Influence of dental status on postoperative complications in major visceral surgical and organ transplantation procedures—the bellydent retrospective observational study
Clinical Report: Impact of Oral Health on Postoperative Outcomes in Major Surgery and Transplantation
Overview
This retrospective study of 427 patients undergoing major visceral surgery and organ transplantation found that poor preoperative oral health is associated with increased postoperative complications, including infections and prolonged hospital stays. The findings highlight the importance of assessing and managing oral health prior to major surgical procedures to improve patient outcomes.
Background
Oral health and hygiene have been increasingly recognized as influential factors in systemic inflammatory diseases and surgical outcomes. Poor oral hygiene can lead to microbial dysbiosis and subclinical inflammation, which may exacerbate systemic conditions and increase the risk of postoperative complications such as wound infections, sepsis, and pneumonia. Despite evidence linking oral disease to adverse surgical outcomes, data remain limited and often biased, necessitating further investigation in larger patient cohorts.
Data Highlights
Parameter
Details
Study Design
Single-center, retrospective, exploratory
Patient Cohort
427 patients undergoing major visceral surgery or organ transplantation
Inclusion Criteria
Age ≥18, surgery between Jan 2018-Dec 2019, ICU/IMC treatment post-surgery, documented preoperative dental status
Exclusion Criteria
Minor/legal incapacity, incomplete dental data, intestinal surgery with contamination risk, pre-existing infection
Primary Endpoint
Incidence of postoperative complications within 30 days (Clavien-Dindo classification)
Secondary Endpoints
30-day mortality, length of hospital and ICU stay, infectious complications, microbial spectrum
Dental Status Classification
Good (normal/restored) vs Poor (prosthesis, loose, damaged)
Key Findings
Patients with poor preoperative dental status had higher rates of postoperative infectious complications.
Poor oral health was associated with increased length of hospital and intensive care unit stays.
Infectious complications included wound infections, pneumonia, and sepsis, with microbiological data supporting oral microbial involvement.
Preoperative oral health assessment was feasible and provided valuable predictive information for postoperative morbidity.
Exclusion of patients with intestinal surgeries minimized confounding from intraoperative microbial contamination.
Clinical Implications
Preoperative evaluation and management of oral health should be integrated into surgical care pathways for patients undergoing major visceral and transplant surgeries. Addressing poor oral hygiene before surgery may reduce postoperative infectious complications, shorten hospital stays, and improve overall patient outcomes. Multidisciplinary collaboration between surgeons, dentists, and intensive care teams is recommended to optimize perioperative care.
Conclusion
This study reinforces the significant impact of oral health on postoperative outcomes in major surgery and organ transplantation. Proactive oral health management represents a modifiable risk factor that can enhance surgical recovery and reduce morbidity.
