简要总结
This study investigates the effects of oral protein supplements on the nutritional status and quality of life in elderly patients following standard pancreatic resection. The research aims to determine whether these supplements can improve protein intake and contribute to better skeletal muscle mass, which is critical for recovery and overall health. The study hypothesizes that higher compliance with protein supplementation will be positively correlated with increased protein intake and improved muscle mass index, potentially leading to enhanced postoperative outcomes in this patient population.
详细描述
This study was a randomized, double-blind, placebo-controlled clinical trial conducted to assess the effects of oral protein supplements on nutritional status and quality of life in elderly patients following pancreaticobiliary surgery. The study included elderly patients aged 65 years or older who underwent surgery for pancreaticobiliary cancer. The trial was conducted between January 7, 2021, and July 18, 2022.
A total of 60 patients were initially enrolled, but after 19 dropouts, the final analysis was based on 41 patients (18 in the placebo group and 23 in the experimental group). The experimental group received protein supplements providing 18g of protein per day, while the control group received a placebo containing carbohydrates instead of protein.
Key outcomes such as nutrient intake, nutritional status, quality of life, muscle mass, muscle strength, and 10-meter gait speed were measured at three time points: before surgery, at discharge, and during an outpatient visit. The data were analyzed using a Linear Mixed-Effects Model to evaluate the effects of the intervention.

结局指标
主要结局
Muscle mass
时间窗: 1. The day before surgery (pre-OP), 2. Within 24 hours before the scheduled discharge date (DC; approximately 5 to 7 days postoperatively), 3. At the first outpatient visit following surgery (OPD; approximately 6 weeks postoperatively)."
Muscle mass was measured using the InBody S10 (InBody®, Seoul, Korea) device, which employs the Bioelectrical Impedance Analysis (BIA) method. Body Cell Mass (BCM), Phase Angle, and Skeletal Muscle Mass Index (SMI) were used for analysis. The SMI was calculated by dividing the appendicular skeletal muscle mass (ASM), which is the sum of the muscle mass of the limbs excluding the trunk, by the square of the height in meters \[SMI = ASM/height²\].
nutritional status
时间窗: 1. The day before surgery (pre-OP), 2. Within 24 hours before the scheduled discharge date (DC; approximately 5 to 7 days postoperatively), 3. At the first outpatient visit following surgery (OPD; approximately 6 weeks postoperatively)."
Nutritional status was assessed using the Patient-Generated Subjective Global Assessment (PG-SGA). This tool involves patient-reported changes in weight, food intake, symptoms affecting intake, and activity level. A dietitian then evaluates factors like diagnosis, metabolic stress, body fat, muscle mass, and edema to classify the patient's nutritional status as well-nourished (Grade A), moderately malnourished (Grade B), or severely malnourished (Grade C).
次要结局
- QoL(1. The day before surgery (pre-OP), 2. Within 24 hours before the scheduled discharge date (DC; approximately 5 to 7 days postoperatively), 3. At the first outpatient visit following surgery (OPD; approximately 6 weeks postoperatively).")
- Walking Speed(Indicators Related to Sarcopenia)(1. The day before surgery (pre-OP), 2. Within 24 hours before the scheduled discharge date (DC; approximately 5 to 7 days postoperatively), 3. At the first outpatient visit following surgery (OPD; approximately 6 weeks postoperatively).")
- Intake(1. The day before surgery (pre-OP), 2. Within 24 hours before the scheduled discharge date (DC; approximately 5 to 7 days postoperatively), 3. At the first outpatient visit following surgery (OPD; approximately 6 weeks postoperatively).")
