Summary
Percutaneous postoperative choledochoscopy effectively removes residual stones after hepatolithiasis treatment. This procedure demonstrated a high stone clearance rate with manageable complications, confirming its safety and efficacy.
Area of Science:
- Gastroenterology and Hepatobiliary Surgery
- Minimally Invasive Procedures
Background:
- Hepatolithiasis treatment has advanced with improved choledochoscopy technology.
- Residual stones post-treatment pose a clinical challenge.
Purpose of the Study:
- To analyze the efficacy and complications of percutaneous postoperative choledochoscopy (PPOC) for residual hepatolithiasis stones.
- Evaluate PPOC as a treatment option for remnant biliary calculi.
Main Methods:
- Retrospective analysis of 826 patients undergoing PPOC for residual stones.
- Key outcome measures: stone removal rate and postoperative complications.
Main Results:
- A high residual stone clearance rate of 97% was achieved.
- The average procedure duration was 30 minutes.
- Complications included basket incarceration, T-tube dislodgement, bleeding, bile leaks, and infection.
Conclusions:
- Percutaneous postoperative choledochoscopy is a safe and effective method for managing residual stones after hepatolithiasis treatment.
- PPOC offers a high success rate in stone clearance.

Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...

02:33Lattice Centering and Coordination Number
11.5K
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.

6.6K
The center of gravity (COG) of an object is the point where the object's total weight is considered to be concentrated. Knowing the location of the center of gravity is useful when predicting the behavior of a moving object or designing static structures. In a uniform gravitational field, the center of gravity is similar to the center of mass (COM); yet, these two points can be positioned differently. For example, the Moon's center of mass lies very close to its geometric center, but...

2.1K
The center of gravity is the point at which an object's weight appears to be concentrated and can be used to balance the object perfectly. This point is essential in mechanics as it provides information regarding a body's stability and moments of inertia. The center of gravity does not always have to fall within the shape or boundaries of the body; it may also lie outside the body in certain cases.
To determine its location, the principle of moments can be utilized by dividing the object into...

The center of mass is the point at which the total mass of an object can be said to be concentrated. It is a fundamental principle in mechanics and physics that applies to all objects regardless of their shape or size. The center of gravity is the point at which an object’s weight appears to be concentrated and can be used to balance the object perfectly.
The knowledge of the center of mass can also help us to describe and predict the motion of objects. For example, when a ball is thrown...

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...
