Popis: Background The aim of this study was to evaluate the impact of cervical lymph node dissection on acid and duodenogastroesophageal reflux (DGER) in patients undergoing transthoracic esophagectomy with gastric tube reconstruction and intrathoracic esophagogastrostomy. Methods Thirty one patients receiving transthoracic esophagectomy gastric tube reconstruction by intrathoracic esophagogastrostomy were subjected and divided into two groups: two field lymph node dissection group (the 2F group) and three field lymph node dissection group (the 3F group). All patients underwent 24h pH and bilirubin monitoring and gastrointestinal endoscopy one year after surgery. The results of 24h pH and bilirubin monitoring, endoscopic findings, and reflux symptoms, were compared between two groups. Results No acid reflux was observed in the 2F group, whereas it was observed in 6 (40%) of the 3F group (P = 0.023). DGER was observed in 2 patients (13%) of the 2F groups, whereas it was observed in 8 (53%) of the 3F group (P = 0.007). The percentage time of acid reflux in the 3F group was significant higher than that in the 2F group (median 0.8 vs 0%, P = 0.008). The percentage time of bile reflux in the 3F group was also significantly higher than that in the 2F group (median 2.600 vs 0%, P = 0.027). Four patients (25%) had reflux esophagitis in the 2F group, and nine patients (60%) had reflux esophagitis in the 3F group (P = 0.048). Conclusion Cervical lymph node dissection increases acid reflux and duodenogastroesophageal reflux, and can lead to the increase of the incidence of reflux esophagitis in patient with intrathoracic esophagogastrostomy.
