Background and Objectives: Diabetic foot disease is a major cause of lower-limb amputation and is associated with substantial morbidity and mortality. While amputation is often considered definitive treatment, postoperative outcomes and their predictors remain incompletely characterized. Materials and Methods: This retrospective cohort study included all patients who underwent diabetic foot amputation at a tertiary care center between January 2015 and August 2025. Demographic data, comorbidities, laboratory parameters, and amputation-related variables were collected. The primary outcome was postoperative complications. Secondary outcomes included readmission, re-amputation, ICU admission, length of stay, and mortality. Logistic regression was used to identify predictors of postoperative complications. Results: A total of 437 patients were included (mean age 62.0 ± 11.8 years; 65.7% male). Postoperative complications occurred in 52.1% of patients, most commonly infections (31.6%) and acute kidney injury (18.1%). Readmission occurred in 50.6%, re-amputation in 23.4%, ICU admission in 28.7%, and mortality in 17.8%. On multivariable analysis, preoperative serum albumin was the only independent predictor of postoperative complications (aOR 0.944, 95% CI: 0.913–0.976; p < 0.001). Conclusions: Postoperative complications following diabetic foot amputation are common and associated with significant healthcare utilization and mortality. Preoperative hypoalbuminemia was the only independent predictor of postoperative complications, supporting its utility as an integrated biomarker of systemic illness (including inflammatory burden/infection and hepatic synthetic function) for perioperative risk stratification.

Background: Carotid endarterectomy (CEA) plays a critical role in stroke prevention, but assessing a patient’s preoperative physiological reserve remains challenging. This study aimed to evaluate the impact of sarcopenia and preoperative albumin on postoperative management outcomes and resource utilization in CEA patients with a high prevalence of metabolic comorbidities. Methods: This retrospective cohort study evaluated 67 patients who underwent elective or urgent CEA between January 2015 and June 2025. Sarcopenia was quantified using the Masseter Muscle Index (MMI) derived from routine preoperative head and neck computed tomography (CT) scans. Multivariable regression models were used to assess the relationships between the MMI, serum albumin levels, and surgical outcomes. Results: The cohort had a mean age of 66.8 years and demonstrated a significant metabolic burden, with a high prevalence of diabetes (71.6%) and an average body mass index (BMI) of 28.15 kg/m². Despite this predominantly overweight demographic, the MMI revealed underlying frailty and showed a strong inverse relationship with hospital resource utilization. A one-unit increase in the MMI significantly reduced total hospital length of stay (LOS) by 14.40 days (p = 0.001) and ICU LOS by 6.91 days (p < 0.001). Emergency surgery was the only independent predictor of mortality (OR 16.61, p = 0.047), while neither the MMI nor albumin significantly predicted short-term adverse clinical events. Conclusions: In a patient population where a higher BMI may mask underlying frailty, opportunistic screening for sarcopenia using routine preoperative CT scans provides important prognostic value. In this cohort study, a lower MMI showed an association with prolonged hospital and ICU stays; while it did not independently predict short-term mortality, its potential utility in forecasting resource utilization warrants further investigation in larger, prospective cohorts.
