Background/Aims: Many Japanese institutions use electromagnetic extracorporeal shock wave lithotripsy (ESWL) systems for treating pancreatic duct stones. However, there are no reports on direct comparisons between recent electromagnetic lithotripters. This study aimed to verify whether the new electromagnetic lithotripter can improve the efficiency of pancreatic stone fragmentation, and to clarify the role of combined endoscopic treatment on the clearance of pancreatic duct stones. Methods: We retrospectively identified 208 patients with pancreatolithiasis who underwent endoscopic adjunctive treatment after pancreatic ESWL at a single Japanese center over a 17-year period. We evaluated the outcome data of this procedure performed with SLX-F2 (last 2 years; group A) and Lithostar/Lithoskop (first 15 years; group B), as well as additional endoscopic treatments for pancreatolithiasis. We also performed logistic regression analysis to detect various factors associated with the procedure. Results: For pancreatic head stones, ESWL disintegration was achieved in 93.7% of group A patients and 69.0% of group B patients (p=0.004), and adjunctive endoscopic treatment removed stones in 96.8% of group A patients and 73.0% of group B patients (p=0.003). Multivariate analysis revealed that lithotripter type (odds ratio, 6.99; 95% confidence interval, 1.56 to 31.33; p<0.01) and main pancreatic duct stricture (odds ratio, 2.87; 95% confidence interval, 1.27 to 6.45; p<0.01) were significant factors for ESWL fragmentation. Conclusions The SLX F2 showed high performance in fragmenting the pancreatic duct stones.In addition, endoscopic adjunctive treatment improved the overall success rate of the procedure. The improved ESWL lithotripter has many advantages for patients undergoing pancreatic lithotripsy treatment.

BACKGROUND/AIMS: Magnesium oxide (MgO) has been frequently used as a treatment for chronic constipation (CC) since the 1980s in Japan. The aim of this study is to evaluate its therapeutic effects of MgO in Japanese CC patients. METHODS: We conducted a randomized, double-blind placebo-controlled study. Thirty-four female patients with mild to moderate constipation were randomly assigned to either placebo (n = 17) or MgO group (n = 17) 0.5 g × 3/day for 28 days. Primary endpoint was overall improvement over the 4-week study period. Secondary endpoints were changes from baseline in spontaneous bowel movement (SBM), response rates of complete spontaneous bowel movement (CSBM), stool form, colonic transit time (CTT), abdominal symptom, and quality of life. RESULTS: One patient failed to complete the medication regimen and was omitted from analysis: data from 16 placebo and 17 MgO patients were analyzed. The primary endpoint was met by 25.0% of placebo vs 70.6% of MgO group (P = 0.015). MgO significantly improved SBM changes compared to placebo (P = 0.002). However, MgO did not significantly improved response rates of CSBM compared to placebo (P = 0.76). In addition, MgO significantly improved Bristol stool form scale changes (P < 0.001) and significantly improved CTT compared to the placebo group (P < 0.001). MgO significantly improved the Japanese version of the patient assessment of constipation quality of life (P = 0.003). CONCLUSION: Our placebo-controlled study demonstrated that MgO was effective treatment for improving defecation status and shortened CTT in Japanese CC patients with mild to moderate symptoms.

Distigmine has reversible and persistent cholinesterase (ChE) antagonism, and is used for the dysuria due to low activity bladders such as the neurogenic bladder dysfunction widely postoperatively, but fatal cases were reported by cholinergic syndrome. Therefore a dose was limited to 5mg only for adaptation of “the dysuria due to hypotonic bladder such as after surgery and the neurogenic bladder dysfunction” in March, 2010. In the current study, we examined a ministerial policy in the package insert revision using Japanese Adverse Drug Event Report database (JADER). Using a side effect report registered with JADER from January, 2004 to June, 2016, we calculated Reporting Odds Ratio (ROR) which was the index of the safe signal of the medical supplies adverse event and we compared number of reports and ROR of the cholinergic syndrome by the distigmine in approximately the measure in March, 2010 and evaluated it. The number of reports of the cholinergic syndrome by the distigmine was 138 cases before March 2010 and 65 cases after March 2010. After a measure, the number of reports decreased. The possibility that the package insert revision of the distigmine contributed to a decrease in cholinergic syndrome onset was suggested. Whereas monitoring careful sequentially needs the onset of the cholinergic syndrome in constant frequency to be found.
