RESUMEN
Objective To review the diagnosis and treatment of pyloric canal polyp in infants and toddlers suffering progressive gastric outlet obstruction.MethodsClinical data of 5 male infants and toddlers,at age of 10 to 26 months(mean 15.6 months)with pyloric canal polyp admitted in our department from January 1993 to February 2009 were analyzed.ResultsOf 5 cases,the starting was acute and severe.the conservative treatment was out of effect and no any assistant examination was helpful during diagnosis,and every case was diagnosed clearly through exploratory laparotomy,cured with polypectomy and classic pyloroplasty.ConclusionCurrently,the exploratory laparotomy is an important way to diagnose pyloric canal polyp in infants and toddlers,while other assistant examination seems useless in this aspect.Polypectomy and classic pyloroplasty should be carried out during exploration,and it is dangerous for their life without correct therapy in time.
RESUMEN
Objective To evaluate the value of ultrasonic diagnosis of congenital prepyloric diaphragm. Methods Twelve cases were collected for the analysis of the characteristics of ultrasonography in diagnosis of congenital prepyloric diaphragm. Results Of the 12 cases of congenital prepyloric diaphragm, valvula in pyloric antrum could be observed in 5 cases, inclusive of 2 cases of complicating pachyntic stenosis of pyloric muscular layer. Other valvula in pyloric canal could not be found with ultrasonography. No pyloric muscular layer pachynsis was observed, but signs of pyloric obstruction such as gastric retention, slow or difficult transfer of gastric contents, gastro-esophageal reflux were found. Prepyloric diaphragm was confirmed surgically in all cases. Conclusion Ultrasonic diagnosis of congenital prepyloric diaphragm is of practical value in clinical practice and can provide reliable imaging data for the option of preoperative approaches.
