Kirurgisk behandling av pylorusstenose

BACKGROUND: Pyloric stenosis is one of the most common surgical conditions in infants. This study aims to investigate diagnostics and results of surgical treatment for pyloric stenosis at Oslo University Hospital Ulleval. MATERIAL AND METHOD: A retrospective review of patient records for those undergoing surgery for pyloric stenosis in the period 2004-2016 was conducted. Preoperative symptoms and findings, diagnostics, treatment and postoperative results were recorded. Postoperative complications were classified according to the Clavien-Dindo classification. RESULTS: We identified 140 patients, 123 boys and 17 girls. The sensitivity for ultrasound examination at Oslo University Hospital was 96 % (135/140). Pyloromyotomy was curative in all the patients. A total of 12 perioperative and 12 postoperative complications were determined in 22 patients (16 %). There were four serious postoperative complications (grade IIIb and grade IVa), none of which caused sequelae. Mucosal perforation occurred in two patients and was diagnosed and sutured postoperatively. Postoperative wound infection occurred in seven patients. INTERPRETATION: The diagnosis of pyloric stenosis was confirmed by ultrasound examination in 96 % of the patients who underwent surgery for pyloric stenosis. Pyloromyotomy was curative in all the patients and there were few serious complications.
