Annular pancreas is a rare embryonal abnormality. Its manifestation in adulthood is often pinpointed with a substantial delay, which is most often attributed to pancreatitis, biliary pathology or dyspepsia. We present a case of a 28-year-old woman who had exacerbating symptoms of high bowel obstruction from 20th week of pregnancy, progressing after premature delivery. Diagnostic work-up revealed partial annular pancreas compressing the duodenum. Despite attempts of conservative treatment, her state deteriorated to such an extent that surgery was indicated and gastrojejunal bypass created. Her postoperative recovery was uneventful. In cases in which symptoms of high bowel obstruction in pregnancy persist and prostration occurs, we suggest close monitoring and a more thorough diagnostic approach. The question remains whether annular pancreas presents a cause of pathologic findings, a cofactor, or a mere accidental diagnosis in the development of superposed pathologies.

A definite intoxication develops as a result of a closed intestinal loop and toxic material accumulates in the closed loops. Much evidence has been submitted to show that this loop poison causes the intoxication observed after producing a closed intestinal loop. Sufficient evidence has been presented to prove that the essential poison is present in these closed intestinal loops, and usually in concentrated form. Chemical study of the contents of closed intestinal loops shows that a single substance or group of substances possesses toxic properties. This resists autolysis and pancreatic and ereptic digestion. It is thrown out of solution by five volumes of alcohol or by half saturation with ammonium sulphate. It is readily soluble in water and is not injured by boiling. It is not removed by dialysis. The method of isolation excludes practically all substances except primary proteoses. The characteristic resistance to digestive enzymes suggests a heteroproteose. Proteose intoxication in dogs gives a picture identical with that described after poisoning with intestinal loop fluid: early salivation and vomiting, followed by diarrhea and prostration, fall in temperature and blood pressure, and finally death in collapse. Autopsy shows essentially a splanchnic paralysis and remarkable engorgement of liver and spleen, but especially of the mucosa of the duodenum and small intestine. The blood shows great concentration due to loss of fluid and may remain incoagulable because of an excess production of antithrombin. Proteoses escaping from the blood are excreted in the urine. This toxic proteose concerned in intestinal obstruction has not yet been isolated in the urine, but may be excreted by the kidneys. This probably explains the clinical improvement and lessened intoxication noted after transfusion. Experimental evidence points to a primary proteose as the essential poison concerned in the intoxication of closed intestinal loops and intestinal obstruction.

Proteose injections in dogs cause vomiting, diarrhea, temperature reactions, low blood pressure, prostration, and, after large doses, an excess of antithrombin with incoagulable blood. A single proteose injection, for example one-half a lethal dose, causes abrupt clinical reactions in a normal dog with apparent complete recovery within 24 to 48 hours. The nitrogen elimination curve in a fasting dog under such conditions shows a great rise in total urinary nitrogen. The apex of the curve usually falls during the second 24 hour period following the injection. This rise may be over 100 per cent increase above the mean base-line nitrogen level. It does not fall promptly to normal but declines slowly in 3 to 5 days or more toward the original base-line (Text-fig. 1). This speaks for a definite cell injury with destruction of considerable protein substance due to a single proteose injection. The disturbance of cell equilibrium is not rapidly or promptly restored to normal. A dog which has received previous proteose injections is partially immune or tolerant to subsequent injections of proteose. These dogs, as a rule, show less intense clinical reactions and less rise in the curve of nitrogen elimination following a unit dose of standard proteose as compared with normal or non-immune controls. The proteose used in these experiments was prepared as described from material obtained in cases of intestinal obstruction or of closed intestinal loops. These experiments explain the sharp rise in blood non-protein nitrogen which follows within a few hours the injection of a toxic proteose. They also point to the correct explanation of the high non-protein nitrogen of the blood found in intestinal obstruction or with closed intestinal loops.
