Background:
A minimally invasive intragastric approach to the gastroesophageal junction (GEJ) allows resection of intramural disease while avoiding disruption of the lower esophageal sphincter and vagus nerves. Few surgeons use this approach; thus little is known regarding its indications, feasibility, technical aspects, complication profile, and long-term outcomes. This study reviewed the experience with this technique.
Methods:
A retrospective review was performed of a prospectively maintained, Institutional Review Board-approved database covering the period from January 1, 2005 to August 1, 2017. Indications, operative details, postoperative complications, and outcomes were assessed.
Results:
There were 12 patients identified. The mean age of these patients was 51.9 years. The indications for resection included 10 symptomatic leiomyomas, one gastrointestinal stromal tumor, and three cancers of the GEJ. Mean and median length of stay were 4.9 and 2.5 days, respectively. There were two postoperative esophageal leaks managed with laparoscopic repair. Of the 3 patients with cancer, 2 underwent an R0 resection, whereas 1 patient underwent an R1 resection. There were no other complications or recurrences. Mean follow-up was 6.0 years (range, 0.5 to 12.6 years); no patients had stricture or symptomatic gastroesophageal reflux on long term follow-up.
Conclusions:
Resection of selected intramural GEJ disorders through a minimally invasive transgastric approach can be performed safely with acceptable morbidity and good long-term results. The approach allows preservation of the lower esophageal sphincter and vagus nerves, a potential advantage compared with other surgical alternatives to resection in this region.
