阑尾切除后患者小肠细菌过度生长情况的研究

Study on small intestine bacterial overgrowth in patients after appendectomy

[目的]探讨阑尾切除后患者小肠细菌过度生长的情况。[方法]入选106例阑尾切除后患者,依据体检时右下腹有无疼痛分为有疼痛组、无疼痛组,分别进行氢呼气试验检查,记录小肠细菌过度生长情况,并与同期健康志愿者(健康对照组)情况进行对比分析。[结果](1)有疼痛组、无疼痛组、健康对照组的SIBO阳性率分别为44.8%、22.9%、3.3%,有疼痛组、无疼痛组与健康对照组的SIBO阳性率比较均差异有统计学意义(P<0.01);有疼痛组与无疼痛组SIBO阳性率比较差异有统计学意义(P<0.05);(2)有疼痛组、无疼痛组与健康对照组试餐后呼气氢浓度比较均差异有统计学意义(P<0.01),有疼痛组与无疼痛组的试餐后呼气氢浓度比较差异有统计学意义(P<0.05)。[结论]阑尾切除后患者若仍伴右下腹疼痛,应考虑有合并小肠细菌过度生长的可能。

[Objective]To investigate the excessive growth of intestinal bacteria in patients after appendectomy.[Methods]The totals of 106 patients with appendectomy were selected from the outpatients’ health checkups.According to the pain in the right lower abdomen during the physical examination,the patients were divided into two groups:painful and painless.The hydrogen breath test was performed to record the excessive growth of intestinal bacteria.And compared with the situation of healthy volunteers in the same period.[Results](1)There was significant difference between the two groups in the two groups after appendectomy and the healthy control group(P<0.01).(2)There was also a significant difference in the positive rate of SIBO between the pain group and the pain-free group in the right lower quadrant of the patient after appendectomy(P<0.05).[Conclusion]Clinically,patients with appendectomy should still have the possibility of excessive bacterial growth in the small intestine if they still have pain in the right lower quadrant.
