干燥综合征与食管功能障碍

目的 探讨干燥综合征(SS)患者食管功能障碍的表现形式以及与吞咽困难、实验室检查及其他辅助检查的关系.方法 采用定点牵拉法对31例SS患者及18名健康志愿者进行食管压力测定.结果 19例(61%)SS患者和4名(22%)健康对照出现上食管括约肌静息压减低,两组差异有统计学意义(p=0.008);15例(48%)SS患者存在食管体部蠕动异常,其中无效食管动力6例、"胡桃夹"食管动力3例以及非特异性食管蠕动异常6例.原发性SS与继发性SS患者食管体部各段蠕动波幅、时间和速度的差异无统计学意义.食管功能障碍与SS的临床表现、实验室检查及其他辅助检查无相关性.结论 SS可出现食管功能障碍,且呈现明显的多样性.

Sj(o)gren's syndrome and esophageal motility disorders

Objective To investigate the manifestations of esophageal motility disorders and evaluate the association between them and dysphagia, laboratory tests and other accessory examinations in patients with Sj(o)gren's syndrome (SS). Methods Esophageal manometry was performed in 31 patients with SS and 18 healthy volunteers by the step pull-through method. Results Decreased upper esophageal sphincter pressure was detected in 19 of the 31 patients (61%) with SS, while 4 of 18 (22%) in controls. The frequency was significantly higher in patients than in healthy controls (P=0.008). Fifteen of 31 patients (48%) showed various patterns of esophageal dysfunction including ineffective esophageal motility in 6 patients, nutcracker esophagus in 3 patients and nonspecific dysmotility in 6 patients. No major differences were found in esophageal parameters (peak amplitude, wave duration and velocity) when comparing primary SS with secondary SS. These esophageal abnormalities were not correlated with clinical manifestations, laboratory examinations and other auxiliary examinations. Conclusion Patients with SS may have esophageal motility disorders, which can presents with different patterns.
