Criteria and Classification
In surgical practice, all complications are generally categorized by the time of their onset. Late complications are considered those issues that the patient encounters while at home, after discharge from the hospital.
Overall, all late complications are divided into two main categories:
- Organ complications — develop directly from the organs and systems on which the surgical intervention was performed.
- Local complications — develop in the area of the wound itself and the surgical access (in the operative area).
Complications Involving Operated Organs
This group of complications is directly related to changes in the anatomy and physiology of a specific organ after surgery. Depending on the type of surgery, the following specific syndromes and conditions are distinguished:
- Post-gastrectomy syndrome (operated stomach disease). This is a complex of functional and organic disorders that develop in patients after gastric resection or total removal of the stomach (gastrectomy).
- Postcholecystectomy syndrome. A specific condition that develops in some patients after gallbladder removal.
- Phantom pain. A severe complication occurring after limb amputation, where the patient continues to feel pain in the missing part of the body.
- Post-thrombotic syndrome. Forms as a consequence of previous thrombosis and manifests as chronic venous insufficiency.
- Adhesive disease (peritoneal adhesions). The process of pathological connective tissue cord (adhesion) formation in the abdominal cavity, which disrupts the normal mobility and functioning of internal organs.
Local Complications in the Surgical Site
Local postoperative complications are localized strictly in the area of surgical access (where the tissue incision was made). The most frequent late local complications include:
- Ligature fistula. This is a pathological tract (fistula) caused by an infectious process—suppuration of tissues around the suture material (ligature) left in the wound.
- Postoperative hernias. A condition in which internal organs protrude beyond their anatomical cavity. This occurs through a weak spot or defect formed in the area of the postoperative scar.
- Keloid scar. A pathological, excessive proliferation of connective tissue in the area of a healed wound, resulting in a coarse scar that rises above the skin and extends beyond the boundaries of the original incision.
Briefly: answers to topical questions
Which complications are classified as late local postoperative complications?
Late local postoperative complications that occur directly in the area of the surgical intervention after the patient is discharged from the hospital include the following pathological conditions.
- Ligature fistula — a fistula caused by suppuration around the suture material.
- Postoperative hernias — protrusion of organs through a defect in the scar area.
- Keloid scar — pathological proliferation of scar connective tissue.
What syndromes and conditions are classified as late complications involving the operated organs?
Late complications involving the organs on which surgery was performed include the following specific syndromes and conditions occurring after the patient's discharge from the hospital.
- Post-gastrectomy syndrome — a complex of disorders after resection or gastrectomy.
- Postcholecystectomy syndrome — develops after gallbladder removal.
- Phantom pain — occurs after limb amputation.
- Post-thrombotic syndrome — chronic venous insufficiency following thrombosis.
- Adhesive disease — formation of adhesions in the abdominal cavity.
What methods for the prevention of abdominal adhesive disease exist?
Prevention of abdominal adhesive disease is achieved by creating a smooth peritoneal surface during surgery.
To prevent adhesion formation, the following surgical methods and techniques are used:
- Reliable hemostasis — thorough cessation of bleeding in the surgical wound.
- Isolation of infected pathways — separation of potentially infected areas (e.g., the cervical canal) from the abdominal cavity.
- Peritonization — placement of a continuous surgical suture that hermetically connects the peritoneal leaves, as well as complete burial (extraperitonization) of the organ stump.
To remember the structure of late complications, use the "DEEP and OUTWARD" rule: "deep" refers to systemic reactions of the operated organs (adhesions, syndromes, phantoms), while "outward" refers to local defects of the access itself (hernias, scars, fistulae).
Class and exam questions
In what timeframe do late postoperative complications develop?
They occur in the late postoperative period, which begins after the patient is discharged from the surgical inpatient facility.
What is the cause of ligature fistula formation?
The cause is tissue suppuration that occurs around the surgical suture material (ligature) left in the wound.
How is adhesive disease classified?
Adhesive disease (formation of adhesions in the abdominal cavity) belongs to the group of complications involving the organs upon which the surgery was performed.
What is a postoperative hernia?
This is a local complication in which internal organs protrude through a formed defect in the postoperative scar area.
