ABSTRACT

BACKGROUND: Short-term treatment of acute cholangitis is sufficient for cure compared with the standard treatment duration. Whether this short-course antimicrobial therapy is effective in patients with acute cholangitis with positive blood cultures has not been fully investigated. This study assessed whether patients with acute cholangitis could achieve successful outcomes with a three-day or shorter antimicrobial treatment period, even with a positive blood culture. METHODS: This single-center retrospective study involved patients with acute cholangitis, defined according to the Tokyo Guidelines 2018 for any cause, who underwent successful biliary drainage and completed a seven-day or shorter antimicrobial treatment. Patients were categorized into six groups based on the duration of antibiotic use (short or standard) after endoscopic retrograde cholangiopancreatography and blood culture findings (positive, negative, or no collection). The primary outcome was the clinical cure rate, defined as no initial presenting symptoms by day 14 after biliary drainage and no recurrence or death by day 30. Secondary outcomes included a three-month recurrence rate and length of hospital stay. RESULTS: In total, 389 cases were selected, and 27 patients (6.9%) undergoing short-course therapy tested positive for blood culture. The clinical cure rate (n=25, 92.6%) in this group was comparable to that in the other groups. For the three-month recurrence rate (n=1, 3.7%) and median hospital stay (six days), this group's outcomes were either better or similar to those of the other groups. CONCLUSIONS: For cases of successful drainage in acute cholangitis, even with positive blood cultures, short-term antibiotic therapy may be appropriate.

ABSTRACT

Background and Aim: The appropriate duration of antimicrobial therapy for acute cholangitis (AC) arising from multiple hilar biliary obstructions as opposed to simple obstruction in the extrahepatic bile duct has not been established. This study assessed the efficacy of the duration of antimicrobial treatments in the Tokyo Guidelines 2018 for AC based on the cause and site of obstruction. Methods: This single-center retrospective study involved patients with AC who underwent successful biliary drainage and completed a 7-day or shorter antimicrobial treatment. Patients were categorized into three groups: Group 1, bile duct stone or benign obstruction; Group 2, simple biliary obstruction due to malignancy; and Group 3, multiple hilar biliary obstruction due to malignancy. The primary outcome was clinical cure rate, and the secondary outcomes were 3-month recurrence rate and length of hospital stay. Results: A total of 373 patients were selected. Patients in Group 3 were younger or had Charlson Comorbidity Index ≥4, and had fewer positive blood cultures. In Group 3, the clinical cure rate (87.1%) and 3-month recurrence rate (32.3%) were less favorable than those in the other groups. In Group 1, the clinical cure rate was significantly higher (98.1%, P = 0.02) with a much lower 3-month recurrence rate of only 3.4% (P < 0.001) than that in the other groups. The median hospital stay for all groups was 7 days. Conclusion: This study suggests that the outcomes in Group 3 may be worse than those in Groups 1 or 2, regardless of the duration of the antibiotic treatment.

ABSTRACT

Video 1Selective biliary cannulation was difficult, and the catheter tended to be cannulated into the pancreatic duct. We applied a double-wire technique to achieve biliary cannulation. Finally, selective biliary cannulation was achieved. Cholangiography revealed a small stone of approximately 5 mm in the common bile duct (red arrow). Subsequently, endoscopic papillary balloon dilation (EPBD) was performed using a new EPBD catheter with a diameter of 8 mm. This new EPBD catheter was inserted. We inflated this EPBD catheter slightly while observing both endoscopy and fluoroscopy monitors to confirm its dilation process. EPBD was easily and effectively performed without slipping in or out of the papilla. The orifice of the papilla was dilated. Stone extraction was completely achieved.

ABSTRACT

OBJECTIVES: Texture and color enhancement imaging (TXI) reportedly improves the identification of the papilla of Vater for selective biliary cannulation compared with white light imaging (WLI). This multicenter study evaluated the efficacy of short-type single-balloon enteroscopy (SBE)-assisted biliary cannulation using a new-generation image-enhanced endoscopy processing system equipped with TXI in patients who underwent Roux-en-Y gastrectomy. METHODS: Patients with Roux-en-Y gastrectomy with a native papilla, and underwent short SBE-assisted biliary cannulation during endoscopic retrograde cholangiopancreatography-related procedures between January 2019 and April 2023 were retrospectively reviewed. Outcomes of biliary cannulation using TXI and WLI were compared. The primary outcome was time to successful biliary cannulation. RESULTS: Thirty-three patients underwent biliary cannulation with TXI and 98 underwent WLI. The biliary cannulation success rates and median time to successful biliary cannulation with TXI and WLI were 93.9% (95% confidence interval [CI] 79.8-99.3%) and 83.7% (95% CI 74.8-90.4%), respectively (P = 0.14), and 10 min (interquartile range [IQR] 2.5-23.5) and 18 min (IQR 9.75-24), respectively (P = 0.04). Biliary cannulation with TXI required a shorter cannulation time than that required with WLI. Adverse event rates with TXI and WLI did not differ significantly (P = 0.58). Multivariate linear regression analysis showed that the use of TXI and short length of oral protrusion were associated with a shorter successful biliary cannulation time. CONCLUSION: Short SBE-assisted biliary cannulation was effective and safe on TXI in patients who underwent Roux-en-Y gastrectomy, and achieved shorter successful biliary cannulation time.

ABSTRACT

Background and study aims Although the number of resistant bacteria tends to increase with prolonged antimicrobial therapy, no studies have examined the relationship between the duration of antimicrobial therapy and increase in the number of resistant bacteria in acute cholangitis. We hypothesized that the short-term administration of antimicrobial agents in acute cholangitis would suppress bacterial resistance. Patients and methods This was a single-center, retrospective, observational study of patients with acute cholangitis admitted between January 2018 and June 2020 who met the following criteria: successful biliary drainage, positive blood or bile cultures, bacteria identified from cultures sensitive to antimicrobials, and subsequent cholangitis recurrence by January 2022. The patients were divided into two groups: those whose causative organisms at the time of recurrence became resistant to the antimicrobial agents used at the time of initial admission (resistant group) and those who remained susceptible (susceptible group). Multivariate analysis was used to examine risk factors associated with the development of resistant pathogens. Multivariate analysis investigated antibiotics used with the length of 3 days or shorter after endoscopic retrograde cholangiopancreatography (ERCP) and previously reported risk factors for the development of bacterial resistance. Results In total, 89 eligible patients were included in this study. There were no significant differences in patient background or ERCP findings between the groups. The use of antibiotics, completed within 3 days after ERCP, was associated with a lower risk of developing bacterial resistance (odds ratio, 0.17; 95% confidence interval, 0.04-0.65; P =0.01). Conclusions In acute cholangitis, the administration of antimicrobials within 3 days of ERCP may suppress the development of resistant bacteria.

ABSTRACT

The role of computed tomography (CT) in the initial diagnosis of pancreatic cancer (PC) is well-known. CT reports made by radiologists are important as not all patients with PC are examined by specialists; however, some cases are not identified based on CT reports. Diagnosis via imaging of PC is sometimes difficult, and the diagnostic rate of PC and other pancreatic diseases can vary across radiologists. This study aimed to examine the diagnostic rate of PC in initial CT reports and the details of cases with diagnostic difficulties. This single-centered, retrospective study collected clinical data of 198 patients with histologically diagnosed PC between January 2018 and April 2022. Out of these contrast-enhanced CT was performed in 192 cases. PC was not reported as the main diagnosis in 18 patients (9.4%; 11 men and 7 women). Among these 18 cases, intrapancreatic mass lesions were detected in 3 (1.6%), indirect findings such as bile/pancreatic duct stenosis or dilation were detected in 5 (2.6%), and no PC-related findings were found in 10 (5.2%). The specialists suspected PC in 15 of these 18 cases based on initial CT reports. 17 cases were confirmed by endoscopic ultrasound-fine needle aspiration and one by biopsy after upper gastrointestinal endoscopy. To improve accuracy of its diagnosis, it is important that specialists provide feedback to diagnostic radiologists regarding the findings they did not report. Endoscopic ultrasound-fine needle aspiration should be performed by specialists when there is clinical information which indicates pancreatic disease of any kind.

ABSTRACT

BACKGROUND/AIMS: Endoscopic ultrasound-guided tissue acquisition (EUS-TA) using Franseen needles is reportedly useful for its high diagnostic yield. This study compared the diagnostic yield and puncturing ability of EUS-TA using 22-gauge cobalt-chromium (CO-Cr) needles with those of stainless-steel Franseen needles in patients with solid pancreatic lesions. METHODS: Outcomes were compared between the 22-gauge Co-Cr Franseen needle (December 2019 to November 2020; group C) and stainless-steel needle (November 2020 to May 2022; group S). RESULTS: A total of 155 patients (group C, 75; group S, 80) were eligible. The diagnostic accuracy was 92.0% in group C and 96.3% in group S with no significant intergroup differences (p=0.32). The rate of change in the operator (from training fellows to experts) was 20.0% (15/75) in group C and 7.5% (6/80) in group S. Stainless-steel Franseen needles showed less inter-operator difference than Co-Cr needles (p=0.03). CONCLUSION: Both Co-Cr and stainless-steel Franseen needles showed high diagnostic ability. Stainless-steel Franseen needles are soft and flexible; therefore, the range of puncture angles can be widely adjusted, making them suitable for training fellows to complete the procedure.

ABSTRACT

Splenic diseases may be caused by infections and can be either malignant, such as lymphoma and lung cancer, or benign, such as hemangioma. In some cases, diagnostic uncertainty of imaging persists, and image-guided splenic needle biopsy is a useful diagnostic tool to avoid the disadvantages of incorrect diagnosis, including performing unnecessary splenectomy or not giving the necessary treatment. Splenic biopsies can be divided into ultrasound-guided, computed tomography (CT)-guided fine-needle aspiration, or core needle biopsy (CNB). However, few studies have focused exclusively on complications associated with CT-guided CNB of the spleen. Therefore, we assessed bleeding, the most common complication of CT-guided CNB of the spleen, and evaluated factors associated with the bleeding. Using the biopsy database maintained at the institution, all patients who underwent CT-guided CNB of the spleen between May 2012 and September 2022 were identified retrospectively. The 18 identified patients were divided into post-biopsy bleeding and non-bleeding groups for analysis. In total, 17 patients (94.4%) could be diagnosed accurately with CT-guided CNB. Bleeding complications occurred in 7 cases of CT-guided CNB; of these, 2 patients with Common Terminology Criteria for Adverse Events grade 4 disease required transcatheter arterial embolization. The bleeding group was characterized by diffuse spleen tumors in all cases, with significantly more diffuse spleen tumors than the non-bleeding group. CT-guided CNB is a useful option for neoplastic lesions of the spleen that are difficult to diagnose using imaging alone. However, consideration should be given to post-biopsy bleeding in patients with diffuse splenic tumors.

ABSTRACT

BACKGROUND: Myalgic encephalomyelitis/chronic fatigue syndrome/systemic exertion intolerance disease (ME/CFS/SEID) is a condition diagnosed primarily based on clinical symptoms, including prolonged fatigue and post-exertional malaise; however, there is no specific test for the disease. Additionally, diagnosis can be challenging since healthcare professionals may lack sufficient knowledge about the disease. Prior studies have shown that patients with ME/CFS/SEID have low serum acylcarnitine levels, which may serve as a surrogate test for patients suspected of having this disease. This systematic review and meta-analysis aimed to investigate the differences in serum acylcarnitine levels between patients with ME/CFS/SEID and healthy controls. METHODS: This systematic review was conducted using PubMed and Ichushi-Web databases. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, we included all studies from the databases' inception until February 17, 2023, that evaluated blood tests in both patients with ME/CFS/SEID and healthy control groups. The primary endpoint was the difference in serum acylcarnitine levels between the two groups. RESULTS: The electronic search identified 276 studies. Among them, seven met the eligibility criteria. The serum acylcarnitine levels were analyzed in 403 patients with ME/CFS/SEID. The patient group had significantly lower serum acylcarnitine levels when compared with the control group, and the statistical heterogeneity was high. CONCLUSION: The patient group had significantly lower serum acylcarnitine levels when compared with the control group. In the future, the measurement of serum acylcarnitine levels, in addition to clinical symptoms, may prove to be a valuable diagnostic tool for this condition.

ABSTRACT

BACKGROUND AND AIMS: Endoscopic papillary balloon dilation (EPBD), a low-risk procedure for bleeding, has been suggested as an alternative to endoscopic sphincterotomy for papillary dilatation in patients undergoing endoscopic stone removal who are at a higher risk of bleeding. Several guidelines recommend that combination of two antiplatelet agents should be reduced to single antiplatelet therapy when endoscopic sphincterotomy is performed. However, there is no evidence that EPBD affects the risk of bleeding in patients receiving a combination of two antiplatelet agents; thus, we aimed to explore this problem. METHODS: We included 31 patients who underwent EPBD for common bile duct stones at our hospital from May 2014 to August 2022 and received either a combination of two antiplatelet agents or single antiplatelet therapy prior to the procedure. The group receiving a combination of two antiplatelet agents included patients who underwent EPBT without antiplatelet therapy withdrawal or with a shorter withdrawal period than those recommended by the guidelines. RESULTS: In the group that received a combination of two antiplatelet agents, one of the two antiplatelet agents used was thienopyridine. No bleeding was observed after EPBD in this study. We did not find any significant between-group differences in hemoglobin levels and rate of post-endoscopic retrograde cholangiopancreatography pancreatitis. CONCLUSIONS: In patients treated with a combination of two antiplatelet agents, EPBD could be safely performed without bleeding. Therefore, future prospective studies are warranted.
