21.   The need for gastroscopic follow up of pernicious anaemia patients is therefore still debated.

22.   In this study we evaluated the findings of follow up gastroscopies performed three years after primary gastroscopic screening of pernicious anaemia patients.

23.   The follow up gastroscopies showed two cases of adenocarcinoma.

24.   In the present follow up gastroscopy, the former patient harboured a new carcinoid tumour in a different location of the gastric corpus.

25.   There are some known premalignant conditions that might theoretically be used to identify those patients most in need of regular endoscopic follow up.

26.   However, the follow up period of three years is relatively short.

27.   Twelve patients in group A had recurrent episodes of ascending cholangitis during follow up compared with two patients in group B.

28.   All the patients were seen in consultation and laboratory tests performed at the end of the presently reported follow up.

29.   With an average follow up of eight months, no cases of reobstruction were seen in seven patients.
