Abstract

Insights

Subphrenic infection (SI) risk after liver resection is linked to liver parenchyma resection and cirrhosis. Adequate subphrenic drainage is crucial for preventing SI in patients with hepatic malignancy.

Area of Science:

  • Hepatobiliary Surgery
  • Surgical Infections
  • Oncology

Background:

  • Subphrenic infection (SI) is a potential complication following liver resection in patients with hepatic malignancy.
  • Identifying high-risk factors is crucial for effective prevention strategies.

Purpose of the Study:

  • To clarify the high-risk factors associated with subphrenic infection (SI) after liver resection in patients with hepatic malignancy.
  • To evaluate the impact of various surgical and patient-related factors on SI incidence.

Main Methods:

  • A cohort of 368 patients undergoing hepatectomy between January 1985 and June 2002 were analyzed.
  • Patients were assessed based on liver parenchyma resection, hepatic cirrhosis, primary liver cancer characteristics, intraoperative blood loss, and subphrenic drainage.
  • Statistical analysis, including the chi-square test, was employed to determine risk factors.

Main Results:

  • The incidence of SI was 3.53% (13 out of 368 patients).
  • High-risk factors for SI included resection of liver parenchyma and hepatic cirrhosis.
  • Intraoperative blood loss exceeding 1500 ml was a significant risk factor; primary liver cancer stage was not.
  • Adequate subphrenic and raw liver surface drainage was essential for reducing SI.

Conclusions:

  • Inadequate subphrenic drainage is a major contributor to SI in patients with hepatic malignancy undergoing hepatectomy.
  • Comprehensive preventive measures are necessary to reduce the incidence of post-hepatectomy infections.

Cholecystitis

Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...

Cirrhosis II: Pathophysiology

Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...
