During the perioperative period, oral ingestion is changed considerably in esophagectomy patients. The aim of this study was to investigate oral environment modifications in patients undergoing esophageal cancer treatments due to changes in dietary intake and swallowing functions.
Thirty patients who underwent operation for removal of esophageal cancer in Tokushima University Hospital were enrolled in this study.
It was found that 1) the flow rate of resting saliva decreased significantly at postoperative period by deprived feeding for one week, although it did not recover several days after oral ingestion began, 2) the accumulation of dental plaque and the number of mutans streptococci in saliva decreased significantly after operation, while both increased relatively quick when oral ingestion began, and 3) the swallowing function decreased significantly in the postoperative period.
These results suggest that dental professionals should emphasize the importance of oral health care and provide instructions on plaque control to patients during the perioperative period of esophageal cancer treatment.
食管癌患者在围手术期的经口摄入会发生明显改变。本研究旨在调查因饮食摄入和吞咽功能改变而接受食管癌治疗的患者口腔环境的变化。
本研究纳入了在日本德岛大学医院接受手术切除食管癌的 30 名患者。
发现 1）在术后一周的禁食期间，唾液的流速显著降低，尽管在开始经口摄入几天后仍未恢复，2）术后牙菌斑的积累和唾液中的变形链球菌数量显著减少，而在开始经口摄入后两者增加较快，3）吞咽功能在术后显著下降。
这些结果表明，牙科专业人员应在食管癌治疗的围手术期强调口腔卫生保健的重要性，并向患者提供菌斑控制方面的指导。
