BACKGROUND Endoscopic biliary stenting with a plastic stent is often performed to prevent impaction of common bile duct (CBD) stones. The therapeutic effect of a plastic stent placement in terms of reduction in stone size and number has not been established. OBJECTIVE The aim of this study was to study the effect of biliary stenting as therapy for CBD(More)
AIM To study the safety and effectiveness of propofol sedation for outpatient colonoscopy. METHODS Propofol was given by bolus injection with an age-adjusted standard protocol consisting of 60 mg for patients < 70 years old, 40 mg for patients age 70-89 years, and 20 mg for those ≥ 90 years, and additional injections of 20 mg propofol were given up to a(More)
AIM Colonoscopy may need to be rescheduled because of inadequate bowel preparation. We evaluated the effectiveness of colonoscopic enema as rescue for an inadequate 1-day bowel preparation before colonoscopy. METHOD Patients referred for afternoon colonoscopy were prospectively enrolled in the study during a 1-year period. Patients took bowel preparation(More)
BACKGROUND Obturator hernia is rarely recognized before surgical intervention, since it is relatively infrequent and its definitive diagnosis is difficult. To change this situation, we introduced ultrasound examination in 1993 for differential diagnosis of strangulated obturator hernia among patients with bowel obstruction of unknown cause. PATIENTS AND(More)
Abdominal aortic aneurysms (AAAs) are characterized by structural deterioration of aortic wall leading to progressive dilatation. The histopathological changes in AAAs are particularly evident within the elastic media, which is normally comprised mainly of vascular smooth muscle cells (SMCs). There are vascular myosin heavy chain (MHC) isoforms; SM2 is(More)
AIM Colonoscopy provides imperfect protection against colorectal cancer (CRC). In an attempt to improve cancer detection we evaluated the clinical features of invasive CRC detected within 5 years of a negative colonoscopy. METHOD The details of colonoscopies performed in a rural hospital in Japan were prospectively recorded at the time of the examination.(More)
We report the case of a video capsule endoscope lodged within a Zenker diverticulum. The system that was equipped with a real-time viewer showed an unchanging image unlike esophageal or gastric mucosa, suggesting that the capsule was elsewhere. The presence of cervical discomfort suggested video capsule retention in a Zenker diverticulum. The capsule was(More)
AIM Endoscopic decompression of malignant colorectal obstruction is often dealt with using expandable metallic stents. Endoscopic decompression of benign large bowel obstruction is more difficult. We report the technique and outcome of transanal endoscopic decompression for benign large bowel obstruction. METHOD From January 2001 to June 2010, endoscopic(More)
