Overview
The most common cause of peritonitis is perforation of a hollow viscus such as perforation of the distal esophagus (Boerhaave syndrome), of the stomach (peptic ulcer, gastric carcinoma), of the duodenum (peptic ulcer), of the remaining intestine (e.g. appendicitis, diverticulitis, Meckel's diverticulum, IBD, intestinal infarction, intestinal strangulation, colorectal carcinoma, meconium peritonitis), or of the gallbladder (cholecystitis). Other causes of infected peritonitis include spontaneous bacterial peritonitis and disruption of the peritoneum, such as in cases of trauma, surgical wounds, continuous peritoneal dialysis, and intra-peritoneal chemotherapy. Causes of non-infected peritonitis include endometriosis, blunt abdominal trauma, gastric carcinoma, peptic ulcer, pelvic trauma, and pancreatitis.
Causes
Causes of peritonitis can be divided into infected and non-infected, which are as follows:
Infected peritonitis causes
| Perforation of a hollow viscus | Disruption of the peritoneum | Spontaneous bacterial peritonitis (SBP) | Systemic infections |
|---|---|---|---|
| Perforation of a hollow viscus (most common cause of peritonitis)
-perforation of the distal esophagus (Boerhaave syndrome) Other possible causes for perforation -Trauma, -Ingestion of a sharp foreign body (such as a fish bone) -perforation by an endoscope or catheter Most common organisms -mixed bacteria -Gram-negative bacilli (e.g. Escherichia coli), Anaerobic bacteria (e.g. Bacteroides fragilis) |
-Trauma Most common organisms -mixed bacteria Staphylococcus aureus, Coagulase-negative staphylococci, Fungi such as Candida |
peritonitis occurring in the absence of an obvious source of contamination. It occurs either in children, or in patients with ascites. |
e.g- Tuberculosis |
Non-infected peritonitis causes
| Leakage of sterile body fluids into the peritoneum | Sterile abdominal surgery | Rarer non-infectious causes |
|---|---|---|
| Sterile body fluids such as
-Blood(e.g.Endometriosis, Blunt abdominal trauma), Gastric juice (e.g.Peptic ulcer, Gastric carcinoma), Bile (e.g. Liver biopsy), Urine (e.g. Pelvic trauma), Menstruum (e.g. salpingitis), Pancreatic juice (pancreatitis), These body fluids are sterile at first, they frequently become infected once they leak out of their organ, leading to infectious peritonitis within 24-48h. |
Due to sterile foreign body inadvertently left in the abdomen after surgery (e.g. gauze,sponge) |
