Summary
Older age, prior endoscopic retrograde cholangiopancreatography (ERCP) history, and hilar obstruction are key risk factors for post-ERCP cholangitis. Understanding these factors aids in preventing this common complication.
Area of Science:
- Gastroenterology
- Hepatology
- Endoscopic Procedures
Background:
- Endoscopic retrograde cholangiopancreatography (ERCP) is a common procedure with potential complications.
- Post-ERCP cholangitis is a significant concern requiring investigation into its risk factors and prevention strategies.
Purpose of the Study:
- To identify patient-related and procedure-related risk factors for post-ERCP cholangitis.
- To determine the independent risk factors and potential protective factors for this complication.
Main Methods:
- Retrospective analysis of 4234 ERCP cases performed between January 2008 and December 2013.
- Statistical analysis, including univariate and multivariate analyses, to identify risk factors.
- Analysis of the temporal occurrence of post-ERCP cholangitis.
Main Results:
- ERCP success rate was 96.8%, with an overall complication rate of 9.4%.
- Post-ERCP cholangitis occurred in 2.4% of cases, with the highest incidence between 24-48 hours post-procedure.
- Independent risk factors identified were older age, previous ERCP history, and hilar obstruction. Endoscopic stone extraction showed a protective effect.
Conclusions:
- Older age, previous ERCP history, and hilar obstruction are independently associated with post-ERCP cholangitis.
- These findings highlight the importance of considering these factors in managing patients undergoing ERCP to mitigate risks.

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

01:17Other Factors Affecting Respiration Centers
1.6K
Breathing is primarily an involuntary activity regulated by the brainstem respiratory centers. However, it can also be consciously controlled, allowing us to hold our breath or take deeper breaths when needed. This voluntary control is facilitated by the cerebral motor cortex, which bypasses the medullary centers to stimulate the respiratory muscles directly.
However, the ability to hold one's breath voluntarily is not limitless. When the CO2 concentration in the blood reaches a critical...

01:24Drug Toxicity: Risk factors

Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...

01:31Chemical Factors Affecting Respiration Centers
2.4K
Chemical factors such as changing CO2, O2, and H+ levels in arterial blood play a critical role in influencing respiration depth and rates. These variations are detected by chemoreceptors—specialized sensors located in two primary body areas. Central chemoreceptors are found throughout the brain stem, including the ventrolateral medulla, while peripheral chemoreceptors are located in the aortic arch and carotid arteries.

3.8K
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

12.6K
The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.
