BACKGROUND AND AIMS: Delayed gastric emptying after esophagectomy with gastric replacement can pose a significant postoperative problem, often leading to aspiration and pneumonia. The present study analyzes retrospectively the effectiveness of endoscopic pyloric dilatation for post-surgical gastric outlet obstruction.
METHODS: Between March 2006 and March 2010, 403 patients underwent a transthoracic en-bloc esophagectomy and reconstruction with a gastric tube and intrathoracic esophagogastrostomy. In patients with postoperative symptoms of an outlet dysfunction and the confirmation by endoscopy, pyloric dilatations were performed without preference with either 20- or 30-mm balloons.
RESULTS: A total of 89 balloon dilatations of the pylorus after esophagectomy were performed in 60 (15.6 %) patients. In 21 (35 %) patients, a second dilatation of the pylorus was performed. 55 (61.8 %) dilatations were performed with a 30-mm balloon and 34 (38.2 %) with a 20-mm balloon. The total redilatation rate for the 30-mm balloon was 20 % (n = 11) and 52.9 % (n = 18) for the 20-mm balloon (p < 0.001). All dilatations were performed without any complications.
CONCLUSIONS: Pylorus spasm contributes to delayed gastric emptying leading to postoperative complications after esophagectomy. Endoscopic pyloric dilatation after esophagectomy is a safe procedure for treatment of gastric outlet obstruction. The use of a 30-mm balloon has the same safety profile but a 2.5 lower redilatation rate compared to the 20-mm balloon. Thus, the use of 20-mm balloons has been abandoned in our clinic.
