71.   Follow up assessment of shunt patency has been undertaken using transabdominal ultrasound.

72.   Patients were seen at routine clinic follow up and the reasons for surveillance explained.

73.   The published data show that most cancers are detected as a result of clinical follow up, where new symptoms are investigated at an early stage.

74.   In the good responder group, the improvement in continence was maintained throughout our follow up period.

75.   Twelve patients underwent intestinal resection during the first two years of follow up.

76.   The change in SDS for height during follow up varied according to the overall severity of gastrointestinal symptoms as defined in Table II and according to sex.

77.   One third of the children experienced no more than mild symptoms after initial treatment and were not subsequently treated with corticosteroids during the follow up period.

78.   Although the nature of the vagotomies surveyes in these reports is not stated, the follow up period is such that they must have been truncal vagotomies.

79.   Trauma during catheterisation seems unlikely, however, because the splenic artery remained permeable on follow up studies and catheterisation of the pseudoaneurysm was not performed.

80.   Our experience with this patient agrees with the view that many such patients can be managed conservatively with careful clinical and radiological follow up.
