Abstract

Background and Aim: Sigmoid volvulus (SV) is an uncommon cause of mechanical intestinal obstruction. This study was designed to review the outcomes of 859 SV cases. Methods: The records of 859 patients were reviewed retrospectively. Results: The mean age of the patients was 58.1 years, and 83.0% of the patients were male. Of the patients, 25.9% had a history of volvulus episode, and 25.6% had associated disease. The mean symptom duration was 39.4 h, and 13.5% of the patients were in shock state. The most common symptoms and signs were abdominal pain and tenderness (98.7%), distention (96.0%), and obstipation (92.3%); and the correct diagnosis rate was 71.9% based on the clinical findings. Abdominal X-ray radiograph revealed SV findings in 65.0% of the patients. When used, computed tomography, magnetic resonance imaging and sigmoidoscopy were diagnostic in all patients. Conclusion: Sigmoid volvulus is generally seen in adult men, and it tends to recur. Associated diseases and shock are generally major problems in patients with SV. It presents in the form of large bowel obstruction, and a triad of colic abdominal pain, asymmetrical distention, and obstipation is valuable for diagnosis. Plain abdominal X-ray radiograph may help the diagnosis, while Computed tomography, magnetic resonance imaging and flexible endoscopy are more useful. The diagnosis of SV is established by clinical, radiological, endoscopic and sometimes operative findings.
