[Post-resection dumping syndrome (case report)].

During the last twenty years a significant reduction of the number of gastric resections on account of peptic ulceration occurred due to better therapeutic possibilities in gastrodudodenal ulcers and due to changes in the epidemiology of gastric tumours. However, resections are made, frequently on account of complicated cases of unsuccessful treatment of ulcers in "treatment at any cost". This problem was frequently the subject of professional discussions. Therefore we consider it important to remind young colleagues of the omitted chapter of possible pathological conditions which develop after gastric resections. The latter include a group of vasomotor, gastrointestinal and humoral symptoms which develop as a result of the loss of reservoir function and the function of the closing mechanism of the pyloroantral part of the stomach after gastric resections in derivation surgery. In addition to data in the literature reporting that dumping syndrome is encountered only in 2-3% of any gastric operation the authors describe two of their own observations and the results of their surgical treatment.

[Absorption disorders following gastric resection--morphological and enzyme-histochemical observations on the small intestinal mucosa].

For the purpose of studying digestion and absorption disorders following stomach surgery, particularly with respect to membrane digestive functional disorders, morphological and enzyme-histochemical observation of the small intestinal mucosa was performed, and a comparison was done between the partial gastrectomy group (59 cases), and the total gastrectomy group (52 cases). The following results were obtained: 1) The small intestinal mucosa showed a tendency to significant villous atrophy in post-operative groups. 2) There was a significant decrease in the disaccharidase activity, especially in the small intestine of the total gastrectomy group. ALP, LAP and gamma-GPT activity also decreased, or disappeared in the small intestines showing villous atrophy. 3) In the atrophied mucosa which showed a marked decrease in membraneous enzyme activity, poorly-formed, irregularly sized microvilli accompanied by glycocalyx irregularity and disappearance were recognized under the electron microscope. The above mentioned morphological and enzyme-histological findings in the small intestinal mucosa, were strongly reflected in both post-operative progress and clinical symptoms.

[Malabsorption syndrome caused by Giardia lamblia in gastrectomized patients].

We report three adult patients with gastrectomy who had malabsorption caused by Giardia lamblia. Type II gastrectomy had been carried out in the three patients several years before, and the clinical presentation was similar: chronic diarrhea with malabsorption. A remarkable fact was that the search for parasites in feces was repeatedly negative in two patients, the protozoon being identified in the intestinal biopsy samples. In the third case, the diagnosis was made by the visualization of Giardia cysts in the feces.
