Feeding tube dependence and postoperative complications in older adults after head and neck cancer surgery: a retrospective cohort study.
Article in BMC geriatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundElderly patients undergoing head and neck cancer (HNC) surgery represent a high-risk population due to age-related decline and multimorbidity, with increased vulnerability to complications. Dysphagia and nutritional compromise are common, adversely affecting recovery and outcomes. This study evaluated the incidence of postoperative dysphagia, enteral feeding requirements, and related complications in this population.
methodsWe retrospectively analyzed 46 patients aged ≥ 70 years who underwent major head and neck cancer surgery between 2019 and 2024. Clinical characteristics, tumor stage, nutritional status, and postoperative outcomes were collected. Enteral feeding strategies, including nasogastric tube (NGT) and percutaneous endoscopic gastrostomy (PEG), were evaluated. Dysphagia was assessed clinically and operationalized by the requirement for enteral feeding. Outcomes included feeding route at hospital discharge and at 3- and 6-month follow-up, duration of enteral feeding dependence, and postoperative medical complications. Statistical analyses comprised descriptive statistics and chi-square testing, with logistic regression used to identify predictors of PEG dependence.
resultsFourteen patients (30.4%) required PEG and 19 (41.3%) NGT, with conversion from NGT to PEG in 17.4% (n = 8). Of the 19 patients initially managed with a NGT, 8 (42.1%) subsequently required conversion to PEG, representing 17.4% of the total cohort. At discharge, 65.2% (n = 30) achieved full oral intake; PEG dependence persisted in 23.9% (n = 11) at 3 months and 17.4% (n = 8) at 6 months. Advanced T stage was the only significant oncologic predictor, associated with PEG placement (p < 0.001) and dependence at 3 (p = 0.001) and 6 months (p = 0.049). Regression confirmed advanced T stage increased odds of PEG placement (OR = 5.4) and long-term dependence (OR = 11.4), while reducing the likelihood of oral intake at discharge (OR = 0.15). Laboratory analyses showed significant postoperative changes: serum albumin declined (3.93 ± 0.50 to 3.59 ± 0.63 g/dL, p = 0.0002), hemoglobin decreased (12.64 ± 1.88 to 10.17 ± 1.86 g/dL, p < 0.0001), WBC rose (7.29 ± 2.82 to 9.07 ± 3.92 × 10⁹/L, p = 0.008), INR increased slightly (1.03 ± 0.09 to 1.08 ± 0.12, p = 0.018), and potassium decreased modestly (4.39 ± 0.49 to 4.20 ± 0.45 mmol/L, p = 0.016). Complications were frequent: electrolyte imbalances (22%), aspiration pneumonia (8.9%), delirium (8.7%), and wound complications (8.7%). Less common but clinically relevant were acute kidney injury (6.5%), venous thromboembolism (2.2%), and refeeding syndrome (2.2%).
conclusionsAdvanced T stage was the strongest predictor of PEG dependence in elderly head and neck cancer patients. Early nutritional screening and proactive multidisciplinary care, including geriatric assessment, are critical to reduce dysphagia-related morbidity and improving recovery.
