Graphical Abstract Abstract PDF: Purpose
Pancreaticoduodenectomy (PD) is one of the most invasive procedures in gastrointestinal surgery. However, the clinical significance of postoperative tube feeding remains unclear. This study investigated the impact of enteral nutrition (EN) on the postoperative nutritional status of patients undergoing PD.
Methods
We retrospectively analyzed 129 patients who underwent PD at Tohoku University Hospital. Nutritional intake and status, evaluated using the Controlling Nutritional Status score, were compared between two groups: an EN group (97 patients) and a non-EN group (32 patients).
Results
There were no significant differences between the two groups in age, sex, body mass index, underlying diseases, operative duration, blood loss, postoperative pancreatic fistula, postoperative complications, delayed gastric emptying, or length of hospital stay. Although the EN group showed improvements in nutritional status both at discharge and compared with preoperative values, none of these changes reached statistical significance. Oral caloric intake was significantly higher in the non-EN group (P=0.01). In contrast, total energy intake was higher in the EN group, but this difference did not reach statistical significance (P=0.07).
Conclusion
Tube feeding after PD did not significantly influence postoperative nutritional status or overall nutritional intake. These findings suggest that EN offers no clear advantage over other approaches; however, further research is warranted to validate these results, refine existing guidelines, and optimize postoperative patient management.

Perioperative outcomes of older adult patients with pancreatic cancer based on nutritional status: a retrospective cohort study: Takanori Morikawa, Masaharu Ishida, Masamichi Mizuma, Kei Nakagawa, Takashi Kamei, Michiaki Unno; Ann Clin Nutr Metab 2025;17(1):66-74. Published online April 1, 2025; DOI: https://doi.org/10.15747/ACNM.25.001

Purpose
This study investigated the effects of preoperative nutritional status on postoperative outcomes in older adult patients with pancreatic adenocarcinoma.
Methods
The background and perioperative factors of patients who underwent pancreatectomy for pancreatic adenocarcinoma between 2007 and 2020 were retrospectively analyzed.
Results
Patients aged 75 years or over (older adults) were significantly associated with hypertension, upfront surgery, and lower prognostic nutritional index. In addition, these patients had a significantly lower rate of portal vein resection, less blood loss, and shorter operation time than patients aged less than 75 years (non-older adults). During the postoperative course, older adult patients had a higher rate of pneumonia and lower overall survival than younger patients, although recurrence‐free survival was comparable. In addition, older adult patients showed preoperative malnutrition as a risk factor for postoperative in‐hospital death.
Conclusion
Surgical treatment for pancreatic cancer in older adult patients was performed safely. However, preoperative malnutrition is a risk factor for in‐hospital death and such patients require nutritional support and less‐invasive surgery.
