The efficacy and safety of one-stage endoscopic treatment for ascending acute cholangitis caused by choledocholithiasis with severe comorbidities

Urgent one-stage endoscopic treatment for choledocholithiasis related moderate to severe acute cholangitis: A propensity score-matched analysis

BACKGROUND

During emergency endoscopic retrograde cholangiopancreatography (ERCP), the safety and feasibility of performing one-stage endoscopic treatment for patients with acute cholangitis (AC) due to choledocholithiasis are unclear.

AIM

To investigate the safety and feasibility of one-stage endoscopic treatment for moderate to severe AC.

METHODS

We enrolled all patients diagnosed with moderate to severe cholangitis due to common bile duct stones from January 2019 to July 2023. The outcomes were compared in this study between patients who underwent ERCP within 24 h and those who underwent ERCP 24 h later, employing a propensity score (PS) framework. Our primary outcomes were intensive care unit (ICU) admission rates, ICU length of stay, and duration of antibiotic use.

RESULTS

In total, we included 254 patients and categorized them into two groups based on the time elapsed between admission and intervention: The urgent group (≤ 24 h, n = 102) and the elective group (> 24 h, n = 152). Ninety-three pairs of patients with similar characteristics were selected by PS matching. The urgent ERCP group had more ICU admissions (34.4% vs 21.5%, P = 0.05), shorter ICU stays (3 d vs 9 d, P < 0.001), fewer antibiotic use (6 d vs 9 d, P < 0.001), and shorter hospital stays (9 d vs 18.5 d, P < 0.001). There were no significant differences observed in adverse events, in-hospital mortality, recurrent cholangitis occurrence, 30-d readmission rate or 30-d mortality.

CONCLUSION

Urgent one-stage ERCP provides the advantages of a shorter ICU stay, a shorter duration of antibiotic use, and a shorter hospital stay.

One-stage versus two-stage endoscopic management for acute cholangitis caused by common bile duct stones: A retrospective multicenter cohort study

BACKGROUND

One-stage endoscopic management, where papillary interventions and stone removal are simultaneously performed, has been reported to be an effective treatment for acute cholangitis caused by common bile duct stones (CBDS). However, there have been few reports comparing it with two-stage management, and there is no established strategy for the indication of one-stage management. The aim of the present study was to compare the short- and long-term outcomes between one- and two-stage management for acute cholangitis caused by CBDS.

METHODS

We retrospectively studied 577 patients who underwent one- or two-stage endoscopic management for acute cholangitis between May 2010 and December 2020. The patients were divided into one- and two-stage groups by endoscopic management. The clinical outcomes were compared between groups.

RESULTS

The technical and clinical success were similar in both groups, although the length of hospital stay was significantly shorter in the one-stage group. Although there was no difference in the early adverse event (AE) between two groups, post-ERCP pancreatitis was recognized in 3.4% and 10.0%, which was significantly higher in the two-stage group. The cumulative late AE rate was 22.6% and 14.1%, which was significantly higher in the one-stage group. In the multivariate analyses, intervention (one-stage), number of CBDS ≥2, biliary drainage, the use of ML, and gallbladder stone were identified as significant factors associated with the recurrence of CBDS.

CONCLUSION

Although one-stage endoscopic management is useful and safe with reducing hospital stays, diligent postoperative follow-up with consideration to recurrence of CBDS is essential.

Characteristics and clinical outcomes of acute cholangitis in older patients

PURPOSE

Few studies are available on older patients with acute cholangitis. In this study, we aimed to examine the clinical characteristics of older patients with acute cholangitis.

METHODS

Patients aged 65 years and over who were diagnosed with acute cholangitis between February 2019 and August 2022 were analyzed retrospectively. Patients eligible for the study were divided into two groups as those aged ≥ 80 years (octogenarian) and those aged 65-79 years (non-octogenarian). These two groups were then compared for many clinical characteristics. In addition, factors associated with in-hospital mortality were identified. Finally, a subgroup analysis was performed in patients with non-malignant etiology.

RESULTS

Of a total of 309 enrolled patients, 120 (38.8%) were in the octogenarian group and 189 (61.2%) were in the non-octogenarian group. The mean age was 77.2 ± 8.0 years and 51.8% were women. Severe disease and intensive care unit admission rates were higher in the octogenarian group (p = 0.035 and p = 0.002, respectively), but there was no significant difference in the rate of in-hospital mortality (p = 0.146). Malignant etiology (OR 2.990, 95% CI 1.131-7.904) and hypoalbuminemia (OR 0.824, 95% CI 0.751-0.903) were independent risk factors for in-hospital mortality. In the subgroup analysis of non-malignant etiology, the octogenarian group had a significantly higher in-hospital mortality rate than the non-octogenarian group (8.8% vs. 3.2%, p = 0.048).

CONCLUSIONS

Among older patients with acute cholangitis, clinicians should closely monitor those aged 80 years and over, as well as those with malignant etiology and hypoalbuminemia, due to their high risk of serious clinical events.

Urgent and emergency endoscopic retrograde cholangiopancreatography for gallstone-induced acute cholangitis and pancreatitis

Urgent or emergency endoscopic retrograde cholangiopancreatography (ERCP) is indicated for gallstone-induced acute cholangitis and pancreatitis. The technique and optimal timing of ERCP depend on the disease state, its severity, anatomy, patient background, and the institutional situation. Endoscopic transpapillary biliary drainage within 24 h is recommended for moderate to severe acute cholangitis. The clinical outcomes of biliary drainage with nasobiliary drainage tube placement and plastic stent placement are comparable, and the choice is made on a case-by-case basis considering the advantages and disadvantages of each. The addition of endoscopic sphincterotomy (EST) is basically not necessary when performing drainage alone, but single-session stone removal following EST is acceptable in mild to moderate cholangitis cases without antithrombotic therapy or coagulopathy. For gallstone pancreatitis, early ERCP/EST are recommended in cases with impacted gallstones in the papilla. In some cases of gallstone pancreatitis, a gallstone impacted in the papilla has already spontaneously passed into the duodenum, and early ERCP/EST lacks efficacy in such cases, with unfavorable findings of cholangitis or cholestasis. If it is difficult to diagnose the presence of gallstones impacted in the papilla on imaging, endoscopic ultrasonography can be useful in determining the indication for ERCP.
