Abstract
Background:
The treatment strategy for a gastrointestinal mesenchymal tumor located close to the esophagogastric junction remains controversial. The authors evaluate the criteria indicating that a gastrointestinal mesenchymal tumor is suitable for laparoscopic resection and assess the surgical techniques on the basis of clinical outcomes.
Methods:
The criteria specified a tumor more than 2 cm in diameter or a tendency for it to increase in size during the follow-up period. For eight patients in whom the tumor was located within 3 cm of the esophagogastric junction, an intragastric laparoscopic approach was used, whereas for seven patients in whom the tumor was further from the esophagogastric junction, an exogastric approach was used.
Results:
In all 15 cases, the laparoscopic resection was successful, with no complications. The intragastric group had a mean maximal tumor size of 2.9 cm, a mean operation time of 168 min, and a mean postoperative hospital stay of 8.8 days, whereas these values in the exogastric group, were respectively, 3.9 cm, 121 min (p = 0.0442), and 9.6 days. There were no recurrences in either group during the follow-up period.
Conclusion:
The good clinical outcomes suggest hat the criteria used as an indication for laparoscopic resection and the surgical techniques applied were appropriate for the resection of gastrointestinal mesenchymal tumors.
