Preprocedural prognostic nutritional index predicts early gastrointestinal symptoms after percutaneous endoscopic gastrostomy or percutaneous radiologic gastrostomy in Korea: a retrospective cohort study: Yoonhong Kim, Jee Young Lee, Yeajin Moon, Seung Hun Lee, Kyung Won Seo, Ki Hyun Kim; Ann Clin Nutr Metab 2025;17(3):196-202. Published online December 1, 2025; DOI: https://doi.org/10.15747/ACNM.25.0032

Graphical Abstract Abstract PDF: Purpose
The prognostic nutritional index (PNI) reflects immunonutritional status and is a well-established predictor of surgical outcomes. Although its association with post-gastrostomy mortality has been documented, its relationship with early gastrointestinal (GI) symptoms remains unclear. This study aimed to evaluate whether the preprocedural PNI predicts early GI symptoms following percutaneous gastrostomy, including percutaneous endoscopic gastrostomy (PEG) and percutaneous radiologic gastrostomy (PRG).
Methods
This retrospective study included 71 adults who underwent PEG or PRG. Early GI symptoms, such as nausea, vomiting, and diarrhea, occurring within 7 days were recorded. The preprocedural PNI, neutrophil-to-lymphocyte ratio (NLR), and the C-reactive protein (CRP)-to-albumin ratio were analyzed using logistic regression to identify predictors. Receiver operating characteristic (ROC) analysis was performed to assess the PNI’s discriminative performance.
Results
Early GI symptoms occurred in 21 of 71 patients (29.6%). In univariate analysis, the PNI (P=0.009) and CRP-to-albumin ratio (P=0.018) were significant predictors, whereas NLR was not (P=0.125). After adjustment for potential confounders, including age, sex, body mass index, and NLR, the PNI remained an independent predictor of early GI symptoms (adjusted odds ratio, 0.90; 95% confidence interval, 0.83–0.98; P=0.021). ROC analysis for the PNI produced an area under the curve of 0.696, with an optimal cutoff value of 41.3 (sensitivity 70.6%, specificity 66.7%).
Conclusion
A lower preprocedural PNI is independently associated with the development of early GI symptoms after gastrostomy. The PNI may serve as a practical screening tool to identify high-risk patients who could benefit from preemptive nutritional optimization.

A practical guide for enteral nutrition from the Korean Society for Parenteral and Enteral Nutrition: Part II. selection and initiation of enteral feeding routes: Ja Kyung Min, Ye Rim Chang, Bo-Eun Kim, In Seok Lee, Jung Mi Song, Hyunjung Kim, Jae Hak Kim, Kyung Won Seo, Sung Shin Kim, Chi-Min Park, Jeongyun Park, Eunjung Kim, Eunmi Sul, Sung-Sik Han, Jeong Wook Kim, Seungwan Ryu, Minji Seok, Jinhee Yoon, Eunhee Kong, Youn Soo Cho, Jeong Meen Seo, for KSPEN Enteral Nutrition Committee; Ann Clin Nutr Metab 2025;17(3):165-171. Published online December 1, 2025; DOI: https://doi.org/10.15747/ACNM.25.0037

Abstract PDF: Purpose
We developed evidence-based recommendations for selecting and initiating the enteral nutrition (EN) delivery route in adult and pediatric patients to improve safety and standardize practice in Korea.
Methods
Key questions covered feeding tube selection, methods to verify tube placement, confirmation in pediatric patients, and timing of EN following percutaneous endoscopic gastrostomy (PEG). Recommendations were drafted and refined through multidisciplinary expert consensus under the Korean Society for Parenteral and Enteral Nutrition (KSPEN).
Results
Feeding tube selection should be based on gastrointestinal anatomy, function, and expected EN duration. Short-term feeding is recommended with nasogastric or orogastric tubes, whereas long-term feeding should use percutaneous or surgical routes such as PEG. Tube position must always be verified before use, preferably with radiography or pH testing; auscultation alone is unreliable and should not be used. In pediatric patients, radiographic confirmation remains the gold standard, although pH testing and insertion-length assessment may be considered when imaging is not feasible. After PEG, EN can be initiated safely within 4 hours in both adults and children without increasing complications if trained staff monitor for leakage or infection.
Conclusion
This guideline offers a structured framework for safe and timely EN tailored to patient characteristics. Early verification and multidisciplinary collaboration help reduce complication, improving outcomes of EN therapy.

A practical guide for enteral nutrition from the Korean Society for Parenteral and Enteral Nutrition: Part I. prescribing enteral nutrition orders: Ye Rim Chang, Bo-Eun Kim, In Seok Lee, Youn Soo Cho, Sung-Sik Han, Eunjung Kim, Hyunjung Kim, Jae Hak Kim, Jeong Wook Kim, Sung Shin Kim, Eunhee Kong, Ja Kyung Min, Chi-Min Park, Jeongyun Park, Seungwan Ryu, Kyung Won Seo, Jung Mi Song, Minji Seok, Eun-Mi Seol, Jinhee Yoon, Jeong Meen Seo, for KSPEN Enteral Nutrition Committee; Ann Clin Nutr Metab 2025;17(1):3-8. Published online April 1, 2025; DOI: https://doi.org/10.15747/ACNM.25.0002

Abstract PDF

Purpose
This study aimed to develop a comprehensive practical guide for enteral nutrition (EN) designed to enhance patient safety and reduce complications in Korea. Under the leadership of the Korean Society for Parenteral and Enteral Nutrition (KSPEN), the initiative sought to standardize EN procedures, improve decision-making, and promote effective multidisciplinary communication.
Methods
The KSPEN EN committee identified key questions related to EN practices and organized them into seven sections such as prescribing, delivery route selection, formula preparation, administration, and quality management. Twenty-one experts, selected based on their expertise, conducted a thorough literature review to formulate evidence-based recommendations. Drafts underwent peer review both within and across disciplines, with final revisions completed by the KSPEN Guideline Committee. The guide, which will be published in three installments, addresses critical elements of EN therapy and safety protocols.
Results
The practical guide recommends that EN orders include detailed elements and advocates the use of electronic medical records for communication. Standardized prescription forms and supplementary safety measures are outlined. Review frequency is adjusted according to patient condition—daily for critically ill or unstable patients and as dictated by institutional protocols for stable patients. Evidence indicates that adherence to these protocols reduces mortality, complications, and prescription errors.
Conclusion
The KSPEN practical guide offers a robust framework for the safe delivery of EN tailored to Korea’s healthcare context. It emphasizes standardized protocols and interdisciplinary collaboration to improve nutritional outcomes, patient safety, and operational efficiency. Rigorous implementation and monitoring of adherence are critical for its success.

Role of nutrition in wound healing and nutritional recommendations for promotion of wound healing: a narrative review: Myoungjean Ju, Yoonhong Kim, Kyung Won Seo; Ann Clin Nutr Metab 2023;15(3):67-71. Published online December 1, 2023; DOI: https://doi.org/10.15747/ACNM.2023.15.3.67

Abstract PDF

Purpose: Addressing both malnutrition and wound healing requires strategic intervention. However, guidelines for adequate nutrition for a variety of wounds are lacking. Based on the latest literature review, we summarize the role of nutrition in each stage of wound healing and nutritional recommendations for wound healing.
Current concept: Wounds undergo three healing phases: inflammatory, proliferative, and remodeling. The inflammatory phase involves clotting and cleaning the wound. The proliferative phase builds the wound bed through tissue growth. In the remodeling phase, collagen strength increases. Proper nutrition is crucial throughout. During inflammation, calcium, vitamin K, A, and E, zinc, and proteins are essential. In proliferation, amino acids, B vitamins, lipids, zinc, and iron play key roles. During remodeling, vitamins C and E, zinc, and water are critical for collagen synthesis and skin cell maturation. Vulnerable groups like the elderly, newborns, and obese patients need proper nutrition for skin maintenance. For pressure ulcers with malnutrition risk, recommendations are 30–35 kcal/kg/day energy, 1.25–1.5 g/kg/day protein, and 30 mL/kg water. Supplements might be added if regular meals don’t meet needs. For diabetic foot ulcers, despite common deficiencies, the 2019 International Working Group on the Diabetic Foot advises against prioritizing nutritional interventions over standard care due to limited high-quality evidence.
Conclusion: Despite limited guidelines, nutrition assessment is vital for wound evaluation. A multidisciplinary approach is key, emphasizing nutrition’s role in wound healing. Implementing nutritional interventions tailored to the wound and the individual’s nutritional status is essential. This comprehensive strategy ensures the best wound care outcomes.

Efficacy of monounsaturated fatty acids in reducing risk of the cardiovascular diseases, cancer, inflammation, and insulin resistance: a narrative review: Ki Hyun Kim, Yoonhong Kim, Kyung Won Seo; Ann Clin Nutr Metab 2023;15(1):2-7. Published online April 1, 2023; DOI: https://doi.org/10.15747/ACNM.2023.15.1.2

Abstract PDF

Purpose: The purpose of this review is to explore the potential benefits of monounsaturated fatty acids (MUFAs), specifically those found in olive oil, on weight loss, cardiovascular disease, cancer, inflammation, and insulin resistance. Additionally, this review examines the use of olive oil–based intravenous lipid emulsions (ILEs) in providing parenteral nutrition to patients with diverse needs.
Current concept: MUFAs, found in olive oil, nuts, and some animal foods, have been found to have numerous health benefits. A diet high in MUFAs can aid in weight loss and reduce the risk of cardiovascular disease. Olive oil, in particular, has been linked to a lower risk of cancer, inflammation, and insulin resistance. In addition, olive oil–based ILEs have been utilized for over two decades and are well tolerated by patients requiring parenteral nutrition.
Conclusion: A diet rich in MUFAs, specifically from olive oil, can provide numerous health benefits, including weight loss and reducing the risk of cardiovascular disease, cancer, inflammation, and insulin resistance. Additionally, olive oil–based ILEs have been shown to effectively provide nutrients to diverse populations requiring parenteral nutrition and have demonstrated the ability to preserve immune function and induce less lipid peroxidation than other ILEs. Further research is needed to fully understand the potential benefits of MUFAs and olive oil-based ILEs, but current evidence suggests that they may be a valuable addition to a healthy diet and medical treatment.

Major Surgery in Sarcopenic Patients: Kyung Won Seo; Surg Metab Nutr 2019;10(1):5-8. Published online June 30, 2019; DOI: https://doi.org/10.18858/smn.2019.10.1.5

Abstract PDF: Sarcopenia refers to reduced muscle mass in the elderly population, and this malady is of great interest in clinical course, including postoperative complications and mortality when treating major cancer in the elderly. The definition of sarcopenia varies according to the method of measuring muscle mass, and the skeletal muscle index (SMI) tends to be extensively used in retrospective studies. In many reports, sarcopenia has been reported to be a poor prognostic factor after gastrectomy, colectomy, pancreatectomy and liver transplantation, with regards to complications and the length of the hospital stay. Additionally, patients suffering from sarcopenia have a higher medical burden due to their poor clinical outcome after surgery. To overcome these difficulties, nutritional support and exercise training to improve sarcopenia before surgery is helpful, and so further studies that focus on these treatments need to be conducted.
