Secondary peritonitis

Secondary peritonitis is an acute inflammation of the abdominal cavity caused by an infection that occurs as a result of the penetration of microbes from damaged or inflamed abdominal organs. This condition requires immediate medical intervention, as it can lead to severe complications and even death of the patient. Secondary peritonitis often develops as a result of diseases such as acute appendicitis, perforation of hollow organs, irradiation of infections from adjacent anatomical structures, as well as as a result of injuries and surgical interventions. Timely diagnosis and adequate treatment play a critical role in improving the prognosis and reducing the risk of complications.

History of the disease and interesting historical facts

Secondary peritonitis has been mentioned in the history of medicine for centuries. One of the first documented cases of peritonitis was described by Hippocrates in the 5th century BC, describing symptoms such as abdominal pain and high fever. The prototypes of modern surgical interventions began to develop only in the 16th and 17th centuries, when surgeons began to recognize the need for an accurate diagnosis and rapid removal of the source of infection. Advances in understanding the causes and pathophysiology of peritonitis occurred largely due to the work of Joseph Lister in the 19th century, who introduced the principles of antisepsis and asepsis, which greatly increased the success of surgery and reduced surgical complications such as peritonitis. It is also worth noting that during the First and Second World Wars, there was an increase in the disease in combat situations, which contributed to the development of new methods of rapid diagnosis and treatment.

Epidemiology

Secondary peritonitis is a serious medical problem with high morbidity and mortality. Statistics show that its incidence varies depending on the region and availability of medical care, but it is estimated that in global practice it occurs in 1-7% patients hospitalized for acute animal pain. According to some studies, among all cases of acute animal diseases, peritonitis can account for 10-30%. Mortality in secondary peritonitis varies from 10 to 30% and higher, depending on the severity of the patient's condition at the time of treatment, the presence of concomitant diseases and the adequacy of the medical care provided.

Genetic predisposition to this disease

At present, studies show that genetic predisposition to secondary peritonitis is poorly understood. However, there is evidence that some genetic variations may influence the body's immune response, which may predispose to the development of infectious complications, including peritonitis. For example, genetic mutations in the immune response system, such as polymorphisms in the interleukin (IL-10, IL-6) and tumor necrosis factor (TNF) genes, may influence susceptibility to infections. However, further studies are needed to better understand the genetic factors that contribute to the development of secondary peritonitis.

Risk factors for the development of this disease

Risk factors for secondary peritonitis can be varied and include both physical and chemical aspects:

• The presence of acute diseases of the abdominal organs, such as appendicitis, cholecystitis and ulcer perforation.
• Surgical interventions on abdominal organs that may lead to suppuration or infection.
• Abdominal injuries resulting in rupture of hollow organs.
• Immunodeficiency states, including HIV, immunosuppressant therapy.
• Diseases such as diabetes that may affect the course of the infection.
• Incorrect use of antibiotics and a sharp decrease in their effectiveness due to bacterial resistance.

Diagnosis of this disease

The main task in diagnosing secondary peritonitis is to quickly determine the source of infection. The main symptoms of the disease are:

• Acute abdominal pain that may be diffuse or localized.
• An increase in body temperature, often accompanied by chills.
• Nausea and vomiting.
• Symptoms of peritoneal irritation, such as the patient's "sparing posture".

Laboratory studies usually include a complete blood count, which shows leukocytosis and an increase in C-reactive protein. It is also important to conduct a urine analysis and bacterial cultures to determine pathogenic flora. Radiological examinations, such as ultrasound and CT of the abdomen, help to visualize changes in the organs and the presence of free fluid. Differential diagnosis requires the exclusion of other conditions, such as pancreatitis, intestinal infectious diseases and genitourinary infections.

Treatment

Treatment of secondary peritonitis requires a comprehensive approach and includes the following components:

• General treatment: the patient must be hospitalized in the surgical department.
• Pharmacological treatment: administration of broad-spectrum antibiotics such as cephalosporins, as well as analgesics to control pain.
• Surgical treatment: Surgery is often required to remove the source of infection, such as drainage of abscesses or resection of affected areas.
• Other treatments: Probiotics and agents to correct electrolyte imbalances may be helpful in restoring normal gastrointestinal function.

List of medications used to treat this disease

• Cefotaxime is an antibiotic effective against gram-positive and gram-negative microorganisms.
• Meropenem is a beta-lactam antibiotic with a broad antimicrobial spectrum.
• Metronidazole is an antimicrobial drug effective against anaerobic bacteria.
• Paracetamol - to control pain.
• Lidocaine - a local anesthetic is used when needed.

Disease monitoring

Monitoring of the patient's condition includes regular assessments of the general condition, control of laboratory parameters such as the level of leukocytes and C-reactive protein. The prognosis depends on the timeliness of medical care and the presence of concomitant diseases. Complications may include further progression of infection, sepsis, intestinal obstruction, and the development of multiple organ failure.

Age-related features of the disease

Secondary peritonitis can progress differently in patients of different age groups:

• In children, the disease can progress rapidly due to the immaturity of the immune system and often requires prompt surgical intervention.
• In adults, secondary peritonitis is often associated with chronic diseases and may have a more protracted course.
• Elderly patients have a high risk of developing severe forms of the disease due to concomitant diseases and a decrease in the body's functional reserve.

Questions and Answers

• What is secondary peritonitis? Secondary peritonitis is an inflammation of the abdominal cavity caused by an infection that occurs as a result of damage or disruption of the tissues of internal organs.
