Clinical study of sigmoid volvulus at eleven core hospitals in the Kagawa Prefecture

Abstract

We analyzed the clinical features of 157 patients admitted to 11 institutions in the Kagawa Prefecture for volvulus of the sigmoid colon. The following were the background information of the patients:median age, 79.0 years;male-to-female ratio, 102:55;median body mass index, 20.0kg/m2;and the proportion of patients with performance status ≥3, 43.9%. Abdominal bloating and pain were the chief complaints. During hospitalization, endoscopy and endoscopic detorsion were performed 157 and 100 times, respectively. An accidental complication was observed in 3 cases, all of which were intestinal perforations. Surgery, which was indicated for ischemia, was performed in 62 of the 157 cases. Endoscopy is useful in the diagnosis of ischemia, which can be treated following an early diagnosis. Of the 157 patients, 19 died, whereas the rest were discharged. The risk factors for death were age ≥80 years and creatinine kinase level ≥200IU/L.
