Work –up 11/9/00 Labs: CBC w/ Diff U/A Abd US Stool Guiac

Laboratory Values

Ultrasound Report Preliminary Report: The pyloric length measures 1.9cm. The muscle thickness is 3mm at the the upper limits of normal. The administration of sterile water PO, the pyloric channel is not noted to open in a normal fashion. Pyloric Stenosis is a strong diagnostic consideration.

Case Plan 11/9/00 Upper GI Series Surgery Consult NPO/IVF/NGT

Upper GI Series Pyloric canal upward, the base duodenal bulb concave, indicating pyloric stenosis.

Pyloric Stenosis 1.What is it? Hypertrophy of the smooth muscle of the pylorus, resulting in the obstruction of outflow 2. Risk Factors? Family Hx,firstborn males,decreased incidence in African-American population. 3. Average Age Usually from 2 weeks after birth to about 2 months.

Pyloric Stenosis 3.Symptoms: Increasing frequency of regurgitation /vomiting weight loss, decreasing frequency in stool,belching. 4.Signs: Abdominal mass or olive in the epigastric region,hypokalemia, hypochloremic metabolic alkalosis,icterus,visible gastric peristalsis, paradoxic aciduria,hematemesis.

Pyloric Stenosis 5.Diff Dx: Pylorospam, milk allergy hiatal hernia,GE reflux malrotation,duodenal atresia ect. 6.Diagnosis : Hx & Physical Exam US: elongated > 15mm pyloric channel and thickened muscle wall >3.5mm Barium swallow: string sign or double railroad tract sign.

Pyloric Stenosis 7.Initial Tx: Hydration & correction of Alkalosis 8.Definitive Tx: Fredet-Ramstedt pyloromyotomy-division of the circular muscle fibers w/o entering the lumen or mucosa. 9.Postoperative Complications: Bleeding, wound infxn, aspiration pneumonia

Pyloric Stenosis 10. Appropriate postoperative feeding: Between 6 to 12 hrs postoperative feeding w/sugar water advance to full strength formula over 24 hours. ( Blackbourne )
