Safety and feasibility of early oral nutrition after endoscopic treatment for patients with liver cirrhosis: A historical prospective and comparative effectiveness study

This study aimed to evaluate the safety and efficacy of early oral nutrition (EON) after endoscopic treatment compared with parenteral nutrition (PN) for patients with gastroesophageal variceal bleeding varices as cirrhotic complications.This historical prospective study enrolled patients from Qilu Hospital of Shandong University in China with gastroesophageal varices as cirrhotic complications and who were undergoing endoscopic therapy. A total of 197 patients who fasted for 4 h after treatment were prospectively enrolled as the ON group, whereas those who fasted >48 h were retrospectively matched in a ratio of 1:1 as the PN group. The primary end point was variceal rebleeding, whereas the secondary end points were mortality and adverse events during the 42-day follow-up. Hospitalization duration and expenses, levels of inflammatory factors, defecation time, and the satisfaction of patients were evaluated.During the 42-day follow-up, no significant difference was observed in the rate of variceal rebleeding (P = 0.586) and morality (P = 1.000) between the ON and PN groups. However, the average days of hospitalization (P < 0.001) and expenses (P < 0.001) were significantly decreased in the ON group. Furthermore, the serum C-reactive protein level (P = 0.002) and defecation time (P < 0.001) were lower and the satisfaction rate was higher (P < 0.001) for those in the ON group than for those in the PN group. Linear regression analysis showed that the tissue adhesive dosage was related to diet time (P = 0.038; 95% CI, 0.135-4.516).EON was proven to be safe and feasible and, hence, was recommended after endoscopic treatment in patients with cirrhosis.
