The language of palliative surgery: A scoping review

Background

Despite an identified need for palliative surgery to have a clear definition and well-defined therapeutic goals, comprehensive assessment of utilization of the term palliative has not been performed in the surgical literature. The objective of this scoping review is to characterize use of the word palliative in reference to surgery performed for adult general surgery patients.

Methods

Four electronic databases were searched for peer-reviewed articles published from January 2000 to April 2023. Two independent reviewers extracted data and conducted a qualitative thematic synthesis of included studies. Representative analytic themes were generated and agreed upon by all authors.

Results

6906 studies were identified and 222 met inclusion criteria. 96.4% of studies were performed in oncology patient populations. Thematic synthesis revealed two domains: the language of palliative surgery and the evaluation of palliative surgery, each with associated themes. There was wide variability in the use and meaning of the term palliative. Many researchers reported survival as the sole outcome measure and very few studies utilized a validated instrument to quantify post-operative outcomes related to palliation. There was often a misalignment between the patient population, study objectives, study design, and conclusions drawn.

Conclusions

Disparate definitions of palliative surgery and poor study design compromise the validity of studies investigating palliative-intent surgery. Patient-reported and patient-centered outcomes are not routinely measured and lead to unwarranted conclusions. Consistent and accurate use of medical terminology, in addition to proper study design, is required to inform surgeons who counsel patients and families regarding the potential benefits of palliative-intent surgical interventions.
