Intestinal perforation, characterized by the disruption of the integrity of the bowel wall, represents a potentially severe complication arising from various disease conditions. Trauma, inflammation, instrumentation, infection, malignancy, ischemia, and obstruction are prevalent perforation triggers.
Swift identification and immediate intervention are imperative to avert the morbidity and potential mortality associated with peritonitis and the systemic complications stemming from the release of intestinal contents.
Epidemiology
The causes of a perforated viscus differ based on the patient’s age and geographical location. For instance, necrotizing enterocolitis is the predominant cause in premature infants, while appendicitis is a more frequent etiology in children and teenagers.
In adults, numerous causes exist without a specific gender predilection, and this article focuses on reviewing the causes observed in adults in developed countries.
Anatomy
Pathophysiology
Inflammatory conditions such as inflammatory bowel disease (Crohn’s disease and ulcerative colitis) can weaken the intestinal wall over time. Infections, especially severe and untreated ones, can lead to tissue necrosis and weaken the integrity of the intestinal wall. Reduced blood supply to the intestines, often due to mesenteric ischemia or thrombosis, can result in tissue damage and perforation.
Mechanical obstruction of the intestines, whether due to adhesions, tumors, or strictures, can lead to increased pressure within the intestines, potentially causing perforation. External trauma, such as a blunt or penetrating abdomen injury, can cause perforation.
Procedures or interventions, such as certain surgeries or diagnostic tests, may inadvertently lead to injury and subsequent perforation. Factors like inflammation, infection, or obstruction lead to an increase in intra-abdominal pressure. Prolonged pressure or compromised blood supply can cause tissue necrosis, making the intestinal wall susceptible to rupture.
Etiology
Infections: Severe infections affecting the gastrointestinal tract, such as certain types of bacterial or fungal infections, can contribute to tissue damage and perforation.
Trauma: Blunt or penetrating trauma to the abdomen, such as from accidents or injuries, can directly cause perforation.
Perforated Ulcer: Peptic ulcers, especially when left untreated or complicated, can perforate the wall of the stomach or small intestine.
Neoplastic Conditions: Malignant tumors in the gastrointestinal tract may invade and weaken the intestinal wall, increasing the risk of perforation.
Radiation: Radiation therapy, particularly when directed at the abdominal or pelvic regions, can cause damage to the intestinal tissue and lead to perforation.
Genetics
Prognostic Factors
Clinical History
Sudden and intense abdominal pain often localized initially but may become generalized. Guarding (muscle tensing) and rigidity of the abdominal muscles due to peritoneal irritation. Worsening pain upon the release of pressure (rebound tenderness) during a physical examination. Abdominal distension caused by the escape of air or contents into the peritoneal cavity. Systemic signs of infection, including fever and chills, as a consequence of peritonitis.
Nausea and vomiting may occur, often as a response to the underlying cause or peritonitis. Alterations in bowel sounds, such as hypoactive or absent bowel sounds, may be observed. The onset of symptoms is often sudden, especially in cases of traumatic injury or acute conditions like perforated appendicitis. The duration of symptoms can vary but tends to progress rapidly if left untreated. Timely intervention is crucial to prevent complications such as sepsis.
Physical Examination
The patient often experiences severe abdominal pain. The pain is typically acute, sharp, and may be diffuse or localized, depending on the perforation site. Tensing of the abdominal muscles, a defensive response to protect the affected area. Stiffness and resistance of the abdominal wall due to irritation of the peritoneum. Pain increases when pressure is released after palpating the abdomen.
It indicates peritoneal irritation. Swelling or bloating of the abdomen due to the accumulation of air or fluid in the peritoneal cavity. Reduced or absent bowel sounds may indicate paralytic ileus, often associated with perforation. Rapid heart rate may be present, reflecting the systemic impact of infection. Vomiting may occur in response to peritoneal irritation. A palpable mass or bulge may be felt, especially in cases where an abscess or localized collection is formed.
