Alteration of the oral environment in patients undergoing esophagectomy during the perioperative period

Abstract

Objective: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.Material and Methods:Thirty patients who underwent operation for removal of esophageal cancer in Tokushima University Hospital were enrolled in this study.Results: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.Conclusions: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.

New oral hygiene care regimen reduces postoperative oral bacteria count and number of days with elevated fever in ICU patients with esophageal cancer

“…Preoperative dental brushing can reduce the risk of postoperative pneumonia in esophageal cancer patients (4,8). In addition, postoperative care that includes control of oral bacteria may greatly improve outcomes of esophageal surgery (11). In most intensive care units (ICUs) worldwide, postoperative oral hygiene care is performed by nurses.…”

The potential of positron emission tomography/computerized tomography (PET/CT) scanning as a detector of high-risk patients with oral infection during preoperative staging

“…2 Oral care is effective in reducing hospitalization among patients with not only esophageal cancer but also various other cancers such as gastric cancer, lung cancer, and pharyngeal cancer. 3,4 However, oral care alone is not sufficient for these patients. In addition to this, aggressive dental treatment such as periodontal therapy, root canal treatment, and even tooth extraction are required for patients with severe oral infection during the intraoperative period.…”
