Eight cases of Infantile Hypertrophic Pyloric Stenosis collected in 10 years (1980-1989) in the Pediatric Surgery Unit of the Surgical Clinic of Dakar are reported. The rarity of this pathology among Blacks and a male predominance are noted. The clinical onset occurred after an average period of 3,25 weeks marked by food vomiting. At the start of the surgical management the age of patients was 6 weeks. X-ray examination following a barium meal showed no passage of contrast in 3 cases. However a narrowed and elongated pyloric canal was noted in 5 cases. Abdominal sonography was used in 3 cases and showed gastric stasis with a hypertrophy of pyloric muscle. A rammstedt pyloromyotomy was performed after a period of few hours to 13 days of resuscitation. A duodenal perforation complicated the operation twice and was subsequently repaired. In the post operative period, two patients died within 2-3 days. One of them had duodenal perforation. Six patients made a good recovery.

Hypertrophic pyloric stenosis (HPS) is one of the most common causes of abdominal surgery during the first weeks of life. The primary cause of the muscular hypertrophy is unknown and the pathogenesis is obscure. Clinically, vomiting is always present and sometimes there is a palpable pyloric mass (olive). Upper gastrointestinal tract study with barium has been the most usual method for the diagnosis. Since the first report of the use of ultrasound (US) in the diagnosis of HPS in 1977, this technique has been widely used and accepted, being by now, the diagnostic imaging examination of choice for infants in whom this abnormality is suspected. This is our experience with the use of US in 27 infants with clinically suspected HPS. In 17 cases there was US evidence of HPS and in 10 patients results were negative. We did not have false positive neither false negative results. We strongly recommend this diagnostic method for all infants under clinical suspicion of HPS.

One hundred barium meal examinations performed on infants of less than 4 months of age are reviewed. All the infants presented with vomiting as a major symptom and the diagnosis remained in doubt following the initial clinical assessment. Fifty seven per cent of the examinations showed an abnormality of which 45% were thought to be significant. Hypertrophic pyloric stenosis was demonstrated in 23 infants. Other abnormalities included hiatus hernia, gastro-oesophageal reflux, and duodenal abnormalities. The value of barium meal examinations in this group of infants is emphasised.

Hypertrophic pyloric stenosis (HPS) is a common medical emergency in newborns and lactating infants. Ultrasonography (US) is the diagnostic imaging procedure of choice in most centers, leaving the radiological study with barium for those cases in which US is negative and clinical symptoms persist or when other causes of vomiting must be discarded. We report our experience in 67 children (58 male) with suspected HPS. The US findings were consistent with HPS in 45 patients, and the diagnosis was surgically confirmed in all. In the remaining 22 patients with negative US findings, symptoms improved during follow up, with medical treatment. In one patient US was negative for HPS but showed an antral web, that was surgically confirmed. Since there were no false positive or negative results, the specificity and sensitivity of US for HPS diagnosis was 100%. We strongly recommend the use of US in patients with suspected HPS.

Hypertrophic pyloric stenosis is a gastrointestinal tract disorder common in infancy. The disorder causes projectile vomiting, weight loss, and fluid and electrolyte abnormalities. The problem can usually be diagnosed by clinical symptoms and manual detection of an enlarged pylorus. When the diagnosis cannot be confirmed by these methods, however, imaging studies are relevant. Until recently, plain radiographs and upper gastrointestinal contrast studies have been used to make the diagnosis, but ultrasonography is becoming the method of choice because it is highly accurate and lacks the ionizing radiation inherent in a radiologic procedure. Surgery provides a safe and effective treatment.

Hypertrophic pyloric stenosis (HPS) is very rare during the newborn period. Here we present a fullterm male neonate with abundant hematemesis 12 hours after birth which interrupted oral feeding. Bleeding subsided within three days after conservative measures, and oral feeding was restarted but not tolerated. The vomiting was effortless and nonbilious. An upper gastrointestinal series revealed gastric dilatation and partial obstruction of the gastric outlet. HPS was found by laparotomy on the fourth day and Fredet-Ramstedt pyloromyotomy relieved the gastric emptying. This is one of the few cases of HPS present at birth, which was diagnosed and surgically treated early, and we suggest a congenital etiology in previously reported cases of HPS. Hypertrophic pyloric stenosis (HPS) is a common cause of pediatric surgery. Usually young infants are involved; HPS is extremely rare in neonates and infants older than 6 months. Vomiting typically begins between the 3rd and 6th week of life, although some infants may have mild symptoms like regurgitation from birth.

Hypertrophic pyloric stenosis is commonly seen in infants 2 to 4 weeks old. We report a case of pyloric stenosis diagnosed in a boy 5 months and 11 days old suffering from the sudden onset of vomiting. Gastric volvulus was initially diagnosed at another hospital. Abdominal ultrasonography at first using an Acuson 5-MHz transducer revealed a negative diagnosis. However, a tubular pyloric mass measuring 5.5 mm in thickness, 15 mm in the transverse diameter, and 2.0 cm in length was detected by a 7-MHz transducer immediately after the infant vomited. On physical examination, no abdominal mass was palpable. This suggested that this might have been a case of hypertrophic pyloric stenosis which was missed until the infant was older than 5 months. We believe this is the oldest reported case of infantile hypertrophic pyloric stenosis in Taiwan.

Congenital hypertrophic pyloric stenosis, an important cause of intractable vomiting in infants is diagnosed clinically and confirmed ultrasonographically. Other useful interventions are plain radiography and barium study. Differential diagnosis includes pylorospasm and gastroesophageal reflux. Management protocol includes correction of dehydration and electrolyte imbalance and either Fredet Ramstedt pyloromyotomy or medical treatment with atropine sulphate. Atropine is initially given intravenously till vomiting is controlled and then orally at double the effective i.v. done for another 3 weeks. Atropine sulphate is generally well tolerated and side effects are few like tachycardia, raised SGPT and hyperthermia. Atropine sulphate is very effective, cheap, safe and perhaps more acceptable treatment option for CHPS.

Hypertrophic pyloric stenosis (HPS) is the most common surgical condition producing vomiting in infants. It has been reported as early as the 1st week of life. We report an infant with HPS seen on prenatal ultrasound. Although infants with HPS usually present between 3 and 5 weeks of life, HPS must be considered as part of the differential diagnosis of newborns with non-bilious vomiting.

Hypertrophic pyloric stenosis (IHPS) is the most common abdominal abnormality requiring surgery in infants. It occurs due to the hypertrophic and hyperplasia of the muscular layers of the pyloric. The usual age of clinical presentation is about three weeks of life. The most important symptom is non bilious emesis, intermittent or after each feeding. From march 1996 to June 2001, 21 infants, 20 males and 1 female, were subjected to ultrasonographic, radiographic exams and after diagnosis to the pyloromyotomy extramucosa. Ultrasonography was the study of choice used to identify hypertrophic pyloric stenosis; the markers to analyse were the length and the overall diameter of the pyloric canal and the muscle thickness of the wall. The results showed that a length of the pyloric canal 20 +/- 6 mm, a diameter 13.6 +/- 2.5 mm and a muscle thickness 4.1 +/- 1 mm are diagnostics for hypertrophic pyloric stenosis.
