BACKGROUND: Gastrointestinal stromal tumors(GISTs) are rare mesenchymal tumors of the alimentary tract, most commonly affecting the stomach.
METHODS: We retrospectively reviewed the records of 1145 patients who underwent laparoscopic gastric banding between April 2004 and April 2008.
RESULTS: 4 patients (0.35%)(2 male, 2 female, mean age 46 years) were found to have GISTs. The tumors were detected intraoperatively, all of them located along the anterior aspect of the upper third of the stomach. All the tumors were excised laparoscopically and their mean size was 0.6 cm (range 0.7-0.5 cm). The histology showed longitudinal fusiform cells with no evidence of mitoses, atypia or necrosis. Immunohistochemically all the tumors were positive for CD117(c-kit) and were considered to have benign behavior.
CONCLUSION: Small GISTs found incidentally during laparoscopic gastric banding are benign in most of the cases. Proper inspection of the anterior stomach is necessary but in view of their benign nature wide wedge excision is not required.
