Abstract

Context: We investigated the prevalence of Helicobacter pylori infections in sleeve gastrectomy (SG) patients, as studies remain controversial in determining the necessity for histopathologic evaluation of all SG specimens. We also present a case of a 53-year-old woman with morbid obesity and complaints of regurgitation/heartburn whose SG specimen showed a 1.3-cm polyp, microscopically consistent with ectopic pancreatic polyp (see Figure 23, arrow), with an additional 36 juvenile/retention polyps. H pylori immune stain was negative in her acute inflamed gastric tissue. Design: A retrospective analysis was performed on SG cases signed out by 4 pathologists from 2017 to 2018. We calculated the percentage of H pylori positive cases out of the total number of SG cases. Results: A total of 223 cases were reviewed, of which 7.62% (n ¼ 17) were confirmed to be positive for H pylori infection based on immunohistochemical staining (detecting rate from 0% to 15% among 4 pathologists). Conclusions: Our data show a total of 7.62% positive cases for H pylori infection with a wide range of detecting rate among pathologists, indicating that SG specimens should be submitted for histopathologic evaluation, similar to other investigations. The acute inflammation most likely resulted from irritation of the large ectopic pancreatic polyp rather than H pylori infection in this case report.
