Introduction. Surgery of congenital intestinal (duodenum) malrotation in children exists for almost 50 years, but only this decade it has been correctly codified as regards the intercurrent diagnoses, this possibility being strictly related to modern p araclinical assessment: ultrasounds, computed tomography scan, and other surgical technical possibilities. Aim of the study. Estimating clinical and paraclinical features of both medical and surgical treatment peculiarities in intestinal malrotation in chi ldren. Materials and methods. The paper was carried out in the clinic of the National Scientific and Practical Pediatric Surgery Centre N. Gheorghiu. The study includes the analysis of clinical and anamnestic data, prenatal and postnatal development data, environmental conditions, paraclinical tests, medical and surgical treatment in children with congenital malformations of small intestine, namely of duodenum. Results. Following the surgical treatment, under endotracheal anesthesia, it has been managed to perform the adhesiolisys based on bont method and electrocoagulation. Evolution was simple. After the surgery, these children followed a conservative treatment. Having a good general condition, with primary cicatrisation of wound, children have been disch arged Conclusions. Presently, developing new criteria for congenital malrotation diagnosis remains an insufficiently studied issue in the pediatric surgery. Prenatal diagnosis in these duodenal malformative types has improved a lot of patients’ forecasts. Management of surgical congenital disorders in children shows that currently duodenum anomalies in children continue to increase, due to little studied causes, with related complications that worsen both disease evolution and forecasts. Intestinal (duoden um) malrotation is a congenital anomaly due to disorder of rotation and fixing of duodenum, which interconnects the disorder of evacuomotor function of the duodenum and duodenostasis. The diagnostic algorithm of intestinal malrotation includes consecutive clinical manifestations, biological features, fibrogastroduodenoscopy, pH measurement, traditional lower gastrointestinal series and double contrast barium enema, and three dimensional duodenography by CT, peripheral ECEG. Studies show that surgical treatm ent techniques in intestinal malrotation continue to be developed. The surgical treatment is adapted depending on the form of malformation, clinical and evolutional stage of related complications.
