Emphysematous gastritis is a condition involving gastric wall inflammation, radiologic or intraoperative evidence of intramural gas, and systemic toxicity. A recent case of emphysematous gastritis in a 57-year-old diabetic man is reported, and 27 cases published since 1889 are reviewed. Predisposing factors include ingestion of corrosive substances (37%) and alcohol abuse (22%). Diagnosis of emphysematous gastritis is based on the clinical presentation of an acute abdomen with systemic toxicity and on radiographs demonstrating gas bubbles within the stomach wall. For the case reported herein, computed tomography was useful both in establishing the diagnosis and in following the resolution of emphysematous gastritis. Organisms most commonly involved were Escherichia coli (six cases), Streptococcus species (six cases), Enterobacter species (five cases), and Pseudomonas aeruginosa (three cases). The mortality was 61% (17 of 28 patients), and morbidity with gastric contractures occurred in 21% of cases (6 of 28). Optimal therapy has not been defined; however, antimicrobial chemotherapy and surgery, when appropriate, may improve survival rates.

Isolated internal iliac aneurysms are rare, and although most are of atherosclerotic origin the cause may also be congenital, traumatic, associated with pregnancy or infectious. A 56-year-old man presented with a swollen, painful left lower limb. Within a few days, weakness of the limb developed with fever and an acute abdomen with free air on x-ray. At emergency laparotomy a small perforation was found in the ascending colon. Examination of the left iliac fossa revealed a ruptured left internal iliac artery aneurysm. Extra-anatomic cross-femoral bypass grafting was done to revascularize the left lower extremity. The patient recovered without complication. At discharge the weakness had improved but knee flexion and extension were weak. Culture of the aneurysm contents grew Staphylococcus aureus and Pseudomonas aeruginosa. The authors discuss the presentation and management of infected internal iliac artery aneurysms.

Acute abdomen is an emergent condition in the emergency department, and it is mandatory to evaluate it immediately and treat it without delay. Pneumoperitoneum is usually attributed to perforation of the gastrointestinal tract. However, intra-abdominal, gynecologic, urologic, and miscellaneous pathogenesis not related to a perforated gastrointestinal tract had never been described in the past. Approximately 10% of pneumoperitoneum is not associated with hollow organ perforation. There are many imitators of pneumoperitoneum including subphrenic abscess, colon volvulus, Chilaiditi syndrome, and so on. In our case, the gas-forming bacterial peritonitis accounted for the pneumoperitoneum. We presented an 85-year-old man who received laparotomy due to peritonitis, and radiographic subphrenic free air was seen. However, a large amount of ascites was found rather than perforated bowels during the surgical exploration, and the culture of ascites was positive for Pseudomonas aeruginosa.
