简要总结
The aim of this pilot study is to evaluate the potential benefits of nutrient supplementation on post-operative recovery for patients undergoing certain types of surgery, compared to those who do not receive such supplementation. The multi-center study will be conducted in Belgium and the Netherlands at UZ Brussel, Delta CHIREC, and Zuyderland Medical Center.
The pilot study will serve as a precursor to a randomized controlled trial and will include 200 patients. Participants must be classified as ASA I or II, aged between 18 and 65, and undergoing abdominoplasty, breast reduction, breast reconstruction through a DIEP-flap, or extensive circumferential liposuction and body contouring surgery.
Eligible patients who provide informed consent will be randomly assigned to either the intervention group, receiving R-Support supplementation, or the control group, without supplementation. Each group will consist of 100 patients. The study will span 8 weeks, with a 2-week preoperative period and a 6-week postoperative period. The treatment will involve a 28-day supplementation period, with R-Support Recover Prepare given 14 days preoperatively and R-Support Recover After given 14 days postoperatively.
Postoperative recovery will be assessed using the PRP-Questionnaire and Functional Recovery Index, which together will measure physical and psychological recovery, as well as the speed of recovery in the early postoperative phase. The study hypothesizes that the intervention group will experience quicker recovery than the control group. Additionally, data on hospital stay duration and early postoperative complications will be collected, with the expectation that better-prepared bodies will recover faster, potentially leading to fewer hospitalized days and complications. The study aims to demonstrate enhanced postoperative recovery, reduced early complications (such as wound dehiscence and infection), and shorter hospital stays.
详细描述
The aim of this pilot study is to assess the potential for enhanced postoperative recovery in patients receiving nutrient supplementation (intervention) before and after surgery, compared to patients who do not receive nutrient supplementation (control). This is a multi-center study taking place in Belgium and the Netherlands, with study sites including the following hospitals: UZ Brussel (BE), Delta CHIREC (BE), and Zuyderland Medical Center (NL).
This is a pilot study, with the end goal being a randomized controlled trial. A total of 200 patients will be included. The inclusion criteria are participants classified as ASA I or II, aged between 18 and 65, and undergoing one of the following types of surgery: abdominoplasty, breast reduction, breast reconstruction via DIEP-flap, or extensive circumferential liposuction and body contouring surgery.
Every patient who meets the inclusion criteria and provides informed consent will be randomly allocated to either the intervention or control group via a randomization algorithm: 100 patients without R-Support supplementation (control group) and 100 patients with R-Support supplementation (intervention group).
The study will last a total of 8 weeks, divided into a 2-week preoperative period and a 6-week postoperative period. The treatment period will be 28 days: 14 days preoperatively (supplementation with R-Support Recover Prepare) and 14 days postoperatively (supplementation with R-Support Recover After).
Data regarding postoperative recovery will be assessed using the PRP-Questionnaire and the Functional Recovery Index. These two questionnaires combined will provide a comprehensive overview of postoperative recovery, both physically and psychologically, as well as the speed of recovery in the early postoperative phase. The investigators hypothesize that the intervention group (with R-Support) will experience quicker postoperative recovery than the control group (without R-Support). Additionally, data on the length of hospital stay and early postoperative complications (minor, not requiring surgery, such as wound dehiscence <2 cm and localized infection; and major, requiring surgery, such as wound dehiscence >2 cm and infection requiring surgical debridement) will be collected. The investigators suggest that a body better prepared for surgery may, hypothetically, recover more quickly. This could be reflected in fewer hospitalized days and fewer wound complications. The study's endpoints are enhanced postoperative recovery, reduced early complications (wound dehiscence, infection), and shortened hospital stays.

研究组 & 干预措施
100 patients without R-Support supplementation (control group)
These patients will have no intervention, will not take the nutritional supplements
100 patients with R-Support supplementation (intervention group)
The treatment period for the intervention group will last 28 days, divided into two phases: 14 days preoperative and 14 days postoperative.
During the preoperative phase, participants will consume one shake per day. Each shake will consist of 35 grams (3 scoops) of R-Support Prepare mixed with 250 milliliters of water or milk. This regimen will be followed for 14 days leading up to the surgery.
During the postoperative phase, participants will consume one shake per day. Each shake will consist of 35 grams (3 scoops) of R-Support After mixed with 250 milliliters of water or milk. This regimen will be followed for 14 days following the surgery.
干预措施: R-Support Prepare & After nutritional supplement (Dietary Supplement)
结局指标
主要结局
Postoperative outcomes assessment: The Functional Recovery Index Questionnaire evaluates pain, social, lower limb, and physical activity, and the Postoperative Recovery Profile assesses physical, psychological, and social factors.
时间窗: 2 weeks postoperative
The Functional Recovery Index (FRI) focuses on pain and social activity, with a particular emphasis on lower limb mobility, which is often compromised after surgery. This tool aims to assess whether R-Support supplementation improves mobility and overall recovery. Recovery will be quantified using a scale from 0 to 10, where 0 indicates no difficulty at all, and 10 represents extreme difficulty.
Postoperative outcomes assessment: The Postoperative Recovery Profile (PRP) Questionnaire
时间窗: 6 weeks postoperative
The Postoperative Recovery Profile (PRP) Questionnaire assesses physical symptoms, functions, psychological aspects, social interactions, and activity levels. Patients will complete both questionnaires independently. Recovery will be quantified using a scale from 0 to 10, where 0 indicates no difficulty at all, and 10 represents extreme difficulty. It is hypothesized that patients receiving R-Support will experience a quicker recovery compared to those who do not.
次要结局
- Length of hospital stay(1 week postoperative)
- Early postoperative complication assessment(1 and 2 weeks postoperative)
