Many different laparoscopic approaches to resection of gastric stromal tumor have been described in the literature. We reviewed our experience of laparoscopic approaches to surgical resection of gastric stromal tumors seven in six consecutive patients. The tumor locations were the gastric cardia (n = 2), gastroesophageal junction (n = 1), gastric fundus (n = 2), and gastric antrum (n = 2). Laparoscopic localization of endoluminal tumors included intraoperative endoscopy, laparoscopic ultrasound, and laparoscopic palpation. There were five males with a mean age of 57 years. Laparoscopic approaches to resection were laparoscopic wedge resection (n = 4) for tumors in the gastric fundus and antrum, laparoscopic enucleation (n = 2) for tumors in the gastric cardia, and transgastric endoluminal resection (n = 1) for a tumor located at the gastroesophageal junction. There was no conversion to laparotomy. The mean operative time was 143 +/- 54 minutes and mean blood loss was 57 +/- 27 mL. None of the patients required intensive care stay. The mean length of hospital stay was 3 days. There were no major or minor complications and no mortality. Surgical pathology demonstrated gastric stromal tumor with less than 2/50 mitosis per high power field in all seven specimens. Tumor size ranged from 2.8 cm to 7.1 cm in greatest diameter. There has been no tumor recurrence with a mean follow-up of 9 months. Laparoscopic resection of benign gastric stromal tumor is safe and feasible. The laparoscopic approaches to surgical resection should be tailored based on the location and characteristics of the tumor.
