Introduction. The principal therapy for gallstones was open cholecystectomy. Recently, however, with remarkable advances in laparoscopic surgery on the biliary tract in particular, laparoscopic cholecystectomy has become preferred treatment for symptomatic cholelithiasis. To assess our experience in surgical treatment for gallstones and determine the best method to reduce postoperative discomfort, cases of cholecystectomy performed in our institution were reviewed.
Patients.-During the past 14 years, 524 patients were treated for cholelithiasis (cholecystolithiasisin 412, choledocho-cholecystolithiasis in 75, choledocholithiasis in 36, intrahepatic stones in 1). The ratio of men to women was 1: 1.7 and the average age was 61 years. Results.-Only cholecystectomy was performed on 86% of the patients with cholecystolithiasis and 91% had accompaning open surgery with laparoscopic cholecystectomy in latest years. Open cholecystectomy by inserting a T tube was done on 61% of choledochocholecystolithiasis cases. In some cases papilloplasty and/or choledochoduodeno or choledochojejunostomy followed. Almost all patients with choledocholithiasis had open cholecystectomy with T-tube insertion and additional procedures to remove stones in thebiliary tract in earlier years. In these years, no more addidional procedures except for choledochotomy with T-tube insertion had been performed in any cholelithiasis cases.
Conclusions.-Laparoscopic cholencystetomy is a safe and effective procedure and should be preferred for symptomatic cholelithiasis except for cases with acute cholecystitis, common bile duct stones, gallbladder cancer and other severe complications.

Between 1970 and October, 1992, 120 cases of abdominal aortic aneurysms (AAA) were treated for surgical repair. Thirteen of these cases (11%) were performed with simultaneous repair for coexistent visceral vascular diseases and other intestinal organ diseases. Another 9 patients (7.5%) were treated with coronary revascularization for combined ischemic heart disease. Six of these cases received both operations during the same hospital stay. Our surgical strategy for coexistent AAA and ischemic coronary artery disease is basically a staged operation. Coronary revascularization should precede AAA repair. Operative mortality was 1.1 percent for elective AAA repair. Long-term survival was 78% for elective surgery with a mean follow-up of 51 months, and 52% for emergency surgery with a mean follow-up of 46 months. Major risks for late death were malignant neoplasms and ischemic coronary artery disease. Survival rate of the 9 patients with successful concomitant coronary revascularization and AAA repair was 89% after 51 months of mean follow-up. We conclude that re-evaluation for coexistent ischemic heart disease is the most important point for management before and after AAA repair.

Among the 203 cases of aortic valvular surgery, we experienced 8 cases of acute coronary insufficiency during the early postsurgical period. Five cases suffered from right coronary insufficiency. The other 2 cases had left coronary failure, and the remaining case had both. The main symptom of right coronary failure was right ventricular dysfunction, resulting in inability to wean from cardiopulmonary bypass in 3 cases, and left ventricular dysfunction due to inferior myocardial infarction in 2 cases. On the other hand, the main symptom of left coronary insufficiency was acute left ventricular pump failure with a broad anteroseptal infarction, and cardiac arrest occurred in the other 2. All patients receiving an emergency coronary artery bypass graft survived. Two cases expired due to thromboembolism in the interposed graft to the left coronary ostium in Cabrol's or Piehler's procedures. In the 6 survivors we could not detect any recent coronary lesions by postsurgical coronary cineangiography. We suggest that the pathophysiology of this phenomenon was coronary artery spasm and a lack of coronary reserve capacity in severe left ventricular hypertrophy of aortic valvular disease combined with diastolic dysfunction. Prompt coronary artery bypass grafting and a careful myocardial protection using retrograde cardioplegic solutions might save patients in this critical condition and an appropriate decision on the surgical indications for aortic valvular surgery is necessary before the occurrence of left ventricular diastolic dysfunction and demand ischemia.

Academic dissertations on Kampo medicine have a certain peculiarity about them, when they are drawn up by the rules of western medical writing. Compared to western medicine, oriental medicine tends to employ more subjective terms, because of its many humanistic elements.Study objectives, methods, results and discussions however, need to be stated objectively in a way that makes a paper easy to understand for both referees and readers. Although it would be ideal to use designated terms when making objective statements, there are in fact many terms that have multiple meanings, which need to be clarified in a paper. And when presenting new evidence, one must declare how far any problems have been resolved, as clearly as possible.We have explained the recent changes to our regulations for contributors, regarding Kampo formulae naming conventions, abstract word counts, and contributions by mail. Here we discuss how our editing work proceeds, and our thoughts on how papers are re-reviewed or rejected.

BACKGROUND/AIMS: The interaction between nonsteroidal anti-inflammatory drugs (NSAIDs) and Helicobacter pylori remains controversial. We retrospectively investigated whether H. pylori infection exacerbates severe gastric mucosal injury among chronic NSAID users. METHODS: From January 2010 to December 2013, a total of 245 long-term NSAID (including low-dose aspirin) users who had undergone an esophagogastroduodenoscopy and had been evaluated for H. pylori infection were enrolled at Okayama University Hospital and Tsuyama Chuo Hospital. The degree of gastric mucosal injury was assessed according to the modified Lanza score (MLS). Severe gastric mucosal injury was defined as an MLS > or =4. Univariate and multivariate logistic regression analyses were performed. RESULTS: In the univariate analysis, age > or =75 years (odds ratio [OR], 2.4; 95% confidence interval [CI], 1.3 to 4.2), H. pylori-positivity (OR, 2.0; 95% CI, 1.2 to 3.5), and the concomitant use of proton pump inhibitors (PPIs) (OR, 0.48; 95% CI, 0.26 to 0.86) were significantly associated with severe gastric mucosal injury. The multivariate analysis was adjusted by age and sex and demonstrated that H. pylori-positivity (OR, 1.8; 95% CI, 1.0 to 3.3) and the concomitant use of PPIs (OR, 0.53; 95% CI, 0.28 to 0.99) significantly contributed to severe gastric mucosal injury. CONCLUSIONS: H. pylori infection exacerbates severe gastric mucosal injury among chronic NSAID users.

Tenmin NAMIKAWA (並河天民) thought the Shanghanlun (傷寒論) was an important text. He also taught his pupils the importance of prescribing Zhongjing ZHANG's (張仲景) medicines. Ryokyu ARIMA (有馬凉及) was a physician-teacher, who prescribed Chengqitang (承気湯) for the emperor without conferring with other doctors. His chengqitang formulary was derived from medical texts by Zhongjing ZHANG. Kyugo GODA (合田求吾) on the other hand, was a pupil of Ikkannsai MATSUBARA (松原一閑斎), who wrote in the Idokikigaki (医道聞書) : theKoho (古方) school started by Ryokyu ARIMA. He was a hero who was punished by the Goseiin (後西院) emperor. He taught Koho to Tenmin. This therefore reveals that Ryokyu ARIMA was a teacher who taught the importance of the Shanghanlun.

The aim of this study was to investigate the longitudinal effect of mobility and daily activity, in the form of exercise and everyday activities, on the bones of 102 elderly female nursing home residents who had physical disabilities as well as marked postmenopausal bone loss, using calcaneal ultrasound apparatus for bone evaluation.Of the 102 subjects initially measured, 74 (mean age, 83.5±6.55 years; range, 64-99 years) could be measured again approximately one year later. The osteo sono-assessment index (OSI) in this study was determined using an ultrasound bone evaluation device. This device measures the speed of sound (SOS) and transmission index (TI) as ultrasound passes through the calcaneus. The OSI is calculated by computer analysis (OSI=TI×SOS(2)). For mobility, the OSI decreased significantly by an average of 1.8% after 11.8 months in all of the residents who were using a wheelchair (n=41, p<0.01). In contrast, the OSI rose significantly by a mean of 1.9% in the ambulatory group (n=33, p<0.01).The OSI increased significantly in residents who exercised every day, were out of bed for at least seven hours per day, and walked on a regular basis, suggesting that exercise, mainly in the form of walking, may increase the calcaneal OSI.

BACKGROUND: We hypothesized that ketamine, when administered as the anesthetic induction agent, may prevent cardiovascular depression during high-dose remifentanil administration, unlike propofol. To test our hypothesis, we retrospectively compared the hemodynamic effects of ketamine, during high-dose remifentanil administration, with those of propofol. METHODS: Thirty-eight patients who underwent oral surgery at the Nagasaki University Hospital between April 2014 and June 2015 were included in this study. Anesthesia was induced by the following procedure: First, high-dose remifentanil (0.3-0.5 µg/kg/min) was administered 2-3 min before anesthesia induction; next, the anesthetic induction agent, either propofol (Group P) or ketamine (Group K), was administered. Mean arterial pressure (MAP) and the heart rate were recorded by the automated anesthesia recording system at four time points: immediately before the administration of high-dose remifentanil (T1); immediately before the administration of propofol or ketamine (T2); 2.5 min (T3), and 5 min (T4) after the administration of the anesthetic induction agent. RESULTS: In Group P, the MAP at T3 (75.7 ± 15.5 mmHg, P = 0.0015) and T4 (68.3 ± 12.5 mmHg, P < 0.001) were significantly lower than those at T1 (94.0 ± 12.4 mmHg). However, the MAP values in the K group were very similar (P = 0.133) at all time points. The heart rates in both Groups P (P = 0.254) and K (P = 0.859) remained unchanged over time. CONCLUSIONS: We showed that ketamine, when administered as the anesthetic induction agent during high-dose remifentanil administration, prevents cardiovascular depression.

Background/Aims: Endoscopic submucosal dissection (ESD) for diverticulum-associated colorectal lesions is generally contraindicated because of the high risk of perforation. Several studies on patients with such lesions treated with ESD have been reported recently. However, the feasibility and safety of ESD for lesions in proximity to a colonic diverticulum (D-ESD) have not been fully clarified. The aim of this study was to evaluate the feasibility and safety of D-ESD. Methods: D-ESD was defined as ESD for lesions within approximately 3 mm of a diverticulum. Twenty-six consecutive patients who underwent D-ESD were included. Two strategic approaches were used depending on whether submucosal dissection of the diverticulum-related part was required (strategy B) or not (strategy A). Treatment outcomes and adverse events associated with each strategy were analyzed. Results: The en bloc resection rate was 96.2%. The rates of R0 and curative resection in strategies A and B were 80.8%, 73.1%, 84.6%, and 70.6%, respectively. Two cases of intraoperative perforation and one case of delayed perforation occurred. The delayed perforation case required emergency surgery, but the other cases were managed conservatively. Conclusions D-ESD may be a feasible treatment option. However, it should be performed in a high-volume center by expert hands because it requires highly skilled endoscopic techniques.
