Letter to the Editor

We would like to express gratitude to Bilecik T. et al. and to Chiappetta S. et al. for their articles regarding the gastrointestinal stromal tumor (GIST) as a bariatric surgery incidental finding [1, 2]. By these means, we would like to share our experience regarding this relationship and, as already mentioned, to try as a surgical team to be aware and even search the connection between them.

The strong prevalence of the cells of Cajal at the gastric level, specifically in the fundus [3, 4, 5] so as the quick development of bariatric surgery, derives in a higher incidence of these diagnoses, either during or postoperatively through the biopsy results. Worldwide references talk about a prevalence between 0.3 and 1.2% of GIST in the biopsy specimen [6, 7, 8, 9, 10, 11, 12, 13] and 35 described observations [1, 2, 12, 14, 15, 16, 17, 18].

We present to you 12 cases which were retrospectively analyzed from a group of 50 well-experimented European laparoscopic surgeons. Demographic data...
