Hemodialysis II: Procedure and Complications

790
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Diabetes: Symptoms, Diagnosis, and Complications

2.3K
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...

Liver Histology01:27

Liver Histology

4.4K
The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.
Hepatocytes perform a variety of essential functions. They secrete...

Summary
This summary is machine-generated.

Identifying risk-adjusted benchmark values (BMV) for liver surgery is crucial. These values help assess acceptable outcomes after hepatectomy, considering patient factors and reducing complication risks.

Area of Science:

  • Hepatobiliary Surgery
  • Surgical Outcomes Research
  • Medical Quality Improvement

Background:

  • Optimal short-term outcomes following liver surgery remain undefined.
  • Numerous factors can impact post-hepatectomy patient recovery and complication risk.
  • Establishing benchmark values (BMV) for liver surgery is necessary.

Purpose of the Study:

  • To identify risk-adjusted benchmark values (BMV) for liver surgery.
  • To establish standards for assessing outcomes after hepatectomy.
  • To provide a framework for evaluating surgical performance.

Main Methods:

  • Utilized the National Surgery Quality Improvement Program (NSQIP) database.
  • Developed Bayesian models to estimate risk-adjusted BMVs for overall and liver-specific complications (post-hepatectomy liver failure [PHLF], biliary leakage [BL]).
  • Validated the risk-adjusted BMVs using an international, multi-institutional database.

Main Results:

  • The NSQIP database (11,243 patients) showed complication rates of 36%, PHLF at 5%, and BL at 8%.
  • Risk-adjusted BMVs exhibited significant variability based on patient characteristics.
  • Validation using international data confirmed variability in BMVs across institutions for complications, PHLF, and BL.

Conclusions:

  • Post-hepatectomy complication risk is influenced by multiple patient factors.
  • Risk-adjusted BMVs offer a more appropriate and applicable method for assessing acceptable outcomes in liver surgery.
  • These benchmarks can aid in quality assessment and improvement initiatives.
