Patient flowchart: 30 patients were enrolled in the study and underwent PEG for long-term enteral nutrition after clinical, anthropometric, and laboratory evaluation. Duodenal biopsies were taken during the procedure for histologic and ultrastructure analysis. In total, 14 patients completed the study protocol, repeating duodenal mucosa assessment after 3–6 months of enteral refeeding. Normal healthy individuals submitted to upper GI endoscopy with duodenal biopsies were used as negative controls.Duodenal mucosa histology stained with hematoxylin and eosin (magnification 100×) exemplifying villi flattening measured at baseline in the patient (Duodenal mucosa histology stained with hematoxylin and eosin (magnification 100×) describing intestinal villi at T0 ((((Baseline characteristics of the patients.Optical microscopy analysis and follow-up of the 30 included patients. Villi length increased from T0 to T1 in all patients who completed follow-up, and an improvement in duodenal mucosa was observed in the few patients who displayed atrophy at baseline. Villi length could not be assessed in two patients in T0 due to severe artifact after mucosa sampling and processing.
