A retrospective study of 145 patients with sigmoid volvulus (SV) seen over a three year period is presented. Sigmoid volvulus (SV) was the commonest cause of emergency admissions with intestinal obstruction (56%). The mean age was 55 +/- 13 years, (range 10-80), and the male to female ratio was 13.5:1. The presence or absence of a previous attack makes a significant difference in the occurrence of gangrenous bowel. Eighteen out of 75 patients (24%) with no previous attack had gangrenous bowel compared with 2 out of 57 (4%) after recurrence. A conservative sigmoidoscopic detorsion was successful in the majority of the cases (63%). Elective surgery after bowel preparation was associated with a mortality rate of 3% in comparison to 12.5 mortality rate in patients with viable bowel operated on an emergency basis (p < 0.05). Sigmoidoscopic detorsion should be the first measure in patients with viable bowel.
本文介绍了一项对145例乙状结肠扭转（SV）患者进行的回顾性研究，这些患者是在三年时间内接诊的。乙状结肠扭转（SV）是肠梗阻急诊入院最常见的原因（56%）。平均年龄为55±13岁（范围10 - 80岁），男女比例为13.5:1。既往是否有发作史对坏疽性肠管的发生有显著影响。75例无既往发作史的患者中有18例（24%）发生坏疽性肠管，而复发后57例中有2例（4%）发生。大多数情况下（63%），保守的乙状结肠镜下扭转复位术是成功的。肠道准备后择期手术的死亡率为3%，而急诊对存活肠管进行手术的死亡率为12.5%（p < 0.05）。对于存活肠管的患者，乙状结肠镜下扭转复位术应作为首要措施。
