Abstract Ethnopharmacological relevance Goshajinkigan (GJG), a traditional Japanese Kampo formula, has been shown to exhibit several pharmacological actions, including antinociceptive effects. Processed aconite root (PA), which is considered to be an active ingredient of GJG, has also been demonstrated to have an ameliorative effect on pain, such as diabetic peripheral neuropathic pain. We recently identified neoline as the active ingredient of both GJG and PA that is responsible for its effects...

Abstract Background Abdominoperineal resection (APR) is a standard surgical technique for low rectum cancer with a low recurrence rate. There are some problems associated with APR such as perineal hernia and perineal surgical site infection. Recently, the prophylactic efficacy of negative pressure wound therapy (NPWT) for surgical site infection has been reported. Herein, we analyzed the efficacy of in situ pelvic floor reconstruction combining levator ani suture and NPWT after APR for perineal ...

Importance Randomized clinical trials of vitamin D supplementation for secondary prevention in patients with cancer are needed, given positive results of observational studies. Objective To determine whether postoperative vitamin D 3 supplementation can improve survival of patients with digestive tract cancers overall and in subgroups stratified by 25-hydroxyvitamin D (25[OH]D) levels. Design, Setting, and Participants The AMATERASU trial, a randomized, double-blind, placebo-controlled trial con...

Purpose Prolonged postoperative ileus (POI) is a common complication after open abdominal surgery (OAS). Daikenchuto (DKT), a traditional Japanese medicine that peripherally stimulates the neurogenic pathway, is used to treat prolonged POI in Japan. To analyze whether DKT accelerates the recovery from prolonged POI after OAS, we conducted a secondary analysis of three multicenter randomized controlled trials (RCTs).

Abstract We report on a laparoscopic cholecystectomy (LC) for acute cholecystitis (AC) using the bright field/full-color fluorescence laparoscope system PINPOINT ® (Novadaq, Mississauga, ON, Canada). The patient was an 85-year-old man who was diagnosed with moderate AC. Indocyanine green (ICG) was administered just before surgery, and we used only PINPOINT ® to perform the LC. The advantage of this procedure is that it can be performed while viewing ICG fluorescence in the cystic duct. Since the...

INTRODUCTION: The PINPOINT® Endoscopic Fluorescence Imaging System (Novadaq, Mississauga, Canada) allows surgeons to visualize the bile ducts during laparoscopic cholecystectomy. Surgeons can continue operation while confirming the bile ducts' fluorescence with a bright-field/color image. However, strong fluorescence of the liver can interfere with the surgery. Here, we investigated the optimal timing of indocyanine green administration to allow fluorescent cholangiography to be performed withou...

Abstract Introduction We investigated the validity of the clinical pathway of early oral intake using a special type of food "iEat™" for patients after laparoscopic gastric cancer surgery. Methods Fifty-two patients who underwent laparoscopic surgery for gastric cancer between April 2012 and October 2013 were the participants. We provided postoperative care in accordance with a clinical pathway for laparoscopic gastrectomy that begins oral intake with "iEat™ the day after surgery. We examined co...

801Background: Postoperative intestinal hypomotility (IH) is very common after open abdominal (OAS) surgery. Although several advances have been made in medical therapy, very few recognized treatment or prevention methods are currently available. Daikenchuto (DKT), a traditional Japanese prescribed medicine, peripherally stimulates the neurogenic pathway, attempted to reduce postoperative IH in three exploratory randomized controlled trials (RCT). For further analysis of whether DKT accelerates ...
