[Computer-assisted analysis of the pressure behavior of the esophagogastric junction during increase in intragastric pressure]. / Rechnergestützte Analyse des Druckverhaltens am ösophagogastralen Ubergang während intragastrischer Drucksteigerung.

Two factors are to determine increasing lower esophageal sphincter pressure during intragastric pressure rising mainly: 1. the active intrinsic muscle tone and 2. the efficiency of the law by La Place. The purpose of the study was to estimate the part of both of them in this measurable phenomenon. We investigated 15 healthy volunteers and 5 patients post Nissen fundoplication. A simultaneous manometric examination of gaster and LES was carried out during gradual compression of abdominal wall. Analysis of dependence of LES-pressure on intragastric pressure, based on computer usage, was established. A linear equation described this dependence with the best correlation coefficient (r = 0.98) followed by potential and exponential equation. Fundoplication caused a steeper ascent without any changing of linear character of function. Considering linear equation is compatible with the law by La Place out not with a simultaneous pressure depending change of intrinsic muscle tone, these results indicate that the law by La Place has major importance in the measurable rising of high pressure zone during intragastric pressure increasing.

[Ileus of the small intestine caused by intestinal anisakiasis (herring worm disease)]. / Dünndarm-Ileus durch intestinale Anisakiasis (Heringswurmkrankheit).

Two cases of anisaciasis caused by eating of improperly prepared herrings which were infested with larval nematodes are reported. The acute type with a stenosing process in the small intestinal wall existed in both cases which resulted in an ileus. Therapy was resection of the affected intestinal part with end-to-end-anastomosis. The morphological proof of larval nematodes, which penetrate from lumen into the eosinophilic granulomata, pseudotumours and eosinophilic microabscesses are important histological findings. It should be considered the possibility of a herring worm disease in the case of an acute abdomen caused by an inflammatory small bowel stenosis.
