during interventional EUS. EUS-HGS was planned for a 59-year-old male patient with unresectable pancreatic cancer. The dilated bile duct (lumen diameter, 2.8 mm) was punctured with a 19-gauge needle, and a guidewire was inserted. After bougie dilation, the guidewire was found to be inside the intrahepatic portal vein. Embolizing coils were placed to prevent bleeding. Embolization coils were successfully inserted under stabilization of the catheter using a double-lumen cannula with a guidewire. Following these procedures, the patient was asymptomatic. Computed tomography performed the next day revealed no complications.

Background/Aims:
The Japan Gastroenterological Endoscopy Society (JGES) has published guidelines for gastroenterological endoscopy in patients undergoing antithrombotic treatment. These guidelines classify endoscopic ultrasound-guided biliary drainage (EUS-BD) as a high-risk procedure. Nevertheless, the bleeding risk of EUS-BD in patients undergoing antithrombotic therapy is uncertain. Therefore, this study aimed to assess the bleeding risk in patients undergoing antithrombotic therapy.
Methods:
This single-center retrospective study included 220 consecutive patients who underwent EUS-BD between January 2013 and December 2018. We managed the withdrawal and continuation of antithrombotic agents according to the JGES guidelines. We compared the bleeding event rates among patients who received and those who did not receive antithrombotic agents.
Results:
A total of 18 patients (8.1%) received antithrombotic agents and 202 patients (91.8%) did not. Three patients experienced bleeding events, with an overall bleeding event rate of 1.3% (3/220): one patient was in the antithrombotic group (5.5%) and two patients were in the non-antithrombotic group (0.9%) (p=0.10). All cases were moderate. The sole thromboembolic event (0.4%) was a cerebral infarction in a patient in the non-antithrombotic group.
Conclusions
The rate of EUS-BD-related bleeding events was low. Even in patients receiving antithrombotic therapy, the bleeding event rates were not significantly different from those in patients not receiving antithrombotic therapy.

Probe-based confocal laser endomicroscopy is an endoscopic technique that enables in vivo histological evaluation using fluorescent pigment. The ability to diagnostically differentiate between benign and malignant biliary disease using the “CholangioFlexTM”, a dedicated biliary device, has been reported. However, the Miami and Paris classifications, used as diagnostic criteria, mainly evaluate findings in the submucosa, and visualizing the epithelium as the main site of lesions remains difficult. To address this problem, we verified the imaging findings and diagnostic ability of three types of probes: CholangioFlexTM, GastroFlexTM, and AlveoFlexTM. With GastroFlexTM, the clear mucosal epithelium was observed, and differential diagnoses as benign/malignant could be made based on epithelial findings. GastroFlexTM may be a good first-choice probe for probe-based confocal laser endomicroscopy of biliary diseases, and a new diagnostic classification based on bile duct epithelial findings may provide useful criteria independent of the Miami or Paris classifications.

An 86-year-old woman visited our hospital at 20:00 with the chief complaint of right hip joint pain that had started at around 19:30. The abdomen was soft and slightly bloated, and there was tenderness in the right hip joint. Computed tomography (CT) revealed protrusion of the small intestine through the right obturator foramen, and right-sided impacted obturator hernia was diagnosed. Intestinal necrosis was unlikely because her symptoms had started only a short time earlier, so manual reduction was performed. The right hip joint pain was rapidly alleviated, and CT confirmed release of the incarcerated bowel. Elective laparoscopic repair was then performed. Hemorrhagic ascites in the abdominal cavity, but no obvious intestinal ischemia, was evident. Intestinal dilation was relieved, enabling us to perform surgical maneuvers in a good surgical field. The postoperative course was favorable, and there has been no recurrence as of 2 years 11 months after surgery. Obturator hernia is common in elderly women, who often have several comorbidities. Avoidance of emergency surgery by manual reduction is therefore significant, and laparoscopic surgery that enables assessment and treatment of the contralateral side is beneficial.

The patient was a 73-year-old man. He had sustained a spinal cord injury in a work-related accident at 40 years of age and was living with lower body paralysis. He had defecation disorder due to poor intestinal peristalsis of the sigmoid colon. Colostomy was indicated because the defecation disorder had worsened to the extent that hospital management was required. We selected a laparoscopic approach for two reasons. First, at the time of the accident, he had undergone thoracotomy and laparotomy to treat diaphragm injury and we expected that adhesions would need to be removed in the abdominal cavity. Second, patients with spinal cord injury are prone to poor bowel peristalsis, and minimally invasive surgery should be used to prevent postoperative paralytic ileus. The operation was performed with three ports. Adhesions of the transverse colon, omentum, and abdominal wall were peeled off, the transverse colon was mobilized, and a transverse colostomy was created in the upper right abdomen. The postoperative course was favorable, and he resumed eating on postoperative day 2. Laparoscopic colostomy for patients with spinal cord injury and defecation disorder can be a safe and effective technique for improving quality of life.

Patient 1 was a 73-year-old woman with chief complaints of abdominal pain and prolapse of bowel through the anus. About 10 cm of the intestine had prolapsed through the anus, and a mass was observed at the invasive front. Computed tomography (CT) revealed the classic target sign of an intussusceptum inside an intussuscipiens, where the sigmoid colon had intussuscepted into the rectum. Patient 2 was a 92-year-old woman who presented with a chief complaint of melena. About 5 cm of the intestine had prolapsed through the anus, and a mass was observed at the invasive front. CT showed the classic target sign in the rectum. Based on physical examination and CT findings, both cases were diagnosed as intussusception caused by progression of colorectal cancer. Manipulative reduction was attempted before surgery, but neither intussusception could be reduced and thus Hartmann’s operation was performed for both patients. Patient 1 had an uneventful postoperative course and was discharged on hospital day 36. Patient 2 developed prolonged paralytic ileus due to unsuccessful mobilization and was discharged on hospital day 80. Abdominoperineal resection is required for irreducible prolapse of intussusception through the anus due to colorectal cancer, and this invasive procedure can cause complications. Many patients with this condition are elderly adults with weak pelvic supporting tissue, and thus treatment suited to each individual patient must be selected.

【Introduction】One of the effects of the hot spring provides worm temperature. This effect raises temperature, and temperature control function operates and causes increase of the bloodstream. This time, these changes examined the thing by the size of the bathtub and the spring quality of the hot spring. 【Subjects and Methods】The subjects were 10 healthy adult men (mean age: 25.2 years). They bathed for 10 min in bathtubs at 42°C. The enforcement used plunge bath (approximately 1,700 L: simple alkaline hot spring) and home bathtub (approximately 300 L: hot water, 0.1% artificially chlorinated spring). Measurement item of the maximum arterial blood flow rate using the Ultrasonic Rheometer Smart Doppler 45, deep body temperature using the deep body temperature monitor core temperature CM-210, I compared each value 10 min during the bathing, and during a 10-min, 20-min, 30-min resting period after bathing, furthermore, I found the conjugation on each condition resting period after bathing. 【Result】The rise in deep body temperature and maximum arterial blood flow rate showed the result that a hot spring of the plunge bath was more meaningful than the value of the home bathtub after 10 min of bathing. The deep body temperature of the hot spring of the plunge bath significantly rose from bathing 3 min after. In deep body temperature with the resting period after bathing, in the hot spring of the plunge bath, a meaningful rise was maintained in hot water 13 min for population chloride spring 16 min of the home bathtub for 15 min. 【Discussion】In thinks that a population spring let you maintain a temperature rise that it disturbs a drop of the water temperature by abundant quantity of water in the plunge bath that hot spring plunge bath had a bigger deep body temperature rise, maximum arterial blood flow rate than home bathtub, and the deep body temperature rise in the home bathtub was continued.

BACKGROUND/AIMS: Recent research has highlighted the importance of interactions between commensal fungi and intestinal inflammation. However, there are few studies investigating whether commensal fungi contribute to inflammation in patients with Crohn's disease (CD). The aim of this study is to investigate reveal interactions between commensal fungi and host immune cells in CD. METHODS: CD14-positive monocytes were isolated from peripheral blood mononuclear cells from healthy human volunteers and then differentiated in the presence of macrophage colony-stimulating factor (M-CSF) (referred to as M-macrophages, M-Mϕs) or M-CSF and interferon-γ (IFN-γ) (referred to as M-gamma macrophages, Mγ-Mϕs). Cytokine production by these in vitro differentiated macrophages in response to β-(1,3)-glucan was analyzed by flow cytometry. Expression of Dectin-1 was examined using flow cytometry, western blotting, and quantitative reverse transcription-polymerase chain reaction. Cytokine production by in vitro differentiated macrophages in response to β-(1,3)-glucan was measured in the presence of an anti-Dectin-1 receptor antagonist, anti-Syr, or an anti-Fas-1 antibody. Cytokine production by lamina propria mononuclear cells (LPMCs) derived from CD patients in response to β-(1,3)-glucan was also analyzed. RESULTS: Mγ-Mϕs produced a large amount of tumor necrosis factor-α (TNF-α) and interleukin-6 in response to β-(1,3)-glucan. Dectin-1 expression was significantly higher in Mγ-Mϕs than in M-Mϕs. The increase in TNF-α production by Mγ-Mϕs stimulated with glucan was reversed by blocking Dectin-1, Syr or Fas-1. LPMCs derived from CD patients stimulated with β-(1,3)-glucan produced significantly higher amount of TNF-α than LPMCs derived from UC patients. CONCLUSIONS: These results suggest that commensal fungal microbiota may contribute to the pathogenesis of CD by inducing macrophages-derived pro-inflammatory cytokines.

Komono Town is a well-known spa and health resort in Mie Prefecture. Komono Town has been seeking ways to promote the activities of hot spring area and health resources in surrounding areas. As part of these efforts, Komono Town has developed town-walk programs to promote the health of local residents. In this study, focusing on effect of walking on relaxation, we compared levels of stress hormones and emotional scores obtained before and after walking. After giving their informed consent, adult participated in two walking programs, each for a distance of approximately 7 km. Salivary cortisol levels were measured before and after intervention. In addition, the Mood Check List-Short form. 2 (MCL-S.2) and a Visual Analog Scale (VAS) were used to rate emotions before and after intervention. In both programs, walking tended to lower levels of salivary cortisol than resting. Low levels of cortisol, an adrenocortical hormone released during a state of predominantly sympathetic nervous activity, are thought to reflect mental relaxation; our result implies that the walking program enhanced relaxation in subjects. In addition, both MCL-S.2 and VAS rating showed that the subjects tended to feel better, more relaxed and less anxious after intervention. These findings suggest that the walking programs are beneficial human body thorough, for example, enhanced relaxation.
