Insights

Elevated INR or PTT values predict adverse outcomes and mortality after elective pancreatectomy. Coagulation profiles can identify high-risk patients needing more resources for better surgical outcomes.

Area of Science:

  • Surgical outcomes research
  • Coagulation diagnostics
  • Pancreatic surgery

Background:

  • Elective pancreatectomy carries significant postoperative risks.
  • Predictive markers for adverse events are crucial for patient management.

Purpose of the Study:

  • To investigate if elevated International Normalized Ratio (INR) or Prothrombin Time (PTT) predict 30-day adverse events after elective pancreatectomy.
  • To assess the association between prolonged bleeding times and postoperative morbidity and mortality.

Main Methods:

  • Analysis of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database (2005-2013).
  • Inclusion of 14,747 patients undergoing elective pancreatectomy.
  • Multivariate logistic regression to examine the association of elevated INR/PTT with 30-day outcomes.

Main Results:

  • A significant increase in 30-day mortality was observed in patients with elevated INR/PTT (1.8% vs. 3.3%).
  • Elevated INR/PTT correlated with increased odds of bleeding, surgical site infections, sepsis, respiratory complications, cardiac events, renal failure, reoperation, and prolonged hospital stay.
  • These associations remained significant after controlling for confounders, except for superficial surgical site infections.

Conclusions:

  • Prolonged bleeding times (elevated INR/PTT) are linked to higher mortality and adverse outcomes post-pancreas surgery.
  • Coagulation profiles, specifically INR and PTT, can serve as valuable tools for risk stratification in patients undergoing pancreatectomy.
  • Identifying high-risk patients allows for targeted resource allocation and potentially improved patient care.

Factors Affecting the Risk of Infection01:26

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...

Drug Toxicity: Risk factors01:24

Drug 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...

Coagulation01:06

Coagulation

Colloidal solids are solid particles suspended in solution. They are usually negatively charged, attracting a compact primary layer of positively charged ions, which attract more counterions to form an electrical double layer. Electrostatic repulsion between the charged double layers prevents the particles from colliding, stabilizing the colloids. These solids are often undesirable because they can contain toxins that are difficult to remove. Coagulation is a technique that helps aggregate and...

Coagulation01:09

Coagulation

The coagulation phase is a critical part of the body's process to prevent blood loss following injury to blood vessels. It involves chemical reactions that form a clot to seal the injured area. The clotting process begins shortly after injury, within 15-20 seconds for severe damage and 1-2 minutes for minor injuries.
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...

Pancreas01:19

Pancreas

The pancreas, an essential organ in the human body, is a pinkish-gray elongated structure located posterior to the stomach. It extends laterally from the duodenum towards the spleen and is firmly bound to the posterior wall of the abdominal cavity. The organ's surface has a lumpy, lobular texture that gives it a unique appearance.
The broad head of the pancreas lies within the loop formed by the duodenum, while its slender body reaches towards the spleen. The tail of the pancreas is short...

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
