Pneumoperitoneum refers to presence of free air within the peritoneal cavity, “Pneumoperitoneum induced Peritonitis” is synonymous of surgical pneumoperitoneum, as the leak of air and visceral contents contaminates the peritoneal cavity, producing peritonitis which mandates surgery. This entire pneumoperitoneum may result from inflammatory conditions, traumatic injury, neoplasia, anastomotic leak and vascular causes. The objectives of this study is to determine the incidence of Pneumoperitoneum-induced Peritonitis (surgical pneumoperitoneum) in emergency exploratory laparotomies, to identify the common anatomical sites of perforations and to review the pathological etiology of these cases. Review of 450 cases of emergency exploratory laparotomy cases performed in King Abdulaziz University Hospital from January 2011 to December 2015, among them 131 cases with radiologically documented pneumoperitoneum were selected to be involved in the study of surgical pneumoperitoneum, the anatomical site of perforation and the exact underlying pathology were documented. 29% of exploratory laparotomy cases were found to have pneumoperitoneum, mainly in the in the gastroduodenal region, inflammatory conditions as peptic ulcer disease or diverticulitis were the underlying cause of most of perforations. Pneumoperitoneum frequently indicates bowel injury or disease, hence it is called surgical pneumoperitoneum, Perforations are commonly found in gastro-duodenal area, the inflammatory conditions are responsible for the vast majority of cases, however presence of air with intact bowel, is called Non-Surgical or spontaneous Pneumoperitoneum, which has to be approached conservatively.
