Abstract

Background: Sigmoid volvulus (SV) is a significant gastrointestinal condition in sub-Saharan Africa, although its epidemiology and outcomes are poorly understood.

Objectives: To determine the prevalence, demographic characteristics, clinical presentation, and outcomes of SV in Malawi.

Methods: An 11-year retrospective review of patients with SV at Queen Elizabeth Central Hospital, Malawi. Patient records were analysed for demographic characteristics, clinical presentation, mode of management, and outcomes.

Results: We identified 301 cases of SV, with a prevalence of 27.3 cases per year. Males comprised 91.4% of cases, with a mean age of 51. Emergency presentations accounted for 69.8% of cases. Resection and primary anastomosis were the most common surgical procedures. The mortality rate was 11.3%, with non-viability of bowel being a significant predictor of mortality.

Conclusions: SV contributes significantly to the disease burden, particularly among middle-aged males seen in the surgical department. It presents acutely, and resection and primary anastomosis are the primary surgical approaches. Non-viability of bowel was identified as a significant predictor of mortality, emphasising the need for prompt surgical intervention.

Trial registration: Not Applicable.

马拉维乙状结肠扭转的流行病学、表现和结果：11年回顾性回顾。

背景：乙状结肠扭转（SV）是撒哈拉以南非洲地区一种重要的胃肠道疾病，尽管其流行病学和预后尚不清楚。目的：确定马拉维SV的患病率、人口学特征、临床表现和结果。方法：对马拉维伊丽莎白女王中心医院的SV患者进行为期11年的回顾性分析。分析患者记录的人口学特征、临床表现、管理模式和结果。结果：我们确定了301例SV，患病率为每年27.3例。男性占91.4%，平均年龄51岁。急诊占69.8%。切除和一期吻合是最常见的手术方法。死亡率为11.3%，肠道无活力是死亡率的重要预测指标。结论：SV显著增加了疾病负担，尤其是在外科的中年男性中。急性发作，切除和一期吻合是主要的手术途径。肠道无活力被认为是死亡率的重要预测因素，强调了及时手术干预的必要性。试验注册：不适用。
