The results of treatment of acute surgical diseases are worse in pregnant women, than in ordinary people, because of changes in patient’s organism. However, these patients would be treated the same way as ordinary patient according to conventional standards. The authors launched the special centre for treatment of acute surgical diseases of abdominal cavity for pregnant women and puerperas in order to provide the adequacy of treatment to the changes of patient’s organism. There was suggested a new standard of diagnostics, based on limited term (4-5 hours) with the following diagnostic laparoscopy or laparotomy in obscure cases. The experience of treatment of 171 patients with acute pancreatitis proved the high efficacy of the new strategy and developed standard of diagnostics. The main part of the patients were operated at the first 2-4 hours (105 patients - 61,4%) after hospitalization and 43 (25,1%) patients - within 4-6 hours. The cattaral form (92 patients - 53,8%) and phlegmonous (74 patients - 43,3%) form of the appendix changes were revealed in majority of patients. The gangrenous appendicitis was detected in 5 cases (2%). All the patients recovered. There wasn’t maternal or perinatal mortality.
