Gastric tube reconstruction reduces postoperative gastroesophageal reflux in adenocarcinoma of esophagogastric junction.

Background: The anastomosis of gastric remnant to esophagus after proximal gastrectomy is the traditional surgical treatment procedure for patients with types II and III adenocarcinoma of esophagogastric junction. However, the postoperative complications such as gastroesophageal reflux are frequent.

Aims: To assess the outcome of the intraperitoneal anastomosis of the reconstructed gastric tube to esophagus after proximal gastrectomy for types II and III adenocarcinoma of esophagogastric junction.

Methods: Seventy-six consecutive patients with preoperative diagnosis of type II or type III adenocarcinoma of esophagogastric junction were recruited. Forty-one patients had the traditional anastomosis of gastric remnant to esophagus and 35 patients underwent an anastomosis of esophagus to a gastric tube that was constructed from the gastric remnant after proximal gastrectomy.

Results: Twenty-three (56.1%) versus 12 (28.6%) patients (p = 0.016) complained various discomforts and/or were diagnosed with complications in the traditional group and gastric tube group, respectively, although there were no significant differences between the two groups in demographic data and pathological characteristics. Fourteen (34.1%) versus five (14.3%) patients (p = 0.046) complained of heartburn or acid regurgitation and nine (22.0%) versus two (5.7%) patients (p = 0.045) were confirmed reflux esophagitis in the traditional group and the gastric tube group, respectively.

Conclusions: The intraperitoneal anastomosis of the reconstructed gastric tube to esophagus demonstrates less complaints of gastroesophageal reflux and reflux esophagitis than the traditional anastomosis of gastric remnant to esophagus in the surgical treatment of types II and III adenocarcinoma of esophagogastric junction in 1-year follow-up.
