Title: Gastric stump carcinoma as a long-term complication of pancreaticoduodenectomy: report
of two cases and review of the English literature.
Version: 0Date: 30 Aug 2017
Reviewer: Mehrdad Nikfarjam
Reviewer's report:
The authors describe two cases of gastric stump carcinoma following pancreaticoduodenctomy
and review the literature on the topic. Generally the cases are well presented and the paper is wellwritten. The authors appear to recommend possible screening for this complications, but based onthe rarity I don't know how they can justify this. Is there data after partial gastrectomy on thepossible need to screen for gastric stump malignancy? The authors should clarify exactly if theyhave a specific recommendation and how it is justified? eg Screening gastroscopy or Roux-En-Yanastomosis to reduce biliary reflux etc. Agree that one should be mindful to the diagnosis in thesepatients, but suggestions of routine screening gastroscopy is questionable and cannot be justifiedbased on 2 cases.
