Coincidental Detection of Gastrointestinal Stromal Tumors During Laparoscopic Bariatric Procedures-Data and Treatment Strategy of a German Reference Center.

The incidence of incidental GISTs in our series was higher to what has already been reported. Risk of malignancy was low and resection as part of the bariatric procedure was considered as definitive treatment. Suspicious tumors should be removed and confirmed by histology. In case of GIST histology, tumor resection with negative margins may be weighed as complete oncological treatment if there is low risk of malignancy.
