Abstract. Introduction:. Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is a novel drainage option for patients with an inaccessible papilla. Although EUS-HGS has clinical benefits in patients for whom endoscopic retrograde cholangiopancreatography (ERCP) has failed, the rates of adverse events (AEs) associated with EUS-HGS, such as bile peritonitis and stent migration, are higher than for other procedures. The development of a dedicated system for EUS-HGS is therefore desirable to reduce the rate of AEs. We developed a dedicated system for EUS-HGS (HG01 system) which is composed of a 19-gauge needle, 0.025-inch guidewire, a thin delivery system for tract dilation, and an antimigration metal stent. This study is designed to evaluate the efficacy and safety of EUS-HGS using the HG01 system in malignant biliary obstruction. Methods/design:. This is a single-arm multicenter prospective study involving 40 patients across six tertiary centers in Japan. Patients with an unresectable malignant biliary obstruction in whom biliary drainage with ERCP failed, is not possible, or is very difficult will be registered in the study. The primary endpoint is the clinical success rate. The secondary endpoints are the technical success rate, procedure-related AE rate, procedure time, procedure success rate using only the HG01 system, stent patency rate, re-intervention success rate, re-intervention method, survival rate, and distance of movement of the stent position. Discussion:. We expect use of the HG01 system to reduce the rate of AEs during EUS-HGS, especially bile leakage and stent migration. If the efficacy and safety of EUS-HGS using the HG01 system is confirmed in the present study, it is likely to be considered the first-choice device for use during EUS-HGS.

Abstract. Introduction:. Endoscopic submucosal dissection (ESD) is an advanced therapeutic technique for en bloc resection of superficial gastrointestinal neoplasms. Although gastric ESD is minimally invasive and provides favorable outcomes, it is technically difficult and requires a long procedure time for dissection. The traction-assisted approach overcomes some of the difficulties of gastric ESD, but its ability to reduce the procedure time remains unclear. The traction-assisted approach using dental floss and a clip did not reduce procedure time in the total population, but it reduced procedure time for lesions limited to the greater curvature of the upper or middle of the stomach. Although the traction direction of the clip-with-line method may be limited to the oral side via the cardia, EndoTrac ESD may provide flexible traction at any time during the procedure. This prospective randomized control study has been designed to compare the efficacy and safety of EndoTrac and conventional gastric ESD. Methods/design:. This multicenter, randomized control trial will enroll 150 patients at 2 hospitals in Japan undergoing EndoTrac or conventional ESD for gastric epithelial neoplasia. Patients with a single gastric epithelial neoplasm who meet the inclusion and exclusion criteria will be randomized to EndoTrac or conventional ESD. Patients will be randomized by a computer-generated random sequence with stratification by operator experience, tumor size, tumor location, and institution. The primary endpoint will be ESD procedure time, defined as the time from the start of the submucosal injection to the completion of resection. Other outcomes will include the rates of adverse events and pathological curability Discussion:. The ability of EndoTrac ESD to reduce the long procedure time and/or adverse events observed with conventional ESD can not only reduce physical stress on the patient, but can also reduce length of hospital stay and medical costs. Reduced technical difficulty will contribute to the widespread adoption of this ESD technique worldwide. Trial registration:.

ABSTRACT: Background: Ninjin'yoeito, a traditional Japanese herbal medicine, is used to prevent fatigue, loss of appetite, and coldness of limbs. Fatigue is an especially common issue during chemotherapy and can affect quality of life and the ability to complete scheduled treatment. Objectives: This prospective exploratory trial evaluates the efficacy of ninjin'yoeito for fatigue in patients undergoing nab-paclitaxel plus gemcitabine therapy for unresectable pancreatic cancer. The primary end point was evaluation of fatigue according to Functional Assessment of Chronic Illness Therapy-Fatigue score during 2 courses of nab-paclitaxel plus gemcitabine therapy. Secondary end points included evaluation of dose intensity, appetite loss using numerical rating scale, and peripheral neuropathy using a patient neurotoxicity questionnaire. Methods: We compared data from this interventional trial with a prior observational trial without administration of ninjin'yoeito with identical definition of end points (UMIN000021758). Thirty patients were required by the study. Results: Threshold mean of Functional Assessment of Chronic Illness Therapy-Fatigue score across 8 weeks during chemotherapy was under 5.3 (P = 0.002). Secondary end points did not reveal any specific patterns in appetite loss or degree of pain. No significant changes in patient neurotoxicity questionnaire concerning sensory/motor disorders were observed, but the mean (SD) incidence of patients with sensory disturbance was higher between the fifth and eighth weeks (8.8 [1.26]) than during the first and fourth weeks (4.8 [0.96]) (P = 0.003). Clinically significant adverse reactions of ninjin'yoeito were not observed. Conclusions: Ninjin'yoeito may be useful for improving the symptoms of fatigue caused by nab-paclitaxel plus gemcitabine in patients with unresectable pancreatic cancer.
