Acute gastric volvulus combined with pneumatosis coli rupture misdiagnosed as gastric volvulus with perforation: A case report.

Abstract

Background: Acute gastric volvulus represents a rare form of surgical acute abdomen, which makes it difficult to establish an early diagnosis. As the disease progresses, it can lead to gastric ischemia, necrosis, and other serious complications.

Case summary: This paper reports a 67-year-old female patient with a history of abdominal distension and retching for 1 day. After admission, a prompt and thorough examination was performed to confirm the diagnosis of acute gastric volvulus. Notably, the patient had free air in the abdominal cavity. The first consideration was gastric volvulus with gastric perforation, but the patient had no complaints, such as abdominal pain or signs of peritoneal irritation in the abdomen, and imaging examination revealed no abdominal pelvic effusion. Following endoscopic reduction, the abdominal organs, such as the stomach and spleen, returned to their normal anatomical positions, and the free intraperitoneal air disappeared, suggesting a rare case of acute gastric torsion. The source of free air within the abdominal cavity warrants careful consideration and discussion. Combined with the findings from computed tomography, these findings are hypothesized to be associated with the rupture of colonic air cysts.

Conclusion: Patients with gastric torsion combined with free gas in the abdominal cavity should consider nongastrointestinal perforation factors to avoid misdiagnosis.
