Based on neuronetwork computer technologies expert neuronetwork complex Axon was developed providing individual prognosis of ulcer disease and recommendations. The base of this expert system is information data base consisting of two blocks. The first block consists of detailed information about 634 patients with gastric ulcers (GU), the second block - about 417 patients with duodenal ulcers (DU). Control evaluation of the system demonstrated that the coefficient of sensitivity in patients with GU was 0,706 - 0,724, coefficient of specificity - 0,701-0,790. Coefficient of sensitivity in patients with DU was 0,765-0,817, coefficient of specificity - 1,000-0,877. The best neuronetwork evaluation was carried out in 57 new hospitalized patients. In 7 of 10 operated patients indications for surgery were based on combination of prognostic and clinical data. Only 2 (4,3%) of 47 patients demonstrated disagreement of prognostic and clinical data. In comparison of results of complications prognosis with real clinical results in surgical group 7 (70,0%) of 10 patients demonstrated agreement of these data. In 32 (74,4%) of 43 patients treated conservatively prognosis of complications corresponded to real clinical data.
基于神经网络计算机技术，开发了Axon专家神经网络复合体，用于提供溃疡病的个体预后和建议。该专家系统的基础是由两个模块组成的信息数据库。第一个模块包含634例胃溃疡（GU）患者的详细信息，第二个模块包含417例十二指肠溃疡（DU）患者的详细信息。对该系统的对照评估表明，GU患者的敏感性系数为0.706 - 0.724，特异性系数为0.701 - 0.790。DU患者的敏感性系数为0.765 - 0.817，特异性系数为1.000 - 0.877。对57例新入院患者进行了最佳神经网络评估。在10例接受手术的患者中，有7例手术指征基于预后和临床数据的综合判断。在47例患者中，只有2例（4.3%）的预后和临床数据不一致。在手术组中，将并发症预后结果与实际临床结果进行比较，10例患者中有7例（70.0%）的数据相符。在43例接受保守治疗的患者中，有32例（74.4%）的并发症预后与实际临床数据相符。
