ABSTRACT
Seventy-two patients underwent splenectomy for idiopathic thrombocytopenic purpura between 1979 and 1990. Mean age at splenectomy was 36.4 years (range 11-73). Indications for splenectomy were corticodependence in 21 cases and resistance to steroids in 44 cases. Thirty-five patients had platelet kinetic studies by 51Cr alloplatelets; 22 of them had splenic sequestration. Hematologic results were evaluated on discharge, at 3 months and in the long term (median follow-up 5.4 years). We had no mortality, morbidity was seen in 7% of the cases. None of the patients suffered from secondary infectious complications. 89% had good results on discharge (> 120 x 10(9)/l), 72.6% at 3 months and 90% on long-term follow-up. Factors associated with good response to splenectomy included a high postoperative platelet count (more than 120 x 10(9)/l on discharge), younger age at the time of surgery, preoperative corticodependence and predominantly splenic sequestration.

The usefulness of acid secretory data collected during a modified sham-feeding (MSF) test was examined in 50 patients suffering from duodenal ulcer before and after parietal cell vagotomy. In these patients basal acid output pentagastrin-stimulated acid output and MSF-stimulated acid output were measured. Preoperative MSF-stimulated acid output was found to be correlated with preoperative basal acid output, and postoperative MSF-stimulated acid output was correlated with both preoperative basal acid output and postoperative basal and pentagastrin-stimulated acid outputs. The addition of preoperative MSF-stimulated acid output to preoperative pentagastrin-stimulated acid output did not noticeably increase the close relationship between the latter and postoperative pentagastrin-stimulated acid output. It is concluded that basal and MSF-stimulated secretory rates overlap. Therefore, it is suggested that in both preoperative and postoperative conditions the addition of the sham-feeding test to the more simple basal and pentagastrin-stimulated studies could be discarded.
