Objective:

Aim: To evaluate the risk factors for PEP in SOD types I and II.

Patients And Methods:

Materials and Methods: We retrospectively analyzed 107 cases of SOD type I, II with undergoing ERCP. Potential risk factors for PEP were investigated: age<60 years, gender, history of cholecystectomy, history of EST, normal serum bilirubin level, common bile duct≤10 mm, gallbladder stones, periamullary diverticulum, papilla size ≥15 mm, initial ERCP success, selective biliary cannulation, pancreatic cannulation/injection, Precut and EST. Factors both significant (p<0.05) for univariate and multivariate analyses were identified as independent risk factor for PEP.

Results:

Results: The overall PEP rate was 14% (15/107). Univariate analysis (ꭓ2) showed that only bilirubin level was significantly (p<0.05) associated with PEP. Multivariate analysis by multinomial regression showed that two factors were associated with PEP - normal bilirubin level (OR 9.574, 95% CI 1.869-49.034, p=0.007) and Precut (OR 0.116, 95% CI 0.014-0.979, p=0.048).

Conclusion:

Conclusions: Normal serum bilirubin level is an independent risk factor for PEP in patients with Type I and Type II of SOD. In cases of suspected or confirmed Type I, II of SOD with normal bilirubin level, ERCP with EST should be avoided and replaced by medical treatment or, if ERCP had been chosen, advanced PEP prophylactic measures should be done.

Factors Affecting the Risk of Infection

Factors Affecting the Risk of Infection

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...

Endoscopic Procedures V: ERCP

Endoscopic Procedures V: ERCP

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.

Relative Risk

Relative Risk

Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

Factors Affecting Renal Clearance: Drug's Physicochemical Properties and Plasma Levels

Factors Affecting Renal Clearance: Drug's Physicochemical Properties and Plasma Levels

Renal clearance of a drug is influenced by various factors, including its physicochemical properties and plasma levels. These factors play a significant role in determining how efficiently the kidneys eliminate a drug.
One important factor is the drug's molecular size. The kidneys readily excrete smaller molecules below 300 Daltons (Da). On the other hand, molecules weighing between 300 and 500 Da are excreted through both urine and bile. Larger molecules above 500 Da tend to be excreted...

Normal Stress

Normal Stress

Normal stress is a type of stress that occurs when forces act perpendicular, or normal, to a material's cross-sectional area. This stress often arises in structures when subjected to axial loading, which is the application of force along the axis of an object. A practical example of this can be found in bridge truss members.
When a rod is under axial loading, the internal forces and corresponding stress are normal to the plane of the section, so it is termed normal stress. It's important to...

Normal Distribution

Normal Distribution

The normal, a continuous distribution, is the most important of all the distributions. Its graph is a bell-shaped symmetrical curve, which is observed in almost all disciplines. Some of these include psychology, business, economics, the sciences, nursing, and, of course, mathematics. Some instructors may use the normal distribution to help determine students’ grades. Most IQ scores are normally distributed. Often real-estate prices fit a normal distribution. The normal distribution is...
