Introduction:

The skeletal muscle area (SMA) and prognostic nutritional index (PNI) are both considered as predictive parameters for mortality and morbidity for various type of cancer. In this study, we aimed to identify the effects of pre-operative SMA and PNI values on post-operative mortality and morbidity in patients with periampullary region tumors (PRT).

Methods:

Patients between 2010 and 2020 were retrospectively analyzed and divided into two groups according to SMA and PNI cutoff values. Univariate and multivariate analysis was performed to find potential risk factors.

Results:

The mean age was 65.94 ± 11.242 and 54 (60.6%) of the patients were male. Hypertension was found a reducing factor for morbidity in both univariate and multivariate analysis (p = 0.039; p = 0.045). Chronic obstructive pulmonary disease and low PNI were found as factors affecting mortality in univariate analysis (p = 0.046; p = 0.014). However, only low PNI was found as an enhancing factor for mortality in multivariate analysis.

Conclusion:

Although SMA is not a risk factor for post-operative morbidity and mortality, PNI can be considered as a risk factor for mortality in patients with PRT.
