A retrospective study of all ileogastrostomy procedures (n = 26) performed in 1993 by one surgeon (IGMC) was carried out to investigate the hypothesis that Helicobacter pylori may be implicated in certain severe cases of postoperation nausea and diarrhea. Ten of 26 persons (38.5%) displayed nausea and notable diarrhea (greater than or equal to ten bowel movements per day), seven of which warranted upper GI investigation. One hundred per cent (seven of seven) of these persons were found to possess H. pylori upon C-14 breath test. In four of six cases eradication therapy (1 g amoxicillin b.i.d./20 mg omeprazole b.i.d. for 2 weeks) corresponded with a resolution of severe nausea and diarrhea (one additional case involved omeprazole use only), suggesting that H. pylori should be considered as a possible cause of these symptoms post-ileogastrostomy. Additionally, in four of seven cases persons were re-tested (C-14 breath analysis) at least 1 month post-therapy and in this group three persons were found to be free of the organism. All three cases of notable diarrhea and nausea resolved with treatment, providing the strongest evidence for a possible association between infection and these symptoms.
