RESUMEN
BACKGROUND: There have been reports that elobixibat improves bowel movements in patients with chronic constipation. However, no studies have been conducted to date to examine bowel movements after the administration of elobixibat in patients with chronic constipation in terms of the presence or absence of the gallbladder. In this study, we examined the frequency of bowel movements and stool forms in patients with gallbladders and post-cholecystectomy patients before and after the administration of elobixibat for chronic constipation. METHODS: Elobixibat 10 mg was administered to treat chronic constipation in 40 patients with gallbladders and 18 patients who underwent cholecystectomy. The frequencies of bowel movements one week before and after elobixibat administration were compared between the two groups, using the Bristol Stool Form Scale (BSFS). RESULTS: No significant difference in patient background with or without cholecystectomy was noted between the groups. In patients with gallbladders, the pre-dosing mean frequency of bowel movements was 2.389 ± 0.502 with BSFS of 2.179 ± 0.721 and the post-dosing mean frequency of bowel movements was 4.308 ± 1.151 with BSFS of 3.718 ± 1.521, indicating significant improvement in bowel movements (p < 0.001). In post-cholecystectomy patients, the pre-dosing mean frequency of bowel movements was 2.389 ± 0.502 with BSFS of 2.222 ± 0.647 and the post-dosing mean frequency of bowel movements was 4.222 ± 1.734 with BSFS of 3.333±1.237, indicating significant improvement in bowel movements (p < 0.001). No significant difference in bowel movements was noted between patients with or without the gallbladder. CONCLUSIONS: Elobixibat is useful in improving the bowel movements of patients with chronic constipation. No significant difference was noted in the improvement of bowel movements due to cholecystectomy. It was suggested that even post-cholecystectomy patients could obtain therapeutic effects similar to patients with gallbladders.
RESUMEN
INTRODUCTION: Endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic sphincterotomy (EST) are said to be useful procedures for gallstone pancreatitis. However, there have been few reports on a large number of patients to whom they were used. The clinical usefulness of ERCP and EST is herein examined retrospectively. METHODS: ERCP and EST were performed to evaluate their clinical usefulness and safety in 108 patients who had gallbladder stones from December 1985 to October 2017 and were diagnosed as having gallstone pancreatitis. Of 108 patients, 83 were mild, and 25 were severe. Following the procedures, clinical courses were observed for three years in 108 patients who underwent the treatments. RESULTS: Cholangiogram was successfully conducted in 108 patients. Bile duct stones were noted in 90 patients, and the stones were removed after EST. Of 18 patients who did not show bile duct stone in cholangiogram, 13 patients underwent EST, while five patients taking anticoagulants completed procedures only with cholangiogram. Accidental symptom was hemorrhage in three patients (2.7%; 3/108), but it was mild and conservatively resolving. During the three-year observation period, acute cholangitis was noted in three patients (2.7%; 3/108), but no relapsing pancreatitis was noted. CONCLUSIONS: It was suggested that ERCP and EST could be useful therapies for gallstone pancreatitis.
RESUMEN
BACKGROUND: Several studies have explored the long-term prognosis of patients with asymptomatic gallbladder stones. These reports were primarily conducted in facilities equipped with beds for addressing symptomatic cases. AIM: To report the long-term prognosis of patients with asymptomatic gallbladder stones in clinics without bed facilities. METHODS: We investigated the prognoses of 237 patients diagnosed with asymptomatic gallbladder stones in clinics without beds between March 2010 and October 2022. When symptoms developed, patients were transferred to hospitals where appropriate treatment was possible. We investigated the asymptomatic and survival periods during the follow-up. RESULTS: Among the 237 patients, 214 (90.3%) remained asymptomatic, with a mean asymptomatic period of 3898.9279 ± 46.871 d (50-4111 d, 10.7 years on average). Biliary complications developed in 23 patients (9.7%), with a mean survival period of 4010.0285 ± 31.2788 d (53-4112 d, 10.9 years on average). No patient died of biliary complications. CONCLUSION: The long-term prognosis of asymptomatic gallbladder stones in clinics without beds was favorable. When the condition became symptomatic, the patients were transferred to hospitals with beds that could address it; thus, no deaths related to biliary complications were reported. This finding suggests that follow-up care in clinics without beds is possible.
RESUMEN
Many molecular targeted agents, including biologics, have emerged for inflammatory bowel diseases (IBD), but their high prices have prevented their widespread use. This study aimed to reveal the changes in patient characteristics and the therapeutic strategies of IBD before and after the implementation of biologics in Japan, where the unique health insurance system allows patients with IBD and physicians to select drugs with minimum patient expenses. The analysis was performed using a prospective cohort, including IBD expert and nonexpert hospitals in Japan. In this study, patients were classified into two groups according to the year of diagnosis based on infliximab implementation as the prebiologic and biologic era groups. The characteristics of therapeutic strategies in both groups were evaluated using association analysis. This study analyzed 542 ulcerative colitis (UC) and 186 Crohn's disease (CD). The biologic era included 53.3% of patients with UC and 76.2% with CD, respectively. The age of UC (33.9 years vs. 38.8 years, P < 0.001) or CD diagnosis (24.3 years vs. 31.9 years, P < 0.001) was significantly higher in the biologic era group. The association analysis of patients with multiple drug usage histories revealed that patients in the prebiologic era group selected anti-tumor necrosis factor (TNF)-α agents, whereas those in the biologic era group preferred biologic agents with different mechanisms other than anti-TNF-α. In conclusion, this study demonstrated that both patient characteristics and treatment preferences in IBD have changed before and after biologic implementation.

To gain a better understanding of the effects of biologics, we evaluated clinical outcomes in patients with moderate to severe exacerbations of ulcerative colitis (UC). This retrospective, multicenter study retrieved the entire clinical courses of UC patients who began treatments between 2004 and 2018. All exacerbations and clinical parameters, including treatment details for exacerbations and both remission and re-exacerbation dates, were identified during the observation period. Two different endpoints, the cumulative incidence rates of surgical resection and re-exacerbation, were evaluated separately in moderate to severe exacerbation events. Among 1401 patients, 1626 exacerbation events were determined according to a partial Mayo score (remission: < 2, mild: 2-4, moderate: 5-7, and severe: > 7). During the observation period, as administration rates of biologics increased, both surgical resection and hospitalization rates decreased, for 959 moderate to severe exacerbation events. We confirmed that biologics significantly reduced the cumulative re-exacerbation rate in moderate to severe exacerbation events during the study period compared with suboptimal therapies (a 0.507-fold decreased risk according to COX regression analysis, P < 0.001). However, they had not enough impact in reducing the cumulative incidence rate of surgical resection in moderate to severe exacerbation events that were corticosteroid-refractory or dependent (a 0.878-fold decreased risk according to COX regression analysis, P = 0.606). Biologics may improve remission duration, but these agents had no significant impact in reducing the risk of surgical resection in moderate to severe active UC.

BACKGROUND: In Western countries, most patients with primary sclerosing cholangitis (PSC) have concurrent ulcerative colitis (UC). The number of patients with UC in East Asia has increased markedly over the past two decades. However, current clinical features of PSC and of PSC associated with UC (PSC-UC) have not yet been clarified in East Asia, particularly in Japan. We aimed to reveal the clinical courses and associations with UC in Japanese patients with PSC from the mutual viewpoint of PSC and UC. METHODS: We retrospectively retrieved medical records of patients with PSC (69) and UC (1242) who were diagnosed at Chiba University Hospital between June 1991 and August 2017. RESULTS: In the present cohort, 37 patients had PSC-UC; the cumulative risks of PSC in patients with UC and of UC in patients with PSC were 3.0% and 53.6%, respectively. We confirmed similar distinctive results by a Japanese nationwide survey, noting that younger patients with PSC had a notably high possibility of association with UC. From the viewpoint of the UC cohort, the occurrence of right-sided disease was significantly higher in patients with PSC-UC than in those with UC (16.2% vs. 4.2%, P = 0.003). Pancolitis was more commonly observed in PSC-UC, and proctits/left-sided colitis was less commonly found in patients with UC. The number of patients with young-onset PSC-UC may be increasing similar to an increase in patients with UC in Japan. CONCLUSIONS: In our cohort, the comorbidity rate of PSC-UC was higher than that obtained in previous reports. The incidence of PSC-UC and UC may increase in the future in East Asia, particularly in Japan.

AIM: In this study, we assessed the factors contributing to ineffective drainage in the initial transpapillary uncovered self-expandable metal stent (USEMS) placements in patients with unresectable malignant hilar biliary strictures (UMHBSs) (Bismuth type II or higher). METHODS: This was a retrospective, single-center study. A total of 97 patients with UMHBSs who underwent technically successful initial USEMS placements using endoscopic retrograde cholangiopancreatography (ERCP) were classified into the effective drainage group (n = 73) or the ineffective drainage group (n = 24). We then compared group characteristics, clinical outcomes, and drained liver volumes. Drained liver volume was measured by using computed tomography volumetry. The definition of effective biliary drainage was a 50% decrease in the serum total bilirubin level or normalization of the level within 14 days of stent placement. RESULTS: Univariate analysis showed that ineffective drainage was associated with the pre-ERCP serum total bilirubin level (P = 0.0075), pre-ERCP serum albumin level (P = 0.042), comorbid liver cirrhosis (P = 0.010), drained liver volume (P = 0.0010), and single stenting (P = 0.022). Multivariate analysis identified comorbid liver cirrhosis (adjusted odds ratio [OR], 5.79; 95% confidence interval [CI], 1.30-25.85; P = 0.022) and drained liver volume < 50% (adjusted OR, 5.50; 95% CI, 1.50-20.25; P = 0.010) as independent risk factors of ineffective drainage. CONCLUSION: Comorbid liver cirrhosis and a drained liver volume < 50% contributed significantly to ineffective drainage in the initial transpapillary USEMS placements for UMHBSs.
RESUMEN
AIM: Little is known about the factors that contribute to the occurrence of adverse events in endoscopic retrograde cholangiopancreatography (ERCP) for people aged ≥85 years and safety for the super-old. Therefore, we decided to identify these factors and to examine whether ERCP is safe in the super-old. METHODS: This was a single-center retrospective study. A total of 137 patients aged ≥85 years who underwent therapeutic ERCP at Chiba University Hospital from January 2012 to March 2017 were retrospectively reviewed. RESULTS: Four cases of Billroth II reconstruction and two cases of gastrectomy with Roux-en-Y reconstruction were excluded, and 131cases in total were examined in the present study. A total of 10 and 121 cases with and without adverse events, respectively, were present. Using univariate analysis, factors significantly contributing to the occurrence of adverse events in therapeutic ERCP were identified as aged ≥90 years (P = 0.0096), duodenal papilla cancer (P = 0.0012), gallbladder carcinoma (P = 0.023), and biliary metal stenting (P = 0.040). In multivariate analysis, only ≥90 years-of-age was a significant factor (P = 0.049). In addition, comparison between 25 cases of the super-old and 106 cases aged 85-89 years was carried out. In the super-old group, the average value of the American Society of Anesthesiologists physical status classification and Charlson's Comorbidity Index were significantly better than those in 85-89-year-olds (P = 0.0035 and P < 0.0001, respectively). CONCLUSIONS: Although the super-old group had fewer comorbid diseases, they had significantly increased adverse events compared with patients aged 85-89 years.

A 68-year-old woman was referred to our hospital for the treatment of bile duct stone, pancreatic tumor, and pancreatic cysts. First, bile duct stone was removed using endoscopic retrograde cholangiopancreatography. By abdominal contrast-enhanced computed tomography, a 12-mm diameter tumor was found in the pancreatic body. The tumor was isodense compared with the surrounding pancreatic parenchyma in the non-contrast phase and poorly enhanced in the arterial phase; it exhibited gradual enhancement from the portal vein phase to the late phase. Numerous pancreatic cysts were also observed by contrast-enhanced computed tomography. By magnetic resonance imaging, the tumor was hypointense in T1-weighted images, isointense in T2-weighted images, and hyperintense in diffusion-weighted images. By magnetic resonance cholangiopancreatography, the main pancreatic duct was not dilated, and pancreatic cysts communicated with the main pancreatic duct. The pancreatic cysts were diagnosed as branch-type intraductal papillary mucinous neoplasm. Histopathologic assessment of the specimens obtained by endoscopic ultrasound-guided fine-needle aspiration revealed the tumor as benign pancreatic granular cell tumor. The patient was followed up without surgical resection. On contrast-enhanced computed tomography at 6 months after admission, the tumor did not show any changes in diameter or characteristics.

We describe a case of autoimmune hepatitis (AIH) that may have occurred following drug-induced liver injury with camostat mesilate and/or benzbromarone in an elderly patient. The patient's liver biopsy showed chronic active hepatitis and autoimmune hepatitis. Stopping the use of these drugs did not lead to complete remission, but the use of a low dose of corticosteroids completely cured his liver dysfunction. In the present case, liver dysfunction was caused by an autoimmune mechanism. Special attention should be paid to idiopathic AIH and drug-induced AIH in elderly patients.

A 24-year-old man was admitted due to acute hepatitis with unknown etiology. After his condition and laboratory data gradually improved with conservative therapy, he was discharged 1 month later. Two months after his discharge, however, liver dysfunction reappeared. After his mother accidentally revealed that he took complementary and alternative medicine, discontinuation of the therapy caused his condition to improve. Finally, he was diagnosed with a recurrent drug-induced liver injury associated with Japanese complementary and alternative medicine. It is important to take the medical history in detail and consider complementary and alternative medicine as a cause of liver disease.
