This study aimed to determine the serum potassium concentrations in patients with sigmoid volvulus (SV), which is a rare large bowel obstruction.
The records of 86 patients with SV were reviewed retrospectively, while the records of 41 patients diagnosed with obstructive rectosigmoid cancer (ORC) were considered as the control group and as such, served as a source for comparison.
The analysis revealed a mean serum potassium concentration of 3.9 ± 0.6 mEq/L for the patients with SV, while the mean potassium concentration was 3.9 ± 0.5 mEq/L for the patients diagnosed with ORC (t:0.1, P>0.05). The number of hypokalemic and hyperkalemic patients identified in this study sample were 11 versus 5 patients and 1 versus 0 patients, respectively for the SV and ORC groups (x(2) = 0.1 and 0.5, respectively with a P>0.05).
No cause-and-effect relationship was observed between the serum potassium concentrations and SV. The serum potassium concentration is not pathognomonic for SV.
本研究旨在确定乙状结肠扭转（SV）患者的血清钾浓度，乙状结肠扭转是一种罕见的大肠梗阻。
回顾性分析86例乙状结肠扭转患者的病历，将41例诊断为梗阻性直肠乙状结肠癌（ORC）的患者病历作为对照组，作为比较的来源。
分析显示，乙状结肠扭转患者的平均血清钾浓度为3.9±0.6 mEq/L，而诊断为梗阻性直肠乙状结肠癌的患者平均钾浓度为3.9±0.5 mEq/L（t：0.1，P>0.05）。本研究样本中，乙状结肠扭转组和梗阻性直肠乙状结肠癌组低钾血症和高钾血症患者人数分别为11例对5例和1例对0例（x²分别为0.1和0.5，P>0.05）。
未观察到血清钾浓度与乙状结肠扭转之间存在因果关系。血清钾浓度对乙状结肠扭转无诊断特异性。
