Study Maps Postoperative Symptom Patterns After Oesophagectomy

Researchers analysed postoperative day 3 symptom reports from 1,047 adults who underwent oesophagectomy for oesophageal cancer at four hospitals in Anhui Province, China. The cross-sectional study, conducted from September 2023 to September 2025, used principal component analysis, latent profile analysis and symptom-network modelling. The symptom scale covered physical, psychological and social-functioning domains; in-silico perturbation simulations explored possible network effects of changing individual symptoms.

Four symptom dimensions were identified: somatic discomfort and fatigue, psychological distress, social-functioning impairment, and gastrointestinal or appetite-related symptoms. Latent profile analysis classified 80.2% of patients as having low symptom burden and 19.8% as having high burden. Reduced social interaction was the most central symptom in the overall network. Worry was most central in the low-burden profile, while incision pain was most central in the high-burden profile. Simulations suggested that alleviating somatic symptoms had the largest modeled effects; simulated aggravation patterns differed by symptom-burden group.

The results describe symptom patterns at a single early postoperative time point and do not show that targeting central symptoms improves recovery. Network centrality and perturbation effects are analytical findings, not tested interventions. The authors present the identified symptoms as candidates for future longitudinal and interventional studies.
